With the continuous improvement of liquid silica gel products process, the application of silica gel products in life is more and more widely, but some businesses in the purchase of silica gel products found that some silica gel products will send a very pungent smell, then will produce the smell why there? Poisonous? And so on?
These problems are mainly some liquid silicone manufacturers in order to save costs, use is not environmental protection, low prices of ordinary vulcanizing agent, rather than completely can pass ROHS testing environmental tasteless vulcanizing agent, vulcanizing agent is a kind of promote a catalyst, silicone raw materials vulcanization molding will evaporate after molding silicone products, only a few remaining, after 48 hours will evaporate.
Vulcanizing machine will not harm human products, but the cheap vulcanizing opportunity to produce a burnt pungent taste, volatile time in a month or so, so in the choice of silica gel gift, products as far as possible to choose better performance of tasteless silica gel products. Silicone kitchenware, in particular, has more stringent requirements.
There is basically no great taste in the rubber material. The taste problem is mainly in the curing agent and curing machine mentioned above.
Ps: the selection of curing agent should choose tasteless curing agent, after the second section basically no smell, pay attention to the second curing time do not choose 200 degrees, 155 degrees or 150 degrees, bake for 12 hours. If the temperature is high. The product is easy to aging, quality can not be guaranteed.
So when purchasing silica gel products, we should first look at the abrasion resistance, elasticity, tearing strength, and smell problems of silica gel products. If these conditions are met, it shows that the silica gel products are of good quality. If not, give up, so as not to cause financial loss.
