Introduction To Desiccant

Desiccant refers to a substance that can remove part of the moisture in a moist substance. For example, calcium sulfate and calcium chloride are dried by combining with water to form hydrates; physical desiccants, such as silica gel and activated alumina, are dried by physically adsorbing water. The control of moisture is closely related to the yield of the product. In terms of food, under the appropriate temperature and humidity, the bacteria and mold in the food will multiply at an alarming rate, which will spoil the food and cause moisture and color. change. Electronic products can also cause metal oxidation due to excessive humidity, resulting in defects. The use of desiccant is to avoid the occurrence of defective products caused by excess water.
