iindaba

Njengoko kukho umkhwa wokuya kwiiblade ezinkulu nezikude nolwandle, uzinzo, amandla, kunye nokuhambelana kwenkqubo yeenkqubo zezinto ezidityanisiweyo kumisela ngokuthe ngqo ubomi beblade kunye nokusebenza kakuhle kokuveliswa kombane. Njengesiseko esibalulekileyo sokuqinisa iishelufu zeeblade, iiweb, imiphetho ehamba phambili, imiphetho elandelelanayo, kunye nezinye izinto,imathi yentambo eqoshiweyo (CSM)iye yaba yinto eqhelekileyo yokufakelwa i-VARTM vacuum kunye nokubumba ngesandla/ukucinezela ngenxa yokufana kwayo okuhle, ukufakwa ngokukhawuleza, ukubumba okuphezulu, kunye nokubophelela okuqinileyo phakathi kwe-laminar. Ukukhetha okungalunganga komgangatho okanye ubunzima kunokubangela iingxaki ezincinci ezifana neziphene zomphezulu okanye i-resin voids ngexesha lokufakelwa, okanye ukuphazamisa kakhulu amandla olwakhiwo kunye nokusebenza kokudinwa. Eli phepha lichaza ngokucwangcisiweyo amanqaku asemgangathweni, iinkcukacha eziphambili, ingqiqo yokukhetha, kunye nokuhambelana kwesicelo kwiimathi zemicu ezinqunqiweyo ezisetyenziswa kwiiblade ze-wind turbine.

I-Strand Mat eqoshiweyoIiBlades zeTurbine zoMoya: Indawo eSiseko kunye neeMfuno eziPhambili

Iimathi ze-wind turbine ezisikiweyo zisebenzisa ngokufanayo iifayibha ze-E ezingena-alkali ezinobubanzi obuyi-9–13μm kunye nobude obusikiweyo obuyi-12–25mm, ezihlangabezana nemigangatho ye-GB/T 17470 kwaye ziyahambelana neenkqubo ze-epoxy/vinyl ester resin.

Indlela yokukhetha amanyathelo ama-5

1. Cinga ngeNkqubo: Ukufakwa kwe-vacuum → Khetha i-emulsion ye-EMC; Ukubeka isandla → Khetha umgubo we-CMC

2. Cinga ngendawo: Imiphezulu/ingaphandle egobileyo → 225/300g; Ukuqinisa → 450/600g; Ubunzima → 900g

3. Izinto ekufuneka ziqwalaselwe kwi-resin: Iinkqubo ze-Epoxy → Qinisekisa ukuhambelana kokumitha; Ukusetyenziswa kwe-marine → Iintlobo ezimelana ne-hydrolysis

4. Ububanzi bewebhu: Sebenzisa ii-wide webs kwiiblades ezinkulu ukunciphisa ukugqithana kunye neziphene

5. Imigangatho yoMgangatho: Ukuphambuka kwegrama ≤±5%, Umxholo wobumanzi ≤0.2%, Akukho kuchitheka komgubo okanye ukufutha
