Cov hlau phaj xim yog cov khoom ua los ntawm cov hlau phaj txias thiab cov hlau phaj galvanized ua cov khoom siv, tom qab kho qhov chaw ua ntej, siv cov txheej txheem tooj liab + cov txheej txheem ci, txheej nrog txoj kev txuas ntxiv mus, ci thiab txias. Muaj ntau hom xim phaj substrates, xws li kub-dip galvanized xim phaj, electro-galvanized xim phaj, kub-dip galvanized xim phaj, txias-dov substrate xim phaj, thiab lwm yam. Cia peb saib.
Cov hom ntaub ntawv tseem ceeb rau cov phaj xim yog:
1. Cov hlau phaj uas muaj xim txheej txheem txias
Cov phaj xim uas tsim los ntawm lub phaj hauv paus txias-dov muaj qhov zoo nkauj thiab du, thiab muaj kev ua haujlwm ntawm lub phaj txias-dov; tab sis txhua qhov khawb me me ntawm qhov txheej txheem saum npoo yuav ua rau lub phaj hauv paus txias-dov mus rau saum huab cua, yog li cov hlau uas raug nthuav tawm yuav sai sai tsim cov xeb liab. Yog li ntawd, hom khoom no tsuas yog siv tau rau kev ntsuas ib ntus thiab cov ntaub ntawv sab hauv tsev uas muaj qhov yuav tsum tau ua qis.
2. Cov hlau phaj uas muaj xim kub-dip galvanized
Cov khoom tau los ntawm kev siv cov txheej txheem organic rau ntawm cov hlau galvanized kub-dip yog cov hlau galvanized xim-coated. Ntxiv rau qhov kev tiv thaiv ntawm zinc, cov hlau galvanized kub-dip kuj muaj cov haujlwm ntawm kev tiv thaiv rwb thaiv tsev thiab tiv thaiv xeb, thiab lub neej ua haujlwm ntev dua li cov hlau galvanized kub-dip. Cov ntsiab lus zinc ntawm cov khoom siv galvanized kub-dip feem ntau yog 180g / mr (ob sab), thiab cov ntsiab lus galvanized siab tshaj plaws ntawm cov khoom siv galvanized kub-dip rau sab nraud ntawm lub tsev yog 275g / m2.
