Chromium Phosphate Hydrate Description
Chromium phosphate hydrate (chromium(III) phosphate hydrate) piav qhia txog cov tshuaj inorganic nrog cov tshuaj formula CrPO4•x(H2O), qhov twg x=0, 4, lossis 6. Txhua yam yog cov xim sib sib zog nqus. Anhydrous CrPO4 yog ntsuab. Lub hexahydrate CrPO4•6H2O yog violet.
Chromium phosphate hydrate yog violet crystal(s). Nws poob dej maj mam ntawm cua sov thiab ua tsis muaj dej tom qab 1h ntawm 800 degree lossis 3-4h ntawm 500 degree
Cov xim uas muaj chromium (III) phosphate tau siv los ua cov tshuaj tiv thaiv corrosion rau cov hlau. Cov xim muaj cov kua qaub aqueous acidic chromium (III) phosphate uas hloov mus rau cov yeeb yaj kiab zoo ib yam thaum siv rau cov hlau hnyav siv hauv kev tsim khoom thiab khoom siv xws li zinc, zinc alloy, aluminium thiab aluminium alloy substrates. Kev siv cov txheej txheem suav nrog electroplating, immersing lossis txau cov tshuaj rau ntawm qhov chaw ntawm lub substrate.
Chromium (III) phosphate muaj ntau yam kev siv hauv kev lag luam polymer. Kev sib xyaw chromium (III) aluminium phosphate yog dav siv los ua ib qho catalyst hauv alkylation ntawm aromatic hydrocarbons siv cawv xws li methylation ntawm toluene siv methanol. Cov cawv yog lub cev qhuav dej rau hauv ether thaum cov khoom siv hloov pauv alkyl tuaj yeem siv los ua ib qho nruab nrab hauv kev tsim cov khoom siv hluavtaws xws li poly (ethylene terephthalate).
Pretreatment nrog chromium (III) phosphate-silicate kuj yog siv los ua cov qauv laminated los ua kom muaj kev vibration thiab suab nrov hauv lub cev muaj zog.
