Cov khoom ntawm qhov muab tub lim tau muab faib ua peb pawg: ceramic, hlau thiab yas.
1. Tej hub lim muaj cov zoo corrosion thiab kub tsis kam. Tej hub dej tsis puv thiab muaj cov nplaim dej zoo nkauj zoo nkauj. Lawv nkig thiab tsis yooj yim. Nws nquag siv hauv cov txheej txheem xws li kev nqus pa, kev ntxuav roj, thiab kev ua kua tawm.
2. Lub tshuab ua hlau tau tuaj yeem ua cov khoom sib txawv, thiab kev xeb yog qhov kev txiav txim siab tseem ceeb thaum xaiv. Cov pa roj carbon steel cav tsis tshua muaj nqi thiab muaj cov nplaim dej zoo nkauj. Lawv yuav tsum tau siv nyob rau hauv qhov kev nyiam ntawm cov khoom tsis muaj corrosive lossis qis-kho; stainless steel sau muaj muaj zog corrosion tsis kam thiab feem ntau tiv thaiv qhov kev txhim kho corrosion ntawm cov ntaub ntawv tsis tshua dhau Cl-, tab sis lawv tus nqi yog siab heev, thiab qhov chaw ntub dej tsis zoo. Qee qhov chaw tshwj xeeb (xws li cov txheej txheem nqus dej ua haujlwm raws li cov tshuaj tsuag qis heev) yuav tsum tau kho rau saum npoo kom ua tiav cov txiaj ntsig zoo; titanium, tshwj xeeb alloys Fillers ua los ntawm cov hlau thiab lwm yam ntaub ntawv yog kim thiab feem ntau tsuas yog siv hauv cov khoom siv txhim kho. Feem ntau hais lus, cov hlau ntim tau ua rau cov phab ntsa nyias nyias, nrog cov flux loj loj, roj tsis kam, thiab siab cuam tshuam. Lawv tuaj yeem siv hauv qab kub, tiv thaiv kev kub siab, thiab muaj peev xwm tiv tau zoo, thiab muaj ntau yam siv.
3. Yas muab tub lim Cov khoom ntawm yas muab tub lim feem ntau suav nrog polypropylene (PP polyethylene (PE thiab polyvinyl chloride (PVC, thiab lwm yam, thiab lwm yam)), polypropylene feem ntau siv. Kev xeb nrog cov kuab tshuaj organic. Nws muaj qhov kub thiab txias tsis zoo thiab tuaj yeem siv qis dua 100 ° C rau lub sijhawm ntev. Cov yas ntim khoom yog lub teeb, pheej yig, muaj cov tawv tawv zoo, cuam tshuam, tsis tawg yooj yim, thiab tuaj yeem ua rau cov txheej txheem nyias-ntsa .Qhov loj flux, Kev txo qhov siab, feem ntau siv rau hauv kev nqus, desorption, rho tawm, plua plav tshem tawm thiab lwm yam khoom siv.
