FR4 Fiber Bard Composations
Bọọdụ Fiber Fiber bụ ihe a na-emekarị insulating na ngwa eletriki na ngwa ngwa, nkwukọrịta, wdg fiber na epoxy resin. Ihe ndị bụ isi na-eme bụ fiber fiber na epoxy resin. Ihe ndị a ga-ewebata ihe mejupụtara ihe mejupụtara ihe mejupụtara mkpụrụ osisi frat site na akụkụ abụọ: iko fiber na epoxy resin.
Ihe iko iko bụ ihe dị mkpa na-eme ka ọ bụrụ nke Fiberglas nke Fiberglass, nke nwere njiri mara elu, oke ike, iguzogide na nguzogide. Mpekere iko bụ ụdị fibrous ihe emere site na iko gbazee, bụ isi ihe bụ isi. Usoro nkwadebe ya gụnyere nhọrọ nke ihe iko, na-agbaze, fibrillation na usoro ọgwụgwọ. Akụkụ iko iko na-adị n'agbata micron 10 na 20 na dayameta ma nwee ike ịdị site na milimita ole na ole na iri mita n'ogologo. Na fr4 iko a na-ekesa na ụdị eriri nke eriri ma ọ bụ akwa fiber na Epoxy Reint matrix, na-arụ ọrụ nke ike na nkwado.
Epoxy resin bụ ihe matriks nke fiber bọọdụ frak, nke nwere ezigbo insulating ihe akụrụngwa, Njirimara arụ ọrụ na kemịkalụ arụ ọrụ. Epoxy Reint bụ ụdị ihe polymer nke na-emepụta site na mmeghachi omume n'etiti mmeghachi omume epoxy na ịgwọta. A na-egosipụta resins epoxy dị obere viscosity na ezigbo ọfụma, ma enwere ike ịbara ya kpamkpam ma nwee eriri iko. Na nkwadebe nke ogwe faịlịza, epoxy resin na-ejikọ eriri faioxlass ma ọ bụ akwa na mkpụrụ nke ịgwọ ọrịa. Usoro na-arị elu nke resin epoxy resin bụ usoro mmeghachi omume kemịkalụ, enwere ike idozi oge na ogo ogo ogo ya site na ịchịkwa ụdị na ọnụọgụ nke ịgwọ ọrịa.
Ihe mgbakwunye ndị ọzọ
Na mgbakwunye na iko iko na epoxy resins, enwere ike ịgbakwunye ihe ndị ọzọ AUXIARY na Opu Fiberglaslass iji mee ka Njirimara nke ihe ahụ. Dịka ọmụmaatụ, enwere ike ịgbakwunye delvers iji chịkwaa ọnya ahụ, nkụda mmụọ na ire ọkụ nke ihe ahụ. Filter nwere ike ịbụ inorganic, dị ka aluminom oxide, alydrinom hydroxide, wdg, ma ọ bụ organic, dịka nanoscale polycale polycidide. Na mgbakwunye, ihe mgbakwunye, dịka osooso, antioxidants, wdg, wdg, nwere ike itinye iji melite nhazi na ndụ ọrụ ihe ahụ.
Na nchịkọta, isi ihe nke ogwe Fracelassas bụ iko iko na ebe epoxy resins. Iko iko na-enye ike dị elu ma sie ike dị ka mgbakwunye, ebe epoxy resin na-enye ezigbo ihe akụrụngwa na nkwụsi ike nke kemịkalụ. Site na ịchịkwa ihe ndị a na usoro nhazi, Njirimara nke ogwe Fraị Fadaglasssalas na-agbanwe iji gboo mkpa nke ngwa dị iche iche.
Insutions na-egbochi ihe bụ ihe na-eme ihe na-ejikarị ihe na ụlọ ọrụ eletriki, nke a maara dị ka phenalic resin decom dere. FR4 ọ bụghị naanị nwere ezigbo insuliting, kamakwa ike nkwụsi ike, ike arụ ọrụ na nkwụsi ike, yabụ ọ ghọọla ihe nhọrọ ịchọrọ maka ọtụtụ ụlọ ọrụ.
Ihe njiri mara nke mgbochi Insumurution na-egosipụta na akụkụ ndị a: Nke mbụ, FR4 nwere ezigbo insites. Nke mbu, fr4 nwere nkwekorita ihe ojoo. N'ụlọ okpomọkụ, ọnụ ahịa mkpuchi ya nwere ike iru 10 ohm-cm, na mgbaba ọkụ ahụ dịkwa elu, nke nwere ike igbochi ihe nkiri dị iche iche na obere mkpirisi. Nke abuo, FR4 nwere nkwụsi ike ọkụ ọkụ. N'okpuru gburugburu 120 ℃, mkpuchi ya na-eguzogide uru anaghị agbanwe agbanwe, nwere ike ịnọgide na-arụ ọrụ mkpuchi na gburugburu ọnọdụ okpomọkụ. Ọzọ, FR4 nwere ezigbo ọrụ ike. O siri ike, ike dị na mbara igwe na ike mgbanwe dị elu iji nagide nrụgide anụ ahụ nke nhazi na iji.
Na mgbakwunye, FR4 nwere ezigbo mmachibido kemịkal. Ọ na-eguzogide ọgwụ, alkalis, nnu na kemịkalụ ndị ọzọ, anaghị edozi ya ngwa ngwa.
Ntugide Mmegide nwere ọtụtụ ngwa, gụnyere mpaghara ndị a:
1. Industrylọ ọrụ eletriki: A na-eji ụlọ ọrụ elektrọn: Frince ndị na-eguzogide na-eguzogide na bọọdụ sekit, akụrụngwa eletriki, akụrụngwa nkwukọrịta na ubi ndị ọzọ na ngwaahịa ngwaahịa.
2. Aerospace na mpaghara agha: FR4 na-egbochi oke arụmọrụ na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe dị mkpa na aerospace na ndị agha.
3. Industrylọ ọrụ na-egbochi: FR4 FR4 na-abawanye na-ejikarị ya n'ọtụtụ ụlọ ọrụ na-arụ ọrụ, dị ka maka njikwa ọrụ na ihe ndị ọzọ dị mkpa.
