How much water do we need to add when dissolving sodium hexametaphosphate?

 In industry, sodium hexametaphosphate is widely used, including cleaning agents, refractory materials, mineral processing, ceramics, and industrial water treatment. In most of these industries, when applying sodium hexametaphosphate, it needs to be dissolved before being added. As the manufacturer of sodium hexametaphosphate, it is often asked how much water is needed to dissolve sodium hexametaphosphate?


Sodium hexametaphosphate is soluble in water but insoluble in organic solvents. When adding it, the composition of the other raw materials involved and the desired effect should be considered. For example, most of them will use the chelating ability and dispersing power of sodium hexametaphosphate to metal ions, and the water content, pH, temperature and other factors have to be considered in the production. These parameters can only be calculated by technicians involved in actual production.


The molecular weight of sodium hexametaphosphate is 611.82, the relative density is 2.484, and it is easily soluble in water. The theoretical basis is that it dissolves 973.2g per liter of water at 20°C and 1744g per liter of water at 80°C. The pH value of 10g/L aqueous solution is 5.8-7.0, the instantaneous solubility, saturated solubility, hydrolysis process, heating crystallization, optical and electrical properties, viscosity, density and surface tension of sodium hexametaphosphate, and even colloidal properties and hygroscopicity.


The main factor of the water required to dissolve sodium hexametaphosphate is its instantaneous solubility and saturated solubility.

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
