What is the detergency of sodium tripolyphosphate in cleaning aids? The manufacturer in China tells you

Detergent aids are commonly used in various cleaning products, whether they are household washing products or industrial washing products. Adding detergent additives can improve the ability of various components in the detergent to penetrate clothing fibers, as well as further clean other surfaces and materials. Sodium tripolyphosphate is an additive with this excellent performance.


Washing aid is actually a comprehensive effect of multiple actions such as softening water, dispersing, emulsifying, anti redeposition, and PH buffering. Sodium tripolyphosphate not only has excellent cleaning aid, but also has strong decontamination ability without detergent. When it is compatible with surfactants, its detergency greatly exceeds the simple superposition of the two, which has a synergistic effect on surfactants.


Therefore, in most factories, sodium tripolyphosphate is used in multiple fields in the production of detergent auxiliaries. What is the principle of adding sodium tripolyphosphate to detergent?


There are many types of detergent auxiliaries, of which sodium tripolyphosphate is one, and its components play a very important role.


One is the chelation of heavy metal ions: Heavy metal ions in water are used to combine with detergent molecules during the washing process to form insoluble metal salts, reducing the washing ability or even completely losing their effect. Therefore, it is necessary to add substances in the detergent that can make the heavy metal ions contained in the washing water harmless.


Sodium tripolyphosphate is an additive with this excellent performance and has a strong chelating effect on heavy metal ions, which can seal them up and eliminate their adverse effects on washing. In addition, it can also capture various metal components contained in the dirt and play a role in dissociating the dirt during the washing process.


Secondly, it has the effect of degumming, emulsifying, and dispersing dirt: sodium tripolyphosphate has the effect of expanding and solubilizing proteins in dirt, thereby achieving degumming effect; Promoting emulsification of fat; It has a dispersing effect on solid dirt.


Thirdly, it has a preventive effect on detergents from clumping: sodium tripolyphosphate can keep detergents in a dry and granular state, and has the effect of preventing clumping due to water absorption. In addition, sodium tripolyphosphate also has an alkaline buffer effect that is conducive to the removal of acidic dirt.

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
