Our packaging can be customized to meet all your needs

At the same time, relying on our own geographical location and resource advantages, our company is committed to the optimization of a variety of chemical supply chain, including magnesium chloride, sodium metabisulfite, sodium bicarbonate, calcium chloride, magnesium sulfate, polyaluminium chloride, aluminium sulfate, industrial salt, soda ash etc.
Main application areas:
1. Dehumidification and drying: Widely used in applications such as dehumidifiers and desiccants, it can effectively absorb moisture and reduce humidity in the air. It is commonly used in refrigeration, air conditioning, gas purification, and moisture-proof packaging of electronic products.
2. De icing and anti freezing: Calcium chloride dihydrate is used for de icing and anti freezing in areas such as roads, airport runways, etc. Although it is not as strong as anhydrous calcium chloride, it still has a certain anti freezing ability.
3.Water treatment and hard water softening: As a hard water softener, it can be used to remove calcium and magnesium ions from water during the water treatment process, reducing the hardness of water.
4. Chemical industry: used as a source of calcium chloride and can also participate in certain chemical reactions, commonly used in fields such as ore processing and petroleum drilling.
5. Food industry: Sometimes used in food processing as a preservative or calcium source to help extend shelf life.
6. Construction industry: Used as antifreeze additives for building materials such as concrete and mortar to improve construction stability in low-temperature environments
