3. Daim ntawv thov
Phosphoric Acid China siv rau dab tsi?
Phosphoric acid feem ntau yog siv los ua chiv, uas suav txog li 90 feem pua ntawm kev tsim khoom.
khoom noj khoom haus
Khoom noj khoom haus qib phosphoric acid yog siv los acidify cov zaub mov thiab dej haus thiab muab lawv ib tug muaj zog los yog qaub saj.Ntau yam phosphates, xws li monocalcium phosphate, yog siv los ua cov khoom ntim.Phosphoric acid hauv cov dej qab zib tuaj yeem ua rau cov hniav corrosion.Phosphoric acid kuj tuaj yeem ua rau lub raum pob zeb, tshwj xeeb tshaj yog nyob rau hauv cov neeg uas yav tas los raug kev txom nyem los ntawm lub raum pob zeb.
Kev tshem tawm xeb
Phosphoric acid tuaj yeem siv los tshem tawm xeb los ntawm kev thov ncaj qha rau cov hlau xeb, cov cuab yeej hlau, lossis lwm qhov chaw.Phosphoric acid hloov xim liab-xim av hlau (III) oxide thiab Fe2O3 (xeb) rau hauv hlau phosphate thiab FePO4.
Cov kua phosphoric acid tuaj yeem siv rau impregnation, tab sis phosphoric acid siv rau kev tshem tawm xeb yog feem ntau npaj rau hauv daim ntawv ntawm gel.Ntau yam phosphoric acid gel formulations yog muag raws li xeb tshem tawm.Rov qab siv cov phosphoric acid yuav tsum tau hloov tag nrho cov xeb.Cov xeb kuj tuaj yeem raug tshem tawm nrog phosphate hloov txheej txheej.Cov txheej txheem no tuaj yeem tawm ntawm cov phosphate dub txheej uas muab kev tiv thaiv corrosion tsis zoo.
Kev kho hniav department
Phosphoric acid yog siv los ua cov tshuaj etching hauv kev kho hniav thiab orthodontics los ntxuav thiab roughen cov hniav ntawm cov hniav uas muab cov khoom siv kho hniav los yog muab tso rau.Phosphoric acid kuj muaj nyob rau hauv khw muag khoom noj tshuaj tiv thaiv xeev siab, uas kuj muaj cov piam thaj ntau.Cov kua qaub no kuj siv tau rau hauv ntau cov khoom siv hniav ntxuav hniav dawb kom tshem tawm cov quav hniav uas muaj nyob ntawm cov hniav ua ntej siv.
