Ingcaciso yeMveliso:
Iasidi yePhosphoric yiasidi eqhelekileyo ye-inorganic kwaye iphakathi ukuya kwiasidi eyomeleleyo.I-asidi yayo ibuthathaka kunee-asidi ezomeleleyo ezifana ne-asidi ye-sulfuric, i-hydrochloric acid kunye ne-nitric acid, kodwa yomelele kune-acids ebuthakathaka njenge-acetic acid, i-boric acid kunye ne-carbonic acid.Iasidi yephosphoric idibana nesodium carbonate kwi Chemicalbook eyahlukeneyo pH ukuvelisa iityuwa zeasidi ezahlukeneyo.Inokuvuselela ulusu ukuba lubangele ukudumba kwaye lutshabalalise izicubu zezihlunu.I-asidi ye-phosphoric egxininisiweyo inempembelelo ephazamisayo xa ishushu kwi-porcelain.I-hygroscopic, yigcine ivaliwe.
Isicelo:
(1) Isetyenziswa ikakhulu kwishishini lephosphate, i-electroplating, ishishini lokugulisa, ishishini leswekile, isichumiso esiyimbumba njalo njalo.Kwishishini lokutya njenge-acidifier, i-yeast izondlo, njl.
(2)Ikakhulu isetyenziswa njenge-catalyst ye-ethylene hydration ukuvelisa i-ethanol, i-phosphate yococeko oluphezulu, ukuveliswa kwamachiza, i-reagent yekhemikhali.
3
(4) Ekuveliseni ityhubhu ye-silicon yendiza kunye neesekethe ezidibeneyo, ifilimu ye-aluminium esetyenziswa ngokuqhelekileyo kwi-electrode lead, imfuno ye-photolithography yefilimu ye-aluminium, usebenzisa i-phosphoric acid njenge-acidic yokucoca i-corrosive.Inokuqulunqwa nge-acetic acid.
(5)Ingasetyenziswa njenge-agent emuncu kunye nesondlo segwele.Inokusetyenziswa njenge-ejenti emuncu kwi-seasonings, iimpahla ezinkonkxiweyo, kunye neziselo ezihlaziyayo.Isetyenziswa njengegwele lomthombo wezondlo xa kusenziwa utywala ukuthintela ukwanda kweebhaktheriya ezilahlekileyo.
(6)Iasidi yephosphoric emanzi isetyenziswa ikakhulu ukwenza iiphosphates ezahlukahlukeneyo, ezifana nephosphates ammonium, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphates, njl. kunye ne-condensed phosphates.I-asidi ye-phosphoric ecolisisiweyo isetyenziselwa ukwenza i-calcium phosphate yokutya.Isetyenziselwa unyango lwe-metal surface phosphating, isisombululo se-electrolytic polishing kunye nesisombululo sokupholisa imichiza yokupholisa iimveliso ze-aluminium.
(7)Ushishino lwamachiza okwenziwa kwesodium glycerophosphate, iphosphate yentsimbi, njl. njl., kodwa kunye nokwenziwa kwephosphate ye-zinc njengengcina yamazinyo yeChemicalbook yamazinyo.Isetyenziswe njenge-catalyst ye-phenolic resin condensation, idayi kunye ne-intermediates yokuvelisa i-desiccant.Umzi-mveliso woshicilelo wokulungiselela ukucima amabala epleyiti yoshicilelo yombala we-offset kwisisombululo sokucoca.Ikwasetyenziselwa ukwenza ulwelo lokumithisa imicinga yematshisi.Imboni ye-Metallological yokuvelisa udaka lwe-phosphoric acid refractory, ukuphucula ubomi be-steelmaking furnace.Yeyona arhente yokuqinisa intlama yerabha kunye nemathiriyeli ekrwada yokuvelisa isibophelelo se-inorganic.Isetyenziswa kwishishini lepeyinti njengepeyinti ye-antirust yentsimbi.
(8) Ukuzimisela kwe-chromium, i-nickel, ukubunjwa kwe-vanadium kwintsimbi, ukuthintela ukurusa kwesinyithi, i-rubber coagulant, ukuzimisela kwe-nitrogen engeyona iprotheni kwi-serum, i-cholesterol epheleleyo kunye ne-glucose yegazi kunye nokunye.I-crystallized phosphoric acid isetyenziswa kakhulu kwi-microelectronics, iibhetri ezinamandla amakhulu, iglasi ye-laser kunye nezinye iinkqubo zokuvelisa, njenge-catalyst ephezulu, izixhobo zonyango.
