Technical grade sodium hexametaphosphate is a common additive in refractories

 With the development of refractories industry and social progress, refractories with slow construction speed are gradually replaced, and the amount of unshaped refractories is increasing in the metallurgical industry. The largest amount of sodium hexametaphosphate technical grade used in unshaped refractories is castable, followed by spray coating.


The sodium hexametaphosphate technical grade is mainly used in the refractory castables, refractory plastics and refractory slurries with cement as binder, which usually plays a role of reducing water; according to the needs of preparing different kinds of amorphous refractories, the use of industrial sodium hexametaphosphate in the additives of the amorphous refractories is also different.


Therefore, the sodium hexametaphosphate technical grade produced by Chongqing Chuandong Chemical Group is a new refractory with good performance in phosphate. It has good thermal shock stability, high compressive strength, strong resistance to slag corrosion and impact, high load softening temperature and chemical stability.

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
