Ingabe Ukwelashwa Kwe-Flame Kungatholwa Ukuze Kuguqulwe Ubuso Be-PTFE Substrates? Ukuqhathaniswa Kwemiphumela NeCorona kanye Nokwelashwa Kwe-Plasma
Incazelo ngu I-PTFE High-Temperature Fabric Manufacturers
I. Ukuba nokwenzeka Kokwelashwa Kwelangabi ku-PTFE
Ukusebenza Kwezimboni: Empeleni, ukwelashwa kwelangabi kungabona ukuguqulwa kwendawo ye-PTFE. Nokho, akuvamile ukutholwa ezimbonini, futhi umphumela wawo uphansi kakhulu kunokwelashwa nge-plasma. I-PTFE abakhiqizi bendwangu yokushisa okuphezulu abayincomi njengendlela evamile.
Izingozi Zokuphepha: I-PTFE ijwayele ukubola ngokushisa okushisayo ngaphansi kwezinga lokushisa eliphezulu lelangabi, ikhipha amagesi anobuthi obuphezulu njenge-hydrogen fluoride ne-perfluoroisobutylene, ebeka izingozi ezinkulu kubasebenzi nendawo ezungezile. Izinyathelo zokuvikela eziqinile ziyisibopho.
Umkhawulo Wokusebenza: Ngisho nangaphansi kokulawulwa okunembile, i-oxidation yelangabi ingaphakamisa kuphela amandla angaphezulu e-PTFE ukusuka ku-18 mN/m kuya ku-30–35 mN/m. Ukulimala okushisayo endaweni kwenza kalula isendlalelo somngcele esibuthakathaka, okuholela ekuthuthukisweni okulinganiselwe kokusebenza kokunamathela.
II. Ukuqhathaniswa Kwezindlela Zokusebenza Zezinqubo Ezintathu
Ukwelashwa Kwelangabi: Ngokuthembela ku-oxidation yesikhashana ephezulu yezinga lokushisa engaphezu kuka-1000 °C kusuka elangeni, ifinyelela ukushumeka kancane futhi yethule inani elincane lamaqembu aqukethe umoya-mpilo, nokho ikhombisa ukungasebenzi kahle ekuphuleni amabhondi azinzile e-C–F.
Ukwelashwa kwe-Corona: Ukukhishwa okunamandla kagesi aphezulu kukhiqiza i-ozone nomoya-mpilo osebenzayo, okuhlanganisa ukuqhuma kwamabhomu okubonakalayo ne-oxidation ethambile. Ngenxa yokuminyana kwamandla aphansi, ayinqamuki amabhondi azinzile e-C–F.
Ukwelashwa Kwe-Plasma: Izinhlayiya ezinamandla amakhulu, ama-electron nama-radicals mahhala ahlukanisa ngokuqondile amabhondi e-C-F, futhi amaqembu axhunywe e-polar afana namaqembu e-hydroxyl, i-carboxyl nama-amino ukuze kuzuzwe ukuxhunyelelwa kwamakhemikhali, kuletha ukuguqulwa okujulile kwendawo.
Amandla Aphezulu Namandla Okunamathela: I-plasma ye-oksijeni enengcindezi ephansi ingaphakamisa amandla angaphezulu kwe-PTFE aye ku-50–65 mN/m ngamandla okunamathela afinyelela ku-8–15 MPa. Ukwelashwa kwelangabi kanye ne-corona kukhulisa amandla angaphezulu ku-30-38 mN/m, futhi amandla okunamathela ngokuvamile aphansi kune-2 MPa, ikakhulukazi ehambisana nokwehluleka kobuso.
Ukufana: Ukwelashwa kwe-Plasma (ikakhulukazi emakamelweni evacuum anengcindezi ephansi) kunikeza ukwelashwa okufanayo endaweni yonke. Ukwelashwa kwe-Corona kulungele kuphela amafilimu ayisicaba futhi kudala izindawo eziyimpumputhe zezingxenye zokusebenza ze-3D. Ukwelashwa kwelangabi kubangela kalula ukushisa kwasendaweni noma ukwelashwa okunganele ezingxenyeni ezimise okuyinkimbinkimbi.
Ukuzinza Kokuguga: Izendlalelo eziguquliwe ze-Plasma zihlala zizinzile amasonto ambalwa kuya ezinyangeni, futhi ukuguqulwa kwegraft kwandisa isikhathi esivumelekile. Umphumela wokwelashwa kwelangabi ubola phakathi kwamahora ambalwa kuya ezinsukwini. Ukwelashwa kwe-Corona kulahlekelwa ukusebenza kahle phakathi kwenqwaba yemizuzu kuya emahoreni ambalwa ngenxa yokuhlenga kabusha ngokushesha kwamaketanga angaphezulu kwamangqamuzana.
IV. Ukuhlola Okuphelele Nezixazululo Ezinconyiwe
Izinga Lomphumela: Ukwelashwa Kwe-Plasma > Ukwelashwa Kwelangabi > Ukwelashwa KweCorona. Ukwelashwa kwe-Corona empeleni akusebenzi ku-PTFE. Ukwelashwa kwelangabi kungcono nje kancane kunokwelashwa kwe-corona, kuyilapho kukhona igebe ekusebenzeni kokukhiqiza uma kuqhathaniswa nokwelashwa kwe-plasma.
Ukukhethwa Kwenqubo: Ngezidingo ezithembekile zokunamathela, ukwelashwa kwe-plasma enengcindezi ephansi noma i-sodium-naphthalene chemical etching kuyisinqumo sokuqala. I-plasma yomfutho we-atmospheric ingacatshangelwa ukucutshungulwa kwefilimu esemgqeni. Ukwelashwa kwelangabi kunqunyelwe kuphela ekuhloleni kokuhlola okwedlulele lapho okokusebenza kwe-plasma kungatholakali futhi kudingeka isibopho se-PTFE, nokulawula okuqinile phezu kwezinga lokushisa kanye nokukhipha umoya. Ukwelashwa kwe-Corona akunconyelwe ukuze kusebenze i-PTFE.
Umugqa Obalulekile Wezokuphepha: Noma iyiphi inqubo yezinga lokushisa eliphezulu esetshenziswa ku-PTFE kumele ifakwe izinto zokutholwa kwegesi ye-hydrogen fluoride namanye amagesi anobuthi kanye nezinhlelo zokungenisa umoya eziphoqelelwe ukuvimbela ukunqwabelana kwemikhiqizo ebolayo enobuthi futhi kuqinisekiswe ukuphepha kokusebenza.
