Usoro ihe owuwu nke PTFE dị elu nke akwa okpomọkụ: Enwere Layer Transition n'etiti mkpuchi PTFE na mkpụrụ osisi fiberglass?

Jiangsu Aokai New Materials, ọkachamara na-emepụta akwa akwa okpomọkụ PTFE, na-ewetara gị nghọta miri emi. Dị ka ihe na-arụ ọrụ nke ọma na-arụ ọrụ nke ọma, ihe mgbagwoju anya microscopic cross-section nke PTFE akwa akwa okpomọkụ dị oké mkpa maka nkwụsị okpomọkụ ya, ike peel na mgbanwe. Na mmepụta usoro nke PTFE elu-okpomọkụ ákwà, e nwere  dị mkpa mgbanwe oyi akwa n'etiti PTFE mkpuchi na fiberglass mkpụrụ. Na-enweghị nke a mgbanwe oyi akwa, integrated structural iguzosi ike n'ezi ihe nke PTFE elu-okpomọkụ ákwà enweghị ike nweta.

Site na nyocha ihe nlere anya n'ofe akụkụ, oyi akwa mgbanwe a abụghị otu ihe mejupụtara kemịkalụ, kama ọ bụ mpaghara interfacial mejupụtara nke ejiri ọtụtụ ụzọ mgbanwe anụ ahụ na kemịkal mejupụtara. A kọwara usoro nhazi na nhazi nke oyi akwa mgbanwe dịka ndị a:

1. Silane Njikọta Agent bonding Layer

Fiberglass na-adịghị agwọ ọrịa enweghị ike ijikọ ozugbo na resin PTFE. Ya mere, a ghaghị imezi akwa fiberglass na ihe ndị na-ejikọta silane na mmepụta. Otu njedebe nke onye na-ahụ maka njikọta na-emeghachi omume na otu silanol (Si-OH) n'elu fiberglass, ebe njedebe nke ọzọ nwere otu ndị na-arụ ọrụ nwere mmekọrịta dị elu ma ọ bụ mmeghachi omume na fluororesin. Na-eje ozi dị ka a kemịkalụ bonding àkwà mmiri n'etiti fiberglass skeleton na PTFE mkpuchi, a oyi akwa na-enye isi kemịkalụ anchorage maka mkpokọta structural lamination.

2. Na-ekpo ọkụ-agbaze nrapado n'etiti oyi akwa

Na cross-ngalaba chọpụtara nke elu-ọkwa PTFE elu-okpomọkụ ákwà, a gradient mgbanwe oyi akwa nwere PFA (Perfluoroalkoxy alkane) ma ọ bụ FEP (Fluorinated Ethylene Propylene) nwere ike hụrụ n'ụzọ doro anya n'etiti PTFE mkpuchi na fiberglass mkpụrụ. N'oge ikpo ọkụ dị elu, fluoroplastics ndị a na-agbaze na-arụ ọrụ dị ka nrapado na-ekpo ọkụ n'ime ime, na-abanye ma na-ekechi ùkwù fiberglass iji guzobe usoro na-aga n'ihu. Nke a dị n'etiti oyi akwa na-egbochi delamination mkpuchi n'okpuru ọnọdụ mgbagha na mgbanwe ugboro ugboro.

3. Mechanical Interlock Interface

PTFE akwa okpomọkụ akwa na-arụpụtara site multiple impregnation na mkpuchi Filiks. N'ile anya n'ihu, PTFE emulsion na-abanye n'ime pores nke nwere obere micron nke e nwetara site na warp na weft nke akwa fiberglass. Mgbe sintering na ọgwụgwọ, na siri ike PTFE resin na-etolite a akụkụ atọ n'ibu anchoring Ọdịdị na eriri ákwà. Nhazi njikọta anụ ahụ a na-enye nkwado igwe a pụrụ ịdabere na ya, na-eme ka nkwụsi ike akụkụ yana arụmọrụ mgbochi delamination na ọrụ ogologo oge.

4. Ntugharị ihe nchekwa gradient

PTFE mkpuchi na fiberglass nwere atụmatụ ọnụọgụ dị iche iche nke mgbasawanye ọkụ, nke na-ebute nrụgide dị n'ime ngwa ngwa n'okpuru usoro kpo oku na oyi. Premium PTFE elu-okpomọkụ ákwà adopts a compositional gradient Ọdịdị: ebe nso fiberglass bụ ọgaranya okpomọkụ na-eguzogide adhesives na FEP, mgbe PTFE ịdị ọcha nke nta nke nta na-abawanye n'ebe elu elu. Nhazi gradient a na-echekwa nrụgide okpomọkụ n'okpuru ọnọdụ okpomọkụ dị elu ma na-ezere mgbawa elu nke mkpuchi.

5. Substrate Pretreatment Interface

Tupu iwulite ọkwa mgbanwe ndị a dị n'elu, akwa fiberglass ga-emerịrị ihe na-ekpocha ọkụ na desizing iji wepụ ihe ndị na-edozi akwa na adịghị ọcha. Isi usoro ọgwụgwọ a na-ekpughere otu silanol na-arụ ọrụ n'elu eriri eriri, na-enye interface dị ọcha yana kemịkalụ maka ọgwụgwọ njikọ na-esote yana ntinye resin.

The cross-section Ọdịdị nke PTFE elu-okpomọkụ ákwà Nleta a zuru ezu mejupụtara usoro featured site ike bonding, gradient penetration na ọcha resin ọtọ elu . Na-erite uru site na ọkwa mgbanwe mgbanwe dị iche iche na-ejikọta site na occlusion anụ ahụ na njikọ kemịkalụ, ihe ahụ na-ejigide ihe onwunwe ntọhapụ magburu onwe ya na nguzogide corrosion nke PTFE, ebe ọ na-enweta ike ike na ike ọgwụgwụ.
