Cov khoom siv lub cev thiab tshuaj lom neeg Cov khoom siv ntshiab yog cov xim tsis muaj pob tshab uas tsis muaj kua lossis cov khoom siv lead ua orthorhombic, tsis muaj ntxhiab thiab qaub heev. Kev lag luam muaj 85 feem pua phosphoric acid yog cov xim tsis muaj xim, pob tshab lossis xim xim me ntsis, kua nplaum. Lub melting point yog 42.35 degree. Thaum lub boiling point yog 213 degree (poob H2O), pyrophosphoric acid yog generated. Cua sov rau 300 degree hloov mus rau metaphosphoric acid. Tus txheeb ze ntom ntom d181.834. Soluble hauv dej, soluble hauv ethanol. 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 thiab boric acid. Nws tuaj yeem ua rau cov tawv nqaij o thiab rhuav tshem cov ntaub so ntswg ntawm lub cev. Concentrated phosphoric acid yog corrosive thaum rhuab hauv porcelain. Hygroscopic.
Cov txheej txheem ntub dej phosphoric acid feem ntau yog siv los tsim 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 hydrogen phosphate rau pub. Nws yog siv rau phosphating kev kho mob ntawm hlau nto, npaj electrolytic polishing kua thiab tshuaj polishing kua rau polishing txhuas khoom. Nyob rau hauv kev lag luam kws tshuaj, nws yog siv nyob rau hauv lub tsim ntawm oily sodium phosphate, hlau phosphate, thiab lwm yam. Nws kuj yog siv nyob rau hauv lub tsim ntawm zinc phosphate raws li ib tug kho hniav filling nplaum. Nws yog siv los ua ib qho catalyst rau condensation ntawm phenolic resin, desiccant rau zus tau tej cov fuels thiab intermediates. Hauv kev lag luam luam ntawv, nws yog siv los npaj cov tshuaj ntxuav kom tshem tawm cov stains ntawm offset xim luam ntawv daim hlau. Kuj tseem siv rau hauv kev npaj ntawm matchstick stains. Hauv kev lag luam metallurgical, nws yog siv los tsim phosphoric acid refractory av nkos los txhim kho lub neej kev pab cuam ntawm steelmaking furnaces. Nws yog cov coagulant ntawm roj hmab slurry thiab raw khoom rau zus tau tej cov inorganic binder. Kev lag luam xim yog siv los ua cov xim hlau antirust.
Phosphoric acid yog ntim rau hauv polyethylene yas chim, thiab lub qhov ncauj ntawm lub thoob yuav tsum tau nruj nreem kaw nrog sab hauv thiab sab nrauv npog. Qhov hnyav ntawm txhua lub thoob yog 25, 30, 35kg, 330kg. Thaum cov neeg siv muaj cov kev xav tau tshwj xeeb, muab kev sib tham thiab kev thov. Yuav tsum muaj cov cim qhia pom tseeb ntawm lub pob, qhia tias: cov khoom npe, qhov tshwj xeeb, qhov hnyav, thiab kos npe ntawm "cov khoom corrosive". Nws yuav tsum tau muab cia rau hauv ib qho chaw txias, ventilated warehouse. Rau high-concentration phosphoric acid nyob rau hauv cheeb tsam txias nyob rau hauv lub caij ntuj no, yuav tsum tau them nyiaj mloog mus rau lub tshav kub preservation, tiv thaiv kom tsis txhob khov, thiab tiv thaiv lub thawv los ntawm tawg, prospering thiab to. Nws tsis tuaj yeem khaws cia thiab thauj ua ke nrog alkalis, tshuaj lom thiab lwm yam corrosive. Tiv thaiv los ntawm nag thiab tshav kub thaum caij tsheb thauj mus los. Thaum thauj khoom thiab tshem tawm, thov ua tib zoo saib xyuas, thiab kev cuam tshuam hnyav yog nruj me ntsis txwv tsis pub lub thawv ntim khoom tawg.
