Icyumweru gishize, isoko rya epoxy resin yari ifite intege nke, kandi ibiciro byinganda byagabanutse ubudasiba, ubusanzwe byari byiza. Mu cyumweru, ibikoresho fatizo bisphenol A yakoraga ku rwego rwo hasi, naho ibindi bikoresho fatizo, epichlorohydrin, byahindutse bikamanuka mu ntera nto. Igiciro rusange cyibikoresho byagabanije inkunga yacyo kubicuruzwa. Ibikoresho bibiri bibisi byakomeje kugabanuka muburyo budakomeye, kandi isoko rya resin ntabwo ryateye imbere. Impamvu nyinshi mbi zateye kutabasha kubona impamvu nziza yigiciro cya epoxy resin. Amagambo yerekana ibirango bya kabiri nicyiciro cya gatatu LER kumasoko yatanzwe kuri 15800 yuan / toni. Ibiciro byinganda zikomeye zikora ibicuruzwa byagabanutse kurwego rwo hasi muri uyumwaka, kandi haracyariho igabanuka ryibiciro.
Icyumweru gishize, uruganda runini muri Jiangsu rwahagaritse kubungabunga, kandi umutwaro wibindi bimera wahindutse gake. Muri rusange umutwaro wo gutangira wagabanutse ugereranije nicyumweru gishize. Mugihe cyicyumweru, icyifuzo cyo hasi cyari gito, kandi ikirere cyibicuruzwa bishya cyari cyoroshye. Gusa ku wa gatatu ushize, umwuka wiperereza no kuzuza warahindutse gato, ariko wari wiganjemo kuzuzwa gusa. Umuvuduko ku bakora inganda zohereza ibicuruzwa ni mwinshi, kandi inganda zimwe zumvise ko ibarura riri hejuru gato. Hariho intera nini mubitangwa, kandi intego yo gucuruza isoko iri hasi.
Bisphenol A: Mu cyumweru gishize, igipimo cyo gukoresha ubushobozi bwa bispenol yo mu gihugu A cyari 62.27%, cyamanutseho amanota 6.57 ku ijana guhera ku ya 3 Ugushyingo. Muri iki cyumweru cyo guhagarika no gufata neza amashanyarazi muri Aziya yepfo muri iki cyumweru, uruganda rwa Nantong Star Bisphenol Uruganda ruteganijwe gufungwa kugira ngo rushobore kumara icyumweru kimwe ku ya 7 Ugushyingo, biteganijwe ko ruzahagarikwa ku murongo wa mbere ku ya 6 Ugushyingo. icyumweru). Huizhou Zhongxin yafunzwe by'agateganyo iminsi 3-4, kandi nta guhindagurika kugaragara mumitwaro yizindi nzego. Kubwibyo, igipimo cyo gukoresha ubushobozi bwa bispenol yo murugo Igihingwa kigabanuka.
Epichlorohydrin: Mu cyumweru gishize, igipimo cyo gukoresha ubushobozi bw’inganda zo mu gihugu cya epichlorohydrin cyari 61.58%, cyiyongereyeho 1.98%. Mu cyumweru, Dongying Liancheng 30000 t / uruganda rwa propylene rwahagaritswe ku ya 26 Ukwakira. Kugeza ubu, chloropropene nicyo gicuruzwa nyamukuru, kandi epichlorohydrin ntabwo yongeye gutangira, kandi iri mu nzira yo kubikurikirana; Umusaruro wa buri munsi wa epichlorohydrin ya Binhua Group wiyongereye kugera kuri toni 125 kugirango uhuze hydrogène hydrogène yo hejuru; Ningbo Zhenyang 40000 t / uruganda rutunganya glycerol rwongeye gutangira ku ya 2 Ugushyingo, kandi umusaruro wa buri munsi ni toni 100; Dongying Hebang, Hebei Jiaao na Hebei Zhuotai baracyari muri parikingi, kandi igihe cyo gutangira kirakurikirana; Imikorere yizindi nganda ifite impinduka nke.
Iteganyagihe ry'isoko
Bisphenol Igicuruzwa cyisoko cyazamutseho gato muri wikendi, kandi inganda zo hepfo zagize amakenga mukwinjira kumasoko. Abasesenguzi b'isoko bemeza ko: imitekerereze y'abaguzi n'abagurisha bazakomeza gukina imikino mu cyumweru gitaha, hamwe n'impinduka nke mu gihe gito. Ibiteganijwe bidakomeye bizanwa nigikoresho gishya bizahagarika imitekerereze yisoko, kandi isoko riteganijwe guhinduka hafi yumurongo wibiciro.
Chloride ya cycle yakomeje kugenda ishyamba. Umubare munini w’ibarura rusange hamwe n’ibihuha bivuga ko amajyaruguru abiri y’amajyaruguru azashyirwa mu bikorwa mu kwezi gutaha byatumye abantu ku isoko bagira amakenga kandi umwuka wo gutegereza no kubona ku isoko ntiwahindutse. Dukurikije isesengura ry’imbere, nubwo isoko iriho ihagaze by'agateganyo, birashoboka cyane ko isoko ry'ejo hazaza rizakomeza kugabanuka.
Isoko rya LER ntabwo rifite gusa umusaruro wiyongera wibikoresho byo kubungabunga, ahubwo rifite n'imbaraga nshya zinjira ku isoko. Byumvikane ko igihingwa cya epoxy i Wuzhong, Zhejiang (Uruganda rwa Shanghai Yuanbang No.2) cyashyizwe mu igeragezwa mu minsi yashize. Nyuma yicyiciro cya kabiri, ibara ryibicuruzwa bigeze kuri 15 #. Nibikomeza kuguma bihamye mugihe kizaza, ibicuruzwa ntabwo bizinjira kumasoko igihe kirekire. LER izakomeza guhamagarwa kwayo, hamwe nibisabwa cyane cyane kumasoko akomeye, kandi biragoye kubona ibimenyetso byo gukira mugihe gito.
