Sodium phosphate: tlhaloso, kopo, liphello 'meleng

Sodium phosphate (colloquial, e nepahetseng: phosphate ea sodium, orthophosphate, bone phosphate kapa Na ₃ PO ₄ ) ke letsoai le bohareng le hloekileng, le tsitsitseng le ho qhibiliha ntle le ho qhibiliha (mocheso oa likhato tse 250 le ka holimo). Ka metsing e qhibiliha, ho theha e matla alkaline seaplane.

Sodium phosphate e hlahisoa ke ketso ea alkali ka phosphoric acid (neutralization), le ho felloa ke metsi ha sodium hydrogenorthophosphates.

E sebelisoa e le li-emulsifiers le balaoli ba pH, hammoho le khahlanong le ho pata. Sodium ea phosphate e sebelisoa ke bahlahisi ba li-detergents. Haholo-holo hangata e sebelisoa ke triphosphate, e leng ka phofo e ka bang 50%. Ho nolofatsa metsi (ho felisa boima), ho sebelisoa dintho tse nang le metsi a mangata a etsang thepa e nang le metsoako (magnesium, calcium, barium, joalo-joalo). Phosphate ea sodium (theknoloji, tlas'a letšoao "B") e sebelisoa ha ho etsoa khalase, lipente, ho ntlafatsoa ha li-ores. Empa Na ₂ HPO ₄ • 12Н ₂ О (lijo, tlas'a letoto "A") li sebelisoa haholo-holo indastering ea lijo e le phofo ea ho baka. E ntlafatsa ts'ebetsong ea lebese le khutsitsoeng, li-cheeses, sausages. Sebelisa sodium phosphate bakeng sa electrophoresis (metsoako ea electrolytic) le ho nka lifoto (e le motsoako oa motlakase).

A re tšohleng li-orthophosphates ka ho qaqileng.

Tripolyphosphate ea sodium e hlahisoa tlasa mekhahlelo e 'meli: "A", "B". E tletse feela lijaneng tse khethehileng tsa MKR-1, e isoa ka likoloi tse khethehileng (tse khethehileng) tsa mineral. Sheba bophelo bo sa thibeloe.

Trisodium phosphate (sodium phosphate, trisubstituted) e sebelisoa liindastering tsa lijo, makhasi le pampiri, ka matla, ho hlahisa li-powders, liphaephe tsa ho hloekisa, lisebelisoa tsa ho hlatsoa liaparo le joaloka li-surfactants tsa tlhahiso ea samente. Ha ho cheka (indasteri ea oli) ho kenyeletsoa e le sebopeho sa polymer. Trisodium phosphate e fokotseha ka ho feletseng holim'a lisebelisoa leha e le life, kahoo ho hlokahala hore motho a phalle. Ka ntle ho litekanyo le litekanyo (kristale) le thepa ea alkaline, eseng e chesang. E ka sehlopheng sa bobeli sa kotsing ka tšusumetso meleng oa motho.

Potso e utloahalang: "Ka tšebeliso e ngata joalo, na sodium phosphate e senya 'mele ea rona?"

Antioxidant (ka mabitso e thathamisitsoe e le E-300 (le ho fihlela ho E-339) ho ka khoneha ho boloka mmala, qoba ponahalo ea bohale le ho sireletsa khahlanong le khothalletso ea mali. Sena se ka ba metsoako ea tlhaho (vithamine E, e tloaelehileng ho tsohle ascorbic acid) mme e entsoe ka lik'hemik'hale, Ka tlhaho, ha e hlahe.Ka kenngoa ho li-emulsions tse nang le oli (mohlala, mayonnaise, ketchup.) Ho phaella ho thepa ea emulsifier le stabilizer, Na ₃ PO ₄ ke moemeli oa ho boloka metsi, mochine o rarahaneng, o tsitsitseng .For mohlala, ho pheha ka mefuta e mengata (bakery, bakery) Ayne ke ea bohlokoa bakeng sa phahama e phahameng ea hlama, e nang le mohaho o motle le o bobebe.Hona ke moo tekanyo ea sekhahla pakeng tsa sodium bicarbonate le phosphoric acid letsoai e tlisa phello e lakatsehang.E-450 (SAPP, sodium pyrophosphate) e ratoa haholo. Ho phahamisa hlama (boholo ka ho bapisoa le li-analogues), e bolokiloeng ka mor'a ho baka, e kenyelletsoa ka li-muffins, bohobe, gingerbread, pizza, mahobe.Ka khothalletsoa hoo e batlang e le tlhahlobo efe kapa efe (tomoso e teteaneng, e shapuoa, lehlabathe le tšabehang Th).

Matlo a E-450, hammoho le matla a ho tlama khalsiamo a sebelisetsoa li-dairies. Li-pyrophosphates li itšetlehile haholo ka casin - e bula, e ruruha 'me e sebetsa e le emulsifier, e leng e loketseng ha u lokisetsa li-puddings, lihlahisoa tsa lebese, li-dessert. Lebese le nang le mollo, le fumanoang ka ho kha metsi, le lona le ke ke la etsa ntle le letsoalo la letsoai la DSP (dibasodium phosphate).

Lefapheng la nama, ka lebaka la li-emulsifiers tseo re li tšohlang, li eketsa haholo lihlahisoa tsa lihlahisoa tsa lihlahisoa ha li ntse li tsitsisa ho tsitsisa le ho ntlafatsa 'mala.
