Raws li cov khoom tseem ceeb hauv kev tsim hluav taws xob niaj hnub tsim, yas} Nkag siab txog lawv cov khoom siv thawj cov khoom muaj pes tsawg leeg yog qhov tseem ceeb kom nkag siab cov yam ntxwv ntawm cov khoom lag luam no.
Los ntawm cov txheej txheem tseem ceeb, yas - txheej txheem hlau los yog qis} {}}} lub zog steel. Tsim los ntawm cov dov txias lossis kub tsis tsuas yog muaj lub zog compressive zoo tab sis kuj yoog kom haum rau cov kev teeb tsa hauv kev teeb meem geological. Cov qeb steel xws li Q235B thiab Q345B yog cov ntaub ntawv hauv paus rau yas rau lawv cov nqi zoo heev}} ua hauj lwm zoo. Cov pa roj carbon steel substrates tau dhau los ua ntej - kev kho kom tshem tawm cov kab oxide txheej, tsim kom zoo tshaj plaws rau cov txheej txheem ntxiv.
Nyob rau hauv cov nqe lus ntawm kev ua haujlwm ua haujlwm, yas- co coated steel kav yog feem ntau nrog thermoplastics lossis thermosetting resins. Sab hauv txheej yog feem ntau ua los ntawm cov zaub mov- qib qib polyethylene (PE) lossis epoxy cob (Epoxy Resin (EP). Siab -} ceev polyethylene muaj cov tshuaj ruaj khov zoo heev thiab muaj txiaj ntsig zoo rau acidic thiab alkaline corrosive media. Epoxy hmoov txheej, vim nws cov qauv molecular, cov khoom pov thawj zoo nkauj zoo nkauj thaum thauj cov dej haus. Cov txheej txheej tiv thaiv sab nraud yog feem ntau ua los ntawm U6 {}} tsis kam hloov cov kev laus thiab tawg thaum ub siv.
Cov ntawv thov tshwj xeeb tshwj xeeb tau ua rau txoj kev txhim kho kev txhim kho tshiab ntawm cov khoom siv. Txhawm rau kom tau raws li qhov xav tau ntawm high - Cov khoom siv dej kub siv tau kub (pp {}} r) raws li sab hauv. Rau kev hnav tsis kam nyob rau hauv cov ntawv thov tsuas yog ntxiv ntxiv ceramic hais tau txuas cov yeeb nkab service los ntawm 3 {{}} 5 zaug. Cov khoom siv no txhim kho lub siab xam phaj-cov kab mob zoo ntawm cov kav hlau steel thaum muab kev ua haujlwm tshwj xeeb rau kev ua haujlwm tshwj xeeb.
Los ntawm kev ua lag luam thoob ntiaj teb, cov khoom siv ntawm cov yas -} coated steel kav ncaj qha cuam tshuam ncaj qha rau cov khoom lag luam export sib tw. Material formulations that comply with international standards such as ASTM and ISO, coupled with SGS-certified material testing reports, have become a key to gaining access to high-end markets in Europe and the United States. Txog kev lag luam tawm xws li Southeast Asia thiab Middle East, cov khoom sib xyaw ua ke zoo nqi uas muaj txiaj ntsig zoo nqi nrog cov kev ua tau zoo dua nyiam cov neeg yuav khoom.
Nkag siab cov ntsiab lus ntawm cov khoom siv ntawm cov khoom lag luam kev lag luam tshwj xeeb tab sis kuj tau pom cov khoom lag luam tshwj xeeb hauv kev ua lag luam hauv kev ua lag luam thoob ntiaj teb.
