Yuav Ua Li Cas Nto Kho Cov Txheej Txheem Hloov Kho Cov Qauv Nto ntawm PTFE High-Temperature Cloth

PTFE high-temperature daim ntaub yog khoom plig rau nws cov tsis-stick, kub-resistant, thiab anti-corrosion zog. Tab sis tib lub ultra-smooth, qis-nto-zog, chemically inert nto uas ua rau nws zoo tagnrho rau kev tso tawm daim ntawv thov kuj ua rau nws yuav luag tsis yooj yim sua rau daim ntawv cog lus, luam tawm, los yog laminate.

Cov tshuaj yog kev kho deg - engineering ob qho tib si microstructure thiab tshuaj lom neeg muaj pes tsawg leeg ntawm PTFE nto los hloov nws los ntawm non-bondable rau bondable.

Aokai PTFE muab PTFE daim ntaub nrog ntau yam kev kho deg. Phau ntawv qhia no piav qhia txog plaub txoj hauv kev - tshuaj etching, kho plasma, kho corona, thiab kev kho laser - thiab yuav ua li cas txhua tus hloov kho lub cev thiab tshuaj.

Tshuaj Etching (Sodium-Naphthalene Solution Treatment)

Txoj kev kho ntub dej no muab cov txiaj ntsig ntev tshaj plaws thiab pom cov ntawv thov dav tshaj plaws rau PTFE bonding.

1. Kev hloov kho lub cev

Cov tshuaj sodium-naphthalene complex etches PTFE nto los ntawm stripping tawm fluorine atoms los ntawm txheej saum npoo. Lub ntsej muag daim iav-nplaum yog etched nrog suav tsis txheeb micron- rau nanoscale honeycomb- lossis coral-zoo li lub qhov thiab kab noj hniav. Qhov kev ntxhib los mos no ua rau qhov loj ntawm thaj chaw tshwj xeeb thiab tsim cov ntsiab lus sib txuas ntawm cov khoom sib txuas rau cov nplaum.

2. Kev hloov kho cov qauv tshuaj

Qhov no yog qhov kev hloov pauv tseem ceeb. Muaj zog txo sodium rho tawm fluorine atoms los ntawm PTFE carbon qaum, tawm hauv unsaturated carbon chains thiab dawb radicals. Cov chaw ua haujlwm no txuas ntxiv ua rau cov dej noo thiab cov pa oxygen hauv cov huab cua puag ncig lossis kev daws teeb meem, qhia cov pawg ua haujlwm hauv ncov qaumteb qabteb suav nrog carbonyl (C = O), hydroxyl (-OH), thiab carboxyl (-COOH) . Lub caij no, cov ntsiab lus ntawm cov pa roj carbon monoxide nce thiab cov txheej txheem kho tau hloov xim av lossis xim av-dub.

3. Qhov tshwm sim

Lub quasi-carbonized active txheej yog tsim. Nto lub zog nce los ntawm qis dua 20 dyn / cm rau PTFE ntshiab tsis kho mus rau saum toj 40-50 dyn / cm , uas txawm enables kev sib txuas ncaj qha nrog dej-raws li adhesives. Qhov kev hloov kho cov qauv no yog qhov ruaj khov . Txawm li cas los xij, txheej txheej kho tsuas yog ob peb microns nyias thiab yuav tsum tau ceev faj tiv thaiv.

Kev Kho Mob Plasma

Feem ntau siv rau kev ua haujlwm ib nrab lossis hauv-kab, kev kho ntshav plasma yog cais rau hauv lub tshuab nqus tsev plasma thiab atmospheric-pressure plasma.

1. Kev hloov kho lub cev

Cov khoom siv hluav taws xob siab (electrons, ions, dawb radicals) tsis tu ncua foob pob PTFE nto thiab ua rau cov teebmeem sputter-etching. Ib qho ultra-fine nanoscale roughened kev ntxhib los mos yog sculpted rau saum npoo; cov txheej txheem ciam teb tsis muaj zog raug tshem tawm yam tsis muaj kev puas tsuaj rau lub hauv paus fiberglass substrate. Microscopically, crystalline bulk-structured nto hloov mus rau hauv lub xeev amorphous micro-roughened.

2. Kev hloov kho cov qauv tshuaj

Cov txheej txheem roj txiav txim siab cov pab pawg ua haujlwm kawg:

• Inert gas kev kho mob (xws li, argon): tawg CF daim ntawv cog lus los tsim cov dawb radicals rau tom qab grafting ntawm pawg polar

• Reactive gases (oxygen, ammonia): ncaj qha graft hydroxyl, carbonyl, thiab amino pawg mus rau molecular chains

3. Qhov tshwm sim

Ib qho huv, ntub dej heev nano-roughened nto yog tau. Kev sib txuas-txhim kho cov nyhuv degrades dhau lub sijhawm , yog li lamination yuav tsum tau ua tiav tom qab kev kho ntshav plasma. Nws qhov txiaj ntsig tseem ceeb yog cov txheej txheem hloov kho ultra-nplua, uas nyuam qhuav hloov tag nrho cov khoom tuab thiab cov xim qub.

Kev kho mob Corona

Cov txheej txheem tawm high-voltage uas ua haujlwm sai ntawm cov ntaub ntawv nyias nyias tseem raug kev txom nyem los ntawm kev ua haujlwm nrawm.

1. Kev hloov kho lub cev

High-voltage corona paug generates micro-arc flashes. Kev cuam tshuam los ntawm cov hluav taws xob hluav taws xob siab tawg ua rau PTFE molecular chains, tsim cov chaw ua haujlwm, thiab ua rau qhov ntiav ntiav, kev ntxhib los mos. Raws li kev txo qis zog thiab luv dua cov tshuaj tiv thaiv lub sijhawm piv nrog kev kho ntshav ntshav, corona tsuas yog ua rau lub qhov dej zoo li qhov roughening.

2. Kev hloov kho cov qauv tshuaj

Ozone thiab reactive oxygen hom yog tsim nyob rau hauv qhov chaw tawm. Oxidation qhia cov pab pawg hydroxyl, peroxides, thiab carbonyl pawg kom txhawb nqa lub zog saum npoo.

3. Qhov tshwm sim

Kev kho mob tsuas yog cuam tshuam rau txheej txheej nyias nyias nrog kev hloov kho cov qauv tsis ruaj khov, uas nws cov nplaum nplaum-boosting nyhuv yuav ploj mus sai. Nws yog feem ntau xa mus ua ib ntus hauv-kab adhesion-txhim txheej txheem. Rau cov ntaub ntawv tuab dua, xws li PTFE cov ntaub kub kub, kev kho mob corona feem ntau ua rau cov txiaj ntsig qis dua piv nrog kev kho cov ntshav thiab tshuaj etching.

Kev kho mob Laser

Precision deg hloov kho siv excimer-laser lossis femtosecond-laser tshuab.

1. Kev hloov kho lub cev

Photothermal thiab photochemical teebmeem precisely fabricate li niaj zaus micron-scale array qauv xws li periodic ripples, grooves, los yog micro-pillars. Cov txheej txheem tsim cov txheej txheem no tuaj yeem raug kho kom raug los tsim cov duab geometry zoo rau kev sib tshuam nrog cov nplaum.

2. Kev hloov kho cov qauv tshuaj

High-zog laser photons rhuav lub zog CF daim ntawv cog lus, ua rau lub zos defluorination thiab carbonization. Cov chaw kho mob tsim cov pob zeb zoo li cov pa roj carbon lossis graphitic carbon txheej nrog cov ntsiab lus siab oxygen. Ultraviolet excimer lasers muaj peev xwm graft active monomers ntawm ncaj qha photochemical tshuaj tsis muaj carbonization.

3. Qhov tshwm sim

Synchronous, tsom, thiab kev hloov pauv ntawm lub cev kev ntxhib los mos thiab tshuaj polarity tiav. Lub inert polymer nto yog hloov dua siab tshiab rau hauv cov pa roj carbon-oxygen-nplua nuj txheej uas tswj tau roughness thiab siab nto zog, xa high-lub zog thiab ntev kev sib raug zoo kev ua tau zoo.

Summary – Physical and Chemical Transformation

Tag nrho plaub txoj kev kho mob ua tiav ob qho kev hloov pauv tseem ceeb:

1. Kev hloov ntawm lub cev

Lub molecular-theem du inert nto yog hloov mus rau hauv roughened topography them nrog micro-nano-scale kab noj hniav, grooves, thiab coral-style protrusions, muab abundance mechanical-interlocking thauj tog rau nkoj cov ntsiab lus rau nplaum bonding.

2. Kev hloov tshuaj lom neeg

Lub zog qis uas tsim los ntawm perfluorocarbon chains (-CF₂-CF₂-) tau hloov mus rau hauv lub zog loj uas muaj cov pa oxygen- thiab nitrogen-muaj cov polar functional pawg. Qhov chaw hloov kho tuaj yeem ntub dej los ntawm cov kua nplaum tsis tu ncua thiab tsim cov ntawv cog lus hydrogen lossis txawm tias cov ntawv cog lus tshuaj nrog cov nplaum molecules.
