Kubva muna Chikunguru 2023, huwandu hwese epoxy resin muChina hwakapfuura matani mamirioni matatu pagore, zvichiratidza kukurumidza kukura kwe12.7% mumakore achangopfuura, nekukura kweindasitiri kunodarika avhareji yekukura kwemakemikari akawanda.Zvinogona kuonekwa kuti mumakore achangopfuura, kuwedzera kwemapurojekiti epoxy resin kwakakurumidza, uye mabhizinesi mazhinji akaisa mari uye akaronga kuvaka chirongwa chikuru.Sekureva kwehuwandu, chiyero chekuvaka epoxy resin muChina chichapfuura 2.8 miriyoni matani mune ramangwana, uye indasitiri chiyero chekukura chicharamba chichikwira kusvika panosvika gumi nemasere%.
Epoxy resin ndiyo polymerization kugadzirwa kwebisphenol A uye Epichlorohydrin.Iine hunhu hwepamusoro mechanicha zvinhu, kubatana kwakasimba, dense molecular chimiro, yakanakisa bonding performance, diki kurapa shrinkage (kukura kwechigadzirwa kwakagadzikana, kushushikana kwemukati kudiki, uye hakusi nyore kutsemuka), yakanaka insulation, yakanaka corrosion resistance, kugadzikana kwakanaka, uye kwakanaka kupisa kuramba (kusvika 200 ℃ kana kupfuura).Nokudaro, inoshandiswa zvakanyanya mukuputira, midziyo yemagetsi, composite zvinhu, zvinonamatira uye mamwe minda.

Maitiro ekugadzira epoxy resin anowanzo kukamurwa kuita nhanho imwe uye mbiri-nhanho nzira.Imwe nhanho nzira ndeyekugadzira epoxy resin nekuita kwakananga kwebisphenol A uye Epichlorohydrin, iyo inowanzoshandiswa kugadzira yakaderera molecular uremu uye yepakati molecular uremu epoxy resin;Nzira mbiri-nhanho inosanganisira kuenderera mberi kwekuita kwepasi molecular resin ne bisphenol A. High molecular weight epoxy resin inogona kugadzirwa nenzira imwe-nhanho kana mbiri-nhanho.
Imwe nhanho maitiro ndeyekudzikira bisphenol A uye Epichlorohydrin pasi pechiito cheNaOH, kureva, kuita kuvhura mhete uye kuvharika loop maitiro pasi pemamiriro akafanana ekuita.Parizvino, kugadzirwa kukuru kweE-44 epoxy resin muChina kunogadzirwa kuburikidza nedanho rimwe chete.Iyo nhanho mbiri-maitiro ndeyekuti bisphenol A uye Epichlorohydrin inogadzira diphenyl propane chlorohydrin ether yepakati kuburikidza neAddition reaction mudanho rekutanga pasi pechiito checatalyst (senge Quaternary ammonium cation), uyezve kuita yakavharwa-loop reaction pamberi peNaOH kusvika. kugadzira epoxy resin.Zvakanakira nzira mbiri-nhanho ipfupi kuita nguva;Kushanda kwakagadzikana, kushanduka kwekushisa kuduku, nyore kudzora;Ipfupi alkali yekuwedzera nguva inogona kudzivirira yakawandisa hydrolysis ye epichlorohydrin.Iyo-matanho maviri maitiro ekugadzira epoxy resin anoshandiswawo zvakanyanya.

Mufananidzo kunobva: China Industrial Information
Zvinoenderana nehuwandu hwakakodzera, mabhizinesi mazhinji achapinda epoxy resin indasitiri mune ramangwana.Semuyenzaniso, 50000 matani eHengtai zvigadzirwa zvemagetsi/gore zvichaiswa mukugadzirwa mukupera kwa2023, uye 150000 matani eMount Huangshan Meijia zvishandiso zvitsva/gore zvichaiswa mukugadzirwa muna Gumiguru 2023. Zhejiang Zhihe New Materials' 100000 ton/ midziyo yegore yakarongwa kuiswa mukugadzirwa mukupera kwa2023, South Asia Electronic Materials (Kunshan) Co., Ltd. inoronga kuisa mukugadzira 300000 ton/gore zvishandiso nemichina kutenderera 2025, uye Yulin Jiuyang High tech Materials Co. , Ltd. inoronga kuisa mukugadzira 500000 ton / gore zvishandiso zvakapoteredza 2027. Maererano nehuwandu husina kukwana, huchapeta kaviri mune ramangwana rakapoteredza 2025.

Sei munhu wese ari kuisa mari mumapurojekiti epoxy resin?Zvikonzero zvekuongorora ndezvizvi:
Epoxy resin yakanakisa yemagetsi kurongedza zvinhu
Electronic sealant inoreva nhevedzano yemagetsi anonamira uye anonamira anoshandiswa kunama midziyo yemagetsi, kusanganisira kuisa chisimbiso, kuisa chisimbiso, uye kuputira.Midziyo yemagetsi yakarongedzerwa inogona kutamba isingapinde mvura, inovhundutsa, isingapindi guruva, inodzivirira kupisa, inobvisa kupisa, uye basa rekuvanzika.Naizvozvo, glue rinozoiswa mukati rine hunhu hwekupikisa tembiricha yakakwira, kushomeka kwekushisa kwekushisa, simba reDielectric, simba rekudzivirira, kuchengetedza kwezvakatipoteredza uye kuchengetedza.
Epoxy resin ine yakanakisa kupisa kupisa, kuvharwa kwemagetsi, kuvhara, dielectric zvivakwa, mechanical zvivakwa, uye kudiki shrinkage uye makemikari kuramba.Mushure mekusanganiswa nevamiriri vekurapa, inogona kuve nekushanda kuri nani uye ese emhando yezvinhu zvinodiwa pakurongedza zvinhu zvemagetsi, uye inoshandiswa zvakanyanya muminda yakadai seyemagetsi zvinhu kurongedza.
Zvinoenderana nedata kubva kuNational Bureau of Statistics, chiyero chekukura kweindasitiri yekugadzira ruzivo rwemagetsi muna 2022 yakawedzera ne7.6% gore negore, uye kuwedzera kwekukura kwekushandisa mune mamwe minda yemagetsi yakapfuura 30%.Zvinogona kuoneka kuti indasitiri yemagetsi yeChina ichiri munzira yekukura nekukurumidza, kunyanya mumaindasitiri anotarisa mberi emagetsi akadai semiconductors uye 5G Muminda yakadai sehungwaru hwekugadzira uye Internet yezvinhu, kukura kwekukura kwemusika kwagara kuri. kure mberi.
Parizvino, mamwe makambani epoxy resin muChina ari kushandura chimiro chavo chechigadzirwa uye kuwedzera chikamu chechigadzirwa cheepoxy resin mabhureki ane chekuita neindasitiri yezvigadzirwa zvemagetsi.Uye zvakare, mazhinji emabhizinesi epoxy resin akarongwa kuvakwa muChina anonyanya kutarisa pane zvemagetsi zvigadzirwa zvigadzirwa.
Epoxy resin ndicho chinhu chikuru chemhepo turbine blades
Epoxy resin ine yakanakisa mechaniki zvivakwa, kugadzikana kwemakemikari, uye corrosion resistance, uye inogona kushandiswa sema blade structural components, connectors, uye machira ekugadzira magetsi emhepo.Epoxy resin inogona kupa simba rakawanda, kuoma kwepamusoro, uye kuramba kuneta, kuve nechokwadi kugadzikana uye kuvimbika kwemashizha, kusanganisira chimiro chinotsigira, skeleton, uye kubatanidza zvikamu zvemashizha.Uye zvakare, epoxy resin inogona zvakare kuvandudza mhepo shear kuramba uye kukanganisa kuramba kwemashizha, kuderedza kuzunguzika uye ruzha rwemashizha, uye kuvandudza kushanda kwesimba remhepo.
Mukuputira kwemhepo turbine blades, kushandiswa kwe epoxy resin kunokosha zvakare.Nekupfekedza pamusoro pemablades ne epoxy resin, kupfeka kuramba uye UV kupikisa kwemablades kunogona kuvandudzwa, uye hupenyu hwesevhisi hwemashizha hunogona kuwedzerwa.Panguva imwecheteyo, inogonawo kuderedza huremu uye kuramba kwemashizha uye kuvandudza kushanda kwekugadzira simba remhepo.
Naizvozvo, epoxy resin inoda kushandiswa zvakanyanya mune akawanda maficha emhepo indasitiri yemagetsi.Parizvino, zvinhu zvakaumbwa senge epoxy resin, kabhoni faibha, uye polyamide zvinonyanya kushandiswa semablade zvinhu zvekugadzira simba remhepo.
Simba remhepo reChina riri munzvimbo inotungamira pasi rose, neavhareji yekukura kwepagore inopfuura 48%.Kugadzirwa kwemidziyo inoenderana nemagetsi emhepo ndiyo inonyanya kutyaira yekukura nekukurumidza kwekushandisa epoxy resin chigadzirwa.Zvinotarisirwa kuti kumhanya kweChina indasitiri yemagetsi emhepo inochengetedza kukura kweanopfuura 30% mune ramangwana, uye kushandiswa kwe epoxy resin muChina kunoratidzawo kuputika kwekukura maitiro.
Yakagadzirirwa uye yakakosha epoxy resins ichave yakanyanya mune ramangwana
Iwo epoxy resin epoxy resin ari pasi pemvura akawandisa.Kunyangwe ichitungamirwa nekuvandudzwa kweiyo indasitiri yesimba idzva, indasitiri iyi yakasimukira nekukurumidza muhukuru, kusimudzira kwekugadzirisa, kusiyanisa, uye hunyanzvi kuchavawo imwe yenzira huru dzekusimudzira indasitiri.
Iyo yekuvandudza nzira ye epoxy resin customization ine inotevera nzira yekushandisa.Chekutanga, halogen-isina mhangura yedunhu bhodhi ine inogona kudiwa yekushandiswa kwemutsara phenolic epoxy resin uye Bisphenol F epoxy resin;Chechipiri, kudiwa kwekushandisa kweo-methylphenol formaldehyde epoxy resin uye hydrogenated bisphenol A epoxy resin iri kukurumidza kukura;Chetatu, chikafu chegiredhi epoxy resin chigadzirwa chakawedzera kucheneswa nechakare epoxy resin, chine tarisiro yebudiriro kana yaiswa kumagaba esimbi, doro, zvinwiwa zvecarbonated, uye magaba emichero yemichero;Chechina, iyo yakawanda-inoshanda resin yekugadzira mutsara mutsara wekugadzira unogona kugadzira ese epoxy resin uye mbishi zvinhu, senge yakachena yakaderera-giredhi composite resins.β- Phenol type epoxy resin, liquid crystal epoxy resin, special structure low viscosity DCPD type epoxy resin, etc. Aya epoxy resin achave nenzvimbo yakakura yekusimudzira mune ramangwana.
Kune rumwe rutivi, inofambiswa nekushandiswa munzvimbo yemagetsi yakadzika, uye kune rumwe rutivi, nzvimbo dzakasiyana-siyana dzekushandisa uye kubuda kwemhando dzakawanda dzepamusoro-soro dzakaunza nzvimbo dzakawanda dzekushandisa kune epoxy resin industry.Zvinotarisirwa kuti kushandiswa kweChina epoxy resin indasitiri kuchachengetedza kukurumidza kukura kweanopfuura gumi muzana mune ramangwana, uye kusimudzira kweiyo epoxy resin indasitiri inogona kutarisirwa.
