Nnukwu phenolic fiberglass ịkpụzi ogige
Okwu Mmalite Ngwaahịa
Ngwakọta ihe e ji akpụzi eriri iko phenolic buru ibu bụ ihe e ji akpụzi thermosetting nke e ji phenolic resin mee dị ka ihe ndabere, nke e ji eriri iko mee ka ọ sie ike, ma mee ya site na itinye ihe n'ime ya, ịgwakọta ya na usoro ndị ọzọ. Ihe mejupụtara ya na-agụnyekarị resin phenolic (njikọ), eriri iko (ihe na-eme ka ihe sie ike), ihe na-eme ka mineral dị n'ime ya na ihe ndị ọzọ e tinyere (dịka ihe na-egbochi ire ọkụ, ihe na-ewepụta ebu, wdg).
Àgwà Arụmọrụ
(1) Njirimara igwe dị mma
Ike gbagọrọ agbagọ dị elu: ụfọdụ ngwaahịa nwere ike iru 790 MPa (karịa ọkọlọtọ mba ≥ 450 MPa).
Nguzogide mmetụta: ike mmetụta dị larịị ≥ 45 kJ/m², dabara adaba maka akụkụ ndị nwere ibu dị ike.
Nguzogide Okpomọkụ: Okpomọkụ Martin na-eguzogide okpomọkụ ≥ 280 ℃, ezigbo nkwụsi ike nha na okpomọkụ dị elu, dabara adaba maka ngwa gburugburu ebe obibi dị elu.
(2) Njirimara mkpuchi eletriki
Nguzogide elu: ≥1×10¹² Ω, nguzogide olu ≥1×10¹⁰ Ω-m, iji mezuo mkpa mkpuchi dị elu.
Nguzogide Arc: ụfọdụ ngwaahịa nwere oge nguzogide arc ≥180 sekọnd, nke dabara adaba maka ihe eletriki dị elu.
(3) Mgbochi ire ere na mbelata ire ọkụ
Mgbochi ire ere: mmiri na-eguzogide mmiri na ebu, ọ dabara adaba maka gburugburu ebe ọkụ na iru mmiri ma ọ bụ gburugburu kemịkalụ.
Ọkwa na-egbochi ire ọkụ: ụfọdụ ngwaahịa erutela ọkwa UL94 V0, anaghị ere ọkụ ma ọ bụrụ na ọkụ abịa, obere anwụrụ ọkụ na-adịghị egbu egbu.
(4) Nhazi mgbanwe
Usoro ịkpụzi: kwado ịkpụzi ntụtụ, ịkpụzi mbufe, ịkpụzi mkpakọ na usoro ndị ọzọ, dabara adaba maka akụkụ nhazi dị mgbagwoju anya.
Mbelata dị ala: Mbelata ịkpụzi ≤ 0.15%, nhazi ịkpụzi dị elu, na-ebelata mkpa maka nhazi mgbe emechara.
Usoro Nkà na ụzụ
Ihe ndị a bụ ụfọdụ paramita teknụzụ nke ngwaahịa ndị a na-ahụkarị:
| ihe | Ihe ngosi |
| Njupụta (g/cm³) | 1.60~1.85 |
| Ike ịgbagọ (MPa) | ≥130~790 |
| Nguzogide Elu (Ω) | ≥1×10¹² |
| Ihe na-efu ego nke Dielectric (1MHz) | ≤0.03~0.04 |
| Mmiri mmịpụta (mg) | ≤20 |
Ngwa
- Ụlọ ọrụ eletrọniki: Mmepụta akụkụ mkpuchi siri ike dị elu dịka shei moto, kọntaktọ, commutators, wdg.
- Ụlọ ọrụ ụgbọala: eji ya eme ihe na akụkụ injin, akụkụ nhazi ahụ, iji melite iguzogide okpomọkụ na ibu dị mfe.
- Ụgbọelu: akụkụ nhazi na-eguzogide okpomọkụ dị elu, dịka akụkụ rọketi.
- Ngwa eletrọniki na eletriki: akụkụ mkpuchi voltaji dị elu, ebe a na-agbanwe ọkụ, iji mezuo ihe achọrọ maka ihe na-egbochi ọkụ na arụmọrụ eletriki.
Ihe Ndị A Na-eme Maka Nhazi na Nchekwa
Usoro ịpị: okpomọkụ 150±5℃, nrụgide 18-20Mpa, oge 1~1.5 nkeji/mm.
Ọnọdụ nchekwa: Chebe ya pụọ na ìhè na mmiri, oge nchekwa ≤ ọnwa 3, sie ya na okpomọkụ 90℃ maka nkeji 2 ~ 4 mgbe mmiri gasịrị.
