Xim-coated coils yog cov khoom tsim los siv cov substrates xws li kub-dip galvanized steel, kub-dip aluminium-zinc alloy steel, electro-galvanized steel, txias-rolled steel, thiab aluminium-zinc alloy steel. Ua raws li kev kho saum npoo av-xws li tshuaj degreasing, phosphating, passivation, thiab tshuaj hloov pauv tshuaj-ib lossis ntau txheej txheej ntawm cov organic coatings yog siv rau saum npoo ntawm cov txheej txheem xws li cov menyuam txheej lossis cov tshuaj tsuag txheej, tom qab ntawd cov khoom siv tau ci thiab kho. Cov khoom no muab lawv lub npe los ntawm kev siv cov organic coatings hauv ntau xim, thiab lawv feem ntau hu ua "xim-coated coils."
Kev tsim kho kev lag luam yog cov neeg siv khoom lag luam loj tshaj plaws rau cov xim -coated coils, suav txog kwv yees li 80% ntawm tag nrho cov khoom siv. Nyob rau hauv xyoo tas los no, lub peev xwm ntau lawm ntawm Tuam Tshoj cov xim -coated coil kev lag luam tau txuas ntxiv nthuav dav, nce los ntawm 51.09 lab tons hauv 2021 txog 55.12 lab tons hauv 2024. Txawm li cas los xij, kev siv peev xwm tseem qis dua - sawv ntawm 43.71% hauv 2024-qhov teeb meem ntawm kev lag luam ntau dhau. Tsis tas li ntawd, kev lag luam muaj peev xwm ntau lawm yog thaj chaw muaj zog, nrog rau East Tuam Tshoj thiab North Tuam Tshoj cheeb tsam sib sau ua ke rau ntau dua 80% ntawm lub teb chaws tag nrho cov peev txheej thiab cov khoom tsim tawm.
