Product Description:
Phosphoric acid yog ib hom inorganic acid thiab yog nruab nrab rau cov kua qaub.Nws cov acidity tsis muaj zog dua li cov kua qaub uas muaj zog xws li sulfuric acid, hydrochloric acid thiab nitric acid, tab sis muaj zog dua li cov acids tsis muaj zog xws li acetic acid, boric acid thiab carbonic acid.Phosphoric acid reacts nrog sodium carbonate ntawm Chemicalbook txawv pH los tsim cov kua qaub sib txawv.Nws tuaj yeem ua rau cov tawv nqaij ua rau mob thiab ua kom puas cov leeg nqaij.Concentrated phosphoric acid muaj cov nyhuv erosive thaum rhuab hauv cov plooj (porcelain).Nws yog hygroscopic, khaws nws kaw.
Daim ntawv thov:
(1) Feem ntau siv hauv kev lag luam phosphate, electroplating, polishing kev lag luam, kev lag luam qab zib, composite fertilizer thiab lwm yam.Hauv kev lag luam khoom noj xws li acidifier, poov xab nutrient, thiab lwm yam.
(2) Feem ntau yog siv los ua catalyst rau ethylene hydration los tsim ethanol, siab purity phosphate, kev tsim tshuaj, tshuaj reagent.
(3) Feem ntau yog siv rau hauv kev tsim cov tshuaj chiv, tshuaj detergents, zaub mov thiab pub additives, nplaim retardants thiab ntau yam phosphates.
(4) Hauv kev tsim cov silicon dav hlau raj thiab kev sib txuas ua ke, feem ntau siv txhuas zaj duab xis rau electrode leads, xav tau photolithography ntawm aluminium zaj duab xis, siv phosphoric acid ua acidic tu corrosive.Nws tuaj yeem tsim nrog acetic acid.
(5) tuaj yeem siv los ua tus neeg sawv cev thiab cov poov xab.Nws tuaj yeem siv los ua tus neeg sawv cev souring rau seasonings, cov khoom kaus poom, thiab cov dej qab zib.Siv raws li poov tshuaj nutrient qhov chaw nyob rau hauv brewing los tiv thaiv propagation ntawm stray kab mob.
(6) Cov phosphoric acid ntub dej yog siv los ua ntau yam phosphates, xws li ammonium phosphate, potassium dihydrogen phosphate, disodium hydrogen phosphate, trisodium phosphate, thiab lwm yam thiab condensed phosphates.Refined phosphoric acid yog siv los ua calcium phosphate rau pub.Siv rau hlau nto phosphating kev kho mob, formulated electrolytic polishing tov thiab tshuaj polishing tov rau polishing txhuas khoom.
(7) Pharmaceutical kev lag luam rau kev tsim cov sodium glycerophosphate, hlau phosphate, thiab lwm yam, tab sis kuj rau kev tsim cov zinc phosphate raws li kev kho hniav Chemicalbook dental fillings nplaum.Siv los ua ib qho catalyst rau phenolic resin condensation, dyes thiab intermediates zus tau tej cov desiccant.Kev lag luam luam ntawv rau kev npaj ntawm so offset xim luam ntawv phaj stains ntawm cov tshuaj ntxuav.Nws kuj yog siv los tsim cov kua impregnating rau matchsticks.Metallurgical kev lag luam rau zus tau tej cov phosphoric acid refractory av nkos, txhim kho lub neej ntawm steelmaking rauv.Nws yog tus neeg sawv cev solidifying ntawm cov roj hmab muab tshuaj txhuam thiab cov khoom siv raw rau kev tsim cov ntaub ntawv inorganic.Siv nyob rau hauv kev lag luam xim raws li antirust xim rau hlau.
(8) Kev txiav txim siab ntawm chromium, npib tsib xee, vanadium muaj pes tsawg leeg hauv cov hlau, hlau tiv thaiv xeb, roj hmab coagulant, kev txiav txim siab ntawm cov tsis muaj protein ntau hauv cov ntshav, tag nrho cov roj cholesterol thiab tag nrho cov ntshav qabzib thiab lwm yam.Crystallized phosphoric acid feem ntau yog siv hauv microelectronics, roj teeb lub zog siab, laser iav thiab lwm yam txheej txheem tsim khoom, ua cov khoom siv hluav taws xob siab, cov khoom siv kho mob.
