Silicic acid, aluminum potassium sodium salt - Production method
water glass is boiled with steam by hydrothermal synthesis method to prepare an aqueous solution with a relative density of 1.2~1.25, impurities are removed by sedimentation, and supernatant is taken for use. The solid aluminum hydroxide and sodium hydroxide are heated and dissolved according to the mass ratio 1.2:1 to make sodium metaaluminate solution for later use. In order to prevent the hydrolysis of the sodium metaaluminate solution, it is best to use the newly prepared solution.
Sodium silicate, sodium metaaluminate and sodium hydroxide are mixed according to a certain molar ratio (generally A12O3:SiO2:Na2O:H2O = 1:2:3:185). Under stirring, the gel is reacted at about 80 ℃ for 30 min. The generated gel is heated to 90 ℃ for 1h, and the gel is continuously heated to 102 ℃ 2 ℃ for crystallization for 4h to obtain crystal powder. After filtration and washing, potassium chloride is added for ion exchange (exchange degree 40%), and then filtered and washed, dried, kneaded with adhesive, molded, burned and activated to obtain 3A molecular sieve.
