Motsoako oa Phenolic Fiberglass oa Boqapi o Moholo
Selelekela sa Sehlahisoa
Motsoako oa ho bopa oa khalase ea phenolic o nang le boholo bo boholo ke motsoako oa ho bopa oa thermosetting o entsoeng ka resin ea phenolic e le thepa ea motheo, o matlafalitsoeng ka likhoele tsa khalase, 'me o entsoe ka ho kenngoa, ho kopanya le lits'ebetso tse ling. Sebopeho sa eona hangata se kenyelletsa resin ea phenolic (binder), fiber ea khalase (thepa e matlafatsang), filler ea liminerale le lintho tse ling tse eketsang (tse kang retardant ea malakabe, moemeli oa ho lokolla hlobo, jj.).
Litšobotsi tsa Tshebetso
(1) Thepa e ntle ea mechini
Matla a ho kobeha a phahameng: lihlahisoa tse ling li ka fihla ho 790 MPa (e fetang tekanyetso ea naha ≥ 450 MPa).
Khanyetso ea tšusumetso: matla a tšusumetso a nang le likheo ≥ 45 kJ/m², a loketse likarolo tse tlas'a meroalo e matla.
Ho hanyetsa mocheso: Mocheso o hanelang mocheso oa Martin ≥ 280 ℃, botsitso bo botle ba litekanyo mochesong o phahameng, bo loketse lits'ebetso tsa tikoloho tse mochesong o phahameng.
(2) Litšobotsi tsa ho thibela motlakase
Ho hanyetsa holim'a metsi: ≥1×10¹² Ω, ho hanyetsa bophahamo ba motlakase ≥1×10¹⁰ Ω-m, ho fihlela litlhoko tse phahameng tsa ho thibela ho ruruha.
Khanyetso ea Arc: lihlahisoa tse ling li na le nako ea khanyetso ea arc metsotsoana e ≥180, e loketseng likarolo tsa motlakase tse nang le motlakase o phahameng.
(3) Ho hanyetsa ts'enyeho le ho lieha ha lelakabe
Ho hanyetsa mafome: ho hanela mongobo le hlobo, ho loketse libaka tse chesang le tse mongobo kapa tse senyang lik'hemik'hale.
Sekala se thibelang malakabe: lihlahisoa tse ling li fihlile sehlopheng sa UL94 V0, ha li chese haeba ho ka cha, mosi o le tlase ebile ha li na chefo.
(4) Ho ikamahanya le maemo ha ts'ebetso
Mokhoa oa ho bopa: ho tšehetsa ho bopa ka ente, ho bopa ka phetisetso, ho bopa ka khatello le lits'ebetso tse ling, tse loketseng likarolo tse rarahaneng tsa sebopeho.
Ho fokotseha ho tlase: ho fokotseha ha ho bopa ≤ 0.15%, ho nepahala ho hoholo ha ho bopa, ho fokotsa tlhoko ea ho sebetsa kamora ho sebetsa.
Li-parameter tsa Tekheniki
Tse latelang ke tse ling tsa li-parameter tsa tekheniki tsa lihlahisoa tse tloaelehileng:
| Ntho | Sesupo |
| Botenya (g/cm³) | 1.60~1.85 |
| Matla a ho kobeha (MPa) | ≥130~790 |
| Ho hanyetsa holim'a metsi (Ω) | ≥1×10¹² |
| Ntho ea tahlehelo ea dielektri (1MHz) | ≤0.03~0.04 |
| Ho monya metsi (mg) | ≤20 |
Likopo
- Indasteri ea motlakase: Tlhahiso ea likarolo tse sireletsang mocheso tse matla haholo tse kang likhetla tsa motlakase, li-contactor, li-commutator, jj.
- Indasteri ea likoloi: e sebelisoa likarolong tsa enjene, likarolong tsa sebopeho sa 'mele, ho ntlafatsa ho hanyetsa mocheso le boima bo bobebe.
- Sefofane: dikarolo tsa sebopeho tse hanelang mocheso o phahameng, tse kang dikarolo tsa rokete.
- Lisebelisoa tsa elektroniki le tsa motlakase: likarolo tsa ho thibela motlakase tse nang le motlakase o phahameng, ntlo ea switch, ho fihlela litlhoko tsa retardant ea mollo le ts'ebetso ea motlakase.
Litlhokomelo tsa ho sebetsana le ho boloka
Mokhoa oa ho tobetsa: mocheso 150±5℃, khatello 18-20Mpa, nako 1~1.5 min/mm.
Boemo ba polokelo: Sireletsa khanyeng le mongobong, nako ea polokelo ≤ likhoeli tse 3, baka ka mocheso oa 90℃ metsotso e 2-4 kamora mongobo.
