Hot-dip galvanizing ke eng?

Hot-dip galvanizing ke mokhoa o tloaelehileng oa ho koahela bokaholimo ba tšepe ka lesela la zinki, sepheo sa ona e leng hothibela oxidation ea tšepe le kutu.

Hot-dip galvanizing ke ho qoelisa tšepe ea tšepe ka har'a mokelikeli oa zinki o qhibilihisitsoeng ho etsa lera le sireletsang. Mokhoa o ikhethileng ke o latelang:

Phekolo ea Pele:
Ho fokotsa mafura: Tlosa litšila tse kang oli, lerōle, joalo-joalo holim'a tšepe holim'a tšepe, ka kakaretso u sebelisa tharollo ea alkaline bakeng sa ho hloekisa.
Pickling: Sebelisa dilute hydrochloric acid kapa sulfuric acid ho tlosa oxide scale le mafome holim'a tšepe ho netefatsa hore ho na le sebaka se hloekileng.
Ho hlatsoa metsi: Tlosa lintho tse nang le asiti tse setseng nakong ea ho khetha ho qoba ho ama lits'ebetso tse latelang.
Phekolo ea thuso ea ho pola: Kenya sesebedisoa sa mosebetsi ka thuso ea plating (e kang zinki chloride solution) ho etsa filimi e sireletsang e tšesaane ho thibela holim'a tšepe ho tloha ho oxidizing hape pele ho galvanizing le ho ntlafatsa ho khomarela zinki.

Ho kenya galvanizing e chesang:
Kenya mosebetsi o entsoeng esale pele ka har'a motsoako oa zinki o qhibilihisitsoeng hoo e ka bang 450 ° C ho sebelisa zinki ka matrix ea tšepe ho etsa lesela la alloy ea zinki le lesela le hloekileng la zinki.

Ho phodisa:
Ntša sesebediswa sa mosebetsi ho tswa ho mokelikeli wa zinki, mme o se phodise ka moya kapa metsi ho etsa hore lesela la zinki le tiye kapele mme le thehe lesela le tshireletso le tshwanang.

Kalafo:
Ka linako tse ling phekolo ea passivation e hlokahalang ho thibela mafome a masoeu holim'a lera la galvanized.
Qetella bokaholimo ba mosebetsi, joalo ka ho tlosa li-nodule tsa zinki tse feteletseng, li-burrs, jj.

Tlhahlobo ea boleng:
Sheba botenya, ho khomarela, ponahalo, joalo-joalo ea lera la galvanized ho netefatsa hore boleng ba galvanizing ea workpiece bo kopana le maemo.

Litšobotsi tsa ho futhumatsa hot-dip galvanizing: lesela la zinki le teteaneng ebile le na lekhanyetso e matla ea kutu, e loketseng bakeng satšebeliso ea nako e telele ea kantle, empa bokaholimo bo makukuno le ponahalo e mpefala hanyane.

Lihlahisoa tse tšoaroang ka li-galvanizing tse chesang li sebelisoa haholo ho lisebelisoa tse kang kaho, lipalangoang, motlakase, indasteri ea matla, mechine le lisebelisoa tse boima, ho hloekisa metsi le lisebelisoa tsa tikoloho, ho etsa likoloi, temo le ranch, joalo-joalo Ka mohlala, ka lithapo tsa lifti:liporo tsa lifti, masakana a terene, masakaneng a lithapo le masakamane,Tataiso ea seporo se kopanyang poleiti, meaho ea tšepe ea shaft, litšepe tsa balebeli le lisebelisoa tsa polokeho, masakaneng a lisebelisoa tsa motlakase le mabone, li-fasteners (liboutu, linate) e boetse e hloka galvanizing e chesang.
