Yintoni iTrisodium phosphate?

I-Trisodium phosphate, ekwaziwa ngokuba yi-'sodium orthophosphate'. Ifomyula yekhemikhali yi-Na3PO4 · 12H2O. Ayinambala okanye iikristale ezimhlophe ezimile okwenaliti okanye iipowder zekristale, kunye nendawo yokunyibilika eyi-73.4 ° C kwi-dodecahydrate. Inyibilikiswe emanzini, isisombululo samanzi sibonisa i-alkalinity enamandla ngenxa ye-hydrolysis enamandla yee-ion ze-phosphate (PO43-); Ayinyibiliki kwi-ethanol kunye ne-carbon disulfide. Ithambekele ekuqhekekeni nasekuguguleni emoyeni owomileyo, ivelisa i-sodium dihydrogen phosphate kunye ne-sodium bicarbonate. Phantse ibolile ngokupheleleyo ibe yi-disodium hydrogen phosphate kunye ne-sodium hydroxide emanzini. I-Trisodium phosphate yenye yeentlobo zemveliso ezibalulekileyo kushishino lwe-phosphate, esetyenziswa kakhulu kushishino lwanamhlanje lweekhemikhali, ezolimo kunye nokufuya izilwanyana, ipetroli, ukwenza amaphepha, izicoci, iiseramikhi kunye nezinye iindawo ngenxa yeempawu zayo ezikhethekileyo.

Isicelo

I-Trisodium phosphate yiarhente yokugcina umswakama kwishishini lokutya, isetyenziswa ekutyeni okusemathinini, kwiziselo zejusi yeziqhamo, kwiimveliso zobisi, kwiimveliso zenyama, kwitshizi, nakwiziselo. Isetyenziswa njengesithambisi samanzi kunye nesicoci kwimizi-mveliso efana neekhemikhali, ilaphu, ukuprinta kunye nokufaka idayi, ukwenza iphepha, kunye nokuvelisa umbane, iarhente yokuthintela ukukala kwibhoyila, isithambisi samanzi kwidayi yephepha, iarhente yokubopha i-pH kwizincamathelisi ezisetyenziswa kwimveliso yephepha le-wax, iarhente yokulungisa ngexesha lokuprinta kunye nokufaka idayi, isithambisi sesilika seempahla, kunye nearhente yokulwa nokuqhekeka kwimigca yemveliso. Ishishini le-Metallurgical lisetyenziswa njengearhente yokususa amafutha kunye nokucoca iikhemikhali, kwaye njengesixhobo esibalaseleyo kwizisombululo zophuhliso lweefoto. Iiarhente zokucoca amazinyo kunye neesepha zokucoca iibhotile. Isicoci sobisi lwerabha. Isicoci sejusi yeswekile.
