   What should pay attention to during the vulcanization process of silicone products

  In the whole process of silicone vulcanized rubber, it is necessary to select the appropriate production temperature and vulcanized rubber time according to different types of vulcanization accelerators; typical metal catalysts used for silica gel vulcanization are double-two five, double two-four (peroxide), platinum vulcanization Three kinds of accelerators. Appropriate solid silica gel is formed under the catalyzed reaction of the double five vulcanization accelerator at a high temperature of 170°C. Among them are pure silica gel, metal materials such as pure silica gel, PRIMER primer super glue brushed with CL-24, tempered laminated glass, polyester, porcelain, bakelite and other compression molded products. It must be noted that the recommended time for secondary vulcanization of rubber should not exceed 200°C and the time should be within two hours. Typical silicone kitchen supplies (silicone spoon, spatula, fruit salad bowl, egg beater, yellow butter scraper, etc.), cable accessories (composite insulators, lightning arresters), miscellaneous pieces. At 120℃ ultra-low temperature, it is a solid rubber compound of bis-two-four vulcanized rubber or a liquid silica gel of platinum vulcanization accelerator. It is made of metal material and PC/PBT/PA polyester plastic material that have been brushed with CL-26AB glue. Among them, the previous one must be secondary vulcanized rubber processing technology proposed to be less than 180 ℃ within 2 hours. Among them, pregnant and infant silicone glass bottles, medical urine tubes, balloons, mobile phone cases, diving glasses, smart phone moisture-proof parts (SIM card holder, type-c, USB interface, FPCBpcb circuit board moisture-proof, microphones, earphones, audio speakers , Rechargeable battery cover, moisture-proof, etc.)

In the whole process of silicone vulcanized rubber, comprehensive factors such as mold release, maturation, machinery and equipment should also be considered. In order to better prevent poor products, it is recommended that after adjusting the various main parameters of the sample, in mass production, the silicone product manufacturer can have a better pass rate for different products, and improve productivity and market competitiveness.

   In the whole process of vulcanization of silicone products, the staff reduced the time of vulcanized rubber to better increase the production volume and increase the efficiency of production and manufacturing. As a result, the products that are out of the mold will appear soft. In order to increase the production volume while reducing the time, the staff must increase it. The temperature is at a certain equilibrium rate, otherwise the product will have various safety hazards, and the production time is too long, and the product will be too brittle and tearing. It is recommended that the product be properly manipulated during the processing process. Time and temperature of vulcanized rubber. Except for equipment, raw materials, human factors, natural environment and other factors in the processing of silicone products, silicone products are not prone to product quality problems.
