We know that calcium chloride is a common desiccant. The adsorption speed is fast, the adsorption rate is over 90%, non-corrosive, and its price is cheaper than other desiccants, so calcium oxide desiccants are widely used in daily life.
Calcium chloride desiccant is different from other common desiccants. Other desiccants will become lumps after absorbing moisture, while calcium chloride desiccant has gelling agent added to it, so that calcium chloride desiccant will become gel . If it turns into a gel, it can prevent the water absorbed by the desiccant from flowing out, and prevent the desiccant from damaging the article.
The biggest difference between calcium chloride desiccant and desiccants produced by other manufacturers is that the moisture absorption rate is higher. Traditional silica gel desiccants can only achieve a moisture absorption rate of 27%, and montmorillonite desiccants can only achieve a moisture absorption rate of 30%. Calcium chloride desiccant can absorb more than 300% of its own water vapor because of the addition of high-purity calcium chloride, which enhances its moisture absorption capacity.
Ordinary desiccants generally have their own applicable temperature, and the temperature is generally below 50 degrees. Calcium chloride desiccant is different from traditional desiccants. The temperature range that can be used is minus 5 degrees to 90 degrees. In addition to the wider range of temperature, the usable time is also longer, which can reach three months.
Used in metal, food, communication, electronics, military building materials, light industrial products, containers and other fields that require moisture protection. Widely used in oil and gas products that cannot be sealed, such as optical instruments, electronic products, YL health care, food packaging and product dry air storage, product hygroscopic activities, static dehumidification and odor removal effects, etc.
The reason why the calcium chloride desiccant will generate heat during the moisture absorption process is that it has a chemical reaction with the humidity of the air. As long as the desiccant undergoes a chemical reaction during the process of absorbing water, it will release a certain heat source, so in this process calcium chloride desiccant will be somewhat hot on contact. There are two kinds of chemical reactions, one is endothermic (it cannot proceed spontaneously, and heating equipment is required for the reaction), and the other is exothermic when the desiccant absorbs water. Release of heat is a slow reaction process, such heat will be released gradually, so when the calcium chloride desiccant is working to absorb moisture, it is always hot. As long as the desiccant is still valid, the calcium chloride desiccant is long-term moisture-absorbing, so the heat will gradually be carried out when the desiccant is working.
