Yintoni iZinc Phosphate Coatings

I-zinc phosphate iyathandeka xa kukho imfuneko yokumelana nomhlwa okuphezulu kune-iron phosphate. Ingasetyenziswa njengesiseko semizobo (ingakumbi kwi-thermosetting yengubo), ngaphambi kokuba umzobo obandayo / obandayo wenze intsimbi kunye nokusetyenziswa kwangaphambili kweoli yokukhusela / ukuthambisa.
Oku kudla ngokuba yindlela ekhethwayo xa kufuneka ubomi obude phantsi kweemeko eziyingozi. Ukwaleka kukwalungile kakhulu nge-zinc phosphate kuba iikristale zenza indawo enemingxuma enokuthi ifunxe kwaye ibambe ngomatshini ifilimu yokugquma. Kwelinye icala iinkqubo ze-zinc phosphate zidla ngokufuna amanqanaba onyango angaphezulu, kunzima kakhulu ukulawula kwaye kubiza kakhulu ukuyifaka nokusebenza. Ifilimu ye-zinc idla ngokufakwa kwi-200-500 milligrams ngeenyawo zesikwere. Ixesha lilonke elifunekayo limalunga nemizuzu emi-4 kwisixokelelwano sokutshiza.
Kwipeyinti ye-zinc phosphate yokwaleka, ubunzima bokugquma buyohluka phakathi kwe-2 ukuya kwi-6 g/m². Akukho mfuneko yobunzima beengubo eziphezulu. Ubunzima bokugquma bomaleko we-zinc phosphate phambi kokuba umzobo obandayo / uguqulo olubandayo lwemisebenzi yentsimbi kufuneka lube phezulu ngokwentelekiso, luyohluka kuluhlu lwe-5 ukuya kwi-15 g/m². Ukugquma kwentsimbi / iinxalenye zentsimbi kufuneka ziphathwe nge-oyile okanye ngewax, ubunzima bokugquma bunowona mgangatho uphezulu phakathi kwe-15 - 35 g/m².
