Embodiment 1
[0029] Add 636.96g of sodium hydroxide and 420.43g of potassium hydroxide to 5L of sodium metaaluminate solution, so that OH - / SiO 2 The molar ratio is 2.34, K 2 O / Al 2 o 3 The molar ratio is 1.5, and the solution is mixed with 4.125L water glass solution in parallel, so that the SiO 2 / Al 2 o 3 The molar ratio is 2.0, where H 2 O / Na 2 The molar ratio of O is 20, and the amount of seed added is Al 2 o 3 3% by mass, the prepared gel mixture was stirred and aged at room temperature for 30 minutes, then statically aged at 70°C for 6 hours, and statically crystallized at 100°C for 3 hours. After the crystallization is completed, the generated crystals are rapidly cooled and filtered, washed with deionized water until the pH value drops to 9, and the filter cake is dried at 80°C.
