Amaxabiso eoyile ye-WTI ayaqhubeka nokuhla malunga ne-$45, kodwa utshintsho lwakutshanje embindini womxhuzulane lucacile. Ukunyuka kwesibonelelo seSaudi Arabia kwiimarike zaseAsia emva kwentlanganiso ye-Opec kubonakalise ithemba layo malunga nemfuno yemarike.
Urhulumente kaTrump ubhenele kwiNkundla ePhakamileyo emva kokuba ubungqina obutsha butyhile ukuba bekukho iingxaki zokubala kunyulo nangona kutshintshelwe amandla emva konyulo lwase-US. Isicwangciso soncedo lwezoqoqosho sase-US sobhubhane siphinde saxoxwa, kwaye imakethi ijonge phambili kwisiphumo.
Ubhubhane wehlabathi usasasazeka. Bekukho iindaba ezilungileyo nezimbi kwicala le-vaccine, kwaye ngokubanzi, umhla wokuqaliswa kwayo usondela.
Ukuthunyelwa kwamanye amazwe eTshayina ngoNovemba (ngokwe-DOLLAR) kunyuke nge-21.1% ukusuka kunyaka ophelileyo, kulindeleke ukuba kunyuke nge-9.5%, xa kuthelekiswa ne-11.4% ukusuka kunyaka ophelileyo, kwaye ukuthunyelwa kwamanye amazwe kunyuke nge-4.5% ukusuka kunyaka ophelileyo, kulindeleke ukuba kunyuke nge-4.3% ukusuka kunyaka ophelileyo; Intsalela yorhwebo ifikelele kwinqanaba eliphezulu leedola ezingama-75.42 ezigidigidi, ukusuka kwi-$58.44 ezigidigidi. Ngokwe-yuan, ukuthunyelwa kwamanye amazwe kunyuke nge-14.9%, ukusuka kwi-7.6 ekhulwini.
Uqikelelo lwemarike lweekhemikhali ezithile:
1. Uqikelelo: Ubungakanani be-methanol ekujikelezeni kwezibuko bunyuke kakhulu ngempelaveki ephelileyo. Uluhlu lwabavelisi kwiindawo zemveliso ezisemantla luphantsi kwaye izinga lokusebenza lilonke alitshintshi kangako. Ukuba akukho zinto zinkulu ezintle, kulindeleke ukuba i-methanol isacutshungulwa kakhulu yi-shock kule veki.
2. Uqikelelo: i-toluene, i-xylene, izityalo zasekhaya ziqala phantsi, imfuno iyonke ibuthathaka. Iimpahla zezibuko ziyaqhubeka nokuhla. Ukuguquguquka kwexabiso leoyile kunamandla. Kulindeleke ukuba kule veki imarike ye-toluene yasekhaya, i-xylene inyuke kancinci.
3. Uqikelelo: Izinga lokusebenza kwabavelisi bePVC liphucukile, kodwa i-oda langaphambili alikagqitywa, kwaye ubungakanani bendawo ekhoyo kwimarike buncinci. Emantla, ngenxa yokhuseleko lokusingqongileyo kunye nezinye izizathu, imfuno ephantsi inciphile kancinci. Amaxabiso aphezulu angqubana kwindawo yokuthengisa kodwa kufuneka nje ukuba ihlale izinzile. Ekupheleni kweveki ephelileyo, ukunyuka kwemarike yemali kuye kwehla, kulindeleke ukuba imakethi iqhubeke nokuguquguquka okuphezulu kule veki, kufuneka kuqatshelwe ukuba ikhontrakthi yexesha elizayo kaJanuwari isesemngciphekweni wokuguquguquka okukhulu.
4. Uqikelelo: Kwiveki ephelileyo, unikezelo lwe-acrylic acid kunye ne-ester luqinile kwaye izinto ezisetyenzisiweyo ezinxulumene noko zinyuka phantsi kweendaba ezilungileyo ukuze ziqhubeke nokuqina. Okwangoku, unikezelo lwe-spot lusaqinile, abavelisi abayi kulinciphisa ixabiso, kufuneka nje balandelele imeko esezantsi. I-acrylic acid kunye ne-ester kulindeleke ukuba imarike ye-spot iqhubeke nokusebenza okuqinileyo kokugqiba.
5. Uqikelelo: Amaxabiso e-maleic anhydride ehle kakhulu kwaye ngokukhawuleza kwiveki ephelileyo, ephinda imeko ye-roller coaster. Ngenxa yokulindela imfuno eqinileyo esezantsi, abavelisi be-maleic anhydride banepleyiti yokutywina ukuze bandise intshukumo. Ukunyuka kulindeleke ukuba kuqhubeke kule veki.
6, ukuvalwa kwezixhobo zangaphandle ngenxa yokusilela kwazo, kunye nenkxaso enamandla yeendleko, imarike ye-styrene yamkele ukuphinda kubuye ekuqaleni kweveki. Nangona kunjalo, iiyunithi zasekhaya ziye zangena kwimveliso, kwaye imfuno elandelayo ibuthathaka, kuqikelelwa ukuba imarike ye-styrene iya kuncitshiswa kwixesha elifutshane.
7. Ukungabikho kolungelelwaniso phakathi kokunikezelwa kunye nemfuno, kuqikelelwa ukuba imakethi ye-acetone ayizukuba nendawo ingako yokunyuka kwexesha elifutshane.
8. Kuqikelelwa ukuba imakethi ye-DOP isenokuphela kwixesha elifutshane ngenxa yokukhululwa kweendleko kunye nokucotha kwemfuno.
9, amathuba okuba kubekho ithuba ukuba akukho nto ilungileyo ifunekayo, qikelela ukuba ukunyuka kwexesha elifutshane kwemarike ye-phthalic anhydride kunzima ngakumbi.
10. Ngokusekelwe kwimeko yokungabikho kobonelelo kunye nemfuno, kuqikelelwa ukuba imakethi ye-MMA inokutshintshatshintsha kuluhlu oluncinci kwixesha elifutshane.
11. Inkxaso enamandla yeendleko, kodwa ukubonelela ngemveliso yasekhaya kulindeleke ukuba kwande. Kuqikelelwa ukuba kwixesha elifutshane, imakethi ye-phenol inokujongana ikakhulu neengxolo.
12, ulungelelwano oluhle, uloyiko lwemarike ye-PTA oluqinileyo kwiveki ephelileyo. Nangona kunjalo, ngenxa yeziseko ezibuthathaka, kuqikelelwa ukuba imarike ye-PTA iya kuncitshiswa kwixesha elifutshane.
13, inkxaso yeendleko inamandla, kodwa indima yokutyhala esezantsi ibanzi, kuqikelelwa ukuba imarike ye-benzene ecocekileyo kwixesha elifutshane okanye iya kuba yintsebenziswano eqinileyo.
14. Icala lokubonelela libonisa into ethile elungileyo, kodwa ngenxa yokungabikho kwentsebenziswano esebenzayo nemfuno, kuqikelelwa ukuba imakethi yeTianjiao iya kugungqiswa kakhulu kwixesha elifutshane, inike ingqalelo kwisikhokelo sezinto ezingaphandle.
Kwiveki ephelileyo, imakethi ye-acetic acid yasekhaya iqhubekile nokunyuka. Okwangoku, umzi-mveliso sele uxinene ekuhanjisweni, kunye nokuvalwa okungalindelekanga kwesityalo se-BP eNanjing, icala lokubonelela liqiniswe ngakumbi. Nangona kunjalo, ngenxa yokunyuka ngokukhawuleza kwexabiso lemakethi kunye nokumelana okunamandla kumlambo osezantsi, kulindeleke ukuba imakethi inciphe kule veki xa ithelekiswa neveki ephelileyo.
16. Imarike ye-butanone yasekhaya inyuke kakhulu kwiveki ephelileyo. Umzi-mveliso awunaxinzelelo lwempahla, kwaye imeko yophando esezantsi ifuna ukuphucula, ingena kwimarike kwaye ithengise izinto ezidityanisiweyo, eziqhutywa yimeko yokuthenga, kulindeleke ukuba imakethi isenokunyuka kule veki.
Ngomhla we-17 kweyoMdumba, kwiveki ephelileyo, ukukhwankqiswa kwemarike ye-ethylene glycol yasekhaya kunamandla. Ukuhlanganiswa kokuguquguquka kwamaxabiso eoyile yamazwe ngamazwe; Okwangoku, ukuqhubeka kwezibuko ukuya kwelinye kuncinci kakhulu; Nangona ezinye iiyunithi ze-ethylene glycol ziqaliswe kwakhona, bekukho ezinye iiyunithi ezilungiswayo kwaye zincitshiswa kakubi, kwaye ukunyuka kokunikezelwa bekungaphantsi kunokulindelekileyo. Isiphelo se-polyester esisezantsi siqala ukugcina ukusebenza okuphezulu nokuzinzileyo kwemfuno. Kulindeleke ukuba ukuhlanganiswa kwesithuba se-glycol yasemva kwemini kunokwenzeka ukuba kube namandla.
18, kwiveki ephelileyo, ukubuyiselwa kwesimo sokuguquguquka kwemarike ye-diethylene glycol yasekhaya. Ukuhlanganiswa kokuguquguquka kwamaxabiso eoyile yamazwe ngamazwe; Okwangoku, umthwalo wokuqala wokufakelwa kwasekhaya uhlala uphantsi, ukuzaliswa kwakhona kobuninzi beeport-to-ship kulinganiselwe, kwaye imozulu engathandekiyo ichaphazela ukuhla okuqhubekayo kwempahla yeeport, ngoko ke ishishini le-resin elisezantsi lithambekele ekubeni buthathaka. Ukuhlanganiswa koxinzelelo lwemarike kulindeleke ukuba kube nokwenzeka ngakumbi kule veki.
19. Ukuhlanganiswa kokuguquguquka kwamaxabiso eoyile yamazwe ngamazwe; Indawo yokunyusa ikamva ephezulu; Uluhlu lwezinto ezisetyenzisiweyo zePetrochemical lunyukile xa kuthelekiswa nexesha elidlulileyo; Ingxabano ephezulu esezantsi, kufuneka nje uthenge; Izinga lokusebenza kwamashishini asekhaya liphezulu, uxinzelelo lokubonelela lusekhona. Ukuqukumbela, kulindeleke ukuba ukuhlanganiswa kokuguquguquka kwemarike ye-PE yasekhaya kule veki kwenzeke.
20. Ukuhlanganiswa kwexabiso leoyile yamazwe ngamazwe ngenxa yokuguquguquka; Ikamva linyukile; Izinga lokususwa kweekhemikhali ezisebenzisa ipetroli liyehla; Imfuno esezantsi yexesha lokuphumla kwemveli iya kufika, kufuneka nje kuthathwe iimpahla; Ilahleko yokugcinwa kweeyunithi ayitshintshi kangako. Ukushwankathela, kulindeleke ukuba imakethi yePP kule veki inciphise amathuba okuhlanganiswa.
