I-Phosphoric acid 85%
Iphrofayili yomkhiqizo
I-Phosphoric acid, eyaziwa nangokuthi i-orthophosphoric acid, iyi-asidi ye-inorganic evame ukusetshenziswa ezimbonini ezihlukahlukene. Ine-asidi eqinile ngokumaphakathi, ifomula yayo yamakhemikhali yi-H3PO4, futhi isisindo sayo samangqamuzana ngu-97.995. Ngokungafani namanye ama-acids aguquguqukayo, i-phosphoric acid izinzile futhi ayibhidliki kalula, okwenza kube ukukhetha okuthembekile kwezinhlelo zokusebenza ezihlukahlukene. Nakuba i-phosphoric acid ingaqinile njenge-hydrochloric, sulfuric, noma i-nitric acid, inamandla kune-acetic ne-boric acid. Ngaphezu kwalokho, le acid inezakhiwo ezijwayelekile ze-asidi futhi isebenza njenge-asidi ye-tribasic ebuthakathaka. Kuyaqapheleka ukuthi i-phosphoric acid iyi-hygroscopic futhi imunca kalula umswakama ovela emoyeni. Ngaphezu kwalokho, inamandla okuguqula i-pyrophosphoric acid lapho ishisa, futhi ukulahlekelwa kwamanzi okulandelayo kungawuguqula ku-metaphosphoric acid.

Ukusetshenziswa:
Ukuguquguquka kwe-phosphoric acid kuyenza ibaluleke kakhulu ezimbonini ezahlukahlukene, ikakhulukazi ukukhiqizwa kwemithi, ukudla kanye nomanyolo. Emkhakheni wemithi, isetshenziswa kabanzi njenge-ejenti elwa nokugqwala futhi njengesithako ezinqubo zamazinyo nezamathambo. Njengesengezo sokudla, kuqinisekisa ikhwalithi yomkhiqizo ozinzile. I-Phosphoric acid iphinde isetshenziswe njenge-etchant ku-electrochemical impedance spectroscopy (EDIC) nanjenge-electrolyte, i-flux ne-disperant ezinqubweni ezihlukahlukene zezimboni. Izakhiwo zayo ezonakalisayo ziyenza ibe impahla eluhlaza esebenzayo yabahlanzi bezimboni, kuyilapho kwezolimo i-phosphoric acid iyingxenye ebalulekile kamanyolo. Ngaphezu kwalokho, iyinhlanganisela ebalulekile emikhiqizweni yokuhlanza yasendlini futhi isetshenziswa njenge-ejenti yamakhemikhali.
Ukufingqa, i-phosphoric acid iyinhlanganisela ebalulekile yemisebenzi eminingi esetshenziswa kabanzi ezimbonini ezahlukahlukene. Imvelo yayo ezinzile futhi engaguquguquki, ehlanganiswe ne-asidi yayo emaphakathi, yenza kube yisinqumo sokuqala sezinhlelo zokusebenza eziningi. Ukusetshenziswa okubanzi kwe-Phosphoric acid, kusukela kwezemithi kuye kwezithasiselo zokudla, kusukela ezinqubweni zamazinyo kuya ekukhiqizeni umanyolo, kufakazela ukubaluleka kwayo ekukhiqizeni nasekuphileni kwansuku zonke. Kungakhathaliseki ukuthi iyi-caustic, i-electrolyte noma isithako sokuhlanza, le asidi ifakazele ukusebenza kwayo nokwethembeka. Ngobubanzi bayo bezinhlelo zokusebenza kanye nezakhiwo ezizuzisayo, i-phosphoric acid iyimpahla ebalulekile kuzo zonke izimboni eziningana.
