русский Koj cov kav dej txuas rau kev tawm tsam txuas mus xeb. Thiab ib zaug kev xeb pib, nws tuaj yeem sib kis tau sai thiab ua rau koj cov kav xa dej tag nrho tsis muaj zog.
Qhov ntawd yog qhov chaw galvanizing hlau nkag los. Los ntawm galvanizing cov khoom siv hlau pib, xws li carbon hlau, koj tuaj yeem tiv thaiv cov hlau los ntawm kev xeb thiab ua rau koj lub raj xa dej tau ntev.
Xav tsis thoob yuav ua li cas galvanize hlau los tiv thaiv cov kav dej? Nyeem rau kev ua kom tob ntxiv saib ntawm galvanizing thiab tsib txoj kev los galvanize hlau.
Nws Txhais Li Cas Rau Galvanize Hlau?
Cias muab, galvanizing yog txheej txheem ntawm ntxiv zinc rau hlau kom tiv thaiv nws. Los ntawm kev ntxiv ib txheej ntawm zinc, koj tuaj yeem tig ntuj tsim kev txhim kho rau hauv qhov chaw-tiv taus corrosion.
Vim li cas Thiaj Ua Piping Pros Galvanize Hlau?
Hlau yog lossi up againstkev hem thawj ntawm xebCov. Thaum xeb cov khoom siv, xws li ntsev, grime, noo noo, lossis tshuaj lom neeg, ua ke nrog cov hlau hauv cov hlau, nws tuaj yeem ua rau oxidation. Qhov tshwm sim yog hlau-oxide, lossis xeb. Cov xeb tsoo ua rau cov hlau thiab ua rau cov kav dej tawg thiab tawg.
Thaum lub sijhawm cov txheej txheem galvanizing, koj tiv thaiv hlau los ntawm ntxiv ib txheej ntawm zinc. Qhov kev tiv thaiv zinc no tiv thaiv hlau ntawm ob txoj kev:
1.Nws muab cov txheej nruab nrab ntawm cov hlau tsis zoo thiab cov ntsiab lus corrosive.
2.Nws tiv thaiv tiv thaivgalvanic corrosionCov. Zinc muaj kujcov cuab yeej anodicpiv rau ntau cov hlau. Raws li qhov anode, nws nrawm nrawm rau tso cov khoom hluav taws xob thaum muaj kev sib cuag nrog ntau duanoble hlauCov. Qhov kev txi no yog qhov yooj yim thaum lub hlau zoo ntawd yuav nyiag nyiag cov xaim hluav taws xob los ntawm cov hlau lossis lwm cov hlau.
Cov txiaj ntsig ntawm Galvanizing
Yog li cas galvanizing ua kom koj qhov system piping? Nov yog qee cov txiaj ntsig ntawm kev txhawb nqa yeeb nkab galvanizing.
Nws yog tus nqi-nqi.
Tej zaum koj yuav xav paub, "Yog tias galvanizing ntxiv cov khoom coj los tiv thaiv, vim li cas ho tsis cia li siv cov khoom lag luam stainless?" Cov lus teb yog: nqi.Stainless hlaupuas suav nrog ua kev txhim kho corrosion, tab sis nws zoo li yuav kim dua li cov hlau. Yog li, galvanizing muab txoj kev tsis raug nqi ntau dua ntxiv txheej txheej tiv thaiv rau lwm cov ntaub ntawv ruaj khov.
Nws ua tau zoo dua kev xaiv ua tau yooj yim.
Kev hloov pauv, xws li cov xim pleev xim lossis lwm cov txheej txheej hauv qab, tuaj yeem zoo li yuav daws tau yooj yim. Tab sis lawv tuaj nrog qee qhov tsis zoo. Ua ntej, lawv feem ntau nti los yog khawb, ua kom pom cov hlau hauv qab ua rau xeb. Thib ob, vim tias lawv hnav tau yooj yim, lawv yuav tsum tau rov ua ntawv thov dua tshiab. Thaum kawg, lawv nyiam tawg lossis tev thaum lawv raug kub lossis hloov mus rau sab nraum zoov.
Nws yog qhov tsawg zog ua haujlwm.
Galvanized hlau mus los ntawm cov txheej txheem khaus thaum lub sijhawm tsim khoom, tab sis ib zaug nws tau thov rau hlau, cov khoom lag luam npaj mus. Qhov ntawd txhais tau tias koj pab pawg tsis' Koj kuj tsis tas yuav nkim sij hawm npaj chaw, tshuaj xyuas kev txhawb rau khawb, lossis pleev qhov muag.
Hom kev qhia Galvanizing
Xav paub dab tsi galvanizing txoj kev tawm muaj? Ntawm no yog cov lus qhia luv luv ntawm yuav ua li cas galvanize hlau los tiv thaiv cov kav dej.
1. Kub-Dip Galvanizing
Kub-dip galvanizing yog ib qho ntawm cov txhim khu kev qha galvanizing cov kev xaiv muaj. Qhov tseeb, raws lubKoom haum American Galvanizers, kub-dip galvanizing kev teeb tsa hlau yuav ntxiv ntau dua 70 xyoo rau nws qhov kev thiav.
Thaum lub sijhawm cov txheej txheem galvanizing no, koj tso koj cov hlau rau hauv cov kua zinc. Vim tias koj tuaj yeem tso dej rau tag nrho cov khoom ib zaug, nws yog qhov kev xaiv zoo rau kev txhawb nqa yeeb nkab ntawm txhua daim duab.
2. Pre-Galvanizing
Pre-galvanizing yog ib txwm muaj nrog cov khoom lag luam uas zoo li niaj zaus hloov, xws li hlau los yog daim hlau. Txhawm rau ua ntej galvanize hlau, koj khiav nws los ntawm zinc ntxuav. Txawm li cas los xij, raws li lub npe pom zoo, ua ntej-galvanizing yog feem ntau ua tiav ua ntej kev tsim tsa. Qhov ntawd txhais tau hais tias cov kis uas tau txiav thaum tsim khoom yuav raug rau xeb.
3. Electrogalvanizing
Hloov chaw ntawm dipping lub hauv paus hlau hauv zinc da dej, electrogalvanizing, lossis electroplating, siv hluav taws xob tam sim no hloov zinc rau hauv hlau. Thaum koj lub hauv paus hlau txuas ua ke nrog cov tshuaj electrolyte thiab zinc, ib qho hluav taws xob tam sim no raug xa los ntawm cov ntsiab lus. Zinc ions ib txwm txav mus rau hauv cov hlau, ntxiv txheej tiv thaiv.
Electroplating ua kom yooj yim rau ntxiv ib txheej txawm los txhawb, tab sis cov txheej ntuag ua rau nyias nyias tshaj li cov txheej txheem kub.
4. Kev lag luam hlau
Nrog rau hlau txau lossis tshuaj txau thermal, koj tsuag zinc rau lub hauv paus hlau saum npoo. Qhov no yog txoj hauv kev ruaj khov rau txheej zinc cov kev tiv thaiv, tab sis nws nyhav coj tus nqi zoo ntawm kev npaj saum npoo av thiab cov neeg ua haujlwm tshwj xeeb. Qhov ntawd txhais tau tias feem ntau nws kim dua lwm txoj hauv kev ua haujlwm.
5. Kev Txheeb Ze
Thaum lub sijhawm ua haujlwm sherardizing, koj ntxiv cov hlau rhaub rau cov thawv uas muaj kev sib hloov, nrog rau cov xaim zinc. Txoj kev sib tsoo yob yog rhuab kom sov mus rau qhov kub thiab txias, qhov kawg zinc nws yaj dua, thiab cov zinc sib txuas nrog lub hauv paus hlau. Cov txheej txheem no yog nrov nrog cov ncauj lus kom ntxaws, xws li txhawb nqa uas muaj cov xov zoo.
