Ubwiyongere bugaragara bw'umusaruro w'amashanyarazi menshi mu gihugu no kugabanuka kw'itandukaniro ry'ibiciro ku murongo

Kuva mu 2020, inganda za polyethylene zo mu ngo zinjiye mu cyiciro rusange cy’ikwirakwizwa ry’ibikoresho, kandi ubushobozi bw’umusaruro w’ibikoresho byo mu ngo buri mwaka bwariyongereye cyane, aho impuzandengo y’izamuka ry’ibipimo birenga 10%. Umusaruro wa polyethylene ikorerwa mu ngo wiyongera cyane, hamwe n’ihinduka rikomeye ry’ibicuruzwa ndetse n’irushanwa rikomeye ku isoko rya polyethylene. Nubwo icyifuzo cya polyethylene nacyo cyagaragaje icyerekezo cy’izamuka ry’ibikenewe mu myaka ya vuba aha, izamuka ry’ibikenewe ntiryihutishije nk’izamuka ry’ibicuruzwa. Kuva mu 2017 kugeza mu 2020, ubushobozi bushya bwo gukora polyethylene yo mu ngo bwibanze cyane ku bwoko bufite voltage nke n’umurongo ugororotse, kandi nta bikoresho bifite voltage nyinshi byashyizwe mu bikorwa mu Bushinwa, bituma habaho umusaruro ukomeye ku isoko rifite voltage nyinshi. Mu 2020, uko itandukaniro ry’ibiciro hagati ya LDPE na LLDPE ryagendaga ryiyongera buhoro buhoro, kwitabwaho kw’ibicuruzwa bya LDPE byariyongereye. Ishami rikora EVA hamwe n’ishami rya Zhejiang Petrochemical LDPE byatangiye gukora mu 2022, bifite ubushobozi bwo gukora toni miliyoni 3.335 z’umuvuduko mwinshi mu ngo kuva ku munsi ushize.

Mu 2023, isoko ry’umuvuduko mwinshi ryagaragaje impinduka zigenda zigabanuka. Dufashe urugero ku isoko ry’Amajyaruguru y’Ubushinwa, igiciro cy’umuvuduko mwinshi kuva muri Mutarama kugeza muri Gicurasi cyari 8853 yuan/toni, igabanuka rikomeye ry’umwaka ku mwaka rya 24.24%. Mu gihembwe cya mbere cy’ubwinshi bw’ibicuruzwa bya pulasitiki byari bikomeye cyane. Igiciro cy’umuvuduko wo kuva muri Mutarama kugeza muri Mata cyari 8273, igabanuka ry’umwaka ku mwaka rya 7.42%. Itandukaniro ry’ibiciro hagati y’amashanyarazi menshi n’amashanyarazi ryagabanutse cyane. Ku ya 23 Gicurasi, amashanyarazi yo mu gihugu ku isoko ry’Amajyaruguru y’Ubushinwa yari 7700-7950 yuan/toni, mu gihe amashanyarazi yo mu gihugu ku isoko yari 8000-8200 yuan/toni. Itandukaniro ry’ibiciro hagati y’amashanyarazi menshi n’amashanyarazi ryari 250-300 yuan/toni.

Muri rusange, bitewe n’uko ubushobozi bwo gukora polyethylene mu ngo bukomeje kwiyongera ndetse n’ubwiyongere bw’ibicuruzwa bitangwa mu ngo, ikibazo cy’ubwiyongere bw’ibicuruzwa mu nganda za polyethylene cyariyongereye. Nubwo ikiguzi cyo gukora voltage nyinshi kiri hejuru gato ugereranyije n’iya linear, bitewe n’uko linear na metallocene zisimburana mu bice bimwe na bimwe by’umusaruro, biragoye gushyigikira ibiciro biri hejuru n’inyungu nyinshi ku isoko rya polyethylene ridafite imbaraga, kandi itandukaniro ry’ibiciro hagati y’amashanyarazi menshi n’aya linear ryagabanutse cyane.
