Dab tsi yog prepainted xim steel kauj?
Khoom txhais
Prepainted steel kauj yog cov khoom ua los ntawm kub dip galvanized steel, kub dip galvalume steel, electro galvanized steel, thiab lwm yam., uas yog coated nrog ib los yog ob peb txheej ntawm ntuj txheej rau saum npoo tom qab nto pretreatment ( tshuaj degreasing thiab tshuaj hloov dua siab tshiab kho ) , tom qab uas kho nrog kev pab ntawm ci. Nws yog lub npe hu uaxim coated steel kaujnrog ntau yam xim ntawm cov organic coatings, thiab raug xa mus rau ua ntej pleev xim rau steel kauj.
Khoom nta
Prepainted coils yog lub teeb yuag thiab zoo nkauj, muaj kev tiv thaiv corrosion zoo, thiab tuaj yeem ua tiav ncaj qha. Lawv muab cov khoom siv tshiab rau kev tsim kho kev lag luam, kev lag luam shipbuilding, tsheb tsim kev lag luam, kev lag luam hauv tsev, kev lag luam hluav taws xob, thiab lwm yam.
Kev Txhim Kho Keeb Kwm Ntawm Pre painted Coil Steel
Cov txheej txheem ntawm Prepainted Steel Chev
Muaj ntau ntau cov txheej txheem rau prepaintedxim coated steel coils. Cov txheej txheem feem ntau siv yog cov txheej txheem rau cov menyuam txheej + txheej txheem ci. Txij li feem ntau cov txheej txheem rau kev tsim kho yog ob zaug-coated, cov txheej txheem ob-txheej thiab ob-ci txheej txheem yog cov txheej txheem xim txheej ntau tshaj plaws. Cov txheej txheem tseem ceeb ntawm chav xim txheej muaj xws li pretreatment, txheej, thiab ci.
Qauv ntawm Prepainted Steel
1) Sab saum toj txheej: tiv thaiv tshav ntuj thiab tiv thaiv ultraviolet rays los ntawm kev puas tsuaj rau txheej; Thaum lub topcoat ncav cuag lub thickness, nws muaj peev xwm tsim ib tug tuab shielding txheej zaj duab xis, txo cov dej permeability thiab oxygen permeability.
primer txheej: pab ntxiv dag zog rau qhov adhesion rau substrate, ua rau nws tsis tshua muaj rau cov xim rau desorb tom qab cov xim zaj duab xis yog permeated nrog dej, thiab kuj txhim kho corrosion kuj, vim hais tias cov primer muaj corrosion-inhibiting pigments, xws li chromate pigments, uas passivate lub anode thiab txhim kho corrosion kuj
2) Chemical conversion txheej: txhim kho qhov adhesion ntawm phaj (galvanized, galvalume, zn-al-mg, thiab lwm yam) thiab txheej (xim)
3) Hlau txheej: feem ntau zinc txheej, aluzinc txheej thiab zinc aluminium magnesium txheej, uas muaj kev cuam tshuam loj tshaj plaws rau kev pab cuam lub neej ntawm cov khoom. Lub thicker lub hlau txheej, qhov ntau dua qhov corrosion kuj.
4) Base hlau: txias dov phaj yog siv, thiab cov khoom sib txawv txiav txim siab qhov ua tau zoo ntawm cov phaj xim, xws li lub zog
5) hauv qab txheej: tiv thaiv cov hlau phaj los ntawm corroding los ntawm sab hauv, feem ntau muaj ob txheej txheej (2/1M lossis 2/2 primer txheej + hauv qab txheej), yog tias siv los ua cov phaj sib xyaw, nws raug nquahu kom siv ib txheej txheej ( 2/1)
