PPGI, los yog pre-painted galvanized hlau, yog ib tug nrov coated steel khoom siv nyob rau hauv ntau yam kev siv, xws li vov tsev thiab siding rau tsev thiab kev lag luam. Raws li nrog rau txhua yam khoom, muaj cov qauv uas yuav tsum tau ua rau PPGI coils kom ntseeg tau tias lawv zoo thiab kev ntseeg tau.
Ib qho ntawm cov qauv tseem ceeb tshaj plaws rau PPGI coils yog lawv cov tuab. Cov coils uas nyias dhau yuav tsis muab qhov tsim nyog ruaj khov thiab tiv thaiv cov ntsiab lus, thaum coils uas tuab dhau yuav nyuaj rau kev ua haujlwm nrog thiab yuav tsis muab kev pom zoo. Yog li ntawd, nws yog ib qho tseem ceeb los xyuas kom meej tias PPGI coils raug tsim los rau qhov tsim nyog thickness specifications.
Lwm tus qauv tseem ceeb rau PPGI coils yog lawv cov txheej txheem zoo. Txhawm rau muab cov kav ntev ntev thiab tsis kam tiv thaiv corrosion, PPGI coils yuav tsum tau coated nrog cov khoom tiav zoo uas yog ob qho tib si zoo nkauj thiab tiv thaiv. Txheej txheej txheem zoo tuaj yeem sib txawv nyob ntawm qhov tshwj xeeb daim ntawv thov uas PPGI coil yog npaj, tab sis lawv feem ntau suav nrog cov khoom xws li adhesion, hardness, thiab tsis kam rau chalking thiab fading.
Ntxiv rau qhov tuab thiab txheej zoo, PPGI coils yuav tsum ua tau raws li lwm cov qauv ntsig txog lawv cov tsos thiab kev ua haujlwm. Cov no tuaj yeem suav nrog cov qauv rau xim sib xws, tiaj tus, thiab qhov tseeb qhov tseeb, nrog rau ntau yam khoom siv xws li lub zog thiab ductility.

Nov yog qee cov qauv lees paub ntawm PPGI coils:
1. Thickness: PPGI coils feem ntau muaj qhov tuab ntawm {{{0}}}.12mm txog 1.0mm, thiab nws cov qib siab siab yuav tsum nyob rau hauv ± 0.02mm kom ntseeg tau tias zoo ib yam.
2. Zinc txheej: Zinc txheej tsis tsuas yog muab kev tiv thaiv xeb thiab corrosion tab sis kuj txhim kho tag nrho cov tsos ntawm PPGI coils. Lub zinc txheej hnyav yuav tsum nyob rau hauv thaj tsam ntawm 30g / m² txog 275g / m², raws li daim ntawv thov tshwj xeeb.
3. Xim khaws cia: PPGI coils yuav tsum muaj cov xim zoo heev khaws cia lawv cov kev zoo nkauj rau lub sijhawm ntev. Cov txheej yuav tsum tsis muaj cov cim ntawm kev tawg, tev, lossis fading thaum lub sijhawm teev tseg.
4. Glossiness: Lub glossiness lossis ci ntawm PPGI coils yog qhov tseem ceeb hauv kev txhim kho lawv qhov kev pom zoo tag nrho. Tus nqi gloss yuav tsum nyob hauv thaj tsam ntawm 40 txog 80 GU (Gloss Units) kom ua tiav qhov xav tau.
5. Kev tiv thaivlos cuam tshuam: PPGI coils yuav tsum muaj zog txaus los tiv thaiv kev cuam tshuam lossis kev puas tsuaj rau lub cev thaum lub sijhawm thauj mus los, tuav, lossis kev teeb tsa. Cov txheej yuav tsum tsis muaj cov cim ntawm flaking lossis chipping tom qab qhov kev ntsuam xyuas cuam tshuam.
6. Adhesion: PPGI coils yuav tsum muaj cov khoom adhesion zoo heev los xyuas kom meej tias cov txheej txheem adheres zoo rau cov hlau substrate. Cov txheej txheej yuav tsum dhau qhov kev ntsuas hla hla thiab tsis muaj cov cim qhia ntawm delamination.
7. Yooj yim: PPGI coils yuav tsum tau hloov pauv tau los tiv thaiv kev deformation lossis dabtsi yog khoov uas yuav tshwm sim thaum lub sijhawm tsim khoom. Cov txheej yuav tsum tsis txhob tawg los yog tev thaum raug khoov.
8. Tshuaj tiv thaiv: PPGI coils yuav tsum muaj cov tshuaj tiv thaiv siab, tshwj xeeb tshaj yog acids thiab alkalis, tiv thaiv corrosion thiab deterioration ntawm txheej. Cov txheej yuav tsum dhau qhov kev sim tshuaj tiv thaiv raws li kev lag luam tus qauv.
SIV Standard PPGI COILS:
1. ASTM A653 / A653M / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / A653M / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653 / ASTM A653) thiab ASTM A653: Cov txheej txheem no qhia txog cov kev xav tau ntawm cov ntawv hlau, zinc-coated (galvanized) lossis zinc-hlau alloy-coated (galvannealed) los ntawm cov txheej txheem kub-dip, rau PPGI coils.
2.JIS G3312: Qhov no yog tus qauv Japanese uas qhia txog cov ntawv prepainted kub-dip zinc-coated steel ntawv thiab coils uas yog siv rau architectural thiab industrial daim ntaub ntawv.
3. TS EN 10169: Qhov no yog European tus qauv uas txhais cov kev cai rau cov organic coated tsis tu ncua (coil coated) tiaj tus hlau cov khoom siv rau sab nrauv.
4. GB/T 12754: Qhov no yog tus qauv nyob rau hauv Suav teb uas qhia txog cov prepainted steel daim hlau thiab coils siv rau vov tsev thiab cladding systems.
5.TIAB SA 14246: Cov txheej txheem Indian no muab cov kev cai rau prepainted galvanized steel nplooj ntawv thiab coils rau sab hauv thiab sab nrauv tsev tsim, khoom siv, thiab lwm yam.
Nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov qauv no kom ntseeg tau tias PPGI coils yog cov khoom zoo thiab ua tau raws li qhov yuav tsum tau ua rau lawv xav siv. Los ntawm kev siv cov qauv no los ua cov lus qhia, cov tuam txhab tsim khoom tuaj yeem tsim cov PPGI coils uas ua tau raws li cov kev xav tau ntawm lawv cov neeg siv khoom, ua rau cov neeg siv khoom txaus siab ntau dua thiab kev vam meej hauv kev lag luam.
