Muab faib los ntawm Kev Tsim Khoom Siv

Cov ntaub ntawv tsim khoom xa mus rau cov khoom siv rau cov khoom tseem ceeb ntawm cov thawv ntim khoom (sab phab ntsa, phab ntsa kawg, sab saum toj, thiab lwm yam), uas tuaj yeem muab faib ua peb hom: thawv steel, aluminium alloy ntim, fiberglass ntim, ntxiv rau cov thawv ntoo, stainless hlau ntim, thiab lwm yam ntawm lawv: steel ntim, ua los ntawm cov hlau, muaj qhov zoo ntawm lub zog siab, cov qauv ruaj khov, siab weldability, zoo dej nruj, thiab tus nqi qis; Qhov tsis zoo yog qhov hnyav hnyav thiab tsis zoo corrosion kuj; Aluminium alloy thawv, ua los ntawm cov khoom siv aluminium alloy, muaj qhov zoo ntawm lub teeb yuag, zoo nkauj tsos, corrosion kuj, zoo elasticity, yooj yim ua, tsawg ua thiab kho cov nqi, thiab lub neej ntev kev pab cuam; Qhov tsis zoo yog tus nqi siab thiab kev ua haujlwm vuam tsis zoo;
Fiberglass ntim, ua los ntawm cov khoom siv fiberglass, muaj qhov zoo ntawm lub zog siab, zoo rigidity, loj cov ntsiab lus tsub zuj zuj, zoo rwb thaiv tsev, anti-corrosion, tshuaj tiv thaiv, yooj yim tu, thiab kho yooj yim; Qhov tsis zoo yog tias nws hnyav, nws yooj yim rau kev laus, thiab lub zog poob qis ntawm qhov taw tes ntawm kev zawm lub bolt.
