I-polyurethane, i-polyester resin, i-carbon fibre nezinye izinto ezintsha ze-blade zihlala zivela, futhi inqubo emisha yezinto ze-fan blade ngokusobala iyashesha.Muva nje, umkhiqizi wama-blade i-Zhuzhou Times New Materials Technology Co., Ltd. (ngemuva kwalokhu ebizwa ngokuthi “I-Times New Materials”) kanye nomphakeli wezinto ezibonakalayo u-Kostron bamemezele ukuthi i-1000th polyurethane resin fan blade isikhishwe ngokusemthethweni emgqeni wokuhlanganisa, okwenza isethulo sokukhiqizwa kwenqwaba yama-polyurethane resin blades.

Eminyakeni yamuva, imboni yamandla omoya yaseChina ithuthuka ngesivinini esikhulu.Amaladi e-wind turbine alula, amakhulu futhi aqhubekele phambili abe isiqondiso esiyinhloko sokuthuthukiswa.Ngaphandle kwe-polyurethane resin, izinto ezintsha ze-blade ezifana ne-polyester resin ne-carbon fiber zihlala zivela, futhi inqubo emisha yezinto zensimbi yomoya we-turbine blade ngokusobala iye yashesha.
I-permeability ye-polyurethane blade iyathuthukiswa.
Kuyaqondakala ukuthi ngaphansi kwezimo ezijwayelekile, ama-fan blades akhiwa ikakhulukazi i-resin, imicu eqinisiwe kanye nezinto eziyinhloko.Njengamanje, i-epoxy resin iyinhlaka eyinhloko esetshenziswa ekukhiqizeni ama-fan blades.Uma kucatshangelwa izindleko ze-resin, ukusebenza kahle kokukhiqiza, ukugaywa kabusha nezinye izici, abakhiqizi be-fan blade bafuna ezinye izixazululo.Phakathi kwazo, uma kuqhathaniswa nezinto zendabuko ze-epoxy resin, izinto ze-polyurethane resin zinezinzuzo zokuphulukiswa okulula nokuqina okuphezulu, futhi zithathwa njengesizukulwane esisha sezinto ezingase zibe khona ze-resin zama-fan blades yimboni.
“I-polyurethane resin iyi-polymer esebenza kahle kakhulu.Ngakolunye uhlangothi, ukuqina nokumelana nokukhathala kwe-polyurethane resin kuhle, kuhlangabezana nezidingo zama-fan blades;Ngakolunye uhlangothi, uma kuqhathaniswa ne-epoxy resin, izindleko ze-polyurethane resin nazo zinezinzuzo ezithile, futhi ukusebenza kwezindleko kuphakeme kakhulu.” U-Feng Xuebin, umqondisi we-R&D we-New Materials Wind Power Products Division, esho engxoxweni.
Ngesikhathi esifanayo, u-Costron uphinde waveza esingenisweni somkhiqizo wakhe ukuthi ama-fan blade e-polyurethane anezakhiwo ezingcono zemishini, isivinini sokukhiqiza esisheshayo, futhi anokuncintisana okuthile kwemakethe, futhi izinga lokungena emakethe ye-fan blade nalo seliqalile ukwanda.
Kuze kube manje, i-Times New Materials isikhiqize izinhlobo ezahlukene zama-fan fan blades we-polyurethane, ezinobude obusuka kumamitha angu-59.5 kuya kumamitha angu-94.Ukwakheka kwe-blade kanye nesakhiwo sesendlalelo nakho kuhlukile.Phakathi kwabo, i-blade yamamitha angu-94 ingasetshenziswa ku-fan ngamandla owodwa we-megawatts angu-8.Kuyaqondakala ukuthi ama-polyurethane resin blades angenile esigabeni sokusetshenziswa kwezentengiselwano futhi asesetshenziswe emapulazini amaningi omoya ezweni lonke.
Ukuqamba okusha kwe-blade kuyashesha ngokusobala.
Eqinisweni, ngaphandle kwe-polyurethane resin, eminyakeni yamuva nje, olunye ucwaningo olusha ngezinto ezingavuthiwe zama-fan blades ekhaya naphesheya luvela njalo.Imikhiqizo eyinhloko yomkhiqizi we-Danish fan blade LM yi-polyester resin ne-glass fiber.Ngokusho kwemininingwane yewebhusayithi yenkampani, ngemuva kwezikhathi eziningi zokuthuthukiswa kwedizayini nokwenza, ama-polyester resin fan blade asethe ngokuphindaphindiwe irekhodi le-fan blade elide kunawo wonke emhlabeni.
Ukunakwa okwengeziwe kukhokhwe ku-carbon fiber njengendlela entsha esikhundleni se-glass fiber.Ngaphansi kwemfuneko yama-fan blades angasindi, i-carbon fibre ithandwa yimboni ngenxa yezakhiwo zayo eziqinile.Kulo nyaka nje, phakathi kwabakhiqizi basekhaya, abalandeli abethulwe abakhiqizi babalandeli abavamile njenge-Goldwind Technology, i-Yunda, i-Mingyang Intelligent, njll. bonke bathatha ama-blade ane-carbon fiber njenge-fiber eqinisayo.
U-Feng Xuebin utshele izintatheli ukuthi okwamanje, ukusungulwa kanye nokuthuthukiswa kwezinto ezisetshenziswa yi-wind turbine blade kugxile kakhulu ezinhlangothini ezintathu.Okokuqala, ngaphansi kwengcindezi yokulinganisa kwamandla omoya, ukukhiqizwa kwe-blade kunezidingo zokulawula izindleko eziphezulu, ngakho-ke kuyadingeka ukuthola izinto ze-blade ezinezindleko eziphezulu zokusebenza.Okwesibili, ama-blades adinga ukuqhubekela phambili azivumelanisa nemvelo yokuthuthukiswa kwamandla omoya.Isibonelo, ukuthuthukiswa okukhulu kwamandla omoya ogwini lolwandle kuzokhuthaza ukusetshenziswa kwezinto ezisebenza kahle ezifana ne-carbon fiber emkhakheni we-blade.Okwesithathu ukuxazulula izimfuno zokuvikela imvelo zama-blade.Ukugaywa kabusha kwezinto eziyinhlanganisela yama-wind turbine blades bekulokhu kuyinkinga enzima embonini.Ngalesi sizathu, imboni iphinde ifune isistimu yezinto ezisetshenziswayo ezigaywa kabusha nezisimeme.
Izinto ezintsha noma amathuluzi okunciphisa izindleko zamandla omoya.
Kuyaphawuleka ukuthi inqwaba yabangaphakathi embonini yatshela izintatheli ukuthi imboni ye-wind turbine blade ibhekene nengcindezi enkulu yokunciphisa izindleko esimweni samanje sokuwohloka kwentengo okusheshayo kwama-wind turbines.Ngakho-ke, ukusungulwa kwezinto ezintsha ze-blade kuzoba yisikhali esikhulu sokukhuthaza ukuncishiswa kwezindleko zamandla omoya.
I-Cinda Securities, isikhungo socwaningo lwemboni, iveze embikweni wayo wocwaningo ukuthi esakhiweni sezindleko zama-wind turbine blades, izindleko zezinto ezingavuthiwe zibalelwa ku-75% wesamba sezindleko zokukhiqiza, kanti phakathi kwezinto ezingavuthiwe, izindleko ze-fiber eqinisiwe. futhi i-resin matrix yenza u-21% no-33% ngokulandelana, okuyingxenye eyinhloko yezindleko zezinto zokusetshenziswa zama-blade enjini yomoya.Ngaso leso sikhathi, abantu embonini baphinde batshela izintatheli ukuthi ama-blades abiza cishe u-25% wezindleko zabalandeli, futhi ukuncishiswa kwezindleko ze-blade kuzokwehlisa kakhulu izindleko zokukhiqiza zabalandeli.
UCinda uphinde waveza ukuthi ngaphansi komkhuba wezinjini ezinkulu zomoya, ukwenziwa ngcono kwezakhiwo zemishini, isisindo esilula kanye nokunciphisa izindleko kuyizindlela eziphindaphindayo zobuchwepheshe bamanje bensingo ye-wind turbine blade, futhi indlela yakho yokubona kuzoba ukuthuthukiswa okuphindaphindwayo kwezinto ezisetshenziswa yi-wind turbine blade, izinqubo zokukhiqiza kanye nezakhiwo ze-blade, okubaluleke kakhulu okuwukuphindaphinda kohlangothi lwezinto ezibonakalayo.
“Ngokwesilinganiso esihlosiwe, ukusungulwa kwezinto ezintsha kuzoqhubeza imboni ukuthi yehlise izindleko ngalezi zici ezintathu ezilandelayo.Okokuqala, izindleko ze-blade material ngokwazo ziyancipha;okwesibili, i-blade engasindi izokhuthaza ukuncishiswa komthwalo we-turbine yomoya, ngaleyo ndlela kunciphise izindleko zokukhiqiza;okwesithathu, i-wind turbine blade idinga izinto zokusebenza eziphezulu ukuze ivumelane nenkambiso yenjini yomoya emikhulu, ngaleyo ndlela ibona ukuncipha kwezindleko zamandla.” kusho uFeng Xuebin.
Ngasikhathi sinye, uFeng Xuebin uphinde wakhumbuza ukuthi eminyakeni yamuva nje, ukuphindaphinda kobuchwepheshe bemboni yamandla omoya yasekhaya kuye kwashesha, okuye kwakhuthaza ngokushesha ukuthuthukiswa kwemboni.Kodwa-ke, ohlelweni lwentuthuko, imboni kufanele inake kakhulu ukwethembeka kobuchwepheshe obusha, inciphise ubungozi bokusebenzisa ubuchwepheshe obusha, futhi ikhuthaze ukuthuthukiswa kwekhwalithi ephezulu yayo yonke imboni.
Isimemezelo:Okunye okuqukethwe kuvela ku-inthanethi, futhi umthombo uqashelwe.Zisetshenziselwa kuphela ukukhombisa amaqiniso noma imibono eshiwo kulesi sihloko.Ezokuxhumana nokufunda kuphela, futhi akuzona ezezinye izinjongo zentengiso.Uma kukhona ukwephulwa komthetho, sicela usithinte ukuze sikususe ngokushesha.
