V. Tsib -Txoj Kev Xaiv Kauj Ruam
1. Tshawb xyuas cov txheej txheem: Nqus infusion → Xaiv EMC emulsion; Tes layup → CMC hmoov yuav siv tau.
2. Txheeb xyuas qhov chaw: Curved nto / tsos → 225/300g; Kev txhawb zog → 450/600g; Hnyav → 900g
3. Xyuas cov resin: Epoxy system → Paub meej tias wetting tus neeg sawv cev compatibility; Marine → Hydrolysis resistant hom
4. Tshawb xyuas qhov dav: Siv dav dav rau cov hniav loj kom txo tau qhov sib tshooj thiab qhov tsis xws luag.
5. Txheeb xyuas qhov zoo: Qhov hnyav ntawm qhov sib txawv tsawg dua lossis sib npaug li ± 5%, cov ntsiab lus noo noo tsawg dua lossis sib npaug li 0.2%, tsis muaj hmoov los thiab tsis muaj fuzz.
VI. Common Misconceptions thiab Avoidances
- Tsom ntsoov rau tus nqi nkaus xwb thiab tsis quav ntsej cov ntawv khi: Cov hmoov zoo yog qhov ua rau tsis sib xws thaum siv rau hauv infusion.
- Kev nce hauv lub hauv paus hnyav arbitrarily: Ntau thickness tuaj yeem ua rau tsis txaus infusion thiab interlayer tsis xws luag.
- Tsis quav ntsej qhov dav thiab sib tshooj: Kev sib tshooj ntau dhau ua rau muaj kev pheej hmoo ntawm huab cua npuas thiab chaw qhuav. Tsim nyog rau ob qho tib si offshore thiab onshore daim ntaub ntawv: Rau cov ntawv thov offshore, hydrolysis -resistant / low-feather- tshwj xeeb qauv yog yuav tsum tau.
VII. Summary: Cua Turbine Hniav Fiberglass Chopped Strand Mat Xaiv nyob rau hauv ib kab lus
Siv 225/300g rau cov tsos thiab kev hloov pauv, thiab 450/600g rau kev txhim kho cov qauv; ua ntej EMC emulsions rau lub tshuab nqus tsev vacuum, thiab xaiv hydrolysis-tiv taus, qis- plaub- cov ntaub pua tsev tiv taus rau sab ntug dej hiav txwv; phim qhov hnyav raws li qhov chaw thiab xaiv cov nplaum raws li cov txheej txheem, ua kom muaj kev ruaj ntseg, lub zog, thiab cov txheej txheem tag nrho nyob rau hauv ib qho mus.
Cov ntaub ntawv hniav yog qhov tseem ceeb tshaj plaws. Kev xaiv kom raug tuaj yeem txhim kho cov txiaj ntsig, txo cov nqi, thiab lav lub neej qaug zog tshaj 20 xyoo. Peb pom zoo cov neeg siv khoom tsim cov npe ntawm cov qauv sib xws, qhov chaw, cov txheej txheem, thiab cov resins rau cov txheej txheem kev yuav khoom thiab kev teeb tsa, ua rau cov khoom sib xyaw ua ke txhim khu kev qha.
