　　There is a thorny problem in the silicone industry, that is, the silicone rubber products suddenly appear whitish and foggy on the surface after a period of use. This phenomenon seems serious, but it can be wiped off after wiping to maintain the original color. , Most of this phenomenon will appear on some products with larger structure and longer curing time. In the industry, this phenomenon is called spit frost and spit fog. Do you have this phenomenon in the silicone products you buy?

　　There are many phenomena that cause whitening of silicone products. Simply put, it is caused by the process error of the silicone product manufacturer or the problem of the formulation in the raw materials. The main reason for the whitening in the raw materials can be judged as silicone oil and other compounds Conflicts occur during the secondary mixing process. For example, if you want to increase the vulcanization time and add appropriate internal mold release to the raw materials, this phenomenon is very common. The mold release agent can improve the mold release rate and production efficiency, but if the dosage is not used correctly, it will cause The product will turn white later!

　　In addition to the wrong method of raw materials and processes, the details of the operation process will also cause whitening to the product. Too much release agent spraying on the production line may lead to the phenomenon of spit frost, which may also occur when the temperature control is uneven. This phenomenon is caused. In addition, there are certain factors for the aging of silicone products. Since the performance of the raw materials is not outstanding, the frequency of whitening is higher due to the influence of the use environment and the temperature difference environment!

　　For the above phenomenon, manufacturers of silicone rubber products should check the parameters of the raw materials before processing, and understand which substances can be added and which substances can not be added. In the final processing, all aspects of the machine need to be remarked. Conditions need to be clarified! The main problem is to control the added substances from the raw materials, such as vulcanizing agent, color glue, silicone oil, etc. It must be figured out whether it can be added and tested after the deployment!
