Product Application
1. Roads and Environment: As a snow-melting agent and dust suppressant, it quickly melts snow and ice and suppresses road dust.
2. Drying and Moisture Absorption: As a highly efficient desiccant, it is used to dry various gases such as air, nitrogen, and oxygen, as well as organic liquids.
3. Construction Industry: As a setting accelerator and antifreeze component added to concrete, it accelerates setting and improves early strength.
4. Food Industry: As a coagulant (used in tofu and dried bean curd), thickener, and preservative.
Key Features: Extremely strong hygroscopicity, exothermic dissolution in water, and extremely low freezing point.
