Is the desiccant poisonous? Put it in your clothes, will you? Can it be mildewproof?
The main component is calcium oxide, and its water absorption ability is realized through chemical reaction, so water absorption is irreversible. No matter the humidity of the external environment is high or low, it can keep the moisture absorption capacity greater than 35% of its own weight, which is more suitable for low-temperature storage, with excellent drying and moisture absorption effect and lower price. Can be widely used in food, clothing, tea, leather, shoes, electrical appliances and other industries. This type of desiccant is used in the most common "snow cake" at present. However, quicklime desiccant is used less now because of its strong alkaline corrosiveness. 2, silica gel desiccant
This desiccant is a different kind of silica gel, which is packed in a moisture permeable pouch. The main raw material, silica gel, is a kind of water-containing silica with high micropore structure, which is non-toxic, tasteless and odorless, with stable chemical properties and strong moisture absorption. Therefore, it is widely used to control the relative humidity of the environment in the storage and transportation of instruments, meters, equipment, leather, bags, shoes, textiles, food and medicines. , and prevent items from being affected with damp, mildew and rust. 3, montmorillonite desiccant
This desiccant is made of pure natural raw material bentonite, which is environmentally friendly, non-toxic and tasteless, and has no harm to human body. It has good adsorption performance at room temperature and general humidity, and has the effects of adsorption activity, static dehumidification and odor removal. It not only has the advantages of fast adsorption speed and high adsorption capacity, but also is non-toxic, tasteless, non-contact corrosion and non-environmental pollution. It is especially suitable for food packaging and harmless to human body. Scope of application: widely used in products that cannot be sealed by oil seal or gas phase, such as optical instruments, electronic products, medical care, food packaging and dry air sealing of military and civilian products. Properties and uses: It can be widely used for packaging and sealing containers, computers, electrical appliances, clothing, bags, handbags, shoes, medicines, food, optical equipment and so on. And electrostatic adsorption is carried out in a closed space to remove moisture and harmful elements, control relative humidity, and play a role in preventing moisture and mildew.
