Uwitekaisoko ya propylene“Jinjiu” yakomeje kuzamuka kwayo mbere, maze isoko irenga ku 10000 (igiciro cya toni, kimwe hepfo). Dufashe nk'isoko rya Shandong, igiciro cy'isoko cyazamutse kigera ku 10500 ~ 10600 ku ya 15 Nzeri, kikaba cyiyongereyeho amafaranga 1000 kuva mu mpera za Kanama. Ku ya 20 Nzeri, yagabanutse igera ku mafaranga 9800. Mu bihe biri imbere, biteganijwe ko uruhande rutanga isoko ruziyongera, igihe cy’ibisabwa ntigikomeye, kandi oxyde ya propylene ihindagurika mu 10000.
Kwiyongera kwa propylene oxyde yongeye gutangira gutanga
Muri Kanama, mu Bushinwa hamaze kuvugururwa ibice 8 byose bya oxyde ya propylene, birimo ubushobozi bwa toni 1222000 / umwaka hamwe n’igihombo cya toni 61500. Muri Kanama, umusaruro w’uruganda rwa propylene oxyde yo mu rugo wari toni 293200, ukamanuka ku kwezi 2.17% ukwezi, naho ikoreshwa ry’ubushobozi rikaba 70.83%.
Muri Nzeri, uruganda rwa Sinochem Quanzhou propylene rwahagaritswe kugirango rushobore kubungabungwa, Tianjin Bohai Chemical, Changling, Shandong Huatai n’ibindi bice byongeye gutangira bikurikiranye, kandi Jinling yagabanijwe kugeza ku gice cya kabiri cy’imitwaro. Kugeza ubu, igipimo cya oxyde ya propylene kiri hafi 70%, kiri munsi gato ugereranije no muri Kanama.
Mu bihe biri imbere, Shandong Daze ya 100000 t / uruganda ruzakomeza umusaruro mu mpera za Nzeri, biteganijwe ko 300000 t / uruganda rwa Jincheng Petrochemical ruzashyirwa mu bikorwa mu mpera za Nzeri; Ibimera bya Jinling na Huatai birasubira mubikorwa intambwe ku yindi. Uruhande rutanga rwiyongera cyane, kandi abacuruzi barushijeho kwihanganira. Biteganijwe ko isoko ya propylene oxyde izerekana intege nke zo guhagarara mugihe hiyongereyeho ibicuruzwa bitangwa, hamwe ningaruka nke zo kumanuka.
Inkunga ya propylene oxyde yibikoresho byitezwe ko bigoye
Kubikoresho byo hejuru byibanze bya propylene na chlorine yamazi, nubwo "Jinjiu" yatangije isoko ryizamuka, biteganijwe ko bizoroha kugwa kuruta kuzamuka kumasoko azaza, bizagorana gushiraho imbaraga zikomeye kuri kumanuka.
Muri Nzeri, igiciro cya propylene, ibikoresho byo mu rwego rwo hejuru, byakomeje kwiyongera mu gihirahiro, ari nacyo cyatanze inkunga ikomeye ku isoko rya okiside ya propylene. Wang Quanping, umuyobozi mukuru wa Shandong Kenli Petrochemical Group, yavuze ko itangwa rya propylene mu gihugu ryakomeje kuba rito, ku buryo bigaragara ko mu majyaruguru y'uburengerazuba, hagati no mu burasirazuba bw'Ubushinwa. Byongeye kandi, ibikoresho bimwe na bimwe byo kubungabunga hepfo ya propylene, nka Tianjian Butyl Octanol, Dagu Epoxy Propane, na Kroll Acrylonitrile, byongeye kubaka. Kubwibyo, isoko ryasunitswe hejuru, inganda za propylene zagurishijwe neza, kandi ibarura rito ryatumye ibiciro bya propylene bizamuka.
Urebye imikorere yibice, kuruhande rumwe, Xintai Petrochemical na propylene yongeye gutangira, ariko ingaruka zabaye nkeya kubera gutinda kenshi. Muri icyo gihe, ubushobozi bushya bwo gukora bwa propane dehydrogenation ya propylene muri Shandong bwashyizwe mu bikorwa bitarenze uko byari byitezwe, kandi muri rusange wasangaga ugenzurwa. Ku rundi ruhande, mu gihe cya vuba, ibice bimwe na bimwe bikomeye byo mu majyaruguru y'uburengerazuba byahagaritswe kugira ngo bibungabungwe, kandi itangira rya propylene mu majyaruguru y'uburengerazuba ryaragabanutse kugera kuri 73.42%. Uruzinduko rwibicuruzwa bya peripheri byagabanutse cyane. Byongeye kandi, ibihingwa bimwe na bimwe byo mu majyaruguru y’iburengerazuba byabitse propylene ikenerwa n’umusaruro wo hanze, kandi itangwa rya peripheri ya periferique ryarushijeho gukomera.
Mu bihe biri imbere, imitwaro yinganda za propylene irahagaze neza, kandi nta gutegereza impinduka zikomeye mugutanga propylene. Uturere twa peripheri ya Shandong n'Uburasirazuba bw'Ubushinwa tuzakomeza kugemura neza. Hasi yimbere ikunda gucika intege hamwe nisahani, igahagarika ishyaka ryo kugura propylene kumanuka. Kubwibyo, isoko ya propylene iriho ubu iri mubihe bidakenewe no gukenerwa, ariko octanol yo hepfo, okiside ya propylene, acrylonitrile nizindi nganda byongereye umutwaro, kandi uruhande rukenewe rukeneye inkunga. Biteganijwe ko igiciro cya propylene gikurikiraho kizahinduka mugihe gito, hamwe no kuzamuka no kugabanuka.
Ikindi kintu kibisi, chlorine yamazi, nikintu gikomeye ku isoko. Umubare w’ibicuruzwa byo hanze y’ibikoresho bimwe na bimwe byo gufata neza inganda nini byagabanutseho gato, kandi bamwe mu bakora inganda zo muri Shandong rwagati ntibahungabanye, ibyo bikaba byafashaga isoko gukomeza kuzamuka ku rugero runaka. Inzira yo hasi yingufu zikomeye mubushinwa bwiburasirazuba yagaruwe, icyifuzo cyaragabanutse, kandi ibikoresho bimwe na bimwe byarahagaritswe kugirango bibungabunge. Ibicuruzwa byagabanutse. Ibihe byiza kuruhande rwibitangwa nibisabwa byarengeje urugero ku kuzamuka kw'isoko rya Shandong, bituma isoko rusange ryibanda ku isoko kuzamuka. Meng Xianxing yavuze ko hamwe no kugarura ibikoresho bigabanya umusaruro no kongera ibicuruzwa, igiciro cya chlorine y’amazi gishobora kugabanuka mu gihe cyakurikiyeho.
Isabwa rya okiside ya propylene iratinda kandi biragoye gutera imbere mugihe cyimpera
Polyether polyol nigicuruzwa cyingenzi cyo hepfo ya propylene oxyde nibikoresho fatizo bya synthesis ya polyurethane. Ubushobozi burenze urugero muri polyurethane yo murugo imbere yinganda, cyane cyane umuvuduko ukabije wisoko ryoroshye, ni nini.
Meng Xianxing yavuze ko muri Nzeri, bitewe n'ibiciro, isoko ryoroheje ryuzuye ifuro ryinshi ryazamutse, kandi inganda zikomeye zakomeje gushyigikira isoko, ariko imikorere yo hasi yari impuzandengo, kandi kugera hagati no hepfo byari bikiri hasi.
Kugeza ubu, sponge yo hepfo iragenda yiyongera gahoro gahoro, ikiguzi cyo hejuru kiracyakeneye koherezwa, hagati no hepfo bikomeza kugogora no gutegereza, kandi isoko rikomeye rikomeje kuba ryoroshye. Mu bihe biri imbere, nubwo amakuru mabi atarashyirwaho, abayakora benshi baracyafite umwanya kubera kugabanuka kw'ibiciro, kandi uruhare rwabo mugushyigikira ibikoresho fatizo byo hejuru ni bike.
Ku rundi ruhande, isoko yo hepfo yamashanyarazi yamashanyarazi yagumanye kuzamuka neza, kandi hagati no hepfo byakomeje kugura kubisabwa. Nubwo ibikorwa rusange byari munsi yigihe kimwe, byateye imbere ugereranije nigihembwe cya kabiri. Nubwo kwinjira muri "Jinjiu", nta mpinduka zigaragara zikenewe ku isoko, kandi uruganda rugena umusaruro rushingiye kubisabwa.
Mu bihe biri imbere, ibigo byo hasi birategereza-cyane-kureba, kandi ubushake bwabo bwo kugura ibicuruzwa bishya nibisanzwe. Mugihe cyibicuruzwa bidahwitse nubushoramari, ifuro ryinshi "Jinjiu" ntabwo aribyiza bihagije kugirango ushire imbaraga mumigezi.

Chemwinni uruganda rukora ibicuruzwa biva mu mahanga mu Bushinwa, biherereye mu gace ka Shanghai Pudong, hamwe n’urusobe rw’ibyambu, ama terminal, ibibuga by’indege ndetse n’ubwikorezi bwa gari ya moshi, hamwe n’ububiko bw’imiti n’ibyangiza muri Shanghai, Guangzhou, Jiangyin, Dalian na Ningbo Zhoushan, mu Bushinwa , kubika toni zirenga 50.000 z'ibikoresho fatizo bya chimique umwaka wose, hamwe nibitangwa bihagije, ikaze kugura no kubaza. imeri ya chemwin:service@skychemwin.comwhatsapp: 19117288062 Tel: +86 4008620777 +86 19117288062
