IiNkqubo zoNyango loMphezulu ziLulunga Njani iSakhiwo soMphezulu we-PTFE lobushushu obuphezulu

Ilaphu le-PTFE elinobushushu obuphezulu lixabiswa ngenxa yokungakhuni, ukumelana nobushushu, kunye neempawu zokuchasa umhlwa. Kodwa kwaloo mandla asezantsi-agudileyo, asezantsi-amandla, umphezulu ongasebenziyo wekhemikhali owenza ukuba ulungele ukukhutshwa kwezicelo nawo wenza ukuba kube nzima ukubopha, ukuprinta, okanye ukulalisa.

Isisombululo lunyango lomphezulu-ubunjineli zombini i-microstructure kunye nokwakheka kweekhemikhali zomphezulu we-PTFE ukuyiguqula ukusuka kwi-non-bondable ukuya kwi-bondable.

I-Aokai PTFE ibonelela ngelaphu le-PTFE ngeendlela ezahlukeneyo zonyango lomphezulu. Esi sikhokelo sichaza iindlela ezine eziqhelekileyo - ukufakwa kweekhemikhali, unyango lwe-plasma, unyango lwe-corona, kunye nonyango lwe-laser- kunye nendlela nganye eguqula ngayo umphezulu ngokwenyama kunye neekhemikhali.

Ukufakwa kweMichiza (Unyango lweSolulo yeNaphthalene yeSodium)

Le ndlela yonyango emanzi inikezela ngeyona mpembelelo yexesha elide kwaye ibona esona sicelo sibanzi se-PTFE bonding.

1. Ukuguqulwa kwesakhiwo somzimba

Isisombululo esintsonkothileyo sesodium-naphthalene sibamba umphezulu we-PTFE ngokususa iiathom zefluorine kumaleko angaphezulu komphezulu. Umphezulu wokuqala wesipili-ogudileyo uqatywe ngentaphane ye-micron- ukuya kwi-nanoscale honeycomb- okanye imingxuma emile okwe-coral kunye nemingxuma. Oku kurhabaxa kwandisa kakhulu umgangatho othile kwaye kwenze iindawo ze-ankile ezidityanisiweyo ngoomatshini zokuncamathelisa.

2. Ukuguqulwa kwesakhiwo sekhemikhali

Le yeyona nguquko ingundoqo. Ukunciphisa kakhulu i-sodium extracts ii-athomu ze-fluorine ukusuka kwi-PTFE carbon backbone, ukushiya amatyathanga ekhabhoni angaxutywanga kunye neeradicals zamahhala. Ezi ndawo zisebenzayo ziphinde ziphendule ngokufuma kunye ne-oksijeni emoyeni okanye isisombululo, ukwazisa amaqela asebenzayo e-polar kuquka i-carbonyl (C = O), i-hydroxyl (-OH), kunye ne-carboxyl (-COOH) . Ngeli xesha, umxholo wekhabhoni womphezulu uyenyuka kwaye umaleko ophathwayo ujika ube mnyama-mdaka okanye omdaka-mnyama.

3. Isiphumo

I-quasi-carbonized layer esebenzayo yenziwe. Amandla omphezulu anyuka ukusuka ngaphantsi kwe-20 dyn/cm ngenxa ye-PTFE ecocekileyo engaphathwanga ukuya ngaphezulu kwe- 40-50 dyn/cm , nto leyo eyenza ukuba ukudibanisa ngokuthe ngqo kunye ne-adhesives esekelwe emanzini. Olu hlengahlengiso lwesakhiwo lusisigxina . Nangona kunjalo, umaleko ophathwayo unama-microns ambalwa kuphela kwaye ufuna ukukhuselwa ngononophelo.

Unyango lwePlasma

Ngokuqhelekileyo isetyenziselwa ukucubungula inxalenye okanye kwi-line, unyango lwe-plasma luhlelwa kwi-vacuum plasma kunye ne-atmospheric-pressure plasma.

1. Ukuguqulwa kwesakhiwo somzimba

Amasuntswana anamandla aphezulu (i-electron, i-ion, i-radicals yamahhala) ahlala ebhobhoza umphezulu we-PTFE kwaye aqalise iziphumo ze-sputter-etching. I-ultra-fine nanoscale roughened texture is sculpted on the surface; umaleko womda obuthathaka uyasuswa ngaphandle kokonakalisa i-fiberglass substrate engaphantsi. Ngokwe-Microscopically, umphezulu wecrystalline isambuku-ubulk uguquka ube yi-amorphous micro-roughened state.

2. Ukuguqulwa kwesakhiwo sekhemikhali

Inkqubo yegesi imisela amaqela asebenzayo okugqibela:

• Unyango lwerhasi engasebenziyo (umzekelo, iargon): Uqhawula iibhondi zeCF ukuvelisa iiradicals zasimahla zokufakelwa kwamaqela epolar.

• Iirhasi ezisebenzayo (ioksijini, i-ammonia): Ngokuthe ngqo hlumela i-hydroxyl, i-carbonyl, kunye namaqela e-amino kumatyathanga emolekyuli.

3. Isiphumo

Kufunyenwe indawo ecocekileyo, emanzi kakhulu enano-roughened. Isiphumo sokuqinisa iqhina siyehla ngokuhamba kwexesha , ngoko ke i-lamination kufuneka iqhutywe kanye emva konyango lweplasma. Eyona nto ibaluleke kakhulu kuluhlu oluguquliweyo oluguquliweyo, olutshintsha kancinci ubukhulu bezinto kunye nombala wokuqala.

Unyango lweCorona

Indlela yokukhupha i-high-voltage esebenza ngokukhawuleza kwimathiriyeli yefilimu encinci kodwa inengxaki yokuhlehla ngokukhawuleza.

1. Ukuguqulwa kwesakhiwo somzimba

Ukukhutshwa kwe-corona ene-voltage ephezulu kuvelisa ukukhanya kwe-micro-arc. Impembelelo evela kwii-electron zamandla aphezulu zaphuka amatsheyina emolekyuli e-PTFE, idala iisayithi ezisebenzayo, kwaye igcina ukuthungwa okurhabaxa okunganzulwanga. Ngenxa yamandla asezantsi kunye nobude bexesha lokuphendula elifutshane xa kuthelekiswa nonyango lweplasma, i-corona ivelisa kuphela ukurhaxa komphezulu okulinganiselweyo okufana nomngxuma.

2. Ukuguqulwa kwesakhiwo sekhemikhali

Iintlobo ze-ozone kunye ne-oksijini esebenzayo ziveliswa kwiindawo zokukhupha. I-oxidation yazisa amaqela e-hydroxyl, i-peroxides, kunye namaqela e-carbonyl ukuphakamisa amandla angaphezulu kakhulu.

3. Isiphumo

Unyango luchaphazela kuphela umaleko obhityileyo womphezulu onokuguqulwa kolwakhiwo olungazinzanga, isiphumo sokuncamathelisa kwawo siphela ngokukhawuleza. Isetyenziswa ikakhulu njengenkqubo yokukhuthaza ukuncamathelisa okwethutyana kumgca. Kwizinto ezityebileyo, ezizaliswe ubushushu obuphezulu njengelaphu le-PTFE, unyango lwe-corona luvelisa iziphumo ezikumgangatho ophantsi xa kuthelekiswa nonyango lwe-plasma kunye ne-chemical etching.

Unyango lweLaser

Ukulungiswa komphezulu ochanekileyo usebenzisa i-excimer-laser okanye i-femtosecond-laser iteknoloji.

1. Ukuguqulwa kwesakhiwo somzimba

Iziphumo zefotothermal kunye neefotochemical ngokuchanekileyo zenza iipateni eziqhelekileyo zesikali se-micron ezifana ne-periodic ripples, grooves, okanye micro-pillars. Ezi zinto zenziwe ngobunjineli bobuchwephesha zinokulungiswa ngokuchanekileyo ukuze zenze iijiyometri ezifanelekileyo zokudibanisa ngoomatshini kunye nezinto ezincamathelayo.

2. Ukuguqulwa kwesakhiwo sekhemikhali

Iifotoni ze-laser ezinamandla aphezulu ziqhekeza iibhondi zeCF eziphezulu, ezibangela ukuchithwa kwendawo kunye ne-carbonization. Iindawo ezinyangweyo ziphuhlisa icarbon efana nedayimane okanye igraphic carbon layers ezinomthamo ophakamileyo weoksijini. I-Ultraviolet excimer lasers inokumilisela iimonomers ezisebenzayo ngokuphendula ngokuthe ngqo kweefotochemical reaction ngaphandle kwecarbonization.

3. Isiphumo

I-synchronous, ekujoliswe kuyo, kunye nokuguqulwa kwepateni yokuthungwa komzimba kunye ne-chemical polarity iyafezekiswa. Umphezulu we-polymer we-inert uguqulwa ube yi-carbon-oxygen-rich-rich layer with controllable roughness and high surface energy, uhambisa amandla aphezulu kunye nokusebenza kwexesha elide.

Isishwankathelo – iNguqu yoMzimba kunye neMichiza

Zonke iindlela ezine zonyango zifezekisa iinguqu ezimbini ezibalulekileyo:

1. Utshintsho lomzimba

Umphezulu wemolekyuli ogudileyo we-inert uguqulwa ube yi-topography erhabaxa egqunywe nge-micro-nano-scale cavities, grooves, kunye ne-coral-style protrusions, ebonelela ngobuninzi be-anchor edityanisiweyo ngoomatshini bokudibanisa okuncamathelayo.

2. Ukuguqulwa kweekhemikhali

Umphezulu wamandla aphantsi owenziwe ngamatyathanga e-perfluorocarbon (-CF₂-CF₂-) uguqulwa ube ngumphezulu wamandla amaninzi kunye neoksijini kunye namaqela asebenzayo epolar anenitrogen. Umphezulu oguquliweyo unokumanziswa yiglue eqhelekileyo kwaye wenze iibhondi ze-hydrogen okanye iibhondi zekhemikhali ezineemolekyuli ezincamathelayo.

I-Aokai PTFE ibonelela ngelaphu le-PTFE elinokufakwa kweekhemikhali (osisigxina, umphezulu omnyama) kunye nonyango lweplasma (ecocekileyo, igcina umbala, ifestile evulelekileyo) njengokhetho oluqhelekileyo. Unyango lweLaser luyafumaneka kwizicelo ezikhethekileyo ezifuna iipateni ezichanekileyo. Qhagamshelana nathi ukuxoxa ngeemfuno zakho zebhondi.
