Cov ntaub hlau yog cov cuab yeej nquag ua hauv kev ua liaj ua teb, ua teb, kev lag luam, thiab kev tu tsev. Cov kev xaiv xaiv ncaj qha cuam tshuam cuam tshuam rau lawv cov kev ruaj khov, kev nyab xeeb, thiab muaj cov xwm txheej muaj feem xyuam. Nkag siab cov ntaub ntawv tseem ceeb thiab cov yam ntxwv ntawm cov tshuaj tsuag yog qhov tseem ceeb rau cov tuam txhab lag luam kev lag luam thiab ua kom lawv cov khoom kom muaj kev sib tw ua lag luam.
Tam sim no, cov ntaub so txau cov ntaub ntawv ntawm kev ua lag luam tuaj yeem faib ua peb hom tseem ceeb: yas, hlau, thiab cov khoom siv puas. Cov tshuaj yas siv hluav taws xob yas yog qhov dav tshaj plaws vim lawv lub teeb, corrosionight, corrosion {{1} {{- tus nqi. Cov khoom siv yas muaj cov polyethylene (PE), polypropylene (PP), thiab polyvinyl chloride (PVC). PE thiab PP yog qhov tsim nyog rau cov tshuaj txau ntau, feem ntau yog cov tshuaj tua kab thiab chiv, vim lawv cov tshuaj ruaj khov zoo thiab cuam tshuam. PVC, vim nws lub zog siab dua, feem ntau siv nyob rau hauv industrial- kev ua tau zoo, tab sis nws cov kev ua tau zoo dua, txwv nws siv hauv qee lub khw.
Hlau txau hlau, feem ntau ua los ntawm cov hlau stainless thiab aluminium alloy, muab rau ntau dua kev siv taus, ua rau lawv haum rau kev txau siab- qhov siab. Stainless hlau txha zaub hlau tau siv dav hauv kev kho mob thiab tu cov ntaub ntawv, cov ntawv tuaj yeem nrov dua rau cov ntawv thov sab nraum zoov thiab mobile vim yog lawv lub teeb yuag. Txawm li cas los xij, cov ntaub ntawv hlau kim thiab raug rau oxidation, feem ntau xav tau ntxiv Rust {}} e} Est cov nqi ntau lawm.
Nyob rau hauv xyoo tsis ntev los no, cov tshuaj tsuag tshuaj kuab quav tau dhau los ua neeg nyiam. Los ntawm kev sib txuas nrog cov yas ua ke nrog cov khoom siv uas siv tau cov iav fiber ntau thiab carbon fiber ntau, lawv muaj cov yas lub teeb ci thaum txhim kho nws lub zog thiab tshuaj lom neeg. Cov ntaub ntawv no feem ntau siv rau hauv high-}}}}} Cov ntaub ntawv ua liaj ua teb lossis cov ntawv thov tshwj xeeb. Thaum lawv kim dua, lawv muab cov txiaj ntsig tseem ceeb hauv kev ua phooj ywg thiab ib puag ncig ib puag ncig.
Rau cov tuam txhab ua lag luam tawm txawv teb chaws yuav tsum muaj kev txiav txim siab ntawm cov kev xav tau kev lag luam kev lag luam, kev txwv tsis pub muaj nuj nqis, thiab tus nqi. Piv txwv li, cov lag luam hauv tebchaws Europe thiab Asmeskas muaj cov ntaub ntawv ua kom nruj ib puag ncig, ua rau yas thiab stainless hlau yooj yim kom muaj ntawv pov thawj. Lub caij no, cheeb tsam xws li Southeast Asia thiab Africa xub thawj tus nqi- ua rau cov tshuaj khib nyiab yas ua tau zoo dua. Nkag siab cov khoom siv thiab raug rau lawv rau kev lag luam thov lag luam yog qhov tseem ceeb los txhim kho cov khoom lag luam thoob ntiaj teb kev sib tw.
