Kuyambira February, zoweta polymerization diphenyl methane diisocyanate (MDI) msika kuchotsera Yin pansi, koma mitengo zopangira ananyamuka mocheperapo, monga February 20 mu Shandong dera aniline ananyamuka 1000 yuan (tani mtengo, chimodzimodzi pansipa)."Kuthandizira kutha kwamitengo komwe kukufunika kutsika pang'onopang'ono kuyambiranso, kapena kuthamangitsa msika wa MDI pamavuto, ndikutsegula msika."Anthu angapo m'makampani apanga kafukufuku ndi chiweruzo chomwe chili pamwambapa.
Thandizo lotsika mtengo
Aniline aniline amawerengera 75% ya mtengo wa MDI.Posachedwapa, mtengo wa aniline ukukwera, ndipo thandizo la mtengo wa MDI limalimbikitsidwa.
Mpaka pa February 21, mtengo wamsika wa North China aniline unali 12,200 yuan, ukukwera ndi 1950 yuan poyerekeza ndi January 28, kuwonjezeka kwa 19.12%;Kuyambira pa February 17, kukwera ma yuan 1200, kapena 10.96%.
"Kukwera kwakukulu kwa msika wa aniline kumayamba chifukwa cha kuchuluka kwa maoda apakati komanso otsika.Kufunika kwa aniline kwawonjezeka, ndipo magawo angapo opanga adzatsekedwa kuti asamalidwe, kudalira msika kukulirakulira, opanga akuchepetsa mwachangu, ndipo mtengo wa aniline ukukwera kwambiri. ”Shandong Kenli Petrochemical Group wamkulu wa injiniya Wang Quanping adati.
Pakalipano, Nanhua yayimitsa chipangizo cha aniline cha 100,000 / chaka;Chongqing BASF matani 300,000 / chaka choyimitsira magalimoto, akuyembekezeka kutha mwezi wa 1;Ningbo Wanhua 720,000 matani/chaka chipangizo 50% katundu ntchito.
Kuchokera kumtunda kwa aniline, msika wapakhomo wa benzene umakhala wodabwitsa.East China kunsi kwatsiku kukhazikitsidwa kwamayendedwe operekera, kuwerengera kumadoko kudatsika pang'ono.Msika wa benzene ku United States unakwera, mtengo wakunja unakwera, mtengo wapakhomo wa benzene yoyera "concave", yemwe ali ndi masana ambiri.
"Pamaso pa mtengo aniline sanawuke, pafupifupi phindu la zoweta polymerization MDI fakitale anali za 3273 yuan.Kuchuluka kwa zinthu zopangira sikungathetseretu phindu la polymerization MDI, kukulitsa chidwi cha opanga kupanga mitengo. ”Wang Quanping adanena kuti pamsika wamadzulo, kupezeka kwa aniline mwachiwonekere kumachepetsedwa, ndipo zowerengerazo zikhoza kugwera pamunsi.Zikuyembekezeka kuti mtengo wa aniline upitilira kukwera kwakanthawi kochepa, ndikupanga chithandizo chamsika wa polymerized MDI pamaso pa mtengo.
Kufuna stepwise kukonza
Monga msika wa polymeric MDI wakumunsi wa polyether wapita patsogolo pang'onopang'ono posachedwa.Moyendetsedwa ndi propylene oxide ngati zopangira, msika wa polyether umatsegula njira yokoka.Pafupifupi mwezi wa 1, mtengo wa polyether unakwera pang'ono, pakati pa mphamvu yokoka, Chikondwerero cha Spring chakwera 800 yuan.
Kuchokera kumbali yothandizira, katundu wa polyether ndi wokwanira, koma gwero lalikulu la katundu kuti likhale lolimba.Mafakitole akulu kumpoto ndi kumwera ali okonzeka kuthandizira msika, ndipo malo ambiri opangira ma polyether akadali ochepa ndi propylene oxide.Kuphatikiza apo, opanga ali ndi zida zina, ndipo pambuyo pa Chikondwerero cha Spring, msika wa propylene oxide ukukwera kwambiri, ndipo mtengo wazinthu zomalizidwa siwotsika.Akuti kufunitsitsa konyamula katundu ndikofala kwambiri posachedwapa.
"Posachedwapa, kuitanitsa katundu kukuyembekezeka kuonjezera, koma kuchuluka kwa polyether yofewa ndi yocheperako, fakitale yayikulu yapakhomo imamatira kumalingaliro amzindawu."Shandong Institute of industry and information Technology Professors-level senior engineer Pan Jinsong said.
Malinga ndi zomwe zimafunidwa, dongosolo la masiponji amkati amalonda amkati ndi okhazikika, ndipo kugwiritsidwa ntchito kwakukulu kwazinthu zamabizinesi opanga kudzachitika mu Marichi.M'mwezi wa Marichi, chiwonetsero cha mipando chidzachitika, kapena chidzabweretsa zabwino pamsika wazinthu zopangira.Dongosolo la mabizinesi otumiza siponji nthawi zambiri.Ndi Mwezi Wamembala wa Amazon mu Julayi.Zikuyembekezeka kuti izikhala ndi gawo lotsogola m'mabizinesi amtundu wa siponji pambuyo pa Epulo.
Kuchokera kuzinthu zopangira, zokongoletsera zatsopano za oxide ya oxide kumapeto kwa February ndi petrochemical ya satellite yokha, ndi ziyembekezo za chipangizo cha Ida kapena kuyambiranso kuyambiranso.Zida zotsalira zilibe kuwonjezeka kwakukulu pakali pano.Ndi kuyimitsidwa kwa gawo loyamba la Zhenhai Refining ndi Chemical, kupezeka kwa msika sikuli kokwera, ndipo kuthandizira kwamtengo kumakwera.Zikuyembekezeka kuti mitengo ya oxide propyne imakonda kukwera komanso yovuta kutsika, ndipo imathandizirabe msika wa polyether.
Pazonse, pali zizindikiro za kufunikira komaliza, zomwe zipangitsa kuti msika wa MDI ukwere.
Kuchepa komwe kumayembekezereka
Pakali pano, kutsika kwa msika wapakhomo wa MDI kwatsika, ndipo mtengo woperekedwa nthawi zambiri ndi 15,500 ~ 15,800 yuan, ndipo mtengo wamtengo wapatali wa katundu wochokera kunja (MR200, M200) ndi 15,300 ~ 15,600 yuan.
"Pakali pano, mtengo wa aggregation MDI akadali pa mlingo wochepa pafupifupi zaka zitatu. Pachiyembekezo cha wokometsedwa miliri mfundo zopewera ndi kulamulira ndi kuyembekezera kusintha kwachuma, converged MDI msika pang'onopang'ono kukwera masitepe.Ogulitsa amasinthanitsa nthawi kuti apeze malo ndipo pang'onopang'ono amapitilira malamulo amsika malinga ndi kuchuluka kwa anthu omwe amagula pamapeto pake. ”Pan Jinsong adatero.
Kuchokera kumbali yoperekera, zoperekera ndizochepa, zopereka za MDI zophatikizika zimakhalabe zapamwamba, malingaliro amsika ndi osamala.Ndi kukonza kwa ogulitsa ndi kutumiza pang'onopang'ono, dongosolo lazofuna limakhazikika kwambiri, malo ogula akuwotha, ndipo pakati pa mphamvu yokoka ya gawo la MDI yophatikizira ikukwera.
Pankhani ya zida, zida za MDI zokwana matani 400,000 / chaka ku Chongqing zidalowa m'malo okonza pa February 5, zomwe zikuyembekezeka kukhala pakati pa Marichi.Zida za Ningbo 800,000 / chaka zidzayimitsidwa kuti zikonzedwe kuyambira pa February 13, zomwe zimakhala pafupifupi masiku 30.Kupanga kophatikiza kwa MDI kukuyembekezeka kukhala pafupifupi matani 152,000 mu February, kutsika ndi matani 23,300 kuchokera mwezi watha.
Mwachidule, kuthandizira kwamphamvu kwamitengo ya MDI yophatikizika, kuchepa kwa msika komwe kukuyembekezeka, komanso kuyambiranso kwapang'onopang'ono kwa kutsika kwa mitsinje, mphamvu zitatu zophatikizika zitha kuthandiza msika wa MDI kuchotsa kusakhazikika komanso kukwera kwamphamvu.
