Kusanthula pa Kusintha kwa PE Downstream Consumption Varieties M'tsogolomu.

Pakadali pano, kuchuluka kwa ma polyethylene m'dziko langa ndikwambiri, ndipo kugawa mitundu yakutsika ndizovuta ndipo makamaka kugulitsidwa mwachindunji kwa opanga mapulasitiki. Ndiwogulitsa pang'ono pamakina otsika a ethylene. Kuphatikizidwa ndi kukhudzidwa kwa kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito m'derali, kuchuluka kwa madera ndi kuchuluka kwa kufunikira sikuli bwino.

Ndi kuchulukitsidwa kokhazikika kwa mabizinesi opanga ma polyethylene kumtunda kwa mtsinje m'zaka zaposachedwa, mbali yoperekera yakula kwambiri. Panthawi imodzimodziyo, chifukwa cha kusintha kosalekeza kwa kupanga ndi moyo wa anthu okhalamo, kufunikira kwa iwo kwawonjezeka pang'onopang'ono m'zaka zaposachedwa. Komabe, kuyambira theka lachiwiri la 2021, zochitika zapadziko lonse lapansi zakhala zachinyengo komanso zosinthika. Kufalikira kwa mliriwu ndi nkhondo zapadziko lonse lapansi zapangitsa kuti pakhale kusalinganika kwa dongosolo lazachuma lamphamvu padziko lonse lapansi. kugwa. Kusatsimikizika komwe kukuchulukirachulukira pazachuma chachikulu kwapangitsa kuti anthu azikhala osamala. Pansi pa zomwe zikuchitika masiku ano, zoopsa ndi zovuta zomwe zimakumana ndi chitukuko cha mankhwala a polyethylene ndizovuta kwambiri.

Chiwerengero cha anthu ndi chitukuko cha zachuma chimatsimikizira kugawidwa kwa PE. Malinga ndi madera ogwiritsira ntchito madzi otsika, East China, South China, ndi North China ndi malo omwe amagwiritsidwa ntchito kwambiri kumtunda wa polyethylene m'dziko langa, ndipo adzakhalabe atatu apamwamba pazakudya kwa nthawi yaitali. Komabe, ndi kukhazikitsidwa kosalekeza kwa zida zatsopano zopangira mtsogolomo, zikuyembekezeka kuti kusiyana kwamafuta m'malo atatu akuluakulu ogwiritsira ntchito kuchepetsedwa pang'ono. Zikuyembekezeka kuti izi zikhudza kwambiri tsogolo la kupezeka ndi kufunidwa ndi kayendedwe kazinthu m'magawo akulu. Ndikoyeneranso kutchula kuti ngakhale kuti chiwerengero cha kutsika kwa madzi kumadera akumadzulo ndi chochepa kwambiri kuposa cha East China, South China, ndi North China, choyendetsedwa ndi ndondomeko zapakhomo monga "One Belt, One Road" ndi "Western Development", kutsika kwa madzi a polyethylene kumadera akumadzulo kudzawonjezeka m'tsogolomu. Pali chiyembekezero chowonjezereka, makamaka pazinthu zomwe zimafunidwa ndi zomangamanga motsogozedwa ndi mapaipi, ndipo kufunikira kwa jekeseni ndi zinthu zozungulira zomwe zimadza chifukwa cha kuwongolera kwa moyo ndizodziwikiratu.

Ndiye, ponena za mitundu yodyera kunsi kwa mitsinje m'tsogolomu, ndi ziyembekezo zotani zachitukuko zomwe mitundu yayikulu yakutsika ya polyethylene idzakhala nayo?

Pakali pano, waukulu kumunsi ntchito polyethylene m'dziko langa monga filimu, jekeseni akamaumba, chitoliro, dzenje, waya kujambula, 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.

Kuonjezera apo, mafakitale monga jekeseni, mapaipi, ndi mabowo omwe ali ogwirizana kwambiri ndi kupanga ndi moyo adzakhalabe ogulitsa kwambiri kumunsi kwa polyethylene m'zaka zingapo zikubwerazi, ndipo adzalamulidwabe ndi zomangamanga, zofunikira za tsiku ndi tsiku, ndi boma. zida ndi zida. Moyo wa anthu umagwirizana ndi katundu wokhalitsa, ndipo kufunikira kwa kuwonongeka kwa zinthu kumachepa. Pakalipano, vuto lalikulu lomwe mafakitale omwe ali pamwambawa akukumana nawo ndi chakuti kukula kwa malo ogulitsa 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. Choncho, kusintha kwa nthawi yochepa kumakhala kochepa, ndipo sikukhudzidwa kwambiri ndi zinthu zowonongeka. Makampani a zitoliro amatha kukhudzidwa kwambiri ndi ndondomeko, pamene kuumba jekeseni ndi zinthu zopanda pake zimakhudzidwa kwambiri ndi momwe anthu amagwiritsira ntchito, ndipo kukula kwake kudzachepa m'tsogolomu. kuthekera.

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.
