Desc：At present, the traditional acid dyeing bath condition dyeing method is still used in the dyeing and finishing of polyester fabrics. The method has the disadvantages of poor quality, low output and high production cost in the production process, and it is more and more unsuitable for the production needs, especially for the dyeing of polyester fabrics after alkali treatment. The root of these problems lies in the lack of basic dyeing auxiliaries, while sodium hexametaphosphate/SHMP technical grade is a widely used dyeing auxiliaries in phosphate products.

Desc：Phosphate is the most widely used food quality improver in the world. In all fields of food production, phosphate plays an irreplaceable role in improving the quality of food, especially in meat processing. At present, there are many kinds of phosphates approved for use in food additives in China, including sodium tripolyphosphate/STPP, sodium hexametaphosphate/SHMP, sodium pyrophosphate, trisodium phosphate, disodium hydrogen phosphate, sodium dihydrogen phosphate, sodium acid pyrophosphate, etc.

Desc：At present, acidifier has been widely used in piglet feed, poultry feed, silage and other fields as an effective, pollution-free and residue-free feed additive. Formic acid feed grade can greatly improve the function of feed. It can not only reduce the pH value of gastrointestinal tract, but also have good bacteriostasis and bactericidal effect.

Desc：With the development of modern industry, food additives have become an indispensable part of life. Tetrasodium pyrophosphate/TSPP is also one of the food additives.

Desc：Aquatic farmers know that the hardness of the water body is very important, not only for the conversion of organic matter, but also for reducing the toxicity of toxic substances (heavy metals, hydrogen sulfide), but also for the growth and development of algae and prawns. The hardness of water refers to the content of divalent and multivalent metal ions in the water, including calcium, magnesium, iron and so on. Therefore, to maintain the hardness of the water body, it is also a good choice to use feed grade calcium formate to supplement calcium ions.

Desc：Chemical formula of sodium hexametaphosphate/SHMP: na6p6o18. It is a polar inorganic compound, soluble in water, with a relative density of 2.484 and a melting point of 616 ℃ (decomposition). The solubility in water is large, but slow.
