Tchati cha Trend cha Epoxy Resin

Sabata yatha, msika wa epoxy resin unali wofooka, ndipo mitengo yamakampani idatsika mosalekeza, yomwe nthawi zambiri inali yocheperako. Mu sabata, bisphenol A yopangira imagwira ntchito pang'onopang'ono, ndipo zopangira zina, epichlorohydrin, zimasinthasintha pansi pang'onopang'ono. Mtengo wonse wazinthu zopangira zidafooketsa kuthandizira kwake kwa zinthu zaposachedwa. Zida zapawiri zidapitilirabe kutsika mofooka, ndipo kufunikira kwa msika wa utomoni sikunasinthe. Zinthu zingapo zoyipa zidapangitsa kulephera kupeza chifukwa chabwino chamtengo wa epoxy resin. Mawu amtundu wachiwiri ndi wachitatu wa LER pamsika aperekedwa pa 15800 yuan/ton. Mitengo ya opanga akuluakulu akuluakulu yagwera pamtengo wotsika kwambiri chaka chino, ndipo padakali kuyembekezera kuchepetsa mtengo.
Sabata yatha, fakitale yayikulu ku Jiangsu idayima kuti ikonzere, ndipo zolemetsa zina zidasintha pang'ono. Zoyambira zonse zidatsika poyerekeza ndi sabata yatha. M'kati mwa mlungu, kutsika kwa mtsinje kunali kochepa, ndipo chikhalidwe cha maoda atsopano chinali chopepuka. Pokhapokha Lachitatu lapitalo, mlengalenga wofunsa ndi kubwezeretsanso udasinthidwa pang'ono, koma udali wolamulidwa ndi kuwonjezeredwa kofunikira. Kukakamizika kwa opanga utomoni kuti atumize ndikwambiri, ndipo mafakitale ena amva kuti zida zake ndizokwera pang'ono. Pali malire ambiri pakuperekedwa, ndipo cholinga cha malonda amsika ndichotsika.
Bisphenol A: Sabata yatha, mphamvu yogwiritsira ntchito zomera zapakhomo za bisphenol A zinali 62.27%, kutsika ndi 6.57 peresenti kuchokera pa November 3. Mu sabata ino ku South Asia kutsekedwa ndi kukonza pulasitiki, Nantong Star Bisphenol A Plant ikuyenera kutsekedwa kuti ikonzedwe. kwa sabata imodzi pa Novembara 7, ndipo Changchun Chemical Viwanda akuyembekezeka kutsekedwa kuti akonze mizere iwiri (mzere woyamba womwe kutsekedwa chifukwa cholephera pa Novembara 6, yomwe ikuyembekezeka kukhala sabata imodzi). Huizhou Zhongxin imatsekedwa kwakanthawi kwa masiku 3-4, ndipo palibe kusinthasintha kodziwikiratu pakulemetsa kwa mayunitsi ena. Chifukwa chake, kuchuluka kwa kagwiritsidwe ntchito kanyumba ka bisphenol A kumachepa.
Epichlorohydrin: Sabata yatha, kuchuluka kwa magwiritsidwe ntchito amakampani apakhomo a epichlorohydrin kunali 61.58%, kukwera 1.98%. Mu sabata, Dongying Liancheng 30000 t / chomera cha propylene chinatsekedwa pa October 26. Pakalipano, chloropropene ndiye chinthu chachikulu, ndipo epichlorohydrin sichinayambitsidwenso, ndipo ili mkati motsatira; Kutulutsa kwa tsiku ndi tsiku kwa epichlorohydrin ya Gulu la Binhua kudakwera mpaka matani 125 kuti azitha kuwongolera kumtunda kwa hydrogen chloride; Ningbo Zhenyang 40000 t/a glycerol process plant inayambikanso pa November 2, ndipo zomwe zikuchitika tsiku ndi tsiku ndi pafupifupi matani 100; Dongying Hebang, Hebei Jiaao ndi Hebei Zhuotai akadali pamalo oimikapo magalimoto, ndipo nthawi yoyambiranso ikutsatira; Mayendedwe a mabizinesi ena ali ndi kusintha pang'ono.
Tsogolo lamtsogolo la msika
Bisphenol Kugulitsa kwa msika kudakwera pang'ono kumapeto kwa sabata, ndipo mafakitale akumunsi anali osamala kwambiri polowa msika. Ofufuza zamsika amakhulupirira kuti: malingaliro a ogula ndi ogulitsa adzapitirizabe kusewera masewera sabata yamawa, ndi kusintha kochepa pazikhazikiko zanthawi yochepa. Zoyembekeza zofooka zomwe zimabweretsedwa ndi chipangizo chatsopano zidzapondereza malingaliro a msika, ndipo msika ukuyembekezeka kusintha mozungulira mtengo.
Cyclic chloride idapitilirabe. Kufufuza kwakukulu kwa chikhalidwe cha anthu komanso mphekesera zoti zigawo ziwiri za kumpoto kwa South zidzapangidwa mwezi wamawa zinapangitsa kuti anthu amsika akhale osamala ndipo mlengalenga wodikirira pamsika sunasinthe. Malingana ndi kufufuza kwa anthu omwe ali mkati, ngakhale kuti msika wamakono ndi wokhazikika kwakanthawi, ndizotheka kuti msika wamtsogolo upitirire kuchepa.
Kupereka kwa msika wa LER sikumangowonjezera kupanga zida zokonzera, komanso kumakhala ndi mphamvu zatsopano zomwe zimalowa pamsika. Zimamveka kuti chomera cha epoxy ku Wuzhong, Zhejiang (Shanghai Yuanbang No.2 Factory) chinayesedwa bwino masiku angapo apitawo. Pambuyo pa gulu lachiwiri, mtundu wa mankhwalawa wafika pafupifupi 15 #. Ngati ikupitirizabe kukhala yokhazikika m'tsogolomu, mankhwalawa sangalowe mumsika kwa nthawi yayitali. LER ipitiliza kuyimbanso kwake kofooka, komwe kumafunikira makamaka pakugula zinthu mokhazikika, ndipo ndizovuta kuwona zizindikiro zakuchira kwakanthawi kochepa.
