Application effect of technical sodium hexametaphosphate(SHMP) in water softener

Softener is a highly effective chelating and dispersing agent. It has excellent chelating power to Ca, Mg and other metal ions. It is essential for industrial soft water such as textile printing and dyeing and washing process.

Sodium hexametaphosphate(SHMP) is a widely used water softener. Because Ca2+ or Mg2+ which causes hardness in water enter into the molecule of sodium hexametaphosphate(SHMP), it becomes a very stable soluble complex: Na2 [Ca2 (PO3) 6] and Na2 [Mg2 (PO3) 6]. The Ca2+ or Mg2+ in this complex is even as sensitive as ammonium oxalate in softened water. It is also impossible to find Ca2+ ions.

Sodium hexametaphosphate(SHMP) is soluble in water. The aqueous solution is alkaline and the PH of 1% aqueous solution is 9.7. Phosphite is gradually hydrolyzed into phosphite in water, which has good ability to complex metal ions. It can complex with Ca, Mg, Fe and other metal ions to form soluble complexes and soften hard water.

Sodium hexametaphosphate(SHMP) produced by CDchem has a strict quality control system, and the product quality is quite stable. CDchem has our own phosphorus mine. It takes the lead in realizing the concept of "integration of mineralization" and "green development", ensuring the quality and reducing the cost of raw materials.

The manufacturer tells you the dispersing effect of sodium hexametaphosphate

The dispersing effect of sodium hexametaphosphate is due to its hydrolyzed anions adsorbed on the particle surface. In order to improve the dispersing effect, the hydrolysis degree of the dispersant can be selectively increased. It is believed that we all know that the function of dispersant is to increase the distance between the large particles to be dispersed in the solution and reduce the viscosity of the whole solution. However, the amount of   sodium hexametaphosphate   used in the dispersion of different substances is also different. In the process of material dispersion, the surface of large particles adsorbs the dispersant to form a double electric layer, and anions are closely adsorbed on the surface of particles, which is called surface ions. Ions with opposite charges in the medium are called anti ions. In the process of medium movement, particles and particles, as well as the electric double layer and the electric double layer have the same charge, which will generate elec

Non-antibiotic growth promoter potassium diformate helps pig industry return to its essence

  The high profitability of the pig industry will not last, and the future development of the industry still needs to return to the essence of pig raising. The non-antibiotic growth-promoting agent   potassium diformate  helps return to the essence of breeding and helps control the cost and quality of the pig industry. Biosecurity has become the access condition of today's pig industry. Potassium diformate has the following functions and functions to return the essence of pig farming to the breeding industry: (1) Adjust the palatability of feed and increase animal feed intake. (2) Improve the environment of the animal's digestive tract and lower the pH of the stomach and small intestine. (3) It has anti-bacterial and growth-promoting effects. The addition of potassium diformate can significantly reduce the content of anaerobic bacteria, Lactobacillus, Escherichia coli and Salmonella in each segment of the digestive tract. Improve the resistance of animals to diseases and reduce

The factory tells you food grade sodium tripolyphosphate/STPP requires heavy metal purification

Condiments, meat products, edible oil, dairy products, drinks, etc. are all necessities of daily life. Some food additives will be used in the production and processing process. The use of additives also makes people more concerned about "safety on the tip of the tongue".  Sodium tripolyphosphate/STPP  is widely used in food additives. Chongqing Chuandong Chemical Group will show you the main applications of sodium tripolyphosphate/STPP in the food industry: 1. Food grade sodium tripolyphosphate is used in meat products, fish sausage, ham, etc., which can improve the water holding capacity, increase the cohesiveness and prevent fat oxidation; 2. For fruit drinks and cool drinks, it can improve the juice yield, increase the viscosity and inhibit the decomposition of vitamin C. 3. It can prevent discoloration, increase viscosity, shorten fermentation period and adjust taste when used in soybean paste and soy sauce. 4. For ice cream, it can improve the expansion capacity, increa
