The nations as the world's water consumption sharply to add, also all kinds of environmental statutes heels (water purification method) to formulate, severe day by day and so on all kinds of efficient water disposal reagents to improve soon.Water treatment agent is industrial water, water, waste water disposal in the process of the necessary chemicals, after using these chemicals, can make the water reach the necessary quality requirements.Phosphate sodium hexametaphosphate is very common in potions, corrosion in the water treatment effect is better.
Water treatment agent first effect is moderate scale and the composition of the sludge, reduce foam, cutting materials contact with the water erosion, remove the suspended solid in the water, and toxic substances, deodorant decoloring, softened water, etc.
Water treatment reagents can be roughly divided into three categories:
One, sewage treatment agent
Second, the industrial circulating water treatment agent
Three, the oil-water separating agent
Commonly used water treatment agents are: the scale inhibitor, corrosion inhibitor, algae fungicidal (water treatment disinfectant), cleaning agents, sticky mud stripping agent, flocculant, coagulant, dispersing agent, such as water treatment agent, sodium hexametaphosphate is also a kind of water treatment.
Sodium hexametaphosphate is really a lot of is used in water treatment, is used to overcome the phenomenon of "red water", before slowly since the development of circulating water treatment, food, mining, drilling, textile printing and dyeing, the application of refractory materials and many other convenient.
Sodium hexametaphosphate is also an important industrial raw materials, water treatment, soluble in water.Alkaline aqueous solution, 1% aqueous solution PH 9.7, has the good complexing ability of metal ions.With calcium, magnesium, iron and other metal ions complexation, generate soluble complex.Gradually hydrolyzed to the phosphate in the water, but in the circulating water system is quite harsh operating conditions, a single phosphate treatment often can't meet the demand, the use will have more corrosion and scale inhibition effect of combined use of two or more agents.
