What is the dehumidification principle of calcium chloride?
06 Mar,2023
Principle of calcium chloride desiccant bag 1. At present, the chemical composition of the commonly used moisture-proof and dehumidifier materials is mainly calcium chloride and silica gel. Calcium chloride is a deliquescent white crystal with granular, massive or lamellar structure; It has strong hygroscopicity and is liquid after absorbing moisture. The upper layer of this type of hygroscopic box is covered with a film, the middle layer is hygroscopic agent, and the bottom layer is water storage layer. 2. When the hygroscopic agent absorbs the moisture in the air of the cabinet, it will turn into liquid flowing to the bottom. At first, when the hygroscopic agent is still at a high concentration, the hygroscopic rate is fast. Once the humidity of the space drops to a certain degree, the hygroscopic rate will slow down. If the humidity of the environment has not increased, the life of the hygroscopic agent will be extended. The amount of water molecular weight per unit volume and the probability of movement collision. For example, if the moisture in the cabinet is reduced from 90% to 60%, the hygroscopic agent may have consumed about half, but at this time, the water molecules in the air in the cabinet are also reduced by 30%, and the probability of water molecules flowing collision and reacting with the hygroscopic agent through the film is reduced. The principle of using calcium chloride as dehumidifier: it can absorb water molecules in the air and reduce the humidity in the air depending on the strong hygroscopicity of calcium chloride. Use: Calcium chloride has a wide range of uses. Industrial grade calcium chloride can be used as oil drilling, desiccant, snow melting agent, refrigerant, coagulant, etc. Food grade calcium chloride is mostly used as food additives, which can play a role in coagulation, preservation, thickening, nutrition and other effects. Calcium chloride aqueous solution is an important refrigerant for refrigerators and ice making. It can accelerate the hardening of concrete and increase the cold resistance of building mortar. It is an excellent building antifreeze. It is used as a port defogger, road dust collector and fabric fire retardant. Calcium chloride is a solid particle of porous block. It can remove moisture and odor by adsorbing active static dehumidification and odor. The adsorption process is a physical reaction. Use the physical properties of calcium chloride. Calcium chloride, the main raw material of calcium chloride desiccant, is refined from calcium carbonate and hydrochloric acid through reaction synthesis, filtration, evaporation concentration, drying and other processes. White porous block, granular or honeycomb solid. The taste is slightly bitter and odorless. The aqueous solution is colorless. It is mainly used as raw material for inorganic chemical production of other calcium salts; It is also used as a desiccant for gases, and as a calcium fortifier, curing agent, chelating agent, desiccant, etc. in the food industry. Calcium chloride desiccant has the functions of adsorption, static dehumidification and odor removal. It not only has fast adsorption speed, high adsorption capacity, tasteless, non-contact corrosivity, and no environmental pollution, but is widely used in oil seals, optical medicine, and health food.
