With the continuous development of food industry technology, the raw materials for the inner and outer packaging of many products are also constantly upgrading. Among them, food grade silicone tubes are also very common in this field. Of course, in the process of understanding a new material, we should also pay attention to its stability and safety.1. Strong high temperature resistanceFor the inner and outer packaging materials of food, high temperature resistance is a very important characteristic, which directly affects the safety of the material. If the high temperature resistance is weak, it is likely to release a certain amount of water that is harmful to health.2. Good transparencyThe permeability of food grade silicone tubing is relatively high. In this way, when making materials and processes, high-tech methods can enhance the adhesion of the sol, thereby utilizing the increased permeability of the product. This can improve the visual effect for consumers.3. No odorNo matter what type of material is used in food, if there is an odor during the production and manufacturing process, it is likely to affect the quality of the product. Therefore, food grade silicone tubing also has this advantage. It does not have any odor, so it will not affect the quality of the product during the manufacturing process, and it is not easy to rot in a sealed environment.Overall, the advantages of food grade silicone tubing are quite obvious. In the process of comparing materials, it can be identified as a high-quality silicone material. Therefore, from this plastic material, it can meet the current human demand for healthy eating and ensure the production of high-quality food.

In the production process of silicone products, the demolding step is the most crucial one. No matter who is involved, they will inevitably encounter problems with difficult demolding. If such problems are severe, they will seriously affect the production efficiency of silicone products. So, how can we solve the problem of difficult demolding? 1. Surface treatment of moldsThe molding mold for silicone products should be cleaned before using the hydraulic molding machine, especially for newly removed molds that must be sandblasted first.Choose different detergents for mold.The sandblasted mold must be heated to a sufficient temperature before mold placement, and the release agent must be sprayed well before molding.It is worth noting that electroplating molds cannot be sandblasted, including resin sand. 2. Spray treatmentIn the molding process of silica gel products, silica gel products do not stick to either side of the mold or the mold spray, but sometimes it is difficult to stick.Solution: Spray bottle or other clean water. If you want the product to stick, after spraying, the product will stick to the place you want to stick. 3. Adjustment of mold temperatureThe product likes to stick to the lower half of the mold temperature. When the upper mold temperature is 175 ℃ and the lower mold temperature is 165 ℃, the product usually sticks to the lower mold when lifting the mold.In short, when silicone products are difficult to demold, do not use better demoulding agents instead of demoulding agents to facilitate drawing, or increase the use and frequency of demoulding agents. Excessive demoulding agents can easily cause dirt on the surface of the mold, which will have a certain impact on the appearance of the product. The use of excessive demoulding agents can also affect the adhesion ability of silk screen printing and injection oil in the later stage. If the above method is not very effective, it can be considered to add an appropriate amount of internal release agent when preparing the material, but it will increase the additional cost of the product.How to quickly demold silicone productsSilicone product factories know that the more modules they can produce in a day, the lower the corresponding cost. The lower the unit price of silicone sleeves, the more obvious the price advantage. Beijite Silicone Products from Silicone Products Factory, as well as the secrets revealed by customers, have these methods for improving the demolding speed of silicone sleeves.After refining raw materials, adding mold release agents and rapid curing agents, the silicone product factory enhances the fluidity of the silicone sleeve. The original 200 second silicone sleeve can shorten the molding time by 30% under the same temperature and pressureThe silicone product factory adjusts the temperature and pressure of the machine. Usually, the higher the temperature, the faster the silicone sleeve is formed. However, excessively high temperatures can also cause explosive edges.Reduce the exhaust frequency of the machine, exhaust the upper and lower molds at a slower speed. If the silicone sleeve is not particularly complex, the exhaust can be reduced twice.Silicone product factories need to work hard on molds and open more discharge tanks to allow the remaining materials to come out. If there are a large number of silicone sleeves, you can choose to open several more holes on the large mold to increase the output of each mold.

With the widespread application of silicone materials, we will see more and more various silicone products in daily life. As a result, people's questions about it will also increase. Recently, many netizens have asked whether silicone products with high hardness will become brittle? The answer is affirmative. What are the specific reasons that can make silicone products brittle? 1. Hardness of silicone products. After silicone products reach a Shore hardness of 60 degrees or above, their tear resistance and elasticity will decrease linearly, leading to the brittleness of silicone products. Most of the silicone products produced by our manufacturers have a hardness below 60 degrees on the Shore hardness scale, except for silicone buttons and some special products requested by customers. 2. Environment and duration of use. During use, if the ambient temperature is too low, the usage time is too long (such as frequent use for several years), and the environment is too humid, it will accelerate the aging rate of silicone products and cause aging phenomena. Brittle is one of its aging phenomena. Especially for silicone products for infants and children, we must clean and disinfect them promptly after use. It should be stored in a ventilated and cool place, avoiding direct sunlight. 3. Some mistakes during the production process. Unreasonable mold design structure can lead to various problems in the production process, such as mold fracturing and brittle finished products. During the processing of silicone products, if the machine temperature is too low, the heating time is too long, and the secondary vulcanization time is too long, it will cause the silicone products to become brittle easily. 4. Silicone material. The inferior silicone material does not meet the performance standards in all aspects. For example, the most basic tear resistance and elasticity properties directly lead to the brittleness of silicone products. So when choosing a manufacturer, we should check their production qualifications and corresponding testing reports for silicone materials.

Silicone rubber O-ring is the most widely used sealing product, and its production process is relatively simple, using a variety of materials. 1.Due to different formulations of silicone rubber O-rings, the tightening and stretching amounts of silicone rubber O-rings produced by different manufacturers are also different. When a product is in a long-term compressed state, there will be a scenario of compressive stress relaxation, which gradually expands over time. The longer the time, the smaller the amount of compression and stretching, resulting in insufficient elasticity and leakage. The most direct method is to increase the cross-sectional size of the product, but it can also lead to an increase in the structural size of the product.2.The correlation between temperature and the relaxation process of silicone rubber O-ring seals. Temperature is very important for the relaxation degree of silicone rubber O-ring seals. Regardless of the rubber material, it will accelerate its aging rate at high temperatures. When the temperature in the environment is higher and the product deformation exceeds 40%, the silicone rubber O-ring will slowly lose its elasticity, leading to leakage. These sealing rings will experience initial stress during the installation of silicone rubber O-ring seals in equipment. They will remain dormant for a long time and gradually relax as the temperature decreases. In some cases, they may dissipate with a sharp drop in temperature. Even if the rubber material is resistant to low temperatures, the stress generated at 20 degrees Celsius will not exceed 25%. Therefore, when setting the initial stress for installing silicone rubber O-ring seals, the factor of working environment temperature should be fully considered. 3.Compared with the above two factors, the influence of medium working pressure on the deformation of silicone rubber O-ring is greater. This is the most common situation that causes deformation of silicone rubber O-ring under various working conditions. With the development of hydraulic equipment, the pressure of hydraulic medium increases. Long term operation of silicone rubber O-ring in this high-pressure environment will lead to irreversible deformation. In this high-pressure environment, the deformation of rubber material will increase with the increase of temperature. The working fluid pressure is an important factor causing permanent deformation of silicone rubber O-ring seals. Therefore, suitable pressure resistant rubber materials should be selected according to the working pressure during design. The greater the homework pressure, the higher the hardness and high pressure resistance of the materials used.

Silicone waterproof sealing ring, as an excellent waterproof and sealing material, has a wide range of application prospects in industry and daily life. However, the length of its service life is directly related to the safety and reliability of the equipment, so it is widely used in the fields of cup lids, pot lids, and other daily necessities. As consumers, how can we ensure the service life of the silicone waterproof sealing ring when using it. Firstly, in terms of material selection, we need to have a certain judgment and understanding of the silicone water cup sealing ring, such as whether its material belongs to ordinary rubber or food grade silicone, and whether the product's softness and hardness are too soft, brittle, or hard.Secondly, regarding its size, the outer diameter of the silicone sealing ring for water bottles is usually slightly larger than the inner diameter to ensure that the sealing ring can be securely installed on the water bottle. The selection of thickness needs to be determined based on the material of the sealing ring, the usage environment, and the sealing requirements. Generally speaking, thicker sealing rings have better sealing performance and durability, but they can also increase the difficulty of installation and disassembly. And in terms of usage, we need to pay more attention to the details of the following aspects!1. The impact of usage environment: The temperature, humidity, pressure, and exposure to corrosive substances in the environment where silicone waterproof sealing rings are located will directly affect their service life.2. Temperature control: The optimal storage temperature for silicone seals is generally between -20 ℃ and+70 ℃. Although silicone has good high temperature resistance and can maintain stability in the temperature range of -60 ° C to+250 ° C, prolonged exposure to high temperatures can still accelerate its aging process. Therefore, it is necessary to avoid exposing the sealing ring to extreme high or low temperature environments to prevent physical changes in its material that may affect its sealing performance. 3. Humidity management: Excessive humidity can accelerate the aging process of silicone gel. Therefore, the storage environment should be kept relatively dry, and desiccants or humidity control devices can be used to control the environmental humidity and ensure that the silicone sealing ring is in suitable storage conditions.4. Light protection, ultraviolet radiation is one of the important factors affecting the aging of silicone gel. Silicone sealing rings should be stored in a dark and cool place, away from direct sunlight, to reduce damage from ultraviolet rays. 5. Although silicone has excellent chemical stability and corrosion resistance, it is still necessary to avoid direct contact with corrosive substances such as strong acids and bases to prevent chemical reactions that may cause damage.6. Frequent opening and closing actions or improper installation methods can cause physical damage to silicone waterproof seals and shorten their service life. Therefore, proper usage and maintenance methods are crucial.7. Reasonable installation: When installing silicone sealing rings, follow the product manual or professional guidance to ensure that the sealing rings are installed in place and avoid poor sealing or damage caused by being too tight or too loose. At the same time, attention should be paid to the direction of the sealing ring. Typically, silicone sealing rings have a flat surface and a protruding annular lip. When installing, it is necessary to ensure that the protruding lip faces the side of the sealing medium to achieve good sealing effect.

The required temperature for silicone buttons is generally controlled between -15 ℃ and+80 ℃, and the storage temperature should also be between -30 ℃ and+85 ℃. The storage time should also be one week. In addition, if the button is not pressed, it needs to be placed flat for long-term storage, but it can only be stored for about a month under compression. The humidity in the working environment should also be maintained between 45% and 95%, the working pressure should be between 86 and 106Kpa, and the contact rebound rate should be less than 12 milliseconds. The insulation resistance of silicone buttons needs to be greater than 1012 ohms/500VDC, and its breakdown voltage is usually greater than 25KV/mm. In addition, from the appearance, we can find that silicone products should be a delicate and uniform paste or present a viscous liquid. The drying time is generally within 10-30 minutes.

We can see that the patterns on silicone screen printing are very beautiful, so there must be someone interested in the process of silicone screen printing. Therefore, the editor will provide a detailed introduction to the silicone screen printing process. Screen printing is the earliest printing method. Screen printing is the abbreviation for "screen printing". Because screen printing requires a mesh board, it is also called screen printing. Generally, silk screen printing ink is thicker and brighter, and the printed patterns have a three-dimensional effect. Screen printing can also print finer lines and is suitable for large-area printing. Screen printing is the process of stretching silk fabrics, synthetic fiber fabrics, or metal wire mesh onto a frame, and using manual coating or photochemical plate making methods to produce screen printing plates. Modern screen printing technology uses photosensitive materials to produce screen printing plates through photographic plate making methods. Screen printing is the process of transferring ink through the mesh holes of graphics and text onto a substrate, forming an image that is identical to the original image. Silk screen silicone is a special type of silicone that is printed through screen printing. Recommendation: Silicone silk screen buttons Now let's talk about how many times do silk screen silicone need to be printed?Silk screen silicone is divided into manual printing and machine printing. Manual printing requires multiple prints to form, but the printing is too slow and the production capacity is not high. Because it is manually scraped, some patterns may have slight ghosting if not careful. Screen printing can only print one color at a time. If color matching is required, first print the first color, then dry it, adjust the position of the screen plate, and then print the second color. And machine printing only takes one time to form. Silk screen silicone has the characteristics of environmental protection, non delamination of printing colors, multiple printing effects, good adhesion, delicate hand feel, excellent performance, non-toxic and harmless. After screen printing, the three-dimensional effect of the product will be enhanced and become more beautiful. Mainly because silk screen silicone is non-toxic and harmless, there is no need to worry about safety issues.

Adhesive foot pads are widely used in various industries as a cushioning effect on product bases. They belong to a type of micro auxiliary accessory with low cost and simple function. However, some products may appear too redundant with them, and some items may not work without them. Therefore, with their functions and functions, many items currently need to use them for cushioning purposes. The difference lies in their different processes and structures. The function of the adhesive foot pad is based on the flat surface that fits the bottom as a whole. Currently, the common adhesive pads are made of flat surface with anti slip texture, and their main processes are the overall rolling process of the flat pad or the molding of the sheet material.This silicone gasket has a wide range of applications and is used in many seats, wardrobes, and electronic products. Therefore, under the premise of flat effect, both sides belong to a flat structure and can be used for adhesive bonding on various flat products. Another type is structural adhesive pads, which must be produced and processed using hydraulic molding technology to create concave convex and curved structures for bonding. This method is mainly used for processing irregular adhesive parts and can be used for customized adhesive parts processing in various fields. Both flat and irregular adhesive parts need to be bonded together, and the adhesive methods are divided into single-sided adhesive and double-sided adhesive. Secondly, adhesive paper is also very important. Currently, commonly used silicone adhesive paper is divided into TPE adhesive paper and double-sided adhesive paper.Adhesive backing paper is also divided into genuine and imitation products, with high strength and conventional viscosity. Different qualities are used in different products. Currently, 3M adhesive backing paper is commonly used for silicone foot pads, so its adhesive paper adhesion and strength should be considered in different foot pad lifetimes.

What is the function of silicone gloves? Silicone gloves are protective equipment made from food grade silicone, and have become an indispensable practical tool in modern kitchens due to their high temperature resistance, anti slip, and easy cleaning properties. From baking trays to hot pot frying, from cleaning utensils to handling frozen ingredients, silicone gloves provide comprehensive safety protection for chefs through physical protection and functional design. Its application scenarios cover home kitchens, baking studios, and the catering industry, becoming a key equipment for improving cooking efficiency and safety. 1. Core function: High temperature resistance and thermal insulation protectionThe core advantage of silicone gloves lies in their excellent high-temperature resistance. High quality silicone material can withstand extreme temperatures ranging from -40 ℃ to 250 ℃, effectively blocking heat transfer and preventing hand burns whether removing a 200 ℃ baking tray from the oven or handling a freshly cooked hot soup pot. Some products are further enhanced in insulation effect through thickened design or double-layer silicone structure, ensuring safety during long-term operation. For example, in baking scenarios, silicone gloves can safely lift high-temperature cake molds, avoiding the risk of burns caused by direct contact with metal molds. 2. Anti slip design and operational stabilityIn kitchen operations, oil and water stains often cause tableware to slip off, and silicone gloves solve this problem through surface texture design. The surface of the gloves adopts honeycomb shaped protrusions or wavy patterns to increase friction, even if the hands are stained with oil or water, they can still firmly grip heavy objects such as hot pots and soup bowls. This anti slip performance is particularly important in scenarios such as stir frying and holding hot soup, which can significantly reduce the risk of burns or breakage caused by slipping. In addition, some products are designed with finger and finger styles for different operational needs: finger styles have high flexibility and are suitable for fine operation; The connected finger style has strong wrapping ability and is suitable for grasping large appliances. 3. Easy to clean and hygienic safetyThe non oleophilic properties of silicone material give it the advantage of "self-cleaning". Oil stains and food residues are difficult to adhere to the surface of gloves. After use, simply rinse with water or mix with a small amount of neutral detergent to quickly restore cleanliness. This feature not only simplifies the cleaning process, but also avoids the problem of bacterial growth caused by oil and water absorption in traditional cotton gloves. For cooking scenarios that require frequent contact with raw meat, the ease of cleaning of silicone gloves can effectively reduce the risk of cross contamination. In addition, food grade silicone material has passed international safety certification, is non-toxic and odorless, and will not release harmful substances even when heated at high temperatures, ensuring safety in contact with food. 4. Multi functional scene adaptabilityThe application scenarios of silicone gloves far exceed basic protection requirements, and their versatility is reflected in the following aspects:Low temperature protection: When handling frozen ingredients, silicone gloves can isolate low temperatures, avoid hand frostbite, and maintain operational flexibility.Cleaning assistance: When used with cleaning agents, silicone gloves can protect the skin of the hands from chemical irritation, and their non slip surface can also improve wiping efficiency.Children's cooking assistance: Thick silicone gloves can provide safety protection for children, reduce the risk of burns during cooking, and cultivate hands-on skills.Outdoor Barbecue: In outdoor barbecue scenes, silicone gloves can resist the high temperature of charcoal fire and meet the anti slip requirements of open environments.Some products have further expanded their functional boundaries through innovative design, such as integrating magnetic hooks for easy storage, or adopting detachable finger cots to meet different operational needs.
