Ihindagurika ry’ibiciro bya peteroli riherutse kwangiza imiterere y’isoko. Ibiciro bya peteroli mpuzamahanga byagabanutse nyuma y’izamuka ry’ibiciro, bituma inkunga y’isoko ry’ibinyabutabire igabanuka. Mu gihe uruhererekane rw’ibicuruzwa bya plastiki n’ibinyabutabire rugabanuka gato, ababikoresha bagaragaza ko badashobora gukoresha ibikoresho fatizo bihenze cyane. Kubera ko bahura n’umuvuduko mwinshi w’ibicuruzwa, PVC ikora nabi uruhererekane rw’inganda muri rusange.
Ibicuruzwa bya PVC bihagaze kuri toni miliyoni 1.374, bizamukaho 0.20% buri kwezi, bizamukaho 70.63% buri mwaka. Nk’uko Longzhong Data ibitangaza, kugeza ku ya 26 Werurwe, iminsi yo kubika ibicuruzwa kuva ku ikorwa ry’inganda za PVC zo mu Bushinwa yagabanutseho 6.67% buri kwezi igera ku minsi 5.6, kuko ibicuruzwa byo mu mahanga bigezwa ku masoko yo mu gihugu no mu mahanga. Imyumvire ku isoko iracyahindagurika, aho abakoresha bahanganye cyane n’ibiciro biri hejuru.
Imihangayiko ya politiki y’ubutaka n’ihindagurika ry’imyumvire y’imari bituma isoko rikomeza guhangana hagati y’ibitekerezo bya politiki y’ubutaka n’inyungu. Nubwo igihe cyo gukenera ibikoresho bya pulasitiki n’imiti cyageze, kudashaka ibikoresho fatizo bihenze bituma imikorere ya PVC igabanuka, bigatuma habaho igitutu gikomeye cyo kugurisha ibicuruzwa ku manywa. Kugabanuka kw’ibicuruzwa biracyatanga inkunga y’igihe gito, nyamara ibiciro biri hejuru byagabanyije cyane intego yo kugura ibicuruzwa, bigabanya icyifuzo kandi bigatera ibitekerezo bibi mu nganda.
Kubera ko nta mwanzuro usobanutse neza ku makimbirane hagati ya Amerika na Irani, ihindagurika ry'isoko ryariyongereye mu gihe hari ibintu bidasanzwe byiyongera. Dufashe Changzhou (Ubushinwa bw'Iburasirazuba) nk'icyitegererezo, igiciro cya PVC SG-5 ikoresha karubone ya karubone (gutoragura ububiko) mu Burasirazuba bw'Ubushinwa cyagabanutseho CNY 50 kuri toni ugereranije n'umunsi wabanje kigera kuri CNY 5.450 kuri toni. Isoko rya PVC rikomeje kuba rito cyane aho ibiciro by'ubucuruzi byagabanutseho gato; igiciro cya PVC SG-5 ikoresha karubone ya karubone (gutoragura ububiko) mu Burasirazuba bw'Ubushinwa kiri hagati ya CNY 4.450 na 4.550 kuri toni, mu gihe ibikorwa bya PVC ikoresha ethylene bifunguye kugira ngo haganirweho. Imyumvire y'isoko ry'igihe gito igabanuka kabiri bitewe no kugabanya amakimbirane yo hanze ya politiki n'ibyitezwe ko isoko rizaba rihagije, aho ishingiro ry'amasezerano ya PVC May mu Burasirazuba bw'Ubushinwa riri hagati ya -50 na -150 CNY kuri toni.
Kubera ko byagizweho ingaruka n’intambara yo mu Burasirazuba bwo Hagati, itangwa ry’ibikoresho fatizo byo gutunganya ibikoresho byo mu bwoko bwa chlor-alkali ku isi ryarushijeho gukomera. Inganda nyinshi zo mu mahanga zikora chlor-alkali zagabanyije umutwaro w’umusaruro, zimwe zigafungwa bitewe n’ibura ry’ibikoresho fatizo. Inganda zikomeye zikora ibikoresho birimo Hanwha, Indoneziya ASC, Tayilande SCG na Formosa Plastics zose zatangaje ko zigiye kugabanya umusaruro cyangwa zigahagarara. Hagati aho, guhagarika ibikorwa bimwe na bimwe byo gutunganya ibikoresho mpuzamahanga no guhagarika inganda zishingiye kuri ethylene byatumye habaho igabanuka rikomeye ry’ibikoresho bya PVC ku isi, ibi bikaba ari icyerekezo cyiza ku bicuruzwa bya PVC byoherezwa mu mahanga n’Ubushinwa.
Ku ruhande rw'imbere mu gihugu, amakimbirane yo mu Burasirazuba bwo Hagati yagabanyije itumizwa rya ethylene, yongera ibyago byo kugabanya umusaruro cyangwa guhagarika inganda za PVC zikomoka muri ethylene mu gihugu, binatuma icyizere cyo kugabanuka kw'ibicuruzwa mu gihugu gitangwa mu buryo bwa ethylene gikomeza kwiyongera. Ibyiringiro byo kugabanuka kw'ibicuruzwa ku isi byatumye ibiciro bya PVC bizamuka cyane. Nubwo Trump yatangaje ko ibiganiro na Irani, impande zombi ziracyatandukanye cyane ku masezerano. Ubucuruzi bwa peteroli bukomeje kwiyongera cyane, kandi imiti ikoreshwa mu ngufu irazamuka cyane. Ariko, PVC ikora nabi izindi miti bitewe n'ibura ry'ibicuruzwa mu gihugu rike ndetse n'izamuka ry'umuvuduko w'imikorere y'inganda za PVC zikomoka kuri karubone.
Nubwo bimeze bityo, ibiciro bya PVC biri hejuru ku rwego mpuzamahanga ndetse n’ubwinshi bw’ibicuruzwa byoherezwa mu mahanga bitanga inkunga ikomeye ku biciro bya PVC byo mu gihugu. Muri rusange, ibiciro bya PVC byitezwe ko bizazamuka ku rwego rwo hejuru mu gihe cya vuba; ariko, kugabanuka kw’ibiciro bya peteroli bishobora gukurura ibiciro bya PVC no gutuma isoko rikomeza kugabanuka.
Chemdo: UwiringirwaUmufatanyabikorwamu ihindagurika ry'isoko rya PVC
Muri iki gihe isoko ririmo kugabanuka kw'ibiciro bya PVC ku isi ndetse n'amahirwe yo kohereza ibicuruzwa mu mahanga, Chemdo ikoresha neza inyungu zayo mu ruhererekane rw'inganda n'umutungo wayo wo mu gihugu kugira ngo ifashe abafatanyabikorwa mpuzamahanga kugumana ibiciro bihamye byo kugura ibicuruzwa, kwemeza ko ibicuruzwa bikomeza kandi bikagira uruhare mu iterambere ry'isoko ryo kohereza ibicuruzwa mu mahanga. Yiyemeje ubufatanye bw'igihe kirekire, Chemdo ni ikiraro cyizewe gihuza inganda za PVC zo mu Bushinwa n'isoko mpuzamahanga, iha abakiriya bo ku isi ubushobozi bwo guhangana n'ihindagurika ry'isoko binyuze mu gutanga serivisi nziza kandi z'umwuga.
