Kusanthula pa Kusintha kwa kugwiritsidwa ntchito kwa PE mtsogolo.

Pakadali pano, kugwiritsa ntchito kwakukulu kwapolyethyleneM'dziko langa muli filimu, jekeseni, chitoliro, dzenje, waya wojambulidwa, chingwe, metallocene, zokutira ndi mitundu ina yayikulu.

Choyamba kunyamula katundu wolemera kwambiri, gawo lalikulu la ndalama zomwe zimagwiritsidwa ntchito pansi pa mtsinje ndi mafilimu. Kwa makampani opanga mafilimu, makampani opanga mafilimu ndi mafilimu opaka zinthu. Komabe, m'zaka zaposachedwa, zinthu monga zoletsa matumba apulasitiki ndi kufooka mobwerezabwereza kwa kufunikira chifukwa cha mliriwu zawavutitsa mobwerezabwereza, ndipo akukumana ndi vuto lochititsa manyazi. Kufunika kwa zinthu zapulasitiki zachikhalidwe zomwe zimagwiritsidwa ntchito nthawi zina kudzasinthidwa pang'onopang'ono ndi kufalikira kwa mapulasitiki owonongeka. Opanga mafilimu ambiri akukumananso ndi zatsopano zaukadaulo wamafakitale, ndipo pang'onopang'ono akupita patsogolo kuti apange mafilimu obwezeretsanso mafakitale okhala ndi khalidwe labwino komanso magwiridwe antchito. Komabe, chifukwa cha kuwonongeka kwa mafilimu apulasitiki owonongeka, pali zofunikira kwambiri pakuyika zinthu zakunja, kapena kufunikira kwa mafilimu opaka zinthu akunja omwe amafunika kusungidwa kwa nthawi yayitali kupitirira nthawi yowonongeka, ndipo mafilimu amakampani ndi madera ena akadali osasinthika, kotero zinthu zamafilimu zidzagwiritsidwabe ntchito. Zakhalapo ngati chinthu chachikulu pansi pa polyethylene kwa nthawi yayitali, koma pakhoza kukhala kuchepa kwa kukula kwa kugwiritsidwa ntchito komanso kuchepa kwa chiwerengerocho.

Kuphatikiza apo, mafakitale monga kupanga jakisoni, mapaipi, ndi mabowo omwe amagwirizana kwambiri ndi kupanga ndi moyo adzakhalabe zinthu zazikulu zomwe anthu amagwiritsa ntchito pansi pa polyethylene m'zaka zingapo zikubwerazi, ndipo adzayang'aniridwabe ndi zomangamanga, zofunikira za tsiku ndi tsiku, ndi zida zapakhomo ndi zida. Moyo wa anthu umalumikizidwa ndi katundu wolimba, ndipo kufunikira kwa kuwonongeka kwa zinthu kwachepa. Vuto lalikulu lomwe mafakitale omwe ali pamwambapa akukumana nalo pakadali pano ndikuti kuchuluka kwa kukula kwa gawo la malo ogulitsa nyumba kwayima m'zaka zaposachedwa. Chifukwa cha zinthu monga ndemanga zoyipa pa momwe anthu amagwiritsira ntchito zinthu zomwe zabwera chifukwa cha miliri yobwerezabwereza, chitukuko cha makampani opanga zinthu chikukumana ndi kukana kukula. Chifukwa chake, kusintha kwa gawo lakanthawi kochepa kuli kochepa, komwe sikukhudzidwa kwambiri ndi zinthu zomwe zimawonongeka, makampani opanga mapaipi ali ndi mwayi wokhudzidwa kwambiri ndi mfundo, pomwe kupanga jakisoni ndi zinthu zopanda kanthu zimakhudzidwa kwambiri ndi momwe anthu amagwiritsira ntchito zinthu, ndipo kuchuluka kwa kukula kudzachepa kwa nthawi yayitali mtsogolo.

Ndi chitukuko chopitilira cha sayansi ndi ukadaulo, kusintha kwa zinthu zapulasitiki payekhapayekha komanso kukhala zaumunthu, komanso luso la zinthu komanso zofunikira pakupanga zinthu zomwe zasinthidwa zikukula nthawi zonse. Chifukwa chake, mtsogolo, makampani opanga zinthu zapulasitiki adzawonjezera kufunikira kwa zinthu zina zopangira zomwe zimathandizira magwiridwe antchito a zinthu zapulasitiki, monga metallocenes, mapulasitiki ozungulira, zinthu zokutira ndi zinthu zina zamtengo wapatali kapena zinthu zomwe zili ndi zofunikira zapadera m'magawo apadera. Kuphatikiza apo, chifukwa cha kupanga kwakukulu kwa makampani opanga polyethylene m'zaka zaposachedwa, zomwe zidapangitsa kuti zinthu zisinthe kwambiri, komanso mkangano pakati pa Russia ndi Ukraine m'chakachi udapangitsa kuti mitengo yamafuta ikhale yokwera kwambiri kuti phindu la ethylene likwere, ndipo kukwera kwa mtengo ndi kupezeka kwa zinthu kudapangitsa kuti zinthu zigwirizane kwambiri. Pansi pa zomwe zikuchitika pano, opanga polyethylene akuyamba kugwira ntchito kwambiri popanga zinthu zamtengo wapatali monga metallocenes, rotational molding, ndi zokutira, mogwirizana ndi chitukuko cha mafakitale otsika. Chifukwa chake, kuchuluka kwa zinthu kumatha kukwera mpaka pamlingo winawake mtsogolo.

Kuphatikiza apo, pamene mliriwu ukupitirira mobwerezabwereza, komanso kafukufuku ndi chitukuko cha mitundu yatsopano ndi opanga, ulusi wa polyethylene, zipangizo zapadera zamankhwala ndi zoteteza zimatsatiridwa pang'onopang'ono ndikupangidwa, ndipo kufunikira kwamtsogolo kudzawonjezekanso pang'onopang'ono.
