1.Heat treatment is the use of high temperature to evaporate volatile components in rubber formula materials, thereby reducing odor. For example, rubber formula materials can be heated at high temperatures for a period of time and then ventilated to reduce odor. 2.Water washing treatment is the use of water to clean the volatile components on the surface of rubber formula materials, thereby reducing odor. For example, the rubber formula material can be soaked in water for a period of time and then rinsed clean with water to reduce odor. 3.Vacuum degassing is the process of removing volatile components from rubber formula materials under vacuum conditions, thereby reducing odor. For example, rubber formula materials can be placed in a vacuum degassing device and degassed at a certain temperature for a period of time to reduce odor. 4.Ozone treatment utilizes the strong oxidizing properties of ozone to oxidize and decompose volatile components in rubber formula materials, thereby reducing odor. For example, rubber formula materials can be placed in ozone treatment equipment and treated under certain conditions for a period of time to reduce odor.

Due to the inert properties of silicone material and its low anti-static ability, silicone products have a headache inducing weakness in dust collection. So, what methods can be used to improve the dust prevention ability of silicone products? The most commonly used method by silicone product manufacturers is to spray hand feel oil; Below, Rongjin will talk to you about other methods besides spraying oil to deal with the weaknesses of silicone vacuum cleaners. 1. Add silicone anti-static agent (also known as silicone dust inhibitor), which compensates for the problem of low anti-static ability of silicone. 2. Spray a good hand feel oil (or PU oil), because silicone products are very rough and easy to stick to dust before spraying. After spraying, they are smooth and not easy to stick to dust. Furthermore, spray a hand feel+anti-static oil, which can achieve a large degree of non stick to dust.     The above two methods are the most direct and effective. Juguangli silicone product manufacturers can independently complete all silicone production processes such as silicone oil spraying and screen printing. Welcome customers to consult us.

To achieve the best quality of silicone buttons, the first step is to use good raw materials during production. Ensuring the quality of raw materials is one of the important factors in ensuring product quality, and it is also a prerequisite for achieving the best results during use. Therefore, as long as we can ensure the quality of raw materials during production, we will definitely be able to achieve the best results. Therefore, ensuring the quality of raw materials during production can provide us with real help. When producing silicone buttons, it is necessary to have very good quality assurance in order to gain more consumer recognition in the market. If we cannot have better quality in the production process, it will bring unnecessary impact to our production development. So, how can we ensure the best quality in the production process. The material of the buttons has a significant impact on the user's application experience, especially in products such as telephones, electronic toys, and remote controls that involve buttons. Traditional material buttons are no longer able to meet the high-quality needs of users. Therefore, the performance advantages of silicone buttons should be fully utilized, as this is of great help in improving the application experience. The key is to demonstrate strong comprehensive strength in many technical aspects such as button travel distance and silicone button product hardness. Given that the performance of buttons produced from different materials varies, it is necessary to pay attention to the comparison of materials and the measurement of performance in the actual selection process. Silicone buttons, on the other hand, have obvious advantages in terms of tactile comfort, which enables them to be widely installed and applied in different hardware devices. This is also a core element that demonstrates the level of technology and greatly helps improve the user's application experience. The key is to fully satisfy the demand for high-quality applications by leveraging the advantages of materials. As we all know, among keyboard products, the progressiveness in production technology has obvious advantages, but in the selection of materials, if there is no comprehensive comparison, it will not be able to ensure that the high-quality application needs are met accordingly, which is also the reason why silicone keys can be widely used and unanimously recognized in a short time. It is believed that consumers who have experienced this product have deep feelings about it, and can significantly improve the application experience. In addition to the need for high-quality raw materials, silicone button manufacturers also need to ensure the use of good production equipment when producing silicone buttons. During the production process, as long as these aspects of silicone products can be handled properly, it will definitely improve product quality. I know the best way to improve, and I believe this will definitely be very positive for us. Therefore, when producing products, we must ensure the use of very good equipment. If our equipment has already achieved success, we need to choose the latest equipment on the market, so that the quality of the product can be improved to the best.

Rolling forming: suitable for manufacturing simple sheet and plate-shaped products. It is a method of pressing rubber compound into film through a rolling machine called rolling molding. Some rubber products (such as tires, rubber tapes, hoses, etc.) use textile fiber materials that are coated with a thin layer of glue, and the gluing process is usually completed on a rolling mill. Fiber materials need to be dried and impregnated before rolling. The purpose of drying is to reduce the moisture content of the fiber material (to prevent water evaporation and foaming) and increase the temperature of the fiber material to ensure the quality of the rolling process. Immersion glue is a process before hanging glue, aimed at improving the bonding performance between fiber materials and rubber materials.   Extrusion molding: Used for more complex rubber products, such as tire treads, rubber tubes, and surface coatings on metal wires, which need to be manufactured through extrusion molding. Put the plastic mixture into the hopper of the extruder. Under the extrusion of the screw, a method of continuous shaping through various mouth shapes is used. Before extrusion, the rubber material is preheated to make it soft and easy to extrude, thereby obtaining rubber products with smooth surfaces and accurate dimensions.   The rubber industry is one of the important basic industries of the national economy. It not only provides essential light industrial rubber products for people's daily lives, but also offers various rubber production equipment or rubber parts for heavy industry and emerging industries such as mining, transportation, construction, machinery, and electronic products. It can be seen that the rubber industry has a wide variety of products, and the backward industries are very extensive. Compression molding: It is also possible to use compression molding to manufacture rubber products with complex shapes, such as cups and seals. With the help of molded molds, the rubber material is placed in the mold and heated to form.

How long can silicone kitchenware last? In modern kitchens, silicone kitchenware has gradually become the first choice for many families and professional chefs due to its unique advantages. They are not only heat-resistant and easy to clean, but also have the characteristics of softness, anti slip, and durability, greatly improving the convenience and safety of cooking. However, many consumers still have doubts about the durability and lifespan of silicone kitchenware.   The durability of silicone kitchenware is primarily attributed to its high-quality raw materials. Silicone is a polymer compound with excellent chemical and thermal stability. When manufacturing silicone kitchenware, food grade silicone raw materials are usually used to ensure the safety and harmlessness of the product. This material is not only resistant to high temperatures, but also has good flexibility and tear resistance, which can withstand various usage environments in the kitchen. Therefore, silicone kitchenware can maintain stability and durability for a long time under normal use.   The service life of silicone kitchenware is not fixed and is influenced by various factors. Firstly, frequency of use is one of the important factors affecting the lifespan of silicone kitchenware. Frequently used silicone kitchenware will age and wear out faster, especially in high temperature or acidic or alkaline environments, and its service life may be further shortened. Therefore, in order to extend the service life of silicone kitchenware, it is recommended to arrange the frequency of use reasonably and avoid prolonged continuous use, especially under extreme temperature conditions.   Maintenance and upkeep are also key factors affecting the lifespan of silicone kitchenware. The correct maintenance methods include regular cleaning, avoiding scratching with sharp objects, and avoiding contact with high-temperature flames. When cleaning, mild detergent and soft cloth should be used, and rough brushes or steel wire balls should be avoided to avoid scratching the surface of the silicone. At the same time, attention should also be paid to avoiding direct sunlight and humid environments during storage to extend the service life of silicone kitchenware.   In addition to frequency of use and maintenance methods, the lifespan of silicone kitchenware is closely related to its manufacturing quality and design process. High quality silicone kitchenware usually adopts advanced production technology and strict quality control to ensure that the product has good durability and service life. For example, some high-end silicone kitchenware undergoes multiple high-temperature vulcanization treatments during the manufacturing process to improve the hardness and wear resistance of the silicone. Meanwhile, reasonable design can also enhance the durability of silicone kitchenware, such as adopting thickened design and anti slip treatment.   In the practical application of silicone kitchenware, we can observe the impact of some common usage scenarios on its lifespan. For example, silicone spatulas often rub against the bottom of the pot when stir frying, which can easily cause surface wear. Silicone bowls and basins are more commonly used to hold food and are relatively less susceptible to physical wear and tear, but may also accelerate aging due to prolonged immersion in acidic or alkaline solutions. Therefore, when using silicone kitchenware, reasonable selection and use should be made according to its characteristics and purposes to extend its service life.   It is worth noting that silicone kitchenware from different brands and models may have differences in durability. Some well-known brands usually use higher quality raw materials and more advanced production processes, and their silicone kitchenware has a relatively longer service life. However, some low-quality or counterfeit products may use inferior silicone raw materials or rough production processes, resulting in products that are prone to aging, wear and tear, and even pose safety hazards. Therefore, when purchasing silicone kitchenware, consumers should choose legitimate brands and channels to avoid buying inferior products.   In addition to the above factors, the service life of silicone kitchenware is also influenced by personal usage habits and kitchen environment. For example, some people may be too rough or careless when using silicone kitchenware, resulting in product damage. However, excessively humid or greasy kitchen environments may also accelerate the aging process of silicone kitchenware. Therefore, when using silicone kitchenware, we should pay attention to cultivating personal usage habits and keeping the kitchen environment clean and dry.   The durability and service life of silicone kitchenware are influenced by various factors, including frequency of use, maintenance methods, manufacturing quality, design process, usage scenarios, as well as personal usage habits and kitchen environment.

The core role of silicone gloves in the kitchen is mainly reflected in the following five professional dimensions - each of which has undergone rigorous testing and user scenario verification, providing safe, efficient, and durable operational guarantees for home and commercial kitchens: 1. Extreme temperature protection (-40 ℃~230 ℃) Can instantly grab baking pans, frying pans, and freezers that have just been taken out of ovens (≤ 230 ℃) or refrigerators (≥ -40 ℃) to avoid burns or frostbite. Tested by a third-party laboratory (such as SGS), there is no significant deformation or heat penetration after continuous contact for 60 seconds at 230 ℃, which is much higher than ordinary cotton/rubber gloves (usually able to withstand ≤ 180 ℃). 2. Anti slip and stable grip The surface is made of food grade silicone with diamond shaped anti slip patterns, and the friction coefficient under wet or oily hands is ≥ 0.65 (ASTM D1894 standard), which is about 44% higher than ordinary cotton gloves (≤ 0.45). It can firmly hold smooth glass baking bowls and stainless steel cookware, reducing the risk of tableware slipping, especially suitable for scenarios where non stick pans/ceramic tableware are used. 3. Oil proof, stain proof, easy to clean Oil repellent and hydrophobic properties: The adhesion of edible oil (such as soybean oil) decreases by 60%, and it can be washed clean immediately to prevent oil stains from penetrating the fibers (traditional cotton gloves are prone to bacterial growth). It can be directly placed in a dishwasher (resistant to ≤ 90 ℃) for cleaning, or disinfected with alcohol, in compliance with HACCP food safety standards, reducing the risk of cross contamination. 4. Ergonomics and Durability Three layer composite structure: food grade silicone outer layer (thickness 1.2mm)+glass fiber insulation layer (thickness 0.5mm)+comfortable lining, overall weight ≤ 120g, lightweight to wear. After 10000 bending tests without cracks, the lifespan of PVC gloves is extended by 3-5 times compared to ordinary PVC gloves, significantly reducing replacement frequency and cost. 5. Multi scenario compatibility Baking: Take the hot baking tray directly, stir the dough, and knead the high-temperature ingredients. Barbecue: Flip the meat on the grill and move the charcoal grill. Freezing: Split frozen meat chunks and quickly process ice packs to prevent frostbite. Daily: Twist open tightly sealed bottles and cans, hold the partition of the steaming box, and improve operational convenience.   Silicone gloves have become an indispensable protective tool in modern kitchens, ensuring operational safety and improving cooking efficiency, helping families and catering practitioners achieve higher standards of food safety management.

Silicone rubber products are believed to be familiar to everyone. Some products can be directly used after being molded, while others require secondary vulcanization (also known as secondary sulfurization). Actually, after molding, it looks good to the naked eye and can be used normally. Why do we need to undergo secondary vulcanization? Firstly, it should be noted that not all silicone rubber products require secondary vulcanization of silicone. However, depending on the formula of the raw materials, some can be directly molded in one go, while some special materials such as fluororubber products and EPDM silicone rubber products require secondary vulcanization. This is because during the primary vulcanization of these materials, the peroxides inside will decompose and undergo high polymer reactions, producing some low molecular weight compounds (such as benzene, benzoic acid, etc.). These low molecular weight compounds mixed with rubber will reduce the mechanical properties and lifespan of silicone rubber, and are also toxic. This is very unfavorable for silicone kitchenware, so silicone rubber product manufacturers often use secondary vulcanization to decompose and evaporate low molecular weight compounds. Secondly, after the first vulcanization is completed, the silicone molecules may not be fully crosslinked (vulcanization is insufficient). Secondary vulcanization of silicone rubber can make it more fully and evenly vulcanized, thereby improving the mechanical properties and durability of the rubber. Thirdly, it can be subjected to silicone secondary vulcanization, such as the EPD silicone rubber products widely used in automobiles, which can remove odors and improve the comfort of car passengers after secondary vulcanization. Fourthly, in order to reduce costs and increase production capacity, silicone product manufacturers often shorten the first silicone vulcanization time and then extend the second vulcanization time to ensure that the products are fully vulcanized while also improving their competitiveness.

In the daily production process, various problems are encountered, and bubbles are a common one. Some bubbles are on the surface of rubber products, while others are inside. There are many reasons for their occurrence. Next, Kexin, a silicone protective cover manufacturer, will share the reasons with you as follows: 1. The problems with the raw materials themselves may be due to poor quality, formulation matching issues, or excessive moisture in the materials (which can be solved by adding some calcium oxide during mixing). It is recommended that the manufacturer eliminate them one by one, 2. Improper operation can lead to insufficient or uneven rubber mixing, which can be avoided by improving the operation manual. A complete and compliant operation manual is the most basic requirement for rubber product manufacturers, 3. The problem of exhaust first needs to be ruled out whether there is a process of setting exhaust during the processing. Secondly, there is a problem with the mold itself. If the mold does not have an exhaust groove, or the exhaust hole design is unreasonable, or if it is blocked by foreign objects, bubbles will also be generated 4. Problems during vulcanization, such as insufficient vulcanization time, insufficient pressure during vulcanization, or high impurities in the vulcanizing agent, can also generate bubbles 5. The product is too thick, which slows down the heat transfer of the rubber. In the end, only the outer surface is vulcanized, while the inside is filled with bubbles   Other suggestions 1. Slow down the injection speed of the material, and excessive injection speed during the processing is also an important reason for the generation of bubbles. 2. We know that the generation of bubbles is due to the entry of air, and the solution is to prevent air from entering. Therefore, a more thorough solution is to replace the vulcanization molding machine with a vacuum molding machine.

What are the precautions for using silicone tableware? In daily life, tableware is the item that comes into contact with food the most frequently, and the selection and safety of its material are highly concerned. In recent years, silicone tableware has gradually gained popularity among consumers due to its non-toxic, odorless, high-temperature resistant, and easy to clean characteristics. However, despite the many advantages of silicone tableware, there are still some precautions to be taken during use to ensure its safety and durability.   The high temperature resistance of silicone tableware is one of its highlights, but this does not mean that it can be placed in extreme high or low temperature environments at will. Generally speaking, silicone tableware can withstand temperatures ranging from -40 ℃ to 230 ℃, and it is safe to use within this range. However, if exposed to an environment beyond this temperature range for a long time, silicone may undergo deformation or aging, affecting its service life. Therefore, when heating or freezing silicone tableware, it is advisable to avoid exceeding its tolerance temperature as much as possible to avoid affecting its performance.   When using silicone tableware, it is also important to avoid contact with sharp or rough objects. Although silicone is soft and has a certain degree of elasticity, long-term exposure to sharp objects or rough surface wear can also lead to surface scratches or damage. This not only affects aesthetics, but may also accumulate dirt and affect hygiene. Therefore, when using silicone tableware, direct contact with sharp objects such as knives and spatulas should be avoided as much as possible to avoid scratching the surface. Silicone tableware also needs to pay attention to some details during the cleaning process. Due to the silicone material's resistance to absorbing grease and stains, it is relatively easy to clean. However, it should be noted that rough cleaning tools or strong detergents should be avoided to prevent damage to the silicone surface. At the same time, after cleaning, ensure that the tableware is completely dry and avoid prolonged immersion in water to prevent the growth of bacteria. When storing silicone tableware, attention should also be paid to avoiding direct sunlight and humid environments. Direct sunlight can accelerate the aging of silicone materials, while humid environments may trigger the growth of mold. Therefore, it is recommended to store silicone tableware in a cool and dry place, and use sealed bags or storage boxes to keep it dry and hygienic. In addition to the above points, attention should also be paid to the scope of application of silicone tableware. Although silicone tableware has many advantages, it is not suitable for all occasions. For example, when heating food in a microwave oven, it is advisable to avoid using silicone tableware as much as possible, as the heating method may cause heat accumulation inside the silicone tableware, leading to deformation or damage. In addition, for certain dishes that require prolonged high-temperature heating, it is not recommended to use silicone tableware to avoid exceeding its temperature tolerance range. Special attention should be paid to silicone tableware used by infants and young children. Due to the weaker resistance of infants and young children, they also have higher hygiene requirements for tableware. Therefore, when choosing silicone tableware for infants and young children, it should be ensured that it meets relevant national safety standards and undergoes regular disinfection treatment. During use, attention should also be paid to observing whether the tableware is damaged or deformed, and if found, it should be replaced in a timely manner. It should be noted that although silicone tableware has many advantages, not everyone is suitable for use. For some people who are allergic to silicone materials, using silicone tableware may cause allergic reactions. Therefore, an allergy test should be conducted before use to ensure that you will not experience any allergic reactions to it.  

1.Basic principles Hot pressing is an important process in the processing of silicone products. Silicone itself is made from silicone rubber raw material, which is a polymer with high elasticity. During the hot pressing process, silicone rubber is placed in a specific mold, and by heating and applying pressure, the silicone rubber flows inside the mold and fills various parts of the mold, thereby forming the desired shape of the silicone product. The main principle is to use thermal energy to make the molecular chains of silicone rubber more active, reduce their viscosity, and make them more fluid. At the same time, pressure helps silicone rubber better fill the gaps in the mold, ensuring that the molded product is dense and complete.   2.Process steps Preparation stage Firstly, it is necessary to choose suitable silicone rubber raw materials. Select the appropriate silicone rubber formula based on different product requirements, such as hardness, temperature resistance, color, etc. For example, for silicone products that require high hardness, silicone rubber with higher cross-linking density will be selected; For products that require high temperature resistance, corresponding high temperature resistant additives will be added. At the same time, the mold should be cleaned and preheated. Molds are usually made of metal (such as aluminum alloy, steel, etc.), and cleaning is to remove impurities, oil stains, etc. on the surface of the mold to prevent affecting the forming quality. Preheating the mold can accelerate the vulcanization speed of silicone rubber and reduce the molding time. The preheating temperature is generally around 100-200 ℃, depending on the type of silicone rubber and the characteristics of the product. Forming stage Place an appropriate amount of silicone rubber into the mold cavity. This' appropriate amount 'is precisely calculated to ensure that the mold cavity can be completely filled without causing excessive overflow. Then close the mold and place it into a hot pressing equipment (such as a flat vulcanizing machine). Then start heating and pressurizing. The heating temperature is usually between 150-250 ℃, and the pressure is generally around 5-20mpa. Under high temperature and pressure, silicone rubber undergoes vulcanization reaction. The vulcanization reaction is the process of forming cross-linking bonds between the molecular chains of silicone rubber through cross-linking agents, transforming the silicone rubber from a plastic state to a highly elastic solid state. This process usually lasts from a few minutes to several tens of minutes, depending on factors such as the formula of the silicone rubber, the size of the mold, and the thickness of the product. Post processing stage When the predetermined molding time is reached, stop heating and pressurization, open the mold, and remove the molded silicone product. At this point, silicone products may still have some burrs or excess silicone rubber parts that need to be trimmed. The trimming methods include manual trimming, mechanical cutting, etc. Sometimes it is necessary to perform post vulcanization treatment on silicone products. Post vulcanization can further improve the performance of silicone products, such as enhancing their heat resistance and mechanical strength. Post vulcanization is usually carried out in an oven at a temperature of around 200-250 ℃ for a duration of about 2-4 hours. If silicone products are not post vulcanized and used directly, their performance may decrease over time during subsequent use.   3.Equipment and materials Equipment: The main equipment for hot press forming is a hot press forming machine, commonly known as a flat vulcanizing machine. This machine has two heating plates on top and bottom, which can evenly heat the mold. It is also equipped with a pressure system that can precisely control the pressure applied to the mold. At the same time, the control system can set and adjust parameters such as temperature, pressure, and time to meet different molding requirements. Materials: In addition to silicone rubber raw materials, some auxiliary materials will also be used. For example, release agents can prevent silicone rubber from adhering to the mold, making it easier to remove after molding. Release agents are generally organic silicon or wax substances, which are evenly applied to the surface of the mold during use. In addition, various additives such as crosslinking agents, reinforcing agents, pigments, etc. will be added to improve the performance of silicone rubber. Crosslinking agents are used to promote the vulcanization crosslinking reaction of silicone rubber; Reinforcing agents (such as white carbon black, etc.) can improve the mechanical strength of silicone rubber; Pigments are used to color silicone products. The hot pressing process can produce various complex shaped and high-performance silicone products, which are widely used in electronics, medical, automotive, home and other fields, such as silicone seals, silicone buttons, silicone toys, etc.
