I-South China Index iyancipha
Uninzi lwesalathisi sohlulo asiguquki
Kwiveki ephelileyo, imakethi yemveliso yeekhemikhali yasekhaya iye yehla. Xa sijonga iintlobo ezingama-20 zokubeka esweni iintengiselwano ezibanzi, iimveliso ezi-3 zonyusiwe, iimveliso ezi-8 zincitshisiwe, kwaye ezi-9 azinazo zonke iimveliso.
Ngokwembono yemarike yamazwe ngamazwe, imakethi yeoyile ekrwada yehlabathi ihlile kakhulu kwiveki ephelileyo. Ngeveki, imeko yengxaki yeRashiya neUkraine kunye ne-Iran yayinzima ukuyiphelisa, kwaye ukuqina kokunikezelwa kwempahla kwaqhubeka; nangona kunjalo, imeko ebuthathaka kwezoqoqosho yayisoloko icinezela ukunyuka kwamaxabiso eoyile, imakethi echaphazelekayo yaqhubeka inyuka, kwaye amaxabiso eoyile yamazwe ngamazwe ehla kakhulu. Ukusukela nge-6 kaJanuwari, ixabiso lokuhlawula isivumelwano esiphambili se-WTI crude oil futures eMelika yayiyi-$73.77/barrel, eyancitshiswa yi-$6.49/barrel kwiveki ephelileyo. Ixabiso lokuhlawula isivumelwano esiphambili se-Brent crude oil futures yayiyi-$78.57/barrel, eyancitshiswa yi-$7.34/barrel kwiveki ephelileyo.
Ngokwembono yemarike yasekhaya, imakethi yeoyile eluhlaza ibibuthathaka kwiveki ephelileyo, kwaye bekunzima ukukhulisa imakethi yeekhemikhali. Kufuphi neSpring Festival, amashishini asekhaya amiswe emsebenzini emva komnye, kwaye imfuno ibibuthathaka yokutsala imakethi inyuke, kwaye imakethi yeekhemikhali ibuthathaka. Ngokwedatha yokujonga idatha yentengiselwano yaseGuanghua, isalathisi samaxabiso eeMveliso zeeKhemikhali zaseMzantsi China besisezantsi kwiveki ephelileyo, kwaye isalathisi samaxabiso eeMveliso zeeKhemikhali zaseMzantsi China (eza kubizwa ngokuba yi "South China Chemical Index") yayingamanqaku ayi-1096.26, ehle ngamanqaku ayi-8.31 xa kuthelekiswa neveki ephelileyo, ukwehla kwe-0.75% Essence Phakathi kwee-indexes zodidi ezingama-20, ii-indexes ezi-3 ze-toluene, ezimbini ezinkulu, kunye ne-TDI zinyukile, kwaye ii-indexes ezisibhozo zee-indexes ezisibhozo zee-indexes ezisibhozo ze-aromatics, i-methanol, i-acryl, i-MTBE, i-PP, i-PE, i-formaldehyde, kunye ne-styrene zinciphile, ngelixa ii-indexes ezisele zihlala zizinzile.
Umfanekiso 1: Idatha yesalathiso seSouth China Chemical Index kwiveki ephelileyo (isiseko: 1000). Ixabiso lesalathiso licatshulwe ngabarhwebi.
Umfanekiso 2: I-Trend of South China Index ukusuka nge-21 kaJanuwari ukuya kuJanuwari 2023 (isiseko: 1000)
Inxalenye yendlela yokuthengisa i-index yohluhlu
1. I-Methanol
Kwiveki ephelileyo, imakethi ye-methanol ibibuthathaka. Njengoko amaxabiso eemakethi zeoyile ekrwada zamazwe ngamazwe ehla, indlela yokucinga yemakethi iba buthathaka, ingakumbi amashishini amaninzi asezantsi aphumla kwangaphambili, imeko yokuthunyelwa kweendawo zokuthutha ayilunganga, uxinzelelo lwemakethi ngokubanzi luyancipha.
Ukususela emva kwemini kaJanuwari 6, isalathisi sexabiso le-methanol eMzantsi China sivale kuma-1140.16 amanqaku, sehle ngama-8.79 amanqaku okanye i-0.76% xa kuthelekiswa neveki ephelileyo.
2. IsodiyamHi-ydroxide
Kwiveki ephelileyo, imakethi yasekhaya ye-alkali yolwelo ibibuthathaka kwaye izinzile. Kufuphi neMnyhadala weNtwasahlobo, ukuthandwa kweentengiselwano zemakethi kuye kwehla, imfuno yokuthenga iyabuthathaka, ukuthunyelwa kwempahla kumashishini kuhamba kancinci, kwaye akukho nkxaso ilungileyo okwangoku, kwaye imakethi iyonke ibuthathaka kancinci kancinci.
Kwiveki ephelileyo, imakethi ye-alkali yasekhaya iqhubekile nokusebenza ngokuzinzileyo, kodwa umoya wokuthutha imakethi ube buthathaka xa uthelekiswa nexesha elidlulileyo. Uxinzelelo lokuthunyelwa kwamashishini luye lwanda kancinci kancinci, kwaye imakethi ibisebenza okwethutyana.
Ukusukela nge-6 kaJanuwari, i-index yexabiso le-pyrine eMzantsi China ivale ngamanqaku ayi-1683.84, nto leyo yayifana neyeveki ephelileyo.
3. I-Ethylene Glycol
Kwiveki ephelileyo, imakethi ye-ethylene glycol yasekhaya ayisebenzi kakuhle. Phakathi evekini, ezinye iifektri zelaphu ezinetyhefu ziye zayeka iholide, imfuno iyancipha, ukuthunyelwa kweenqanawa kunciphile, imeko yokuthengiswa ngokugqithisileyo iyaqhubeka, imakethi ye-ethylene glycol yasekhaya ibuthathaka.
Ukususela nge-6 kaJanuwari, i-index yexabiso le-glycol eMzantsi China ivale kuma-657.14 points, ihle ngama-8.16 points, okanye i-1.20%, ukusuka kwiveki ephelileyo.
4. I-Styrene
Kwiveki ephelileyo, imakethi yasekhaya ye-styrene ibuthathaka ekusebenzeni. Ngeli veki, phantsi kwempembelelo yobhubhane kunye nexesha elingekhoyo, ulwakhiwo olusezantsi luye lwanehla, imfuno elandelwayo yayincinci, kwaye imfuno eqinileyo yagcinwa, ngoko ke imakethi yayinzima ukuyinyusa, eyayibuthathaka kwaye isezantsi.
Ukususela nge-6 kaJanuwari, i-styrene price index eMzantsi China ivale kuma-950.93 points, ihle ngama-8.62 points, okanye i-0.90%, ukusuka kwiveki ephelileyo.
Uhlalutyo lwasemva kwemarike
Iinkxalabo zemarike malunga noqoqosho kunye namathuba emfuno ziyaqhubeka, imarike ayinawo amandla kwaye ilungile, kwaye amaxabiso eoyile yamazwe ngamazwe aphantsi koxinzelelo. Ngokwembono yasekhaya, njengoko uMnyhadala weNtwasahlobo usondela, imfuno yokugqibela iya isiba mandundu, kwaye imeko yemarike yeekhemikhali iphantsi koxinzelelo. Kulindeleke ukuba imarike yeekhemikhali yasekhaya iqhubeke nokungafezeki kwixesha elizayo.
1. I-Methanol
Izinga lokusebenza lilonke lesixhobo esiphambili se-olefin liphucukile ekuphuculeni inzuzo. Nangona kunjalo, ngenxa yokuba indlela eqhelekileyo yokwehla ikufutshane noMnyhadala weNtwasahlobo, ezinye iinkampani ziye zayeka ukusebenza kwiiholide kwangaphambili. Imfuno ye-methanol ibuthathaka, kwaye inkxaso yecala lemfuno ibuthathaka. Xa zizonke, kulindeleke ukuba imakethi ye-methanol isebenze kancinci.
2. IsodiyamHi-ydroxide
Ngokuphathelele i-alkali engamanzi, ngaphambi kweholide yeSpring Festival, ezinye izixhobo okanye iindawo zokupaka ziya kungena kwiholide, kulindeleke ukuba imfuno yehle, kwaye ii-odolo zorhwebo lwangaphandle ezibekwe ngaphezulu ziyahanjiswa kwaye zigqitywe kancinci kancinci. Phantsi kwempembelelo yee-negative ezininzi, kulindeleke ukuba imakethi ye-alkali engamanzi ihle.
Ngokuphathelele iipilisi ze-caustic soda, ulwazi lwesitokhwe esisezantsi aluphezulu, kwaye ixabiso eliphezulu elibekwe phezulu lithintela umdla wokuthenga osezantsi ukuya kwinqanaba elithile. Kulindeleke ukuba imakethi yeepilisi ze-caustic soda isenokuba nomkhwa obuthathaka kwixesha elizayo.
3. I-Ethylene Glycol
Okwangoku, imveliso ye-polyester esezantsi kunye neentengiso ziyaqhubeka nokuthotywa, imfuno ye-ethylene glycol ibuthathaka, ukungabikho kwenkxaso elungileyo kwimfuno, imeko yokubonelela ngokugqithisileyo iyaqhubeka, kulindeleke ukuba imarike ye-ethylene glycol yasekhaya yakutshanje okanye iqhubeke nokugcina ukukhwankqiswa okuphantsi.
4. I-Styrene
Xa inxalenye yesixhobo iqala ukuveliswa kwakhona kwaye isixhobo esitsha siqala ukuveliswa, ukunikezelwa kwe-styrene kuya kuhlala kusanda, kodwa ukwehla kungene kwisigaba seholide, imfuno ayiphucukanga kakhulu, kulindeleke ukuba i-styrene okanye i-weak shock ivele kwixesha elifutshane.
