Sodium tripolyphosphate can increase the decontamination ability of detergent

Detergent is a spare part in daily life and work. It plays an important role in healthy and clean environment and industrial production. The formation of all kinds of dirt is different. Detergent is used widely. However, detergent detergency is also formulated according to a certain formula. Sodium tripolyphosphate is an indispensable good adjuvant in detergent. The content of most detergents is 10-50%.

Its main functions can be summarized as follows.
1. Sodium tripolyphosphate mainly chelates metal ions in detergents. In daily washing water, it usually contains hard metal ions (mainly Ca2+, Mg2+). In the washing process, various metal ions form insoluble metal salts with the active substances in soap or detergent, which not only increases the consumption of detergent, but also makes the washed fabric have unpleasant dark grey. Sodium tripolyphosphate has excellent properties of chelating hard metal ions, thus eliminating the adverse effects of these metal ions.

2. Sodium tripolyphosphate can also improve the role of sol, emulsification and dispersion: dirt often contains human secretions (mainly proteins and lipids), but also contains sand and dust from the outside world. Sodium tripolyphosphate has the effects of swelling and solubilizing proteins, promoting emulsification of lipids and dispersing suspension of solid particles.

3. Buffering effect: Sodium tripolyphosphate has great alkaline buffering effect, keeping the pH value of washing solution at about 9.4, which is beneficial to the removal of acid fouling.

4. The function of preventing caking: Powdery synthetic detergent has hygroscopicity. If it is stored in a place with high humidity, caking will occur. The use of agglomerated detergents is extremely inconvenient. The hexahydrate formed by sodium tripolyphosphate absorbed water has the characteristics of dryness. When there is a large amount of sodium tripolyphosphate in the detergent formulation, it can prevent the caking phenomenon caused by moisture absorption and keep the dry and cool granularity of synthetic detergent.

So sodium tripolyphosphate is mainly used in detergent auxiliaries as an auxiliaries for synthetic detergents, soap synergists and preventing the precipitation and frosting of soap grease. It has strong emulsifying effect on lubricating oil and fat, and can be used to adjust the PH value of buffer soap.

Chuandong Chemical Group has different levels of sodium tripolyphosphate for different purposes.

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
