Polypropilene yo mu rwego rwo hejuru yerekeza ku bicuruzwa bya polypropilene hiyongereyeho ibikoresho rusange (gushushanya, gushonga kwa cololymerisation nkeya, gushushanya inshinge za homopolymer, fibre, nibindi), harimo ariko ntibigarukira gusa kubikoresho bibonerana, CPP, ibikoresho bya tube, ibicuruzwa bitatu byo hejuru.

Mu myaka yashize, polypropilene yo mu rwego rwo hejuru yahindutse intambara, ubushobozi bwa PP yo mu rwego rwo hejuru ikomeje kwiyongera, ifuro rya polypropilene, metallocene polypropilene, polypropilene eshatu zo hejuru, ivu rya polipropilene nini cyane n’ubundi bwoko bushya bw’imigabane ku isoko ni rito, ariko umwanya ukenewe ni mugari, ahazaza h'iterambere ry'isoko ni rinini;Kugeza mu 2021, umusaruro wa polipropilene wo mu rwego rwo hejuru wageze kuri toni 7,963.400, ibicuruzwa byatumijwe mu mahanga byari toni 2,399.100, naho ibicuruzwa biva mu mahanga bigera kuri 23.57%.Ibicuruzwa bimwe na bimwe byugarije abanyamahanga kwiharira kandi bigenda muburyo bwo gutangira guhera.Igihe cya 2021-2025 nicyiciro cyiterambere cyiterambere rya polipropile yo mu rwego rwo hejuru, kandi umuvuduko wubwiyongere uzagabanuka muri 2025-2030.

Mu gihe cya 2022-2030, hateganijwe ko toni miliyoni 35.63 / umwaka zishyirwaho za polipropilene zishyirwa mu bikorwa by’ubucuruzi mu Bushinwa, ariko polypropilene yo mu rwego rwo hejuru ihwanye na 30% gusa yo kwagura ubushobozi bwa polypropilene, bityo ikaba igera kuri miliyoni 10.7 toni.Usibye igice cyibikorwa bya PDH yumushinga, kubera ko isoko yubusa ya Ethylene ishobora kubyara polymer imwe gusa, ntabwo izashyirwa mubice bya polipropile yo mu rwego rwo hejuru mugihe gito, nigice cyamakara atunganya imiti nibindi bikoresho, kubera ko uburyo bushya bwibikoresho budahungabana, ikoranabuhanga ntirikuze nizindi mpamvu zituma inganda zitunganya inganda n’amakara zitera imbere mu buryo buhamye, bityo ibikoresho rusange nko gushushanya insinga zashushe hasi ya cololymerisation byibasiye isoko, ntabwo byashyizwe mubikorwa nka polipropile yo mu rwego rwo hejuru. kugeza ubu;Mu bihe biri imbere, Sinopec na CNPC bizagura ubushobozi bitewe n'amateka yabo meza kandi inzira ihamye.Imiterere yabo yibanda ku isoko ryohejuru rikenewe ku isoko.Mu bihe biri imbere, amarushanwa ya polipropilene yo mu rwego rwo hejuru azakomeza kuzenguruka amavuta yombi.

Kubijyanye nibisabwa, polypropilene yo mu rwego rwo hejuru irakenewe cyane mu guhindura imodoka.Iterambere ryihuse ryibitekerezo byoroheje byimodoka hamwe nibinyabiziga bishya bitanga ingufu byahaye imbaraga isoko ryo guhindura ibinyabiziga.Ingingo nyamukuru yo gukura ikenewe ni hagati-yo hagati ya fusion copolymerisation.Iya kabiri ni urukuta ruto.Gupakira ibintu byinjijwe mumico.Inganda zitwara abantu zateye imbere byihuse hifashishijwe ibikorwa byubuzima rusange.Iterambere ryubwiyongere rirenze kure umuvuduko rusange wubwiyongere bwa polypropilene.Inganda ziboneye zikoreshwa cyane kandi zifite ibyiringiro byinshi.Ikoreshwa cyane cyane mumifuka yo gushiramo imiti, ibikoresho byubuvuzi, gupakira ibikoresho, ibicuruzwa byabana, nibindi. Muri byo, ubuvuzi buboneye bwubuvuzi bugera kuri 40% byamafaranga yose abonerana, agakurikirwa no gupakira ibintu.Bitewe no gusaza mu Bushinwa hamwe n’ibihe by’icyorezo gisanzwe, ibyuma bibonerana bigomba gutera imbere, kandi isoko ry’imbere mu gihugu rishingiye cyane cyane ku bicuruzwa bitumizwa mu mahanga, bityo haracyari umwanya munini wo guteza imbere isoko ry’imbere mu gihe kiri imbere.Hanyuma, ibikoresho byo murwego rwohejuru nka binary na ternary copolymerisation ya CPP hamwe numuyoboro wamazi ashyushye bigarukira kumasoko bitewe nubushobozi buke bwisoko nibikorwa bike.Isoko ryimbere mu gihugu rishobora gusa kugera kuri 50% byimigabane yisoko, kandi haracyari umwanya munini wo gukinira isoko ryimbere mu gihugu.Muri make, umuvuduko witerambere wigihe kizaza cyo kwagura ubushobozi bwa polypropilene murwego rwohejuru ntago ari munsi yumuvuduko rusange wamasoko ya polypropilene, kandi isoko ryisoko riracyafite umwanya munini witerambere, imiterere yigihe kizaza yubushakashatsi bwa polipropilene yo murwego rwohejuru nibikorwa byiterambere ni ni ngombwa.
