Iriburiro: Mu myaka itanu ishize, Ubushinwa bwa polipropilene itumizwa mu mahanga n’ibicuruzwa byoherezwa mu mahanga, nubwo buri mwaka ibicuruzwa biva mu mahanga bya polipropilene by’Ubushinwa bigenda bigabanuka, ariko biragoye kugera ku kwihaza mu gihe gito, kwishingira ibicuruzwa biva hanze biracyahari.Ku bijyanye no kohereza ibicuruzwa hanze, hashingiwe ku idirishya ryoherezwa mu mahanga ryafunguwe mu myaka 21, ubwinshi bwoherezwa mu mahanga bwiyongereye cyane, kandi ibicuruzwa byoherezwa mu mahanga n’ibicuruzwa byateye imbere ku buryo bugaragara.

I. Ibihe byinjira no kohereza hanze polypropilene mubushinwa

Ibitumizwa mu mahanga: Kuva muri 2018 kugeza 2020, ibicuruzwa biva mu mahanga bya polypropilene mu Bushinwa byakomeje kwiyongera.Nubwo umusaruro w’imiti y’amakara warekuwe hakiri kare kandi igipimo cyo kwihaza ku bicuruzwa byo mu gihugu ndetse n’ibicuruzwa byo mu rwego rwo hejuru byariyongereye cyane, kubera inzitizi za tekiniki, Ubushinwa bwinjira mu mahanga bwa polipropilene yo mu rwego rwo hejuru bwari bukiriho.Mu 2021, imbeho ikonje muri Amerika yatumye hafungwa ibice bya polyolefine muri Amerika, kandi ibura rya polipropilene mu mahanga ryazamuye igiciro cy’isoko.Ibikoresho byatumijwe mu mahanga ntabwo byari bifite inyungu zibiciro.Byongeye kandi, Shanghai Petrochemical, Zhenhai Petrochemical, Yanshan Petrochemical hamwe nandi masosiyete yo mu gihugu yateye intambwe mu bikoresho biboneye, ibikoresho bifuro ifuro n’ibikoresho by’imiyoboro binyuze mu bushakashatsi bwakomeje, kandi igice cya polipropilene yatumijwe mu mahanga cyarasimbuwe.Ibicuruzwa byatumijwe mu mahanga byagabanutse, ariko muri rusange, inzitizi za tekinike ziracyahari, polipropilene yo mu rwego rwo hejuru itumizwa mu mahanga.

Ibyoherezwa mu mahanga: Kuva mu 2018 kugeza 2020, Ubushinwa buri mwaka bwohereza ibicuruzwa hanze ya polipropilene ni toni 400.000, bifite ishingiro rito.Ubushinwa bwatangiye bitinze mu nganda za polypropilene, kandi ibicuruzwa byayo ni ibikoresho rusange, ntabwo rero bifite inyungu zo kohereza mu mahanga mu bijyanye n’ibipimo bya tekiniki.Ariko, guhera mu 2021, ibirori bya "Swan birabura" muri Amerika byazanye amahirwe menshi yo kohereza ibicuruzwa mu mahanga n'abacuruzi bo mu gihugu, aho ibyoherezwa mu mahanga byazamutse bigera kuri toni miliyoni 1.39.Nyamara, kubera ko hari inganda zitunganya amakara mu gihugu, igiciro kiratandukanye, kandi ingaruka z’ibiciro bya peteroli ziragabanuka.Mu gice cya mbere cya 2022, iyo igiciro cya peteroli kizamutse, polypropilene yo mu Bushinwa ifite ibyiza byinshi byibiciro.Nubwo ibicuruzwa byoherezwa mu mahanga bitarenze ibyo mu 2021, biracyari byinshi.Muri rusange, Ubushinwa bwohereza ibicuruzwa bya polypropilene bushingiye ahanini ku nyungu z’ibiciro, kandi ahanini ni ibikoresho rusange.

2.Benshi mu byiciro bitumizwa mu mahanga n'inkomoko ya polypropilene mu Bushinwa.

Polypropilene yo mu Bushinwa iracyafite ibicuruzwa bimwe na bimwe bidashobora guhaza isoko, cyane cyane mu bicuruzwa byo mu rwego rwo hejuru, ibikoresho fatizo bishingiye cyane cyane ku bicuruzwa bitumizwa mu mahanga, urugero nko guterwa inshinge nyinshi, ibicuruzwa biva mu mahanga ndetse n’ibicuruzwa byinshi (nko gukora imodoka), fibre fusion (kurinda ubuvuzi) nizindi nganda ziyongera, kandi ibipimo fatizo biri hejuru, gutumizwa mu mahanga bikomeje kuba byinshi.

Urugero, mu 2022, ibihugu bitatu bya mbere mu bijyanye n’ibitumizwa mu mahanga ni: Koreya ya mbere, Singapore ya kabiri, 14.58%, Leta zunze ubumwe z’Abarabu, 12.81%, na Tayiwani ya kane, 11.97%.

3.Iterambere ryubushinwa polypropilene mubibazo

Iterambere ry’inganda za polypropilene mu Bushinwa riracyari mu mutego munini ariko udakomeye, cyane cyane kubura ibicuruzwa byapiganwa ku isi, gushingira ku gutumiza mu mahanga ibikoresho bya polipropilene yo mu rwego rwo hejuru biracyari hejuru, kandi ibicuruzwa biva mu mahanga mu gihe gito bikomeje kugumana bimwe. igipimo.Kubera iyo mpamvu, polypropilene yo mu Bushinwa ikeneye kongera iterambere n’umusaruro w’ibicuruzwa byo mu rwego rwo hejuru, no kwerekana ibicuruzwa byapiganwa ku isi hose, bigatwara umugabane utumizwa mu mahanga icyarimwe, bikomeza kwagura ibyoherezwa mu mahanga bya polipropilene birashobora gukemura mu buryo butaziguye kandi neza igitutu cy’ibicuruzwa.
