Phenolic Fiberglass Molding Daim Kab Xev
Cov Khoom Siv thiab Kev Npaj
Cov tshuaj phenolic iav fiber molding compounds yog tsim los ntawm kev siv phenolic resin ua tus binder, impregnating alkali-free iav fibers (uas yuav ntev lossis chaotically oriented), thiab tom qab ntawd ziab thiab molding los ua ib daim ribbon prepreg. Lwm cov modifiers yuav raug ntxiv thaum lub sijhawm npaj kom zoo dua processability lossis cov khoom tshwj xeeb physicochemical.
Kev Txhawb Nqa: Cov iav fibers muab lub zog siab thiab kev cuam tshuam tsis kam;
Cov resin matrix: cov phenolic resins muab cov khoom siv tiv taus kub thiab hluav taws xob rwb thaiv tsev;
Cov khoom ntxiv: tej zaum yuav suav nrog cov tshuaj tiv thaiv hluav taws, cov roj nplua nyeem, thiab lwm yam, nyob ntawm seb daim ntawv thov xav tau dab tsi.
Cov yam ntxwv ntawm kev ua tau zoo
| Cov ntsuas kev ua tau zoo | Cov yam ntxwv ntawm cov parameter |
| Cov khoom siv kho tshuab | Lub zog khoov ≥ 130-790 MPa, lub zog cuam tshuam ≥ 45-239 kJ / m², lub zog tensile ≥ 80-150 MPa |
| Kev tiv thaiv kub | Martin cua sov ≥ 280 ℃, kev ua haujlwm kub siab ruaj khov |
| Cov khoom siv hluav taws xob | qhov tsis kam ntawm qhov chaw ≥ 1 × 10¹² Ω, qhov ntim tsis kam ≥ 1 × 10¹⁰ Ω-m, lub zog hluav taws xob ≥ 13-17.8 MV/m |
| Kev nqus dej | ≤20 mg (nqus dej tsawg, tsim rau cov chaw noo noo) |
| Kev ntsws | ≤0.15% (kev ruaj khov siab) |
| Qhov Ceev | 1.60-1.85 g/cm³ (hnyav thiab muaj zog) |
Kev Siv Tshuab Ua Haujlwm
1. Cov xwm txheej ceev:
- Kub: 150 ± 5 ° C
- Siab: 350 ± 50 kg / cm²
- Lub Sijhawm: 1-1.5 feeb/hli tuab
2. Txoj kev tsim: lamination, compression molding, lossis low-pressure molding, tsim rau cov duab nyuaj ntawm cov kab txaij lossis cov ntawv zoo li cov qauv.
Cov teb ntawm daim ntawv thov
- Kev rwb thaiv hluav taws xob: cov rectifiers, lub cev muaj zog insulators, thiab lwm yam. Tshwj xeeb tshaj yog haum rau qhov chaw kub thiab noo noo;
- Cov khoom siv kho tshuab: cov khoom siv muaj zog siab (piv txwv li cov tsev nyob ntawm cov kabmob, cov iav), cov khoom siv cav tsheb;
- Aerospace: cov khoom sib dua, tiv taus kub siab (piv txwv li, cov khoom siv sab hauv dav hlau);
- Kev tsim kho thaj chaw: cov yeeb nkab tiv taus corrosion, cov qauv tsev, thiab lwm yam.
Kev Khaws Cia thiab Kev Ceev Faj
- Cov xwm txheej khaws cia: Nws yuav tsum tau muab tso rau hauv qhov chaw txias thiab qhuav kom tsis txhob nqus dej noo lossis cua sov puas tsuaj; yog tias nws raug cuam tshuam los ntawm dej noo, nws yuav tsum tau ci ntawm 90 ± 5 ℃ rau 2-4 feeb ua ntej siv;
- Lub neej txee: siv tau tsis pub dhau 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 muaj kev nyuaj siab hnyav: kom tiv thaiv kev puas tsuaj rau cov qauv fiber.
Piv txwv ntawm cov qauv khoom
FX-501: Qhov Ceev 1.60-1.85 g/cm³, Lub zog khoov ≥130 MPa, Lub zog hluav taws xob ≥14 MV/m;
4330-1 (kev taw qhia tsis meej): cov khoom siv rwb thaiv tsev muaj zog rau cov chaw noo noo, lub zog khoov ≥60 MPa.
