The manufacturer tells you the solubility of sodium hexametaphosphate technical grade is related to temperature and PH

Chemical formula of sodium hexametaphosphate: Na6P6O18. It is a polar inorganic compound, soluble in water, with a relative density of 2.484 and a melting point of 616 ℃ (decomposition). The solubility in water is large, but slow.


Phosphorus oxide and its hydrate have relatively strong water absorption, and become sticky after moisture absorption, so it is easy to deliquesce in the air. In general, with the increase of temperature, the solubility will increase (with some exceptions, such as calcium hydroxide).


Therefore, the solubility of sodium hexametaphosphate technical grade is greatly affected by temperature. At 20 ℃, its solubility is 963.2g, while at 80 ℃, its solubility is as high as 1744g/kg (equivalent to two kilograms of product dissolved in one kilogram of water). However, its dissolution rate is slow, its aqueous solution is acid, and it is easy to hydrolyze to orthophosphate in warm water or acid-base solution. The hydrolysis process is irreversible and the hydrolysis process is irreversible Temperature is related to temperature and PH value.


Sodium hexametaphosphate technical grade has a certain process because it can be hydrolyzed to phosphite and orthophosphate when dissolved in water. It is precisely because of this process that it has better properties than other phosphates when used as softening water and dispersant.


The sodium hexametaphosphate technical grade produced by Chongqing Chuandong Chemical Group takes the yellow phosphorus produced from the phosphate rock of our own fine phosphate mine as the raw material, and then the genuine thermal process phosphoric acid produced by the thermal process is used as the raw material, with uniform particles, less impurities, better flow rate and less consumption. It is widely used in water treatment, detergent auxiliaries, flotation agents, refractory materials, important addition of ceramics, efficient softener for cooling water treatment of boilers and fertilizer plants, etc.

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
