Mankhwala Odziwika Pamwamba Pamaboti - Mtengo wa magawo JMET FASTENER

Kupaka: kugwiritsa ntchito zokutira pamwamba pa bolt kuti apange filimu yofananira yomwe imapangitsa kuti zisawonongeke komanso mawonekedwe ake.. Ubwino wake ndikuti umawoneka bwino, koma choyipa chake ndi chakuti sichikhalitsa ndipo chimakanda mosavuta.
Kutentha-kuviika galvanizing: kumiza bawuti mu zinc wosungunuka kuti isachite dzimbiri. Ubwino wake ndikuti uli ndi mphamvu zotsutsana ndi dzimbiri ndipo sizovuta kugwa, koma kuipa kwake n’kwakuti pamwamba sikukongola mokwanira.
Electroplating: kumiza bolt mu electrolyte ndikuyika chitsulo pamwamba pa bawuti kudzera mu electrolysis kuti ipititse patsogolo kukana komanso mawonekedwe ake.. Ubwino wake ndikuti pamwamba ndi yosalala komanso yokongola, koma choyipa chake ndi chakuti sachedwa kukhala ndi hydrogen embrittlement.
Dacro: kumiza ma bolts mu njira ya zinc-aluminium, kuonetsetsa kuti bawuti ikukhudzana kwathunthu ndi yankho musanagwedeze yankho lowonjezera ndikuwumitsa. Bwerezani ndondomeko yomwe ili pamwambayi 2-4 nthawi kupanga wandiweyani filimu pamwamba pa bawuti, kukwaniritsa zotsatira za anticorrosion. Ubwino wa njirayi ndikuti pamwamba ndi yokongola komanso yosavuta kugwa, koma choyipa chake ndi chakuti sichikhalitsa ndipo chimakanda mosavuta. Tsopano pali mawonekedwe a hexavalent opanda chromium, zomwe ndi zokonda zachilengedwe.
