Imakethe yamakhemikhali yasekhaya yayingaphansi kwengcindezi yokwehla kukawoyela ongahluziwe wamazwe ngamazwe kanye nesidingo esibuthakathaka sasekhaya!

I-South China Index yehla kancane

Iningi lenkomba yokuhlukaniswa liyisicaba

Ngesonto eledlule, imakethe yemikhiqizo yamakhemikhali yasekhaya yehle. Uma sibheka izinhlobo ezingu-20 zokuqapha ukuthengiselana okubanzi, imikhiqizo engu-3 inyusiwe, imikhiqizo engu-8 incishisiwe, kanti engu-9 ayishintshi.

Ngokombono wemakethe yamazwe ngamazwe, imakethe yamafutha angahluziwe yamazwe ngamazwe yehle kakhulu ngesonto eledlule. Phakathi nesonto, isimo senkinga yaseRussia nase-Ukraine kanye ne-Iran kwakunzima ukusiqeda, futhi ukuqina kokunikezwa kwamafutha kwaqhubeka; noma kunjalo, isimo esibuthakathaka kwezomnotho sasilokhu sicindezela ukwenyuka kwamanani kawoyela, imakethe ethintekayo yaqhubeka nokukhula, futhi amanani kawoyela wamazwe ngamazwe ehla kakhulu. Kusukela ngoJanuwari 6, intengo yokuxazululwa kwenkontileka eyinhloko ye-WTI crude oil futures e-United States yayingu-$73.77/ibhareli, eyehlisiwe ngo-$6.49/ibhareli kusukela ngesonto eledlule. Intengo yokuxazululwa kwenkontileka eyinhloko ye-Brent crude oil futures yayiyi-$78.57/ibhareli, eyehlisiwe ngo-$7.34/ibhareli kusukela ngesonto eledlule.

Ngokombono wemakethe yasekhaya, imakethe kawoyela ongahluziwe yayibuthakathaka ngesonto eledlule, futhi kwakunzima ukukhulisa imakethe yamakhemikhali. Eduze noMkhosi WaseNtwasahlobo, amabhizinisi asekhaya amiswe emsebenzini ngokulandelana, futhi isidingo besibuthakathaka sokudonsela imakethe phezulu, kanti imakethe yamakhemikhali ibuthakathaka. Ngokusho kwedatha yokuqapha idatha yokuthengiselana kweGuanghua, inkomba yentengo yemikhiqizo yamakhemikhali yaseNingizimu China yayiphansi ngesonto eledlule, kanti inkomba yentengo yemikhiqizo yamakhemikhali yaseNingizimu China (ebizwa ngokuthi “i-South China Chemical Index”) yayingamaphuzu angu-1096.26, eyehle ngamaphuzu angu-8.31 uma kuqhathaniswa nesonto eledlule, ukwehla ngo-0.75% Essence Phakathi kwezinkomba zokuhlukaniswa ezingu-20, izinkomba ezintathu ze-toluene, ezimbili ezinkulu, kanye ne-TDI zikhuphukile, kanti izinkomba eziyisishiyagalombili zezinkomba eziyisishiyagalombili zezinkomba eziyisishiyagalombili zezinkomba eziyisishiyagalombili ze-aromatics, i-methanol, i-acryl, i-MTBE, i-PP, i-PE, i-formaldehyde, kanye ne-styrene zinciphile, kanti izinkomba ezisele zahlala zizinzile.

Umfanekiso 1: Idatha yokubhekisela ye-South China Chemical Index ngesonto eledlule (isisekelo: 1000). Intengo yokubhekisela icashunwe ngabadayisi.

Umfanekiso 2: Inkomba Yokuthambekela KweNingizimu China kusukela mhla zingama-21 kuJanuwari kuya kuJanuwari 2023 (isisekelo: 1000)

Ingxenye yendlela yokuthambekela kwemakethe yenkomba yokuhlukaniswa

1. I-Methanol

Ngesonto eledlule, imakethe ye-methanol yayibuthakathaka. Njengoba amanani emakethe yamazwe ngamazwe kawoyela ongahluziwe ehla, isimo sengqondo semakethe siba buthaka, ikakhulukazi amabhizinisi amaningi asemaphethelweni athatha iholide kusenesikhathi, isimo sokuthunyelwa kwezindawo zokuthutha asisihle, ingcindezi yemakethe iyonke yehla.

Kusukela ntambama yangomhlaka-6 Januwari, inkomba yentengo ye-methanol eNingizimu yeShayina ivale ngamaphuzu angu-1140.16, yehle ngamaphuzu angu-8.79 noma u-0.76% uma kuqhathaniswa nesonto eledlule.

2. I-SodiumHi-ydroxide

Ngesonto eledlule, imakethe yasekhaya ye-liquid-alkali yayibuthakathaka futhi izinzile. Eduze noMkhosi WaseNtwasahlobo, ukuthandwa kokuthengiselana kwemakethe kuye kwehla, isidingo sokuthenga siyancipha, ukuthunyelwa kwebhizinisi kuhamba kancane, futhi akukho ukwesekwa okuhle okwamanje, futhi imakethe iyonke ibuthakathaka kancane kancane.

Ngesonto eledlule, imakethe ye-alkali yasekhaya yaqhubeka nokusebenza ngokuqhubekayo, kodwa isimo sokuthuthwa kwemakethe saba buthaka uma siqhathaniswa nesikhathi esidlule. Ingcindezi ekuthunyelweni kwamabhizinisi yanda kancane kancane, futhi imakethe yayisebenza okwesikhashana.

Kusukela ngoJanuwari 6, inkomba yentengo ye-pyrine eNingizimu yeShayina yavalwa ngamaphuzu angu-1683.84, okwakufana nesonto eledlule.

3. I-Ethylene Glycol

Ngesonto eledlule, imakethe ye-ethylene glycol yasekhaya yayingasebenzi kahle. Phakathi nesonto, ezinye zezimboni zezindwangu ezinobuthi ziye zayeka iholide, isidingo sinciphile, ukuthunyelwa kwemikhumbi kunciphile, isimo sokulethwa ngokweqile siyaqhubeka, imakethe ye-ethylene glycol yasekhaya inciphile.

Kusukela ngoJanuwari 6, inkomba yentengo ye-glycol eNingizimu yeShayina ivale ngamaphuzu angu-657.14, yehle ngamaphuzu angu-8.16, noma u-1.20%, kusukela esontweni eledlule.

4. I-Styrene

Ngesonto eledlule, imakethe yasekhaya ye-styrene yenza buthaka ukusebenza. Phakathi nesonto, ngaphansi kwethonya lobhubhane kanye nesikhathi sokungasebenzi, ukwakhiwa okuphansi kwehla, isidingo esilandelwayo sasilinganiselwe, futhi isidingo esiqinile sagcinwa, ngakho-ke imakethe kwakunzima ukuyikhulisa, eyayibuthakathaka futhi yehla.

Kusukela ngoJanuwari 6, inkomba yentengo ye-styrene eNingizimu yeShayina ivale ngamaphuzu angu-950.93, yehle ngamaphuzu angu-8.62, noma u-0.90%, kusukela esontweni eledlule.

Ukuhlaziywa kwangemva kwemakethe

Ukukhathazeka kwemakethe ngomnotho kanye namathuba okufunwa kuyaqhubeka, imakethe ayinawo amandla futhi inenzuzo, futhi amanani kawoyela emhlabeni wonke angaphansi kwengcindezi. Ngokombono wasekhaya, njengoba uMkhosi WaseNtwasahlobo usondela, isidingo sokugcina siya ngokuya sihamba kancane, futhi isimo semakethe yamakhemikhali singaphansi kwengcindezi. Kulindeleke ukuthi imakethe yamakhemikhali yasekhaya ingase iqhubeke nokulahlekelwa esikhathini esizayo esiseduze.

1. I-Methanol

Izinga lokusebenza lilonke ledivayisi eyinhloko ye-olefin lithuthukile ekuthuthukisweni kwenzuzo. Kodwa-ke, ngenxa yokuthi indlela ejwayelekile engezansi iseduze noMkhosi WaseNtwasahlobo, ezinye izinkampani ziye zayeka ukusebenza eholidini kusenesikhathi. Isidingo se-methanol sibuthakathaka, futhi ukwesekwa kohlangothi lwesidingo kubuthakathaka. Uma kubhekwa konke, kulindeleke ukuthi imakethe ye-methanol isebenze kancane.

2. I-SodiumHi-ydroxide

Ngokuphathelene ne-alkali ewuketshezi, ngaphambi kweholide loMkhosi WaseNtwasahlobo, amanye amadivayisi noma izindawo zokupaka ezingezansi zizongena eholidini, isidingo kulindeleke ukuthi sehle, futhi ama-oda okuhweba angaphandle abekwe phezulu alethwa futhi aqedwe kancane kancane. Ngaphansi kwethonya lezinto eziningi ezimbi, kulindeleke ukuthi imakethe ye-alkali ewuketshezi ingase yehle.

Ngokuphathelene namaphilisi e-caustic soda, ukuqaphela amasheya angezansi akuphezulu, futhi intengo ephezulu ebekwe phezulu ivimbela intshiseko yokuthenga engezansi ngezinga elithile. Kulindeleke ukuthi imakethe yamaphilisi e-caustic soda ingase ibe nomkhuba obuthakathaka esikhathini esizayo esiseduze.

3. I-Ethylene Glycol

Njengamanje, ukukhiqizwa kwe-polyester okuphansi kanye nokuthengiswa kuyaqhubeka nokuncipha, isidingo se-ethylene glycol sibuthakathaka, ukuntuleka kokusekelwa okuhle kwesidingo, isimo sokwanda ngokweqile siyaqhubeka, kulindeleke ukuthi imakethe yasekhaya yamuva ye-ethylene glycol iqhubeke nokugcina ukushaqeka okuphansi.

4. I-Styrene

Njengoba ingxenye yedivayisi iqala kabusha futhi idivayisi entsha ikhiqizwa, ukuhlinzekwa kwe-styrene kuzohlala kukhuphuka, kodwa ukwehla kungene esigabeni samaholide, isidingo asithuthuki kakhulu, i-styrene noma i-shock ebuthakathaka kulindeleke esikhathini esifushane.
