Indlela Izinqubo Zokwelapha Okungaphezulu Zisishintsha Kanjani Isakhiwo Sokuphezulu Sendwangu Ye-PTFE Yezinga Lokushisa Eliphezulu

Indwangu ye-PTFE enezinga eliphezulu lokushisa iyaziswa ngenxa yezakhiwo zayo ezingabambisi, ukumelana nokushisa, kanye nezindawo zokulwa nokugqwala. Kodwa indawo efanayo ebushelelezi, amandla aphansi, indawo engasebenzi ngamakhemikhali eyenza ifanelekele izinhlelo zokusebenza futhi yenza kucishe kungenzeki ukubopha, ukuphrinta, noma ukulayinisa.

Isixazululo ukwelapha okungaphezulu - ubunjiniyela kokubili i-microstructure kanye nokwakheka kwamakhemikhali kwendawo ye-PTFE ukuyiguqula isuke ekungeyona isibopho iye kwisibopho.

I-Aokai PTFE inikeza indwangu ye-PTFE enezinketho ezahlukene zokwelapha ezingaphezulu. Lo mhlahlandlela uchaza izindlela ezine ezijwayelekile - ukufakwa kwamakhemikhali, ukwelashwa kwe-plasma, ukwelashwa kwe-corona, nokwelashwa nge-laser - nokuthi ngayinye iluguqula kanjani ubuso ngokomzimba nangamakhemikhali.

I-Chemical Etching (Ukwelashwa Kwesixazululo se-Sodium-Naphthalene)

Le ndlela yokwelapha emanzi iletha umphumela ohlala isikhathi eside kakhulu futhi ibona uhlelo olubanzi kakhulu lwebhondi ye-PTFE.

1. Ukuguqulwa kwesakhiwo somzimba

Isixazululo esiyinkimbinkimbi ye-sodium-naphthalene sinamathisela indawo ye-PTFE ngokukhumula ama-athomu e-fluorine kusukela kungqimba olungaphezulu. Indawo yokuqala ebushelelezi yesibuko ifakwe inqwaba yezinyosi ezincane kuya ku-nanoscale- noma imigodi nemigodi emise okwekhorali. Lokhu kuqina kukhulisa kakhulu indawo ethile futhi kwakha amaphuzu okubambelela ngomshini ahlanganayo ukuze anamathele.

2. Ukuguqulwa kwesakhiwo samakhemikhali

Lolu wuguquko oluyisisekelo. I-sodium enciphisa kakhulu ikhipha ama-athomu e-fluorine kusukela ku-PTFE carbon backbone, ishiya amaketanga ekhabhoni angagcwele kanye nama-radicals amahhala. Lawa masayithi asebenzayo aphinde aphendule ngomswakama nomoya-mpilo emoyeni ozungezile noma isixazululo, ethula amaqembu asebenzayo asendaweni ezungezile afaka i-carbonyl (C=O), i-hydroxyl (-OH), ne-carboxyl (-COOH) . Ngaleso sikhathi, okuqukethwe kwekhabhoni engaphezulu kuyakhuphuka futhi isendlalelo esiphathwayo sishintshe sibe nsundu ngokumnyama noma sibe nsundu-mnyama.

3. Umphumela

Ungqimba olusebenzayo lwe-quasi-carbonized luyakhiwa. Amandla angaphezulu akhuphuka asuka ngaphansi kuka-20 dyn/cm ku-PTFE emsulwa enganakiwe aye ngaphezu kuka- 40-50 dyn/cm , okwazi ngisho nokwenza ukubopha okuqondile okunamathelayo okusekelwe emanzini. Lokhu kuguqulwa kwesakhiwo kungokwaphakade . Kodwa-ke, ungqimba olulashiwe luncane kuphela ama-microns ambalwa futhi ludinga ukuvikelwa ngokucophelela.

Ukwelashwa Kwe-Plasma

Ngokuvamile kusetshenziselwa ukucubungula ingxenye noma emgqeni, ukwelashwa kwe-plasma kuhlukaniswa ku-vacuum plasma kanye ne-plasma yomfutho womoya.

1. Ukuguqulwa kwesakhiwo somzimba

Izinhlayiya zamandla aphezulu (ama-electron, ama-ion, ama-radicals mahhala) ziqhubeka zibhomuza indawo ye-PTFE futhi zicuphe imiphumela ehlabayo. I-ultra-fine nanoscale roughened texture ibazwe phezulu; ungqimba olubuthakathaka lomngcele lususwa ngaphandle kokulimaza i-fiberglass substrate engaphansi. Ngokwe-Microscopically, i-crystalline bulk-structured surface ishintsha ibe yi-amorphous micro-roughened state.

2. Ukuguqulwa kwesakhiwo samakhemikhali

Igesi yenqubo inquma amaqembu okugcina asebenzayo:

• Ukwelashwa kwegesi ye-inert (isb, i-argon): Kwephula amabhondi e-CF ukuze kukhiqizwe ama-radicals angaphezulu ukuze kuxhunyelelwe amaqembu amhlophe.

• Amagesi asebenzayo (i-oksijeni, i-ammonia): Gxumela ngokuqondile i-hydroxyl, i-carbonyl, namaqembu e-amino kumaketanga wamangqamuzana.

3. Umphumela

Kutholakala indawo ehlanzekile, emanzi kakhulu enano-roughened. Umphumela wokuqinisa isibopho uwohloka ngokuhamba kwesikhathi , ngakho-ke ukucwiliswa kufanele kwenziwe ngokushesha ngemva kokwelashwa kwe-plasma. Ukufaneleka kwayo okukhulu ungqimba oluguquliwe olungashoni kakhulu, olungashintshi ukujiya kwempahla kanye nombala wangempela.

Ukwelashwa KweCorona

Isu lokukhipha amandla kagesi aphezulu elisebenza ngokushesha ezintweni zefilimu elincanyana nokho elinenkinga yokwehla kokusebenza okusheshayo.

1. Ukuguqulwa kwesakhiwo somzimba

Ukukhishwa kwe-corona enamandla amakhulu kukhiqiza ukukhanya kwe-micro-arc. Umthelela ovela kuma-electron anamandla aphezulu wephula amaketanga emolekyuli ye-PTFE, udale amasayithi asebenzayo, futhi unamathisele ukuthungwa okungashoni, okucashile. Ngenxa yokuncipha kwamandla kanye nesikhathi sokusabela esifushane uma kuqhathaniswa nokwelashwa kwe-plasma, i-corona ikhiqiza kuphela ukuhwaya okulinganiselwe okufana nomgodi.

2. Ukuguqulwa kwesakhiwo samakhemikhali

I-ozone kanye nezinhlobo ze-oxygen esebenzayo zikhiqizwa ezindaweni zokulahla. I-oxidation yethula amaqembu e-hydroxyl, ama-peroxides, namaqembu e-carbonyl ukuphakamisa amandla angaphezulu kakhulu.

3. Umphumela

Ukwelashwa kuthinta kuphela ungqimba olungaphezulu oluzacile kakhulu olunokuguqulwa kwesakhiwo okungazinzile, okunamandla okunamathelisa kwawo kufiphala ngokushesha. Isetshenziswa ngokuyinhloko njengenqubo yesikhashana yokukhuthaza ukunamathela emgqeni. Ngokuqina, okugcwele okugcwele njengendwangu ye-PTFE eshisa kakhulu, ukwelashwa kwe-corona ngokuvamile kuveza imiphumela ephansi uma kuqhathaniswa nokwelashwa kwe-plasma nokushumeka kwamakhemikhali.

Ukwelashwa kweLaser

Ukuguqulwa okunembayo kwendawo kusetshenziswa ubuchwepheshe be-excimer-laser noma i-femtosecond-laser.

1. Ukuguqulwa kwesakhiwo somzimba

Imiphumela ye-Photothermal ne-photochemical yenza ngokunembile amaphethini alinganayo esikali se-micron afana nama-periodic ripples, grooves, noma micro-pillars. Lezi zakhiwo ezenziwe ngobunjiniyela zingahlelwa ngokunembile ukuze zenze amajiyometri alungile ukuze kuhlanganiswe ngokunamathelayo.

2. Ukuguqulwa kwesakhiwo samakhemikhali

Ama-laser photon anamandla aphezulu aphula amabhondi e-CF aphezulu, acuphe ukuchithwa kwendawo kanye ne-carbonization. Izindawo ezilashiwe zakha izendlalelo zekhabhoni efana nedayimane noma i-graphtic carbon enokuqukethwe okuphakeme komoyampilo. Ama-lasers e-Ultraviolet excimer angaxhunyelelwa ama-monomer asebenzayo ngokusabela okuqondile kwe-photochemical ngaphandle kwe-carbonization.

3. Umphumela

Ukuguqulwa okuvumelanayo, okuhlosiwe, kanye nephethini kokuthungwa komzimba kanye ne-chemical polarity kuyafinyelelwa. Indawo ye-polymer engenzi lutho iguqulwa ibe isendlalelo esinothe nge-carbon-oxygen enobunzima obulawulekayo namandla angaphezulu angaphezulu, iletha ukusebenza kwebhondi okuqinile okuhlala isikhathi eside.

Isifinyezo - Ukuguqulwa Komzimba Namakhemikhali

Zonke izindlela zokwelashwa ezine zenza izinguquko ezimbili ezibalulekile:

1. Ukuguqulwa komzimba

Indawo engenzi lutho eshelelayo yeleveli iguqulwa ibe i-topography eqinile embozwe imigodi emincane ye-nano-scale, imifantu, nama-coral protrusions, ehlinzeka ngamaphoyinti amaningi okubambelela axhumene ngomshini ukuze kuhlanganiswe okunamathelayo.

2. Ukuguqulwa kwamakhemikhali

Indawo enamandla aphansi eyakhiwe ngamaketanga e-perfluorocarbon (-CF₂-CF₂-) iguqulwa ibe indawo enamandla amakhulu echichimayo enamaqembu asebenza nge-oxygen ne-nitrogen. Indawo eguquliwe ingamanziswa yiglue evamile futhi yakhe izibopho ze-hydrogen noma izibopho zamakhemikhali ezinama-molecule anamathelayo.

I-Aokai PTFE inikeza indwangu ye-PTFE efakwe amakhemikhali (indawo ehlala njalo, emnyama) kanye nokwelashwa kwe-plasma (ihlanzekile, igcina umbala, iwindi elifushane lokwenza kusebenze) njengezinketho ezijwayelekile. Ukwelashwa nge-laser kuyatholakala kuzinhlelo zokusebenza ezikhethekile ezidinga amaphethini anembayo. Xhumana nathi ukuze uxoxe ngezidingo zakho zebhondi.
