Kuyambira chakumapeto kwa Epulo, msika wapakhomo wa epoxy propane walowanso m'chizoloŵezi chophatikizana, ndi malo ofunda amalonda komanso masewera ofunikira pamsika.

Mbali yogulitsira: Zhenhai refining and chemical plant ku East China sichinayambenso, ndipo makina a satellite petrochemical atsekedwa kuti athetse kusowa. Kuchita kwazinthu zopezeka pamsika waku East China kungakhale kolimba pang'ono. Komabe, kupezeka pamsika wakumpoto ndikochuluka, ndipo mabizinesi opanga nthawi zambiri amatumiza katundu, zomwe zimapangitsa kuti pakhale kuchulukirachulukira kwazinthu; Pankhani ya zopangira, msika wa propylene watsika, koma pakali pano mitengo imakhalabe yotsika. Pakatha pafupifupi sabata imodzi yazovuta, msika wamadzimadzi wa chlorine wagwa pansi pa kukakamizidwa kuti apereke ndalama zogulitsa mu theka lachiwiri la chaka, zomwe zimapangitsa kuchepa kwakukulu kwa ndalama zothandizira mabizinesi a PO pogwiritsa ntchito njira ya chlorohydrin;

Mbali yofunikira: Kufuna kwapansi kwa polyether ndikwathyathyathya, ndi chidwi chofuna kufufuza msika, kutumiza kokhazikika kuchokera kwa opanga osiyanasiyana, makamaka kutengera malamulo operekera, kuphatikizapo EPDM yaposachedwa yamtengo wapatali. Malingaliro ogula a mabizinesi nawonso amakhala osamala, makamaka kuti asunge zofuna zolimba.

Ponseponse, msika wa propylene kumapeto kwazinthu zopangira ndi wofooka, pomwe msika wamadzimadzi wa klorini ukadali wofooka, zomwe zimapangitsa kuti zikhale zovuta kuwongolera kuthandizira kumapeto kwazinthu zopangira; Pankhani ya kaphatikizidwe, chipangizo cha Zhenhai chitha kuyambiranso koyambirira kwa Meyi, ndipo zida zina zowunikiranso zikukonzekera kuyambiranso ziyembekezo zawo mu Meyi. Pakhoza kukhala kuwonjezeka kwina kwa chakudya mu May; Kufunika kwa msika wakumunsi wa polyether ndikokwanira, koma sabata ino zitha kulowa pang'onopang'ono tchuthi cha Meyi Day chisanachitike, ndipo mbali yofunikirayo ingakhale ndi chilimbikitso china. Chifukwa chake, ponseponse, msika wa epoxy propane ukuyembekezeka kuyenda bwino pakanthawi kochepa.
