Chemical Name: Calcium Chloride Desiccant
Appearance: colorless cubic crystal. Typical products are white flakes, powders, granules, spheres or honeycombs.
Nature: odorless, slightly bitter taste. The relative density is 2.15 (25 ° C). It is extremely hygroscopic and is easily deliquescent when exposed to air. soluble in water. When heated to 30 degrees, it can be dissolved in water of crystallization. If it is heated continuously, it will lose moisture. When heated to 200 degrees, it will be converted into dihydrate. When heated to 260 degrees, anhydrous calcium chloride will be formed.
According to the national standard GJB2714-96 and the US MIL3464E standard, the moisture absorption of calcium oxide desiccant can be kept stable at various temperatures, high moisture resistance, good moisture absorption performance, and a saturated moisture absorption rate of more than 50%. 1.5 times the desiccant.
Calcium chloride desiccant is a desiccant with the strongest moisture absorption and moisture absorption in all desiccants. Its moisture absorption rate is usually six or seven times that of silica gel, and the moisture absorption capacity in shipping containers is more achievable. More than 300%. Therefore, it is often used for maritime container containers to prevent moisture. After all, due to the large temperature difference between day and night, the environment is seriously wet!
