Calcium chloride 10043-52-4, industrial calcium chloride, desiccant calcium chloride

Calcium Chloride Product Details Manual

• 
• 
  
• I. Product Overview and Classification
  
  
  Calcium chloride is a typical ionic halide. It is a white solid at room temperature, odorless with a slightly bitter taste, and has extremely strong hygroscopicity. It is highly deliquescent when exposed to air, easily soluble in water and releases a large amount of heat (dissolution heat is approximately 83.7 kJ/mol), and its aqueous solution is slightly alkaline (pH 4.5-9.5). It can be divided into various types according to the content of crystal water and morphology, which are suitable for different application scenarios:
  
  
  Table

• Dust prevention and sand fixation: Absorb moisture in the air to form a moist layer, effectively suppress dust, and be used in mining area roads, construction sites, and mine stockyards.
• 

Concrete admixtures: Accelerate concrete hardening, improve early strength, enhance frost resistance, lower the freezing point of concrete, and are used in winter construction and emergency repair projects.

2.2 Industrial and Chemical Fields

• 
  

  Desiccants: Drying industrial gases such as nitrogen, oxygen, and hydrogen, as well as organic solvents such as alcohols and ethers, used in drying tubes, drying towers, and molecular sieve regeneration

  
  

  Refrigerants / Coolant carriers: Mixed with water to prepare low-temperature cooling fluids (with a freezing point as low as -55℃), used in cold storage, ice factories, and industrial refrigeration systems

  
  

  Oil drilling: Used as a drilling fluid additive to inhibit clay swelling, stabilize well walls, control mud viscosity and water loss, and improve drilling efficiency
  
  
• 
• Metal processing: Aluminum-magnesium metallurgical protective agents and refining agents prevent metal oxidation and improve product purity.

  
  

  Wastewater treatment: As flocculants, they remove phosphate and heavy metal ions, adjust pH value, and improve sludge dewatering performance.
• 
• 2.3 Food Processing Field (Food-grade Special Use)

  

  Bean product coagulants: cause the protein in soymilk to coagulate to form products such as tofu and dried tofu, in line with the GB2760 standard

  
  

  Food preservatives: inhibit the growth of microorganisms, extend the shelf life of fruits, vegetables and seafood, and maintain the taste and texture of food

  
  

  Beverage additives: adjust mineral content, improve taste, used in sports drinks and tea drinks (maximum addition amount 3.7g/kg)

  
  

  Canned food processing: maintain the shape of food, prevent the softening of contents, and improve product stability

  
  
• 2.4 Agriculture and Aquaculture Fields

  

  Fruit tree calcium supplementation: Prevents and controls bitter pit and pitting disease in fruits such as apples and pears, improves fruit firmness and storage and transportation resistance.

  
  

  Aquaculture: Regulates the calcium ion concentration in water, promotes the molting and growth of shrimp and crabs, increases survival rate, and improves water quality.

  
  

  Feed additives: Supplement calcium for animals, enhance bone development, improve eggshell quality, applicable to poultry, livestock, and aquaculture.

  
  

• 2.5 Other Innovative Applications

  
  

  Desiccant packs: Used for moisture prevention in electronic products, leather products, clothing, shoes and hats, and precision instruments.

  
  

  Fire-extinguishing materials: Used to make flame retardants to improve the fire resistance of materials, and applied in the treatment of textiles, wood, and paper.

  
  

  Oilfield exploitation: Used as a component of completion fluids and workover fluids to stabilize formations and prevent clay swelling.

  
  

  Rubber industry: Used as a coagulant to promote the coagulation of rubber latex and improve rubber quality.

  
  

• III. Technical Parameters and Specifications

  
  

  3.1 Physical Property Parameters

  
  

  Table

1. Operating Specifications:

   
   

   When dissolving, calcium chloride should be slowly added to water, and stirred to dissipate heat. It is strictly forbidden to pour water into calcium chloride (to prevent boiling and splashing).

   
   

   Emergency water sources and eye washers should be equipped in storage and use areas.

   
   

   After using food-grade products, containers should be thoroughly cleaned to avoid cross-contamination.

   
   

   Emergency Treatment:

   
   

   Leakage handling: Cover and collect solid leaks with dry sand; absorb liquid leaks with sand or adsorbent materials, and dispose of them properly to prevent them from flowing into sewers.

   
   

   Fire handling: It is a non-flammable substance, and water, dry powder, or carbon dioxide can be used for fire extinguishing.

   
   

   First aid measures:

   
   

   Eye contact: Immediately lift the eyelids and rinse with plenty of flowing water or physiological saline.

   
   

   Skin contact: Remove contaminated clothing and rinse thoroughly with soapy water and water.

   
   

   Inhalation: Quickly move away from the scene to a place with fresh air and keep the respiratory tract unobstructed.

   
   

   Ingestion: Drink a sufficient amount of warm water, induce vomiting, and seek medical attention.
