Mu nganda zikoresha ingufu z'umuyaga, epoxy resin ikoreshwa cyane mubikoresho byumuyaga wa turbine.Epoxy resin ni ibikoresho-bikora cyane bifite ibikoresho byiza bya mashini, imiterere yimiti, hamwe no kurwanya ruswa.Mu gukora ibyuma bya turbine yumuyaga, epoxy resin ikoreshwa cyane mubice byubaka, guhuza, no gutwikira ibyuma.Epoxy resin irashobora gutanga imbaraga nyinshi, gukomera kwinshi, hamwe no kurwanya umunaniro muburyo bufasha, skeleton, hamwe no guhuza ibice byicyuma, bikarinda umutekano kandi wizewe.

Epoxy resin irashobora kandi kunoza imishwarara yumuyaga no kurwanya ingaruka zicyuma, kugabanya urusaku rwinyeganyeza, no kunoza ingufu zumuyaga.Kugeza ubu, epoxy resin na fibre fibre yahinduwe ikiza iracyakoreshwa muburyo butaziguye ibikoresho byumuyaga wa turbine, bishobora kunoza imbaraga no kurwanya ruswa.

Mu bikoresho byumuyaga wa turbine, gukoresha epoxy resin bisaba kandi gukoresha ibicuruzwa nkimiti nko gukiza imiti nihuta:

Ubwa mbere, ikoreshwa rya epoxy resin ikiza cyane mubikorwa byingufu zumuyaga ni polyether amine

Igicuruzwa gisanzwe ni polyether amine, nacyo gikunze gukoreshwa cyane epoxy resin ikiza ibicuruzwa munganda zumuyaga.Polyether amine epoxy resin ikiza ikoreshwa mugukiza matrix epoxy resin hamwe na adhesive yubatswe.Ifite ibintu byiza cyane byuzuye nkubukonje buke, ubuzima bumara igihe kirekire, kurwanya gusaza, nibindi. Byakoreshejwe cyane mugukora amashanyarazi yumuyaga, gucapa imyenda no gusiga irangi, gari ya moshi irwanya ruswa, ikiraro nubwato butangiza amazi, peteroli na shale n'indi mirima.Hasi ya polyether amine irenga 62% yingufu zumuyaga.Twabibutsa ko amine polyether ari aya amine epoxy resin.

Nk’uko iperereza ryabigaragaje, amine polyether irashobora kuboneka hifashishijwe amine ya polyethylene glycol, polypropilene glycol, cyangwa Ethylene glycol / propylene glycol copolymers munsi yubushyuhe bwinshi nigitutu.Guhitamo imiterere itandukanye ya polyoxoalkyl irashobora guhindura ibikorwa byimyitwarire, ubukana, ubukonje, na hydrophilicity ya polyether amine.Polyether amine ifite ibyiza byo gutuza neza, kwera gake, gloss nziza nyuma yo gukira, no gukomera cyane.Irashobora kandi gushonga mumashanyarazi nkamazi, Ethanol, hydrocarbone, esters, etylene glycol ethers, na ketone.

Ubushakashatsi bwerekanye ko igipimo cy’imikoreshereze y’isoko rya amine mu Bushinwa kirenga toni 100000, kigaragaza umuvuduko w’ubwiyongere bwa 25% mu myaka mike ishize.Biteganijwe ko mu 2025, ingano y’isoko rya amine polyether mu Bushinwa izarenga toni 150000 mu gihe gito, kandi biteganijwe ko umuvuduko w’imikoreshereze ya amine polyether amine uzaba hafi 8% mu gihe kiri imbere.

Uruganda rukora polyether amine mu Bushinwa ni Chenhua Co., Ltd, ifite ibirindiro bibiri by’umusaruro i Yangzhou na Huai'an.Ifite toni 31000 / yumwaka ya polyether amine (iherezo rya amino polyether) (harimo ubushobozi bwo gushushanya toni 3000 / umwaka wumushinga wa polyether amine urimo kubakwa), toni 35000 / umwaka wa alkyl glycoside, toni 34800 / yumwaka wa retardants , Toni 8500 / umwaka wa reberi ya silicone, toni 45400 / umwaka wa polyether, toni 4600 / umwaka wamavuta ya silicone, nubundi bushobozi bwa toni 100 / kumwaka.Future Changhua Group irateganya gushora hafi miliyoni 600 Yuan muri Parike y’inganda ya Huai'an mu Ntara ya Jiangsu kubaka buri mwaka umusaruro wa toni 40000 za polyether amine na toni 42000 z’imishinga myinshi.

Byongeye kandi, ibigo bihagarariye polyether amine mu Bushinwa birimo Wuxi Acoli, Yantai Minsheng, Shandong Zhengda, Ikoranabuhanga rya Real Madrid, na Wanhua Chemical.Dukurikije imibare y’imishinga iteganijwe gukorwa mu iyubakwa, ubushobozi bw’igihe kirekire buteganijwe bwo gutanga amine polyether mu Bushinwa buzarenga toni 200000 mu gihe kiri imbere.Biteganijwe ko ubushobozi bwigihe kirekire bwo gukora amine polyether mu Bushinwa buzarenga toni 300000 ku mwaka, kandi iterambere ryigihe kirekire rizakomeza kuba hejuru.

Icya kabiri, epoxy resin ikura byihuse mumashanyarazi yinganda zumuyaga: methyltetrahydrophthalic anhydride

Nk’uko ubushakashatsi bubyerekana, imiti ikura yihuta cyane mu kuvura inganda z’umuyaga ni methyltetrahydrophthalic anhydride ikiza.Mu rwego rwumuyaga wumuyaga epoxy ukiza, hariho na methyl tetrahydrophthalic anhydride (MTHPA), ikaba aribwo buryo bukoreshwa cyane mu gukiza indwara ya epoxy resin ikora cyane ya fibre karuboni (cyangwa fibre fibre) ishimangira ibikoresho bikomatanya ibyuma byumuyaga binyuze mumashanyarazi. uburyo bwo kubumba.MTHPA ikoreshwa kandi mubikoresho bya elegitoroniki, imiti, imiti yica udukoko, ibisigazwa, ninganda zigihugu zirinda igihugu.Methyl tetrahydrophthalic anhydride ni umuntu uhagarariye imiti igabanya ubukana bwa anhydride kandi ni nubwoko bukura bwihuse bwo kuvura mugihe kizaza.

Methyltetrahydrophthalic anhydride ikomatanyirizwa muri anhydride yumugabo na methylbutadiene binyuze muri synthesis ya diene hanyuma ikabikwa.Uruganda ruza ku isonga mu gihugu ni Puyang Huicheng Electronic Materials Co., Ltd., rukoresha toni igihumbi mu Bushinwa.Hamwe n’iterambere ryihuse ry’ubukungu no kuzamura ibicuruzwa, icyifuzo cyo gutwikira, plastiki, na reberi nacyo kigenda cyiyongera, bikomeza gutera imbere ku isoko rya methyl tetrahydrophthalic anhydride.

Byongeye kandi, anhydride ikiza kandi irimo tetrahydrophthalic anhydride THPA, hexahydrophthalic anhydride HHPA, methylhexahydrophthalic anhydride MHHPA, methyl-p-nitroaniline MNA, nibindi bicuruzwa bishobora gukoreshwa murwego rwumuyaga wa turbine blade epoxy resin.

Icya gatatu, epoxy resin ikiza imiti ifite imikorere myiza munganda zumuyaga zirimo diamine isophorone na methylcyclohexane diamine

Muri epoxy resin ikiza yibicuruzwa, ubwoko bukora cyane bwo gukiza ibintu harimo isoflurone diamine, methylcyclohexanediamine, methyltetrahydrophthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, methylhexahydrophthalic anhydride, methylhexahydrophthalic anhydride igihe gikwiye cyo gukora, ubushyuhe buke bwo gukiza, hamwe nuburyo bwiza bwo gutera inshinge, kandi bigashyirwa mubikoresho bigize epoxy resin na fibre fibre kumashanyarazi ya turbine.Ibikoresho bivura Anhydride nibyuma byo gushyushya kandi birakwiriye muburyo bwo gukuramo ibishishwa byumuyaga wa turbine.

Ibigo bitanga umusaruro ku isi bya diamine isophorone birimo BASF AG mu Budage, Evonik Industries, DuPont muri Amerika, BP mu Bwongereza, na Sumitomo mu Buyapani.Muri byo, Evonik nicyo kigo kinini cya isoforone diamine itanga umusaruro ku isi.Ibigo bikuru by’abashinwa ni Evonik Shanghai, Wanhua Chemical, Tongling Hengxing Chemical, nibindi, hamwe n’ikoreshwa rya toni zigera ku 100000 mu Bushinwa.

Methylcyclohexanediamine mubusanzwe ni uruvange rwa 1-methyl-2,4-cyclohexanediamine na 1-methyl-2,6-cyclohexanediamine.Nibintu bya alifatique cycloalkyl yabonetse na hydrogenation ya 2,4-diaminotoluene.Methylcyclohexanediamine irashobora gukoreshwa yonyine nkigikoresho cyo gukiza imiti ya epoxy, kandi irashobora kandi kuvangwa nizindi miti isanzwe ikiza epoxy (nka amine yibinure, amine alicyclicine, amine aromatic, anhydrides, nibindi) cyangwa umuvuduko rusange (nka amine ya kaminuza) , imidazole).Abakora ku isonga mu gukora methylcyclohexane diamine mu Bushinwa barimo Henan Leibairui New Material Technology Co., Ltd na Jiangsu Weiketerri Chemical Co., Ltd. Igipimo cy’imbere mu gihugu ni toni 7000.

Twabibutsa ko imiti ivura amine kama itangiza ibidukikije kandi ikagira ubuzima buramba nkibintu bivura anhydride, ariko birarenze mubikorwa ndetse nigihe cyo gukora ugereranije nubwoko butandukanye bwa anhydride.

Ubushinwa bufite ubwoko butandukanye bwa epoxy resin ikiza ibicuruzwa biva mu nganda zikoresha ingufu z'umuyaga, ariko ibicuruzwa nyamukuru bikoreshwa ni bimwe.Isoko mpuzamahanga ririmo gushakisha cyane no guteza imbere epoxy resin ikiza ibicuruzwa biva mu mahanga, kandi ibicuruzwa bivura bikomeza kuzamurwa no gusubiramo.Iterambere ryibicuruzwa nkibi ku isoko ryUbushinwa riratinda, cyane cyane bitewe nigiciro kinini cyo gusimbuza amata kugirango epoxy resin ikiza ibicuruzwa biva mu nganda zikoresha umuyaga, no kutagira ibicuruzwa byuzuye.Nyamara, hamwe n’iterambere rikomeje gutera imbere mu ikoranabuhanga no guhuza imiti igabanya ubukana bwa epoxy resin hamwe n’isoko mpuzamahanga, Ubushinwa bwa epoxy resin ikiza ibicuruzwa biva mu mashanyarazi y’umuyaga nabwo bizakomeza kuvugururwa no kugaruka.
