Cov Khoom Siv Phenolic Fiberglass Molding Compound
Kev Taw Qhia Txog Khoom
Cov tshuaj phenolic iav fiber ntau yog cov tshuaj thermosetting molding compound ua los ntawm phenolic resin ua cov khoom siv hauv paus, txhawb nqa nrog cov iav fiber, thiab ua los ntawm impregnation, sib tov thiab lwm yam txheej txheem. Nws cov khoom sib xyaw feem ntau suav nrog phenolic resin (binder), iav fiber (khoom siv txhawb nqa), cov khoom siv minerals thiab lwm yam khoom ntxiv (xws li cov nplaim taws retardant, pwm tso tus neeg sawv cev, thiab lwm yam).
Cov yam ntxwv ntawm kev ua tau zoo

Kev tiv thaiv kub: Martin kub-resistant kub ≥ 280 ℃, zoo dimensional stability ntawm qhov kub siab, tsim rau cov ntawv thov kub siab.
(2) Cov khoom siv hluav taws xob rwb thaiv tsev
Kev tiv thaiv ntawm qhov chaw: ≥1 × 10¹² Ω, qhov ntim tiv thaiv ≥1 × 10¹⁰ Ω-m, kom tau raws li qhov xav tau ntawm kev rwb thaiv tsev siab.
Arc tsis kam: qee cov khoom muaj arc tsis kam lub sijhawm ≥180 vib nas this, haum rau cov khoom siv hluav taws xob siab.
(3) Kev tiv thaiv corrosion thiab nplaim taws retardancy
Kev tiv thaiv corrosion: noo noo thiab mildew resistant, haum rau kub thiab noo noo lossis tshuaj lom neeg corrosive ib puag ncig.
Qib tiv taus hluav taws: qee cov khoom tau mus txog qib UL94 V0, tsis kub hnyiab thaum muaj hluav taws, pa luam yeeb tsawg thiab tsis muaj tshuaj lom.
(4) Kev hloov pauv ua tiav
Txoj kev molding: txhawb kev txhaj tshuaj molding, hloov molding, compression molding thiab lwm yam txheej txheem, tsim rau cov khoom sib xyaw ua ke.
Qis shrinkage: molding shrinkage ≤ 0.15%, siab molding precision, txo qhov xav tau rau post-processing.
