How to deal with yellowing of silicone products? Silicone products are widely used in daily life and industrial production due to their softness, durability, and environmental friendliness, such as silicone phone cases, kitchen supplies, medical accessories, etc. However, many users have found that silicone products may turn yellow after a period of use, especially transparent or light colored silicone products. This not only affects aesthetics, but may also raise concerns about its safety. So, why do silicone products turn yellow? How to effectively handle it?   Reasons for yellowing of silicone products 1. Oxidation reaction The silicon oxygen bond (Si-O) in silicone gel is prone to oxidation reaction when exposed to air, high temperature, or ultraviolet radiation for a long time, generating chromophores (such as carbonyl groups) and causing the surface to turn yellow. 2. Ultraviolet irradiation Ultraviolet radiation is one of the main factors causing the aging of silicone gel. Long term exposure to sunlight can cause changes in the molecular structure of silicone gel, accelerating yellowing. 3. Environmental pollution Dust, oil fumes, nitrogen oxides (NOx) and other pollutants in the air adhere to the surface of silicone gel, and long-term accumulation can lead to yellowing. 4. Contact with chemical substances If silicone products come into contact with strong acids, strong alkalis, or certain cleaning agents (such as bleach, disinfectant), they may undergo chemical reactions, resulting in surface discoloration. 5. Material issues Low quality silicone may contain impurities (such as iron ions) or incompletely polymerized monomers, which are more prone to oxidation and yellowing.   The treatment method for yellowing of silicone products 1. Home cleaning and restoration plan Suitable for silicone products with slight yellowing, simple operation and low cost: Toothpaste wiping: Apply white toothpaste to the yellowing area, gently wipe with a soft cloth, and then rinse with water. Baking soda paste: Mix baking soda with warm water in a ratio of 1:3, apply to the yellowed area and let it sit for 2 hours before brushing. Hydrogen peroxide soaking: Soaking in 3% concentration hydrogen peroxide for 6-8 hours can decompose deep pigments (suitable for white silica gel). Citric acid scrubbing: A 10% citric acid solution combined with a nano sponge is suitable for wiping oily yellow spots. White vinegar soaking: Mix white vinegar with water at a ratio of 1:2 and soak for 15-30 minutes to reduce yellowing. 2. Chemical methods for removing yellowing Suitable for stubborn yellowing, but should be handled with caution: Bleach treatment: Dilute bleach and soak (only for white silicone), pay attention to concentration and time. Alcohol wiping: Medical grade alcohol can remove some stains and yellowing, but it may affect the elasticity of silicone. 3. Professional renovation technology Suitable for valuable silicone products (such as high-end headphone covers, medical accessories): Ozone fumigation: Professional equipment decomposes pigment molecules to restore transparency. Plasma cleaning: High energy particles bombard the surface to thoroughly remove the oxide layer. Nano titanium dioxide coating: forming a protective layer to delay yellowing.

Nowadays, new environmentally friendly materials are one of the important basic industries for the development of the national green economy. They not only provide us with various practical problems, but also solve many inconveniences in our daily lives.

However, in addition to this, it still has many advantages.   Customized processing of silicone miscellaneous parts can achieve diversified and unique designs, and products can be designed without imitation, while achieving functional effects. In addition, compared with other materials, silicone raw materials can replace various materials such as rubber, plastic, etc., which are safe, non-toxic, and environmentally friendly. Silicone products have strong advantages in terms of tensile strength, tear resistance, and resistance to high and low temperatures. Simultaneously unaffected by environmental climate change. Its core advantage lies in the fact that it belongs to organic polymer elastomers, and silicon chains do not react or conflict with any substance, do not disperse, concentrate, evaporate, or melt water. Silicon molecules combine with each other to form a certain molecular chain body, thereby achieving advantages such as tensile rebound, temperature resistance, and aging resistance.   Silicone miscellaneous products can be customized and processed according to the customer's appearance design and functional requirements, such as the required hardness, sealing degree, appearance, and decorative effect of the product. After assembly, if the silicone miscellaneous parts cannot meet the usage requirements, they can be adjusted and repaired according to the customer's ideas and design. If the product needs to be glued, it can be repaired. However, if the product involves reducing the amount of glue, it can be more complicated. Therefore, customers need to carefully understand the material and process of silicone rubber products when designing drawings. Of course, the design drawings can also be entrusted to us to complete, and we can provide targeted solutions to the customer's product design and functionality from a professional perspective.

In order to improve the cold resistance of rubber materials, researchers have adopted various methods. These methods mainly include rubber copolymerization and chemical modification, rubber blending, addition of plasticizers, rational selection of vulcanization and filling systems, etc. 1. Rubber copolymerization and chemical modification Rubber copolymerization and chemical modification are effective methods to improve the cold resistance of rubber materials. By introducing monomers with large side groups for copolymerization, the regularity of rubber molecular chains can be disrupted, and their Tg and Tb can be reduced. For example, introducing monomers with flexible structures into fluororubber molecules can increase the flexibility of the molecular chains, reduce intermolecular forces, and thus improve the cold resistance of fluororubber. In addition, chemical modification methods such as epoxidation and isomerization can be used to alter the structure of rubber molecular chains and improve their cold resistance. Rubber blending is a common method to adjust cold resistance in rubber formula design. By combining different types of rubber, their respective advantages can be comprehensively utilized to improve the cold resistance of rubber materials. For example, combining styrene butadiene rubber (SBR) with butadiene rubber (BR) can improve the cold resistance of the rubber. This is because SBR and BR have lower Tg and good molecular chain flexibility, and can still maintain a certain degree of elasticity at low temperatures. Adding plasticizers is one of the effective measures to improve the cold resistance of rubber materials. Plasticizers can increase the flexibility of rubber molecular chains, reduce intermolecular forces, and make molecular segments easier to move. At low temperatures, plasticizers can act as lubricants, reducing friction and resistance between rubber molecular chains, thereby improving the cold resistance of rubber. Common plasticizers include petroleum based hydrocarbon solvent plasticizers and non solvent plasticizers.

What are the details of silicone product processing technology? Silicone products are widely used in medical, baby products, kitchen utensils, electronic products and other fields due to their environmental protection, durability, high and low temperature resistance and other characteristics. However, the processing technology of silicone products is complex, involving multiple links and details. 1. Raw material preparation and quality control The processing of silicone products begins with the preparation of raw materials. The main raw materials include silicone rubber, vulcanizing agents, fillers (such as white carbon black and silicone oil), plasticizers, coloring agents, etc. Among them, silicone raw rubber needs to have the characteristics of high purity and low impurities to ensure the biocompatibility and stability of the product. Vulcanizing agents are key substances that promote crosslinking of silicone gel, and their types and amounts directly affect the physical and chemical properties of the product. In terms of raw material storage, the principles of dryness, coolness, and ventilation should be followed, avoiding direct sunlight and high temperature environments to prevent material aging or performance degradation. In addition, batch management of raw materials is crucial to ensure stable quality of each batch and avoid product performance fluctuations caused by material differences. 2. Mixing process: the key to uniformity and stability Mixing is the process of uniformly mixing silicone rubber, vulcanizing agents, fillers, etc. in proportion. This step requires strict control of temperature, time, and stirring speed to prevent premature vulcanization caused by high temperature or uneven mixing caused by low temperature. Specifically, the mixing temperature is usually controlled within a certain range, and the specific value needs to be adjusted according to the material properties. The stirring speed should be moderate to ensure that the materials are thoroughly mixed and no bubbles are generated. After the mixing is completed, the quality of the mixed rubber needs to be tested, including indicators such as hardness and tensile strength, to ensure that it meets the requirements for subsequent processing. 3. Molding process: shaping of shape and performance There are various molding processes for silicone products, including compression molding, injection molding, extrusion molding, rolling molding, and injection molding. Compression molding: suitable for products with complex shapes and precise size requirements. By applying pressure through high-temperature molds and vulcanization machines, the silicone raw material is vulcanized into shape. This process requires strict control of mold temperature, pressure, and time to ensure product dimensional accuracy and surface quality. Injection molding: Combining the characteristics of liquid silicone and plastic, suitable for products with high quality requirements. Its products have excellent thermal stability, cold resistance, and electrical insulation properties, and are widely used in medical, infant products, and other fields. Extrusion molding: suitable for producing long or tubular products, such as silicone hoses, sealing strips, etc. During the extrusion process, it is necessary to control the extrusion speed and temperature to ensure stable product shape and uniform size. Rolling forming: used for producing larger products such as silicone sheets and silicone sheets. By using a rolling mill to press the mixed rubber into a predetermined shape and thickness, attention should be paid to the effects of rolling temperature, pressure, and speed on product performance. Injection molding: suitable for products with simple shapes and smooth surfaces. By pouring liquid silicone into the mold and allowing it to dry and form, the product can be removed. This process is labor-saving and time-saving, but attention should be paid to the accuracy of the mold and the design of the demolding slope. 4. Sulfurization process: Formation of cross-linked structure Sulfurization is a key step in the processing of silicone products, which forms cross-linked structures between silicone molecular chains through vulcanization, thereby improving the strength and stability of the products. The vulcanization temperature, time, and pressure need to be adjusted according to the specific requirements of the product. During the vulcanization process, it is necessary to closely monitor the operating status and vulcanization effect of the vulcanizing machine to avoid performance problems caused by insufficient or excessive vulcanization. Insufficient vulcanization can lead to low hardness and poor strength of the product; Excessive sulfurization may make the product brittle and prone to cracking. 5. Post processing and inspection: the ultimate guarantee of quality After molding, silicone products need to undergo post-processing, including trimming, deburring, cleaning, and other steps. Trimming mainly involves removing excess scraps and burrs; Cleaning is the process of removing stains and impurities from the surface of a product. During the post-processing process, attention should be paid to operational skills and safety to avoid damage or contamination to the product. Inspection is an important step in ensuring the quality of silicone products. The inspection covers multiple aspects such as appearance quality, dimensional accuracy, physical properties, chemical properties, etc. Only products that have undergone strict quality inspection and meet standard requirements can be sold after leaving the factory. 6. Safety production and environmental protection: the cornerstone of sustainable development In the processing of silicone products, safety production and environmental protection cannot be ignored. Strict adherence to safety operating procedures is required to ensure the safety of employees and equipment. At the same time, pollutants such as exhaust gas and wastewater generated during the processing need to be effectively treated to reduce their impact on the environment. The processing technology of silicone products involves multiple links and details, and each link requires strict control of quality and technical parameters. Only through precise processing techniques and strict quality management can high-quality silicone products that meet market demand be produced. With the continuous advancement of technology and the continuous development of the market, the field of silicone product processing will usher in more opportunities and challenges.

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.

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.
