Silica gel has good chemical stability and mechanical properties. Silicone products are widely used in all aspects of production and life. However, some unscrupulous merchants have used this ordinary rubber products to pretend to be a silicone product, which has caused huge losses to consumers. As a professional responsible silicone product manufacturer, we will introduce the method of quickly identifying the quality of silicone products.
What is the production process of silica gel?
First, let’s take a brief look at the production process of silica gel . Silica gel has a porous open structure, can adsorb a variety of substances, and has strong adsorption. It is slowly placed in an aqueous solution by adding dilute sulfuric acid or hydrochloric acid, and is solidified by a hydrous silicic acid gel, and dissolved in an electrolyte (Na+ and SO4). 2-Cl-) ions, after drying, can be made into silica gel.
Quickly identify the quality of silicone products
Next, I will explain to you a simple identification method: combustion method. Silicone is a very special kind of rubber. Both silicone products and ordinary rubber can be burned, while silica gel does not burn when it burns. When it burns, the ash is white. When ordinary rubber burns, it emits black smoke, while gray is black and has a strong taste. Through this, the quality of the silicone product can be identified quickly and easily.
