1. Silicone rubber mold burning phenomenon and solution: Sometimes we will occasionally see a slight burning of silicon rubber products flash edge trimming silicone rubber products, silicone products, this is because unsaturated resin and After the resin product has added the peroxide curing agent, it will generate a large amount of heat in response to the resin reaction. Generally, the curing time of the resin is 3 minutes, so the mold must be released as soon as possible after 3 minutes to prevent the silicone mold from burning. phenomenon.
2. Silica gel products appear dry in the dry phenomenon and solutions: silica gel in the production process, the water evaporated, and did not transfer the right amount of water, there will be no dry phenomenon. This is not really a serious product quality problem, but there is no control of water, the shelf life of silica gel will only appear for a long time, we use silicone, when the appropriate amount of a little add a little water, stir evenly to solve these small Problem.
3. Silicon rubber products have poor pull, oil, not acid and alkali, resistance to aging and other reasons: In the process of making silicone rubber products, in order to reduce the viscosity of silicone, some manufacturers have added a lot of silicone Silicone oil, so that the silicone becomes very soft, tearing strength is reduced, tension is poor, and acid and alkali is not, so try not to recommend or add less silicone oil, you must control the amount.
