The silicone products that many people in the silicone market respond to will produce a smell or even a pungent odor, mainly because of the use of various additives in the production of silicone products, which are generated by the response of promoters and vulcanization. So some silicone product producers are going to choose the right additives for this, or, according to the product of the odors, to add the appropriate chemical agent to react.
Most manufacturers will choose the essence, the detergent, the deodorant, the adsorbant, and even the combustion method; But these additives are not to taste, but to cover up the taste; The deodorant of the essence is not a protective agent for concealment, and there are two disadvantages to applying it:
This will produce new pungent smells;
The smell will rebound, and over time the fragrance of the fragrance will be evaporated, the smell of the auxiliary will be hidden, the bad smell will come out.
Therefore, to really remove the smell of silica gel, the method is to optimize the selection of silicone raw materials and the process of vulcanization.
The processing of silicone raw materials and production: often some silicone manufacturers will increase the amount of the natural oil that is bound by the amount of money that the money increases. However, these will have to be used in the environment of environmental protection and the ability to operate oil with the ability to resist and degrade the polluting volatile volatile things in rubber. So we want to deal with the smell of silicone products on the bottom from the material and the production of the silica gel.
For example, the oil is selected for a high, odorless; Do not increase the amount of gum. Do not use the accelerator cbs; Don’t use DCP and so on.
2. Vulcanization system and process: silica gel for gas phase glue, add odorless vulcanizing agent rubber, silica gel molding through secondary vulcanization (secondary vulcanization time is recommended to be more than 4 hours, the temperature is about 200 degrees, and for the vacuum oven.)
