Ilaphu le-fiberglass mesh elibekwe kwi-Scrim yokuvelisa i-blade ye-turbine yomoya
Intshayelelo emfutshane yeFiberglass Laid Scrims
Le mveliso yiI-Fiberglass Layisha Scrimibekwe endaweniimveliso ye-composite blade ye-turbine yomoya— isetyenziswa njengesakhelo sokuqinisa esikhaphukhaphu nesizinzileyo ngokwemilinganiselo ngaphakathi kwe-epoxy/vinyl ester laminates kunye nezakhiwo zesandwich (umbindi + ulusu). Yenziwe ngeimisonto ye-filament yeglasi ye-E eqhubekayoibekwe tyaba ngendlela evulekileyo enemingxuma kwayezibotshelelwe ngeekhemikhali kwiindawo ezinamaqhuqhuva(PVOH / PVC / Acrylic okanye eyenziwe ngokwezifiso). Ngokungafaniyo namalaphu alukiweyo okanye amalaphu anzima e-bi-axial, i-scrim ebekwe kakuhle igcina imicu ithe tye kwaye incinci, yongeza inkxaso yokuxinana kwamacala amaninzi kuphela6.2–15.2 g/m²(kuxhomekeke kwi-mesh). Kwii-wind blades ezingama-40–100 m ubude kwaye zakhiwe kwi-multi-hour infusion okanye kwi-prepreg cycles, i-scrim isebenza njenge-umaleko ozinzileyo kumphezulu okanye phakathi kwamagqabienceda ukulawula imibimbi yendawo, imelana nokuphathwa kokuphazamiseka ngexesha lokuphumla, kwaye ihambelana nokuqina kwe-UD/carbon yokuqala ngaphandle kokongeza ubunzima obubalulekileyo.
IGadtex (Xuzhou Gadtex / Shanghai Gadtex) ibisoloko ivelisa ii-layered scrim ukusukela ngo-2018 kwaye ibonelela ngezinto ezingama-50 ezahlukeneyo; le blade-grade yakhiwe kwiqonga elifanayo nee-PVC flooring kunye nee-aluminium foil scrims zabo, kodwaubude bomqengqeleko omde (ukuya kuthi ga kwi-50,000 m)kunyeububanzi ukuya kuthi ga kwi-2,500 mmzezona zinto zibalulekileyo kubavelisi beebhleyidi abasebenzisa i-lamination eqhubekayo okanye i-layup yesandla/ezenzekelayo enkulu.
Iimpawu zeFiberglass Laid Scrims
Iimpawu zezinto ezibalaseleyo:I-scrim ineempawu ezipheleleyo eziluncedo, kubandakanya ukuqina okuphezulu, uzinzo oluhle kakhulu, ukuguquguquka, ukuncipha okuphantsi, ubude obuphantsi, ukumelana ne-alkali, ukumelana nomlilo, kunye nokumelana nokugqwala - konke oku kubalulekile kwimeko-bume ende, yangaphandle yeeblayidi zomoya.
Amandla aphezulu kunye nobunzima obuKhanyayo:Inika ukuqina okukhulu ngelixa ilula. Iinkcukacha eziqhelekileyo ezifana ne-CF12.5×12.5PH zinobunzima obumalunga ne-6.2–6.6 g/m², i-CF10×10PH imalunga ne-8–9 g/m², kwaye i-CF5×5PH imalunga ne-15.2 g/m². Olu linganiselo luphezulu lokuqina-ubunzima luyivumela ukuba yomeleze uzinzo lwesikhumba seblade kunye nokudluliselwa kokucheba phakathi kweeleya ngobunzima obuncinci.
Iinketho zeZinto eziBanzi kunye nokwenza ngokwezifiso:Ifumaneka kwiintlobo ezahlukeneyo zeentambo (iGlass, iPolyester, iCarbon, iKevlar, iNomex, njl.njl.), ukwakhiwa kweemesh (isikwere, i-tri-directional), iipateni (iintambo ezi-0.8–3/cm), kunye nee-bonding agents (iPVOH, iPVC, iAcrylic, ezenziwe ngokwezifiso). Ifomathi ye-long roll (ukuya kuthi ga kwi-50,000 m) ixhasa iinkqubo ezisebenzayo, eziqhubekayo zokubeka okanye zokufaka iintambo.

Isicelo seFiberglass Laid Scrims
Ukusetyenziswa okuPhambili: Ukuqinisekiswa kweeComposites ze-Wind Turbine Blade
Isicelo esiphambili sale scrim ye-fiberglass ebekwe njengeumaleko ozinzileyo olulangaphakathi kwe-composite stack yeblade — phakathi kwe-gel coat/surface veil kunye ne-primary UD/carbon reinforcement, okanye njenge-interleaf kwi-sandwich construction ene-PVC/PET/balsa core. Ifakwe kwi-blade structure ukuze:
Iindawo eziLawulayo ezibhityileyo nezityebileyo kwiResin
Umgangatho wePVC wenziwe kakhulu ngePVC, kunye nezinye izinto eziyimfuneko ngexesha lokwenziwa. Wenziwa ngokulinganisa, inkqubela yokukhupha okanye enye inkqubela yokwenziwa, wahlulwe waba yiPVC Sheet Floor kunye nePVC Roller Floor. Ngoku bonke abavelisi abakhulu basekhaya nabangaphandle bawusebenzisa njengomaleko wokuqinisa ukuthintela ukudibana okanye ukudumba phakathi kweziqwenga, okubangelwa kukwanda kobushushu kunye nokuxinana kwezinto.
Zinzisa izikhumba zeSandwich kunye noQhagamshelwano oluPhambili
Yongeza umaleko we-"anchor" ye-GSM ephantsi ophucula ukudluliselwa kwe-shear phakathi kwe-foam/balsa core kunye nezikhumba ze-GFRP ngaphandle kokongeza ubunzima obubalulekileyo — okubalulekileyo ekuvalekeni kwe-trailing-edge kunye notshintsho lwe-web-flange.
Nciphisa ukuphambuka kweLayup kunye nomonakalo wokuphatha
Ukumelana nokukrazula kwe-scrim kunye nozinzo olunobukhulu kunceda ukubekwa kwe-layups eyomileyo okanye yesigaba se-B kuhlale kumile ngexesha lokubekwa, ukufakwa kwe-vacuum bagging, kunye nokuthutha ngaphakathi kwi-mold, kunciphisa ukulahlwa kunye nokulungiswa kwakhona.
Izicelo zeSibini
Ngenxa yeempawu zayo zokuqinisa eziguquguqukayo kunye noyilo oluvulekileyo lwe-mesh, le scrim ye-fiberglass ebekwe nayo isetyenziswa kakhulu kwezinye iindawo zoshishino ezininzi:
I-Aluminium Foil Composite
Isetyenziswa njengomaleko wokuqinisa izinto zokwambathisa nokwakha, nto leyo ephucula ukusebenza kakuhle kwemveliso kunye nembonakalo yemveliso egqityiweyo.
Umgangatho wePVC
Isebenza njengomaleko obalulekileyo wokuzinzisa ukumelana nokwanda kobushushu kunye nokuxinana kwezinto zomgangatho, ithintela ukwahlukana okanye ukudumba kwamalungu.
Ukuqinisa kwiintlobo ngeentlobo zeengubo ezingalukwanga
Isetyenziswa kwizinto ezifana nethishu yefiberglass, iimathi zepolyester, kunye neewipes ukuze yonyuse amandla okutsalwa ngokongeza ubunzima obuncinci.
