Muindasitiri yemagetsi emhepo, epoxy resin parizvino inoshandiswa zvakanyanya mumhepo turbine blade zvinhu.Epoxy resin ndeyepamusoro-inoshanda zvinhu zvine yakanakisa mechini zvivakwa, kugadzikana kwekemikari, uye kusagadzikana kwekuora.Mukugadzira mablades eturbine emhepo, epoxy resin inoshandiswa zvakanyanya muzvikamu zvezvimiro, majoini, uye machira emablades.Epoxy resin inogona kupa simba rakawanda, kuomarara kwepamusoro, uye kuramba kuneta muchimiro chinotsigira, skeleton, uye kubatanidza zvikamu zveblade, kuve nechokwadi kugadzikana uye kuvimbika kweblade.

Epoxy resin inogona zvakare kuvandudza kugera kwemhepo uye kupikisa kuramba kwemashizha, kuderedza blade vibration ruzha, uye kugadzirisa simba rekugadzira simba remhepo.Parizvino, epoxy resin uye girazi faibha yakagadziridzwa kurapa ichiri kushandiswa zvakananga mumhepo turbine blade zvinhu, izvo zvinogona kuvandudza simba uye kusagadzikana kwemarara.

Mumhepo turbine blade zvinhu, kushandiswa kwe epoxy resin kunodawo kushandiswa kwemakemikari zvigadzirwa seanorapa maajenti uye accelerators:

Chekutanga, inonyanya kushandiswa epoxy resin kurapa mumiririri mumhepo indasitiri yemagetsi ndeye polyether amine.

Chigadzirwa chakajairika ipolyether amine, inova zvakare inonyanya kushandiswa epoxy resin kurapa agent chigadzirwa muindasitiri yemagetsi emhepo.Polyether amine epoxy resin kurapa mumiririri inoshandiswa mukurapa matrix epoxy resin uye chimiro chekunamira.Iyo ine yakanakisa yakazara midziyo yakadai seyakaderera viscosity, hupenyu hurefu hwebasa, anti-kuchembera, etc. Yakashandiswa zvakanyanya mukugadzirwa kwemagetsi emhepo, kudhinda machira uye dhayi, njanji inopesana nekuora, bhiriji uye ngarava kudzivirira mvura, mafuta uye shale gasi kuongorora. nemimwe minda.Kudzika kwepolyether amine kunodarika 62% yesimba remhepo.Izvo zvinofanirwa kucherechedzwa kuti polyether amines ndeye organic amine epoxy resins.

Maererano nekuferefeta, polyether amines inogona kuwanikwa kuburikidza neamination ye polyethylene glycol, polypropylene glycol, kana ethylene glycol / propylene glycol copolymers pasi pekushisa kwepamusoro uye kumanikidzwa.Kusarudza akasiyana polyoxoalkyl zvimiro zvinogona kugadzirisa maitiro ekuita, kuoma, viscosity, uye hydrophilicity yepolyether amines.Polyether amine ine zvakanakira kugadzikana kwakanaka, kushoma kuchena, kupenya kwakanaka mushure mekurapa, uye kuoma kwakanyanya.Inogonawo kunyungudika muzvinonyungudutsa zvakadai semvura, ethanol, hydrocarbons, esters, ethylene glycol ethers, uye ketones.

Sekureva kweongororo, chiyero chekushandiswa kwemusika weChina wepolyether amine chakapfuura matani 100000, zvichiratidza kukura kweanopfuura 25% mumakore mashoma apfuura.Zvinotarisirwa kuti panosvika 2025, huwandu hwemusika wepolyether amines muChina huchapfuura matani 150000 munguva pfupi, uye kuwedzera kwekukura kwema polyether amines kunotarisirwa kunge kuri kutenderera 8% mune ramangwana.

Bhizinesi rekugadzira re polyether amine muChina iChenhua Co., Ltd., ine mabhesi maviri ekugadzira muYangzhou neHuai'an.Iine huwandu hunosvika 31000 matani / gore re polyether amine (yekupedzisira amino polyether) (kusanganisira dhizaini inokwana 3000 matani / gore re polyether amine chirongwa chiri kuvakwa), 35000 matani / gore yealkyl glycosides, 34800 matani / gore remoto retardants. , 8500 matani / gore resilicone rubber, 45400 matani / gore re polyether, 4600 matani / gore resilicone oiri, uye mamwe maitiro ekugadzira 100 matani / gore.Future Changhua Group inoronga kuisa mari inosvika mazana matanhatu emamiriyoni eyuan muHuai'an Industrial Park mudunhu reJiangsu kuti ivake kugadzirwa kwepagore kwe40000 matani epolyether amine uye 42000 matani emapurojekiti epolyether.

Pamusoro pezvo, mabhizinesi anomiririra epolyether amine muChina anosanganisira Wuxi Acoli, Yantai Minsheng, Shandong Zhengda, Real Madrid Technology, uye Wanhua Chemical.Zvinoenderana nehuwandu hwezvakarongwa pasi pezvirongwa zvekuvaka, iyo yakareba yakarongwa kugadzirwa kwe polyether amines muChina ichapfuura 200000 matani mune ramangwana.Zvinotarisirwa kuti nguva yakareba yekugadzirwa kwepolyether amines muChina ichapfuura matani 300000 pagore, uye maitiro ekukura kwenguva refu acharamba achikwira.

Kechipiri, inokurumidza kukura epoxy resin kurapa mumiririri mumhepo indasitiri yemagetsi: methyltetrahydrophthalic anhydride.

Zvinoenderana neongororo iyi, iyo inokurumidza kukura epoxy resin kurapa mumiririri mumhepo indasitiri yemagetsi ndeye methyltetrahydrophthalic anhydride kurapa mumiririri.Mumunda wesimba remhepo epoxy kurapa maajenti, kune zvakare methyl tetrahydrophthalic anhydride (MTHPA), inova ndiyo inonyanya kushandiswa kurapa epoxy resin yakavakirwa kabhoni faibha (kana girazi fiber) inosimbisa zvinhu zvinoumba mashizha emagetsi kuburikidza. extrusion molding process.MTHPA inoshandiswawo mune zvemagetsi ruzivo zvekushandisa, mishonga yemishonga, mishonga yezvipembenene, resin, uye maindasitiri ekudzivirira nyika.Methyl tetrahydrophthalic anhydride mumiriri akakosha weanhydride kurapa maajenti uye zvakare iri kukurumidza kukura mhando yeanorapa mumiriri mune ramangwana.

Methyltetrahydrophthalic anhydride inogadzirwa kubva kune maleic anhydride uye methylbutadiene kuburikidza nediene synthesis uyezve isomerized.Bhizinesi rinotungamira repamba ndiPuyang Huicheng Electronic Materials Co., Ltd., ine huwandu hwekushandisa hunosvika chiuru chematoni muChina.Nekukurumidza kukura kwehupfumi uye kukwidziridzwa kwekushandisa, kudiwa kwemachira, mapurasitiki, uye rabha kuri kuramba kuchiwedzera, zvichienderera mberi nekufambisa kukura kwemusika wemethyl tetrahydrophthalic anhydride.

Mukuwedzera, anhydride kuporesa mishonga inosanganisirawo tetrahydrophthalic anhydride THPA, hexahydrophthalic anhydride HHPA, methylhexahydrophthalic anhydride MHHPA, methyl-p-nitroaniline MNA, nezvimwewo. Zvigadzirwa izvi zvinogona kushandiswa mumunda wemhepo turbine blade epoxy resin curing agents.

Chetatu, epoxy resin kurapa maajenti ane mashandiro akanaka muindasitiri yemagetsi emhepo anosanganisira isophorone diamine uye methylcyclohexane diamine.

Pakati pe epoxy resin kurapa ejenti zvigadzirwa, yakanyanya-inoshanda kurapa ejenti mhando dzinosanganisira isoflurone diamine, methylcyclohexanediamine, methyltetrahydrophthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, methylhexahydrophthalic anhydride, methylringaniline anitro, mechanical, methylringani, etc. yakakodzera nguva yekushanda, yakaderera kurapa kupisa kuburitswa, uye yakanakisa jekiseni process operability, uye inoiswa mune inoumbwa zvinhu zveepoxy resin uye girazi faibha yemhepo turbine blades.Anhydride kurapa maajenti ndeekupisa kurapa uye akakodzera zvakanyanya kune extrusion molding process yemhepo turbine blades.

Mabhizinesi epasi rose ekugadzira isophorone diamine anosanganisira BASF AG kuGermany, Evonik Industries, DuPont muUnited States, BP kuUK, uye Sumitomo kuJapan.Pakati pavo, Evonik ndiyo yakakura isophorone diamine yekugadzira bhizinesi munyika.Mabhizinesi makuru eChinese Evonik Shanghai, Wanhua Chemical, Tongling Hengxing Chemical, nezvimwewo, ane chiyero chekushandisa chinosvika zviuru zana zvematani muChina.

Methylcyclohexanediamine inowanzova musanganiswa we 1-methyl-2,4-cyclohexanediamine uye 1-methyl-2,6-cyclohexanediamine.Iyo aliphatic cyclolkyl musanganiswa inowanikwa nehydrogenation ye2.4-diaminotoluene.Methylcyclohexanediamine inogona kushandiswa yega seanorapa epoxy resins, uye inogona zvakare kusanganiswa nemamwe akajairika epoxy kurapa maamines (akadai semafuta amines, alicyclic amines, anonhuwirira amines, acid anhydrides, nezvimwewo) kana general accelerators (senge tertiary amines). , imidazole).Vagadziri vanotungamira vemethylcyclohexane diamine muChina vanosanganisira Henan Leibairui New Material Technology Co., Ltd.

Zvinofanira kucherechedzwa kuti organic amine kurapa maajenti haana hushamwari kwezvakatipoteredza uye ane hupenyu hwakareba sesherufu yeanhydride kurapa maajenti, asi ari epamusoro mukuita uye nguva yekushandisa zvichienzaniswa neanhydride kurapa agent marudzi.

China ine akasiyana siyana epoxy resin kurapa ejenti zvigadzirwa mumhepo indasitiri yemagetsi, asi zvigadzirwa zvikuru zvinoshandiswa ndezvimwechete.Musika wepasirese urikushingairira kuongorora nekugadzira zvitsva epoxy resin kurapa agent zvigadzirwa, uye zvigadzirwa zveanorapa zvinogara zvichikwidziridzwa uye kudzokorora.Kufambira mberi kwezvigadzirwa zvakadaro mumusika weChinese kunononoka, zvakanyanya nekuda kwemutengo wakakwira weformula kutsiva epoxy resin inorapa agent zvigadzirwa muindasitiri yemagetsi emhepo, uye kusavapo kwezvigadzirwa zvakakwana.Nekudaro, nekuenderera mberi kwekufambira mberi kwetekinoroji uye kubatanidzwa kweepoxy resin kurapa vamiririri nemusika wepasirese, China epoxy resin inorapa zvigadzirwa mumunda wemagetsi emhepo ichaitawo kuenderera mberi nekuvandudzwa uye kudzokororwa.
