What role does industrial grade sodium tripolyphosphate play in ceramic process production?

 Exquisite ceramics are pleasing to the eye. Ceramic products are also standing in people's life, adding color to daily life. Pottery is made of clay with high viscosity and strong plasticity. It is opaque, has fine pores and weak water absorption, and the sound of hitting is turbid. Porcelain is made of clay, feldspar and quartz. It is translucent, non absorbent, corrosion-resistant, hard and tight, and crisp. So what role does industrial grade sodium tripolyphosphate play in the production process of ceramics, from the initial old clay to exquisite ceramic technology?


What role does sodium tripolyphosphate play in ceramic production?

1. Sodium tripolyphosphate can be widely used in mud making, slurry grinding and process (including barren raw materials).

2, sodium tripolyphosphate can make mud good fluidity and low viscosity to meet the requirements of spray or mold filling and leveling.

3. Sodium tripolyphosphate can reduce the water content of slurry, prevent shrinkage and deformation cracking during green body drying, and reduce the damage rate of green body.

4. Sodium tripolyphosphate can make the mud stable and of good quality.

5. Sodium tripolyphosphate can lubricate and aid grinding between slurry particles, shorten ball milling time, improve work efficiency and save energy consumption.

6. Sodium tripolyphosphate has the advantages of convenient feeding and accurate measurement, which can reduce labor intensity and greatly reduce production cost.


Therefore, sodium tripolyphosphate is also called water reducing agent, degumming agent and coagulant in ceramic production. Its function is mainly to improve the fluidity of ceramic blank and glaze slurry, so as to minimize the water content of slurry, improve the fluidity, do not flocculate and precipitate, and facilitate operation.

What role will industrial grade sodium hexametaphosphate manufacturers play in the future coating industry?

图片
The keyword in 2019 is environmental protection and safety. In 2020, environmental protection and safety hurricanes will be more violent. In the manufacturing industry, whether it's packaging, printing, furniture, shipping industry or the phosphate raw material manufacturing enterprises like Chongqing Chuandong Chemical Group that produce  industrial grade sodium hexametaphosphate , it's a good choice to withstand the environmental storm and the obvious environmental protection conditions of the enterprise itself. Take the paint industry for example, the current paint market can be found that although the domestic paint industry has achieved rapid development and formed a certain industry scale, but in the domestic high-end paint market, the domestic paint brands or enterprises are indeed few, and the domestic high-end paint market is still occupied by most of the market share of imported brands. In fact, all industries need to use coatings, and environmental protection coating

What is the use of calcium formate industrial grade in construction? The manufacturer tells you

  With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use.   Calcium formate industrial grade   is a good early strength agent. Although both calcium formate and calcium chloride are calcium salts, relatively speaking, the performance of calcium formate is more stable. Because the formic acid in calcium formate is a weak acid. The solution will be weakly alkaline during the hydrolysis in the aqueous solution. It can be widely used in mortar. Calcium formate industrial grade is now a newly developed low temperature early strength accelerator in China, which has been widely used in various construction cement mortars. The earliest known and used chlorine salt early strength agent in construction, but the chloride salt early str

The effect of calcium supplement with feed grade calcium formate is good when crops are short of calcium

  Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use   feed grade calcium formate   to supplement calcium? The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease. No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what sho
