Commodity: Calcium chloride Molecular formula CaCl2 H.S code 28272000 Product feature Calcium chloride is an inorganic salt, which exists as solid or liquid. Solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous. Liquid calcium chloride is a colorless, clear solution. As calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature, Specifications: Analysis Item Standard Calcium chloride (CaCl2) 74%min,77% min,94%min Total Chlorinated Alkali: (NaCl) 5.0%max Magnesium Chloride(MgCl2) 0.5%max Insoluble matter in water 0.25%max Calcium Sulfate (CaSO4): 0.2%max Ferric Oxide (Fe2O3) 0.025%max Heavy Metal as Cu., Pb., Cd., Cr., Hg., As 0.005%max Application Mainly used in drying, melting snow for airport express and street, concrete desiccant and concreting fast, removing dust and oil industry.

Calcium hypochlorite is a chemical compound with the formula Ca(ClO)2, commonly used as a powerful disinfectant and sanitizer. It is often found in the form of white granules or tablets and is a key ingredient in various water treatment processes, including the purification of swimming pool water, drinking water, and wastewater. Calcium hypochlorite releases chlorine when dissolved in water, which effectively kills bacteria, viruses, and algae, making it an essential tool for maintaining water quality and safety. Additionally, it is employed in sanitation and cleaning applications, particularly in industries like healthcare, agriculture, and food processing, where its strong oxidizing properties help control and prevent the spread of infections and contaminants. Its role in ensuring clean and safe water supplies and hygienic environments makes calcium hypochlorite a critical chemical compound for public health and sanitation.

Calcium carbide (CaC2) is a pivotal inorganic compound known for its industrial form as gray-black block-like material, often displaying purple or gray cross-sections. When exposed to water, it undergoes an energetic reaction, producing acetylene gas and releasing heat. Primarily, it's employed for two key purposes: as a source of acetylene gas with applications in welding, cutting, and fuel, and as a raw material in organic synthesis for chemicals like vinyl chloride and synthetic resins.

Product introduction: Calcium is a silvery white metal that is harder and heavier than lithium, sodium, and potassium; It melts at 815 C. The chemical nature of metallic calcium is very active. In the air, calcium is quickly oxidized and masked with an oxide film. When heated, calcium will burn and emit a beautiful glow of brick red. Calcium and cold water have a slower effect, and intense chemical reactions occur in hot water to release hydrogen (lithium, sodium, and potassium can cause intense chemical reactions even in cold water). Calcium is also easily combined with halogens, sulfur, nitrogen, and the like. 1,product name:calcium metal 2,Shape :powder, lump and granulates 3,CAS:7440-70-2 4,Density:1.54g/cm 5,Melting point:850C 6,Boiling point:1440 C(lit.) 7,Application:Wheel keel Product use: At present, in the steel industry, the main use of metal calcium is to process into metal calcium particles, and then to make calcium iron wire or pure calcium wire, and finally used for steel refining outside the furnace, its role is to desulfurization, deoxidation, increase the fluidity of molten steel. Promote the rapid rise of inclusions in molten steel, generally used in the production of high-quality steel; as a dehydrating agent to produce anhydrous alcohol; in the petroleum industry, as a desulfurizing agent, in the metallurgical industry, it is used to deoxidize or desulfurize . However, calcium compounds have a very wide range of uses, especially in the construction industry.

Calcium carbide is an inorganic compound, white crystal, industrial products are gray black blocks, cross-section purple or gray. It reacts violently with water, forming acetylene and releasing heat. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. Also used in organic synthesis, oxyacetylene welding and so on. It is called calcium carbide( CaC2). It is a hard lump and the cross section is dark grey or brown. 2. It is lumpy substance, its surface is a little deep gray, has slight nasty smell. 3. It can produce acetylene gas when met water, it can burn when meets fire. 4.The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%). 1.The main raw material for producing acetylene gas. 2.Cutting and welding for metal material. synthesize polyvinyl chloride(PVC). 4.Fruit catalyst. 5.The basic material for organic synthesis and calcium cyanamide 6.Reacting with water to bring about ethine. 7. Reacting with nitrogen to product lime nitrogen. 8.The desulfurizer in steel industry.
