Kuyambira pa September 16, chiwerengero cha mtengo wa mankhwala (CCPI) chinatsekedwa pa mfundo za 5199, kuwonjezeka kwa 0.6%.
Pakati pa mankhwala ofunikira omwe amawunikira, zinthu zonse za 37 zinanyamuka, zomwe zimawerengera 59.7%, ndipo zogulitsa zomwe zimawonjezeka kwambiri zinali adipic acid (7.3%) ndi butyl acrylate (7.1%);okwana 13 mankhwala anagwa, mlandu 21.0% , ndi mankhwala ndi kutsika kwambiri anali (4.3%) ndi acetonitrile (3.3%).
Adipic acid: Msonkhano wamsika ndiwodziwikiratu.Mtengo wazinthu zopangira zidakwera mkati mwa sabata, komanso kuchedwa kuyambitsanso chomera cha Haili, zomwe zidakulitsa malingaliro onse.Pambuyo pa tchuthi, opanga ma adipic acid adakweza mtengo wamndandanda kawiri, ndikukweza mtengo wamsika.Ndizokayikitsa kuti adipic acid ipitilira kukwera kwambiri pamsika wamawonekedwe.
Butyl Acrylate: Msika ukukula kwambiri.Malo ambiri opanga adayimitsidwa, ndipo chimphepocho chidakhudza magwiridwe antchito a mafakitale ku Jiangsu, Zhejiang ndi Shanghai, ndipo kupezeka konse m'munda kunali kolimba.Chifukwa cholimbikitsidwa ndi phindu, fakitale ya butyl ester yakula m'masiku aposachedwa, ndipo msika wamalonda watsatira zomwezo, ndipo sakufuna kugulitsa pamitengo yotsika.Zikuyembekezeka kuti msika wa butyl acrylate ukhoza kuyenda mwamphamvu.
PVC: Msika unanyamuka kenako unagwa.Kumayambiriro kwa sabata, nyengo yapakhomo yakhala ikuyenda bwino, ndikupangitsa mitengo ya PVC kukwera.Lachitatu, kuchuluka kwa kukwera kwa mitengo ku US kudaposa zomwe amayembekeza, chiwongola dzanja champhamvu cha Fed chikukwera, mlengalenga unachepa mphamvu, ndipo mitengo yamalo idakwera ndikutsika.Zikuyembekezeka kuti mtengo wa PVC pamawonekedwe amsika upitilira kusinthasintha.
Acetonitrile: Msika wagwa kuchokera pamlingo wapamwamba.Kumayambiriro koyambirira, ma seti angapo a ma acrylonitrile adasinthidwa pakatikati, ndipo mtengo wa mankhwala acetonitrile unakwera mofulumira.Komabe, kufunikira kwa mankhwala ophera tizilombo kumunsi ndi mafakitale ena a acetonitrile ndi ochuluka, ndipo maganizo odikira amatengedwa kuti atenge mtengo wamtengo wapatali wa acetonitrile, ndipo mawu a acetonitrile pang'onopang'ono amabwerera ku kulingalira.Zikuyembekezeka kuti msika wa acetonitrile upitilira kutsika mtsogolo.
Isobutyraldehyde: Mtengo wamsika wamsika wa isobutyraldehyde udapitilira kutsika mofooka.Chomera chamankhwala cha Tianjin chinayambiranso kugwira ntchito bwino, ndipo kupatsa kwa isobutyraldehyde kudakulitsidwanso.Komabe, kufunika kwa kutsika kwa mtsinje kunali kochepa, ndipo chitsenderezo cha katundu wa fakitale yaikulu chinawonekera, ndipo makampani ena adatsika.Ndi mtengo wakutsika wa isobutyraldehyde, msika uli ndi mlengalenga wolimba wodikirira ndikuwona.
Titanium dioxide: Mtengo wamsika wamsika wa titanium dioxide udapitilira kutsika.Msika wamsika wachikhalidwe unali wofooka pa nthawi yochuluka yofunidwa, ndipo kufunika sikunachuluke kwambiri.Makampani opanga zokutira adatsekeredwa pakugwa kwa msika wanyumba, ndipo mtengo wazinthu zopangira titaniyamu unatsika pang'ono.Mtengo wa sulfuric acid udapitilirabe kukhala wotsika.Titanium dioxide Msika umakhalabe wofooka.
Ponseponse, kwakanthawi kochepa, "Golden Nine Silver Ten" nthawi yochuluka yogwiritsira ntchito "Golden Nine Silver Ten" idzapitiriza kuyendetsa kufunikira kwa kufunikira, koma ziwopsezo zandale ndi zachuma zapadziko lonse lapansi sizikutha, ndipo msika wamankhwala uli ndi malo ochepa opitilira kukula pakati pa kuchira kofooka kwa kufunikira kwa terminal.
Malingaliro a kampani JIN DUN CHEMICALwapanga maziko apadera (meth) opanga ma acrylic monomer m'chigawo cha ZHEJIANG.Izi zimaonetsetsa kuti kukhazikika kwa HEMA, HPMA, HEA, HPA, GMA ndipamwamba kwambiri.Ma acrylate monomers athu apadera amagwiritsidwa ntchito kwambiri popangira ma thermosetting acrylic resins, crosslinkable emulsion polima, acrylate anaerobic zomatira, zomatira zamagulu awiri acrylate, zomatira zosungunulira, zomatira za emulsion acrylate, zomatira zamapepala ndi utoto wa acrylic. ndi apadera (meth) acrylic monomers ndi zotumphukira.Monga fluorinated acrylate monomers, Angagwiritsidwe ntchito ❖ kuyanika ❖ kuyanika wothandizila, utoto, inki, utomoni photosensitive, zipangizo kuwala, CHIKWANGWANI mankhwala, zosintha pulasitiki kapena munda mphira.Tikufuna kukhala ogulitsa kwambiri m'munda wawapadera acrylate monomers, kugawana zomwe takumana nazo ndi zinthu zabwino kwambiri komanso ntchito zamaluso.
