Cov tsis xws luag feem ntau muaj xws li: ntog tawm, khawb, passivation me ntsis, zinc hais, tuab npoo, cua riam kab txaij, cua riam khawb, raug hlau, inclusions, mechanical puas, tsis zoo ntawm steel puag, wavy npoo, ladles, loj loj, embossing, tsis tsim nyog thickness ntawm zinc txheej, cov menyuam luam ntawv, thiab lwm yam.
Lub ntsiab yog vim li cas rau zinc txheej ntog tawm yog: nto oxidation, silicon tebchaw, heev qias neeg txias dov emulsion, siab oxidation cua nyob rau hauv NOF seem thiab lwg point ntawm cov roj tiv thaiv, tsis tsim nyog huab cua-roj piv, tsawg hydrogen txaus, oxygen infiltration nyob rau hauv lub Rauv, tsis tshua muaj kub ntawm sawb hlau nkag mus rau hauv lub lauj kaub, tsis tshua muaj cua sov siab nyob rau hauv RWP seem thiab cua suction nyob rau hauv lub qhov rooj rauv, qhov cub tsis kub nyob rau hauv NOF seem, tsis muaj roj evaporation, tsawg txhuas cov ntsiab lus nyob rau hauv zinc lauj kaub, ceev ceev chav tsev ceev, tsis txaus txo, Lub sijhawm nyob luv luv hauv cov kua zinc Cov txheej yog tuab heev.
