Dab tsi yog qhov tsis zoo ntawm kub - dip galvanizing?

Dab tsi yog qhov tsis zoo ntawm kub - dip galvanizing?
Cov tub ntxhais tseem ceeb ntawm kub - dip galvanizing nyob rau hauv cov kev txwv kub siab, cov nqi siab, thiab kev pom zoo thiab kev ua yeeb yam thiab kev ua yeeb yam thiab kev ua yeeb yam thiab kev ua yeeb yam thiab ua cov kev txiav txim siab thiab ua cov kev txiav txim siab thiab ua cov kev ua ub no. Cov lus tsis txaus no ncaj qha txiav txim siab tias nws tsis haum rau txhua qhov xwm txheej.
I. Cov neeg tsis zoo: Tsib qhov kev txwv loj los ntawm cov txheej txheem los thov
1. Tsis zoo ib qho kev sib xyaw vim muaj qhov kub
Qhov no yog qhov tseem ceeb tshaj plaws ntawm kub - dip galvanizing. Cov txheej txheem xav tau kev raus dej rau hauv Molten Zinc ntawm qhov kub tshaj 450 degree, uas ncaj qha rau ob hom tseem ceeb ntawm ntu:
Thaum tshav kub kub -} rhiab (qhov chaw rhiab (xws li nyias-} walled steel kav (thicknesses<2mm, prone to bending and deformation), precision gears (high temperatures change the metal's hardness, resulting in loss of tooth profile accuracy), and assemblies with bearings or insulation layers (high temperatures can burn the insulation and cause bearing seizure).
High-carbon/alloy parts: Some metal materials are incompatible. For example, high-carbon steel (carbon content >0.6%) Ua nkig ntawm cov hlau kub, thiab siv lub zog chromium (pawv siab)
Kub - dip galvanizing, thiab cov khoom siv khoom siv hluav taws xob ntau dua li txias rau nruab nrab- qhov me me.
Cov cuab yeej siv tau: Yuav tsum siv kev tsim kho ntawm qhov siab - kub siv roj, thiab cov ua kua rau thaum xub thawj lub zog 5}}
Tus nqi tsav tsheb: Rau txhua lub tooj si ntawm cov txheej txheem, hluav taws xob thiab zinc cov khoom siv ib leeg yog 30}}- dip galvanizing. Cov nqi ua ib chav nyob ib txwm muaj 2-3 lub sij hawm uas txias-dip galvanizing.
Tus nqi ntawm seem: kev kub siab tsim cov npoo ntawm cov ntu ntawm 5%, thiab cov nqi rov qab ua kom zoo nkauj ntxiv rau cov nqi qis dua li 5%, thiab cov khoom siv tsis zoo.
Qhov kub -} dip galvanized saum npoo muaj "dinc barangles" (nyiaj} grey} grey} grey grey xim.
Rau cov ntawv thov uas yuav tsum tau ua kom zoo nkauj (xws li cov khoom siv hlau sab nraum zoov lossis cov tshuaj tsuag ntxiv thiab cov xim yuav tsum muaj, tsis li ntawd yuav tshwm sim ntxhib thiab pheej yig.
Lub tiaj tiaj tiaj ntawm cov txheej tsis zoo, thiab cov zos zinc no los ntawm zinc kev) thiab tsis}} galnt next galosn tsis tau nthuav tawm) tuaj yeem tsim kho). Cov no yuav tsum tau polishing ua ke thiab kho, nce qib tus txheej txheem.
4. Kev ua tiav yog qhov nyuaj thiab yooj yim ua rau kev puas tsuaj.
Txawm hais tias kub kub - dip galvanizing muaj ntau dua cov tawv nqaij, nws tseem muaj tsawg dua los ntawm cov txheej txheem tuab, ua rau muaj kev ua kom muaj teeb meem.
Txiav / vuam txwv: Yog tias qhov yuav tsum tau txiav tom qab galvanizing, yuav tsum tau kho cov khoom siv tshiab, xws li re- thov zinc pleev xim). Lub siab kub thaum lub sij hawm vuam yuav hlawv cov txheej zinc ib ncig ntawm Weld, thiab zinc vapor tuaj yeem cuam tshuam weld zoo (piv txwv li, tsim cov hws). Cov duab nyuaj nyuaj yog qhov nyuaj rau lis: Rau qhov uas tsis pom kev zoo nkauj (xws li kaw cov kab noj qab haus huv), lossis cov kab mob siab heev (ua kom zoo tshaj plaws sab hauv lub qhov, sib sau zinc nodules. Qhov no tuaj yeem ua rau muaj kev tawm tsam lossis tawg ntawm qhov chaw vim kev nthuav dav ntawm huab cua los ntawm tshav kub. Qhov no yuav tsum tau ua ntej -}}} Venting lub qhov kom cia rau qhov cua, ntxiv ntawm cov txheej txheem.
5. Ib puag ncig thiab kev phom sij kev nyab xeeb yuav tsum tau tswj nruj
Txawm hais tias cov tuam txhab ua raws cai tuaj yeem tswj cov kev phem paug, ib puag ncig kev nyab xeeb thiab kev nyab xeeb ib puag ncig nyob:
Cov pa phem ua si: high - kub molten zinc Tshaj tawm zinc vapor (suav nrog zinc oxide). Yog tias cov fumes tsis yooj yim sau, lawv tuaj yeem ua rau lub pa ntawm cov neeg ua haujlwm ua haujlwm. Ntev -} Lub sij hawm kis tau tuaj yeem ua zinc ua npaws (cov tsos mob xws li kub taub hau thiab leeg nqaij).
Cov khib nyiab pov tseg: Qhov tsim Dinc Slag Slag thiab pov tseg zinc kua yog cov khoom txaus phom sij thiab yuav tsum tau daws los ntawm cov tsev muaj peev xwm. Kev pov tseg yam tsis muaj kev tso cai tuaj yeem paug av thiab ua kom kim.
Kev Nyab Xeeb Kev Nyab Xeeb: Txiaj Ntsig Ntawm Cov Siab- qhov kub thiab txias thiab txias Cov chaw no siab heev ntawm kev tswj hwm kev nyab xeeb.
Ii. Ntsiab lus: Cov xwm txheej twg yuav tsum zam dhau kub - dip galvaning?
Tom qab txheeb xyuas qhov tsis txaus ntseeg ntawm kub - dip galvanizing, ua ntej cov txheej txheem no hauv cov xwm txheej hauv qab no:
Qhov yuav tsum tau ua yog rau qhov chaw muaj ntshav, nyias {{0} {{{{}} pa taws (xws li cov hluav taws xob sib txawv thiab cov zog me me).
Cov peev nyiaj tau txwv, thiab ntev {-}} ntu sab nraum zoov tiv thaiv tsis tas yuav (xav kom lub neej <5 xyoo).
Lub ntsej muag kom zoo nkauj yog qhov xav tau heev, thiab cov xim ntxiv / hmoov txheej txheej yog qhov tsis xav tau.
Cov feem yuav tsum muaj cov txheej txheem txuas ntxiv xws li txiav thiab vuam.
