Phosphoric acid 85%
Boemo ba sehlahisoa
Phosphoric acid, eo hape e tsejoang e le orthophosphoric acid, ke asiti ea inorganic e sebelisoang haholo liindastering tse fapaneng. E na le asiti e matla ka mokhoa o itekanetseng, foromo ea eona ea lik'hemik'hale ke H3PO4, 'me boima ba eona ba molek'hule ke 97.995. Ho fapana le li-acid tse ling tse sa tsitsang, phosphoric acid e tsitsitse ebile ha e robehe habonolo, e etsa hore e be khetho e tšepahalang bakeng sa mefuta e fapaneng ea likopo. Le hoja asiti ea phosphoric e se matla joaloka hydrochloric, sulfuric, kapa nitric acids, e matla ho feta acetic le boric acid. Ho feta moo, asiti ena e na le litšobotsi tse akaretsang tsa asiti mme e sebetsa joalo ka asiti e fokolang ea tribasic. Ho bohlokoa ho hlokomela hore asiti ea phosphoric ke hygroscopic mme e monya mongobo habonolo moeeng. Ho phaella moo, e na le monyetla oa ho fetola pyrophosphoric acid ha e futhumala, 'me tahlehelo e latelang ea metsi e ka e fetolela ho metaphosphoric acid.

Tšebeliso:
Ho feto-fetoha ha phosphoric acid ho etsa hore e be ea bohlokoa haholo liindastering tse fapaneng, haholo tlhahiso ea meriana, lijo le manyolo. Lefapheng la meriana, e sebelisoa haholo e le moemeli oa anti-rust hape e le motsoako oa mekhoa ea meno le ea masapo. Joaloka motsoako oa lijo, e tiisa boleng bo tsitsitseng ba sehlahisoa. Phosphoric acid e boetse e sebelisoa e le etchant ho electrochemical impedance spectroscopy (EDIC) hape e le electrolyte, flux le dispersant lits'ebetsong tse fapaneng tsa indasteri. Mehaho ea eona e senyang e etsa hore e be thepa e tala e sebetsang bakeng sa bahloekisi ba indasteri, ha temong ea phosphoric acid e le karolo ea bohlokoa ea manyolo. Ho feta moo, ke motsoako oa bohlokoa lihlahisoa tsa ho hloekisa malapeng 'me o sebelisoa e le moemeli oa lik'hemik'hale.
Ho akaretsa, asiti ea phosphoric ke motsoako oa bohlokoa haholo oa mesebetsi e mengata e sebelisoang haholo liindastering tse fapaneng. Sebopeho sa eona se tsitsitseng le se sa tsitsang, se kopantsoeng le acidity ea sona e itekanetseng, se etsa hore e be khetho ea pele bakeng sa likopo tse ngata. Phosphoric acid e mengata e fapaneng ea tšebeliso, ho tloha ho meriana ho ea ho li-additives tsa lijo, ho tloha lits'ebetsong tsa meno ho ea ho tlhahiso ea manyolo, e paka bohlokoa ba eona tlhahisong le bophelong ba letsatsi le letsatsi. Ebang ke motsoako oa caustic, electrolyte kapa motsoako oa ho hloekisa, acid ena e ipakile e sebetsa hantle le ho tšepahala. Ka mefuta e mengata e fapaneng ea ts'ebeliso le thepa ea bohlokoa, asiti ea phosphoric ke letlotlo la bohlokoa ho liindasteri tse 'maloa.
