Guhanura no gusesengura umusaruro wa polietilen mu Bushinwa no gukoresha ibicuruzwa bigaragara mu 2022

Polyethylene (PE) ni resinoplastique ikozwe na polymerisation ya Ethylene.Mu nganda, ikubiyemo na Ethylene hamwe na α- Copolymers ya olefins.Polyethylene nta mpumuro nziza, idafite uburozi, kandi yumva ari ibishashara.Ifite ubushyuhe buke cyane (ubushyuhe bwa serivisi ntarengwa bushobora kugera - 100 ~ - 70 ° C), imiti ihamye, kandi irashobora kurwanya aside nyinshi na alkali (ntabwo irwanya aside ifite imiterere ya okiside).Ntishobora gukemuka muri rusange kumashanyarazi mubushyuhe busanzwe, hamwe no kwinjiza amazi make hamwe no gukwirakwiza amashanyarazi meza.

Ikoreshwa ry’ubushobozi bwa polyethylene mu Bushinwa ni ryinshi, kandi rikomezwa hafi 90% umwaka wose.Iterambere ry’ubukungu bw’Ubushinwa, isoko rya polyethylene ryiyongera vuba, kandi umusaruro nawo uriyongera.Mu myaka yashize, ubushobozi bw’umusaruro wa polietilen mu Bushinwa n’ibisohoka byakomeje kwiyongera.Umusaruro wa polyethylene mu Bushinwa ugera kuri toni miliyoni 22.72, aho umwaka ushize wiyongereyeho 11.8%, kandi umusaruro uzarenga toni miliyoni 30.

Ibiryo bigaragara bya polyethylene byiyongereye buhoro buhoro.Mu 2021, bigaragara ko ikoreshwa rya polyethylene mu Bushinwa ryaragabanutse kugera kuri toni miliyoni 37.365, umwaka ushize wagabanutseho 3,2%.Biterwa ahanini ningaruka ziterwa nicyorezo no kugenzura ikoreshwa ryingufu, kandi inganda zimwe na zimwe zo hepfo zihagarika cyangwa zigabanya umusaruro.Hamwe nogutezimbere kwihaza, PE kwishingira ibicuruzwa bizagenda bigabanuka buhoro buhoro.Mu bihe biri imbere, hamwe n’iterambere ry’icyorezo n’iterambere ry’ubukungu bw’imbere mu gihugu, icyifuzo cya PE kizakomeza kwiyongera.Biteganijwe ko izakira buhoro buhoro mu 2022, ikiyongera ikagera kuri toni miliyoni 39.

Ibyiza: uburyohe, butagira impumuro nziza, idafite uburozi, opalescent, ibishashara bifite ubucucike bwa 0,920 g / cm3 hamwe no gushonga kwa 130 ℃ ~ 145 ℃.Kudashonga mumazi, gushonga gake muri hydrocarbone, nibindi. Irashobora kurwanya kwangirika kwa acide na alkalis nyinshi, ifite amazi make, irashobora gukomeza guhinduka mubushyuhe buke, kandi ifite amashanyarazi menshi.
