M'makampani opangira mphamvu zamphepo, epoxy resin imagwiritsidwa ntchito kwambiri pazinthu zatsamba la turbine turbine.Epoxy resin ndi chinthu chochita bwino kwambiri chokhala ndi makina abwino kwambiri, kukhazikika kwamankhwala, komanso kukana dzimbiri.Popanga masamba a turbine yamphepo, utomoni wa epoxy umagwiritsidwa ntchito kwambiri pazomangira, zolumikizira, ndi zokutira zamasamba.Utomoni wa epoxy ukhoza kupereka mphamvu zambiri, kuuma kwakukulu, ndi kukana kutopa muzitsulo zothandizira, chigoba, ndi kulumikiza mbali za tsamba, kuonetsetsa kukhazikika ndi kudalirika kwa tsamba.

Epoxy resin imathanso kupititsa patsogolo kumeta ubweya wamphepo ndi kukana kwa masamba, kuchepetsa phokoso lakugwedezeka kwa tsamba, ndikuwongolera mphamvu zamagetsi zamagetsi.Pakadali pano, utomoni wa epoxy ndi machiritso osinthidwa magalasi amagwiritsidwabe ntchito mwachindunji mu zida zamphepo zamphepo, zomwe zimatha kuwonjezera mphamvu komanso kukana dzimbiri.

Pazinthu zamphepo zamphepo, kugwiritsa ntchito epoxy resin kumafunikiranso kugwiritsa ntchito mankhwala monga machiritso ndi ma accelerator:

Choyamba, chomwe chimagwiritsidwa ntchito kwambiri pochiritsa epoxy resin pamakampani opanga mphamvu zamagetsi ndi polyether amine.

Chinthu chodziwika bwino ndi polyether amine, yomwe imagwiritsidwanso ntchito kwambiri pochiritsa epoxy resin pamakampani opanga mphamvu zamphepo.Polyether amine epoxy resin kuchiritsa wothandizila amagwiritsidwa ntchito pochiritsa matrix epoxy resin ndi zomatira zomangira.Ili ndi zinthu zabwino kwambiri zophatikizana monga kukhuthala kochepa, moyo wautali wautumiki, odana ndi ukalamba, etc. Zakhala zikugwiritsidwa ntchito kwambiri popanga mphamvu yamphepo, kusindikiza nsalu ndi utoto, anti-corrosion njanji, mlatho ndi sitima zotchingira madzi, kufufuza mafuta ndi shale gasi. ndi minda ina.Kutsikira kwa polyether amine kumapanga mphamvu yopitilira 62% yamphamvu yamphepo.Tiyenera kukumbukira kuti polyether amines ndi ya organic amine epoxy resins.

Malinga ndi kafukufukuyu, ma polyether amines amatha kupezeka ndi amination a polyethylene glycol, polypropylene glycol, kapena ethylene glycol/propylene glycol copolymers pansi pa kutentha kwambiri komanso kupanikizika.Kusankha mitundu yosiyanasiyana ya polyoxoalkyl kumatha kusintha momwe zimachitikira, kulimba, kukhuthala, ndi hydrophilicity ya polyether amines.Polyether amine ili ndi ubwino wokhazikika bwino, kuyera kochepa, gloss yabwino pambuyo pochiritsidwa, ndi kuuma kwakukulu.Ikhozanso kusungunuka mu zosungunulira monga madzi, ethanol, hydrocarbons, esters, ethylene glycol ethers, ndi ketoni.

Malinga ndi kafukufukuyu, kukula kwa msika waku China wa polyether amine wapitilira matani 100000, kuwonetsa kukula kwa 25% mzaka zingapo zapitazi.Zikuyembekezeka kuti pofika chaka cha 2025, kuchuluka kwa msika wa ma polyether amines ku China kupitilira matani 150000 pakanthawi kochepa, ndipo kukula kwa ma polyether amines akuyembekezeka kukhala pafupifupi 8% mtsogolomo.

Kampani yopanga polyether amine ku China ndi Chenhua Co., Ltd., yomwe ili ndi maziko awiri opangira ku Yangzhou ndi Huai'an.Ili ndi matani 31000 / chaka cha polyether amine (mapeto amino polyether) (kuphatikiza mphamvu yopangira matani 3000 / chaka cha pulojekiti ya polyether amine yomwe ikumangidwa), matani 35000 / chaka cha alkyl glycosides, matani 34800 / chaka cha zoletsa moto. , matani 8500/chaka cha rabara ya silikoni, matani 45400/chaka cha polyether, matani 4600/chaka cha mafuta a silikoni, ndi mphamvu zina zopangira matani 100/chaka.Future Changhua Group ikukonzekera kuyika ndalama zokwana pafupifupi 600 miliyoni ku Huai'an Industrial Park m'chigawo cha Jiangsu kuti amange matani 40000 a polyether amine ndi matani 42000 a polyether pachaka.

Kuphatikiza apo, mabizinesi oyimira polyether amine ku China akuphatikizapo Wuxi Acoli, Yantai Minsheng, Shandong Zhengda, Real Madrid Technology, ndi Wanhua Chemical.Malinga ndi ziwerengero za ntchito zomanga zomwe zakonzedwa, mphamvu yopangira ma polyether amines ku China ipitilira matani 200000 m'tsogolomu.Zikuyembekezeka kuti nthawi yayitali yopanga ma polyether amines ku China idzapitilira matani 300000 pachaka, ndipo kukula kwanthawi yayitali kupitilirabe kukhala kwakukulu.

Kachiwiri, epoxy resin kuchiritsa wothandizila omwe akukula kwambiri mumakampani opanga mphamvu zamagetsi: methyltetrahydrophthalic anhydride.

Malinga ndi kafukufukuyu, yemwe akukula mwachangu epoxy resin kuchiritsa wothandizila pamakampani opanga mphamvu zamagetsi ndi methyltetrahydrophthalic anhydride kuchiritsa wothandizira.M'munda wa mphamvu ya mphepo epoxy machiritso, palinso methyl tetrahydrophthalic anhydride (MTHPA), yomwe imagwiritsidwa ntchito kwambiri pochiritsa epoxy resin yochokera ku carbon fiber (kapena magalasi) extrusion akamaumba ndondomeko.MTHPA imagwiritsidwanso ntchito pazidziwitso zamagetsi, mankhwala, mankhwala ophera tizilombo, ma resin, ndi mafakitale achitetezo mdziko.Methyl tetrahydrophthalic anhydride ndi gawo lofunikira la machiritso a anhydride komanso mtundu womwe ukukula mwachangu mtsogolomo.

Methyltetrahydrophthalic anhydride imapangidwa kuchokera ku maleic anhydride ndi methylbutadiene kudzera mu diene synthesis kenako isomerized.Makampani otsogola apanyumba ndi Puyang Huicheng Electronic Materials Co., Ltd., omwe amagwiritsa ntchito matani pafupifupi chikwi ku China.Ndikukula mwachangu kwachuma komanso kukweza kwazakudya, kufunikira kwa zokutira, mapulasitiki, ndi mphira kukuchulukirachulukira, ndikupititsa patsogolo kukula kwa msika wa methyl tetrahydrophthalic anhydride.

Kuphatikiza apo, mankhwala ochiritsa anhydride amaphatikizanso tetrahydrophthalic anhydride THPA, hexahydrophthalic anhydride HHPA, methylhexahydrophthalic anhydride MHHPA, methyl-p-nitroaniline MNA, ndi zina zotere.

Chachitatu, ma epoxy resin machiritso omwe amagwira ntchito bwino kwambiri pamakampani opanga mphamvu zamagetsi akuphatikizapo isophorone diamine ndi methylcyclohexane diamine.

Pakati pa mankhwala epoxy resin kuchiritsa wothandizila, kwambiri mkulu-ntchito kuchiritsa wothandizila mitundu monga isoflurone diamine, methylcyclohexanediamine, methyltetrahydrophthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, methylhexahydrophthalic anhydride, methylringanini amphamvu, etc. nthawi yoyenera yogwiritsira ntchito, kutsika kwa kutentha kwachizindikiro chochepa, ndi kugwiritsira ntchito bwino kwa jekeseni, ndipo zimagwiritsidwa ntchito muzinthu zophatikizika za epoxy resin ndi magalasi opangira masamba a turbine.Ma Anhydride ochiritsa machiritso ndi a machiritso otenthetsera ndipo ndi oyenera kwambiri popangira ma turbine amphepo.

Makampani opanga padziko lonse lapansi a isophorone diamine akuphatikizapo BASF AG ku Germany, Evonik Industries, DuPont ku United States, BP ku UK, ndi Sumitomo ku Japan.Pakati pawo, Evonik ndiye bizinesi yayikulu kwambiri padziko lonse lapansi yopanga isophorone diamine.Mabizinesi akuluakulu aku China ndi Evonik Shanghai, Wanhua Chemical, Tongling Hengxing Chemical, ndi zina zambiri, okhala ndi matani pafupifupi 100000 ku China.

Methylcyclohexanediamine nthawi zambiri imakhala yosakaniza 1-methyl-2,4-cyclohexanediamine ndi 1-methyl-2,6-cyclohexanediamine.Ndi aliphatic cycloalkyl pawiri analandira ndi hydrogenation wa 2.4-diaminotoluene.Methylcyclohexanediamine ingagwiritsidwe ntchito yokha ngati mankhwala ochiritsira a epoxy resins, ndipo imathanso kusakanikirana ndi zina zomwe zimagwiritsidwa ntchito pochizira epoxy (monga mafuta amines, alicyclic amines, amines onunkhira, acid anhydrides, etc.) kapena ma accelerators (monga ma amines apamwamba kwambiri , imidazole).Omwe amapanga methylcyclohexane diamine ku China akuphatikizapo Henan Leibairui New Material Technology Co., Ltd.

Zindikirani kuti ma organic amine machiritso sakhala okonda zachilengedwe ndipo amakhala ndi nthawi yayitali ngati mankhwala ochiritsa a anhydride, koma amakhala apamwamba pakugwira ntchito komanso nthawi yogwiritsira ntchito poyerekeza ndi mitundu ya anhydride yochiritsa.

China ili ndi mitundu yosiyanasiyana ya epoxy resin kuchiritsa othandizira pamakampani opanga mphamvu yamphepo, koma zinthu zazikulu zomwe zimagwiritsidwa ntchito ndi amodzi.Msika wapadziko lonse lapansi ukufufuza mwachangu ndikupanga zinthu zatsopano za epoxy resin kuchiritsa, ndipo zinthu zochiritsa zimangotukuka ndikubwerezabwereza.Kupita patsogolo kwa zinthu zotere pamsika waku China kukucheperachepera, makamaka chifukwa cha kukwera mtengo kwa chilinganizo m'malo mwa epoxy resin kuchiritsa ma agent pamakampani amagetsi amphepo, komanso kusowa kwazinthu zonse.Komabe, ndi kupita patsogolo kosalekeza kwaukadaulo komanso kuphatikiza kwa ma epoxy resin ochiritsa othandizira ndi msika wapadziko lonse lapansi, China epoxy resin kuchiritsa ma agent mu gawo lamagetsi amphepo nawonso apitilizidwa kukonzanso ndikubwerezabwereza.
