Common Types
We offer the following Product introduce:
Ammonium bicarbonate
Ammonium bicarbonate is a white compound with the chemical formula NH4HCO3. It is in the form of granular, plate-like or columnar crystals and has an ammonia odor. Ammonium bicarbonate is a carbonate, so it must not be placed together with acid, because the acid will react with the ammonium bicarbonate to produce carbon dioxide, which will cause the ammonium bicarbonate to deteriorate.
Trisodium Phosphate (TSP)
It easily deliquesces and weathers in dry air, producing sodium dihydrogen phosphate and sodium bicarbonate. It is almost completely decomposed into disodium hydrogen phosphate and sodium hydroxide in water. In the electroplating industry, it is used to prepare surface treatment degreasing liquid and alkaline detergent for unpolished parts.
Thiourea Dioxide
Thiourea dioxide is a substitute for insurance powder. It is an inorganic compound with strong reducing properties, good thermal stability, and convenient storage and transportation. This product can be used as a reducing agent, bleaching and decolorizing agent, plastic stabilizer, organic synthetic antioxidant and effector of photosensitive materials. It has been widely used in printing and dyeing, papermaking and other industries.
Sulfamic acid
Sulfamic acid is an inorganic solid acid formed by replacing the hydroxyl group of sulfuric acid with an amino group. Its chemical formula is NH2SO3H and its molecular weight is 97.09. It is generally a white, odorless rhombic flake crystal with a relative density of 2.126 and a melting point of 205°C. In water and liquid ammonia, at normal temperature, as long as it is kept dry and not in contact with water, solid sulfamic acid is not hygroscopic and is relatively stable.
Calcium hydroxide
Calcium hydroxide is an inorganic compound with a chemical formula of Ca(OH)2 and a molecular weight of 74.10. Commonly known as slaked lime or slaked lime. It is a white hexagonal powder crystal.Calcium hydroxide is a strong alkali with bactericidal and antiseptic capabilities, and is corrosive to skin and fabrics. Calcium hydroxide is used to make bleaching powder, hard water softeners, disinfectant pesticides, hair removers for tanning, sugar refining and building materials, etc.

Precautions
Keep the container sealed, store in a cool, dry place, and store in a cool, dry, ventilated warehouse. Do not put it together with NaOH or Ca(OH)2.
Pay attention to moisture, rain and sun exposure during storage and transportation. Be careful when handling to prevent damage to the packaging.
It is strictly prohibited to mix and transport with oxidants, acids, food chemicals, etc. During transportation, they should be protected from exposure to the sun, rain, and high temperatures.
In the event of a fire, you can spray water, spray, or use dry powder, carbon dioxide, or foam fire extinguishing agents to extinguish the fire.
