Chiyambi: Pambuyo zoweta koyera MDI msika anapita ku nyumba yosungiramo katundu pa mlingo mkulu mu May, mchitidwe kutsika mu June anapitiriza kugaya anamaliza katundu kufufuza ndi yaiwisi kufufuza, koyera MDI mwa miyezi iwiri destocking, kunsi mtsinje slurry msika wayamba kugula. zolinga, poyambira kufunika, zingathandize MDI yoyera kuti ipite patsogolo?

Mitengo imasinthasintha pang'onopang'ono ndipo ikupitiriza kukumba zinthu zamagulu

Mu 2023, mtengo wa MDI yoyera uli pamalo pomwe pali pafupifupi zaka zitatu, ndi malo ochepa osinthika. Komabe, kuyambira pakati pa mwezi wa April, mtengo wamsika wa MDI yoyera wakwera pang'onopang'ono ndipo ukupitirizabe kusunga mtengo wamtengo wapatali wa chaka, koma mtengowo udakali wochepa kwambiri wa nthawi yomweyi zaka zapitazo. Pamtengo wamtengo uwu, mbali yofunikira imakhala yodziwika bwino, kutsata dongosolo kumapitilizidwa, ndipo kuwerengera kwa zinthu zomwe zamalizidwa koyambirira kumagayidwa. Pakadali pano, zowerengera zamagulu zikupitilizabe kukumba, ndipo kutsika kwapansi kwalowanso mulingo wochepa.

Kuwonongeka kokonza kumakhala kotsika mosalekeza, zomwe ndi zabwino kumbali yopereka msika

Shanghai Lianheng 35+ 240,000 matani/chaka chomangira chakumwa cha mayi chinayamba kukonzedwa motsatizana kuyambira pa Juni 11, zomwe zikukhudza Shanghai Huntsman ndi Shanghai BASF rectification plant, komanso kuwonjezera pakuthandizira kukonza, Ningbo phase I 400,000 matani/chaka chozimitsa chomera, gawo II 800,000 matani/chaka chomera otsika zoipa ntchito, kuwonjezera Fujian chomera zoipa ntchito, kusunga pafupifupi 50% ya katundu. Gawo la 600,000-tani / chaka ku Shanghai lidachepetsedwa chifukwa chazovuta zakutsogolo zopangira zinthu zopangira. Ma seti angapo okonza zida + zovuta zoyipa, katundu wapakhomo wa MDI adangosunga pafupifupi 60%, ndipo kuyambira Marichi, MDI yoyera yonse idapitilirabe kutsika, ndipo kuchuluka kwa magwiridwe antchito mu June ndi Julayi kunangokhala pafupifupi 60%.

Kuthamanga kwapansi kumawonjezeka pang'onopang'ono, ndipo kuwonjezeka kwa slurry ndikowonekera kwambiri

M'mwezi wa Meyi, kuchuluka kwazinthu zakutsika kwamadzi kunali kwakukulu. Pakati pawo, slurry katundu anakhalabe pafupifupi 60%, yekha madzi katundu anakhalabe pa 5-60%, TPU katundu anakhalabe pafupifupi 70%, ndi katundu spandex anakhalabe pa 7-8%. Komabe, ndi mphamvu zochepa zogwiritsira ntchito zowonongeka mu nyumba yosungiramo katundu, kuwonjezeka kwa malamulo osungiramo katundu, malamulo ofooka osowa pakati ndi kumapeto kwa May, kulowa m'magawo a chimbudzi, ndipo kutsika kwa phindu lonse sikuli bwino, slurry yotsika, yokha. madzi, TPU msika wonse malonda mtengo ndi otsika, phindu pang'ono, chifukwa chosowa chidaliro kumtunda, otsika malonda voliyumu lotengeka ndi kukonza katundu, kusintha pang'ono katundu. Koma chiyembekezo cha msika wamtsogolo sichikhala ndi chiyembekezo. Ndipo msika wa spandex chifukwa chakuchulukirachulukira, dziko lotseguka loyipa, kufunikira kwachepa. Pakati pawo, katundu slurry adzakhala pafupifupi 4-5 peresenti, yekha katundu madzi adzakhala anakhalabe pa 5 peresenti, katundu TPU adzakhala anakhalabe pafupifupi 5-6 peresenti, ndi katundu spandex adzakhala anakhalabe pafupifupi 7 peresenti. Komabe, pakati ndi kumapeto kwa June, mitengo ya msika ya slurry, katundu yekha, spandex ndi TPU inalowa m'malo otsika, pambuyo pa chimbudzi cha zinthu mpaka kufika pamtunda wotsika, BDO ndi AA zinayamba motsatizana, chilakolako chogula chinawonjezeka, ndipo msika wotsiriza unakula chifukwa cha mtengo wamtengo wapatali, chilakolako chogula chinatenthedwa, kutsika kwapansi kumawonjezeka pang'onopang'ono, makamaka kufunikira kwa msika wa slurry kutsatira kuwonjezeka koonekeratu.

Poganizira za kutsika komwe kulipo pano, kuchuluka kwa zida zokonzetsera, komanso kukonza kwanthawi yayitali kwa zida zakunja, chipangizo cha Hungary cha Borst Chemical Company MDI (matani 350,000 / chaka) chidayamba kuyimitsa kupanga pa Julayi 18 pakukonza ndikusintha kwaukadaulo ndi kukulitsa. , ndi kuchuluka kwa matani 400,000 / chaka pambuyo pa kusintha kwaukadaulo. Zikuyembekezeka kuti kukonzako kumatenga masiku pafupifupi 80, ndipo mbali yoperekerayo ikhalabe yosungiramo zochepa. Mbali yofunikira kwambiri imayamba pang'onopang'ono, ndipo gawo lowonjezera mphamvu m'munda limatenthedwa, kapena limakhudza mphamvu yokoka ya MDI kwakanthawi kochepa. Komabe, kuchuluka kwa kugwiritsidwa ntchito kwa msika wamagetsi sikwabwino, ndipo chida chowongolera cha MDI chimasunga gawo la mapulani oyendetsa mkati ndi miyezi yomaliza, ndipo malo ogulitsira akuyembekezeka kuwonjezeka pang'ono kapena kukhudza kusinthasintha kwanthawi yayitali komanso kutalika kwa nthawi. , ndikupitiliza kutsata kuchuluka kwa kufunikira ndi kusintha kwa voliyumu munthawi yamtsogolo.
