Product Advantages

Flaky shape with good fluidity, smooth feeding, low dust generation, less loss during transportation and loading

Standard 74% content with crystal water, mild heat release during dissolution without high-temperature splashing

High cost performance, lower raw material cost than 94% anhydrous calcium chloride, suitable for mass conventional industrial scenarios

Strong stability of prepared solution, hard to precipitate crystals, fit for long-term circulating systems

Not easy to absorb excessive moisture and melt into lumps, lower sealing requirements for storage compared with anhydrous calcium chloride

Main Industrial Applications

Road & Parking Lot Snow and Ice Melting

Melt snow and ice on urban roads, community roads and factory areas in winter; great freezing point suppression effect, evenly spread, hard to refreeze under low temperature.

Circulating & Waste Water Treatment

Chemical agent for industrial circulating water and sewage plant treatment, adjust calcium ion content, remove fluoride ions and heavy metals, assist flocculation and impurity precipitation.

Concrete Antifreeze for Construction

Additive for winter construction concrete, lower concrete freezing point to prevent frost cracking; flakes disperse easily when mixing.

Mine & Road Dust Suppressant

Dilute with water and spray on roads and mine yards to lock dust, long moisturizing time to control dust pollution.

Oil Drilling Auxiliary

Prepare low-concentration drilling fluid and fracturing fluid, stabilize well walls and reduce formation water seepage, suitable for normal and medium-low temperature drilling conditions.

Raw Material for Refrigerant & Cooling System

Produce brine refrigerant and circulating coolant for refrigeration units, hard to solidify at low temperature with lower circulation cost.

Dehumidification Auxiliary for Textile & Leather

Simple workshop dehumidification and raw material moisture proofing, absorb excess water vapor to prevent fabric and leather mildew and hardening.

Comparison

74% dihydrate flake calcium chloride

Containing crystal water, weak hygroscopicity, mild heat release, lower unit price, widely used in regular snow melting, water treatment and common refrigeration.

94% anhydrous prilled/powder calcium chloride

Zero crystal water, ultra-strong hygroscopicity, fierce heat release, higher unit price, applied in deep drying, high-concentration solution and high-efficiency desiccant scenarios.

Storage & Transportation Notes

Hygroscopic, packed with woven bags lined with inner film, store in dry and ventilated warehouse;
Avoid rain soaking and keep away from water sources during stacking;
Less deliquescent and caking than anhydrous products, but will absorb moisture and soften if exposed to air for long time, seal package immediately after use.
