Phenolic Fiberglass Molding Tape
Sebopeho sa Boitsebiso le Tokisetso
Ribone phenolic glass fiber molding metsoako e thehoa ka ho sebelisa phenolic resin e le binder, ho kenya likhoele tsa khalase tse se nang alkali (e ka 'nang ea e-ba nako e telele kapa ea chaotically oriented), ebe e omisa le ho bōpa ho etsa ribone prepreg. Liphetoho tse ling li ka eketsoa nakong ea boitokisetso ho ntlafatsa ts'ebetso kapa thepa e itseng ea physicochemical.
Matlafatso: Likhoele tsa khalase li fana ka matla a phahameng a mochine le ho hanyetsa tšusumetso;
Resin matrix: li-resin tsa phenolic li fa thepa e hanyetsanang le mocheso oa mocheso le thepa ea ho kenya motlakase;
Li-additives: li ka kenyelletsa li-retardants tsa lelakabe, mafura, joalo-joalo, ho latela litlhoko tsa kopo.
Litšobotsi tsa Ts'ebetso
| Lipontšo tsa ts'ebetso | Lethathamo la li-parameter/libopeho |
| Thepa ea mechine | Matla a feto-fetohang ≥ 130-790 MPa, matla a ts'usumetso ≥ 45-239 kJ/m², matla a tsitsitseng ≥ 80-150 MPa |
| Ho hanyetsa mocheso | Martin mocheso ≥ 280 ℃, mocheso o phahameng o tsitsitseng |
| Thepa ea motlakase | ho hanyetsa bokaholimo ≥ 1 × 10¹² Ω, ho hanyetsa molumo ≥ 1 × 10¹⁰ Ω-m, matla a motlakase ≥ 13-17.8 MV/m |
| Ho monya metsi | ≤20 mg (ho monya metsi a tlase, a loketseng maemo a mongobo) |
| Ho honyela | ≤0.15% (botsitso bo phahameng ba dimensional) |
| Botenya | 1.60-1.85 g/cm³ (boima bo bobebe le matla a phahameng) |
Theknoloji ea ho sebetsa
1. Maemo a ho hatella:
- Mocheso: 150±5°C
- Khatello: 350±50kg/cm²
- Nako: 1-1.5 metsotso / mm botenya
2. Mokhoa oa ho etsa: lamination, compression molding, kapa low-pressure molding, e loketseng bakeng sa libopeho tse rarahaneng tsa likaroloana tsa hlobo kapa tse kang lakane.
Libaka tsa Kopo
- Motlakase oa motlakase: li-rectifiers, li-insulators tsa motlakase, joalo-joalo E loketse ka ho khetheha bakeng sa libaka tse chesang le tse mongobo;
- Likarolo tsa mochini: likarolo tsa sebopeho se matla haholo (mohlala, matlo a nang le matlo, likere), likarolo tsa enjene ea likoloi;
- Aerospace: likarolo tse bobebe, tse hanyetsanang le mocheso o phahameng (mohlala, masakaneng a ka hare ho sefofane);
- Sebaka sa kaho: litšehetso tsa lipeipi tse thibelang ho bola, litempele tsa moaho, jj.
Polokelo le Litlhokomelo
- Maemo a polokelo: E lokela ho behoa sebakeng se phodileng le se omileng ho qoba ho monya mongobo kapa ho senyeha ha mocheso; haeba e angoa ke mongobo, e lokela ho behoa ka 90 ± 5 ℃ metsotso e 2-4 pele e sebelisoa;
- Bophelo ba Shelf: e tla sebelisoa nakong ea likhoeli tse 3 ho tloha ka letsatsi la tlhahiso, ts'ebetso e hloka ho hlahlojoa hape kamora letsatsi la ho felloa ke nako;
- Thibela khatello e boima: ho thibela tšenyo ea sebopeho sa fiber.
Mohlala oa mohlala oa sehlahisoa
FX-501: Boima ba 1.60-1.85 g/cm³, Flexural matla ≥130 MPa, matla a motlakase ≥14 MV / m;
4330-1 (tataiso e bohlasoa): matla a phahameng a sireletsang likarolo tsa meralo bakeng sa libaka tse mongobo, matla a kobang ≥60 MPa.
