Jiangsu Aokai New Materials, ọkachamara na-emepụta akwa akwa okpomọkụ PTFE, na-enye mmeghe zuru oke. Usoro impregnating fiberglass ákwà na PTFE mgbasa bụ isi technology ka evenly kootu na sinter polytetrafluoroethylene jidesie fiberglass mkpụrụ, akpụ mejupụtara ihe feating elu okpomọkụ iguzogide, eletriki mkpuchi na-abụghị osisi arụmọrụ. A na-etinye ngwaahịa ndị dị otú ahụ n'ọtụtụ ebe na laminates ọla kọpa dị elu, eriri na-ebufe ọkụ na-adịghị mma, ihe akpụkpọ anụ ụlọ na ubi ndị ọzọ.
Usoro ntọala zuru oke nwere usoro isi asaa dị ka ndị a:
1. Mgbochi akwa fiberglass (Dewaxing / Desizing)
Nke a bụ usoro ọgwụgwọ tupu ọgwụgwọ kacha njọ. A na-ekpuchi ihe na-emepụta ihe na-edozi ákwà (karịsịa paraffin wax, starch derivatives) na filament fiberglass n'oge a na-akpa ákwà; Mwepụ na-ezughị ezu ga-emebi njikọ dị n'etiti PTFE na eriri iko.
· Usoro ọgwụgwọ isi: ákwà na-aga n'ihu na-aga n'ihu n'ọkụ ọkụ dị elu maka nkwụsị ọkụ na 350 ~ 400 ° C, na-ekpochapụ kpamkpam na decomposing niile organic sizing agents.
· Ijikwa ihe na-esochi: A na-ajụ oyi akwa nke mebiri emebi, mgbe ụfọdụ a na-asacha ya na mmiri dị ọcha ma ọ bụ ihe mgbaze kemịkalụ iji kpochapụ ntụ fọdụrụnụ, wee kpoo ya iji nweta akwa ọcha dị ọcha dị njikere maka ime ime.
2. PTFE Emulsion Formulation
· Akụrụngwa akụrụngwa: Mgbasa PTFE gbadoro anya na ọdịnaya siri ike ọkọlọtọ nke mkpokọta 60%.
· Usoro ịgwakọta: Jiri mmiri deionized gbasasịa ngwaahịa ahụ ka ọ bụrụ ebe ebumnuche (40%-55%) dabere na ntinye resin achọrọ na viscosity impregnation. A na-agbakwunye surfactant kwesịrị ekwesị iji kwalite ịrụ ọrụ wetting na fiberglass; enwere ike itinye thickener iji dozie viscosity mgbe ọ dị mkpa.
3. Ime ime
The isi lekwasịrị bụ zuru penetration nke PTFE emulsion n'ime eriri bundles na interstices nke kpara akwa.
1. Ụzọ Dip-Squeeze (nke a na-anabatakarị): A na-eduzi akwa ahụ site na rollers imikpu ka ọ gbanye n'ụzọ zuru ezu na tank emulsion, wee gafee n'ụdị rollers squeeze. A na-achịkwa ịdị arọ mkpuchi mkpuchi site n'ịgbanwe nrụgide rola nip iji wepụ oke emulsion wee kesaa resin n'otu n'otu.
2. Dọkịta Blade mkpuchi: Emulsion na-agbasa n'elu ákwà elu site metal agụba, adabara elu-viscosity dispersions.
4. ihicha
Akwa akwa akwa na-abanye n'ime ọkụ na-ekpo ọkụ na-ekpo ọkụ na-arụ ọrụ na 100 ~ 150 ° C.
· Nzube: Jiri nwayọọ evaporate mmiri na ele mmadụ anya n'ihu surfactants, akpụ ọbụna na-abụghị tacky akọrọ film nke PTFE ahụ na eriri na-ebupụta.
Ihe njikwa okpomọkụ: Oke okpomọkụ ga-eme ngwa ngwa na-emepụta ihe nkiri dị n'elu, na-ejide mmiri dị n'ime ya nke na-eme ka ọkpụkpụ na-emepụta pinholes na blisters.
5. Sintering (Thermal ọgwụgwọ)
A na-etinye akwa a mịrị amị ozugbo n'ime ọkụ na-ekpo ọkụ na-ekpo ọkụ maka ọgwụgwọ okpomọkụ na 360 ~ 390 ° C (ruo 400 ° C maka akara ule ụfọdụ).
· Mechanism: PTFE bụ polymer thermoplastic. N'ebe okpomọkụ dị n'elu ebe mgbaze ya (327 Celsius C), ihe ndị PTFE na-agbaze, na-asọpụta ma na-apụta na-emepụta ihe nkiri na-aga n'ihu, na-enweta njikọ njikọ na nchikota na fiberglass na-ebupụta.
· Nkewa ogbo: A na-ekewa mpaghara sintering n'ime ramp kpo oku, ihe na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ mgbe niile na akụkụ dị jụụ iji kwe nkwa ngwakọta zuru oke na-enweghị mmebi ọkụ.
6. Multi-Cycle Impregnation & Sintering
Otu okirikiri impregnation-sintering na-ewepụta naanị mkpuchi dị oke mkpa nke nwere ntụpọ pinhole. Iji ruo ọkpụrụkpụ mkpuchi mkpuchi na ọdịnaya resin (dịka ọmụmaatụ, 45%-65% resin loading for high-frequency copper-clad laminate substrates), usoro impregnation → ihicha → sintering na-emegharị ugboro 2 ruo 4 ma ọ bụ karịa. Ọkpụkpụ nke ọ bụla na-ejupụta oghere eriri ma na-abawanye ọkpụrụkpụ mkpuchi, na-emecha na-akpụ mpempe akwụkwọ mgbagwoju anya na-enweghị pinhole.
7. Ọgwụgwọ-ọgwụgwọ & Winding
1. Mgbanwe ihu igwe: Mgbe ngafe ikpeazụ nke ikpeazụ gasịrị, enwere ike itinye ọgwụgwọ corona ma ọ bụ kemịkalụ sodium-naphthalene etching iji melite nrapado elu na-emebighị mkpụrụ, na-eme ka mkpuchi ọla kọpa na-esote ma ọ bụ mkpuchi nke abụọ.
2. Mkpụcha ihu na ikuku: A na-akpụcha akụkụ ákwà kwụ ọtọ, mgbe ahụ, a na-eji igwe na-ebugo merụọ ahụ nke emechara ahụ nke ọma.
3. Nyocha dị mma: Nnwale zuru oke nke ngwaahịa emechara gụnyere ibu ndabere, ọkpụrụkpụ, ike tensile, ike bee, dielectric mgbe niile na ntụpọ elu ihu.
