1,Isimo Semakethe: Ukuqina nokukhuphuka ngemuva kokuncipha kafushane

Ngemuva kweholide lemini lemini, imakethe ye-epoxy propane yawohlazeka kafushane, kepha yabe isiqala ukukhombisa umkhuba wokuzinza kanye nomkhuba omncane ophakeme. Lolu shintsho akuyona ingozi, kepha lithonywe yizici eziningi. Okokuqala, ngesikhathi samaholide, izinto eziphilayo zivinjelwe futhi umsebenzi wokuhweba uyancipha, okuholela ekunciphiseni okuzinzile ngamanani emakethe. Kodwa-ke, ngokuphela kweholide, imakethe yaqala ukubuyisa ubungqabavu, kanti amanye amabhizinisi okukhiqiza aqediwe ukulungiswa, okuholela ekwehliseni ekuhlinzekeni emakethe nasekuqhubeni amanani.

Ngokuqondile, kusukela ngoMeyi 8, i-Maytream Spot Exclow Exclow Ex Exfer Factory Price in Shendong esifundeni i-Shandong ikhuphuke ku-9230-9240 yuan / ton, ukukhuphuka kwe-50 yuan / ton kuqhathaniswa nesikhathi samaholide. Yize lolu shintsho alubalulekanga, lubonisa ukushintshwa kwemizwa yemakethe kusuka ekubeni abadideli ukuba baqaphele futhi benethemba.

2,I-East China Nise: Isimo esishubile sinciphise kancane kancane

Ngokombono we-Supply Side, ekuqaleni bekulindeleke ukuthi isitshalo sethani / le-HPPO le-HPPO le-Ruiheng lizophinde liqale ukusebenza ngemuva kweholide, kepha kube nokubambezeleka esimweni sangempela. Ngasikhathi sinye, unyaka wethani / unyaka we-200000 PO / SM / SM Plant of Sininochem Quanzhou okwesikhashana ngesikhathi samaholide futhi kulindeleke ukuthi abuyele kokujwayelekile maphakathi nenyanga. Izinga lokusetshenziswa kwamandla okusebenza kwamanje kwemboni lingama-64.24%. Isifunda sase-East China sisebhekene nenkinga yempahla enganele etholakalayo etholakala endaweni yesikhashana, kanti amabhizinisi aphansi anesidingo esithile sesidingo esiqinile ngemuva kokuqalisa kabusha umsebenzi ngemuva kweholide. Esimweni lapho kunomehluko wentengo ebalulekile phakathi kweNyakatho naseningizimu yePropane ye-Epoxy, ukwabiwa kwezimpahla ezivela enyakatho kuya eningizimu kuncishiswe yi-Factories enyakatho ngesikhathi samaholide, futhi imakethe yaqala ukuphenduka buthaka ukuze uqine, ngokwenyuka okuncane izingcaphuno.

Esikhathini esizayo, izinto ezintsha ze-Ruiheng kulindeleke ukuthi ziqale ukuthumela kancane kancane kule mpelasonto, kepha ukukhula kwevolumu ejwayelekile kuzothatha isikhathi. Ukuqalisa kabusha kwama-petrochemical se-satellite kanye nokugcinwa kwesigaba saseZhenhai esihlelelwe amathuba angaba nguMeyi 20, kanti okubili ngokuyisisekelo okugcwele, okuzokhiqiza umphumela othile wokudubula wokuhlinzekwa ngaleso sikhathi. Yize kukhona okwakulindelekile ekwandeni esifundeni sase-East China ngokuzayo, ukwanda kwangempela kwevolumu kulinganiselwe kulenyanga. Ukuhlinzekwa kwe-Spot eqinile kanye nomehluko wamanani aphezulu kulindeleke ukuthi ancishiswe ngokulinganayo ngasekupheleni kwenyanga, futhi kancane kancane angabuya kokujwayelekile ngoJuni. Ngalesi sikhathi, ukulethwa kwezimpahla eziqinile esifundeni sase-East China kulindeleke ukuthi kuqhubeke ukusekela imakethe ye-epoxy ephelele, ngegumbi elinganiselwe lokuguquguquka kwentengo ukwehla.

3,Izindleko ezibonakalayo ezingavuthiwe: ukuguquguquka okulinganiselwe kepha kudinga ukunakwa

Ngokombono wezindleko, intengo ye-propelene igcine umkhuba ozinzile ezikhathini zamuva. Ngesikhathi seholide, intengo ye-chlorine ewuketshezi ebuyiselwe ezingeni eliphakeme kungakapheli unyaka, kepha ngemuva kweholide, ngenxa yokumelana nezimakethe ezansi, intengo yathola ukwehla okuthile. Kodwa-ke, ngenxa yokushintshashintsha kwamadivayisi ngamanye esizeni, kulindeleke ukuthi intengo ye-chlorine ewuketshezi ingaphindaphindeka kancane engxenyeni yesibili yesonto. Njengamanje, izindleko ze-theory ze-chlorohydrin indlela zihlala zingaphakathi kohlu lwe-9000-9100 yuan / ton. Ngokwanda okuncane kwentengo ye-Epichurohydrin, indlela ye-chlorohydrin isiqalile ukubuyela esimweni senzuzo encane, kepha lesi simo senzuzo asisenele ukwakha ukwesekwa kwemakethe okuqinile.

Kukhona amathuba okuba umkhuba ongaphezulu ophakeme ngentengo ye-propylene ngokuzayo. Ngaleso sikhathi, uma ucubungula amacebo wesondlo amayunithi athile embonini ye-chlor alkali ngoMeyi, kulindeleke ukuthi izindleko zemakethe zizokhombisa umkhuba othile ophakeme. Kodwa-ke, njengoba ukwesekwa kokwanda okuncane kwabahlinzeki buba buthaka phakathi kwezinyanga ezizayo, ukwesekwa kwezindleko zemakethe kungakhula kancane kancane. Ngakho-ke, sizoqhubeka nokubheka ukuthuthukiswa kwalo mkhuba.

4,I-Downstream Isidingo: Ukugcina Ukukhula Okuzinzile Kodwa Ukuthola Ukushintshashintsha

Ngokuya ngesidingo esiphansi, ngemuva kweholide lemini lemini, impendulo evela embonini ye-polythere ikhombisa ukuthi inani lama-oda amasha lilinganiselwe okwesikhashana. Ngokukhethekile, ivolumu ye-oda esifundeni saseShandong lihlala lisezingeni eliphakeme, ngenkathi ukufunwa kwemakethe e-East China kuvela kubanda kakhulu ngenxa yentengo ephezulu ye-epoxy propane, kanye namakhasimende wokugcina abamba isimo sokulinda esibonakalayo. Amanye amakhasimende anentshisekelo yokulinda ukwanda kokuhlinzekwa kwePropane ye-Epoxy ukufuna amanani amahle, kepha ukuthambekela kwamanani emakethe yamanje kuthambekele ekuweni kodwa kunzima kakhulu ukuwa, futhi amakhasimende amaningi asemqoka asakhetha ukulandela futhi athenge. Ngasikhathi sinye, amanye amakhasimende akhule ukumelana namanani aphezulu futhi akhethe ukunciphisa okuncane umthwalo wokukhiqiza ukuzivumelanisa nemakethe.

Ngokombono wezinye izimboni eziphansi, i-plylene glycol dimethyl ester imboni njengamanje isesimweni senzuzo nokulahleka kwamandla emboni, kanti izinga lokusetshenziswa kwamandla emboni lihlala lizinzile. Kubikwa ukuthi ngesikhathi esingaphakathi kwenyanga, ukuhlanganisa uJintai kuhlela ukwenza ukugcinwa kokupaka, okungaba nomthelela othile ekufunweni jikelele. Sekukonke, ukusebenza kwe-DownStream 4.

5,Izitayela zesikhathi esizayo

Esikhathini esifushane, izinto ezintsha ze-Ruiheng zizoba umnikelo oyinhloko ekwandeni kwevolumu yezimpahla kule nyanga, futhi kulindeleke ukuthi lokhu kukhuphuka kukhishwe kancane kancane emakethe ngezigaba eziphakathi nendawo. Ngasikhathi sinye, eminye imithombo yokuhlinzekwa izokhiqiza umphumela othile wokuqothula, okwenza inani eliphakeme levolumu ligxile kuJuni. Kodwa-ke, ngenxa yezinto ezithandekayo ohlangothini lokuhlinzekwa, yize ukwesekwa maphakathi nezinyanga kuze kube sekwedlule izinyanga kungahle kube buthaka, kulindeleke ukuthi kulindele izinga elithile lokusekelwa emakethe. Ngaphezu kwalokho, ngohlangothi lwezindleko ezizinzile futhi eziqinile, kulindeleke ukuthi intengo ye-epoxy isebenza ikakhulukazi ebangeni lama-9150-9250 yuan / ithoni ngoMeyi. Ohlangothini lwemfuno, kulindeleke ukuthi wethule inkambiso yokulandela eqinile futhi eqinile. Ngakho-ke, imakethe kufanele ibheke kakhulu ukuguquguquka nokuhlengwa kwamadivayisi asemqoka afana ne-Ruiheng, i-satellite, kanye noZhenhai ukuhlola izitayela ezengeziwe zemakethe.

Lapho kuhlaziya ukuthambekela kwemakethe yesikhathi esizayo, kufanele kubhekwe ukunakwa okukhethekile ezingozini ezilandelayo: Okokuqala, kungahle kube nokungaqiniseki ngesikhathi sokukhuphuka kwensiza, okungenzeka kube nomthelela oqondile ekunikezelweni kwemakethe; Okwesibili, uma kunengcindezi ohlangothini lwezindleko, kunganciphisa umdlandla wamabhizinisi ukuqala ukukhiqizwa, ngaleyo ndlela kuthinte ukuqina kokuhlinzekwa kwemakethe; Okwesithathu ukuqaliswa kokusetshenziswa kwangempela ohlangothini lwesidingo, okubuye kube ngesinye sezici ezibalulekile ukunquma izitayela zentengo yemakethe. Ababambiqhaza bemakethe kufanele babhekane kakhulu nezinguquko kulezi zinto zobungozi ukuze zenze izinguquko ezifika ngesikhathi.
