Kusanthula pa Kusintha kwa kagwiritsidwe ntchito kakutsika kwa PE m'tsogolomu.

Masiku ano, njira zazikulu zogwiritsira ntchitopolyethylenem'dziko langa monga filimu, jekeseni akamaumba, chitoliro, dzenje, kujambula waya, chingwe, metallocene, ❖ kuyanika ndi mitundu ina yaikulu.

Woyamba kupirira, gawo lalikulu kwambiri lazakudya zam'munsi ndi filimu. Kwa makampani opanga mafilimu, chodziwika bwino ndi filimu yaulimi, mafilimu opanga mafilimu ndi filimu yonyamula katundu. Komabe, m’zaka zaposachedwapa, zinthu monga zoletsa matumba apulasitiki ndi kufooketsa mobwerezabwereza kwa chifuno cha mliriwu zawavutitsa mobwerezabwereza, ndipo akukumana ndi mkhalidwe wochititsa manyazi. Kufunika kwazinthu zamakanema apulasitiki otayika kudzasinthidwa pang'onopang'ono ndi kutchuka kwa mapulasitiki owonongeka. Opanga mafilimu ambiri akukumananso ndi luso lazopangapanga zamafakitale, ndipo pang'onopang'ono akupanga mafilimu obwezerezedwanso m'mafakitale okhala ndi mawonekedwe amphamvu komanso magwiridwe antchito. Komabe, chifukwa cha kuwonongeka kwa mafilimu apulasitiki owonongeka, pali zofunikira zamphamvu zonyamula kunja, kapena kufunikira kwa mafilimu opangira kunja omwe amafunika kusungidwa kwa nthawi yaitali kupyola nthawi yowonongeka, komanso mafilimu a mafakitale ndi madera ena akadali osasinthika, kotero zinthu zamakanema zidzagwiritsidwabe ntchito. Idakhalapo ngati chinthu chachikulu kunsi kwa mtsinje wa polyethylene kwa nthawi yayitali, koma pakhoza kukhala kuchepa kwa kukula kwa mowa ndi kuchepa kwa gawo.

Kuphatikiza apo, mafakitale monga jekeseni, mapaipi, ndi maenje omwe ali ogwirizana kwambiri ndi kupanga ndi moyo adzakhalabe ogulitsa kwambiri kunsi kwa polyethylene m'zaka zingapo zikubwerazi, ndipo adzalamulidwabe ndi zomangamanga, zofunikira za tsiku ndi tsiku, ndi zida za boma. ndi zida. Moyo wa anthu umagwirizana ndi katundu wokhalitsa, ndipo kufunikira kwa kuwonongeka kwa zinthu kumachepa. Vuto lalikulu lomwe mafakitale omwe ali pamwambawa akukumana nawo pakali pano ndikuti kukula kwa gawo logulitsa nyumba kwatsika m'zaka zaposachedwa. Chifukwa cha zinthu monga malingaliro oyipa pamalingaliro omwe anthu amadya chifukwa cha miliri yobwerezabwereza, chitukuko cha makampani opanga zinthu chikuyang'anizana ndi kukula kwina. Chifukwa chake, kusintha kwakanthawi kochepa kumakhala kochepa, kosakhudzidwa kwambiri ndi zinthu zowonongeka, makampani a chitoliro amatha kukhudzidwa kwambiri ndi ndondomeko, pamene jekeseni wopangira jekeseni ndi zinthu zopanda kanthu zimakhudzidwa kwambiri ndi malingaliro a anthu okhalamo, komanso kukula kwake. adzakhala pang'onopang'ono kwa kanthawi zotheka m'tsogolo.

Ndi chitukuko mosalekeza cha sayansi ndi luso, ndi munthu payekha ndi humanization luso la mankhwala pulasitiki, komanso mankhwala khalidwe luso ndi makonda kupanga zofunikira komanso mosalekeza kukhala. Chifukwa chake, m'tsogolomu, makampani opanga pulasitiki aziwonjezera kufunika kwa zida zina zomwe zimathandizira kukonza magwiridwe antchito apulasitiki, monga metallocenes, mapulasitiki opukutira, zida zokutira ndi zinthu zina zamtengo wapatali kapena zinthu zomwe zili ndi zofunikira zapadera m'magawo apadera. . Komanso, chifukwa anaikirapo kupanga mabizinesi kumtunda polyethylene kupanga m'zaka zaposachedwapa, chifukwa kwambiri mankhwala inversion, ndi mkangano pakati pa Russia ndi Ukraine m'chaka anachititsa mkulu mitengo mafuta kukankhira mmwamba phindu kunsi mtsinje wa ethylene, ndi kukwera mtengo. ndi kupereka zinachititsa kwambiri mankhwala homogeneity. Pansi pa zomwe zikuchitika panopa, Opanga polyethylene akuyamba kugwira ntchito kwambiri popanga zinthu zamtengo wapatali monga metallocenes, zojambulajambula, ndi zokutira, mogwirizana ndi chitukuko cha mafakitale akumunsi. Chifukwa chake, kuchuluka kwa zinthu zomwe zikuchulukirachulukira kungachuluke kwambiri m'tsogolomu.

Kuonjezera apo, pamene mliriwu ukupitirira mobwerezabwereza, komanso kafukufuku ndi chitukuko cha zopangidwa zatsopano ndi opanga, ulusi wa polyethylene, mankhwala ndi zodzitetezera zipangizo zapadera zimatsatiridwanso pang'onopang'ono ndikupangidwa, ndipo zofuna zamtsogolo zidzawonjezekanso pang'onopang'ono.
