Ndi mankhwala otani a pamwamba pa kuika ulusi?

Kuchiza kwa ulusi kumatanthawuza njira yopangira chophimba pamwamba pa chogwirira ntchito kudzera munjira inayake.. Pambuyo pamwamba mankhwala, zoyika ulusi zimatha kupereka mawonekedwe okongola kwambiri, ndipo kukana kwa dzimbiri kwa ulusi woyika wokhawo kudzakhalanso bwino. Cholinga chofunikira kwambiri ndikupangitsa ulusiwo kuti udzilowetse wokha kuti usawonongeke, kuti muwonjezere kudalirika ndi kusinthika kwa chomangira. Electroplating, kutentha-kuviika galvanizing, ndi plating makina ndi njira zitatu zomwe zimagwiritsidwa ntchito kwambiri pochiza pamwamba pa ulusi.

1. Electroplating
Kuyika kwa electroplating kwa ulusi kumatanthawuza kumiza zigawo za ulusi zomwe zimafunika kuti zikutidwe mu njira inayake yamadzi.. Njira yamadzimadzi imakhala ndi zitsulo zosungidwa. Mwa njira iyi, pambuyo podutsa mumtsinje wamadzimadzi, zinthu zitsulo mu njira precipitate ndi kutsatira ulusi amaika. pa gawo lomizidwa la firmware. Ma electroplating a fasteners nthawi zambiri amaphatikizanso kupanga zinc, mkuwa, nickel, chromium, aloyi mkuwa-nickel, ndi zina. Nthawi zina otentha wakuda (buluu), phosphating, ndi zina. akuphatikizidwanso.

2. Hot dip galvanizing
Kuviika kotentha kwa zomangira ndiko kumiza zoyikapo ulusi wa zitsulo za kaboni mu bafa losungunuka la zinki lotenthetsera pafupifupi 510 ° C., kotero kuti aloyi yachitsulo-zinc pamwamba pa cholumikizira idzasinthidwa kukhala zinki. Kupeza pamwamba mankhwala zotsatira (zofanana ndi kutentha kwa aluminium plating)

3. Mechanical plating
Kuyika pamakina oyika ulusi kumatanthauza kugwiritsa ntchito njira zenizeni zakuthupi ndi zamankhwala kukhudza pamwamba pa ulusi woyikapo ndi ufa wachitsulo wokutira., kotero kuti zitsulo zokutira zimapanga zokutira pamwamba pa cholumikizira kudzera pakuwotcherera kozizira kuti mukwaniritse chithandizo cha Surface. Mawotchi plating a zomangira ndi oyenera makamaka zida zosinthira monga zomangira, mtedza ndi wacha.

Kuweruza khalidwe la ulusi Ikani pamwamba mankhwala, makamaka kuyang'ana ngati mphamvu ya anti-corrosion ya kuyika kwa ulusi ikuwonjezeka bwino komanso ngati kuwonjezeka kumakwaniritsa zofunikira.. Njira yowunikira ndikufanizira malo ogwirira ntchito a chinthucho, khazikitsani zoyeserera, ndi kuchita mayeso a dzimbiri pa izo. Gawo lachiwiri ndikuwunika mawonekedwe.
