Lesi sihloko sihlanganisa izinkomba zokusebenza ezibalulekile ze-PTFE itheyiphu yokushisa ephezulu esetshenziswa ekufakweni kwe-vacuum, ukwelashwa kokushisa kwe-vacuum nezimo ezifanayo. Izidingo ezibalulekile zihluke kakhulu ekusetshenzisweni komkhathi: ukukhipha umoya kubaluleke kakhulu (TML≤1%, CVCM≤0.1%; amamaki e-aerospace/optical adinga i-TML≤0.5%, i-CVCM≤0.01%); ukumelana nezinga lokushisa kufanele kuqinisekiswe kukho kokubili i-PTFE substrate (260°C) kanye nongqimba olunamathelayo; I-PSA ye-silicone ehlanjululwe ngokukhethekile iyadingeka ukuvimbela ukungcoliswa kwe-siloxane; amandla okubamba izinga lokushisa eliphezulu avimbela ukukhasa nokuphakamisa unqenqema; ukuhlanzeka akudingi ukuchithwa kwe-fiber kanye nokuqukethwe kwe-ionic ephansi; i-anti-static tape (i-surface resistivity 10⁶-10⁹ Ω/sq) ivimbela ukulimala kwe-ESD; ukumelana kwe-plasma kufanele kuhlolwe izinqubo ze-sputtering/PECVD; ukuncipha okushisayo okungaphansi kuka-2% kuqinisekisa ukunemba kwemaski.

Lesi sihloko siqhathanisa izinga lokushisa legumbi kanye nokuvuthwa kwezinga lokushisa eliphezulu kwe-adhesive ezwela ukucindezela kwe-silicone ye-PTFE tape. Ukuvuthwa kwezinga lokushisa eliphezulu (120-180°C) kudala amanethiwekhi aminyene axhumene anamandla okuhlangana aqinile, okuvimbela insalela enamathelayo ngemva kokuxebuka. Yakha amabhondi okunamathisela amakhemikhali anezingxenye ezingaphansi ze-PTFE ngokusebenzisa i-primer co-curing, eqeda ubungozi be-delamination. Ukuvuthwa kwezinga lokushisa eliphezulu futhi kususa ukuguquguquka kwamangqamuzana aphansi ngaphambi kokulethwa, kuvimbela ukubhamuza nokungcoliswa kukawoyela we-silicone ngesikhathi sokushisisa kokuqala.

Lo mhlahlandlela uhlanganisa ukukhetha kwetheyiphu ye-PTFE yokushisa ephezulu yokubumba umjovo kanye nezinhlelo zokusebenza zokulwa nezinti. Ukukhetha okusekelwe emazingeni okushisa: ≤260 ° C kumapulasitiki ajwayelekile (i-tape ejwayelekile ye-silicone ye-PSA, 0.13-0.18mm); I-260-300 ° C yepulasitiki yobunjiniyela bezinga eliphezulu lokushisa njenge-PC, i-PA66, i-POM (i-adhesive ye-silicone yezinga eliphezulu, i-0.18-0.25mm); 300-400°C ye-PEEK, LCP, PPS eduze nabagijimi abashisayo (itheyiphu yokunamathela ihluleka; sebenzisa indwangu ye-PTFE enganamatheli noma ifilimu ye-PFA). Ukukhetha okusekelwe ezintweni ezibonakalayo: izinto ezicashile zidinga ukukhishwa okuphezulu okuhlanzekile kwe-PTFE; izinto ezigcwele ingilazi/amaminerali zidinga itheyiphu engagugi engu-0.25mm+; izithasiselo ezonakalisayo zidinga ingcina ekwazi ukumelana namakhemikhali kanye ne-substrate eminyene; izinhlelo zokusebenza ezizwela i-static zidinga itheyiphu ye-PTFE ephikisana ne-static.

Indwangu ye-fiberglass ehlanganiswe ne-PTFE isetshenziswa kakhulu ekucubunguleni irabha ukumelana nokushisa, impahla enganamathele, nokungqubuzana okuphansi. Izicelo ezibalulekile zifaka: amalayini okukhulula amapuleti/i-vacuum vulcanization kanye nokubumba amathayi; amabhande okuthutha angagxili ezigayweni ezivulekile, amakhalenda, nemigqa yokupholisa; indwangu ye-interleave yokugcina i-rubber ephelile; ukuphathwa okukhethekile kwe-silicone ne-fluororubber; kanye namathreyi ehhavini ukuze kulungiswe emva kokwelashwa. Izinzuzo zihlanganisa ukuqeda ukunamathela kwesikhunta, ukunciphisa ukusetshenziswa kwe-ejenti yokukhululwa, ukuvimbela ukugoqwa kwama-roller, nokuqinisekisa ukuboliswa okushelelayo.

Izinga lokushisa lengilazi (Tg) lokunamatheliswa kwe-silicone elizwela ukucindezela licishe libe ngu-120°C – liphansi kakhulu kunezinto zokunamathisela ze-acrylic. Le Tg ephansi kakhulu igcina itheyiphu ye-PTFE yokushisa okuphezulu ivumelana nezimo futhi inamathela ngisho naku -70°C, ivimbela ukuqhekeka okuphukayo futhi ivumela ukunamathela okuthembekile ezinhlelweni ze-cryogenic.

Ukukhethwa kwephepha lokukhishwa noma i-substrate yefilimu kanye ne-ejenti yokukhulula kuthinta ngokuqondile ukuqina kwesitoreji nokusebenza kokuxebuka kwetheyiphu ye-PTFE yokushisa okuphezulu. Lesi sihloko siqhathanisa i-PET vs. kraft paper substrates kanye ne-silicone ngokumelene nama-ejenti okukhululwa e-fluorinated, incoma inhlanganisela efanele yokuxebuka kwezinsalela eziyiziro nokuthembeka kwesikhathi eside.
