Indwangu ye-fiberglass mesh Laid Scrim yokukhiqiza i-wind turbine blade
Isingeniso Esifushane Se-Fiberglass Laid Scrims
Lo mkhiqizo u-I-Fiberglass Laid Scrimibekwe endaweniukukhiqizwa kwe-composite blade ye-turbine yomoya— isetshenziswa njengohlaka lokuqinisa olulula, oluzinzile ngokwesilinganiso ngaphakathi kwe-epoxy/vinyl ester laminates kanye nezakhiwo zesandwich (isikhumba esiyinhloko). Yenziwe ngeimicu ye-filament yengilazi eqhubekayoibekwe ngendlela evulekile ene-mesh futhieziboshwe ngamakhemikhali kuma-node(PVOH / PVC / Acrylic noma eyenziwe ngokwezifiso). Ngokungafani nezindwangu ezilukiwe noma ezisindayo ze-bi-axial, i-scrim ebekwe kahle igcina imicu iqondile futhi igobile, inezela ukwesekwa kokuthambekela okubanzi kuphela6.2–15.2 g/m²(kuye ngokuthi inetha). Kuma-wind blades angama-40-100 m ubude futhi akhiwe ngemijikelezo yokufuthwa kwamahora amaningi noma yokulungiselela, i-scrim isebenza njenge-ungqimba oluqinisa ubuso noma oluhlanganisa amaqabungaesiza ukulawula ukushwabana kwendawo, imelana nokuphathwa kokuphazamiseka ngesikhathi sokulala, futhi ihambisana nokuqina kwe-UD/carbon okuyinhloko ngaphandle kokwengeza isisindo esibalulekile.
I-Gadtex (Xuzhou Gadtex / Shanghai Gadtex) ibilokhu ikhiqiza ama-scrim abekwe phansi kusukela ngo-2018 futhi inikeza izinhlobo zezinto ezingama-50; lokhu kwakhiwe nge-blade-grade epulatifomu efanayo nama-flooring abo e-PVC kanye nama-foil e-aluminium, kodwaubude bokugoqa okude (kufika ku-50,000 m)futhiububanzi obufika ku-2,500 mmYizona ezibaluleke kakhulu kubakhiqizi bezinsika abasebenzisa i-lamination eqhubekayo noma i-layup yesandla/ezenzakalelayo enefomethi enkulu.
Izici ze-Fiberglass Laid Scrims
Izakhiwo Ezinhle Kakhulu:I-scrim inesethi ephelele yezici ezizuzisayo, okuhlanganisa ukuqina okuphezulu, ukuzinza okuhle kakhulu, ukuguquguquka, ukuncipha okuphansi, ukunwebeka okuphansi, ukumelana ne-alkali, ukumelana nomlilo, kanye nokumelana nokugqwala - konke kubalulekile endaweni ende, yangaphandle ye-wind blades.
Amandla Aphezulu Nesisindo Esilula:Inikeza ukuqina okukhulu ngenkathi ilula. Imininingwane evamile efana ne-CF12.5×12.5PH inesisindo esingaba ngu-6.2–6.6 g/m², i-CF10×10PH ingaba ngu-8–9 g/m², kanti i-CF5×5PH ingaba ngu-15.2 g/m². Lesi silinganiso samandla aphezulu kuya kwesisindo siyivumela ukuthi ithuthukise ukuzinza kwesikhumba se-blade kanye nokudluliselwa kokucheba phakathi kwezingqimba ngesisindo esincane esengeziwe.
Izinketho Ezibanzi Zokwenza Izinto Nokwenza Ngokwezifiso:Itholakala ngezinhlobo ezahlukene zentambo (iGlass, iPolyester, iCarbon, iKevlar, iNomex, njll.), ukwakhiwa kwe-mesh (Isikwele, i-tri-directional), amaphethini (0.8–3 yarns/cm), kanye nama-bonding agents (i-PVOH, i-PVC, i-Acrylic, enziwe ngokwezifiso). Ifomethi ye-long roll (kufika ku-50,000 m) isekela izinqubo ezisebenzayo, eziqhubekayo zokubeka noma zokubopha ama-blade.

Amagremu okunikezwa okuvamile angu-6.5g, 8g, 13g, 15.5g, njll.Njengoba inamandla aphezulu kanye nesisindo esincane, ingahlanganiswa ngokuphelele nanoma iyiphi into futhi ubude bomgoqo ngamunye bungaba amamitha ayi-10,000.
Isicelo se-Fiberglass Laid Scrims
Ukusetshenziswa Okuyinhloko: Ukuqinisa Ama-Composites E-Wind Turbine Blade
Isicelo esiyinhloko salesi scrim se-fiberglass esibekwe njenge-isendlalelo esilula sokuqinisangaphakathi kwenqwaba ye-blade ehlanganisiwe — phakathi kwe-gel coat/surface veil kanye ne-primary UD/carbon reinforcement, noma njenge-interleaf ekwakhiweni kwesandwich nge-PVC/PET/balsa core. Ihlanganiswe esakhiweni se-blade ukuze:
Izindawo Zokulawula Ukushwabana Komphezulu Nokucebile Nge-Resin
Iphansi le-PVC lenziwe kakhulu nge-PVC, kanye nezinye izinto zamakhemikhali ezidingekayo ngesikhathi sokukhiqiza. Likhiqizwa ngokulinganisa, inqubekela phambili yokukhipha noma enye inqubekela phambili yokukhiqiza, lihlukaniswe nge-PVC Sheet Floor kanye ne-PVC Roller Floor. Manje bonke abakhiqizi abakhulu basekhaya nabangaphandle bayisebenzisa njengengqimba yokuqinisa ukugwema ukuhlangana noma ukukhukhumala phakathi kwezingcezu, okubangelwa ukwanda kokushisa nokufinyela kwezinto.
Qinisa Izikhumba Zesandwich Nokuxhumana Okuyinhloko
Ingeza ungqimba "lwe-anchor" oluphansi lwe-GSM oluthuthukisa ukudluliselwa kwe-shear phakathi kwezikhumba ze-foam/balsa kanye ne-GFRP ngaphandle kokwengeza isisindo esibalulekile — okubalulekile ekuvalekeni kwe-trailing-edge kanye nokuguqulwa kwe-web-flange.
Nciphisa Ukuhlanekezelwa Nokuphathwa Komonakalo
Ukumelana nokudabuka kwe-scrim kanye nokuqina kobukhulu kusiza ukwakheka okomile noma kwesigaba se-B ukubamba isimo ngesikhathi sokubeka, ukufaka izikhwama ze-vacuum, kanye nokuthutha ngaphakathi kwesikhunta, kunciphisa ukulahlwa kanye nokulungiswa kabusha.
Izinhlelo Zokusebenza Zesibili
Ngenxa yezakhiwo zayo zokuqinisa eziguquguqukayo kanye nomklamo we-mesh ovulekile, le scrim ye-fiberglass ebekwe nayo isetshenziswa kabanzi kweminye imikhakha eminingi yezimboni:
I-Aluminium Foil Composite
Isetshenziswa njengesendlalelo sokuqinisa ekufakweni kokushisa kanye nokuhlanganiswa kokugoqa ukwakha, okuthuthukisa ukusebenza kahle kokukhiqiza kanye nokubukeka komkhiqizo oqediwe.
Iphansi le-PVC
Isebenza njengesendlalelo esibalulekile sokuzinza ukuze kulwisanwe nokwanda kokushisa kanye nokufinyela kwezinto zokwakha phansi, kuvimbele ukuhlukana noma ukukhukhumala kwamalunga.
Ukuqinisa Izinto Ezingafani Nezilukiwe
Kusetshenziswa ezintweni ezifana nezicubu ze-fiberglass, omata be-polyester, kanye nama-wipes ukuze kwandiswe amandla okunamathela ngokwengeza isisindo esincane.
