Isalathisi saseMzantsi China siphantsi, kwaye isalathisi sohlulo sinciphile kakhulu.
Kwiveki ephelileyo, imakethi yemveliso yeekhemikhali yasekhaya iye yehla. Xa sijonga iintlobo ezingama-20 zokubeka esweni iintengiselwano ezibanzi, iimveliso ezi-3 zonyusiwe, iimveliso ezili-11 zincitshisiwe, kwaye ezi-6 azitshintshi.
Ngokwembono yemarike yamazwe ngamazwe, imakethi yeoyile ekrwada yamazwe ngamazwe itshintshile kwiveki ephelileyo. Ngeveki, i-OPEC+ inciphise kakhulu izikhundla zemveliso, kwaye ukunikezelwa kwemveliso kuqinisa imakethi; ukunyuka okanye ukucotha kwenzala yeFed, okwenza kube lula ukuxhalaba koqoqosho kunye namaxabiso eoyile yamazwe ngamazwe anyuke. Ukusukela ngoDisemba 2, ixabiso lokuhlawula isivumelwano esiphambili se-WTI crude oil futures eMelika yayiyi-$79.98/barrel, eyayiyi-$3.7 US dollars ngebharel ukusuka kwiveki ephelileyo. Ixabiso lemakethi yeoyile ekrwada yeBrent crude oil futures lilungisiwe, kwaye ixabiso lokuhlawula isivumelwano esiphambili yi-US $85.57/barrel, ephakanyiswe yi-$1.94/barrel xa kuthelekiswa neveki ephelileyo.
Ngokwembono yemarike yasekhaya, imakethi yeoyile eluhlaza ibilawulwa kakhulu kwiveki ephelileyo. Imisebenzi iyonke yezoqoqosho yemisebenzi yezoqoqosho yasekhaya iye yehla, impembelelo yesiqhelo yexesha elingaphandle kwexesha yayingaphezulu, imfuno yayincinci, kwaye ukusebenza kwemarike yamakhemikhali bekubuthathaka. Ngokwedatha yokujonga ukuthengiselana kwamakhemikhali ngokubanzi, isalathisi samaxabiso seeMveliso zeKhemikhali zaseMzantsi China besisezantsi kwiveki ephelileyo, kwaye isalathisi samaxabiso seeMveliso zeKhemikhali zaseMzantsi China (eza kubizwa ngokuba yi "South China Chemical Index") kwiveki yayingamanqaku ayi-1171.66, awe ngamanqaku angama-48.64 xa kuthelekiswa neveki ephelileyo, ukwehla kwe-3.99% Essence Phakathi kwee-indexes zodidi ezingama-20, ii-indexes ezintathu ze-acryllene, PP, kunye ne-styrene rose, ezixutywe ne-aromatics, toluene, methanol, PTA, pure benzene, MTBE, BOPP, PE, diopine, TDI, sulfuric acid zehlile, kwaye ezinye ii-indexes zahlala zizinzile.
Umfanekiso 1: I-South China Chemical Index yeveki ephelileyo idatha yesalathiso (isiseko: 1000), ixabiso lesalathiso licatshulwe ngabarhwebi
Inxalenye yendlela yokuthengisa i-index yohluhlu
1. I-Methanol
Kwiveki ephelileyo, imakethi ye-methanol ibibuthathaka. Ngeveki, ukufakelwa komsebenzi wokulungisa ngaphambi kokuba kumiswe kwaqaliswa kwakhona, kwaye ukunikezelwa kwemveliso kwanda; imfuno yesiqhelo esezantsi kwakunzima ukunyuka ngenxa yexesha lokuphumla kunye nobhubhane. Phantsi kokucinezelwa kokunikezelwa kwemveliso okuncinci, iimeko zemakethi zizonke zaqhubeka nokuhla.
Ukususela emva kwemini ngomhla wesi-2 kweyoMnga, isalathisi sexabiso le-methanol eMzantsi China sivale kuma-1223.64 amanqaku, sehle ngama-32.95 amanqaku kwiveki ephelileyo, ukwehla kwe-2.62%.
2. Isoda ekrakra
Kwiveki ephelileyo, imakethi yasekhaya ye-alkali yolwelo incitshisiwe. Okwangoku, uxinzelelo lwempahla yenkampani alukho mkhulu, kwaye imeko yokuthunyelwa kwempahla iyamkeleka. Amaxabiso e-chlorine yolwelo aqhubekile nokuhla. Ngoncedo lwenkxaso yeendleko, ixabiso lemakethi linyusiwe.
Kwiveki ephelileyo, imakethi ye-alkali yetshiphusi yasekhaya izinzisile ukusebenza kwayo. Imo yemarike igcine inqanaba lokuqala, imeko yenkampani izinzile ngokwexabiso, kwaye imakethi ye-alkali yepiyano iyonke igcina umkhwa wozinzo.
Ukusukela ngomhla wesi-2 kweyoMnga, isalathisi samaxabiso okurosa isoda eMzantsi China sivale ngamanqaku ayi-1711.71, ukunyuka kwamanqaku ayi-11.29 kwiveki ephelileyo, ukunyuka kwe-0.66%.
3. I-ethylene glycol
Kwiveki ephelileyo, imakethi ye-ethylene glycol yasekhaya iqhubekile nokushukuma. Kutshanje, iyunithi ye-ethylene glycol ibisoloko ivuliwe, isiqalo sotshintsho oluncinci, kodwa uxinzelelo lwecala lokubonelela lusekhona; Imfuno esezantsi ayiphucukanga kakhulu, imakethi ye-ethylene glycol yasekhaya ukuze igcine ukushukuma okuphantsi.
Ukusukela nge-2 kaDisemba, i-index yexabiso kwi-diol yaseMzantsi China yayivaliwe ngamanqaku angama-665.31, ukwehla ngamanqaku angama-8.16 kwiveki ephelileyo, ukwehla kwe-1.21%.
4. Isitayile
Kwiveki ephelileyo, iziko lemarike yasekhaya ye-styrene liye lenyuka. Ngeveki, izinga lokusebenza kwesixhobo somzi-mveliso liye lehla ukuze kuncitshiswe uluhlu oluncinci lonikezelo; imfuno esezantsi ibinamandla, kwaye imakethi ixhaswe kakuhle. Unikezelo kunye nemfuno iyonke ibikwibhalansi eqinileyo, kwaye ixabiso lemarike lenyuka.
Ukusukela nge-2 kaDisemba, ixabiso le-styrene eMzantsi China livale kuma-953.80 points, ukunyuka kwama-22.98 points kwiveki ephelileyo, ukunyuka kwama-2.47%.
Uhlalutyo lwemarike yexesha elizayo
Amaxabiso eoyile kusenokwenzeka ukuba ahlale engaguquki njengoko uloyiko lokudodobala koqoqosho kunye nokuxhalaba malunga nombono wemfuno kuqhubeka nokulawula imarike ngaphandle kwenkqubela phambili ekunciphiseni imveliso ye-OPEC+. Ngokwembono yasekhaya, uqoqosho lwasekhaya kunzima ukuluphucula kwixesha elifutshane, kwaye ukubuyiselwa kwemfuno yokugqibela kuhamba kancinci. Kulindeleke ukuba imakethi yasekhaya yeekhemikhali isenokuba buthathaka kwixesha elizayo.
1. I-Methanol
Kwixesha lasebusika, umbane wegesi yendalo ngowona uphambili, kwaye ezinye izixhobo ze-methanol zinomsebenzi ongalunganga okanye ongasebenzi kakuhle. Nangona kunjalo, uluhlu lwangoku lomenzi luphezulu, kwaye kulindeleke ukuba umbane wemarike ube mkhulu. Ukwehla kwemfuno ephantsi kunzima ukutshintsha. Kulindeleke ukuba imakethi ye-methanol ibe buthathaka kakhulu.
2. Isoda ekrakra
Ngokuphathelele i-liquid caustic soda, ngokwembono yemeko yemarike yangoku, uxinzelelo lwempahla yenkampani ephambili alukho mkhulu, kodwa ngenxa yokuba ubhubhane uphindaphindeka, ukuthuthwa kwezinye iindawo kusancinci, kwaye inkxaso yesiphelo ayinamandla. Kulindeleke ukuba imarike ye-liquid -alkali izinzise ukusebenza kwixesha elizayo.
Ngokuphathelele ii-caustic soda flakes, uluhlu lwamashishini akhoyo luphantsi, kodwa imfuno ephantsi isephakathi, ixabiso lemarike kunzima ukulinyusa, kwaye indlela inkampani ecinga ngayo ngexabiso elizinzileyo icacile. Kulindeleke ukuba imakethi ye-lattice ingazinza kungekudala.
3. I-ethylene glycol
Okwangoku, imfuno yemarike ye-ethylene glycol ayiphucukanga, ukuqokelelwa kwezinto ezikhoyo, kunye nemvakalelo yemarike ayinanto. Kulindeleke ukuba imakethi ye-ethylene glycol yasekhaya iqhubeke nokusebenza kancinci kwixesha elizayo.
4. Isitayile
Nangona imfuno yangoku inyukile, ixesha elifutshane elisezantsi lilumkile, imfuno iyanda okanye iyancitshiswa, kwaye ukubuya kwemarike kuyancitshiswa. Ukuba akukho nkxaso yeendaba ezilungileyo, kulindeleke ukuba i-styrene inyuke kwaye yehle kwixesha elifutshane.
