Pamene workpiece ikufunika nthawi yayitali yosungira ndi yoyendetsa, imakhala yosavuta kutulutsa dzimbiri, ndipo mankhwala owononga nthawi zambiri amakhala dzimbiri loyera.Chogwiritsira ntchito chiyenera kuchepetsedwa, ndipo njira yodziwika bwino yodutsa ndi chromium-free passivation.
Ndiye ubwino wa zitsulo zosapanga dzimbiri zoteteza chilengedwe ndi chiyani (wopanda chromium) njira yothetsera dzimbiri pamafuta oletsa dzimbiri?Anti-dzimbiri mafuta ntchito filimu mafuta kutseka pores pa zitsulo pamwamba kudzipatula kukhudzana ndi mpweya ndi bwino kuteteza dzimbiri, Ndipotu, palibe anachita.Filimu yamafuta ndi yosavuta kuchotsedwa ndikuwonongeka ndikupita patsogolo kwa kupanga.
The chromium-free passivation ndi kugwiritsa ntchito oxidizing mu njira passivation kupanga REDOX anachita ndi chitsulo, ndipo zotsatira zake ndi kupanga woonda kwambiri, wandiweyani, ntchito bwino chophimba ntchito, ndipo mwamphamvu adsorbed pa zitsulo pamwamba pa filimu passivation. .
Njira imeneyi ndi mankhwala anachita.
Choncho pa nthawi yomweyo, tiyeninso kumvetsa ubwino wazitsulo zosapanga dzimbiri kuteteza chilengedwe(yopanda chromium) passivation solution?
1. Poyerekeza ndi njira yachikhalidwe yosindikizira thupi, chithandizo cha chromium chopanda chromium chimakhala ndi mawonekedwe osakulitsa makulidwe a chogwirira ntchito ndikusintha mtundu, kuwongolera kulondola komanso kuwonjezereka kwa chinthucho, kupangitsa kuti ntchitoyo ikhale yosavuta.
2. Chromium-free passivation imalimbikitsa mapangidwe a oxygen molecular structure passivation film pazitsulo zachitsulo, filimuyi ndi yowuma, yokhazikika, komanso mumlengalenga, motero, poyerekeza ndi njira yachikhalidwe yopaka mafuta odana ndi dzimbiri, passivation. filimu yopangidwa ndi chromium-free passivation imakhala yokhazikika komanso yosagwira dzimbiri.
Malingaliro a kampani EST Chemical Groupwakhala akumamatira "mtima kupereka makasitomala ndi mankhwala mpikisano ndi ntchito kuti phindu la anthu" ntchito chikhulupiriro, mosalekeza luso, makasitomala kuthetsa mavuto m'munda wa kupewa dzimbiri passivation, kupereka mankhwala apamwamba chatekinoloje, ndipo malinga ndi zofuna za makasitomala kuti apereke njira zonse zothetsera zosowa zapadera za makasitomala.Tadzipatulira kuti tipereke chithandizo chabwino ndi zinthu zabwino kwa kasitomala aliyense, ndipo tikuyembekeza kugwira ntchito nanu kuti tipambane!
