I-polyurethane, i-polyester resin, i-carbon fiber kunye nezinye izinto ezintsha ze-blade zihlala zivela, kwaye inkqubo yokuvuselela izinto ze-fan blade ngokucacileyo iyakhawuleza.Kutshanje, umenzi weblade uZhuzhou Times New Materials Technology Co., Ltd. (emva koko ubizwa ngokuba yi "Times New Materials") kunye nomthengisi wezinto eziphathekayo uKostron ubhengeze ukuba i-1000th polyurethane resin fan blade iye yaqengqeleka ngokusemthethweni kumgca wokuhlanganisa, ukudala umzekelo wokuveliswa kwebhetshi ye-polyurethane resin blades.

Kwiminyaka yakutshanje, ishishini lamandla omoya laseTshayina likhula ngesantya esiphezulu.Iiblayidi zeinjini yomoya ezikhaphukhaphu, ezinkulu nezizinzileyo zibe yeyona ndlela iphambili yophuhliso.Ngaphandle kwe-polyurethane resin, izinto ezintsha ze-blade ezifana ne-polyester resin kunye ne-carbon fiber zihlala zivela, kwaye inkqubo yokuveliswa kwezinto ezintsha ze-wind turbine blade ngokucacileyo ikhawuleza.
I-permeability ye-polyurethane blade iphuculwe.
Kuyaqondwa ukuba phantsi kweemeko eziqhelekileyo, ii-fan blades ziqulunqwe kakhulu nge-resin, iifayili ezomeleziweyo kunye nezixhobo eziphambili.Okwangoku, i-epoxy resin yeyona ntlaka iphambili esetyenziswa kwinkqubo yokuvelisa ama-fan blades.Ukuqwalasela ixabiso le-resin, ukusebenza kakuhle kwemveliso, ukurisayikilisha kunye nezinye izinto, abavelisi be-fan blade bafuna ezinye izisombululo.Phakathi kwazo, xa kuthelekiswa nezinto zemveli ze-epoxy resin, izixhobo ze-polyurethane resin zinezibonelelo zokunyanga lula kunye nokuqina okuphezulu, kwaye zithathwa njengesizukulwana esitsha sezinto ezinokubakho ze-resin ze-fan blades lishishini.
“I-Polyurethane resin sisixhobo sepolymer esisebenza kakhulu.Ngakolunye uhlangothi, ukuqina kunye nokumelana nokudinwa kwe-polyurethane resin kulungile, ukuhlangabezana neemfuno zee-fan blades;Kwelinye icala, xa kuthelekiswa ne-epoxy resin, ixabiso le-polyurethane resin nalo linezibonelelo ezithile, kwaye ukusebenza kweendleko kuphezulu.” UFeng Xuebin, uMlawuli we-R&D weCandelo leMveliso yeMveliso yeMveliso yeMveliso yoMtsha, uthe kudliwano-ndlebe.
Kwangelo xesha, uCostron wachaza kwintshayelelo yakhe yemveliso ukuba i-polyurethane resin fan blade ineepropathi ezingcono zomatshini, isantya esikhawulezayo semveliso, kwaye inokhuphiswano oluthile lwentengiso, kwaye izinga lokungena kwimarike yee-fan blade nalo liqalile ukunyuka.
Ukuza kuthi ga ngoku, iTimes New Materials yenze iindidi ezahlukeneyo ze-polyurethane resin fan blades, ezinobude obusuka kwi-59.5 yeemitha ukuya kwi-94 yeemitha.Uyilo lwe-blade kunye nesakhiwo semaleko nazo zahlukile.Phakathi kwabo, i-blade yeemitha ezingama-94 ingasetyenziselwa umqhubi kunye namandla omnye we-8 megawatts.Kuyaqondwa ukuba ii-polyurethane resin blades ziye zangena kwinqanaba lokusetyenziswa kwezorhwebo kwaye ziye zasetyenziswa kwiifama ezininzi zomoya kwilizwe lonke.
Ukuveliswa kwezinto ezintsha zeblade ngokucacileyo kuyakhawuleza.
Ngapha koko, ngaphandle kwe-polyurethane resin, kwiminyaka yakutshanje, olunye uphando olutsha malunga nemathiriyeli ekrwada yee-blades zefeni ekhaya naphesheya zihlala zivela.Iimveliso eziphambili ze-Danish fan blade umenzi we-LM yi-polyester resin kunye ne-glass fiber.Ngokutsho kolwazi lwewebhusayithi yenkampani, emva kwamaxesha amaninzi ophuculo loyilo kunye nokwenza ngcono, i-polyester resin fan fan blades yenkampani iye yaphinda yabeka eyona rekhodi ende yehlabathi.
Ingqwalasela eyongezelelekileyo ihlawulwe kwifayibha yekhabhoni njengendawo entsha yefiber yeglasi.Ngaphantsi kwemfuneko yee-blades fan blades, i-carbon fiber ithandwa yi-industry ngenxa yeempawu zayo eziphezulu zamandla.Kanye kulo nyaka, phakathi kwabavelisi basekhaya, abalandeli abaveliswe ngabavelisi befenitshala abaqhelekileyo njengeGoldwind Technology, Yunda, Mingyang Intelligent, njl. njl
U-Feng Xuebin uxelele iintatheli ukuba ngoku, ukusungula izinto ezintsha kunye nophuhliso lwezixhobo zeblade ye-injini yomoya zigxininiswe kumacala amathathu.Okokuqala, phantsi koxinzelelo lokulingana kwamandla omoya, ukuveliswa kwe-blade kuneemfuno eziphezulu zokulawula iindleko, ngoko ke kuyimfuneko ukufumana izinto ze-blade kunye nokusebenza kweendleko eziphezulu.Okwesibini, ii-blades kufuneka zilungelelanise ngakumbi kwindawo yophuhliso lwamandla omoya.Umzekelo, uphuhliso olukhulu lwamandla omoya we-offshore luya kukhuthaza ukusetyenziswa kwezinto eziphezulu zokusebenza ezifana ne-carbon fiber kwibala le-blade.Eyesithathu kukusombulula amabango okhuseleko lwendalo esingqongileyo.Ukurisayikilishwa kwezinto ezidityanisiweyo zamagqabi einjini yomoya ibisoloko iyingxaki enzima kushishino.Ngesi sizathu, ishishini likwafuna inkqubo yemathiriyeli enokuphinda isetyenziswe nezinzileyo.
Izinto ezintsha okanye izixhobo zokunciphisa iindleko zamandla omoya.
Kuyaphawuleka ukuba inani labasebenzi bangaphakathi kwishishini baxelele iintatheli ukuba ishishini le-wind blade blade lijongene noxinzelelo olukhulu lokunciphisa iindleko kwimeko yangoku yokuhla kwexabiso elikhawulezayo lee-injini zomoya.Ke ngoko, ukwenziwa kwezinto ezintsha zeblade kuya kuba sisixhobo esikhulu sokukhuthaza ukucuthwa kweendleko zamandla omoya.
I-Cinda Securities, iziko lophando loshishino, libonise kwingxelo yalo yophando ukuba kwixabiso lexabiso lee-wind turbine blades, ixabiso lezinto ezibonakalayo libalelwa kwi-75% yeendleko ezipheleleyo zemveliso, ngelixa phakathi kwezinto eziluhlaza, ixabiso lefiber eqinisiweyo. kunye ne-resin matrix yenza i-21% kunye ne-33% ngokulandelelanayo, eyona nxalenye iphambili yeendleko zemathiriyeli ekrwada yamagqabi einjini yomoya.Kwangaxeshanye, abantu abakwishishini baxelele iintatheli ukuba iiblades zenza malunga ne-25% yeendleko zabalandeli, kwaye ukuncitshiswa kweendleko zezixhobo ze-blade kuya kuthoba kakhulu iindleko zokwenziwa kwabalandeli.
UCinda waphinda wachaza ukuba phantsi kwendlela yee turbines zomoya ezinkulu, ukwenziwa ngcono kweempawu zoomatshini, ubunzima bokukhanya kunye nokuncipha kweendleko ziintsingiselo eziphinda-phindayo zetekhnoloji yangoku yeblade ye-injini yomoya, kwaye indlela yayo yokuqonda iya kuba kukwandiswa okuphindaphindiweyo kwezixhobo zeblade ye-injini yomoya, iinkqubo zokuvelisa kunye nezakhiwo ze-blade, eyona nto ibaluleke kakhulu kukuphindaphinda kwecala lezinto eziphathekayo.
“Kwinjongo yokulinganisa, ukusungulwa kwezinto ezintsha kuya kuqhuba ishishini ukunciphisa iindleko kule miba mithathu ilandelayo.Okokuqala, iindleko zezinto ze-blade ngokwayo ziyancipha;okwesibini, i-blade ekhaphukhaphu iya kukhuthaza ukucuthwa komthwalo we-injini yomoya, ngaloo ndlela ukunciphisa iindleko zokuvelisa;okwesithathu, iblayidi yeinjini yomoya idinga imathiriyeli yokusebenza ephezulu ukuziqhelanisa nentsingiselo ye-injini yomoya yomlinganiselo omkhulu, ngaloo ndlela iqonda ukuhla kweendleko zamandla.” utshilo uFeng Xuebin.
Kwangaxeshanye, uFeng Xuebin waphinda wakhumbuza ukuba kwiminyaka yakutshanje, itekhnoloji yetekhnoloji yasekhaya yamandla omoya iye yakhawuleza, ethe yakhuthaza uphuhliso lweshishini.Nangona kunjalo, kwinkqubo yophuhliso, ishishini kufuneka lihlawule ngakumbi ukuthembeka kobuchwephesha obutsha, ukunciphisa umngcipheko wokusetyenziswa kobuchwephesha obutsha, kunye nokukhuthaza uphuhliso oluphezulu lweshishini lonke.
