| Abstract: | The synthesis of submicron 4A-zeolite as detergent assistant from water glass and bauxite in hydrothermal system with crystallization director were introduced, and the effects of various factors were investigated. The structure and performance of the product were studied also. The results showed that the optimal synthetic conditions were as follows: n(SiO2):n(Al2O3) = 1. 9 : 1, crystallization temperature 85℃, gelation time 20 min, crystallization time 30 min, granularity is 70% <1 μm and calcium exchange capacity =330 mg(CaCO3)/g(4A-zeolite). |
