Amanani kawoyela e-WTI ayaqhubeka nokwehla cishe ngama-$45, kodwa ushintsho lwakamuva phakathi kwentengo yamandla lusobala. Ukwenyuka kwesiphakamiso seSaudi Arabia sezimakethe zase-Asia ngemuva komhlangano we-Opec kubonise ithemba layo ngesidingo semakethe.
Uhulumeni kaTrump udlulisele icala eNkantolo Ephakeme ngemuva kokuba ubufakazi obusha buveze ukuthi kube nezinkinga zokubala okhethweni naphezu kokushintsha kwamandla ngemuva kokhetho lwase-US. Uhlelo losizo lwezomnotho lwase-US lwalolu bhubhane luphinde lwaxoxwa, futhi imakethe ibheke phambili kumphumela.
Ubhubhane lomhlaba wonke lusasakazeka. Kube nezindaba ezinhle nezimbi mayelana nomgomo, futhi ngokuvamile, usuku lokuqaliswa kwawo selusondele.
Ukuthunyelwa kwezimpahla eShayina ngoNovemba (ngokwe-DOLLAR) kukhuphuke ngo-21.1% kusukela onyakeni odlule, kulindeleke ukuthi kukhuphuke ngo-9.5%, uma kuqhathaniswa no-11.4% kusukela onyakeni odlule, kanti ukuthunyelwa kwezimpahla kwamanye amazwe kukhuphuke ngo-4.5% kusukela onyakeni odlule, kulindeleke ukuthi kukhuphuke ngo-4.3% kusukela onyakeni odlule; Inzuzo yokuhweba ifinyelele irekhodi eliphezulu lama-$75.42 billion, kusukela ku-$58.44 billion. Ngokwe-yuan, ukuthunyelwa kwezimpahla kwamanye amazwe kukhuphuke ngamaphesenti angu-14.9, kusukela kumaphesenti angu-7.6.
Isibikezelo semakethe samakhemikhali athile:
1. Isibikezelo: Inani le-methanol ekujikelezeni kwechweba lenyuke kakhulu ngempelasonto edlule. Inani labakhiqizi ezindaweni zokukhiqiza ezisenyakatho liphansi futhi izinga lokusebenza lilonke alishintshi kakhulu. Uma kungekho zici ezinhle ezinkulu, kulindeleke ukuthi i-methanol isazocutshungulwa kakhulu ngokushaqeka kuleli sonto.
2. Isibikezelo: i-toluene, i-xylene yasekhaya iqala phansi, isidingo sisonke sibuthakathaka. Izitokwe zechweba ziyaqhubeka nokwehla. Ukuguquguquka kwentengo kawoyela kunamandla. Kulindeleke kuleli sonto ukuthi imakethe ye-toluene yasekhaya, i-xylene ishaqeke kancane.
3. Isibikezelo: Izinga lokusebenza kwabakhiqizi be-PVC lithuthukisiwe, kodwa i-oda langaphambilini alikaqedwa, futhi inani lezindawo ezitholakala emakethe lincane kakhulu. Enyakatho, ngenxa yokuvikelwa kwemvelo nezinye izizathu, isidingo esingezansi sehle kancane. Indawo yokuthengisa engezansi iphikisana namanani aphezulu kodwa kudingeka nje izinzile. Ekupheleni kwesonto eledlule, ukwehla kwemakethe yemali kuye kwehla, imakethe kulindeleke ukuthi iqhubeke nokuguquguquka okuphezulu kwaleli sonto, futhi kudingeka kuqashelwe ukuthi inkontileka yesikhathi esizayo kaJanuwari isesengozini yokuguquguquka okukhulu.
4. Isibikezelo: Ngesonto eledlule, ukunikezwa kwe-acrylic acid kanye ne-ester kuncane futhi izinto zokusetshenziswa ezihlobene zikhuphuka ngaphansi kwezindaba ezinhle ukuze ziqhubeke nokuqina. Njengamanje, ukunikezwa kwe-spot kusancane, abakhiqizi ngeke banciphise intengo, badinga nje ukulandelela isimo esingezansi. I-acrylic acid kanye ne-ester kulindeleke ukuthi imakethe ye-spot iqhubeke nokusebenza okuqinile kokuqeda kuleli sonto.
5. Isibikezelo: Amanani e-anhydride yama-maleic ehle kakhulu futhi ngokushesha ngesonto eledlule, okuphinda isimo se-roller coaster. Ngenxa yokulindela isidingo esiqinile esiqhubekayo, abakhiqizi be-anhydride yama-maleic banepuleti lokuvala ukuze bandise isenzo. Ukunyuka kulindeleke ukuthi kuqhubeke kuleli sonto.
6, ukuvalwa kwemishini yangaphandle ngenxa yokwehluleka, kanye nokusekelwa kwezindleko okuqinile, imakethe ye-styrene yamukele ukubuya kabusha ekuqaleni kwesonto. Kodwa-ke, amayunithi asekhaya aqala ukukhiqizwa, kanye nesidingo esilandelayo sibuthakathaka, kulinganiselwa ukuthi imakethe ye-styrene izonqunyelwa esikhathini esifushane.
7. Ukuntuleka kokuxhumana phakathi kokunikezwa kanye nesidingo, kulinganiselwa ukuthi imakethe ye-acetone ngeke ibe nendawo enkulu yokwenyuka kwesikhathi esifushane.
8. Kulinganiselwa ukuthi imakethe ye-DOP ingase yehle kakhulu esikhathini esifushane ngenxa yokukhululwa kwezindleko kanye nesidingo esinciphayo.
9, amathuba okuba nethuba uma kungekho sikhuthazo esikhulu esihle, qikelela ukuthi ukwanda kwemakethe ye-phthalic anhydride yesikhashana kunzima kakhulu.
10. Ngokusekelwe esimweni sokuntuleka kokunikezwa kanye nesidingo esibuthakathaka, kulinganiselwa ukuthi imakethe ye-MMA ingase ishintshe ngobubanzi obuncane esikhathini esifushane.
11. Ukusekelwa okuqinile kwezindleko, kodwa ukunikezwa kwasekhaya kulindeleke ukuthi kwande. Kulinganiselwa ukuthi esikhathini esifushane, imakethe ye-phenol ingabhekana kakhulu nokushaqeka.
12, umngcele omuhle, ukushaqeka kwemakethe ye-PTA okuqinile ngesonto eledlule. Kodwa-ke, ngenxa yezisekelo ezibuthakathaka, kulinganiselwa ukuthi imakethe ye-PTA izonqunyelwa esikhathini esifushane.
13, ukwesekwa kwezindleko kunamandla, kodwa indima yokucindezela engezansi ijwayelekile, kulinganiselwa ukuthi imakethe ye-benzene emsulwa esikhathini esifushane noma izoba ukuhlanganiswa okuqinile.
14. Uhlangothi lokuhlinzeka luveza okuthile okuhle, kodwa ukuntuleka kokubambisana okuphumelelayo nesidingo, kulinganiselwa ukuthi imakethe ye-tianjiao izonyakaziswa kakhulu esikhathini esifushane, inake isiqondiso sezici ezingaphandle.
Ngesonto eledlule, imakethe ye-acetic acid yasekhaya iqhubekile nokukhula. Njengamanje, ifektri isivele inciphile ekulethweni, kuhlangene nokuvalwa okungalindelekile kwesitshalo se-BP eNanjing, uhlangothi lokuhlinzeka luqinisiwe kakhulu. Kodwa-ke, ngenxa yokwenyuka okusheshayo kwentengo yemakethe kanye nokumelana okunamandla endaweni engezansi, kulindeleke ukuthi imakethe ingase yehle kuleli sonto uma kuqhathaniswa nesonto eledlule.
16. Imakethe ye-butanone yasekhaya ikhuphuke kakhulu ngesonto eledlule. Ifektri ayinayo ingcindezi yempahla ethengiswayo, futhi isimo sokuphenya esingezansi sizothuthuka, singene emakethe kanye nokuthengwa kwezinto ezihlanganisiwe, okuqhutshwa isimo sokuthenga, kulindeleke ukuthi imakethe ingase ikhuphuke kuleli sonto.
17, ngesonto eledlule, ukushaqeka kwemakethe ye-ethylene glycol yasekhaya kunamandla. Ukuhlanganiswa kokuguquguquka kwamanani kawoyela wamazwe ngamazwe; Njengamanje, ukuqhubeka kwechweba kuya kwelinye kuncane kakhulu; Nakuba amanye amayunithi e-ethylene glycol aqalwa kabusha, kwakusekhona amanye amayunithi alungiswayo futhi encishisiwe, futhi ukwanda kokunikezwa kwakungaphansi kwalokho obekulindelekile. Ukuphela kwe-polyester engezansi kuqala ukugcina ukusebenza okuphezulu nokuzinzile kwesidingo. Kulindeleke ukuthi ukuhlanganiswa kwe-glycol interval yantambama cishe kuzoba namandla.
18, ngesonto eledlule, ukubuyiselwa emuva kokuguquguquka kwemakethe ye-diethylene glycol yasekhaya. Ukuhlanganiswa kokuguquguquka kwentengo kawoyela yamazwe ngamazwe; Njengamanje, umthwalo wokuqala wokufakwa kwasekhaya uhlala uphansi, ukugcwaliswa kabusha kwenani lemikhumbi kuya emikhumbini kunqunyelwe, futhi isimo sezulu esibi sithinta ukwehla okuqhubekayo kwempahla yemikhumbi, ngakho-ke imboni ye-resin engezansi ivame ukuba buthaka. Ukuhlanganiswa kokushaqeka kwemakethe kulindeleke ukuthi kube nokwenzeka kakhulu kuleli sonto.
19. Ukuhlanganiswa kokuguquguquka kwamanani kawoyela wamazwe ngamazwe; Indawo yokukhulisa ikusasa ephezulu; Isitokwe se-Petrochemical sikhuphuke uma kuqhathaniswa nesikhathi esedlule; Ukungqubuzana okuphezulu, kudingeka nje ukuthenga; Izinga lokusebenza kwamabhizinisi asekhaya liphezulu, ingcindezi yokuhlinzeka isekhona. Ngamafuphi, kulindeleke ukuthi amathuba okuhlanganiswa kokuguquguquka kwemakethe ye-PE yasekhaya kuleli sonto.
20. Ukuhlanganiswa kwentengo kawoyela emhlabeni jikelele ngenxa yokuguquguquka; Ikusasa likhuphukile; Izinga lokususwa kwamakhemikhali kaphethiloli lehlile; Isidingo esiphansi sesikhathi sokuphumula sendabuko sizofika, kudingeka nje ukuthatha izimpahla; Ukulahlekelwa kokugcinwa kweyunithi akushintshanga kangako. Ngamafuphi, kulindeleke ukuthi imakethe ye-PP kuleli sonto inciphise amathuba okuhlanganiswa.
