Kev piav qhia
PE txheej yog luv rau Polyester txheej, uas muaj cov nplaum zoo rau cov khoom siv, thiab ua rau cov xim coated steel ntawv tau yooj yim ua thiab tsim. Vim tias tus nqi pheej yig thiab ntau yam xim thiab ci, hom txheej no yog siv dav hauv ntau cov khoom.
Cov txheej yuav yog kub tais galvanized hlau, kub duav galvalume hlau.
Lub neej luv:
Nyob rau hauv ib puag ncig ib puag ncig, lub sijhawm tiv thaiv xeb tuaj yeem ntev li 7-8 xyoo, tab sis nws lub neej kev pabcuam yuav raug txo qis hauv thaj chaw ib puag ncig kev lag luam lossis thaj chaw muaj kuab paug loj.
Tsis tas li ntawd txheej PE tiv tsis zoo rau UV tsis kam thiab hmoov ua hauj, yog li kev siv PE txheej txheej tseem xav tau ua kev txwv.
Feem ntau siv rau hauv thaj chaw uas tsis muaj kuab paug rau huab cua tsis txaus ntshai lossis cov khoom lag luam uas xav tau ua ntau zaug.
Txheej txheem:
Substrate:
-Cov tsis haum galvanized steel coils, raws li JIS G3302, Zinc txheej 275 g / m² ；
-Cov dipped galvalume (5% txhuas txheej ntxiv hauv), raws li JISG3317, Zinc txheej: 275 g / m²;
-Hop dipped galvalume (55% aluminium txheej ntxiv hauv), raws li JIS G3321, AZ txheej: 150 g / m², cov txheej txheem tuab: 0.576mm, lwm cov tuab tuaj yeem ua raws li cov neeg siv khoom.
Txheej Primer:
Kev siv cov tshuaj tiv thaiv zoo tiv thaiv Polyurethane (Kuj hu ua PU), zaj duab xis tuab: 5μm.
Txheej sab saum toj:
Siv Kev Ua Zoo Siv thiab txhim kho Polyester, zaj duab xis tuab 20-22μm.
Sab saum toj txheej xim& gloss:
-Cov xim tuaj yeem raug kho;
-Top txheej xim ci ntsa iab feem ntau yog 25%, 35%, 65% lossis 75% (60 ° lub kaum kab rov tav dhau los, raws li ASTM D523)
Tom qab primer txheej:
Kev siv cov tshuaj tiv thaiv zoo tiv thaiv Polyurethane (Kuj hu ua PU), zaj duab xis tuab: 2μm.
Tom qab txheej:
Kev siv cov tshuaj tiv thaiv zoo corrosion epoxy cob txheej, polyester cob txheej, zaj duab xis tuab: 7-10μm.
Tom qab lo xim xim& gloss:
-Back txheej xim feem ntau yog siv cov xim beige, grey lossis dawb grey xim.
-Back txheej gloss feem ntau yog 25% lossis 65% (60 ° lub kaum sab xis, raws li ASTM D523).
