Desiccant For Shoes

The types of desiccant to used for shoes:

At present, the main shoe cap desiccant is silica gel desiccant, montmorillonite desiccant, calcium chloride desiccant, fiber desiccant.

1, quicklime desiccant

The main component of the quicklime desiccant is calcium oxide, and its water absorption capacity is achieved by a chemical reaction, so water absorption is irreversible. Regardless of the humidity of the external environment, it can maintain a moisture absorption capacity of more than 35% of its own weight, is more suitable for low temperature storage, has excellent dry moisture absorption, and is relatively inexpensive. Can be widely used in food, clothing, tea, leather, shoes, electrical appliances and other industries. This type of desiccant is currently used in the most common "snow cake". However, due to the corrosive nature of the lime, the quicklime desiccant often causes harm to the eyes of children or the elderly, and has been gradually eliminated.

2, silica gel desiccant

The desiccant is a different type of silica gel packaged in a moisture permeable pouch. The main raw material silica gel is a high microporous structure of hydrous silica, which is non-toxic, odorless, odorless, chemically stable, and has strong hygroscopic properties. Therefore, it is widely used in the storage and transportation of instruments, instruments, equipment, leather, bags, shoes, textiles, food, medicines, etc. to control the relative humidity of the environment to prevent moisture, mildew and rust. It is used in, for example, xylitol, and it is also the only desiccant approved by the European Union.

3, montmorillonite desiccant

The desiccant adopts pure natural raw material bentonite, which is environmentally friendly, non-toxic and tasteless, and has no damage to the human body. It has good adsorption performance at room temperature and general humidity, and has the functions of adsorption activity, static dehumidification and odor removal. It not only has fast adsorption speed, high adsorption capacity, is non-toxic, odorless, non-contact corrosive, and has no environmental pollution, especially for food packaging, and is harmless to the human body. Scope of application: Widely used in products that cannot be sealed with oil or gas, such as optical instruments, electronic products, medical care, food packaging, and dry air storage for military products and civil products.

4, calcium chloride desiccant

The main raw material of calcium chloride desiccant is calcium chloride and hydrochloric acid, which are refined by reaction, synthesis, filtration, evaporation, concentration and drying. White porous block, granular or honeycomb solid. The taste is bitter and odorless. The aqueous solution is colorless. It is mainly used as a raw material for the production of various other calcium salts in inorganic chemicals; it is also used as a desiccant for gases, and a dehydrating agent for the production of alcohols, esters, ethers and acrylic resins. Used as a calcium enhancer, curing agent, chelating agent, desiccant, etc. in the food industry.

5, fiber desiccant

Fiber desiccant is made from pure natural plant fiber through special craftsmanship. Among them, the coated fiber desiccant sheet is convenient and practical, and does not occupy space. Its moisture absorption capacity reaches 100% of its own weight, which is unmatched by ordinary desiccant. In addition, the product is safe, hygienic and affordable, making it an ideal choice for many biological, health foods and pharmaceuticals.
