Txias yob
PPGI (xim-coated galvanized steel ntawv) yog lub khaub thuas txias. PPGi yog cov ntawv txias-dov steel nrog cov organic txheej rau saum npoo. Hom coating muaj xws li PE, SMP, PVDF, thiab lwm yam khoom siv tau zoo, thiab yog siv tau zoo nkauj, cov khoom siv hauv tsev, tsheb thauj mus los thiab lwm thaj chaw.
Cov txheej txheem ntau lawm ntawm PPGi suav nrog ob kauj ruam tseem ceeb: colding txias thiab galvanizing. Ua ntej tshaj, lub kub-rolled steel sawb yog pickled kom tshem tawm cov chaw oxide; Tom qab ntawd nws txias dov kom ua tiav qhov uas yuav tsum tau tuab los ntawm ntau cov dov hla; Tom qab ntawd annealing yog ua los txhim kho kev ua kev ua haujlwm ntawm cov hlau txaij; Thaum kawg, Galvanizing yog ua, feem ntau yog siv cov txheej txheem txuas ntxiv mus npog saum npoo ntawm cov ntawv siv steel nrog rau kev txhim kho nws txoj kev txhim kho corrosion.
PPGI muaj cov cuab yeej siv hauv tsev, suav nrog cov khoom siv hauv tsev, tsheb thauj khoom, thiab nws muaj huab cua tsis zoo thiab muaj huab cua zoo tsis kam thiab muaj kev ruaj khov.
