Kub dip galvanized hlau yog ua los ntawm high-zoo qis- carbon steel hlau pas nrig, ua tiav los ntawm kev kos duab, pickling thiab xeb tshem tawm, siab -kub annealing, kub-dip galvanizing thiab txias.Kub-dip galvanizing yog dip melted hauv{6} zinc. Cov txheej txheem ntau lawm yog ceev thiab cov txheej yog tuab.Galvanized hlau hlau muaj ci tiav nrog txawm thiab txaus nyiam zinc txheej; tuab galvanized txheej thiab muaj zog corrosion kuj; zoo toughness thiab ruaj khov rau cov hlau, thiab tuaj yeem rov qab siv tau mus tas li yam tsis muaj kev hloov pauv zoo.Galvanized hlau hlau yog cov khoom hlau uas tau raug zinc{10}}coated thaum lub sij hawm tsim khoom. Cov hlau nws tus kheej muaj zoo heev toughness thiab elasticity, thiab cov zinc txheej muab corrosion kuj, ua rau nws haum rau siv nyob rau hauv hnyav ib puag ncig los yog av noo. Galvanized hlau hlau feem ntau yog siv rau hauv kev tsim kho, kev ua liaj ua teb, khoom siv tes ua, thiab xaws, nrog rau kev siv hluav taws xob engineering, ntim khoom, thiab kev siv hauv tsev txhua hnub. Nws muaj ntau yam kev siv yog yooj yim los ntawm ntau yam ntawm cov hlau diameters, xws li 0.4mm, 0.8mm, 1.2mm, 2.0mm, thiab 5mm. Customization kuj tseem ua tau, txaus siab rau cov neeg siv khoom xav tau.
Kub Dipped Galvanized Hlau yog tsuas yog siv nyob rau hauv kev tsim kho raws li binding hlau, nthuav qhia txoj kev fencing li fencing hlau, khi cov paj li hlau ties nyob rau hauv lub vaj thiab vaj, thiab barbed hlau los yog hlau mesh ua raws li weaving hlau, kev lag luam, kev ua liaj ua teb, tsiaj husbandry, handicrafts, khoom ntim thiab niaj hnub pej xeem siv.
Degrease qhov chaw ntawm cov hlau uas ua tau raws li cov lus qhia tshwj xeeb. Soak nws hauv sulfuric acid los yog hydrochloric acid kom tshem tawm oxides thiab xeb. Raus nws hauv zinc chloride los yog ammonium chloride tov los tiv thaiv oxidation thiab txhim khu zinc wettability. Tom qab ziab, nws yog npaj rau galvanizing. Tag nrho cov kev npaj no ua kom muaj kev ruaj ntseg zinc txheej.
Cov hlau kho tau muab tso rau hauv ib da dej zinc ntawm qhov kub ntawm 450 degree. Qhov no dissolves cov hlau -raws li nto, tsim ib zinc- hlau alloy txheej. Zinc ions tom qab ntawd diffuse los tsim cov txheej txheem miscible, uas ua rau cov zinc txheej ntshiab npog qhov chaw. Thoob plaws hauv cov txheej txheem galvanizing, ceev faj yuav tsum tau them rau qhov kub thiab txias ntawm da dej, lub sij hawm immersion, thiab rub- tawm ceev; txhua qhov kev nthuav dav cuam tshuam qhov zoo ntawm zinc txheej.Cooling pib, los ntawm huab cua los yog dej txias kom solidify zinc txheej. Tom qab ntawd chromatization yog ua los txhim kho corrosion kuj. Zinc txheej txheej saum npoo yog tshuaj xyuas, tsom rau qhov sib xws thiab qhov zoo ntawm qhov chaw.
Cov ntsiab lus dab tsi cuam tshuam rau qhov zoo ntawm Kub Dipped Galvanized Hlau?
Kev huv huv ntawm cov khoom siv raw: Roj, tso tawm cov khoom seem, lossis nplai ntawm qhov chaw tuaj yeem ncaj qha ua rau cov pinholes, blistering, lossis txawm tias flaking hauv txheej, txo qis corrosion kuj.
Kev kis kab mob ntawm lub plating da dej: Hlau ion paug los yog cov khoom sib xyaw ua ke tuaj yeem ua rau cov txheej txheej ntom ntom, ua rau pitting, roughness, thiab lwm yam teeb meem.
Parameter fluctuations: Galvanizing kub tsis tau raws li qhov yuav tsum tau muaj, pH qhov tseem ceeb sab nraum qhov kev pom zoo, lossis cov ntsiab lus sulfuric acid ntau dhau tuaj yeem ua rau cov txheej txheem nkig.
Zinc txheej thickness: Tsis txaus thickness ua rau cov txheej txheem tiv thaiv tsis muaj zog, thiab cov ntsiab lus phosphorus tsis txaus tuaj yeem txo cov ntsev tsuag tsis kam ntawm electroless npib tsib xee txheej.
Nws raug nquahu kom koj yuav Kub Dipped Galvanized Hlau los ntawm cov chaw tsim khoom rau kev ua haujlwm zoo.
Kub-dipped galvanized xaim xav tau kev tu thiab khaws cia kom ntev nws lub neej.
Cia: Khaws rau hauv qhov chaw qhuav, zoo- qhov cua nyob sab hauv tsev, tsis txhob ya raws thiab acidic/alkaline tej yam kev mob; tawm qhov sib txawv ntawm cov yob los tiv thaiv deformation los ntawm compression; xyuas kom zoo ntim kom tsis txhob khawb cov zinc txheej;
Siv: Tsis txhob khawb qhov chaw nrog cov cuab yeej ntse; tam sim ntawd siv zinc- nplua nuj xim rau welded pob qij txha kom tiv thaiv kev xeb hauv zos;
Kev tshuaj xyuas tsis tu ncua: Rau cov laj kab / nets, tshuaj xyuas cov zinc txheej txhua xyoo rau kev puas tsuaj lossis xeb; kho lossis hloov cov chaw cuam tshuam tam sim yog tias pom muaj teeb meem.
