Uburyo bwo Kuvura Ubuso Bwahinduye Imiterere yubuso bwimyenda ya PTFE

Imyenda ya PTFE yo mu rwego rwo hejuru ihabwa agaciro kubera imiterere yayo idafashe, irwanya ubushyuhe, kandi irwanya ruswa. Ariko ultra-yoroshye, yubuso-buke-bwimbaraga, muburyo bwa chimique inert ituma biba byiza kurekura porogaramu nabyo bituma bidashoboka guhuza, gucapa, cyangwa laminate.

Igisubizo nukuvura hejuru - injeniyeri yaba microstructure hamwe nubumara bwimiterere yubuso bwa PTFE kugirango bihindurwe bivuye kubidahuza.

Aokai PTFE itanga umwenda wa PTFE hamwe nuburyo butandukanye bwo kuvura hejuru. Aka gatabo gasobanura uburyo bune busanzwe - kuvura imiti, kuvura plasma, kuvura corona, no kuvura lazeri - nuburyo buri kimwe gihindura ubuso bwumubiri na chimique.

Gutera imiti (Sodium-Naphthalene Umuti wo gukemura)

Ubu buryo bwo kuvura butanga ingaruka ndende-ndende kandi bukabona porogaramu nini yo guhuza PTFE.

1. Guhindura imiterere yumubiri

Sodium-naphthalene igoye ikemura ikibazo cya PTFE mukuramo atome ya fluor kuva hejuru-hejuru. Ubusanzwe indorerwamo-yoroshye igizwe na micron itabarika- kugeza kuri nanoscale ubuki- cyangwa ibyobo bimeze nka korali hamwe na cavites. Uku kwaguka kwaguka cyane ubuso bwihariye kandi bugakora imashini ihuza imashini ifatika.

2. Guhindura imiterere yimiti

Iri ni ihinduka ryibanze. Sodium ikomeye cyane ikuramo atome ya fluor mumugongo wa karubone ya PTFE, hasigara iminyururu ya karubone idahagije hamwe na radicals yubusa. Izi mbuga zikora zirakomeza kwitwara hamwe nubushuhe hamwe na ogisijeni mukirere kidasanzwe cyangwa igisubizo, bikamenyekanisha amatsinda yimikorere ya polar harimo karubone (C = O), hydroxyl (-OH), na carboxyl (-COOH) . Hagati aho, karubone yo hejuru irazamuka kandi urwego rwavuwe ruhinduka umukara-umukara cyangwa umukara-umukara.

3. Ibisubizo

A Quasi-karubone ikora igaragara. Ingufu zo hejuru zirazamuka ziva munsi ya 20 dyn / cm kuri PTFE itavuwe neza igera kuri 40-50 dyn / cm , ndetse ikanafasha guhuza bitaziguye n'amazi ashingiye kumazi. Ihinduka ryimiterere rihoraho . Nyamara, urwego rwavuwe ni microne nyinshi zinanutse kandi bisaba kurindwa neza.

Umuti wa plasma

Bikunze gukoreshwa mugutunganya igice cyangwa kumurongo, kuvura plasma bishyirwa mubice bya plasma vacuum na plasma yumuvuduko wikirere.

1. Guhindura imiterere yumubiri

Ibice byinshi byingufu (electron, ion, radicals yubusa) bikomeje gutera hejuru ya PTFE kandi bigatera ingaruka ziterwa na sputter. Ultra-nziza ya nanoscale ikomye neza irashushanyije hejuru; imbibi zintege nke zavanyweho nta kwangiza fibre yububiko bwa fibre. Mikorosikopi, hejuru ya kristaline yubatswe hejuru ihinduka amorphous micro-roughened leta.

2. Guhindura imiterere yimiti

Gazi itunganya igena amatsinda yanyuma akora:

• Gutunganya gazi ya gazi (urugero, argon): Ihagarika imigozi ya CF kugirango itange radicals yubusa kubutaka nyuma yo guhuza amatsinda ya polar

• Imyuka ikora (ogisijeni, amoniya): Shira mu buryo butaziguye hydroxyl, karubone, na amine amatsinda kumurongo wa molekile

3. Ibisubizo

Ubuso busukuye, butose cyane nano-bugoye buraboneka. Ingaruka-yo kongera imbaraga igabanuka mugihe , bityo lamination igomba gukorwa nyuma yo kuvura plasma. Ibyingenzi byingenzi ni ultra-shallow yahinduwe igorofa, idahindura gusa ubunini bwibintu hamwe nibara ryumwimerere.

Umuti wa Corona

Tekinike yo gusohora amashanyarazi menshi ikora byihuse kubikoresho bya firime yoroheje ariko ikababara vuba.

1. Guhindura imiterere yumubiri

Umuvuduko mwinshi wa corona usohora utanga micro-arc flash. Ingaruka ziva kuri electroni zifite ingufu nyinshi zimenagura iminyururu ya PTFE, ikora imbuga zikora, kandi ikarenza urugero ruto, rworoshye. Bitewe ningufu nkeya hamwe nigihe gito cyo kugereranya ugereranije no kuvura plasma, corona itanga gusa umwobo muto usa nubutaka bubi.

2. Guhindura imiterere yimiti

Ubwoko bwa Ozone na reaction ya ogisijeni ikorerwa ahantu hasohokera. Oxidation itangiza amatsinda ya hydroxyl, peroxide, na karubone kugirango izamure ingufu zubutaka ku buryo bugaragara.

3. Ibisubizo

Ubuvuzi bugira ingaruka gusa kubutaka bworoshye cyane hamwe no guhindura imiterere idahindagurika, ingaruka-zifata imbaraga zishira vuba. Irakoreshwa cyane cyane nkigihe gito kumurongo wo guhuza ibikorwa. Kubikoresho byimbitse, byuzuye nka PTFE imyenda yubushyuhe bwo hejuru, kuvura corona mubusanzwe bitanga umusaruro muke ugereranije no kuvura plasma no kuvura imiti.

Kuvura Laser

Guhindura neza neza ukoresheje tekinoroji ya excimer-laser cyangwa femtosekond-laser.

1. Guhindura imiterere yumubiri

Ingaruka ya Photothermal na Photochemical ingaruka zihimbira neza micron-nini yuburyo busanzwe nkibishushanyo mbonera, ibinono, cyangwa micro-inkingi. Izi miterere yakozwe muburyo bwubukorikori irashobora guhindurwa neza kugirango igire geometrike nziza yo guhuza imashini hamwe nudusimba.

2. Guhindura imiterere yimiti

Amafoto menshi ya laser fotone asenya imbaraga nyinshi za CF, bigatuma defluorination yaho na karubone. Ahantu havuwe hatezimbere diyama isa na karubone cyangwa ibishushanyo mbonera bya karubone bifite ogisijeni nyinshi. Ultraviolet excimer laseri irashobora gushushanya monomer ikora hifashishijwe reaction ya fotokomeque idafite karubone.

3. Ibisubizo

Guhuza, intego, hamwe no guhindura imiterere yumubiri hamwe na polarite ya chimique iragerwaho. Ubuso bwa polimeri ya inert ihindurwamo karubone-ogisijeni ikungahaye cyane hamwe nububasha bushobora kugenzurwa nimbaraga zo hejuru, bigatanga imbaraga nyinshi kandi zirambye.

Incamake - Guhindura umubiri na shimi

Uburyo bune bwo kuvura bugera ku mpinduka ebyiri zifatizo:

1. Guhinduka kumubiri

Ubuso bwa molekulike buringaniye buringaniye bwahinduwe mubutaka bubi butwikiriwe na micro-nano-nini ya cavites, grooves, hamwe na korali yuburyo bwa korali, bitanga ingingo nyinshi zifatika zifatika zifatika zifatika.

2. Guhindura imiti

Ubuso buke buke bwubatswe muminyururu ya perfluorocarubone (-CF₂-CF₂-) ihindurwa hejuru yingufu nyinshi nyinshi hamwe na ogisijeni- na azote irimo amatsinda yimikorere ya polar. Ubuso bwahinduwe bushobora guhanagurwa na kole isanzwe hanyuma bigakora imigozi ya hydrogène cyangwa se imiti ihuza na molekile ifata.

Aokai PTFE itanga umwenda wa PTFE hamwe na chimique (guhoraho, hejuru yijimye) hamwe no kuvura plasma (isuku, irinda amabara, idirishya rito rya enterineti) nkuburyo busanzwe. Kuvura Laser birahari kubikorwa byihariye bisaba uburyo bwuzuye. Twandikire kugirango tuganire kubyo usabwa.

Ibikoresho bya tekinike byavuzwe haruguru bitangwa na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba ufite intego yo kwiga ibisobanuro birambuye, ibisobanuro byerekana hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, umukandara wa PTFE ufite ubushyuhe bwo hejuru, umukandara udashyushye, umukandara wa PTFE, umwenda umwe, umukandara utwara ubushyuhe hamwe nigitambaro cya fiberglass, nyamuneka twandikire ukoresheje amakuru hepfo:
