Hloov kho Zinc Phosphate Description
Zinc phosphate yog ib qho inorganic compound nrog cov qauv Zn3 (PO4)2. Cov hmoov dawb no yog dav siv los ua cov tshuaj tiv thaiv corrosion ntawm cov hlau qhov chaw xws li ib feem ntawm cov txheej txheem electroplating los yog siv los ua cov xim primer. Nws tau tshem tawm cov ntaub ntawv tshuaj lom ntau raws li cov hmoov txhuas lossis chromium, thiab los ntawm 2006 nws tau dhau los ua cov tshuaj tiv thaiv corrosion feem ntau. Zinc phosphate coats zoo dua ntawm cov qauv crystalline dua li cov hlau liab qab, yog li tus neeg sawv cev ntawm cov noob feem ntau siv los ua kev kho mob ua ntej. Ib tus neeg sawv cev tshaj plaws yog sodium pyrophosphate.
Zinc phosphate muaj lub peev xwm ua kom muaj zog hauv cov hlau tsis muaj zog. Lub hauv paus ion ntawm no zinc phosphate reacts nrog hlau cation phaj los tsim ib tug muaj zog tiv thaiv zaj duab xis nrog hlau phosphate ua lub ntsiab lub cev. Qhov no tuab cov thawj zaj duab xis passus uas muaj insoluble hauv dej, featuring siab hardness, muaj zog adchesion. Nws tuaj yeem cuam tshuam nrog ntau cov hlau ions los tsim cov chromium tebchaw, thiab muaj cov nyhuv zoo los tiv thaiv xeb. Cov txheej ua los ntawm zinc phosphate muaj kev ua haujlwm zoo los tiv thaiv xeb uas ua haujlwm hloov cov hlau lead thiab chromium.
Zinc phosphate kuj yog ib qho dej me me thiab cov kua qaub-soluble zinc qhov chaw siv tau tshaj phosphates.
