Cov kev pabcuam lub neej ntawm cov kev sib txawv vim nws cov khoom siv, siv cov haujlwm thiab ua haujlwm. Hauv qab no yog ib qho kev qhia txog lub neej ntawm ntau hom kev sib tw:
Stainless Hlau Lwj
Nyob rau hauv ib puag ncig huab cua (xws li kub siab, kev kub siab lossis muaj zog corrosion), cov kev pabcuam lub neej yog hais txog 5-7 xyoo.
Nyob rau hauv ib puag ncig zoo, lub neej pabcuam tuaj yeem txuas ntxiv rau 15 xyoo.
Hlau Lwj
Feem ntau, cov kev pabcuam lub neej ntev dua, nce mus txog ntau tshaj 10 xyoo, tab sis lub neej tshwj xeeb nyob ntawm kev siv ib puag ncig thiab saib xyuas.
HDPE Muab Khaub Ncaws Hnav
Txais yuav High-Density Polyethylene (HDPE), nws muaj cov khoom siv tiv thaiv corrosion, thiab kev pabcuam kev pabcuam feem ntau tsis tsawg tshaj 50 xyoo.
Txawm li cas los xij, nyob rau ib puag ncig nrog cov muaj kuab acidity thiab alkalinity, kub siab lossis lub nra hnyav, lub neej pabcuam yuav raug txo kom tsawg.
304 roj rellows
Siv tshwj xeeb hauv kev thaj teb roj av, nws muaj cov yam ntxwv ntawm kev tawm tsam kev laus, kev ua kom corrosion kuj, thiab lwm yam kev pabcuam lub neej tuaj yeem nce txog 50 xyoo.
Yas taub
Qhov kev pabcuam lub neej yog tsis tshua muaj luv, feem ntau txog 5 xyoos, thiab tej zaum yuav luv luv nyob rau hauv ib puag ncig hnyav.
Ntsiab lus: Lub neej ntawm rellows li ntawm 5 txog 50 xyoo, nyob ntawm cov khoom (xws li stainless hlau, HDPE), kev siv kub, corrosiveness) thiab txij nkawm. Xaiv cov khoom siv yog thiab kev saib xyuas ib txwm muaj yog tus yuam sij pheej ncua lub neej ntawm lub neej ntawm lub neej.
