Xov xwm

1. Muaj feem xyuam
Cov kev siv tseem ceeb ntawmkub-dip galvanizeddaim ntawv yog nyob rau hauv kev lag luam xws li tsheb, khoom siv hauv tsev, kev tsim kho engineering, khoom siv tshuab, khoom siv hluav taws xob, thiab kev lag luam teeb.
2. Lub ntsiab yog vim li cas rau cov zinc txheej ntog
Lub hauv paus tseem ceeb ua rau cov txheej zinc poob tawm suav nrog cov khoom siv raw thiab kev tsim khoom, nrog rau kev tsim khoom tsis sib haum thiab kev ua tiav.Vim oxidation nto, silicon tebchaw, siab oxidation cua thiab tiv thaiv roj dew point nyob rau hauv lub NOF seem ntawm raw cov ntaub ntawv, tsis tsim nyog huab cua roj piv, tsawg hydrogen txaus tus nqi, oxygen infiltration mus rau hauv lub cub tawg, tsis tshua muaj kub ntawm lub sawb hlau nkag mus rau hauv lub lauj kaub. , tsis tshua muaj kub ntawm NOF seem rauv, tsis tiav cov roj evaporation, tsis tshua muaj txhuas cov ntsiab lus nyob rau hauv lub zinc lauj kaub, ceev chav tsev ceev, tsis txaus txo, luv luv nyob rau hauv lub zinc kua, thiab tuab txheej.Kev ua haujlwm tsis sib xws suav nrog cov vojvoog khoov tsis sib haum, pwm hnav, khawb, pwm tshem tawm loj dhau lossis me dhau, tsis muaj cov roj stamping lubricating, thiab lub sijhawm ua haujlwm ntev ntawm cov pwm uas tsis tau kho lossis khaws cia.
3. Cov yam tseem ceeb uas ua rau xeb dawb yog
(1) Passivation tsis zoo, tsis txaus lossis tsis sib xws passivation zaj duab xis thickness;
(2) Qhov saum npoo tsis yog oiled;
(3) Residual noo noo nyob rau saum npoo ntawm txias dov sawb hlau;
(4) Passivation tsis huv kom qhuav;
(5) Thaum lub sij hawm thauj los yog cia, noo noo rov qab los yog nag lossis daus dampens:
(6) Lub sij hawm cia ntawm cov khoom tiav ntev dhau lawm;
(7)Kub dip galvanized ntawvyog nyob rau hauv kev sib cuag los yog khaws cia ua ke nrog lwm yam corrosive tshuaj xws li muaj zog acids thiab alkalis.
Cov xeb dawb tuaj yeem hloov mus rau hauv cov pob dub, tab sis cov pob dub yuav tsis tsuas yog tshwm sim los ntawm cov xeb dawb, xws li kev sib txhuam dub.
4. Lub sijhawm cia siab tshaj plaws
Yog tias kev siv roj, ntim khoom, kev xa khoom, thiab kev thauj mus los tau ua tiav raws sijhawm, qee cov khoom tuaj yeem khaws cia rau ntau tshaj ib xyoos, tab sis nws yog qhov zoo tshaj plaws los siv nws hauv peb lub hlis.Yog tias tsis muaj roj, lub sijhawm luv dua los tiv thaiv huab cua oxidation los ntawm kev cia ntev dhau.Lub sijhawm cia khoom tiag tiag yuav tsum yog raws li cov khoom lag luam uas phim cov khoom tiag.
5. Cov Ntsiab Cai ntawm Zinc Layer Maintenance
Nyob rau hauv tej yam ntuj tso corrosive, zinc preitizes diffuse corrosion tshaj hlau, yog li tuav lub hauv paus steel.Nyob rau hauv cov nqe lus ntawm corrosion kuj, zinc txheej yuav tsim ib tug tej yam kev tiv thaiv zaj duab xis los ntawm qhuav kom tsis txhob muaj huab cua oxidation sai, qeeb tus nqi corrosion, thiab tuaj yeem txhuam nrog zinc hmoov xim thaum tu kom tsis txhob xeb hlau thiab ua kom lub cev muaj zog thiab kev nyab xeeb yam ntxwv ntawm cov ntaub ntawv.
6. Lub hauv paus ntsiab lus ntawm Passivation
Cov tshuaj Chromium trioxide passivation rau kub dip galvanized ntawv tuaj yeem tsim tau lub tswb zoo li zaj duab xis.Lub trivalent chromium nyob rau hauv lub saturated kua passivation tsev neeg yog ib qho nyuaj rau yaj nyob rau hauv dej qhuav, nws lub cev tsis kaj siab, thiab nws muaj ib tug framing nyhuv.Lub hexavalent chromium nyob rau hauv passivation tsev neeg dissolves nyob rau hauv ib tug muaj zog electrolyte, uas muaj peev xwm muaj ib tug tswb zoo li cov nyhuv thaum lub passivation zaj duab xis yog khawb, thiab muaj cov nyhuv kho ntawm lub tswb zoo li zaj duab xis.Yog li ntawd, rau ib qho twg, cov zaj duab xis passivation tuaj yeem tiv thaiv cov pa los yog cov pa cua txias los ntawm tam sim ntawd corroding cov ntawv kub-dip galvanized, ua si lub luag haujlwm tu.
7. Txoj kev ua haujlwm ntawm corrosion kuj
Muaj peb txoj hauv kev los ntsuas qhov kev tiv thaiv corrosion ntawmkub-dip galvanized ntawv:
(1) Tshuaj tsuag ntsev;(2) Kev sim ntub dej txias;(3) Kev sim Corrosion.
