Phosphoric acid ndi asidi wamba wachilengedwe ndipo ndi wapakati mpaka asidi wamphamvu.Chidulo chake ndi chofooka kuposa ma asidi amphamvu monga sulfuric acid, hydrochloric acid ndi nitric acid, koma amphamvu kuposa asidi ofooka monga acetic acid, boric acid ndi carbonic acid.Phosphoric acid imakhudzidwa ndi sodium carbonate ku Chemicalbook yosiyana pH kupanga mchere wosiyanasiyana wa asidi.Ikhoza kuyambitsa khungu kuti lipangitse kutupa ndikuwononga minofu ya minofu.Zoyikira phosphoric acid zimakhala ndi erosive zotsatira zikatenthedwa mu porcelain.Ndi hygroscopic, isungeni yosindikizidwa.
Ntchito:
(1) Amagwiritsidwa ntchito kwambiri m'makampani a phosphate, electroplating, kupukuta mafakitale, mafakitale a shuga, feteleza wamagulu ndi zina zotero.M'makampani azakudya monga acidifier, mchere wa yisiti, etc..
(2) Amagwiritsidwa ntchito kwambiri ngati chothandizira kuti ethylene hydration ipange Mowa, phosphorous yoyera, kupanga mankhwala, reagent yamankhwala.
(3) Amagwiritsidwa ntchito makamaka popanga feteleza wamankhwala, zotsukira, zakudya ndi zakudya zowonjezera, zoletsa moto ndi ma phosphates osiyanasiyana.
(4) Popanga chubu la ndege la silikoni ndi mabwalo ophatikizika, omwe amagwiritsidwa ntchito kwambiri filimu ya aluminiyamu yotsogolera ma elekitirodi, kufunikira kwa filimu ya aluminiyamu yojambula zithunzi, kugwiritsa ntchito phosphoric acid ngati zowononga zowononga acidic.Itha kupangidwa ndi acetic acid.
(5) Itha kugwiritsidwa ntchito ngati wowawasa ndi mchere wa yisiti.Itha kugwiritsidwa ntchito ngati zokometsera zokometsera, zinthu zamzitini, ndi zakumwa zotsitsimula.Amagwiritsidwa ntchito ngati gwero lazakudya za yisiti popanga moŵa pofuna kupewa kufalikira kwa mabakiteriya osokera.
(6) Chonyowa asidi phosphoric zimagwiritsa ntchito kupanga phosphates zosiyanasiyana, monga ammonium mankwala, potaziyamu dihydrogen mankwala, disodium hydrogen mankwala, trisodium mankwala, etc. ndi phosphates condensed.Mafuta a phosphoric acid amagwiritsidwa ntchito kupanga calcium phosphate ku chakudya.Amagwiritsidwa ntchito pochiza zitsulo za phosphating, njira yopangira ma electrolytic polishing solution ndi njira yopukutira mankhwala popangira zinthu zotayidwa.
(7) Mankhwala makampani kupanga sodium glycerophosphate, chitsulo mankwala, etc., komanso kupanga nthaka mankwala ngati mano Chemicalbook mano kudzaza zomatira.Amagwiritsidwa ntchito ngati chothandizira pa phenolic resin condensation, utoto ndi intermediates kupanga desiccant.Makampani osindikizira akukonzekera kupukuta madontho osindikizira amtundu wa offset panjira yoyeretsera.Amagwiritsidwanso ntchito popanga zamadzimadzi zothirira pamitengo ya machesi.Metallurgical makampani kupanga phosphoric asidi refractory matope, kusintha moyo wa steelmaking ng'anjo.Ndiwolimbitsa mphamvu ya phala la rabara ndi zinthu zopangira kupanga binder.Amagwiritsidwa ntchito m'makampani opaka utoto ngati utoto wotsutsa zitsulo.
(8) Kutsimikiza kwa chromium, nickel, vanadium mu chitsulo, kupewa dzimbiri lachitsulo, mphira coagulant, kutsimikiza kwa nayitrogeni wopanda mapuloteni mu seramu, cholesterol yonse ndi shuga wamagazi onse ndi zina zotero.Crystallized phosphoric acid makamaka ntchito microelectronics, mkulu-mphamvu mabatire, laser galasi ndi njira zina kupanga, monga mkulu-chiyero chothandizira, zipangizo zachipatala.
