Ho kenella ha lehare la polyurethane ho ntlafala.
Hoa utloisisoa hore tlas'a maemo a tloaelehileng, likhahla tsa fan li entsoe haholo ka resin, likhoele tse matlafalitsoeng le lisebelisoa tsa mantlha.Hajoale, epoxy resin ke eona resin e ka sehloohong e sebelisoang ts'ebetsong ea li-blade tsa fan.Ha ho nahanoa ka litšenyehelo tsa resin, katleho ea tlhahiso, ho e sebelisa hape le lintlha tse ling, baetsi ba li-fan blade ba ntse ba batla litharollo tse ling.Har'a tsona, ha li bapisoa le lisebelisoa tsa khale tsa epoxy resin, lisebelisoa tsa resin ea polyurethane li na le melemo ea ho folisa habonolo le ho tšoarella ha nako e telele, 'me li nkuoa e le moloko o mocha oa lisebelisoa tse ka bang teng bakeng sa mahare a fan ke indasteri.
"Polyurethane resin ke sesebelisoa sa polymer se sebetsang hantle.Ka lehlakoreng le leng, ho tiea le ho hanyetsa mokhathala oa resin ea polyurethane li batla li le ntle, li finyella litlhoko tsa li-blades tsa fan;Ka lehlakoreng le leng, ha ho bapisoa le resin ea epoxy, theko ea polyurethane resin le eona e na le melemo e itseng, 'me ts'ebetso ea litšenyehelo e batla e phahame.” Feng Xuebin, Mookameli oa R&D oa New Materials Wind Power Products Division, o boletse puisanong.
Ka nako e ts'oanang, Costron o boetse a supa kenyelletsong ea sehlahisoa sa hae hore li-fan fan blades tsa polyurethane li na le thepa e ntle ea mochini, lebelo la tlhahiso e potlakileng, 'me li na le tlholisano e itseng ea' maraka, mme sekhahla sa ho kenella 'marakeng oa lehare la fan le sona se qalile ho eketseha.
Ho fihlela joale, Times New Materials e entse mefuta e fapaneng ea li-fan tsa polyurethane resin blades, tse bolelele ba tsona li tlohang ho 59.5 metres ho isa ho 94 metres.Moqapi oa lehare le sebopeho sa lera le tsona li fapane.Har'a bona, lehare la limithara tse 94 le ka sebelisoa ho fan ka matla a le mong a 8 megawatts.Ho utloisisoa hore li-polyurethane resin blades li kene mothating oa ts'ebeliso ea khoebo 'me li sebelisitsoe masimong a mangata a moea ho pholletsa le naha.
Ho hlakile hore tlhahiso ea thepa ea blade e potlakile.
