Inorganic Chemicals

Cobalt is a silver gray brittle and hard metal. It has no smell at room temperature, no steam pressure and is insoluble in water, except for ultra-fine water-soluble cobalt powder. It is stable in the air, but chemically reacts with dilute acids. It is a non-volatile metal. The demand for cobalt is small and important to maintain life.

Used for powder metallurgy parts, diamond saw blades, friction materials, electric carbon products and chemical catalysts

material of tinning and surface treatment of aluminium alloy in electroplating industry

Palladium chloride, also known as palladium dichloride, palladium chloride and anhydrous chloride, is a reddish brown crystalline powder, which is easily soluble in dilute hydrochloric acid, water, ethanol, acetone and hydrobromic acid, and is easy to deliquesce in the air. Its purpose is to prepare special catalysts and molecular sieves; Preparation of non-conductive material coating; Make gas sensors, analytical reagents, etc.

Ammonia is a colorless gas with strong pungent odor. The sources of ammonia in livestock and poultry houses mainly include two aspects: first, ammonia in gastrointestinal tract comes from feces, urine and gastrointestinal digests. Urinary nitrogen mainly exists in the form of urea, which is easy to be hydrolyzed by urease to produce ammonia. On the other hand, it is produced by decomposing the through the corruption of organic substances such as accumulated feces and urine, feed residues and bedding grass. When the padding is wet, the pH is appropriate, the temperature is high, there are many faeces and the air circulation is not smooth, the production of ammonia is faster. The concentration of ammonia in livestock and poultry houses depends on the temperature, feeding density, ventilation, ground structure, feeding management level, fecal pollution removal, etc. Because ammonia is easily soluble in water, the concentration of ammonia is relatively high when the humidity of the enclosure is high.
