[0002] Zeolite molecular sieve is a hydrate of crystalline aluminum silicate metal salt. It has the structure and characteristics of crystals, with a solid skeleton on the surface. The internal holes can play the role of adsorbing molecules. The holes are connected by channels, and the molecules pass through the channels. Due to the clean nature of the holes, the pore size distribution of the molecular sieve is very uniform. The molecular sieve selectively adsorbs molecules according to the size of the holes inside its crystal, that is, it adsorbs molecules of a certain size and excludes molecules of larger substances. Zeolite molecular sieve is a selective adsorption material, and its adsorption performance for different exhaust gases is different. When zeolite molecular sieve is mainly used in the tire rubber industry, due to the complex composition of the exhaust gas in the tire rubber industry and the different exhaust gas components produced by different ingredients, and there is no relative zeolite molecular sieve produced for the tire rubber industry on the market, it is necessary to optimize the ratio of the raw materials of the zeolite molecular sieve to solve the adsorption performance of the zeolite molecular sieve in the adsorption of different VOCS gases.
