Kupyolera mu wakuda passivation madzi mankhwala (c2D) okhala mchere siliva kapena mchere wamkuwa, wakuda passivation filimu aumbike ndi makulidwe pafupifupi 10-15μm. Mtengo wake ndi wokwera koma mawonekedwe ake ndi apadera.

Gwiritsani akuda nthaka passivation (c2C), ❖ kuyanika makulidwe 8-15μm, mchere kutsitsi mayeso akhoza kufika maola oposa 72, zokongola maonekedwe, bwino odana ndi dzimbiri ntchito.

GB/T 882-2008 "Pin" muyezo, m'mimba mwake mwadzina 3-100mm, zipangizo monga zitsulo mpweya, zitsulo zosapanga dzimbiri, etc., electrogalvanized wosanjikiza makulidwe 5-12μm, mogwirizana ndi c1B kapena c1A pambuyo mankhwala zofunika.

Mtundu wa zinc passivation process (c2C) umatengedwa, makulidwe a zokutira ndi 8-15μm, ndipo kukana kwa dzimbiri kwa mayeso opopera mchere ndi maola opitilira 72, omwe ali ndi ntchito zotsutsana ndi dzimbiri komanso zokongoletsera.

Zimapangidwa ndi ma bolts osunthika, machubu okulitsa, zochapira zosalala, zochapira masika ndi mtedza wa hexagonal. zinthu zambiri mpweya zitsulo (monga Q235), ndi makulidwe a wosanjikiza electrogalvanized ndi 5-12μm, amene akukumana ISO 1461 kapena GB/T 13912-2002 mfundo.

Rainbow chromate passivation (c2C) amachitidwa pamaziko a electrogalvanizing kupanga mtundu passivation filimu ndi makulidwe pafupifupi 8-15μm. Mayeso opopera mchere amatha kupitilira maola 72 popanda dzimbiri loyera.

Wopangidwa ndi Q235 carbon steel ndi zipangizo zina, pamwamba ndi electro-galvanized, ndipo makulidwe ❖ kuyanika nthawi zambiri 5-12μm, amene amakwaniritsa zofunika pambuyo mankhwala c1B (buluu-woyera zinki) kapena c1A (wowala nthaka) mu GB/T 13911-92 muyezo.
