Magadzirirwo ePamusoro Kurapa Matanho Anochinja Iyo Yepamusoro Chimiro chePTFE Yakakwira-Tembiricha Mucheka

PTFE high-temperature jira rinokosheswa nekusaita tsvimbo, kusapisa kupisa, uye anti-corrosion properties. Asi iyo yakafanana yekupedzisira-yakatsetseka, yakaderera-pasi-simba, kemikari inert nzvimbo inoita kuti ive yakakodzera kuburitsa maapplication inoitawo kuti zvisaite kubatanidza, kudhinda, kana laminate.

Mhinduro ndeyekurapa kwepamusoro-injiniya zvese microstructure uye chemikari yenzvimbo yePTFE kuishandura kubva kune isingabatike kuenda kune inosungirirwa.

Aokai PTFE inopa PTFE jira rine akasiyana epamusoro ekurapa sarudzo. Gwaro iri rinotsanangura nzira ina dzakajairika - makemikari etching, kurapwa kweplasma, kurapwa kwecorona, uye kurapwa kwelaser - uye kuti imwe neimwe inoshandura sei pamusoro pemuviri nemakemikari.

Kemikari Etching (Sodium-Naphthalene Solution Treatment)

Iyi nzira yekunyorova yekurapa inopa yakanyanya-kureba mhedzisiro uye inoona yakakura application yePTFE bonding.

1. Kugadziriswa kwechimiro chemuviri

Iyo sodium-naphthalene yakaoma mhinduro inomisa iyo PTFE pamusoro nekubvisa maatomu efluorine kubva kumusoro-pamusoro-pamusoro. Iyo yekutanga girazi-yakapfava pamusoro yakashongedzerwa isingaverengeke micron- kusvika nanoscale muzinga- kana makomba akaita sekorari nemakomba. Uku kukwasharara kunokurisa nzvimbo chaiyo uye inoumba mechanical-interlocking anchor points for adhesives.

2. Kugadziriswa kwemakemikari

Iyi ndiyo shanduko yakakosha. Yakanyanya kudzikisa sodium inobvisa fluorine maatomu kubva kuPTFE kabhoni musana, ichisiya isina unsaturated kabhoni cheni uye mahara radicals. Aya masayiti anoshanda anowedzera kuita nehunyoro uye okisijeni mumhepo yakadzika kana mhinduro, achiunza mapoka epolar anoshanda anosanganisira carbonyl (C=O), hydroxyl (-OH), uye carboxyl (-COOH) . Zvichakadaro, pamusoro pekabhoni yemukati inokwira uye iyo yakagadziriswa layer inoshanduka yakasviba-yakasviba kana shava-dema.

3. Mhedzisiro

A quasi-carbonized active layer inoumbwa. Simba repamusoro rinokwira kubva pasi pe20 dyn/cm kune isina kurapwa yakachena PTFE kusvika pamusoro pe40-50 dyn/cm , iyo inotogonesa kubatana kwakananga nemvura-based adhesives. Uku kugadziridzwa kwechimiro kunogara zvachose . Nekudaro, iyo yakabatwa layer ingori akati wandei mamicrons akatetepa uye inoda kuchengetedzwa kwekungwarira.

Plasma Treatment

Inowanzo shandiswa kuita chikamu kana mu-mutsara kugadzirisa, kurapwa kweplasma kunorongedzerwa kuva vacuum plasma uye atmospheric-pressure plasma.

1. Kugadziriswa kwechimiro chemuviri

High-energy particles (electrons, ions, free radicals) inoramba ichibhomba pamusoro pePTFE uye inokonzera sputter-etching effects. An ultra-fine nanoscale roughened texture inovezwa pamusoro; iyo isina kusimba yemuganhu inobviswa pasina kukuvadza pasi pefiberglass substrate. Microscopically, iyo crystalline yakawanda-yakarongeka nzvimbo inoshanduka kuita amorphous micro-roughened state.

2. Kugadziriswa kwemakemikari

Process gasi inosarudza mapoka ekupedzisira anoshanda:

• Inert gasi kurapwa (semuenzaniso, argon): Inotyora CF zvisungo kuti ibudise pamusoro pemahara radicals yekutevera kubatanidzwa kwemapoka epolar.

• Reactive magasi (oxygen, ammonia): Yakananga kubatanidza hydroxyl, carbonyl, uye amino mapoka pamaketani emamorekuru.

3. Mhedzisiro

Nzvimbo yakachena, inonyorova zvakanyanya nano-roughened inowanikwa. Iyo yekubatanidza-inosimudzira mhedzisiro inodzikisira nekufamba kwenguva , saka lamination inofanira kuitwa ipapo mushure mekurapwa kweplasma. Kukodzera kwayo kukuru ndeye Ultra-yakadzika yakagadziridzwa dhizaini, iyo isinganyatso shandura ukobvu hwezvinhu uye ruvara rwepakutanga.

Corona Treatment

Iyo yakakwira-voltage discharge tekinoroji inoshanda nekukurumidza pazvinhu zvakatetepa-firimu asi ichitambura nekukurumidza kuita regression.

1. Kugadziriswa kwechimiro chemuviri

High-voltage corona discharge inogadzira micro-arc inopenya. Mhedzisiro kubva kumaerekitironi ane simba repamusoro-soro inotsemura PTFE cheni dzemamorekuru, inogadzira nzvimbo dzinoshanda, uye inoisa isina kudzika, yakavanzika rough texture. Nekuda kwekudzikira kwesimba uye kupfupika kwekuita nguva kana ichienzaniswa nekurapa kweplasma, corona inongoburitsa kushoma gomba-rakafanana nepamusoro pevhu.

2. Kugadziriswa kwemakemikari

Ozone uye reactive oxygen marudzi anogadzirwa munzvimbo dzekuburitsa. Oxidation inounza mapoka ehydroxyl, peroxides, uye mapoka ecarbonyl kusimudza simba repamusoro zvakanyanya.

3. Mhedzisiro

Mushonga wacho unongokanganisa yakanyanya kutetepa pamusoro peturu ine isina kugadzikana chimiro chekugadzirisa, iyo inonamatira-inosimudzira mhedzisiro inopera nekukurumidza. Iyo inonyanya kuisirwa seyechinguva mu-mutsara adhesion-kusimudzira maitiro. Kune dzakakora, dzakazadzwa zvinhu zvakaita sePTFE jira rinopisa-tembiricha, kurapwa kwecorona kunowanzo kuburitsa mhedzisiro yakaderera kana ichienzaniswa nekurapa kweplasma uye makemikari etching.

Laser Kurapa

Precision pamusoro pekugadzirisa uchishandisa excimer-laser kana femtosecond-laser tekinoroji.

1. Kugadziriswa kwechimiro chemuviri

Photothermal uye photochemical mhedzisiro inonyatso gadzira yakajairika micron-scale array mapatani akadai seperiodic ripples, grooves, kana micro-pillars. Aya magadzirirwo akagadzirwa ekugadzira anogona kunyatso kurongeka-kumisikidzwa kuti aumbe akakwana geometries emakanika kupindirana nemanamira.

2. Kugadziriswa kwemakemikari

High-energy laser photons inotyora yakakwirira-simba CF zvisungo, zvichikonzera defluorination yemunharaunda uye carbonization. Nzvimbo dzakarapwa dzinogadzira madhaimondi-akafanana nekabhoni kana graphitic kabhoni akaturikidzana ane yakakwira okisijeni. Ultraviolet excimer lasers inogona kubatanidza inoshanda monomers kuburikidza yakananga photochemical maitiro pasina carbonization.

3. Mhedzisiro

Synchronous, yakanangwa, uye pateni kugadziridzwa kwechimiro chemuviri uye kemikari polarity inowanikwa. Iyo inert polymer pamusoro inoshandurwa kuita kabhoni-okisijeni-yakapfuma dhizaini ine inodzoreka roughness uye yakakwirira pamusoro pesimba, ichiunza yakakwirira-simba uye inogara kwenguva refu yekubatanidza kuita.

Pfupiso - Muviri uye Kemikari Shanduko

Nzira ina dzese dzekurapa dzinowana shanduko mbiri dzakakosha:

1. Kuchinja kwomuviri

Iyo molecular-level yakatsetseka inert surface inoshandurwa kuita roughed topography yakafukidzwa ne micro-nano-scale cavities, grooves, uye coral-style protrusions, ichipa akawanda ma mechanic-interlocking anchor points for adhesive bonding.

2. Kuchinja kwemakemikari

Iyo yakaderera-energy surface yakavakwa kubva kumaketani eperfluorocarbon (-CF₂-CF₂-) inoshandurwa kuita nzvimbo ine simba rakawanda ine oxygen- uye nitrogen-ine polar functional groups. Nzvimbo yakagadziridzwa inogona kunyoroveswa neglue yakajairwa uye kuumba mahydrogen bond kana makemikari mabhondi ane adhesive molecules.

Aokai PTFE inopa PTFE jira rine makemikari etching (chisingaperi, rima pamusoro) uye kurapwa kweplasma (yakachena, inochengetedza ruvara, pfupi activation hwindo) seyakajairwa sarudzo. Laser kurapwa kunowanikwa kune akasarudzika maapplication anoda chaiwo maitiro. Bata nesu kuti tikurukure zvaunoda bonding.

Izvo zvakataurwa pamusoro pehunyanzvi zvemukati zvinopihwa ne Jiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida kudzidza zvakawanda zvakatsanangurwa, mamiriro ekushandisa uye zvigadziriso zvakagadziridzwa zvezvigadzirwa zvedu zvizere, zvinosanganisira PTFE high-temperature jira, PTFE yakakwirira-temperature adhesive tepi, PTFE high-temperature mesh bhandi, seamless kupisa-press bhandi, single-sided PTFE jira, high-temperature-resistant-fiber-cloth. taura nesu kuburikidza neruzivo rwuri pasi apa:
