Water Treatment Chemicals

Copper sulfate, also known as blue alum, with chemical formula CuSO4, is white powder without water, blue powder with water, or light grayish green due to impure. It is a soluble copper salt. The common form of copper sulfate is its crystal. Copper sulfate tetrahydrate ([Cu (H2O) 4] SO4 · H2O, copper sulfate pentahydrate) is a blue solid. Its aqueous solution is blue due to hydrated copper ions, so anhydrous copper sulfate is often used to test the existence of water in the laboratory. In real production and life, copper sulfate is often used to refine refined copper, which can be mixed with hydrated lime to produce pesticide Bordeaux liquid. Copper sulfate is a heavy metal salt, toxic, and the lethal dose for adults is 0.9g/kg. If you eat by mistake, you should immediately eat or drink protein rich foods such as milk and egg white, or use EDTA calcium sodium salt to detoxify. White anhydrous copper sulfate powder is blue after dropping into water

Acrylamide is the most important product of acrylamide and methacrylamide. Since it was used in industry in 1954, it needs to increase gradually. The polyacrylamide can be used as an additive to improve the recovery rate of petroleum; It is used as flocculant, thickener and papermaking auxiliary. A small amount of acrylamide is used to introduce hydrophilic center into oleophilic polymer to improve viscosity, softening point and solvent resistance of resin, and to introduce a center for the color receptivity of dye. Acrylamide is also often used as a component of photosensitive polymers.

Glutaraldehyde is an important saturated straight chain aliphatic cluster binary aldehyde. Although there are many reports about the toxicity of glutaraldehyde, the crosslinking of glutaraldehyde has many advantages in clinical application, and has been accepted by chemical book. Although glutaraldehyde is widely used in pharmaceutical industry and biomedical field, its toxicity, irritation and environmental pollution can not be ignored.

Acetone oxime is white flake crystal at room temperature. It is easily soluble in water, alcohol, ether and other solvents. The saturated solubility of water solution is 25% (mass percent). Its water solubility is neutral. It is easy to hydrolyze in dilute acid. It can make potassium permanganate fade at room temperature. Acetone oxime is mainly used in industrial boiler feed water chemical deoxidizer. Compared with traditional boiler chemical deoxidizer, acetone oxime has the characteristics of less consumption, high efficiency, non toxicity and no environmental pollution. It is the best drug for shutdown protection and passivation treatment of subcritical boiler. It is also an ideal product to replace hydrazine and other traditional chemical deoxidizer in medium and high pressure boiler feed water.

It is used as building materials and metallurgical flux. It is the main raw material for the preparation of calcium hydroxide and various calcium compounds. It is also a cheap alkali in the chemical industry. It is widely used in pesticide, papermaking, food, petrochemical industry, tanning, wastewater purification and so on. It can also be used for drying ammonia in laboratory and alcohol dehydration.
