What Is Sodium Hexametaphosphate and How Is It Made

Sodium phosphate is that the product with the biggest output and consumption in fine phosphorus chemicals products. Its technology development and market development are comparatively mature, primarily together with metal orthophosphate, sodium pyrophosphate, sodium salt and sodium metaphosphate. Among them, sodium hexametaphosphate is the most generally used useful phosphate within the market, which might be utilized in laundry, water treatment, food, mineral processing, scientific discipline and alternative industrial production. Sodium hexametaphosphate has varied formulations, reckoning on the character and characteristics of washing items, and is employed for emulsification, solubilization, wetting, penetration, dispersion, etcetera of surfactants, and its performance is supplemented by other organic or inorganic additives. It achieves the aim of improvement and removing grease and rust, similarly as disinfecting and protective the surface layer. the opposite is to use the spinoff properties of surfactants as industrial additives, akin to lubricating, softening, catalyzing, sterilizing, antistatic, plasticizing, defoaming, deodorizing, thickening, decondensing, rust-proof, waterproof, oil-proof , Anti-caking, flotation, part transfer catalysis, etc., utilized in the physical science industry, anti-system materials, polymerization, genetic engineering, biotechnology, etc., and has several applications that are endlessly developed.

Sodium hexametaphosphate is especially used in power stations, dispersants, warmth binders, boilers, soft water, wheeled vehicle and fertiliser plants, detergent additives, management or preservatives, cement hardening accelerators, cooling water treatment of antibiotic purifiers extremely effective softener. improvement agent for fiber business and bleaching and colouring industry. Used as a flotation agent within the ore processing industry. Used as a sedative in medicine. within the rock oil industry, it’s used for corrosion control of drilling pipes and for dominant the consistency of mud whereas drilling. It conjointly has sure uses in material printing, leather, paper, color film, soil analysis, radiochemistry, analytical chemistry and alternative departments.

Additionally to general anionic, nonionic, cationic, and amphoteric surfactants, metal hexametaphosphate has also developed useful surfactants, akin to reactive surfactants, to satisfy the necessities of emulsion chemical action within the production of artificial rubber, synthetic resins, and coatings. need. Additives, divisible surfactants, special surfactants containing silicon, fluorine, boron, etcetera are wide utilized in varied fields. Sodium hexametaphosphate is widely used, and its application has penetrated into the majority industrial fields, creating it troublesome to search out any business that has nothing to try and do with surfactants. In several industries, surfactants play the ultimate role and because the most significant additives, they’ll greatly improve the assembly process and products performance. it’s no exaggeration to say that surfactants are the foremost vital industry additives today, so that they are referred to as “industrial monosodium glutamate”.

How Is It Made

1.metal dioxyphosphate method. Neutralize the washing soda answer and acid at 80-100°C for {two} hours, the ensuing sodium dioxynitrate solution is evaporated, concentrated, cooled and crystallized to get sodium dihydrogen nitrate dihydrate, if heated to 110-230°C, two take away nasal water, still heat to get rid of structural water, then heat to 620°C for dehydration, the primary feeling of acid wrinkle correction ~ combined with six-hour cooling from 650°C to 60-80°C, the pill is crushed to get six faux bitter taste.

2. Phosphorus oxide method. The phosphorus pentoxide obtained by burning and oxidizing yellow phosphorus in an exceedingly dry air stream and cooling it’s mixed with washing soda in a sure proportion (Na20: P205=1~1.1). The mixed powder is indirectly heated in a black lead melting pot to form it dehydrated and fused, and therefore the ensuing metal hexametaphosphate soften is quenched and crushed to obtain industrial sodium hexametaphosphate finished products. Heat the chemical agent sodium dioxyphosphate to 700~900°C to melt. once the melt is totally clear and the internal bubbles disappear, it is quenched to 60~80°C to obtain a skinny glass product, that is metal hexametacarbonate. Heating the chemical agent sodium dihydrogen phosphate to 250°C and conclusion will obtain the chemical compound of sodium metaphosphate; heating to 650°C and quenching can obtain SHMP 68% powder.

3. phosphorous chemical compound method. once the yellow phosphorus is heated and melted, it’s sent to the reaction combustion furnace, and therefore the atomic number 8 within the dry air is employed for the oxidation combustion reaction to come up with the intermediate product phosphoric anhydride. once combining phosphoric anhydride and soda ash, it undergoes high-temperature polymerization, quenches and makes tablets to get flaky sodium hexametabasic acid; after crushing, it will get powdery metal hexametanitrate.
