Nnukwu phenolic Fiberglass Molding Compound
Okwu Mmalite ngwaahịa
Nnukwu phenolic iko fiber ịkpụzi ogige bụ a thermosetting ịkpụzi ogige mere nke phenolic resin dị ka isi ihe, mesikwuru na iko emep uta eri, na mere site impregnation, ịgwakọta na ndị ọzọ Filiks. Ngwakọta ya na-agụnyekarị resin phenolic (ihe nkedo), eriri iko (ihe na-eme ka ọ dị ike), ihe ntinye mineral na ihe mgbakwunye ndị ọzọ (dị ka ọkụ retardant, onye na-ahapụ ebu, wdg).
Njirimara arụmọrụ
(1) Magburu onwe n'ibu Njirimara
Ike na-ehulata dị elu: ụfọdụ ngwaahịa nwere ike iru 790 MPa (karịa ọkọlọtọ mba ≥ 450 MPa).
Nguzogide mmetụta: ike mmetụta a na-ahụ anya ≥ 45 kJ/m², dabara maka akụkụ ndị nwere ibu dị ike.
Okpomọkụ na-eguzogide: Martin okpomọkụ na-eguzogide ≥ 280 ℃, ezigbo akụkụ kwụsie ike na elu okpomọkụ, adabara elu-okpomọkụ ngwa gburugburu ebe obibi.
(2) Ihe mkpuchi ọkụ eletrik
Nguzogide elu: ≥1 × 10¹² Ω, olu resistivity ≥1 × 10¹⁰ Ω-m, iji gboo mkpa mkpuchi dị elu.
Nguzogide Arc: ụfọdụ ngwaahịa nwere oge nguzogide arc ≥180 sekọnd, dabara maka ihe eletriki eletrik dị elu.
(3) Nguzogide corrosion na ire ọkụ
Nguzogide corrosion: mmiri na mildew na-eguzogide, dabara maka gburugburu ọkụ na iru mmiri ma ọ bụ kemịkalụ na-emebi emebi.
Ọkwa ọkụ na-egbochi ọkụ: ụfọdụ ngwaahịa eruola ọkwa UL94 V0, anaghị ere ọkụ n'ihe gbasara ọkụ, obere anwụrụ ọkụ na anaghị egbu egbu.
(4) Nhazi mgbanwe
Usoro ịkpụzi: nkwado injection ịkpụzi, nyefe ịkpụzi, mkpakọ ịkpụzi na ndị ọzọ Filiks, adabara mgbagwoju structural components.
Obere shrinkage: ịkpụzi shrinkage ≤ 0.15%, nkenke ịkpụzi dị elu, na-ebelata mkpa post-processing.
Nka nka
Ndị a bụ ụfọdụ paramita teknuzu nke ngwaahịa a na-ahụkarị:
| Ihe | Ihe ngosi |
| Njupụta (g/cm³) | 1.60-1.85 |
| Ike na-ehulata (MPa) | ≥130 ~ 790 |
| Mgbochi elu elu (Ω) | ≥1×10¹² |
| Ihe kpatara ọnwụ ọkụ eletrik (1MHz) | ≤0.03-0.04 |
| Mmụba mmiri (mg) | ≤20 |
Ngwa
- Ụlọ ọrụ Electromechanical: Imepụta akụkụ mkpuchi dị elu dị ka shells moto, contactors, commutators, wdg.
- Ụlọ ọrụ ụgbọ ala: eji akụkụ engine, akụkụ nhazi ahụ, iji melite nguzogide okpomọkụ na ịdị arọ.
- Aerospace: akụkụ nhazi nke na-eguzogide okpomọkụ dị elu, dị ka akụkụ rọketi.
- Ngwa eletrọnịkị na eletriki: akụkụ mkpuchi ọkụ dị elu, ụlọ ngbanwe, iji mezuo ihe ndị a chọrọ nke ire ọkụ na ịrụ ọrụ eletrik.
Nhazi na nchekwa nchekwa
Ịpị usoro: okpomọkụ 150 ± 5 ℃, mgbali 18-20Mpa, oge 1 ~ 1.5 min / mm.
Ọnọdụ nchekwa: Chebe ọkụ na mmiri, oge nchekwa ≤ 3 ọnwa, akpọọ nkụ na 90 ℃ maka 2 ~ 4 nkeji mgbe mmiri gachara.
