Iyini i-Zinc Phosphate Coatings

I-Zinc phosphate coating ikhethwa uma kunesidingo sokumelana nokugqwala okuphezulu kune-iron phosphate. Ingasetshenziswa njengesisekelo semidwebo (ikakhulukazi i-thermosetting i-powder coating), ngaphambi kokudweba okubandayo / ukwakheka okubandayo kwensimbi kanye nokusetshenziswa kwangaphambili kwamafutha okuvikela / okokugcoba.
Lena ngokuvamile indlela ekhethwayo lapho kudingeka ukuphila isikhathi eside ngaphansi kwezimo ezonakalisayo. Ukugqoka kuhle kakhulu nge-zinc phosphate ngoba amakristalu enza indawo enezimbotshana engakwazi ukucwilisa futhi ibambe ifilimu ngokuzenzakalelayo. Ngakolunye uhlangothi amasistimu e-zinc phosphate ngokuvamile adinga izigaba zokwelashwa ezengeziwe, kunzima kakhulu ukuzilawula futhi kubiza kakhulu ukuzifaka nokusebenza. Ifilimu ye-zinc ivame ukufakwa ku-200-500 milligrams ngonyawo lwesikwele. Isikhathi esiphelele esidingekayo cishe imizuzu emi-4 yesistimu yesifutho.
Ezimbotsheni ze-zinc phosphate zikapende wangaphansi, isisindo sokumboza siyahlukahluka phakathi kuka-2 - 6 g/m². Asikho isidingo sezisindo ezinengilazi eziphakeme. Isisindo sokumboza sesendlalelo se-zinc phosphate ngaphambi kokudweba okubandayo / ukusebenza kokuguqulwa okubandayo kwensimbi kufanele kube phezulu ngokuqhathaniswa, kuyahlukahluka kububanzi obungu-5 - 15 g/m². Ukuze kuhlanganiswe izingxenye zensimbi / zensimbi okufanele ziphathwe ngamafutha noma nge-wax, isisindo sokumboza sinezinga eliphezulu phakathi kuka-15 - 35 g/m².
