Prepainted Steel Coil (PPGI, PPGL) Coating type
2/1: Yakapendwa kaviri pamusoro pepamusoro, kamwe kumashure, uye yakabikwa kaviri.
Application:Kupokana necorrosion uye scratch resistance yependi ye-single-layer back paint haina kunaka, asi ine good adhesion.Kuzoiswa kune sandwich panels;
2/1M: Pendi yepamusoro neyekumashure nzvimbo kaviri imwe neimwe, uye yakabikwa kamwe.
Application:Iyo pendi yekumashure ine yakanaka corrosion kuramba, kukwenya kuramba uye kugadzirisa formability, uye ine yakanaka adhesion.Iyo yakakodzera kune imwechete laminated board uye sandwich board.
2/2: Pendi yekumusoro neyekumashure nzvimbo kaviri imwe neimwe, uye bikai kaviri.
Application: Iyo kaviri-layer kumashure pendi ine zvirinani kusagadzika kwecorrosion, kukwenya kuramba uye kugadzirisa formability.Mazhinji acho anoshandiswa kune imwechete laminated board, asi kunamatira kwayo hakuna kunaka, haina kukodzera sandwich board.
