2. Yintoni i-Dacromet Coating?

I-Dacromet (i-DACROMET®) i-non-electrolytic, i-coating inorganic-based inorganic coating eyenziwe nge-zinc kunye ne-aluminium flakes ehlakazwe kwi-binder ye-chromate. Ekuqaleni yaphuhliswa kwi-1970s ukulwa nokubola kwetyuwa yendlela kwizithuthi, isetyenziswe ngeendlela ze-dip-spin, i-spray, okanye i-dip-drain emva kwe-alkaline degreasing kunye nokucoca ngomatshini (akukho pickling ye-asidi isetyenzisiweyo). I-coating ke iphiliswa malunga ne-300 ° C, ivelisa i-thice (ngokuqhelekileyo i-5-15 μm), ifilimu efanayo ye-metallic silver-gray ebambelela ngokuqinileyo kwi-substrate yensimbi.

Isixhobo sayo sokukhusela sisebenza ngeendlela ezintathu ezongezelelweyo:

1. Ukukhuselwa komqobo -Izinc ezigqwethekileyo kunye neeflakes ze-aluminiyam zenza umqobo oxineneyo womzimba ngokuchasene nokufuma, ioksijini, kunye nezinto ezidliwayo.
2. Ukhuseleko lweCathodic (lwedini). - i-zinc corrodes ngokukhethekileyo, ukukhusela intsimbi engaphantsi nokuba i-coating yonakaliswe kancinci.
3. Ukunyamezela - iikhompawundi zechromium zenza iifilimu zeoksidi ezizinzileyo ezicothisa ukubola ngakumbi kwaye zincede ukutywina iziphene ezincinci kumphezulu.
