Iindaba

I-galvanizing eshushu, ekwabizwa ngokuba yi-hot-dip galvanizing kunye ne-hot-dip galvanizing, yindlela esebenzayo yokukhusela intsimbi yentsimbi, esetyenziswa kakhulu kwizakhiwo zetsimbi kunye nezixhobo kumashishini ahlukeneyo.Yinkqubo yetekhnoloji yokufumana ukutyabeka ngokuntywiliselwa intsimbi, intsimbi engatyiwayo, intsimbi ephosweyo kunye nezinye isinyithi kwisinyithi esinyibilikisiweyo okanye ialloy.Yindlela yonyango yentsimbi esetyenziswa ngokubanzi kunye nokusebenza okungcono kunye nexabiso kwihlabathi namhlanje.Iimveliso ezenziwe ngamazinki ashushu zidlala indima engenakulinganiswa nengenakubuyiselwa ekunciphiseni umhlwa kunye nokwandisa ubomi, ukonga amandla kunye nemathiriyeli yentsimbi.Kwangaxeshanye, intsimbi edityanisiweyo nayo iyimveliso yexesha elifutshane enexabiso eliphezulu elongezelelweyo elixhaswayo kwaye libekwe phambili ngurhulumente.
Inkqubo yokuvelisa
Imveliso kunye nokusetyenzwa kwekhoyili yentsimbi enokohlulwa ibe ngamanyathelo amathathu amakhulu: okokuqala, yonke ikhoyili yentsimbi yomtya iya kucholwa ukuze kususwe umhlwa kunye nokuhlanjululwa ukwenza umphezulu wentsimbi ekhandisiweyo uqaqambe kwaye ucoceke;Emva kokukhethwa, kuya kucocwa kwi-ammonium chloride okanye i-zinc chloride isisombululo se-aqueous okanye i-ammonium chloride kunye ne-zinc chloride exutywe isisombululo esinamanzi, kwaye emva koko ithunyelwe kwibhafu yediphu eshushu yenkqubo yokukhupha;Emva kokuba inkqubo yokufaka igalvanizing igqityiwe, ingagcinwa kwaye ipakishwe.

Imbali yophuhliso ye-galvanizing eshushu
Ukutshiza okushushu kwaqalwa phakathi kwinkulungwane ye-18.Yaphuhliswa ukusuka kwinkqubo yokufakwa kwetoti eshushu kwaye ingene kwinkulungwane yesine.Ukuza kuthi ga ngoku, igalvanizing yediphu eshushu iseyeyona nkqubo isetyenziswayo nesebenzayo ekuthinteleni ukuthotywa kwentsimbi.
Ngowe-1742, uGqr. Marouin wenza ulingelo lobuvulindlela malunga nokufakwa kwentsimbi eshushu kwidiphu waza wayifunda kwiRoyal College yaseFransi.
Ngo-1837, i-Sorier yaseFransi yafaka isicelo selungelo elilodwa lomenzi we-patent ye-hot-dip galvanizing kwaye yabeka phambili ingcamango yokusebenzisa indlela ye-galvanic cell ukukhusela intsimbi, oko kukuthi, inkqubo yokufaka i-galvanizing kunye nokuthintela umhlwa kumphezulu wentsimbi.Kwangalo nyaka, uCrawford wase-United Kingdom wafaka isicelo selungelo elilodwa lomenzi wechiza le-zinc plating kusetyenziswa i-ammonium chloride njengesinyibilikisi.Le ndlela iye yalandelwa ukuza kuthi ga ngoku emva kophuculo oluninzi.
Ngo-1931, uSengimir, injineli ebalaseleyo kushishino lwangoku lwesinyithi, wakha umgca wemveliso wokuqala wehlabathi oqhubekayo wokuntywila wentsimbi yentsimbi ngendlela yokunciphisa i-hydrogen ePoland.Le ndlela yayinelungelo elilodwa lomenzi wechiza eUnited States kunye nomgca wemveliso we-industri-dip galvanizing ogama linguSengimir wakhiwa eUnited States kunye ne-Maubuge Iron kunye neSityalo seNsimbi eFransi ngo-1936-1937, ngokulandelelanayo, ukudala ixesha elitsha eliqhubekayo, eliphezulu- isantya kunye nomgangatho ophezulu eshushu-dip galvanizing for strip steel.
Ngeminyaka yee-1950 neye-1960, iUnited States, iJapan, iBritani, iJamani, iFransi, iKhanada kunye namanye amazwe ngokulandelelanayo avelisa iipleyiti zentsimbi ezilunyunyisiweyo.
Ekuqaleni kweminyaka yee-1970, iBethlehem Iron kunye neNkampani yeNsimbi yaqulunqa i-Al-Zn-Si impahla yokugquma enegama lokurhweba elithi Galvalume, elinokumelana nokugqwala kwamaxesha angama-2-6 okokoko kucocekileyo zinc.
Kwiminyaka yoo-1980, ingxubevange ye-zinc-nickel eshushu yanda ngokukhawuleza eYurophu, eMelika nase-Australia, kwaye inkqubo yayo yabizwa ngokuba yi-Technigalva Okwangoku, i-Zn-Ni-Si-Bi iye yaphuhliswa kwesi siseko, esinokuthi sithintele kakhulu ukusabela kweSandelin. ngexesha lokutyalwa okushushu kwentsimbi ene-silicon.
Ngeminyaka yee-1990, iJapan iNisin Steel Co., Ltd. yavelisa i-zinc-aluminium-magnesium-coating material enegama lokurhweba le-ZAM, ukuxhathisa kwe-corrosion kumaxesha angama-18 kune-coating ye-zinc yendabuko, ebizwa ngokuba sisizukulwana sesine somhlwa ophezulu. izinto zokugquma ezixhathisayo.

Iimpawu zemveliso
·Inokwazi ukumelana nomhlwa kunye nobomi benkonzo ende kuneshiti eliqengqelekayo elibandayo;
·Unamathela kakuhle kunye nokuwelda;
·Uluhlu lwemigangatho ekhoyo lukhoyo: iflake enkulu, iflake encinci, akukho flake;
·Unyango olwahlukeneyo lomphezulu lunokusetyenziswa ukwenza i-passivation, i-oyile, ukugqiba, ukukhuselwa kwendalo, njl.
Ukusetyenziswa kwemveliso
Iimveliso ezishushu zediphu zisetyenziswa kakhulu kwiindawo ezininzi.Iinzuzo zabo kukuba banobomi obude bokuchasana nokubola kwaye banokuqhelana noluhlu olubanzi lweendawo.Bebesoloko beyindlela yonyango echasene nomhlwa.Isetyenziswa ngokubanzi kwinqaba yamandla, inqaba yokunxibelelana, uloliwe, ukhuseleko lohola wendlela, isibane sesibane sesitalato, amacandelo olwandle, amacandelo esakhiwo sentsimbi, amaziko ancedisayo, imboni yokukhanya, njl.
