Firstly, we know that desiccants need to play a role in moisture and mold prevention, so the material must be able to achieve high adsorption strength, have certain advantages in acid-base reactions, slow aging rate, insolubility, and strong chemical stability. Only then can it be stored for a long time. Silicone material is a highly active adsorbent material that cannot tolerate any substances and has strong adsorption capacity. It mainly absorbs water vapor through adsorption, and silicone material has strong stability, and long-term storage will not cause any aging or depletion, so its effectiveness and lifespan as a desiccant are completely stable. During the service life of silica gel desiccant, experimental methods can be used. If stored in a dry and liquid free environment for a long time, it will have a certain moisture-proof and mildew proof effect. If used in environments with high humidity and severe ozone, the service life will be reduced. In the case of water seepage, it takes about a year, but without water seepage, it can be used for a long time. Its lifespan is entirely determined by the environment, but it can be used for a long time after normal storage. The use of desiccants is very extensive in the industry, and this auxiliary material has also made desiccant materials a production conversion category in the manufacturing industry. Desiccant materials can also be divided into many types. At present, there are mineral desiccants, fiber desiccants, quicklime materials, montmorillonite desiccants, activated alumina and silica gel desiccants, etc. Nowadays, silicone desiccants are commonly used as static items, and no one will move them casually, so they can still achieve good results in moisture and mold prevention!

How to distinguish the quality of silicone sealing rings? As an indispensable sealing component in modern industry and daily life, the performance of silicone sealing rings directly affects the sealing effect and service life of products. However, the quality of silicone seals on the market varies greatly, and how to accurately distinguish their advantages and disadvantages has become a challenge for consumers and procurement personnel. Today, we will take you to understand how to distinguish the advantages and disadvantages of silicone seals.   1. Appearance inspection: Comparison between fine and rough The appearance of silicone sealing rings is the first threshold for their quality. Authentic silicone sealing rings usually have a fine appearance, smooth edges, no obvious defects, uniform color, and soft texture. This is because high-quality silicone materials undergo fine processing during the manufacturing process, ensuring the appearance and texture of the product. In contrast, inferior silicone seals often have a rough appearance and may have issues such as bubbles, dents, color differences, etc. These defects not only affect the aesthetic appearance of the product, but may also imply defects in its internal structure, thereby affecting the sealing effect and service life. 2. Odor identification: comparison between odorless and pungent Odor is another important criterion for judging the quality of silicone sealing rings. Authentic silicone seals usually have no odor or a faint silicone smell, because high-quality silicone materials are non-toxic and odorless, and harmless to the human body. Poor quality silicone seals may emit a pungent odor due to the presence of inferior materials or additives. These harmful substances may not only pose a threat to human health, but also affect the performance and lifespan of silicone seals. 3. Elasticity Test: Comparison of Resilience and Deformation Elasticity is one of the important performance indicators of silicone sealing rings. Authentic silicone sealing rings have good elasticity, can be easily bent and stretched, and have strong restoring force, which can quickly restore their original state after being subjected to external forces. This excellent elasticity ensures the sealing effect of silicone sealing rings in various complex environments. However, inferior silicone seals have poor elasticity, are prone to deformation, and have weak resilience. After being subjected to external forces, these sealing rings may not be able to fully restore their original state, resulting in a decrease in sealing effectiveness or even failure. 4. Evaluation of heat and cold resistance: performance under extreme temperatures The use environment of silicone sealing rings often involves extreme conditions such as high or low temperatures. Therefore, its heat and cold resistance is also an important criterion for judging its quality. Authentic silicone sealing rings have excellent heat and cold resistance, and can be used for a long time in the temperature range of -60 ℃ to+200 ℃ without deformation or harmful substances. This excellent performance ensures the stability and reliability of silicone seals in various harsh environments. In contrast, inferior silicone seals often perform poorly at extreme temperatures. They may soften or deform at high temperatures, or harden or become brittle at low temperatures, thereby losing their sealing effect. 5. Environmental performance considerations: non-toxic and harmless guarantee With the increasing awareness of environmental protection, the environmental performance of silicone sealing rings has become a focus of consumer attention. Authentic silicone sealing rings are made of environmentally friendly materials, non-toxic and harmless, and comply with relevant environmental standards and regulatory requirements. Poor quality silicone seals may contain harmful substances such as heavy metals, plasticizers, etc. These substances may be released into the environment during use, posing a potential threat to human health and the environment. 6. Brand and channel selection: guarantee of reputation and quality In addition to the direct judgment in the above aspects, the choice of brand and channel is also an important factor in distinguishing the quality of silicone seals. Famous brands usually have a sound quality management system and after-sales service system, which can ensure the quality and performance of their products. Meanwhile, choosing legitimate channels to purchase silicone sealing rings is also the key to ensuring quality. Legitimate channels usually provide authentic product information and quality assurance, avoiding consumers from purchasing counterfeit and inferior products.   Distinguishing the quality of silicone seals requires comprehensive consideration from multiple dimensions. Through methods such as visual inspection, odor identification, elasticity testing, heat and cold resistance evaluation, and environmental performance considerations, we can effectively screen out high-quality silicone sealing ring products.

What are the technical requirements for the production of silicone parts? Silicone parts have been widely used in many fields due to their excellent weather resistance, corrosion resistance, and electrical insulation performance. However, the production of silicone parts is not easy, as it requires strict technical requirements and precise process control. From raw material selection to molding process, to post-treatment and quality inspection, every step is crucial.   The main material of silicone parts is silicone rubber, which is a highly active and stable material. When manufacturing silicone parts, it is necessary to choose high-purity silicone rubber as raw material to ensure the performance and stability of the parts. In addition, it is necessary to select appropriate fillers, plasticizers, and other additives based on specific application scenarios and performance requirements to meet the specific performance requirements of the parts. The types and proportions of these additives have a significant impact on the physical, chemical, and processing properties of silicone parts.   In the production process of silicone parts, dimensional accuracy is an important technical indicator. The dimensional accuracy of silicone parts directly affects their fitting accuracy and stability with other components. Therefore, in the manufacturing process, it is necessary to strictly control the dimensional accuracy of the parts to ensure that they meet the design requirements. Generally speaking, the dimensional accuracy of silicone parts should be controlled within ± 0.1mm, which requires the use of high-precision molds and precise molding processes to achieve.   In addition to dimensional accuracy, the surface quality of silicone parts is also crucial. During the manufacturing process, it is necessary to ensure that the surface of the parts is smooth, free of defects such as flaws and bubbles. The quality of the surface not only affects the appearance of the parts, but also directly affects their service life and performance. Therefore, in the manufacturing process, it is necessary to perform strict surface treatment on the parts, such as spraying, electroplating, etc., to improve their corrosion resistance and wear resistance.   Mechanical properties are another important technical indicator of silicone parts. Silicone parts need to have certain mechanical properties such as tensile strength, tear strength, and compression permanent deformation, which directly affect the service life and stability of the parts. In the manufacturing process, it is necessary to select appropriate formulas and process conditions to ensure that the mechanical properties of the parts meet the design requirements. This requires in-depth research and optimization of the formula for silicone rubber to ensure that the parts can maintain good mechanical properties even in harsh environments.   Weather resistance is another key technical requirement for silicone parts. Silicone parts need to have certain weather resistance, corrosion resistance, aging resistance and other properties to adapt to various harsh environmental conditions. During the manufacturing process, it is necessary to select appropriate fillers and additives to improve the weather resistance of the parts. At the same time, it is necessary to conduct strict weather resistance tests on the parts to ensure that they can maintain good performance and stability during use.   Environmental performance is increasingly being emphasized in the production of silicone parts. With the continuous improvement of environmental awareness, the environmental performance of silicone parts has become one of the important technical indicators. In the manufacturing process, it is necessary to choose environmentally friendly raw materials and additives to reduce the impact on the environment. At the same time, it is necessary to effectively treat and recycle the waste generated during the production process to reduce its impact on the environment.   In the production process of silicone parts, compression molding, extrusion molding, injection molding, and drip molding are commonly used processes. Compression molding is the process of placing mixed silicone raw materials into a mold and vulcanizing them through heating and pressure. This process has the advantages of high production efficiency, high product size accuracy, and suitability for large-scale production. However, the disadvantages of high mold costs and limited product shapes cannot be ignored.   Extrusion molding is the process of extruding silicone raw materials into the desired shape using an extruder, and then producing products through processes such as cooling and cutting. This process has the advantages of high production efficiency, regular product shape, and suitability for continuous production. However, the disadvantages of relatively low product size accuracy and high mold costs also need to be considered.   Injection molding is the process of injecting silicone raw materials into a mold using an injection molding machine, and then shaping it through heating and cooling. This process has the advantages of high production efficiency, high product size accuracy, and suitability for large-scale production. However, the high cost of molds and large equipment investment also limit its application scope.   Dropping molding is a handmade process for making silicone products, which involves dropping silicone raw materials into molds and then shaping them through heating and curing. This process has the advantages of simple operation, low cost, and suitability for small-scale production. However, its low production efficiency and relatively low product size accuracy also limit its application range.   Quality inspection is also a crucial step in the production process of silicone parts. Strict quality inspection is required for raw materials to ensure their performance meets production requirements. At the same time, it is necessary to strictly control and manage the quality of each link in the production process to ensure that the silicone parts produced meet the design requirements and relevant standards. This includes comprehensive monitoring and testing of the accuracy of the mold, the stability of the molding process, and the quality of post-processing.   The production of silicone parts requires strict technical requirements and precise process control. From raw material selection to molding process, to post-treatment and quality inspection, every step is crucial.

Whether a silicone spoon is good or not, when a shiny stainless steel spoon leaves its first irreparable white mark in a carefully selected expensive non stick pan, every pot lover deeply understands the heartache of that moment. It was this excruciating pain that finally made me turn my attention to the new silicone member in the kitchen. They are brightly colored and have a soft texture, claiming to perfectly protect the coating of every beloved pot. However, beneath that gentle touch, can their practicality really replace the harder traditional mainstay in the kitchen? I began to try with cautious curiosity. If you have also been troubled by the fear of scratches on cookware, why not follow me to explore and today we will take you to understand whether silicone spoons are good or not.   The core value of silicone spoons undoubtedly lies in their unparalleled caring power. Its soft material is like putting an invisible protective garment on delicate cookware. Faced with the precious PTFE coated frying pan at home, I can finally stir fry dishes without worrying about the harsh metal scraping sound, as evidenced by the smooth walls of the pan. This sense of security makes every cooking experience easier and more enjoyable.   The silicone spoon is not only soft, but also demonstrates an excellent balance between toughness and temperature resistance. Its material maintains good toughness and stability in a wide temperature range of -40 ℃ to 230 ℃, which is sufficient to meet the needs of various kitchen challenges such as frying, stir frying, boiling, and serving. Whether it's hot soup just out of the heat or cold and hard ice cream taken out of the freezer, the silicone spoon can easily handle it. I particularly value its performance when stir fried in hot oil at high temperatures - the spoon body does not soften or curl, nor does it release any worrying odors, making it safe to use. Compared to wooden spoons that are prone to cracking and hiding dirt, and metal spoons that are abrupt and hot to the touch, silicone spoons do provide us with a reassuring and worry free new experience.   Improving cleaning efficiency is also a practical bonus. The smooth and non absorbent surface of the spoon means that food residue is not easily adsorbed, and the cleaning process is almost "one touch clean" - even some spoons naturally slide off stains under the rinsing water flow, saving the trouble of back and forth wiping. It does not absorb oil or water, and there will be no residual odor. Cleaning it in the dishwasher is also efficient and effortless.   Silicone spoons are not perfect either. Its relatively soft spoon head and edges are slightly less efficient than hard metal spatulas when dealing with extremely hard, frozen solidified whole pieces of butter or deeply shoveling tightly charred pots. If pursuing a perfect cutting feel, stainless steel tools are irreplaceable at this time. At the same time, attention should be paid to avoiding long-term contact with sharp objects such as knife tips to prevent accidental cutting and damage.   Overall experience shows that silicone spoons undoubtedly occupy a special high-value position in the kitchenware family. Its soft and invisible hands carefully protect every inch of the precious cookware coating; With its strong temperature adaptability and excellent easy to clean characteristics, it has become a reassuring companion in daily cooking. Although limited in extreme durability and cutting scenarios, it cleverly fills the gap that traditional material kitchenware cannot balance.   There is no tool in the kitchen that can monopolize all advantages. But when both care and practicality are achieved, silicone spoons become a new choice worth investing in. After all, every pot is worth treating gently, and every leisurely cleaning is a small happiness when cooking.

Everyone knows that silicone products are no longer as monotonous as before. Many accessories in the market, kitchen supplies in daily life, household items, and so on have different colors. However, many purchasing friends have doubts about the colorful silicone products, fearing that their color quality may have various problems. But for friends who are not very familiar with silicone products, do you know how silicone products are colored?   Silicone raw materials are originally transparent in color, colorless and odorless. They are a highly active material with strong adsorption properties and do not conflict with any substances except for strong alkalis. However, due to the need to maintain various styles of silicone raw materials during the production process, there are many choices available. Therefore, silicone product manufacturers use colorants to add various colors to it to maintain its appearance. Silicone colorants are formed by the aggregation of silicone raw materials, silicone oil, color powder, and dispersants. Therefore, choosing to use silicone colorants to produce the color of silicone products is because of their stable performance, high dispersibility, uniform use on products, environmental protection, non toxicity, non pollution, long-term storage, and will not expire. Many characteristics are similar to those of silicone raw materials. It can also be divided into many types, mainly organic colorants and inorganic colorants.   Silicone color masterbatch is an indispensable item for silicone product manufacturers. Its main process is used in the rubber mixing process. If no color masterbatch is added during the rubber mixing process, the mixed rubber will be transparent color. After molding and vulcanization, transparent silicone products will be obtained. The color of silicone masterbatch needs to be carefully adjusted to achieve good results, which is also an important technical task for silicone manufacturers. The color can reach thousands of different colors, and many products with little color difference are the most difficult to adjust. And when it is made with silicone raw materials, it is distributed according to the corresponding proportion and combined with vulcanizing agents to obtain the raw materials for making products. The performance selection of color masterbatch also affects the performance of a product. The common reason for color change in silicone products also has certain reasons in the selection of color masterbatch. The choice of light resistance performance, strong light resistance can achieve no color change effect, generally divided into eight levels! Heat resistance, the better its heat resistance, the higher its dispersibility. A high dispersibility means that the color distribution of the product is uniform, so it can be chosen in any way.

What is laser engraving technology? How to apply it in the silicone rubber products industry? Many people may not understand it very well! Laser engraving or laser marking, laser engraving is a surface treatment process similar to mesh transfer printing, which involves printing characters or patterns on products. Laser engraving, also known as laser engraving, is a process that uses optical principles for surface treatment. It is commonly used for buttons on mobile phones and electronic dictionaries. Make permanent marks on the surface of a substance or inside a transparent substance using a laser beam. Laser has two types of effects on matter: chemical and physical effects. When a substance absorbs laser in an instant, a physical or chemical reaction occurs, resulting in the engraving or display of patterns or text. Therefore, it is also known as a laser marking machine or laser engraving machine!

For consumers who are not familiar with silicone materials, the physical hardness of silicone rubber products may cause great inconvenience. The same product size will not have much variation, and the relationship between material formulation and various physical properties is not fully understood, which can lead to many functional impacts on assembly. Various raw materials such as silicone and rubber have their own hardness and flexibility characteristics, and silicone rubber products are no exception. So why silicone materials can be used in various industries is because they have different soft and hard supports!   Different silicone products have their unique properties and process requirements. For example, silicone seals, silicone accessories, etc., the most suitable polymer and combination can be selected and reasonably adjusted to achieve a tight fit of softness and hardness. Sealing, shock absorption, waterproofing, oil resistance, etc. The physical properties of softness and hardness are closely related to the formula and raw materials of the product. The debugging of formulas can test various performance differences and functions, so it is still necessary to debug the softness and hardness, otherwise the error in softness and hardness may inevitably cause trouble! Everyone knows that silicone materials have good tensile strength, and the indicator of tensile strength depends on the softness and hardness of the product. The general softness and hardness of silicone rubber product manufacturers are around 20-80 degrees. The lower the hardness, the better the product. The tensile strength is good, generally reaching around 300%, with the lowest being around 20%. However, the tensile strength still depends on the structure and shape of the product.   What silicone materials cannot do without is tear strength. Silicone rubber materials can tear due to stress factors. This is one of the inevitable phenomena in all soft colloidal materials, where cracks and fissures can cause damage due to stress. It accounts for a minority because normal hardness silicone rubber generally does not tear or break. Materials with higher hardness are prone to tearing due to crack propagation! Therefore, the tensile strength and hardness of silicone products are important indicators of the material. In the vulcanization production process of silicone processing manufacturers, the larger the silicon molecular weight of the mixed rubber, the greater the effective cross-linking elongation stress. In order to obtain the specified tensile stress, for materials with smaller molecular weights, the crosslinking density can be appropriately increased. Any structural factor that can increase intermolecular forces. Increasing the density of silicone material can prevent the hardness of the product from affecting its tensile strength!

Sealing plugs are usually made of silicone rubber soft gel, and many common items in daily life cannot do without the assistance of silicone sealing plugs. Whether its functionality can meet the sealing performance of the product body and the long-term service life performance depends on whether its quality can meet your usage performance!   The function of silicone sealing plugs mainly includes several sealing forms for mouth sealing, such as conical inner buckle sealing type, outer sleeve buckle sealing type, internal reverse buckle sealing, thread twist sealing, I-shaped concave convex sealing, etc. Each sealing effect depends on the main structure of the product. In addition to the structure, it is necessary to understand several basic points to determine its sealing effect and use digital technology. 1. The material factor plays a significant role. Firstly, the performance of the material affects its tensile rebound deformation rate. Due to different formulations and the formulation of silicone source manufacturers, the properties of the raw materials used are different. Silicone materials also have specific properties, such as which material is suitable for functional seals and which is suitable for appearance parts, which have certain differences. So the selection of materials must have specific formula properties. Secondly, the hardness of the material is crucial, and different levels of softness and hardness are one of the main issues that lead to the sealing assembly of silicone plugs. For example, 30 degrees and 80 degrees are two different concepts. Their difference lies in the fact that 30 degrees of softness can be used for better airtightness and liquid sealing performance, while 80 degrees of high hardness can better cushion stress performance. Therefore, both types of hardness have their own advantages and are used in different ways for mechanical equipment and household sealing.   2. The softness and hardness caused by processing are different, and sealing plugs can easily lead to two different phenomena during the production process. During the production process, due to the increase in production and the acceleration of vulcanization speed, the product may become soft and partially immature, resulting in assembly softening. Secondly, the processing time is too long and the mold cannot be released in time, resulting in long-term high-temperature curing and brittleness.   3. Whether the structure of the design is reasonable, as silicone belongs to soft colloids, if used for a long time, there is no certain interference difference in the design. Long term friction can easily cause the sealing plug to fall off and loosen. Therefore, in the design, it is necessary to grasp the size of the silicone sealing plug as much as possible, and at the same time adjust the soft hardness with the size. When increasing the hardness, the interference amount needs to be reduced, and when the hardness decreases, the interference amount must be increased to ensure the tightness of the plug. To ensure the sealing performance of the sealing plug, the above methods can be used as a reference for general methods. However, for some special sealing plugs, it is recommended to adjust them before conducting sample experiments to ensure their safety performance before mass production.
