PPGI thiab PPGL yog ob hom pre-painted galvanized steel siv nyob rau hauv ntau yam kev siv. Qhov sib txawv tseem ceeb ntawm PPGI (Pre-Painted Galvanized Iron) thiab PPGL (Pre-Painted Galvalume) yog nyob rau hauv hom txheej siv.
PPGI (Pre-Painted Galvanized Hlau): PPGI yog tsim los ntawm galvanized steel coils uas yog coated nrog ib txheej xim. Cov hlau galvanized yog thawj zaug kho kom tshem tawm cov impurities thiab tom qab ntawd coated nrog primer ua ntej siv cov xim kawg. Cov xim txheej muab xim thiab kev tiv thaiv ntxiv tiv thaiv corrosion.
PPGL (Pre-Painted Galvalume): PPGL, ntawm qhov tod tes, yog tsim los ntawm galvalume steel coils, uas yog coated nrog kev sib xyaw ntawm zinc thiab txhuas. Galvalume yog ib lo lus siv rau steel coated nrog zinc-aluminium alloy. Zoo li PPGI, PPGL kuj yog coated nrog ib txheej xim rau xim thiab kev tiv thaiv.
Qhov sib txawv tseem ceeb ntawm PPGI thiab PPGL:
Txheej Txheej: PPGI siv zinc txheej, thaum PPGL siv zinc-aluminium txheej. Cov txhuas hauv txheej muab kev txhim kho corrosion kuj piv rau PPGI.
Corrosion Resistance: PPGL muaj corrosion kuj zoo dua li PPGI vim muaj txhuas nyob rau hauv txheej. Nws muab kev tiv thaiv ntxiv rau xeb thiab feem ntau nyiam nyob rau hauv ib puag ncig nrog cov av noo siab lossis raug rau cov ntsiab lus hnyav.
Thaum tshav kub kub Resistance: PPGL nyhav kom muaj cua sov zoo dua piv rau PPGI vim yog cov ntsiab lus txhuas hauv txheej. Qhov no ua rau PPGL haum rau cov ntawv thov uas qhov kub tsis kam yog qhov tseem ceeb, xws li vov tsev hauv cov huab cua kub.
Ob leeg PPGI thiab PPGL muaj lawv qhov zoo sib xws thiab siv ntau yam kev siv, suav nrog vov tsev, cladding, khoom siv, thiab cov khoom siv. Qhov kev xaiv ntawm PPGI thiab PPGL nyob ntawm seb cov xwm txheej xws li ib puag ncig, kev nyiam zoo nkauj, thiab kev ua haujlwm tshwj xeeb
