Painting thiab kev kho dua tshiab ntawm cov qauv hlau cov teeb tsa yog txoj haujlwm sib txuas nrog ntau qhov sib txuas xws li xeb, tiv thaiv xeb, thiab txheej.
1. Kev ntsuam xyuas ua ntej thiab npaj
Tshuaj Ntsuam Xyuas
Tshawb xyuas seb tus qauv steel muaj deformation, tawg, thiab xeb℃(me xeb: speid ntab xeb; muaj xeb: xeb
Sau cov teeb meem ntawm Welds thiab bolts uas yuav tsum tau kho, thiab muab cov kev ua tau zoo rau cov qauv txheej txheem.
Kev Ntsuam Xyuas Pejaleem
Paub meej tias lub hom phiaj ntawm lub Hoobkas (xws li cov tshuaj lom neeg thiab zaub mov noj uas muaj cov kev xav tau tshwj xeeb rau cov txheej txheej).
Txheeb xyuas corrosion yam: noo noo, kua qaub thiab alkali roj, kub thiab lwm yam, thiab xaiv cov sib thooj.
Xim Xaiv
Primer: Epoxy Zinc - Cov Khoom Siv Hluav Taws Xob (muaj zog dolosion (muaj zog ove {
Nruab nrab pleev xim: Epoxy huab hlau intermediate pleev xim (thickness thiab adhesion).
Topcoat: Polyurethane Topcoat (huab cua zoo tshaj plaws), cov tshuaj lom neeg ua kom zoo (fluorocarbon xim (huab cua ntev ntev ntxiv, haum rau ib puag ncig ntev).
Cov kev tshwj xeeb: Hluav Taws Kub {{- Retrutrant Txheej (xws li nthuav tawm hluav taws kub} Retardant Txheej).
2. Cov kauj ruam tsim khoom
Kev Kho Mob Nto (Cov Kauj Ruam Tseem Ceeb)
Tes Cuab yeej xeb Reb tshem tawm (ST2 qib): Hlau txhuam thiab duav los kho cov kab xeb xoob, haum rau thaj chaw me.
Txhua yam xeb tshem tawm (ST3 qib): Sandblasting (Sandblasting (sa2.5 qib yog qhov pom zoo kom kho
cov khoom nyuaj.
Ntxuav cov nplaim dej: Siv cov kuab tshuaj (xws li acetone) kom tshem tawm cov roj thiab hmoov av.
Kho tej yam tsis xws luag
Sau Weld Pores thiab Pits: Siv Epoxy Putty lossis Hlau Muab Tub Lim.
Hloov cov phiaj loj xeb hlau (corrosion ntau dua 30% ntawm daim qub tuab thiab yuav tsum tau hloov).
Primer txheej
Sib tov Epoxy zinc - Cov primated nplua nuj (nruj me ntsis tsim hauv kev faib ua feem) thiab paub tab rau 10-15 feeb.
Txau lossis txhuam hniav, zaj duab xis qhuav ntau dua los yog sib luag rau 60μm kom ntseeg tau tag nrho cov kev pab them tag nrho.
Recoating cov sijhawm sib nrug (saib cov lus qhia khoom lag luam, feem ntau yog 4-8 teev).
Nruab nrab xim thiab kos duab topcoat
Thov cov xim 1-2 ntu nruab nrab kom nce cov tuab ntawm txheej txheej txheej (tag nrho cov yeeb yaj kiab qhuav kom ua rau 120-200μm).
Tshawb xyuas seb tus thawj pib kho tau ua ntej lub sab topcoat yog tsim kom tsis txhob tom qhov hauv qab.
Nws raug nquahu kom tshuaj tsuag cov topcoat kom ntseeg tau tias cov xim tsis sib xws thiab zam kev sagging.
3. Tej yam yuav tsum tau sau tseg
Kev tsim kho
Lub ambient kub yog 5-35 degree, thiab cov av noo yog tsawg dua lossis sib npaug nrog 85%, yog li kom tsis txhob los nag, daus thiab cua hlob.
Qhov ntsuas kub saum npoo ntawm cov hlau yuav tsum yog saum 3℃saum cov lwg taw qhia kom tiv thaiv hws.
Kev Nyab Xeeb Kev Nyab Xeeb
High - Cov kev ua haujlwm siab xav tau scaffolding lossis siab {1} {1} Cov tsheb khiav haujlwm ntawm lub tsheb.
Hnav khaub ncaws tiv thaiv thiab tsom iav thaum lub sijhawm khau khiab kom tsis txhob muaj kev pheej hmoo ntawm cov nqaij ntuag.
Qhib hluav taws yog nruj me ntsis txwv nyob rau hauv hluav taws kub - Cov ntaub ntawv pov thawj cov chaw pov thawj, thiab cov xim tsev nyob deb ntawm qhov chaw taws.
Kev Tswj Xyuas Zoo
Siv cov ntsuas cua tuab los tshawb xyuas cov txheej txheej txheej tuab thiab chaw xyuas cov kev pab them nqi.
Txais Cov Qauv: ISO 12944 lossis GB / T 8923 (tsis muaj xau, npuas, pinholes).
4. Cov lus nug nquag nug
Rust - Kev tshem tawm cov teeb meem rov qab: tsis tiav ntawm cov xeb tuaj yeem tshwm sim los ntawm re ...} sanding kom txog thaum cov xim av.
Txheej Txhuam: Kev ua kom huv tsis txaus lossis tus thawj pib tsis kho tau, thiab ua haujlwm hauv zos.
Pw tsaug zog: Txau nrug deb yog qhov ze dhau los yog diluent yog ntau dhau, kho tom qab sanding.
5. Cov tswv yim txij nkawm
Txheeb xyuas txheej txheej txheej txhua xyoo thiab cov xim kho cov xim (xws li cov npoo thiab cov khoom siv tshuaj ntsuab kom xeb ua ntej).
Nquag ntxuav cov hmoov av hauv tsev,
