Njengoba kuthambekele ekubhekeni kwamaqabunga amakhulu e-wind turbine asogwini lolwandle, ukuzinza, amandla, kanye nokuhambisana kwenqubo kwezinhlelo zezinto ezihlanganisiwe kunquma ngqo isikhathi sokuphila kwamaqabunga kanye nokusebenza kahle kokukhiqizwa kwamandla. Njengesisekelo esiyinhloko sokuqinisa amagobolondo ama-blade, ama-web, imiphetho ehamba phambili, imiphetho elandelanayo, nezinye izingxenye,umbhede wezintambo oqoshiwe (CSM)sekuyinto ejwayelekile yokufaka i-VARTM vacuum kanye nokubumba ngesandla/ukucindezela ngenxa yokufana kwayo okuhle kakhulu, ukufakwa okusheshayo, ukubumba okungcono kakhulu, kanye nokubopha okuqinile kwe-interlaminar. Ukukhetha okungalungile kwebanga noma isisindo kungabangela izinkinga ezincane njengeziphambeko zobuso noma izikhala ze-resin ngesikhathi sokufakwa, noma kuphazamise kakhulu amandla esakhiwo kanye nokusebenza kokukhathala. Leli phepha lichaza ngokuhlelekile amamaki ajwayelekile, imininingwane eyinhloko, i-logic yokukhetha, kanye nokuhambisana kokusetshenziswa kwama-strand mat aqoshiwe asetshenziswa kuma-wind turbine blades.
Uhlaka Oluqoshiwe Lwe-StrandAma-Wind Turbine Blades: Ukubekwa Kwesisekelo Nezidingo Eziyinhloko
Ama-strand mat aqoshiwe e-wind turbine blade asebenzisa ngokufanayo imicu ye-E-glass engena-alkali enobubanzi obungu-9–13μm kanye nobude obuqoshiwe obungu-12–25mm, ehlangabezana nezindinganiso ze-GB/T 17470 futhi ehambisana nezinhlelo ze-resin ze-epoxy/vinyl ester.
Izithiyo Zokusebenza Eziyinhloko
- Ukuphambuka kwesisindo sendawo: ± 5%
- Okuqukethwe komswakama: ≤0.2%
- Amandla okuthamba: ≥30–180 N/5 cm (kuyanda ngesisindo esiyisisekelo)
- Ukungangenwa: Ukugcwala okusheshayo, ukubila okuphansi, okufanelekela ukufuthwa nge-vacuum
- Ukumelana nesimo sezulu/usawoti: Kudingeka ukuvikelwa kokugqwala okuthuthukisiwe kumamodeli asogwini lolwandle
- Ukuqina: Akukho ukuchitheka kwempuphu, akukho ukuhlukaniswa, akukho ukufiphaza; kufanelekile ukulayishwa okuzenzakalelayo
Umata oqoshiwe wezintambo usebenza ngokuyinhloko ekuqiniseni umthwalo ongewona oyinhloko, ukufana kwendawo, ukuguquka kwezingqimba, kanye nokumelana nokuguquguquka kwama-blades. Wakha ungqimba oluphelele lwesakhiwo uma luhlanganiswa nezindwangu eziqonde ngqo, izindwangu ezinama-axial amaningi, omata abaqhubekayo, kanye nomata abangaphezulu.
I-Wind Turbine BladeUhlaka Oluqoshiwe Lwe-StrandAmamodeli kanye Nemininingwane
Amamodeli ajwayelekile embonini afaka izinhlobo ze-EMC (emulsion)/CMC (impuphu) ezinobubanzi obujwayelekile obungu-1250/1040/2500 mm. Ngezansi amamodeli asetshenziswa kakhulu ekukhiqizeni ubukhulu be-blade:
1) Amamodeli Ajwayelekile kanye neMigomo Ehambisanayo

2) Ukukhetha Uhlobo Lokunamathela
- I-EMC esekelwe ku-Emulsion: Amandla aphezulu, ukufana okuhle kakhulu, ukuhambisana okuhle kwe-resin; kuyathandwa kakhulu ekufakweni kwe-vacuum
- I-CMC esekelwe ku-powder: Ingena ngokushesha, ingabizi kakhulu, ifanelekela izinqubo zokubeka izandla/zokusiza
- Amandla omoya angaphandle kolwandle, ama-blade anamandla aphezulu: Beka phambili uchungechunge lwe-emulsion ye-EMC
3) Ububanzi bewebhu kanye nokufanisa izinqubo
- 1250mm/1040mm: Ama-blade amancane kuya kwaphakathi, ukubekwa ngesandla
- 2500mm nangaphezulu: Ama-blade amakhulu, i-layup ezenzakalelayo, ukugqagqana okuncishisiwe
Ukukhetha Ngokwengxenye: Ungafanisa Kanjani Izindawo Ezihlukene Ze-Blade?
1) Ingubo Yangaphansi Yegobolondo Langaphandle/Ingilazi

- Kunconywa: I-EMC300/450 ephansi futhi engangenisi amanzi
- Amaphuzu abalulekile: Ukumelana nokuguga okuthuthukisiwe, ingozi yokunciphisa ukuhlukaniswa kwezakhi zofuzo
Umata oqoshiwe wentambo uma uqhathaniswa nomunyeifayibhaomata beglasi: Kungani kukhethwa ama-blades?
1) Umethi Oqoshiwe Wezintambo vs. Umethi Oqhubekayo Wentambo
- Uhlaka Oluqoshiwe: Isotropic, isembozo esihle kakhulu sesikhunta, esifanele izindawo ezigobile kanye nokufakwa
- Uhlaka Oluqhubekayo: Amandla aphezulu obude obude, ukufana okuphansi kancane
- Ukuhlanganiswa Kwe-Blade: Intambo eqoshiwe yomzimba oyinhloko, indwangu eqhubekayo/eqonde ngqo yezindawo eziyinhloko ezithwala umthwalo
2) Umethi Oqoshiwe Wezintambo vs. Umethi Obhotshozwe Ngenaliti
- Omata ababhoboza ngenaliti: Amandla aphezulu, izindleko ziphezulu
- Omata abanqunyiwe: Kulula ukucutshungulwa, kuyabiza, futhi kunezinkinga ezimbalwa
- Ukukhetha: Umucu oqoshiwe uzinzile futhi uyonga ezindaweni ezingathwali umthwalo
3) Umethi Oqoshiwe Wezintambo vs. Umethi Womphezulu
- Uhlaka Lomphezulu: 30–120 g/m², ukuze kuqinisekiswe ubuhle kuphela
- Uhlaka Oluqoshiwe: Umsebenzi ophindwe kabili wokuqinisa isakhiwo + ukufana kwendawo
- Inhlanganisela: Umata ongaphezulu + umata oqoshiwe wentambo + indwangu ene-axial eminingi yenza i-layup ejwayelekile ye-blade
Indlela Yokukhetha Yezinyathelo Ezi-5
1. Cabanga Ngenqubo: Ukumnika nge-vacuum → Khetha i-emulsion ye-EMC; Ukubekelwa kwesandla → Khetha i-CMC powder
2. Cabanga Ngendawo: Izindawo/ingaphandle eligobile → 225/300g; Ukuqinisa → 450/600g; Umthwalo osindayo → 900g
3. Okucatshangelwayo nge-resin: Izinhlelo ze-Epoxy → Qinisekisa ukuhambisana kokukhulelwa; Izinhlelo zokusebenza zasemanzini → Izinhlobo ezimelana ne-hydrolysis
4. Ububanzi bewebhu: Sebenzisa ama-web abanzi ukuze unciphise ukugqagqana kanye nokukhubazeka
5. Amazinga Ekhwalithi: Ukuphambuka kwe-Grammage ≤±5%, Okuqukethwe komswakama ≤0.2%, Akukho ukuchitheka kwempuphu noma ukufutha
Izingibe Ezivamile Namasu Okugwema
- Ukugxila kuphela entengo ngaphandle kokucabangela i-binder: Ama-powder mat asetshenziswa ekufakweni angabangela ukungena okungalingani
- Ukwandisa isisindo ngokungahleliwe: Ukujiya ngokweqile kungaholela ekufakweni okungaphelele kanye nokukhubazeka kwezingqimba eziphakathi
- Ukunganaki ububanzi kanye nokugqagqana: Ukugqagqana ngokweqile kwandisa ingozi yamabhamuza kanye nezindawo ezomile
- Ukusebenzisa izinto ezifanayo ekusetshenzisweni kwasolwandle nasemhlabeni: Ukusetshenziswa kwasolwandle kudinga amazinga akhethekile okumelana ne-hydrolysis/aphansi fuzz
