PPGI Roofing Sheet Xim yog dab tsi?
PPGI (Pre-Painted Galvanized Iron) cov ntawv vov tsev yog txias- dov steel coils coated nrog zinc txheej thiab tom qab ntawd pleev xim rau cov organic coatings. Cov xim yog cov xim pleev xim rau saum cov primer, thiab nws txhais tau hais tias ob qho tib si lub ntsej muag ntawm lub tsev thiab, ua ke nrog cov txheej txheej, ntev npaum li cas lub ru tsev khaws nws cov tsos.

Nws yog xim hlau thiab pearlescent tiav: coatings nrog txhuas los yog mica pigments uas muab ib tug hlau -zoo li nto.
Kev cai xim: sib phim rau tus neeg siv khoom RAL lossis Pantone siv, feem ntau nrog qhov tsawg kawg nkaus kom muaj nuj nqis.
Xim Systems siv hauv kev lag luam
Feem ntau cov neeg muag khoom PPGI sib phim xim rau RAL Classic system, thiab cov phiaj xwm vov tsev loj feem ntau qhia cov lej Pantone lossis Suav GB / T 13448 xim qauv rau kev kuaj txheej. Thaum koj xaj, hais tus lej RAL ntau dua li lub npe xim, vim tias cov npe xws li "ntsuab xiav" txawv ntawm cov tuam txhab.
Yuav ua li cas txheej hom cuam tshuam xim thiab kav ntev
| Txheej resin | Hom kev siv | Xim khaws cia |
|---|---|---|
| Polyester (PE) | Nyiaj txiag vaj tsev nyob | 3-5 xyoos tsis muaj chalking tseem ceeb |
| Silicone hloov polyester (SMP) | Cov tsev lag luam | Zoo dua UV tsis kam |
| PVDF (polyvinylidene fluoride) | Ntug hiav txwv thiab siab -UV cheeb tsam | Kev khaws cia ntev tshaj plaws, 20+ xyoo |
Zinc txheej thickness (feem ntau Z80 rau Z275 ib GB / T 2518) thiab primer kuj tseem ceeb: yog tias cov galvanized substrate nyias dhau lawm, xeb tshwm ntawm qhov txiav thiab cov xim tev tawm thaum ntxov.
