Pofika pa July 2023, chiwerengero cha epoxy resin ku China chadutsa matani 3 miliyoni pachaka, kusonyeza kukula kwachangu kwa 12.7% m'zaka zaposachedwa, ndi kukula kwa makampani kupitirira chiwerengero cha kukula kwa mankhwala ochuluka.Zitha kuwoneka kuti m'zaka zaposachedwa, kuwonjezeka kwa ntchito za epoxy resin kwakhala kofulumira, ndipo mabizinesi ambiri adayikapo ndalama ndikukonzekera kumanga ntchito yayikulu.Malinga ndi ziwerengero, kukula kwa epoxy resin ku China kupitilira matani 2.8 miliyoni mtsogolomo, ndipo kukula kwamakampani kudzapitilira 18%.
Epoxy resin ndiye kupanga polymerization ya bisphenol A ndi Epichlorohydrin.Ili ndi mawonekedwe azinthu zamakina apamwamba, kugwirizana kolimba, kapangidwe kake kakang'ono ka maselo, magwiridwe antchito abwino kwambiri, kuchepa kwapang'onopang'ono (kukula kwazinthu kumakhala kokhazikika, kupsinjika kwamkati ndikochepa, ndipo sikuli kophweka kusweka), kutchinjiriza bwino, kukana kwa dzimbiri, kukhazikika bwino, komanso kutentha kwabwino (mpaka 200 ℃ kapena kupitilira apo).Choncho, chimagwiritsidwa ntchito zokutira, zipangizo zamagetsi, zipangizo gulu, zomatira ndi zina.

Kapangidwe ka epoxy resin nthawi zambiri amagawidwa munjira imodzi ndi njira ziwiri.Njira imodzi ndiyo kupanga utomoni wa epoxy pogwiritsa ntchito bisphenol A ndi Epichlorohydrin, womwe umagwiritsidwa ntchito popanga zolemera zochepa zama cell ndi sing'anga molekyulu yolemera epoxy resin;Njira ziwirizi zimaphatikizapo kupitiriza kuchitapo kanthu kwa utomoni wochepa wa maselo ndi bisphenol A. High molecular weight epoxy resin ikhoza kupangidwa kudzera mu sitepe imodzi kapena njira ziwiri.
Njira imodzi ndikuchepetsa bisphenol A ndi Epichlorohydrin mothandizidwa ndi NaOH, ndiye kuti, kutsegula mphete ndi kutsekeka kwa loop mumayendedwe omwewo.Pakalipano, kupanga kwakukulu kwa E-44 epoxy resin ku China kumapangidwa ndi njira imodzi.Njira ziwirizi ndizoti bisphenol A ndi Epichlorohydrin zimapanga diphenyl propane chlorohydrin etha pakati kupyolera mu Zowonjezera zomwe zimachitika mu sitepe yoyamba pansi pa chothandizira (monga Quaternary ammonium cation), ndiyeno kumachita zotsekeka pamaso pa NaOH. kupanga epoxy resin.Ubwino wa njira ziwiri ndi nthawi yochepa yochitira;Khola ntchito, yaing'ono kutentha kusinthasintha, zosavuta kulamulira;Nthawi yaying'ono yowonjezera alkali imatha kupewa hydrolysis ya epichlorohydrin.Njira ziwiri zopangira epoxy resin zimagwiritsidwanso ntchito kwambiri.

Gwero lachithunzi: China Industrial Information
Malinga ndi ziwerengero zoyenera, mabizinesi ambiri adzalowa mumakampani a epoxy resin mtsogolomo.Mwachitsanzo, matani 50000 a zida zamagetsi / chaka za Hengtai adzapangidwa kumapeto kwa 2023, ndipo matani 150000 a Mount Huangshan Meijia zida zatsopano / chaka zidzapangidwa mu Okutobala 2023. Zhejiang Zhihe New Materials '100000 ton/ zida za chaka zikuyembekezeka kupangidwa kumapeto kwa 2023, South Asia Electronic Materials (Kunshan) Co., Ltd. ikukonzekera kupanga zida ndi zida zokwana matani 300000 / chaka kuzungulira 2025, ndi Yulin Jiuyang High tech Materials Co. , Ltd. ikukonzekera kupanga zida za 500000 ton / chaka kuzungulira 2027. Malinga ndi ziwerengero zosakwanira, zidzawonjezeka kawiri m'tsogolomu pafupi ndi 2025.

Chifukwa chiyani aliyense akuyika ndalama pama projekiti a epoxy resin?Zifukwa zowunikira ndi izi:
Epoxy utomoni ndi chinthu chabwino kwambiri pakompyuta
Electronic sealant imatanthawuza mndandanda wa zomatira zamagetsi ndi zomatira zomwe zimagwiritsidwa ntchito kusindikiza zida zamagetsi, kuphatikiza kusindikiza, kusindikiza, ndi kuyika miphika.Zipangizo zamagetsi zopakidwa zimatha kugwira ntchito yosalowa madzi, yosagwedezeka, yosagwira fumbi, yosawononga dzimbiri, kuwononga kutentha, komanso chinsinsi.Choncho, guluu kuti apakidwe ali ndi makhalidwe kukana kutentha, kutsika kutentha kukana, mkulu Dielectric mphamvu, kutchinjiriza bwino, kuteteza chilengedwe ndi chitetezo.
Epoxy resin imakhala ndi kutentha kwabwino kwambiri, kutsekemera kwamagetsi, kusindikiza, katundu wa dielectric, mphamvu zamakina, ndi kuchepa pang'ono komanso kukana mankhwala.Pambuyo posakanizidwa ndi machiritso, imatha kukhala ndi magwiridwe antchito bwino komanso mawonekedwe onse azinthu zofunikira pakuyika zinthu zamagetsi, ndipo imagwiritsidwa ntchito kwambiri m'magawo monga zotengera zamagetsi.
Malinga ndi kafukufuku wochokera ku National Bureau of Statistics, kukula kwamakampani opanga zidziwitso zamagetsi mu 2022 kudakwera ndi 7.6% pachaka, ndipo kuchuluka kwa magwiritsidwe ntchito m'magawo ena amagetsi kudaposa 30%.Zitha kuwoneka kuti makampani apakompyuta aku China akadali pakukula mwachangu, makamaka m'mafakitale amagetsi omwe akuyang'ana kutsogolo monga ma semiconductors ndi 5G M'magawo monga luntha lochita kupanga ndi intaneti yazinthu, kukula kwa msika kwakhala nthawi zonse. patsogolo.
Pakadali pano, makampani ena a epoxy resin ku China akusintha kapangidwe kawo ndikuwonjezera gawo lazogulitsa zamtundu wa epoxy resin okhudzana ndi makampani opanga zamagetsi.Kuphatikiza apo, mabizinesi ambiri a epoxy resin omwe akukonzekera kumangidwa ku China amayang'ana kwambiri pamitundu yamagetsi yamagetsi.
Epoxy resin ndiye chinthu chachikulu pamasamba a turbine
Epoxy resin imakhala ndi makina abwino kwambiri, kukhazikika kwamankhwala, komanso kukana dzimbiri, ndipo imatha kugwiritsidwa ntchito ngati zida zamapangidwe, zolumikizira, ndi zokutira zamagetsi zamagetsi.Utomoni wa epoxy ukhoza kupereka mphamvu zambiri, kuuma kwakukulu, ndi kukana kutopa, kuonetsetsa kukhazikika ndi kudalirika kwa masamba, kuphatikizapo mawonekedwe othandizira, mafupa, ndi kulumikiza mbali za masamba.Kuphatikiza apo, utomoni wa epoxy ukhozanso kuwongolera kukana kukameta ubweya wamphepo komanso kukana kwa masamba, kuchepetsa kugwedezeka ndi phokoso la masamba, ndikuwongolera mphamvu yamagetsi opangira magetsi.
Pokutira masamba a turbine yamphepo, kugwiritsa ntchito utomoni wa epoxy ndikofunikira kwambiri.Popaka pamwamba pa masamba ndi epoxy resin, kukana kuvala ndi kukana kwa UV kwa masamba kumatha kupitilizidwa, ndipo moyo wautumiki wa masambawo ukhoza kukulitsidwa.Panthawi imodzimodziyo, imathanso kuchepetsa kulemera ndi kukana kwa masamba ndi kupititsa patsogolo mphamvu ya mphamvu ya mphepo.
Chifukwa chake, utomoni wa epoxy uyenera kugwiritsidwa ntchito kwambiri pazinthu zambiri zamagetsi zamagetsi.Pakadali pano, zida zophatikizika monga epoxy resin, carbon fiber, ndi polyamide zimagwiritsidwa ntchito ngati zida zopangira mphamvu zamagetsi.
Mphamvu zamphepo zaku China ndizotsogola padziko lonse lapansi, ndikukula kwapakati pachaka kupitilira 48%.Kupanga zida zogwirizana ndi mphamvu yamphepo ndiye gwero lalikulu lakukula kwa epoxy resin.Zikuyembekezeka kuti liwiro lamakampani opanga magetsi aku China lipitilize kukula kwa 30% mtsogolomo, komanso kugwiritsa ntchito utomoni wa epoxy ku China kudzawonetsanso kukula kwamphamvu.
Ma resin opangidwa mwamakonda komanso apadera a epoxy adzakhala odziwika bwino m'tsogolomu
Magawo ogwiritsira ntchito otsika a epoxy resin ndi ochulukirapo.Ngakhale motsogozedwa ndi kutukuka kwamakampani opanga mphamvu zatsopano, makampaniwa akula mwachangu, kukulitsa makonda, kusiyanitsa, komanso ukadaulo kudzakhalanso imodzi mwamagawo akulu azachitukuko.
Mayendedwe opangira makonda a epoxy resin ali ndi mayendedwe otsatirawa.Choyamba, halogen-free copper circuit board ili ndi kufunikira kogwiritsa ntchito mzere wa phenolic epoxy resin ndi Bisphenol F epoxy resin;Kachiwiri, kufunikira kwa o-methylphenol formaldehyde epoxy resin ndi hydrogenated bisphenol A epoxy resin ikukula kwambiri;Chachitatu, chakudya kalasi epoxy utomoni ndi mankhwala oyeretsedwanso ndi chikhalidwe epoxy utomoni, amene ali ndi ziyembekezo za chitukuko pamene ntchito zitini zitsulo, mowa, zakumwa carbonated, ndi zitini zipatso madzi;Chachinayi, mzere wopangira utomoni wamitundu ingapo ndi chingwe chopangira chomwe chimatha kupanga ma epoxy resins ndi zida zopangira, monga ma resins opangidwa ndi otsika.β- Phenol type epoxy resin, liquid crystal epoxy resin, special structure low viscosity DCPD type epoxy resin, ndi zina zotero.
Kumbali imodzi, imayendetsedwa ndi kugwiritsidwa ntchito m'munda wamagetsi otsika, ndipo kumbali ina, madera osiyanasiyana ogwiritsira ntchito komanso kutuluka kwa zitsanzo zambiri zapamwamba zabweretsa malo ambiri ogwiritsira ntchito pamakampani a epoxy resin.Zikuyembekezeka kuti kugwiritsidwa ntchito kwamakampani aku China epoxy resin kupitiriza kukula kopitilira 10% m'tsogolomu, komanso kukula kwamakampani a epoxy resin kungayembekezeredwe.
