When the mobile phone slightly water, but still can work, should be turned off immediately, and then put the mobile phone in the glass jar, some desiccant in the jar, cover the lid tightly, placed for a period of time will be able to suck out the moisture in the mobile phone.
Desiccant refers to the material that can remove water from the wet material, which is usually divided into two types: chemical desiccant, such as calcium sulfate and calcium chloride, which is dried by combining with water to form hydrate; Physical desiccant, such as silica gel and activated alumina, is dried by physical adsorption of water.
Moisture control is closely related to product yield. In the case of food, under the right temperature and humidity, bacteria and molds in food can multiply at an alarming rate, causing spoilage, dampness and discoloration. Electronic products will also cause metal oxidation due to high humidity, defective products. The use of desiccant is to avoid the occurrence of defective products caused by excess water.
