How is sodium hexametaphosphate used for water treatment?

Water treatment agent is necessary for the disposal of industrial water, domestic water and waste water. Sodium hexametaphosphate is a very widely used fine phosphate product. From the initial red treatment of water, with the development of industry, the application of sodium hexametaphosphate is more widely.

The principle of sodium hexametaphosphate used as a water treatment agent is to use the complexation of polyphosphate and phosphate generated by the hydrolysis of sodium hexametaphosphate to metal ions, so that most of the metal ions in the water are complexed into phosphate, thereby softens the water.

Sodium hexametaphosphate is easily soluble in water. The aqueous solution was alkaline, and the pH of the 1% aqueous solution was 9.7. It gradually hydrolyzes into phosphite in water and has a good ability to complex metal ions. It can complex with calcium, magnesium, iron and other metal ions to form soluble complexes. It can soften hard water. As an inorganic surfactant, it has the properties of a certain organic surfactant.

The sodium hexametaphosphate produced by Chuandong Chemical Group is a kind of thermal authentic phosphoric acid production, which has strict detection on the chain length of products, and is widely used in refractory additives, industrial water treatment, boiler soft water, detergent additives and other industrial additives.

Why is the unit price of food additive sodium tripolyphosphate higher than that of industrial grade? The manufacturer tells you

  Recently, the shortage of spot goods has intensified, which has entangled downstream manufacturers who want to purchase recently. Either they have not found a suitable manufacturer, or the price is not too expensive. Sodium tripolyphosphate, as a basic chemical material and related phosphorus containing products, plays an important role, and the relative price has also increased. Why is the unit price of   food additive sodium tripolyphosphate  higher than that of industrial grade? The manufacturer tells you. First of all, it can be seen literally that the content and related indicators of industrial grade sodium tripolyphosphate meet the national standard. The main raw material of sodium tripolyphosphate is phosphate rock. In the production process, the price of wet process is slightly lower, while the sodium tripolyphosphate produced by thermal process is relatively higher. The raw material of food additive sodium tripolyphosphate is based on the thermal process. As a...

Sodium cyanate for metal heat treatment increases wear resistance and corrosion resistance

For large castings, in the actual production, the deformation caused by heat treatment is very important to the subsequent process, and there are a lot of scrap due to excessive deformation. In order to reduce and control the deformation of large castings caused by heat treatment, we can optimize the process parameters of heat treatment, increase the isothermal stage, control the heating rate and the temperature of parts, and increase the quenching water temperature. Many manufacturers will buy  sodium cyanate  as heat treatment agent to reduce the deformation of heat treatment. In the process of heating and warming up, the surface temperature of the parts rises rapidly, the center temperature rises slowly, and there is thermal stress when there is a temperature difference between the surface and the center. The faster the heating speed, the greater the wall thickness of the parts, the greater the temperature difference and the greater the thermal stress produced. In the proce...

Can potassium diformate solve the problem of poultry and livestock diarrhea in the first winter after no resistance?

  As the cold air goes south and the temperature drops, many poultry and livestock in the north will begin to experience diarrhea after the beginning of winter. In the first winter after no resistance, various alternative anti-resistance programs ushered in a real test. Can   potassium diformate   solve the fundamental problem when the seasons are prone to stress reaction and diarrhea? Potassium diformate is not only highly acidic, but also slowly released in the digestive tract. It has high buffering capacity and can avoid excessive fluctuations in the acidity of the animal's gastrointestinal tract. 1. Improving protein digestibility and reducing protein levels are the basis for preventing diarrhea. There must be a basic common sense: the fast-growing varieties cultivated by modern genetic breeding have higher protein requirements than our actual dietary protein levels. In the long run, we need to increase protein levels instead of lowering protein levels. Low-protein di...
