Nyuma y'Iserukiramuco ry'Impeshyi, igitutu cy'igihombo cya phenol ketone mu nganda cyaragabanutse, ndetse kizana inyungu hagati na mu mpera za Gashyantare. Ariko, muri Werurwe, igiciro cya phenol ketone cyaragabanutse gato, mu gihe ikiguzi cyazamutse, kandi inganda zongeye kugwa mu gihombo. Ku gicamunsi, itangwa rya phenol ketone rirahamye kandi rito, nubwo inganda ziteguye gushyigikira igiciro ari kinini, ariko icyifuzo ntigihagije cyangwa ngo kigabanye izamuka ry'isoko, ikibazo cy'igihombo mu nganda kiragoye guhindura.
Gutangiza igikoresho byageze ku isoko
Umusesenguzi wa Jin Lianchuang, Bian Chenhui, yatangije mbere y'iminsi mikuru y'Iserukiramuco ry'Impeshyi, amasoko yo mu gihugu ya phenol ketone na phenol yari ashyushye, agenda afungwa buhoro buhoro. Nyuma, bitewe n'ingaruka z'ibintu nk'inyongera nke mu masezerano yo gutumiza ibicuruzwa mu mahanga no kwiyongera kw'iperereza ku isoko riturutse ku bashoramari bohereza ibicuruzwa mu mahanga, isoko ryagiye rigaruka buhoro buhoro, maze igiciro cya phenol kiva kuri yuan zirenga 7000 (igiciro cya toni, kimwe kiri hasi) mbere y'Iserukiramuco ry'Impeshyi kigera kuri yuan zirenga 8000, hanyuma kigabanuka kigera kuri yuan 7950. Igiciro cya acetone kiva kuri yuan 5000 cyazamutse kigera kuri yuan 6150.
Mbere, kongera kugurisha imizigo ya phenol mu Bushinwa muri Gashyantare ntibyari bihagije, kandi kongera kugurisha ibicuruzwa byari mu nzu muri Jiangyin byari byinshi cyane, ibyo bikaba byaragize ingaruka nke ku itangwa ry’ibintu ku isoko. Byongeye kandi, ukurikije ibyo kohereza ibicuruzwa mu mahanga byari byitezwe, igitutu cyo kohereza ibicuruzwa mu mahanga ntabwo ari kinini, ibyo bikaba byongera igitekerezo. Ariko, kuvuguruzanya hagati y’ibicuruzwa n’ibikenewe ku isoko ntibyagabanutse neza, kandi iterambere ry’isoko rya phenolic ketone ntabwo rirahagije cyane.
Kugeza ubu, Yangzhou Shiyou yaguraga toni 320.000 ku gikoresho cya phenolone buri mwaka yongeye gusanwa; gutunganya Shenghong byagize ingaruka mbi, kandi igipimo cy'imikorere cyazamuwe hafi 84%. Uko igiciro cya phenolone cyahindukaga ku rwego rwo hejuru, umwanya w'inganda wakomeje kugabanuka, kandi mu mpera za Gashyantare, byahinduye igihombo kikaba inyungu, cyari hafi ya yuan 150. Kuri ubu, kubera ko igiciro cyagabanutse, n'ibikoresho fatizo bikaba biri kwiyongera, igihombo cy'ibicuruzwa bya phenolone ni hafi yuan 300 kuri toni.
Urebye ku isoko, inyungu zazanywe no gushyiraho parikingi no kubungabunga zigenda zishira buhoro buhoro. Igikoresho cya Jiangsu Ruiheng Phenol kigiye kongera gukoreshwa vuba kizagira ingaruka ku isoko. Isoko rya phenolone rishobora gukomeza gukoresha igitutu no guhindura igihombo ingorabahizi.
Igiciro cy'ibikoresho fatizo kiri hejuru
Ukurikije ibikoresho fatizo byo mu rwego rwo hejuru, igiciro cya benzene y’umwimerere cyakomeje kuzamuka. Kuri ubu, igiciro cy’ubucuruzi bw’ibanze ni hagati ya yuan 250-350 ugereranije n’impera za Gashyantare, ibi bikaba ari bimwe mu bintu by’ingenzi biteza igihombo mu nganda za phenolone.
Zhang Wei, umusesenguzi wa Longzhong Information, yavuze ko uku kwiyongera kw'ibicuruzwa biva mu mahanga biterwa ahanini no kugabanuka kw'ibicuruzwa bitumizwa mu mahanga. Ubu ububiko bwa benzene busanzwe bwo ku cyambu cy'Ubushinwa bw'Iburasirazuba buri kuri toni zigera ku 265.000, kugabanuka kwa 1.3% ku kwezi. Vuba aha, igihe cyo kohereza ibicuruzwa muri Hong Kong cyaragabanutse ugereranije n'igihe cya mbere. Byongeye kandi, igiciro cy'ibikoresho by'ingenzi cyarazamuwe, ububiko bwa Shandong buri hasi, kandi bamwe mu bakora mu nganda bagura ibyo bikoresho.
Ukurikije uko isoko ry’isoko rihagaze, peteroli mpuzamahanga iherutse guhindagurika, kandi disiki ya benzene ikomeza gufunga, ariko igiciro cya colomorne kiri hejuru nyuma y’imvura, gishyirwa hejuru y’igiciro cya benzene ya Sinopec.
Nyuma yo kwinjira muri Werurwe, hari ikindi gikoresho cy’ibanze cyavuye mu ishusho ya "V", ariko inkunga y’ibanze yari nto, kandi umwanya wo kuzamuka kw’isoko ntiwari munini. Ibintu bishyigikira kuzamuka kw’isoko ahanini ni uguhagarikwa ku gikoresho cy’umuhondo cya Liaoning. Igikoresho cyo gutwikira propine (PDH) kirimo kugabanuka, kandi ingano y’inyuma ya acryline yaragabanutse. Byongeye kandi, inyungu ya chlorol oxide (PO) yazamutse cyane, bimwe mu bigo bisanzwe bikora chlorol byongereye umutwaro, kandi igikoresho cya Jishen PO nacyo gifite gahunda yo kubyutsa umubiri. Ingaruka rusange z’ibi bintu zongereye ishyaka ryo kugura ibikoresho byihuse.
Jilin, umucuruzi wa peteroli, He Junsong, yavuze ko uko igiciro cya acrylic gikomeza kuzamuka, abakiliya badafite umugambi wo gukomeza kwiruka cyane, kandi ko isoko rihagaze nabi. Ariko, ukurikije igabanuka ry’umutungo winjira muri acrylic ndetse no kubaho kw’ibikenewe bishya, ingaruka zo kugabanuka kwa acrylonitris si nini, kandi isoko ryitezwe ko riziyongera ku rugero ruto.
Ubusabe buke ntacyo bumaze mu kubuteza imbere
Isoko ry’ingenzi rya bisphenol A ryagabanutse cyane. Nyuma yo kugaruka kuva mu mwaka, icyifuzo cya nyuma ntabwo kiri ku rugero rwiza nkuko byari byitezwe. Ihungabana ry’ubukungu, ikoreshwa rya bisphenol A rigenda buhoro buhoro, kandi rigahagarika imyumvire y’inganda.
Wang Chunming, umuyobozi mukuru wa Shandong Ruiyang Chemical Co., Ltd., yavuze ko ubwo igiciro cya bisphenol A cyagabanukaga, hari umubare muto w’abatumije ku isoko bari kubaza, ariko umugambi wo gutanga disiki wari muto, kandi isoko ry’isoko ntiryari rihagije. Igipimo cy’imikorere ya bimwe mu bikoresho bya bisphenol A cyaragabanutse gato, ariko isoko ry’amasoko riracyahagije. Byongeye kandi, igikoresho gishya cya Guangxi Huayi bisphenol A cyashyizwe mu bikorwa neza, ubushobozi bwo gukora imbere mu gihugu buriyongera, ibyo bikarushaho kongera imyumvire yo kwitonda no kwiheba mu nganda.
Ku isoko ry’isoko, icyifuzo cya bisphenol A si kinini, kandi isoko rishingiye ahanini ku kugura ibintu bike bikenewe rimwe gusa. Byongeye kandi, bitewe n’igitutu cy’igihombo, igipimo cy’imikorere ya bisphenol A gishobora kugabanuka cyane. Muri icyo gihe, kugura ibikoresho fatizo biragoye gushyigikira izamuka ry’isoko rya fenolone.
