Embodiment 1
[0015] 213.7 g silica sol [40, SiO 2 % (weight), all the other are water, the same below] is A solution, 81.0 grams of solid aluminum sulfate [chemically pure, Al 2 (SO 4 ) 3 18H 2 O, the same below] was dissolved in 140 milliliters of water to obtain solution B, and 54.5 grams of solid sodium hydroxide (chemically pure) was dissolved in 113 milliliters of water to obtain solution C. Add 200 ml of water into a container with a stirring device, turn on the stirring device, and add the three solutions of A, B, and C into the container at the same time in proportion to the flow, within 45 to 90 minutes, the three solutions are added at the same time, and continue to stir for 15 minutes Above, add 8.3 grams of ammonia water [chemically pure, NH 3 25.5% (weight)], and then stirred for 1 to 3 minutes. Then transfer the slurry into a 2-liter crystallization tank with a stirring device, seal the crystallization tank, turn on the stirring device, start heating, raise the temperatu...
Embodiment 2
[0020] 230.4 grams of silica sol was solution A, 51.1 grams of solid aluminum sulfate was dissolved in 191 milliliters of water to obtain solution B, and 33.2 grams of solid sodium hydroxide was dissolved in 120 milliliters of water to obtain solution C. Add 380 ml of water into a container with a stirring device, turn on the stirring device, and add the three solutions of A, B, and C into the container at the same time in proportion, and continue stirring for more than 15 minutes after adding the three solutions at the same time, then add 5.1 grams Ammonia [chemically pure, NH 3 25.5% (weight)], and then stirred for 1 to 3 minutes. Then transfer the slurry into a 2-liter crystallization tank with a stirring device, seal the crystallization tank, raise the temperature in the crystallization tank to 180° C. within 2 hours, and keep the temperature constant for 28 hours. Then cool, filter and recover the solid product, wash with water, and dry overnight at 110°C to obtain the s...
Embodiment 3
[0025] 239.4 g industrial water glass (26.02 wt% SiO 2 , 7.45 wt% Na 2 O, the rest is water) is A solution, 41.6 grams of solid aluminum sulfate and 17.8 grams of sulfuric acid (chemically pure) are dissolved in 228 milliliters of water to obtain B solution. Add 300 ml of water to a container with a stirring device, turn on the stirring device, and add the two solutions A and B into the container simultaneously in proportion to the same flow. After the two solutions are added simultaneously, continue stirring for more than 15 minutes, and then transfer the slurry into In the crystallization kettle with stirring device, the crystallization kettle was sealed, and then 3.2 grams of liquid ammonia (purity of more than 99%) was bubbled into the crystallization kettle, and the temperature in the crystallization kettle was raised to 170 ° C, and the constant temperature was 60 °C. Hour. The solid product was recovered by cooling and filtration, washed with water, and dried at 110° ...
