Cov khoom siv raw ntawm PE yeeb nkab yog polyethylene yas, uas yog cov yas yooj yim tshaj plaws, yog li nws feem ntau hu ua "PE". Tej zaum koj tseem tsis paub ntau txog qhov no, tab sis qhov tseeb, cov khoom siv raw zoo li no tseem muaj ntau heev hauv lub neej, xws li: hnab yas, hnab yas thiab lwm yam khoom siv niaj hnub ua los ntawm nws.
1. Lub neej ntev corrosion kuj: nyob rau hauv cov chaw uas muaj cov av noo siab, yog siv cov kav dej steel, txawm tias kev tiv thaiv corrosion, lub neej kev pab tsuas yog 30 xyoo, tab sis PE kav dej tuaj yeem ua tiav ntau tshaj 50 xyoo!
2. Lub cev muaj zog: PE yeeb nkab belongs rau nruab nrab ntom ntom polyethylene, thiab tib lub sijhawm, nws yog lub teeb nyob rau hauv qhov hnyav, yooj yim rau kev tsim cov nqi tsheb thauj mus los.
3. Tus nqi tsim nyog: Ntxiv rau qhov kev pab cuam lub neej ntev uas tau hais hauv thawj lub ntsiab lus, cov phab ntsa sab hauv ntawm PE yeeb nkab yog du thiab tsis scale, uas feem ntau tuaj yeem txo cov peev hauv qhov project thiab txo tus nqi zoo heev.
4. Kev sib txuas yooj yim: Thaum lub raj xa dej ntev ntev, cov yeeb nkab coil tuaj yeem siv los nteg cov PE yeeb nkab trench, uas yog qhov zoo dua li ntawm cov yeeb nkab steel trench, thiab thaum cov kev tsim kho yog txwv, electrofusion vuam siv tau. Tsis tas li ntawd, cov txheej txheem ntawm submerging cov yeeb nkab tuaj yeem siv los tso rau hauv qab ntawm cov dej, uas txo cov kev tsim kho nyuaj thiab cov nqi tsim khoom.
