Product introduction
[Product Name]: Calcium chloride
[Product Category]: Aquatic calcium chloride, calcium chloride chloride
[Product introduction]: a salt composed of chlorine and calcium, chemical formula is CACL2. Slightly bitter and tasteless.
[Physical properties]: Calcium chloride is easily dissolved in water, and it will emit heat when it is soluble in water. Calcium chloride is easy to solve, so calcium chloride must be sealed and stored

1. Calcium chloride can be used as a desiccant to dry certain gas;
2. Calcium chloride is the main raw material for the production of calcium salts;
3. Calcium chloride is the precipitant of the production of colors;
4. Calcium chloride dissolved in the characteristics of water and heat placing and low freezing point, so it is used as a snow -melting agent to use it. The snow melting agent is good;
5. Calcium chloride water solution is a good freezer for ice -making and frozen machines.
Production process
There are two types of calcium chloride production processes, one is acid method and the other is alkaline method.
Acid method:
It is mainly made of lime and hydrochloric acid through chemical reactions. The reaction is first obtained by 27 liquid calcium, and then the lime milk is adjusted. After, filtering, evaporating, crystallization, heating, concentrated, etc. Calcium chloride.
Alkaline method:
1. Calcium chloride direct evaporation process. Generally, the content of calcium chloride in pure alkali waste liquid is 76.8g/L. After purification treatment, first concentrated, separated and precipitated without crystallization. Calcium.
2. Calcium chloride salt field pre -evaporating process, usually the salt field stalls are used to naturally evaporate the pure alkali waste liquid. The salt in the waste solution will be descended. The salt in the waste liquid will first be referred to. More remaining calcium chloride will be evaporated by more remaining calcium chloride, and calcium chloride will be obtained.
The differences between these two production processes: calcium chloride produced by acid method is larger than that of alkali, but there are more impurities, unstable color, taste, and acidic is cheaper than alkali method. The alkali method obtained through the subtraction process is thin and fragile, high purity, small impurities, white color, tasteless.
