Kuwongolera mu theka lachiwiri la chaka kwayamba, ndipo chiwerengero chachikulu cha zowonjezera chimayikidwa mu July-August, ndipo zopangira zowonongeka zayamba kuchepa.Kuphatikiza apo, ena opanga zida zazikulu adalengeza zamphamvu majeure, zomwe zidakulitsa kuchuluka kwa msika.

Zasiya!Kukonza kwa Wanhua, BASF, Covestro ndi zina zamphamvu majeure!

Wanhua Chemical idapereka chilengezo choyimitsa kupanga pa Julayi 6, ndikulengeza kuti iyamba kupanga ndi kukonza pa Julayi 10, ndipo kukonza kuyenera kukhala masiku 25.

Kuphatikiza apo, pali zida zambiri zamtundu wa MDI zomwe zagwa mumphamvu majeure ndikuzimitsa kuti zikonze.

▶ Covestro: pa Julayi 2 adalengeza mphamvu majeure ya 420,000 matani / chaka chipangizo cha MDI ku Germany, matani 330,000 / chaka MDI ku United States ndi zinthu zina;

▶Huntsman: Idaunikiridwa ndikukonzedwa kambirimbiri kuyambira Marichi mpaka Juni, ndipo pakadali pano ambiri oyikapo kunyumba ndi kunja adayimitsidwa;

▶ Zida za MDI za BASF, Dow, Tosoh, Ruian ndi zomera zina zazikulu zidasinthidwa ndikusiya kupanga.

Wanhua Chemical, BASF, Huntsman, Covestro, ndi Dow amapanga 90% ya mphamvu yapadziko lonse lapansi yopanga MDI.Tsopano zida zotsogolazi zili mumayendedwe achilendo, ndipo zonse zasiya kupanga ndikusiya kupanga.Zopanga zatsika kwambiri.Msika wa MDI wakhala wosasunthika kwambiri.Mitengo yamsika yakwera motsatizanatsatizana.Pamene kutsika kumangofunika kutsata, osunga amakwera, ndipo mawu atsiku limodzi adzakwera ndi 100-350 yuan/ton.Zikuyembekezeka kuti MDI idzakwera kwambiri theka lachiwiri la chaka.

Zimphona zakweza malingaliro awo!Zopindulitsa mu gawo lachitatu zitha kuyembekezeka!
Kuyimitsidwa kwa kupanga ndi kukonza mafakitale akuluakulu kwapitirizabe kuwonjezeka, ndipo msika watsikanso.Pakalipano, mankhwala apamwamba kwambiri, opangidwa ndi mankhwala ambiri pamsika ayamba kukwera pang'onopang'ono.

Malinga ndi mndandanda wamakampani opanga mankhwala m'masiku 5 apitawa, zinthu zonse za 38 zamankhwala zikuchulukirachulukira.Zopindulitsa zitatu zapamwamba zinali: polymeric MDI (9.66%), formic acid (7.23%), ndi propane (6.22%).

Kukhazikika kwamitengo ya dziko kwabweretsanso mitengo yamankhwala ambiri pamlingo woyenera.Komabe, chifukwa cha kuwonjezeka kwaposachedwa kwa kuwongolera kotsogola komanso nthawi zambiri zosayembekezereka zamphamvu majeure, msika wayamba kudera nkhawa za kusowa kwa golidi, zisanu ndi zinayi ndi siliva, ndipo ogulitsa ena ayamba kugulitsa pamitengo yotsika munyengo yopuma.Zikuyembekezeka kuti padzakhala chiwopsezo cha kuchepa mu gawo lachinayi kapena mitengo yamsika idzakankhidwiranso.Tsopano tikuyang'anitsitsa msika wamankhwala osagwiritsidwa ntchito nthawi yayitali ndikusunga nthawi.
