Epichlorohydrin: Lub Tsib Hlis, kev lag luam epichlorohydrin txuas ntxiv tsis muaj zog thiab oscillating, feem ntau qhia qhov sib txawv ntawm thawj zaug thiab tom qab ntawd poob qis, thaum lub Tsib Hlis Hnub so, cov khoom siv raw cov kua chlorine broad rebound, muaj zog them nyiaj yug, ua ke nrog Jilin Shenhua, Daze, Sanyue, Huatai ntaus ntawv kom txo tau qhov tsis zoo los yog chaw nres tsheb, muab khoom thiab cov nqi tsim nyog rov qab los ntawm cov khoom lag luam, cov khoom lag luam epichlorohydrin txuas ntxiv. me ntsis nce siab, tab sis qhov kev thov qis qis rau kev txwv tsis pub muaj kev kawm, ua ke nrog East Tuam Tshoj kev lag luam chaw muaj ntau, huab cua nyob twj ywm, thawj ib nrab ntawm lub hli qhov chaw pib qhia tias "tight sab qaum teb sab qab teb xoob", kev ua lag luam maj mam ua tiav; nruab nrab, raws li qhov kev thov tseem yog lub teeb, thaum cov khoom siv raw cov kua chlorine thim rov qab, qhov chaw poob qis thiab lwm qhov chaw qis, ua ke nrog lub Hoobkas cov khoom lag luam siab, Shandong sawv cev ntawm lub Hoobkas txiav txim siab txiav cov nqi Hoobkas, tab sis cov nqes nqes mus rau kev tua nyob rau hauv Yuav tsum tau hedge, tus nqi poob rau ib hlis qis, Wanhua Phase II chaw nres tsheb, Sinochem rov qab ua lag luam, kev lag luam tsis zoo, kev ua lag luam zoo li Quanzhou. qhov kev thov qis qis rau lub sijhawm luv luv, tom qab rov qab los ntawm tsuas yog 200 yuan / ton, tuav ruaj khov thiab tos saib.

Ethylene oxide: Nyob rau lub Tsib Hlis, kev lag luam hauv tsev ntawm ethylene oxide feem ntau ruaj khov, thiab tus nqi tau hloov qis qis thaum kawg ntawm lub hli. Cov nqi ethylene txuas ntxiv poob rau lub hli, tshwj xeeb tshaj yog nyob rau hauv Asia, thiab tus nqi siab ntawm ethylene oxide maj mam txo qis. Nyob rau tib lub sijhawm, qhov kev xav tau qis qis thiab lub davhlau ya nyob twg txuas ntxiv tsis muaj zog, thiab kev txhawb nqa ntawm kev txais cov khoom muaj tsawg. Raws li tus nqi ntawm ethylene txuas ntxiv poob, kev lag luam kev xav thaum kawg ntawm lub hli, xws li kev poob siab, kev xa khoom hauv Hoobkas tsis zoo, kev lag luam kev lag luam tseem muaj teeb meem.

Polyether: Nyob rau lub Tsib Hlis, kev lag luam hauv tsev polyether muaj zog tom qab poob qis. Thaum pib ntawm lub hli yog hais txog mus rau lub Tsib Hlis hnub so, tab sis lub pre-hnub so stocking lub hom phiaj yog tsis muaj zog, lub qeeb pace ntawm shipments, nyiaj so koobtsheej xav tau tseem lub teeb, lub lag luam muaj zog tos-thiab-pom kev xav, nyob ze rau qhov kawg ntawm lub polyether ushered nyob rau hauv tsuas yog qhov yuav tsum tau mus ntxiv rau lub warehouse, tus tshiab ib zaug xwb kev hloov raws li me ntsis, qhov kev thov kev ua tau zoo nyob rau hauv lub caij nplooj ntoos zeeg, tab sis maj mam poob nqi. qhov kev thov yog ntau tshaj li muted, kom txog rau thaum lub thib ob ib nrab ntawm lub xyoo, nyob rau hauv tus nqi tseem tsis muaj zog, kev thov tau zoo dua, tab sis los ntawm Terminal recession, kev thov yog ib qho nyuaj rau tswj, thiab txaus mov, nrog rau cov kev cuam tshuam ntawm kev sib kis tseem muaj, qhov kev vam meej yog qhov nyuaj nrhiav tau, qhov kawg ntawm lub hli nyob rau hauv lub cyclic propylene nqi them nyiaj yug thiab tus nqi ntawm cov polyether procuryl nce mus txog me ntsis. zoo txhawb nqa me ntsis ntxiv.
