Product Introduction
Drying agent refers to a substance that can remove some of the moisture from humid materials. For example, substances such as calcium sulfate and calcium chlor dry by combining with water to form hydrates; physical drying agents, such as silica gel and activated alumina, dry by physically adsorbing water. The control of is closely related to the yield of products. For food, bacteria and mold in food will reproduce at an astonishing rate under appropriate temperature and humidity, causing food spoilage, dampness discoloration. Electronic products can also be oxidized by excessive humidity, resulting in defects. The use of desiccants is to avoid the occurrence of excess moisture causing defects
Calcium chloride desiccant is an efficient adsorption material, mainly composed of calcium chloride andatinized starch. Through a chemical method, water molecules react chemically with calcium chloride, absorbing moisture from the surrounding environment and turning it into a gel, achieving the effect adsorption, thus completely eliminating any possibility of leakage. Common silica gel desiccants can only absorb 10%-27% of their own weight, while calciumide desiccants can reach 300%. The moisture absorption rate is 8-15 times that of ordinary desiccants.
After complete absorption, it does not evaporate. After moisture absorption, ordinary desiccants will release water vapor back into the air when exposed to high temperatures, as calcium chloride descants can fuse water vapor with calcium chloride into a gel state, it is not easy to evaporate.
It can be used in an environment with a temperature of5℃~90℃. Calcium chloride desiccant has good stability of active ingredients and is difficult to react with other substances except for water, so it can used in almost all marine environments.
Silica gel
is a highly active adsorption material, the main component is silicon dioxide, which is a highly active adsorption. It is usually produced by reacting sodium silicate with sulfuric acid and then undergoing a series of post-treatment processes such as aging and acid pickling. Silica gel an amorphous substance with a transparent irregular spherical shape, and its chemical molecular formula is mSiO2.nH2O.
The chemical composition and physical structure ofica gel determine that it has many characteristics that are difficult to replace with other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. internal structure of silica gel desiccant is a very fine pore network. These capillaries can absorb moisture and retain it through their physical attraction, and it is widely used as a desiccant in aviation components, computer components, electronic products, leather products, medicine, food and other industries for drying and moisture-proof. Even if silica gel desiccant is completely immersed in water, it will not soften or liquefy. It has the characteristics of non-toxic, tasteless, noncorrosive, and non-polluting, so it can be directly in contact with any item.
Silica gel desiccant is most suitable for moisture absorption in room temperature (20~32℃), high temperature (60~90℃) environment. It can reduce the relative humidity of the environment to about 4%, so the application range of desiccants is very wide.
The safety performance of silica gel: Silica gel can have a drying effect on human skin so it is necessary to wear work clothes during operation. If silica gel enters the eyes, it needs to be washed with a large amount of water and treated by a doctor as as possible. Silica gel desiccant is the only desiccant that has been certified by the American FDA and can be directly used with food and medicine. If by mistake, it will not cause harm to the human body and will not be absorbed by the human body, and can naturally be excreted from the body with feces
