| Questions And Answer | Back Directory | [Preparation]
1809 kg of fluorite powder, 335 kg of silica sand, and 1858 kg of sulfuric acid were sequentially added to a reaction converter to prepare fluorosilicic acid. The solution with a concentration of 20–22°Be′ was obtained by absorption in an absorption tower. After removing sulfates, the solution was transferred to a neutralization vessel and neutralized to a pH of 3–4 with the addition of a suspension of calcite powder. The solution was filtered, and the filtrate was fed into an evaporator, concentrated, and then transferred to a crystallizer for cooling and crystallization. After drying, magnesium fluorosilicate was obtained. | [Application]
Magnesium fluorosilicate can be used as a hardener in concrete to improve its strength and hardness, and as a waterproofing agent. It can also be used in silica surface treatment for fluorination. Due to its toxicity, magnesium fluorosilicate can be used as an insecticide and can be used as a fabric insect repellent or as an active ingredient in insecticides. It can also be used in ceramics manufacturing. Therefore, magnesium fluorosilicate has a wide range of applications, serving as a concrete strengthener, concrete retarder, rubber latex coagulant, preservative, and textile moth repellent. |
