Cov ntaub ntawv ntau lawm rau cov roj yas nplaum-coated sib xyaw ua ke feem ntau muaj ob ntu: substrate thiab cov ntaub ntawv txheej.
Substrate
Cov yeeb nkab steel: raws li lub cim tseem ceeb rau cov kav dej yas-coated sib xyaw, cov kav dej hlau yuav tsum muaj cov khoom siv zoo thiab weldability. Cov khoom siv ntawm cov kav dej hlau tuaj yeem xaiv raws li kev siv kev siv tshwj xeeb, xws li siv cov qauv hlau feem ntau xws li Q235b thiab Q345B. Lub cheeb, phab ntsa thickness, thiab lwm yam kev qhia tshwj xeeb ntawm cov kav hlau hlau kuj yuav tsum tau txiav txim siab raws cov khoom tsim qauv.
Cov Khoom Txheej Txheej
Yas Hmoov: Qhov feem ntau suav nrog thermoplastic lossis thermoset yas hmoov xws li polyethylene (PE) thiab epoxy cob (Epoxy Resin (EP). Cov ntaub ntawv no ua rau muaj kev tiv thaiv corrosion zoo tshaj plaws, kev tiv thaiv kev tiv thaiv, thiab cov nplaum, uas yog qhov tseem ceeb rau kev xeb tawm ntawm cov roj av yas.
Polyethylene (PE): Vim nws cov khoom siv kub tsis kam, cov tshuaj tsis ruaj khov, thiab hluav taws xob rwb thaiv tsev, PE yog dav siv hauv kev tsim cov yas-coated composite pipes.
Epoxy Resin (EP): Nrog nws cov khoom siv tshuab ua zoo thiab muaj hluav taws xob kev quab yuam ua, EP kuj yog ib qho ntawm cov khoom siv txheej yas-coated sib xyaw ua ke kav.
Lwm cov ntaub ntawv ib pab pawg: Lub sijhawm cov txheej txheem ntau lawm ntawm cov kav dej yas cov kav dej tseem yuav tau, xws li cov neeg sawv cev thiab cov tshuaj tua neeg. Cov ntaub ntawv no feem ntau yog siv los kho cov khoom ntawm txheej txheej txheej lossis txhim kho txheej txheem txheej txheej txheej txheej.
