Cov khoom lag luam raw rau PE hnab yog polyethylene (PE), ib lub thermoplastic resin ua los ntawm polymerizing ethylene. Kev lag luam muaj, qhov no tseem suav cov ntawv sau txog cov ethylene nrog me me ntawm-}} okefins. Polyethylene muaj cov khoom zoo heev, ua rau haum raws li lub hnab ntim khoom. Nws muaj tshuaj lom neeg zoo heev thiab tiv taus feem ntau cov acids thiab cov hauv paus, tab sis tsis muaj kev tiv thaiv oxidizing acids. Polyethylene tseem muaj cov rwb thaiv tsev zoo thiab qis - kub kuj, tab sis muaj kev tsis zoo rau cov kev laus thermal thiab yog cov nplaim taws.
Txhawm rau txhim kho cov yas ua yeeb yam tau ntxiv rau cov polymer thaum PE Hnab Treading, xws li cov roj av (xws li cov xim (xws li masterbatch). Cov khoom siv no pab tau kho lub cev thiab tshuaj lom neeg ntawm PE hnab kom tau raws li cov kev thov tshwj xeeb.
Thov nco ntsoov tias muaj ntau hom hnab polyethylene, suav nrog lub hnab ntim khoom, ziplock hnab, thiab cov hnab zipper. Thaum cov txheej txheem tsim khoom thiab siv cov hnab ntim cov hnab no yuav txawv, lawv cov khoom siv ua ntej yog polyethylene. Tsis tas li ntawd, vim muaj polyethylene nyuaj rau kev txiav txim siab nyob rau hauv lub ntuj ib puag ncig, siv pE hnab yuav tsum tau ua kom tsis txhob muaj kuab paug ib puag ncig.
