PTFE anaghị arapara na eriri iko. Enweghị ọgwụgwọ elu kwesịrị ekwesị, mkpuchi PTFE na PTFE akwa okpomọkụ ga-apụ apụ dị ka sọks rụrụ arụ. Ihe nzuzo dị na ihe ndị na-emecha elu - ọgwụgwọ kemịkalụ etinyere na akwa fiberglass tupu mkpuchi.

Ndị ọrụ ndị a - nke kachasị mkpa njikọ organosilane - na-arụ ọrụ dị ka àkwà mmiri molekụla, na-ejikọta eriri iko inorganic na PTFE organic. Nhọrọ nke onye nnọchi anya, itinye uche ya na usoro ọgwụgwọ na-ekpebi ike bee, nguzogide okpomọkụ, ndụ mgbanwe, na ịrụ ọrụ dielectric.

Aokai PTFE emechaala kemịkalụ imecha elu n'ime ọtụtụ iri afọ nke mmepụta. Ntuziaka a na-akọwa ụdị ndị ọrụ isi, mmetụta ha na ihe ndị bụ isi, yana ihe kpatara ọgwụgwọ kwesịrị ekwesị na-adịghị edozi maka akwa PTFE dị elu.

Isi ngalaba nke ndị na-emecha elu elu

Tupu mkpuchi PTFE, akwa fiberglass n'ozuzu na-enweta mwepụ wax na ịgbalite elu. A na-ekewa kemịkalụ ọgwụgwọ site na ngwakọta kemịkalụ dịka n'okpuru:

Otu	Ngwaahịa a na-ahụkarị	Atụmatụ & Ngwa
Onye nnọchi anya njikọta nke Organosilane (Eji Kachasị)	Amino silane (KH-550 / A-1100); Epoxy silane (KH-560 / A-187)	Condenses site na Si-OH nwere otu hydroxyl n'elu iko fiber; Organic arụ ọrụ dị iche iche na-etolite kemịkalụ agbụ ma ọ bụ nke anụ ahụ → molekụla àkwà mmiri, n'ụzọ dị ukwuu boosting mkpuchi adhesion
Titanate Coupling Agent	Monoalkoxy & chelate titanates	Nguzogide okpomọkụ dị oke mma na usoro fluoropolymer; na-eme ka PTFE wetting na fiberglass dịkwuo mma, na-egbochi mmebi interfacial n'okpuru okpomọkụ dị elu
Ihe Nchikota Fluorinated	Perfluoroalkyl triethoxysilane	Ike elu dị ala dị ala, ndakọrịta PTFE dị elu; perfluorocarbon yinye entanglement kwalite adhesion, hydrophobicity, antifouling arụmọrụ
Ihe Nchikota Mgbagwoju Chromium	Volan (methacryloyl chromium chloride)	Ọgwụgwọ nrapado oge gboo; ewepụrụ n'ihi nchegbu gburugburu ebe obibi & imegharịgharị n'agbanyeghị mmetụta njikọ dị ịrịba ama
Inorganic Nano Sol	Silica sol, alumina sol	Na-emepụta nano-ọnụọgụ na-adịghị ike topography n'elu eriri n'elu maka n'ibu anchoring saịtị; na-ejikọtakarị ya na ndị ọrụ njikọ

Mmetụta dị na Ngwongwo Isi nke akwa akwa okpomọkụ dị elu PTFE

Ije ozi dị ka interfacial media n'etiti inorganic iko eriri na organic fluoroplastic, ọgwụgwọ gị n'ụlọnga ọkwa na nhazi na-achịkwa n'ozuzu okokụre ngwaahịa arụmọrụ.

1. Adhesion Ike & Peel Ogologo

Ogo ọgwụgwọ	Ike bee	Ụdị ọdịda
Agwọghị ya / agwọghị ya nke ọma	<2 N/cm	Mkpuchi mkpuchi, delamination mgbe mpịachi / mpịachi ma ọ bụ elu-okpomọkụ ikpughe; ndụ ọrụ mkpụmkpụ
Ngwakọta njikọ kachasị mma	4–8+ N/cm	Njikọ kemịkalụ + njikọ anụ ahụ; mkpuchi na-eguzogide peeling n'okpuru mgbanwe ugboro ugboro na thermal ujo

Mmetụta dị egwu: Ike bee bụ ihe kacha mkpa maka ndụ ike ọgwụgwụ na nguzogide delamination.

2. Okpomọkụ Nguzogide & Thermal kwụsie ike

Ndị na-ejikọta ọnụ na-eguzogide okpomọkụ dị elu (nke nwere benzene ma ọ bụ heterocyclic, dịka, ụfọdụ epoxy & acyloxy silanes) na-eguzogide 260 ° C na-aga n'ihu na elu ozugbo> 300 ° C - dakọtara ọnọdụ ọrụ PTFE.
Ihe mgbakwunye ihe ndị na-emepụta ihe na- ekpo ọkụ na-ere ọkụ na okpomọkụ dị elu → oghere interfacial, ngbanwe agba odo, mkpuchi mkpuchi.

Ngwa ngwa: Maka ngwa okpomọkụ dị elu, hụ na onye na-emecha ihe n'onwe ya kwụsiri ike, ọ bụghị naanị mkpuchi PTFE.

3. mkpuchi mkpuchi & arụmọrụ Dielectric

Mgbanwe silane Uniform na-eme ka PTFE emulsion gbasaa na wetting n'elu eriri → mkpuchi mkpuchi na-aga n'ihu na obere pinholes na microcracks → dị oke egwu maka voltaji na-agbaji na ike mkpuchi.
Ọgwụ hygroscopic ma ọ bụ ion mmetọ nke ọgwụgwọ na-ebuli ọnwụ dielectric. A nakweere silane dị ọcha maka akwa PTFE dị elu iji belata ndabichi adịghị ọcha.

4. Chemical Resistance & Moisture Barrier

Fluorinated njikọ njikọ	Njirimara hydrophobic & oleophobic → na-egbochi nnabata capillary nke mmiri na kemịkalụ corrosive → na-eme ka ịka nká na-ekpo ọkụ, acid & alkali na-eguzogide.
Inorganic nano sol	Ihe mgbochi siri ike na-echebe eriri iko pụọ na etching site na hydrofluoric acid na mgbasa ozi na-emebi emebi

5. Mgbanwe & Ịrụ ọrụ

Ihe kpatara ya	Mmetụta
Ndị nnọchite njikọ njikọta nke karịrị oke ma ọ bụ nke siri ike-otu bara ụba	Akwa siri ike, gbochie ịkwa akwa na ime ihe na-esote
Nhazi na ogologo silanes na-agbanwe agbanwe-agbụ	Na-ejigide pliability na-achụghị arụ ọrụ njikọ

Ihe ndetu bara uru: Ọnụ ọgụgụ nke onye na-emecha ihe etinyere ga-abụ nke ọma nke ọma - ntakịrị ihe na-akpata nrapanye na-adịghị mma, nke ukwuu na-ebelata mgbanwe.

Nchịkọta - Ihe kpatara ndị na-emecha ihe ndị dị n'elu ji dị oke egwu

Ngwongwo	Mmetụta ọgwụgwọ kachasị mma	Ihe si na Ogbenye/Ọ dịghị Ọgwụgwọ
Bee ike	4-8+ N/cm	<2 N/cm → delamination, na-agbapụta
Nguzogide okpomọkụ	Na-ekpo ọkụ na 260 ° C +	Oghere dị n'ihu, na-acha odo odo, na-egbuke egbuke karịa 200 ° C
Dielectric arụmọrụ	Mkpuchi na-aga n'ihu, obere pinholes	Ọnwụ dielectric dị elu, ihe egwu mmebi
Nguzogide kemịkalụ	Na-egbochi mmiri mmiri/chemical capillary wicking	Mwakpo eriri iko, ọdịda akaghi aka
Mgbanwe	Na-ejigide pliability mgbe emelitere ya	Akwa akwa, siri ike kechie

Isi ihe na-ewe: Onye na-emecha ihe dị n'elu bụ teknụzụ bụ isi maka mmepụta akwa akwa okpomọkụ PTFE. Ndị na-ahụ maka njikọta organosilane na-achị, kemịkalụ ndị a na-arụ njikọ molekụla na interface inorganic-organic iji dozie nrapagidesi ike na-adịghị mma nke PTFE na fiberglass. Ha na-ekpebi n'ụzọ doro anya ike bee, ogologo ndụ mgbanwe, nguzogide okpomọkụ, mkpuchi ọkụ, na inertness kemịkal.

Na nchịkọta , n'elu finishing gị n'ụlọnga etinye na fiberglass ákwà tupu PTFE mkpuchi bụghị a obere nkọwa – ọ bụ ntọala nke PTFE elu-okpomọkụ ákwà mma. Ndị na-ahụ maka njikọta Organosilane (amino, epoxy, fluorinated) na-emepụta àkwà mmiri dị mkpa dị n'etiti eriri iko na PTFE, na-akwalite ike peel site na <2 N / cm ruo 4-8+ N / cm. Ngwọta kwesịrị ekwesị na-emekwa ka nguzogide okpomọkụ (260 ° C+), mkpuchi mkpuchi, arụmọrụ dielectric, na nguzogide kemịkalụ.

Mgbe ị na-ahọrọ akwa PTFE maka ngwa na-achọsi ike, jụọ banyere kemịkalụ n'elu imecha - ọ na-emetụta ndụ ọrụ na ntụkwasị obi ozugbo. Zere ihe ndị a na-agwọghị ma ọ bụ nke a na-adịghị emeso ya nke ọma, nke ga-emebi n'okpuru nrụgide okpomọkụ na n'ibu.

Achọrọ akwa akwa okpomọkụ dị elu nke PTFE nwere mmecha elu kachasị mma? Aokai PTFE na-eji usoro ihe ejikọtara ọnụ dị elu maka nrapagide na ịdịte aka dị elu. Kpọtụrụ anyị ihe achọrọ ngwa gị.
