Phenolic Motsoako oa ho Etsa BH4330-2 Sheet
Sebopeho le Tokisetso ea Lintho
Metswako ya ho bopa ya khalase ya phenolic ya ribone e bopjwa ka ho sebedisa resin ya phenolic e le binder, e kenyang difaeba tsa khalase tse se nang alkali (tse ka bang telele kapa tse shebaneng le pherekano), ebe di omiswa le ho bopjwa ho etsa ribone e tlamang. Diphetoho tse ding di ka eketswa nakong ya ho lokiswa ho ntlafatsa bokgoni ba ho sebetsa kapa thepa e itseng ya fisik'hemistri.
Matlafatso: Likhoele tsa khalase li fana ka matla a phahameng a mechini le ho hanyetsa tšusumetso;
Matrix ea resin: li-resin tsa phenolic li fa thepa khanyetso ea ho bola ha mocheso le thepa ea ho thibela motlakase;
Lintho tse eketsoang: li ka kenyelletsa lintho tse thibelang malakabe, litlolo, jj., ho latela litlhoko tsa ts'ebeliso.
Litšobotsi tsa Tshebetso
| Matšoao a tshebetso | Mefuta/litšobotsi tsa paramethara |
| Thepa ea mechini | Matla a ho tenyetseha ≥ 130-790 MPa, matla a ho thulana ≥ 45-239 kJ/m², matla a ho thapolla ≥ 80-150 MPa |
| Ho hanyetsa mocheso | Mocheso oa Martin ≥ 280 ℃, botsitso ba ts'ebetso ea mocheso o phahameng |
| Matlo a motlakase | ho hanyetsa holim'a metsi ≥ 1 × 10¹² Ω, ho hanyetsa bophahamo ba modumo ≥ 1 × 10¹⁰ Ω-m, matla a motlakase ≥ 13-17.8 MV/m |
| Ho monya metsi | ≤20 mg (ho monya metsi hanyane, ho loketse dibaka tse mongobo) |
| Ho fokotseha ha sekhahla | ≤0.15% (botsitso bo phahameng) |
| Botenya | 1.60-1.85 g/cm³ (e bobebe ebile e matla haholo) |
Theknoloji ea ho E sebetsana
1. Maemo a ho hatella:
- Mocheso: 150±5°C
- Khatello: 350±50 kg/cm²
- Nako: Botenya ba metsotso e 1-1.5/mm
2. Mokhoa oa ho theha: lamination, compression molding, kapa construction e nang le khatello e tlase, e loketseng libopeho tse rarahaneng tsa likarolo tsa sebopeho tse kang lakane kapa tse kang lakane.
Masimo a Kopo
- Ho thibela motlakase: di-rectifier, di-insulator tsa dienjene, jj. E loketse haholo dibakeng tse chesang le tse mongobo;
- Likarolo tsa mechini: likarolo tsa sebopeho tse matla haholo (mohlala, matlo a ho kenya diberiare, digiya), dikarolo tsa enjene ya dikoloi;
- Sefofane: likarolo tse bobebe, tse hanyetsanang le mocheso o phahameng (mohlala, li-bracket tsa kahare tsa lifofane);
- Tšimo ea kaho: litšehetso tsa liphaephe tse sa senyeheng ke mafome, litempele tsa kaho, jj.
Polokelo le Litlhokomelo
- Maemo a polokelo: E lokela ho beoa sebakeng se pholileng le se omileng ho qoba ho monngoa ke mongobo kapa ho senyeha ha mocheso; haeba e angoa ke mongobo, e lokela ho besoa ka mocheso oa 90±5℃ metsotso e 2-4 pele e sebelisoa;
- Nako ea ho sebetsa: e tla sebelisoa likhoeling tse 3 ho tloha ka letsatsi la tlhahiso, ts'ebetso e hloka ho hlahlojoa hape kamora letsatsi la ho fela;
- Thibela khatello e matla: ho thibela tšenyo ea sebopeho sa faeba.
Mohlala oa mohlala oa sehlahisoa
FX-501: Boima ba 1.60-1.85 g/cm³, Matla a ho kokomoha ≥130 MPa, Matla a motlakase ≥14 MV/m;
4330-1 (tsela e litšila): likarolo tsa sebopeho tse sireletsang mocheso tse matla haholo bakeng sa libaka tse mongobo, matla a kobehang a ≥60 MPa.
