Iyada oo loo marayo daaweynta dareeraha passivation madow (c2D) oo ka kooban milix qalin ah ama cusbo naxaas ah, filim passivation madow ayaa la sameeyay oo dhumucdiisu tahay 10-15μm. Kharashku waa sarreeyaa laakiin muuqaalku waa mid gaar ah.

Isticmaal midab leh zinc passivation (c2C), dhumucdiisuna waxay tahay 8-15μm, tijaabada buufinta milixdu waxay gaari kartaa in ka badan 72 saacadood, muuqaal midab leh, waxqabadka ka hortagga daxalka oo wanaagsan.

GB / T 882-2008 "Pin" heerka, dhexroor magaca 3-100mm, qalabka waxaa ka mid ah birta carbon, ahama, iwm, dhumucdiisuna lakabka electrogalvanized 5-12μm, waafaqsan c1B ama c1A shuruudaha daaweynta ka dib.

Habka passivation zinc midabka (c2C) waa la ansixiyay, dhumucdiisuna waxay daahan waa 8-15μm, iyo iska caabbinta daxalka ee tijaabada buufinta cusbo waa in ka badan 72 saacadood, kaas oo uu leeyahay labadaba ka hortagga daxalka iyo qurxinta.

Waxay ka kooban tahay boolal countersunk, tuubooyinka ballaarinta, weel fidsan, dhaqida guga iyo lawska laba geesoodka ah. Maaddadu waxay u badan tahay birta kaarboon (sida Q235), dhumucda lakabka elektiroonigga ah waa 5-12μm, kaas oo la kulma heerarka ISO 1461 ama GB/T 13912-2002.

Passivation chromate Rainbow (c2C) waxaa lagu sameeyaa iyadoo lagu salaynayo koronto-galvanization si loo sameeyo filim passivation midab leh oo dhumucdiisu tahay 8-15μm. Tijaabada buufinta milixdu waxay socon kartaa in ka badan 72 saacadood iyada oo aan lahayn miridh cad.

Made of Q235 steel carbon iyo walxo kale, dusha waa electro-galvanized, iyo dhumucdiisuna daahan sida caadiga ah waa 5-12μm, kaas oo la kulma shuruudaha daaweynta ka dib ee c1B (zinc buluug-cad) ama c1A (zinc dhalaalaya) ee GB/T 13911-92 heerka.
