Polyethylene (PE) yog cov thermoplastic resin ua los ntawm polymerization ntawm ethylene.Kev lag luam, nws kuj suav nrog ethylene thiab ib qho me me ntawm α- Copolymers ntawm olefins.Polyethylene tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab zoo li siv quav ciab.Nws muaj qhov ua haujlwm tsis zoo ntawm qhov kub thiab txias (qhov tsawg kawg nkaus kev pabcuam kub tuaj yeem ncav cuag - 100 ~ - 70 ° C), tshuaj lom neeg ruaj khov, thiab tuaj yeem tiv taus cov kua qaub thiab alkali feem ntau (tsis tiv taus acids nrog oxidizing zog).Nws yog insoluble nyob rau hauv cov kuab tshuaj nyob rau hauv ib txwm kub, nrog me me nqus dej thiab zoo heev hluav taws xob rwb thaiv tsev.
Kev siv tus nqi ntawm polyethylene ntau lawm muaj peev xwm nyob rau hauv Tuam Tshoj yog siab, thiab nws yog khaws cia ntawm li 90% tag nrho cov xyoo puag ncig.Nrog rau txoj kev loj hlob ntawm Tuam Tshoj txoj kev lag luam, qhov kev thov ntawm polyethylene kev ua lag luam nce sai, thiab cov zis kuj nce ntxiv.Nyob rau hauv xyoo tas los no, Tuam Tshoj cov khoom siv polyethylene muaj peev xwm thiab cov khoom tsim tawm tau tuav ib qho kev nce ntxiv.Tuam Tshoj tus polyethylene ntau lawm yog kwv yees li 22.72 lab tons, nrog rau ib xyoo ntawm lub xyoo nce ntawm 11.8%, thiab cov zis yuav ntau tshaj 30 lab tons.
Qhov pom meej noj ntawm polyethylene maj mam nce.Hauv xyoo 2021, qhov pom tseeb ntawm kev siv polyethylene hauv Suav teb tau txo mus rau 37.365 lab tons, ib xyoos ib zaug poob ntawm 3.2%.Nws feem ntau yog vim muaj kev cuam tshuam ntawm qhov xwm txheej thiab kev tswj hwm kev siv hluav taws xob, thiab qee qhov chaw ua haujlwm qis qis tau tshem tawm lossis txo cov khoom lag luam.Nrog rau kev txhim kho ntawm tus kheej txaus, PE ntshuam dependence yuav maj mam txo.Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhim kho ntawm cov xwm txheej sib kis thiab kev loj hlob tsis tu ncua ntawm kev lag luam hauv tsev, PE kev thov yuav nce ntxiv.Nws cia siab tias yuav maj mam rov qab los hauv 2022, nce mus rau 39 lab tons.
Khoom: saj tsis qab, tsis muaj ntxhiab, tsis muaj tshuaj lom, opalescent, waxy hais nrog qhov ntom ntawm li 0.920 g / cm3 thiab melting point ntawm 130 ℃ ~ 145 ℃.Insoluble nyob rau hauv dej, me ntsis soluble nyob rau hauv hydrocarbons, thiab lwm yam. Nws muaj peev xwm tiv taus corrosion ntawm feem ntau acids thiab alkalis, muaj dej nqus dej tsawg, tseem tuaj yeem tswj tau yooj yim ntawm qhov kub thiab txias, thiab muaj hluav taws xob rwb thaiv tsev siab.
