| | | Calcium chloride is made from the effluents of soda ash production, which used to
be discharged into the Bohai Sea and caused serious pollution problem. After the
processing from soda effluents to calcium chloride, the pollution has been effectively
eliminated.
Calcium chloride is an inorganic salt, which exists as a solid or a liquid. Solid
calcium chloride is a white, crystal substance in the form of flake, granule or
powder. With different crystallized water contents, it can be dihydrate or anhydrous,
which are widely used in oil drilling, food producing, road de-icing.

To obtain homogeneous solution, efficient dispersion is necessary. The most convenient
method of dispersing these products is with a polymer eductor or a commercially
available dry powder feeder unit. Solution should be made up at 0.1 - 0.3%
solid. Make-up water temperature should be between 10 and 40°C for optimum
product performance. Following dispersion into agitated water, stirring should
continue for about an hour to ensure complete dissolution. Stirring China | |
