Molecular sieve for micro heat absorption dryer and preparation process thereof

Abstract

The application relates to the technical field of molecular sieves, and particularly discloses a kind of molecular sieves for micro-heat suction dryer and a preparation process thereof.A kind of molecular sieves for micro-heat suction dryer, including the following weight parts of raw materials: zeolite molecular sieve raw powder 60-80 parts, nano silicon dioxide 10-15 parts, sodium carboxymethyl cellulose 5-8 parts, bentonite 10-20 parts, nitric acid 3-5 parts, sesbania powder 3-5 parts, anti-cracking agent 1-3 parts, the zeolite molecular sieve raw powder is surface modified by trimethylchlorosilane.The molecular sieves for micro-heat suction dryer prepared by the application are surface modified by trimethylchlorosilane in advance on the surface of zeolite molecular sieve raw powder, then through the mutual synergistic effect of each component of silicon dioxide, sodium carboxymethyl cellulose, sesbania powder and nitric acid, the overall strength of the molecular sieve is improved, and the breaking and cracking of the molecular sieve is reduced.
