Phenolic Fiberglass Moulding daim kab xev
Cov khoom sib xyaw thiab kev npaj
Ribbon phenolic iav fiber ntau molding tebchaw yog tsim los ntawm kev siv phenolic resin raws li cov binder, impregnating alkali-dawb iav fibers (uas yuav ntev los yog chaotically oriented), thiab ces ziab thiab molding los tsim ib tug ribbon prepreg. Lwm cov kev hloov kho yuav raug ntxiv thaum lub sij hawm npaj los ua kom zoo tshaj plaws los yog cov khoom siv physicochemical.
Reinforcement: iav fibers muab cov neeg kho tshuab siab zog thiab cuam tshuam tsis kam;
Resin matrix: phenolic resins muab cov khoom siv hluav taws xob tiv thaiv corrosion thiab hluav taws xob rwb thaiv tsev;
Additives: tej zaum yuav muaj xws li nplaim taws, lubricants, thiab lwm yam, nyob ntawm seb yuav tsum tau thov.
Cov yam ntxwv ua haujlwm
| Performance indicators, As | Parameter ntau yam / yam ntxwv |
| Mechanical zog | Flexural zog ≥ 130-790 MPa, cuam tshuam lub zog ≥ 45-239 kJ / m², tensile zog ≥ 80-150 MPa |
| Thaum tshav kub kub kuj | Martin kub ≥ 280 ℃, siab kub ua haujlwm ruaj khov |
| Cov khoom hluav taws xob | nto resistivity ≥ 1 × 10¹² Ω, ntim resistivity ≥ 1 × 10¹⁰ Ω-m, hluav taws xob zog ≥ 13-17.8 MV / m |
| Kev nqus dej | ≤ 20 mg (kev nqus dej tsawg, haum rau qhov chaw ntub dej) |
| Kev poob qis | ≤0.15% (siab qhov ruaj khov) |
| Qhov ntom | 1.60-1.85 g / cm³ (lub teeb yuag thiab siab zog) |
Kev Siv Tshuab
1. Nias tej yam kev mob:
- Kub: 150 ± 5 ° C
- Siab: 350 ± 50 kg / cm²
- Lub sij hawm: 1-1.5 feeb / hli thickness
2. txoj kev tsim: lamination, compression molding, los yog tsawg-pressure molding, haum rau complex duab ntawm sawb los yog daim ntawv-zoo li cov yam ntxwv qhov chaw.
Daim ntawv thov teb
- Hluav taws xob rwb thaiv tsev: rectifiers, lub cev muaj zog insulators, thiab lwm yam. Tshwj xeeb tshaj yog haum rau kub thiab av noo ib puag ncig;
- Mechanical Cheebtsam: high-strength structural qhov chaw (xws li bearing vaj tse, gears), automotive engine Cheebtsam;
- Aerospace: khaub-ncaws nyias, kub-resistant qhov chaw (xws li, aircraft sab hauv brackets);
- Kev tsim kho thaj chaw: cov yeeb nkab tiv thaiv corrosion, kev tsim qauv, thiab lwm yam.
Cia thiab ceev faj
- Cia tej yam kev mob: Nws yuav tsum tau muab tso rau hauv ib tug txias thiab qhuav qhov chaw kom tsis txhob noo noo nqus los yog kub deterioration; yog tias nws cuam tshuam los ntawm cov dej noo, nws yuav tsum tau ci ntawm 90 ± 5 ℃ rau 2-4 feeb ua ntej siv;
- Lub neej txee: yuav tsum tau siv nyob rau hauv 3 lub hlis txij li hnub tsim khoom, qhov kev ua tau zoo yuav tsum tau rov kuaj dua tom qab hnub tas sij hawm;
- Txwv tsis pub hnyav: tiv thaiv kev puas tsuaj rau cov qauv fiber ntau.
Piv txwv ntawm cov khoom qauv
FX-501: Ceev 1.60-1.85 g / cm³, Flexural zog ≥130 MPa, hluav taws xob zog ≥14 MV / m;
4330-1 (kev coj tsis sib haum): siab-lub zog insulating cov qauv qhov chaw rau qhov chaw ntub dej, khoov lub zog ≥60 MPa.
