The mainstream industrial calcium chloride available on the market falls into two categories: dihydrate calcium chloride CaCl2·2H_2O, 74% content) and anhydrous calcium chloride CaCl2, 94% content). Many buyers fail to understand their differences, resulting in poor application performance and unnecessary cost losses due to improper selection.
Dihydrate calcium chloride 74% is the most widelycirculated product with favorable cost performance. Common forms include flakes and spherical pellets. It contains crystal water, delivers moderate moisture absorption capacity and is less prone to rapid caking.
Application Scenarios:
Snowmelting and deicing for roads and airports
Dust suppression for mines, stockyards and highways
Preparation of brine for coldstorage refrigeration systems
Earlystrength and antifreeze agent for concrete in winter construction
Wastewater treatment and production of magnesiumoxide building materials
It is ideal for largevolume project procurement with excellent overall costeffectiveness.
Anhydrous calcium chloride 94% features higher active ingredient content and far stronger moisture absorption capacity than the dihydrate type. It readily absorbs moisture from ambient air, so higher requirements for storage and moistureproof packaging are required. It is mostly supplied as spiky pellets and powder.
Application Scenarios:
Desiccant for industrial gases, equipment and containers
Preparation of drilling and completion fluids for oilwell operations
Chemical dehydration processes with strict requirements for impurities and moisture
Deep snowmelting under lowtemperature conditions
Brief selection principles: Choose 74% dihydrate calcium chloride for costeffective purposes such as snow melting, dust control and refrigeration brine. Choose 94% anhydrous calcium chloride for working conditions requiring strong moisture absorption and high purity.
Apart from content, physical form also affects practical performance. Spiky pellets have good flowability and low dust generation, suitable for automatic mechanical feeding. Flakes dissolve fast for onsite solution mixing. Powder dissolves the fastest but is highly susceptible to caking if not properly stored.
