For example, calcium sulfate and calcium chloride are dried by combining with water to form a hydrate; a physical drying agent such as silica gel and activated alumina is dried by physically adsorbing water. The control of moisture is closely related to the yield of the product. In the case of food, under the proper temperature and humidity, the bacteria and mold in the food will multiply at an alarming rate, causing the food to spoil, causing moisture and color. change. Electronic products can also cause oxidation of metals due to excessive humidity, which can cause defects.
