Kev xaiv cov khoom siv rau kev sib cais rooj vag steel pwm muaj qhov cuam tshuam tseem ceeb ntawm cov pwm kev ua haujlwm, kev pabcuam lub neej, thiab tus nqi. Tam sim no, ob qho khoom siv feem ntau rau kev sib cais rooj vag steel pwm ntawm kev ua lag luam yog:
Q235 Steel Phaj: Q235 steel phaj yog cov khoom siv feem ntau siv rau kev sib cais rooj vag hlau pwm. Nws muaj cov yas zoo thiab tawv tawv, txhais tau hais tias nyob rau hauv chav tsev kub, nws tuaj yeem ua tau yooj yim los ntawm ntau yam haujlwm xws li txiav, khoov, thiab vuam, ua kom yooj yim rau pwm tsim. Nyob rau tib lub sijhawm, Q235 steel phaj muaj lub zog nruab nrab, muaj peev xwm tiv taus lub siab tsim thaum lub sij hawm molding txheej txheem, kom ntseeg tau tias cov pwm tsis yooj yim deformed los yog puas thaum siv, yog li ncua nws cov kev pab cuam lub neej. Tsis tas li ntawd, Q235 steel phaj kuj pheej yig, pab txo cov nqi tsim khoom thiab txhim kho kev lag luam.
Stainless Hlau Phaj: Hauv qee daim ntawv thov uas xav tau kev tiv thaiv corrosion siab, stainless hlau phaj dhau los ua cov khoom nyiam. Stainless hlau phaj muaj zoo heev corrosion kuj, tso cai rau nws siv rau ncua sij hawm nyob rau hauv cov huab cua puag nrog corrosive tshuaj tsis yooj yim rusting los yog puas. Qhov no muab stainless hlau cais rooj vag hlau moulds lub neej ntev kev pab cuam thiab ruaj khov kev ua tau zoo nyob rau hauv tshwj xeeb ib puag ncig.
Txawm li cas los xij, stainless hlau daim hlau kuj tseem kim, yog li txwv lawv daim ntawv thov; lawv feem ntau tsuas yog siv rau hauv cov xwm txheej uas xav tau kev ua haujlwm pwm tshwj xeeb.
Thaum xaiv cov khoom siv rau cov pwm steel rau cov teeb meem kev tsheb khiav, kev xav txog kev ua haujlwm tshwj xeeb thiab qhov yuav tsum tau ua. Yog tias qhov chaw ua haujlwm hnyav thiab yuav tsum muaj kev tiv thaiv corrosion, stainless hlau daim hlau yog qhov kev xaiv zoo; Yog tias qhov chaw ua haujlwm tau zoo thiab tus nqi yog qhov kev txhawj xeeb, Q235 steel daim hlau yog qhov tsim nyog dua.
