Incazelo Yomkhiqizo

I-superphosphate ephindwe kathathu (TSP) yenziwe nge-concentrate phosphoric acid kanye netshe le-ground phosphate. Kungumanyolo we-phosphate oncibilikayo emanzini, futhi osetshenziswa kabanzi enhlabathini eminingi. Ingasetshenziselwa ukuba umanyolo oyisisekelo, umanyolo owengeziwe, umanyolo wamagciwane kanye nezinto ezingavuthiwe zokukhiqiza umanyolo ohlanganisiwe.

Isingeniso

I-TSP ingumanyolo we-phosphate oncibilika kakhulu emanzini, futhi okuqukethwe kwawo kwe-phosphorus okusebenzayo kuwu-2.5 kuya ku-3.0 izikhathi ze-calcium evamile (SSP). Umkhiqizo ungasetshenziswa njengomanyolo wesisekelo, ukugqoka okuphezulu, umanyolo wembewu kanye nezinto ezingavuthiwe zokukhiqiza umanyolo oyinhlanganisela; esetshenziswa kakhulu elayisi, ukolweni, ummbila, amabele, ukotini, izithelo, imifino kanye nezinye izitshalo zokudla kanye nezitshalo zomnotho; esetshenziswa kabanzi enhlabathini ebomvu kanye nenhlabathi ephuzi , Inhlabathi ensundu, inhlabathi ephuzi ye-fluvo-aquic, inhlabathi emnyama, inhlabathi yesinamoni, inhlabathi ensomi, inhlabathi ye-albic nezinye izimfanelo zomhlabathi.

Inqubo Yokukhiqiza

Yamukelwe indlela yamakhemikhali yendabuko (indlela ye-Den) yokukhiqiza.
I-Phosphate rock powder (slurry) ihlangana ne-sulfuric acid ngokuhlukana okuqinile okuwuketshezi ukuze kutholakale inqubo emanzi exuba i-phosphoric acid. Ngemuva kokugxila, i-phosphoric acid egxilile itholakala. I-phosphoric acid egxilile kanye ne-phosphate rock powder kuxutshwe (kwakhiwe ngamakhemikhali), futhi izinto zokusabela ziyapakishwa futhi zivuthwe, zihlutshiwe, zomiswe, zihlungwe, (uma kunesidingo, iphakheji lokulwa namakhekhe), bese lipholiswa ukuze kutholwe umkhiqizo.

Ukucaciswa

Isingeniso kuCalcium Superphosphate

I-Superphosphate, eyaziwa nangokuthi i-superphosphate evamile, iwumanyolo we-phosphate olungiselelwe ngokuqondile ngokubola idwala le-phosphate ne-sulfuric acid. Izingxenye eziwusizo eziyinhloko yi-calcium dihydrogen phosphate hydrate Ca (H2PO4) 2 · H2O kanye nenani elincane le-phosphoric acid yamahhala, kanye ne-anhydrous calcium sulfate (iwusizo enhlabathini entula isibabule). I-calcium superphosphate iqukethe i-14% ~ 20% esebenzayo ye-P2O5 (80% ~ 95% yayo encibilika emanzini), okungomanyolo we-phosphate oncibilika ngokushesha osebenza emanzini. Impushana empunga noma empunga (noma izinhlayiya) ingasetshenziswa ngokuqondile njengomanyolo we-phosphate. Ingasetshenziswa futhi njengesithako sokwenza umanyolo ohlanganisiwe.

Umanyolo ongenambala noma ompunga okhanyayo (noma oyimpuphu). I-Solubility iningi lazo lincibilika kalula emanzini, futhi ezimbalwa azincibiliki emanzini futhi zincibilika kalula ku-2% citric acid (isixazululo se-citric acid).
