1.How kom rov txiav txim siab sai ntawm cov khawb?
Nta: Tsuas yog lub galvanized txheej yog puas, cov hlau txheej tsis raug, cov txheej txheem zinc yog qhov sib txawv ntawm cov metallic luster, thiab tsis muaj qhov muag tsis muaj tseeb thaum kov tau los ntawm tes;
Kev pheej hmoo: Yog tias tsis kho, Rust dawb yuav tshwm sim ua ntej, thiab xim liab yuav tshwm sim tom qab 3-6 lub hlis vim muaj kev qaug zinc txheej.
Nruab nrab
Cov yam ntxwv: lub galvanized txheej yog scratch kiag li, ua rau me me ntawm steel substrate. Tsaus Grey Substrate yog pom ntawm thaj chaw khawb, thiab tsis muaj qhov tseeb deformation ntawm ntug;
Kev pheej hmoo: Liab xeb me ntsis kuj yuav tshwm sim ntawm kev nthuav tawm hauv 24-48 teev, thiab nthuav dav sai raws li cov av noo nce ntxiv.
Txav Loj
Nta: nthuav tawm thaj chaw substrate> 1cm² lossis tob> 0.1mm, tej zaum yuav muaj nrog ntug kev deformation, lossis txawm tias muaj kev sib tsoo hauv zej zog);
Kev phom sij: pom tseeb xeb tshwm nyob rau hauv ib lub sijhawm luv luv (hauv 12 teev), thiab dej yuav ua tau nyob rau hauv cov khoob los tsim lub roj teeb "kaw roj teeb", nrawm hauv plab corrosion.
2.What yog li cas yog txoj kev kho mob xwm txheej ceev rau kev kos me?
Khoom npaj
Hom theem pib: Cov tshuaj tsuag txias txias zinc tsuag lossis zinc cov ntsiab lus ≥9%;
Cov hom: Zinc-raws li kev kho tus neeg sawv cev nrog passivation ua haujlwm.
3.Qhov nrog nrog cov khawb hauv qhov xwm txheej ceev?
Rust remover: neutral rust removal gel (containing corrosion inhibitors to avoid corrosion of the substrate, such as phosphoric acid-based rust remover); Primer: epoxy zinc powder primer (containing zinc powder>60%, nrog kev tiv thaiv cov Cathalic thiab tiv thaiv cov teebmeem) lossis inorganic zinc-primer (kub tiv taus, haum rau cov chaw ib puag ncig); Topcoat: Acrylic Braincoat (sab nraum zoov huab cua tiv taus) lossis epoxy topcoat (nyob sab hauv av noo noo (nyob sab hauv av noo noo) tau tshaj tawm.
4.Qhov nrog kev kos ntoo loj thaum muaj xwm ceev?
Mechanical ntxuav cov cuab yeej: Hlau txhuam, kaum-grinder;
Ntev-kav ntev epoxy zinc-tam sim no cov lus qhia (zinc cov ntsiab lus ≥70%, zaj duab xis tuab dua 50-80μμm;
Sau cov khoom siv: yog tias qhov ncauj kos yog ntau dua 0.1mm, epoxy putty yuav tsum tau siv los sau kev nyuaj siab;
Topcoat: Polyurethane Topcoat lossis chlorinated roj hmab topcoat.
5.Qhov kev ceev faj txog kev teb ceev xwm txheej?
Kev tswj hwm ib puag ncig
Kev ua haujlwm yuav tsum tau nqa tawm hauv ib puag ncig qhuav. Yog hais tias nws los nag lossis hws, nws yuav tsum tau them nrog cov ntaub yas thiab ua kom sov rau dehumidify, tsis li ntawd cov txheej yuav yooj yim npuas thiab poob;
Thaum qhov kub nyob hauv qab 5 degree, nws yog ib qho tsim nyog los siv cov xim qis-pleev xim, lossis cua sov lub substrate mus rau 10-30 degree.
Cov khoom siv tau sib xws
Muaj cov acid muaj zog tshem tawm yog txwv tsis pub muaj saum npoo ntawm galvanized txheej, txwv tsis pub nws yuav corinc txheej thiab ua kom muaj kev puas tsuaj;
The Primer thiab Topcoat yuav tsum phim.
Kev soj ntsuam tom ntej
Cov txheej txheej txheej txheej yuav tsum tau txheeb xyuas 1 lub lim tiam, 1 hlis, thiab 3 lub hlis tom qab kho. Yog tias patting lossis bubbling tshwm sim, qhov chaw tsis tau yuav tsum tau muab tshem tawm tam sim ntawd thiab rov muaj dua;
Kev kho mob kub ntxhov yog tsuas yog ntsuas ib ntus xwb. Kho kho tsis pub dhau lub sijhawm ntev li 6 lub hlis, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig corrosive heev.
