Sabata yatha, msika wamankhwala am'nyumba udapitilirabe kutsika, ndikutsika konseko kukukulirakulira poyerekeza ndi sabata yapitayi.Kuwunikidwa kwa msika wazinthu zina zazing'ono
1. Methanol
Sabata yatha, msika wa methanol udalimbikitsa kutsika kwake.Kuyambira sabata yatha, msika wa malasha ukupitirizabe kuchepa, chithandizo chamtengo wapatali chagwa, ndipo msika wa methanol uli pampanipani ndipo kuchepa kwawonjezeka.Kuphatikiza apo, kuyambikanso kwa zida zokonzetsera koyambirira kwadzetsa kuchuluka kwa zinthu, zomwe zidapangitsa kuti msika ukhale wolimba kwambiri komanso kukulitsa kutsika kwa msika.Ngakhale pali kufunikira kwakukulu kwa kuwonjezeredwa pamsika pakatha masiku angapo akutsika, kufunikira kwa msika wonse kumakhalabe kofooka, makamaka popeza misika yapansi panthaka imalowa munyengo yanyengo, zomwe zimapangitsa kuti zikhale zovuta kuchepetsa msika waulesi wa methanol.
Pofika masana a Meyi 26, index yamtengo wa methanol ku South China idatsekedwa pa 933.66, kutsika ndi 7.61% kuyambira Lachisanu lapitali (Meyi 19).

Mlungu watha, zoweta madzi zamchere msika poyamba ananyamuka kenako anagwa.Kumayambiriro kwa sabata, kulimbikitsidwa ndi kusamalira zomera zamchere za chlorine ku North ndi East China, kufunikira kwa katundu kumapeto kwa mwezi, ndi mtengo wotsika wa chlorine wamadzimadzi, malingaliro a msika akuyenda bwino, ndi msika waukulu wa alkali yamadzimadzi yowonjezera;Komabe, nthawi zabwino sizinatenge nthawi yayitali, ndipo panalibe kusintha kwakukulu pakufunidwa kwapansi.Msika wonse wa msika unali wochepa ndipo msika watsika.
Sabata yatha, msika wam'nyumba wamchere wa alkali udakwera kwambiri.Chifukwa chakutsika kwa mtengo wamsika koyambirira, kutsika kwatsika kosalekeza kwalimbikitsa osewera ena otsika kuti awonjezerenso, ndipo kutumiza kwa opanga kwayenda bwino, motero kulimbikitsa msika wa flake caustic soda.Komabe, ndi kukwera kwamitengo ya msika, kufunikira kwa msika kumakakamizikanso, ndipo msika waukulu ukupitirizabe kukwera mofooka.
Pofika pa Meyi 26, South China caustic soda index index idatsekedwa pa 1175
02 mfundo, kutsika ndi 0.09% kuchokera Lachisanu lapitalo (Meyi 19th).
3. Ethylene glycol
Sabata yatha, kuchepa kwa msika wapakhomo wa ethylene glycol kudakwera.Ndi kuchuluka kwa magwiridwe antchito a msika wa ethylene glycol komanso kuchuluka kwa zida zamadoko, kuchuluka kwazinthu zonse kwakula kwambiri, ndipo malingaliro amsika akukula kwambiri.Kuphatikiza apo, kuchita mwaulesi kwazinthu sabata yatha kwadzetsanso kutsika kwa msika wa ethylene glycol.
Kuyambira pa May 26, chiwerengero cha ethylene glycol ku South China chinatsekedwa pa 685.71 mfundo, kuchepa kwa 3.45% poyerekeza ndi Lachisanu lapitalo (May 19th).
4. Sitima
Sabata yatha, msika wapakhomo wa styrene udapitilira kuchepa.Kumayambiriro kwa sabata, ngakhale kuti mafuta amtundu wapadziko lonse adawonjezereka, panalibe chiyembekezo champhamvu pamsika weniweni, ndipo msika wa styrene unapitirizabe kuchepa pansi pa kukakamizidwa.Makamaka, msika uli ndi malingaliro amphamvu opita kumsika wamankhwala am'nyumba, zomwe zapangitsa kuti kuchulukitsitsa kotumizira pamsika wa styrene, ndipo msika waukulu wapitilirabe kutsika.
Kuyambira pa May 26, chiwerengero cha mtengo wa styrene ku South China chinatsekedwa pa mfundo za 893.67, kuchepa kwa 2.08% poyerekeza ndi Lachisanu lapitalo (May 19th).

Aftermarket kusanthula
Ngakhale kuwerengera kwa US kudatsika kwambiri sabata ino, chifukwa chakufunika kwakukulu ku US m'chilimwe, komanso kuchepetsa kupanga kwa OPEC + kunabweretsanso phindu, vuto la ngongole ku US silinathe.Kuphatikiza apo, ziyembekezo zakugwa kwachuma ku Europe ndi America zikadalipo, zomwe zitha kusokoneza momwe msika wapadziko lonse wamafuta osakanikira umagwirira ntchito.Zikuyembekezeka kuti padzakhalabe kutsika kwamphamvu pamsika wamafuta wapadziko lonse lapansi.Malinga ndi momwe dziko likuyendera, msika wamafuta wapadziko lonse lapansi ukukulirakulira, kuthandizira kwamitengo yochepa, ndipo msika wamankhwala wapakhomo utha kukhala wofooka komanso wosakhazikika.Kuphatikiza apo, mankhwala ena otsika m'mphepete mwa nyanja alowa m'nyengo yachilimwe, ndipo kufunikira kwa mankhwala kumakadali kofooka.Chifukwa chake, zikuyembekezeredwa kuti malo obwereranso pamsika wamankhwala apanyumba ndi ochepa.
1. Methanol
Posachedwapa, opanga monga Xinjiang Xinye akonzekera kukonza, koma mayunitsi angapo ochokera ku China National Offshore Chemical Corporation, Shaanxi, ndi Inner Mongolia ali ndi mapulani oti ayambitsenso, zomwe zimapangitsa kuti pakhale chakudya chokwanira kuchokera ku China, zomwe sizikugwirizana ndi msika wa methanol. .Pakufunidwa, chidwi chofuna kuti mayunitsi akulu a olefin ayambe kumanga sichapamwamba ndipo chimakhala chokhazikika.Kuphatikiza apo, kufunikira kwa MTBE, formaldehyde, ndi zinthu zina kwakwera pang'ono, koma kuwongolera kwazinthu zonse kukuchedwa.Ponseponse, zikuyembekezeka kuti msika wa methanol ukhalabe wofooka komanso wosasunthika ngakhale kuli kokwanira komanso kufunikira kovutira kutsatira.

Pankhani ya alkali yamadzimadzi, pali chiwopsezo chokwera pamsika wamsika wamchere wamchere.Chifukwa cha zabwino zokonza ndi opanga ena mdera la Jiangsu, msika wa alkali wamadzimadzi wawonetsa kukwera.Komabe, osewera otsika amakhala ndi chidwi chochepa cholandira katundu, zomwe zingafooketse thandizo lawo pamsika wamadzimadzi a alkali ndikuchepetsa kukwera kwamitengo yamisika yayikulu.
Pankhani ya flake alkali, msika wam'nyumba wa alkali uli ndi mphamvu zochepa zokwera.Opanga ena amawonetsabe zizindikiro zokweza mitengo yawo yotumizira, koma zomwe zikuchitika zitha kusokonezedwa ndi kukwera kwa msika.Choncho, zoletsa pa msika zinthu.
3. Ethylene glycol
Zikuyembekezeka kuti kufooka kwa msika wa ethylene glycol kupitilirabe.Kukwera kwa msika wapadziko lonse wamafuta amafuta ndikochepa, ndipo kuthandizira kwamitengo kumakhala kochepa.Kumbali yoperekera, ndikuyambiranso kwa zida zokonzetsera koyambirira, pali ziyembekezo zakuwonjezeka kwa msika, womwe umakhala wokhazikika pamsika wa ethylene glycol.Pakufunidwa, kupanga poliyesitala kukuyenda bwino, koma mayendedwe akukula pang'onopang'ono ndipo msika wonse ulibe mphamvu.
