Bulk Phenolic Fiberglass Moulding Compound
Khoom Taw Qhia
Bulk phenolic iav fiber ntau molding compound yog ib qho thermosetting molding compound ua los ntawm phenolic resin ua cov khoom siv hauv paus, ntxiv nrog cov iav fibers, thiab ua los ntawm impregnation, sib tov thiab lwm yam txheej txheem. Nws muaj pes tsawg leeg feem ntau suav nrog phenolic resin (binder), iav fiber ntau (cov khoom siv ntxiv), ntxhia muab tub lim thiab lwm yam khoom ntxiv (xws li nplaim hluav taws kub, pwm tso tawm tus neeg sawv cev, thiab lwm yam).
Cov yam ntxwv ua haujlwm
(1) Zoo heev mechanical zog
Lub zog khoov siab: qee yam khoom tuaj yeem ncav cuag 790 MPa (ntau tshaj lub teb chaws tus qauv ≥ 450 MPa).
Impact resistance: notched cuam tshuam lub zog ≥ 45 kJ / m², haum rau qhov chaw uas muaj dynamic loads.
Thaum tshav kub kub tsis kam: Martin tshav kub-resistant kub ≥ 280 ℃, zoo seem stability ntawm kub kub, haum rau high-kub ib puag ncig daim ntaub ntawv.
(2) Cov khoom hluav taws xob rwb thaiv tsev
Surface resistivity: ≥1 × 10¹² Ω, ntim resistivity ≥1 × 10¹⁰ Ω-m, kom tau raws li qhov xav tau ntawm rwb thaiv tsev siab.
Arc tsis kam: qee cov khoom muaj lub sijhawm arc tsis kam ≥180 vib nas this, haum rau cov khoom siv hluav taws xob siab.
(3) Corrosion kuj thiab nplaim retardancy
Corrosion kuj: ya raws thiab mildew resistant, haum rau kub thiab av noo los yog tshuaj corrosive ib puag ncig.
Qib nplaim hluav taws: qee yam khoom tau mus txog qib UL94 V0, tsis muaj hluav taws kub, tsis muaj pa taws thiab tsis muaj tshuaj lom.
(4) Kev hloov kho kom haum
Moulding txoj kev: txhawb kev txhaj tshuaj molding, hloov molding, compression molding thiab lwm yam txheej txheem, haum rau cov txheej txheem complex.
Tsawg shrinkage: molding shrinkage ≤ 0.15%, siab molding precision, txo qhov xav tau rau kev ua haujlwm tom qab.
