Research on the Application of Zeolite Molecular Sieve in the Coating End of Rail Transit
Zeolite molecular sieves is hydrate of crystalline aluminum silicate metal salt.Due to its unique structure and excellent performance,it has been widely used in adsorption separation,catalysis and other fields.In this article,the adsorption and separation performance of zeolite molecular sieves for VOCs(volatile organic compounds)molecules was emphasized.With butyl acetate and styrene as waste gas sources,the adsorption/desorption performance,hydrophobicity,and other properties of four different zeolite molecular sieves were studied through comparative experiments.The most suitable zeolite molecular sieve was selected to study its application in the treatment of waste gas at the end of rail transit product coating operations.The experimental results indicated that different brands of zeolite molecular sieves exhibit different advantages in the adsorption and desorption processes of different types of exhaust gases,as well as in the study of dynamic water adsorption capacity.Overall,Brand A zeolite molecular sieve is more suitable for the waste gas treatment requirements in this experiment.Therefore,when selecting the type of zeolite molecular sieve in the waste gas treatment device,appropriate zeolite molecular sieve should be configured according to the main components and content of the coating waste gas listed in the MSDS to ensure effective adsorption of VOCs molecules.
