In this embodiment, the liquid silica gel is cured at room temperature or by heating to produce different molds or finished products. The silica gel can be divided into single-component silicone rubber and double-component silicone rubber, and the curing principle of the two silicone rubbers is different to a certain extent. The curing principle of the single-component liquid silica gel is room temperature curing, and the single-component liquid silica gel is cured into a certain elastomer by the action of controlled moisture. The curing time of the one-component room temperature curing silica gel depends on the curing system, ambient temperature, humidity and silica gel thickness. Generally, increasing the temperature and humidity of the environment can accelerate the curing of the one-component silica gel.
