Lub nruas ntim tau hloov zuj zus los ntawm txoj haujlwm ntawm kev khaws cia ib ntus cov ntsiab lus rau niaj hnub no' s ntim khoom lag luam, muag ntim khoom, ntim khoom thauj, thiab lwm yam; sib sau ua ke cov ntim ntws tsis tu ncua los ntawm ntau lawm mus ncig thiab noj tau dhau los ua ib txoj hauv kev rau lub sijhawm ntev cia ntawm cov ntsiab lus. Kev ua haujlwm thiab lub neej tau ua rau muaj kev hloov loj thiab kev nce qib. Ntim nruas muaj cov yam ntxwv hauv qab no:
1. Cov khoom muaj peev xwm ntau, kev siv hluav taws xob thiab cov nqi qis dua. Tsis tas li ntawd, nws muaj kev rov ua dua tshiab thiab yog qhov zoo dua ntsuab ntawm kev tiv thaiv ib puag ncig.
2, kev ua zoo heev, kev siv tshuab ua tiav, kev ua kom txuas mus ntxiv thiab siv tshuab. Nws muaj cov ductility thiab lub zog zoo, thiab tuaj yeem dov mus rau ntau daim phiaj tuab thiab foils. Cov paib tuaj yeem raug ntaus thwj, dov, ncab, thiab welded kom ua cov ntim ntim ntawm cov duab sib txawv thiab ntau thiab tsawg.
3. Nws muaj kev tiv thaiv zoo kawg nkaus. Cov dej vapor kis tus nqi ntawm cov hlau yog tsawg heev, thiab nws yog opaque kiag li, uas tuaj yeem tiv thaiv qhov kev cuam tshuam zoo ntawm kev tiv thaiv ultraviolet rays. Nws cov khoom siv roj-thaiv, noo-pov thawj, pom lub teeb thiab cov txee-lub neej zoo tshaj li lwm yam xws li yas thiab ntawv. Yog li, lub thawv ntim khoom tuaj yeem tswj cov khoom kom zoo ntev, uas yog tshwj xeeb tshaj yog kev ntim khoom noj.
4. Lub thawv ntim khoom siv tau tshwj xeeb xim hlau, thiab nws kuj yog qhov yooj yim luam tawm thiab dai kom zoo nkauj, uas tuaj yeem ua rau cov khoom lag luam zoo nkauj, zoo nkauj thiab ua lag luam.
5. Lub thawv ntim khoom tau muaj cov yam ntxwv zoo thiab muaj lub zog siab, yog li lub thawv ntim khoom ntim tau tuaj yeem ua rau nyias-phab ntsa, muaj qhov ua kom muaj zog, thiab tsis yooj yim ntim cov thawv ntim khoom. Nyob rau hauv txoj kev no, kev nyab xeeb ntawm cov khoom ntim tau txais kev lees paub, thiab nws yooj yim khaws, thauj, thauj khoom thiab thau tawm thiab siv.https: //www.fhpails.com/
