Hauv kev tsim thiab tsim khoom ntawm Yoke Phaj, kev kho saum npoo tsis yog rau kev zoo nkauj xwb, tab sis qhov tseem ceeb tshaj plaws, nws ua haujlwm rau: cais tawm corrosive media, txhim kho kev hnav thiab cuam tshuam, ua kom ntev kev pab cuam lub neej, ua tau raws li kev tiv thaiv kev tiv thaiv dej hiav txwv, thiab ua raws li cov ntawv pov thawj thoob ntiaj teb. Cov txheej txheem kev kho deg sib txawv yog ua raws li qhov sib txawv siv ib puag ncig, kev siv nyiaj txiag, thiab cov qauv tsim.
Kub-dip galvanizing yog thawj txheej txheem kho saum npoo rau cov phaj yoke. Tom qab tshem tawm cov xeb, cov ncej ncej, ua los ntawm cov pa roj carbon steel lossis qis- alloy steel, yog tag nrho rau hauv molten zinc ntawm qhov kub thiab txias. Qhov no ua ib qho kev sib xyaw ua ke los tiv thaiv- txheej txheej corrosion ntawm cov hlau, uas muaj cov zinc txheej ntshiab thiab zinc- txheej hlau alloy. Tam sim no nws yog qhov siv dav tshaj plaws, tus nqi - zoo, thiab tsim nyog txoj kev kho saum npoo rau ntev - siv sab nraum zoov siv fais fab fittings thiab steel structural Cheebtsam. Lub zinc txheej thickness feem ntau yog 65μm ~ 120μm, nrog hnyav - lub luag haujlwm tiv thaiv - corrosion coatings ncav cuag 150μm+. Raws li ib txwm muaj, nws tuaj yeem tiv taus 500 ~ 1000 teev ntawm kev ntsuas ntsev tsuag, thiab hauv thaj chaw ntug dej hiav txwv, 300 ~ 500 teev. Qhov zoo ntawm kub-dip galvanizing muaj xws li muaj zog heev los tiv thaiv- kev ua haujlwm corrosion, ua kom xeb{23}}kev ua haujlwm pub dawb rau 20 ~ 30 xyoo nyob rau hauv ib puag ncig sab hauv. Nws kuj boasts zoo heev zinc adhesion, tsis kam mus cuam tshuam, puas, thiab cua thiab xuab zeb yaig, thiab sacrificial anode tiv thaiv. Txawm tias muaj kev khawb hauv zos, zinc tseem yuav tiv thaiv cov hlau substrate. Nws yog qhov tsim nyog rau kev thauj mus los hauv hiav txwv, tsis muaj kev cuam tshuam tag nrho los ntawm cov thawv ntim khoom thiab cov av noo ib puag ncig, thiab muaj cov nyiaj tsis sib xws - grey tsos, zoo ib yam li cov tsoos zoo li lub zog fittings. Nws yog tsim nyog rau high voltage thiab ultra- high voltage kis kab, onshore thiab offshore cua fais fab txuas yokes, photovoltaic brackets, nqa thiab hoisting txuas daim hlau, thiab ntev -lub sij hawm sab nraum zoov, high humidity, thiab nruab nrab corrosive ib puag ncig.
Electroplating zinc yog txheej txheem uas siv electrolysis tso ib txheej nyias ntawm zinc mus rau saum npoo ntawm ib tug yoke phaj, muab ob txoj kev tiv thaiv corrosion los ntawm cathodic tiv thaiv thiab lub cev barrier. Zinc txheej thickness ranges ntawm 5μm mus rau 15μm, thiab nws withstands ntsev tsuag tshuaj ntsuam xyuas rau 48 mus rau 96 teev. Cov khoom uas tau tshwm sim muaj lub ci, silvery -dawb tsos uas zoo nkauj txaus nyiam thiab huv si. Nws qhov zoo muaj xws li lub ntsej muag ci, zoo nkauj zoo nkauj, zoo nkauj zoo nkauj, siab qhov tseeb, tsis muaj qhov ua haujlwm deformation, tsis muaj qhov txhaws ntawm qhov, tsis xav tau tom qab- ua tiav, thiab tus nqi qis, ua rau nws tsim nyog rau qis - nqi, luv- cov khoom siv.
Cov hmoov txheej yog hais txog electrostatic adsorption ntawm cov hmoov yas rau saum npoo ntawm Yoke Plate, ua raws li siab -kub curing los ua ib txheej tawv. Cov txheej tuab yog 60-120μm, ua rau lub ntsej muag du, tiaj tus nrog cov khoom zoo nkauj zoo nkauj. Nws muaj qhov sib xws thiab ua kom zoo nkauj ua tiav, haum rau hauv nroog cov phiaj xwm hluav taws xob thiab kev tsim kho vaj tse. Nws yog resistant rau tshuaj corrosion thiab acids / alkalis, muaj zoo rwb thaiv tsev zog, thiab yuav siv tau rau tej yam hluav taws xob yam ntxwv Cheebtsam. Ntau yam xim muaj rau kev txheeb xyuas yooj yim. Nws yog qhov tsim nyog rau cov phiaj xwm kev tsim kho vaj tsev, cov chaw tsim hluav taws xob substation, cov khoom siv sab hauv tsev, photovoltaic taug qab brackets, thiab tsis yog - cov khoom thauj khoom tseem ceeb uas cov xim tseem ceeb.
Cov tshuaj tsuag kua muaj xws li siv cov tshuaj epoxy, alkyd, los yog xeb -cov xim tiv thaiv los ua cov yeeb yaj kiab tiv thaiv organic. Nws muaj kev ywj pheej ntawm kev xaiv xim, daim ntawv thov yooj yim, thiab tus nqi qis. Haum rau cov khoom siv ib ntus thiab siv sijhawm luv luv -, nws zoo tagnrho rau cov khoom siv sab hauv tsev uas tsis tas yuav muaj kev tiv thaiv corrosion.
Rau 304/316 stainless hlau yoke daim hlau, pickling thiab passivation tshem tawm cov hlau dawb, tsim kom muaj chromium oxide tiv thaiv zaj duab xis- txheej txheem hu ua passivation. Qhov no txhim kho cov hlau tsis muaj zog tiv thaiv cov tshuaj ntsev thiab xeb, ua rau lub ntsej muag huv si, ci ntsa iab yam tsis hloov qhov tseeb qhov tseeb. Nws yog qhov kev xaiv zoo tshaj plaws rau marine thiab ntug dej hiav txwv ib puag ncig, haum rau offshore cua zog, offshore platforms, chaw nres nkoj, thiab tshuaj lom neeg thaj chaw.
Cov txheej txheem kev kho deg sib txawv muaj qhov sib txawv ntawm kev tiv thaiv corrosion. Feem ntau, kub-dip galvanizing> stainless hlau passivation> hmoov txheej> electro-galvanizing, thiab lawv cov kev pab cuam lub neej kuj txawv. Txhawm rau pab cov neeg siv xaiv, ntawm no yog qee qhov piv txwv: Rau qhov chaw sab nraum zoov zoo tib yam, kub -dip galvanizing yog qhov kev xaiv vim nws tus nqi siab -kev ua tau zoo, kev siv thoob ntiaj teb, kev ua neej ntev, thiab cov nqi tu qis. Rau offshore cua fais fab, ntug hiav txwv fais fab, thiab ntsev tsuag ib puag ncig, passivation yog qhov kev xaiv zoo tshaj plaws, muab qhov muaj zog tiv thaiv corrosion, tsis tas yuav tsum muaj kev saib xyuas, thiab hloov mus rau qhov chaw huab cua marine.
Kev kho saum npoo ntawm cov phaj yoke tsis yog "txheej txheem tiv thaiv xeb," tab sis yog ib qho tseem ceeb ntawm cov txheej txheem uas txiav txim siab cov khoom lag luam, kev hloov pauv ib puag ncig, kev nyab xeeb ntawm qhov project, thiab lub koob npe nrov thoob ntiaj teb. Cov txheej txheem sib txawv sib txawv raws li cov xwm txheej siv sib txawv, kev siv nyiaj txiag, thiab cov qauv thoob ntiaj teb. Xaiv qhov kev kho saum npoo zoo tuaj yeem tsis tsuas yog ua tau raws li kev tiv thaiv corrosion, tab sis kuj tswj cov nqi, tiv thaiv xeb thaum thauj hauv hiav txwv, thiab txhim kho cov neeg siv khoom txaus siab rau txawv teb chaws.
