Kusukela ngoNovemba, imakethe yasekhaya yonke ye-epoxy propane ibonise ukuthambekela kokwehla okubuthakathaka, futhi ububanzi bentengo buye bancipha. Kuleli sonto, imakethe idonswe phansi ohlangothini lwezindleko, kodwa kwakungakabi bikho amandla aqondisayo, ukuqhubeka nokusimama emakethe. Ngasohlangothini lokunikezela, kukhona ukuguquguquka ngakunye nokwehliswa, futhi imakethe ivulekile. NgoNovemba, kwakungekho mkhuba wemakethe obalulekile, futhi ukushintshashintsha kwentengo bekuncane kakhulu. Ukuthunyelwa kwefekthri phakathi nenyanga bekuyisicaba, futhi uhlu lwamagama lwaluphakathi nendawo, okubonisa ukuthi kuningi ngokuqhathaniswa.

Ngokombono wohlangothi lokunikezela, ukuhlinzekwa kwasekhaya kwe-epoxy propane kusezingeni elimaphakathi phakathi nonyaka. Kusukela ngoNovemba 10th, ukukhiqizwa kwansuku zonke bekungamathani ayi-12000, ngenani lokusebenzisa amandla angama-65.27%. Njengamanje, indawo yokupaka i-Yida ne-Jincheng endaweni ayikavulwa, futhi isigaba sesibili se-CNOOC Shell besisesimweni sokulungiswa okuqhubekayo inyanga yonke. I-Shandong Jinling ibilokhu imile ukuze ilungiswe ngokulandelana kwayo ngomhla ka-1 Novemba, futhi okunye ukusungula kuthengiswa okwamanje. Ngaphezu kwalokho, bobabili i-Xinyue kanye ne-Huatai bahlangabezane nokuguquguquka kwesikhashana futhi baphinde bagcwala ezinsukwini zokuqala. Phakathi nenyanga, ukuthunyelwa okuvela embonini yokukhiqiza kuyisilinganiso, futhi uhlu lwamagama luphakathi nendawo, kanti ngezinye izikhathi lungaphansi kwengcindezi. Ngokwengezwa kokuhlinzekwa kwedola laseMelika lase-East China, isimo siningi uma kuqhathaniswa.

Ngokombono wezindleko, izinto zokusetshenziswa eziyinhloko i-propylene kanye ne-chlorine ewuketshezi kubonise ukuthambekela okukhuphukayo ezinsukwini zakamuva, ikakhulukazi intengo yepropylene eShandong. Ithintwe ukuncipha kohlangothi lokuhlinzekwa kwezidingo kanye nesidingo esiqhubekayo, inyuke kakhulu ekuqaleni kwaleli sonto, ngokunyuka kwansuku zonke okungaphezu kwama-yuan angu-200/ton. Indlela ye-epoxy propane chlorohydrin kancane kancane yakhombisa ukulahleka phakathi nesonto, yase iyeka ukuwa nokuzinza. Kulo mzuliswano wemakethe, uhlangothi lwezindleko lusekelwe ngokuphumelelayo yimakethe ye-epoxy propane, kodwa ngemva kokuyeka ukwehla, uhlangothi lwezindleko lusabonisa umkhuba okhuphukayo. Ngenxa yempendulo elinganiselwe evela ohlangothini lwesidingo, imakethe ye-epoxy propane ayikaqini kabusha kuze kube manje. Njengamanje, amanani entengo ye-propylene ne-liquid chlorine zombili ziphezulu uma kuqhathaniswa, nokwehla okukhulu kwamanani kawoyela ongahluziwe kanye nokufinyeleleka okulinganiselwe kwe-propylene kanye ne-liquid chlorine. Kungase kube nzima ukugcina amanani aphezulu amanje esikhathini esizayo, futhi kukhona okulindelekile ukwehla kwempahla.

Ngasohlangothini lwesidingo, isizini ephakeme yendabuko ye-“Golden Nine Silver Ten” isebenze kancane kancane, ngoNovemba ikakhulukazi kube isizini yangaphandle yendabuko. Ama-oda e-polyether aphansi ayisilinganiso, futhi sibukele ukuguquguquka kwentengo emakethe yokuvikela imvelo kuncane. Ngesikhathi esifanayo, ngaphandle kwezisekelo ezinhle ezisobala, umuzwa wokuthenga ubulokhu uqaphile futhi ugxile ekufuneni. Ezinye izimboni ezisezansi nomfula njenge-propylene glycol kanye ne-flame retardants zivame ukubhekana nesikhathi sokuphumula ngenxa yokuncintisana okuphezulu kanye nenzuzo embi. Izinga eliphansi lamanje lokusetshenziswa kwamandla okukhiqiza lenza kube nzima ukunikeza ukwesekwa okusebenzayo kokuvikelwa kwemvelo. Ekupheleni konyaka, amabhizinisi abe nokucatshangelwa okwengeziwe ngokwamukela ama-oda, futhi abenomkhawulo ezinhlelweni zawo zangaphambi kwesikhathi ngenxa yemakethe eningi endaweni yesigaba sesithathu. Sekukonke, impendulo yetheminali yokulandelela yohlobo lwebhendi imaphakathi.

Uma sibheka phambili ekusebenzeni kwemakethe kwesikhathi esizayo, kulindeleke ukuthi imakethe ye-epoxy propane ihlale iguquguquka futhi ihlanganisa phakathi kwebanga elingu-8900 kuya ku-9300 yuan/ton ekupheleni konyaka. Umthelela wokuguquguquka ngakunye kanye nokufinyela ohlangothini lokuhlinzeka emakethe unomkhawulo, futhi nakuba uhlangothi lwezindleko lunomphumela oqinile wokuphakamisa, kusenzima ukushayela ubheke phezulu. Impendulo evela ohlangothini lwesidingo inomkhawulo, futhi ekupheleni konyaka, amabhizinisi anokucatshangelwa okwengeziwe ekutholeni ama-oda, okuholela ezinhlelweni zesitoko esilinganiselwe kusengaphambili. Ngakho-ke, kulindeleke ukuthi imakethe izohlala imile esikhathini esifushane. Kodwa-ke, kuyadingeka ukunaka ukuthi ingabe kukhona ukuthambekela kokuvalwa kwesikhashana nokwehliswa okungekuhle kwamanye amayunithi okukhiqiza ngaphansi kwengcindezi yezindleko, nokunaka inqubekelaphambili yokukhiqizwa kwe-Ruiheng New Materials (Zhonghua Yangnong).
