Why is industrial grade sodium tripolyphosphate also a multifunctional ceramic additive?

 Whether in house decoration, industrial production or tableware common at home, we can see the figure of ceramic materials. Ceramic additives have important practical significance to reduce energy consumption, improve process performance, reduce production cost and improve production efficiency. With so many additives, why is industrial grade sodium tripolyphosphate also a multifunctional ceramic additive?


Sodium tripolyphosphate, also known as water reducing agent, degumming agent and coagulant, is mainly used to improve the fluidity of ceramic blank and glaze slurry, so that the slurry has the least water content, better fluidity, no flocculation and sedimentation, and is easy to operate. It is applied in various process.


Dispersion

The system formed by the dispersion of solid particles in liquid medium should belong to the category of colloid. The system is thermodynamically unstable and the particles tend to agglomerate. At this time, the addition of ceramic additive sodium tripolyphosphate prevents the agglomeration of ceramic particles by interacting with the surface of ceramic particles, which can prevent the agglomeration of particles and make the components of raw materials evenly dispersed in the liquid medium.


Suspension stabilization

In fact, the suspension stability mechanism of sodium tripolyphosphate is similar to that of dispersion. Some solid particles insoluble in water or slightly soluble in water can be evenly dispersed in the liquid medium with the help of sodium tripolyphosphate to form a fine, highly suspended and mobile stable liquid-solid system to improve the suspension stability of slurry.


Water reducing effect

Sodium tripolyphosphate is a water reducing agent commonly used in ceramic additives. The function of sodium tripolyphosphate is to improve the slurry performance and make the slurry have appropriate viscosity, good fluidity and high solid content under the condition of low moisture, so as to facilitate operation and achieve the purpose of energy saving and consumption reduction.


Ceramic additives are indispensable in the preparation of ceramic raw materials, from the preparation of powder, slurry and plastic embryo, to molding, drying, sintering and other processes. The application of sodium tripolyphosphate is also an important additive directly related to the improvement of product quality, performance, variety and process conditions.

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
