Thepi ya mahiselo yale henhla ya PTFE yina ku tiya lokunga kahle eka miseve ya ionizing. Eka 1 kGy ntsena ya gamma exposure, matimba ya tensile ya hunguteka kuya eka ~25% ya original. Yi lulamerile ntsena eka tindzhawu ta mpimo wale hansi (swakudya/ku sterilization ka swa vutshunguri <10 kGy). Eka bindzu ra nyutliya kumbe swihaha-mpfhuka swa le xibakabakeni, tirhisa polyimide kumbe PEEK ematshan’weni ya sweswo.

Eka ti tapes ta PTFE ta mahiselo yale henhla ehansi ka ku nyuperisiwa ka nkarhi woleha, substrate ya PTFE yitshama yirikarhi yinga tirhi hi ti khemikhali, kambe leyara yo namarhela hi yona ndzhawu yo tsana. Mati ya tsanisa silicone PSA; mati ya munyu ya hatlisisa ku bola. Eka tikhemikhali leti nga ni matimba, swinamarheti swa fluorosilicone kumbe perfluoropolyether – kumbe thepi ya PTFE leyi nga riki na swinamarheti – swa laveka. Ku lahlekeriwa hi matimba ya peel kuya fika eka 40% endzhaku ka 48 wa tiawara ematini.

Thepi ya PTFE ya mahiselo yale henhla leyi tirhisiwaka eka switirhisiwa swa ku khumbana ka swakudya yifanele ku tshama eka swipimelo swa mahiselo leswi hlamuseriweke: ≤260°C eka kutirhisiwa loku yaka emahlweni, ≤300°C eka tinhlohlorhi to koma (timinete), naswona ayi tshuki yiva ehenhla ka 327°C (ku bola). Milawu ya FDA na EU a yi boxi nkarhi wa misava hinkwayo – nkarhi wa ku hlangana loku hlayisekeke wu titshege hi mahiselo naswona wu fanele ku tiyisisiwa hi swikambelo swa ku rhurha leswi tekelelaka swiyimo swa xiviri.

Thepi ya mahiselo yale henhla ya PTFE yi lava vuhlayiselo lebyi faneleke ku hlayisa ku namarhela ka yona, ku olova, na matirhelo ya ku humesa. Swilaveko swa nkoka swikatsa vulawuri bya mahiselo (10-30°C), kutsakama ehansi ka 60%, ku papalata ku vonakala, ku hambanisiwa ka ti khemikhali, ku vekiwa ka vertical, na ku nghenisiwa ka moya. Landzelela vulawuri bya nhundzu ya FIFO naswona u kambela nkarhi na nkarhi.

Ku hlawula thepi ya kahle ya PTFE ya mahiselo yale henhla eka mubedo wo hisa wa 3D printer swilava ku kongomisa eka swikombiso swa mune swa nkoka: ku tiya ka mahiselo (kufika eka 260°C+), substrate leyi tiyisisiweke hi fiberglass (0.18mm ideal), silicone adhesive backing leyingana non-stick top surface, na ku anama/ku tiyisela loku faneleke. Nkongomiso lowu wu ku pfuna ku papalata ku soholota, masalela ni ku tsandzeka ka ku gandlisa.

Mahiselo ya glass transition (Tg) ya silicone pressure-sensitive adhesive ya kwalomu ka -120°C – yale hansi swinene kutlula ti acrylic adhesives. Tg leyi yale hansi swinene yi hlayisa PTFE high-temperature tape yi olova naswona yi namarhela hambi kuri eka -70°C, leswi sivelaka ku pandzeka ka brittle xikan’we naku endla leswaku kuva na ku namarhela loku tshembekaka eka switirhisiwa swa cryogenic.

Thepi ya mahiselo yale henhla ya PTFE yinga pandzeka kumbe ku tshoveka ehansi ka swiyimo swo phindha-phindha swo gombonyoka na ku pfula. Xihloko lexi xi hlamusela ndlela yo sivela leswi hiku hlawula kahle substrate (glass fibre reinforced), ku enta lokunene (0.18mm tani hi standard), ku hlawula silicone adhesive, na tindlela letinene to veka.

Ku hlawuriwa ka phepha ro humesa kumbe substrate ya filimi na xitirhisiwa xo humesa swi khumba hi ku kongoma ku tshamiseka ka vuhlayiselo na matirhelo ya ku rhurhumela ka thepi ya mahiselo ya le henhla ya PTFE. Xihloko lexi xi pimanisa PET vs. kraft paper substrates na silicone vs. fluorinated release agents, leswi ringanyetaka nhlanganelo lowunene wa zero-residue peeling xikan’we naku tshembheka ka nkarhi woleha.

Tithepi ta PTFE ta mahiselo yale henhla ti tirhisiwa ngopfu eka ku pfalela gezi, kambe swiyimo swa frequency yale henhla na voltage yale henhla switisa makhombo yo hlawuleka: ku tshoveka ka gezi, ku humesiwa ka xiphemu, ku dyuhala ka mahiselo, ku lahlekeriwa hi signal ya frequency yale henhla, na ku twisisa mbango. Xihloko lexi xi hlamusela khombo rin’wana ni rin’wana ni ndlela yo ri papalata.

Xihloko lexi xi hlamusela ndlela yo sivela ku thyakisa na ku onhaka ka matirhelo eka tlhelo leri nga namarheliki ra thepi ya mahiselo ya le henhla ya PTFE hi nkarhi wa endlelo ro peta. Maendlelo ya nkoka ya katsa vulawuri bya xihlovo (ku tshungula ka le henhla loku kongomeke), ku hambanisiwa hi nyama (tifilimi to sirhelela, ti non-stick rollers, zoned drying), na
