Abstract
The invention discloses a hollow glass 4A molecular sieve and a preparation method thereof. The preparation method mainly comprises the following steps: agitating and mixing formed raw materials, i.e. Ca(OH)2, 2/3K2O*1/3Na2O*Al2O3*2SiO2*9/1H2O and Al2O3*2SiO2*2H2O according to a certain weight proportion, granulating and adding tanning agent myrica for particle polishing treatment, and adding into a roasting furnace for sintering; and packaging after detection separation and screening. The invention has the beneficial effect that the preparation method is simple, is low in raw material cost, can be used for preparing various chemical gas and liquid, drugs, electronic materials, hollow glass and other industrial drying agents and has a good drying effect.
