Ukukhetha itheyiphu elungile ye-PTFE yokushisa okuphezulu kombhede oshisayo wephrinta ye-3D kudinga ukugxila ezinkomba ezine ezibalulekile: ukumelana nezinga lokushisa (kufika ku-260°C+), i-fiberglass-reinforced substrate (0.18mm ekahle), i-silicone enamathelayo esekelayo enendawo enganamathelanga phezulu, nobubanzi/ukubekezela okufanele. Lo mhlahlandlela ukusiza ukuthi ugweme ukungqubuzana, izinsalela, nokuhluleka kokuphrinta.

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.

Itheyiphu ye-PTFE yokushisa ephezulu ingaqhekeka noma iphuke ngaphansi kwezimo zokugoba nokuvula okuphindaphindiwe. Lesi sihloko sichaza ukuthi ungakuvimbela kanjani lokhu ngokukhetha okufanele kwe-substrate (i-fiber yengilazi iqiniswe), ukujiya okuphezulu (0.18mm njengokujwayelekile), ukukhetha kwe-adhesive ye-silicone, nezindlela zokufaka ezifanele.

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.

Amateyipu e-PTFE okushisa okuphezulu asetshenziswa kakhulu ekufakeni ugesi, kodwa izimo ze-high-frequency kanye ne-high-voltage zibeka izingozi eziyingqayizivele: ukuphuka kukagesi, ukukhipha ingxenye, ukuguga okushisayo, ukulahlekelwa kwesignali ye-high-frequency, kanye nokuzwela kwemvelo. Lesi sihloko sichaza ingozi ngayinye nendlela yokugwema.

I-Jiangsu Aokai New Materials Technology Co., Ltd. – umkhiqizi ochwepheshile wendwangu ye-Teflon eshisa kakhulu - inikeza lo mbono wobuchwepheshe: Lapho indwangu ye-Teflon enezinga eliphezulu lokushisa ithinta izinto ezincibilikisiwe ezincibilika, ukumanzisa phezulu nokunamathela akuvamile ukwenzeka. Lokhu kungenxa ye-polytetraf
