1,Maphakathi no-Okthoba, intengo ye-epoxy propane yahlala ibuthakathaka

Maphakathi no-Okthoba, intengo yemakethe ye-epoxy propane yasekhaya yahlala ibuthakathaka njengoba bekulindelekile, ikhombisa umkhuba obuthakathaka wokusebenza. Lo mkhuba uthonywa kakhulu imithelela embaxambili yokwanda okuqinile ohlangothini lokuhlinzeka kanye nohlangothi lwesidingo olubuthakathaka.

2,Uhlangothi lokunikezela lukhula kancane kancane, kuyilapho uhlangothi lwesidingo lusivivi

Muva nje, ukwanda komthwalo kwamabhizinisi afana ne-Sinopec Tianjin, i-Shenghong Hongwei, i-Wanhua Phase III, ne-Shandong Xinyue kukhulise kakhulu ukunikezwa kwemakethe kwe-epichlorohydrin. Ngaphandle kwendawo yokupaka nokugcinwa kahle kwe-Jinling e-Shandong kanye nokusebenza kokunciphisa umthwalo kwe-Huatai e-Dongying, ukunikezwa sekukonke kwe-epoxy propane e-China kubonise ukukhuphuka okuqinile ngenxa yokuthi lawa mabhizinisi anohlu lwezinto ezithengiswayo. Kodwa-ke, uhlangothi lwesidingo aluzange lube namandla njengoba bekulindelekile, okuholela emdlalweni obuthakathaka phakathi kokunikezwa nokufunwa, futhi intengo ye-propylene oxide yehla ngenxa yalokho.

3,Inkinga yokuguqulwa kwenzuzo iya ngokuya iba nkulu, futhi ukwehla kwentengo kulinganiselwe

Ngokuncipha kwamanani e-epoxy propane, inkinga yokuguqulwa kwenzuzo iye yaba nzima kakhulu. Ikakhulukazi phakathi kwezinqubo ezintathu ezivamile, ubuchwepheshe be-chlorohydrin, obebunenzuzo ekuqaleni, sebuqale ukulahlekelwa inzuzo enkulu. Lokhu kukhawulele ukwehla kwentengo ye-epichlorohydrin, futhi izinga lokwehla lihamba kancane. Isifunda sase-East China sithintwe indali enenani eliphansi yezimpahla ze-Huntsman, okubangele isiphithiphithi samanani kanye nezingxoxo zokwehla, eziqhubeka nokwehla okusha ngonyaka. Ngenxa yokulethwa okugxilile kwama-oda angaphambi kwesikhathi kwamanye amafekthri angaphansi kwesifunda saseShandong, isasasa lokuthenga i-epoxy propane lisamukeleka, futhi intengo izinzile uma kuqhathaniswa.

4,Okulindelwe amanani emakethe kanye namaphuzu empumelelo engxenyeni yokugcina yonyaka

Ukungena ngasekupheleni kuka-Okthoba, abakhiqizi be-epoxy propane bafuna amaphuzu okuphumelela emakethe. Uhlu lwamafekthri asenyakatho lusebenza ngaphandle kwengcindezi, futhi ngaphansi kwengcindezi eqinile yezindleko, umqondo wokunyusa amanani uya ngokuya ukhula kancane kancane, uzama ukushayela isidingo esingezansi sokulandelela ngokukhuphuka kwamanani. Ngaso leso sikhathi, inkomba yezinga lokuthumela izimpahla ezithunyelwa ngaphandle yaseShayina yehle kakhulu, futhi kulindeleke ukuthi izithiyo zokuthumela ngaphandle komfula kanye neziphetho zizokwehla kancane kancane, futhi umthamo wokuthekelisa uzokhula kancane kancane. Ukwengeza, ukusekelwa kwephromoshini ye-Double Eleven kuphinde kube nesimo sengqondo sokuqaphela isimo sesidingo esiphuthumayo sasekhaya. Kulindeleke ukuthi amakhasimende okugcina ahlanganyele ekuziphatheni kokukhetha isidingo esiphansi sokugcwaliswa kabusha engxenyeni yokugcina yonyaka.

5,Ukubikezela Amathrendi Amanani Azayo

Ngokucabangela lezi zici ezingenhla, kulindeleke ukuthi kube nokukhuphuka okuncane kwentengo ye-epoxy propane ngasekupheleni kuka-Okthoba. Kodwa-ke, uma kubhekwa ukuthi i-Jinling e-Shandong izoqala ukukhiqiza ekupheleni kwenyanga kanye nesimo esiphelele sesidingo esibuthakathaka, ukusimama kokulandelela okufunwayo kulindeleke ukuthi kungabi nathemba. Ngakho-ke, ngisho noma intengo ye-epichlorohydrin ikhuphuka, indawo yayo izoba nomkhawulo, okulindeleke ukuthi ibe cishe ku-30-50 yuan/ton. Ngokulandelayo, imakethe ingase ishintshele ekuthunyelweni okuzinzile, futhi kukhona okulindelekile ukwehla kwentengo ekupheleni kwenyanga.

Kafushane, imakethe yasekhaya ye-epoxy propane ibonise ukuthambekela kokusebenza okubuthakathaka maphakathi no-Okthoba ngaphansi komdlalo wesidingo esibuthakathaka. Imakethe yesikhathi esizayo izothonywa izici eziningi, futhi kukhona ukungaqiniseki kumathrendi amanani. Abakhiqizi badinga ukuqapha ngokucophelela amathrendi emakethe futhi balungise kalula amasu okukhiqiza ukuze baphendule izinguquko zemakethe.
