Malinga ndi ziwerengero zosakwanira, kuyambira koyambirira kwa Ogasiti mpaka 16 Ogasiti, kuwonjezeka kwamitengo yamakampani opanga mankhwala apanyumba kunadutsa kuchepa, ndipo msika wonse wachira.Komabe, poyerekeza ndi nthawi yomweyi mu 2022, idakali pansi.Pakali pano, kuchira m'mafakitale osiyanasiyana ku China sikwabwino, ndipo akadali a ulesi.Popanda kusintha kwa nyengo yazachuma, kubwezeredwa kwa mitengo yamtengo wapatali ndi khalidwe lachidule lomwe limapangitsa kuti zikhale zovuta kusunga mitengo.
Kutengera kusintha kwa msika, talemba mndandanda wazokwera mitengo yopitilira 70, motere:

Epoxy resin:Chifukwa cha kukopa kwa msika, makasitomala akunsi kwa madzi a epoxy resin ku South China ali osamala komanso alibe chidaliro pamsika wamtsogolo.Msika wamadzimadzi wa epoxy resin kudera la East China uli panjira komanso pamlingo wapamwamba.Kuchokera pamsika, ogwiritsa ntchito pansi sagula biluyo, koma amakhala ndi kukana, ndipo chidwi chawo chosungira ndi chochepa kwambiri.
Bisphenol A:Poyerekeza ndi zaka zapitazo, mtengo wamsika wapakhomo wa bisphenol A udakali wochepa, ndipo pali malo ambiri oti asinthe.Poyerekeza ndi nthawi yomweyi chaka chatha pa 12000 yuan / tani, yatsika ndi pafupifupi 20%.
Titanium dioxide:Ogasiti akadali nyengo yomaliza kumapeto, ndipo mabizinesi ambiri akumunsi adawonjezeranso zomwe amafunikira mwezi watha.Pakalipano, kufunitsitsa kugula mochulukira kwafowoka, zomwe zimapangitsa kuti msika ukhale wotsika kwambiri.Kumbali yoperekera, opanga ambiri amagwirabe ntchito yokonza kuti achepetse kupanga kapena kusintha zinthu munthawi yanthawi yopuma, zomwe zimapangitsa kuti pakhale zotulutsa zochepa pagawo loperekera.Posachedwapa, pakhala chizolowezi champhamvu cha kusinthasintha kwa mitengo ya titaniyamu woipa, yomwe yathandiziranso kukwera kwa mitengo ya titaniyamu.Poganizira zinthu zosiyanasiyana zamsika, msika wa titaniyamu wa dioxide pakadali pano uli pachiwopsezo pambuyo pokwera.
Epoxy chlororopane:Mabizinesi ambiri opanga ali ndi maoda atsopano okhazikika, pomwe madera ena ali ndi malonda osakwanira komanso kutumiza.Maoda atsopano amatha kukambirana, pomwe mabizinesi akumunsi amakhala osamala potsatira.Ogwiritsa ntchito ambiri akuda nkhawa ndi kusintha kwa kagwiritsidwe ntchito ka zida zapatsamba.
Propylene:Mtengo waukulu wa propylene m'chigawo cha Shandong udakali pakati pa 6800-6800 yuan/ton.Zikuyembekezeka kuti zogulitsa zichepa, chifukwa chake makampani opanga atsitsa mitengo yomwe atchulidwa, ndipo zomwe zikuchitika pamsika zikupitilizabe kukwera.Komabe, kufunikira kwa ma polypropylene akumunsi akadali ofooka, zomwe zapangitsa kuti pakhale zovuta pamsika.Chidwi chogula cha mafakitale ndichotsika, ndipo ngakhale mitengo ndi yokwera, kuvomereza kumakhalabe pafupifupi.Chifukwa chake, kuwonjezeka kwa msika wa propylene kumakhala kochepa pamlingo wina.
Phthalic anhydride:Mtengo wa ortho benzene wazinthu zopangira ukupitilirabe kukhala wokwera, ndipo msika wamafakitale wa naphthalene umakhalabe wokhazikika.Palinso chithandizo china kumbali ya mtengo, ndipo chifukwa cha mtengo wochepa, zowonjezeretsanso kumtunda zimawonjezeka pang'onopang'ono, kutulutsa ndalama zina zamalonda, zomwe zimapangitsa kuti malo a fakitale akhale ovuta kwambiri.
Dichloromethane:Mtengo wonse wakhala wokhazikika, ngakhale kuti mitengo ina yawonjezeka pang'ono, kuwonjezeka kumakhala kochepa.Komabe, chifukwa chamalingaliro amsika akukondera ku bearish, ngakhale zisonyezo zopitilirabe zomwe zimalimbikitsa msika, mlengalenga wonse udali wokondera ku bearish.Kuthamanga kwaposachedwa kwa malonda m'chigawo cha Shandong ndikwambiri, ndipo kubweza kwa mabizinesi kumathamanga.Zikuyembekezeka kuti pangakhale zovuta mu theka loyamba la sabata yamawa.Ku Guangzhou ndi madera ozungulira, zosungirako ndizotsika, kotero kusintha kwamitengo kumatha kutsalira pang'ono ku Shandong.
N-butanol:Potsatira kuwonjezeka kosalekeza kwa butanol, chifukwa cha kuyembekezera kupitiriza kukonza chipangizo, ogula otsika akuwonetsabe malingaliro abwino ogula panthawi yokonza mitengo, kotero n-butanol ikuyembekezeka kukhalabe yogwira ntchito mwamphamvu pakanthawi kochepa.
Acrylic acid ndi butyl ester:Chifukwa cholimbikitsidwa ndi kukwera kosalekeza kwa mtengo wa zinthu zopangira butanol komanso kusakwanira kwa malo azinthu zambiri za ester, omwe ali ndi ma ester alimbikira kwambiri pakuwonjezeka kwamitengo, zomwe zalimbikitsa kufunikira kolimba kuchokera kumunsi kuti alowe mumsika, ndipo malo ogulitsa akwera pamwamba. .Zikuyembekezeka kuti butanol yaiwisi ipitilira kugwira ntchito mwamphamvu, ndipo msika wa ester ukuyembekezeka kupitiliza kukwera kwake.Komabe, chidwi chiyenera kuperekedwa ku kuvomereza kutsika kwa mitengo yatsopano yomwe ikukwera mofulumira.
