Thermal Insulation ye Spacecraft Zvikamu
Heat Shield Dziviriro
PTFE fiberglass tepi inoita basa rakakosha mukuchengetedza spacecraft nhovo dzekupisa. Iyo tepi yakasarudzika kupisa inopikisa uye yakaderera kupisa conductivity inoita kuti ive yakakodzera kuvharidzira zvinhu zvakakosha panguva yekupindazve kwemhepo. Nekushandisa matinji efiberglass tepi yakavharwa neTeflon PTFE pakupisa nhovo, mainjiniya anogona kugadzira chinovharira chinopisa chinoshingirira kutonhora kwakanyanya, kuve nechokwadi chekuchengetedzwa kwechitundumuseremusere nevanogara pachiri.
Cryogenic Fuel Tank Insulation
Munzvimbo ye cryogenic mafuta ekuchengetedza, PTFE fiberglass tepi inoratidza kukosha. Vagadziri vezvemuchadenga vanoshandisa tepi iyi kuvhara mvura yehydrogen neokisijeni matangi, vachichengetedza tembiricha yakadzikira zvakanyanya inodiwa kune aya mapropellant. Kugona kwetepi kuramba kuchichinjika uye kuchengetedza zvimiro zvayo zvinodzivirira patembiricha ye cryogenic inoita kuti ive sarudzo yakanakisa yekudzivirira kutamisa kupisa uye kuderedza kubikira kwemafuta mu spacecraft mafuta masisitimu.
Thermal Management muSatellite Systems
Satellite inoshanda munzvimbo yakaoma yenzvimbo, uko kushanduka kwekushisa kunogona kunyanyisa. PTFE fiberglass tepi inoshandiswa mukupisa manejimendi masisitimu kudzora tembiricha mukati mesetiraiti zvikamu. Yayo yakaderera outgassing zvimiro uye kuramba kuderedzwa kubva ku UV mwaranzi inoita kuti ive chinhu chakanakira chenguva refu nzvimbo yekushandisa, kuve nechokwadi chehupenyu hurefu uye kuvimbika kweakakosha satellite masisitimu.
Dziviriro Kuputira kune Sensitive Wiring Systems
Electromagnetic Interference Shielding
Electromagnetic interference (EMI) inyaya yakakomba muaerospace masisitimu, uko kunyangwe kukanganiswa kudiki kwechiratidzo kunogona kukanganisa mabasa akakosha. PTFE yakavharwa nefiberglass tepi inopa yakasimba EMI dziviriro kana ichinge yaiswa kune mawaya mawaya uye inonzwisisika tambo masumbu. Iyo tepi inoitisa uye dielectric zvimiro zvinogadzira chinodzivirira chinovharira ekunze magetsi emagetsi uku ichidzivirira mukati mechiratidzo kubuda. Izvi zvinova nechokwadi chekushanda kusingapindiki kwekutaurirana arrays, kudzora ndege masisitimu, uye navigation yemagetsi, kunyangwe munzvimbo dzepamusoro-frequency. Huremu hwayo huremu hunoita kuti ive yakakosha kune aerospace application, uko huremu huremu hwakakosha.
Abrasion uye Chafing Kudzivirira
Wiring masisitimu mundege uye spacecraft inoramba ichioneswa kuvhiyiwa, kushanduka, uye kufamba panguva yekushanda. Nokufamba kwenguva, aya mamiriro anogona kukonzera abrasion, kuparara kwe insulation, kana kutadza zvachose waya. Teflon yakavharwa nefiberglass tepi inoderedza njodzi iyi nekuita seyakasimba yekudzivirira yekuputira. Yayo yakatsetseka, isina-tsvimbo inoderedza kupokana uye kusangana nekushushikana, zvichibatsira kuchengetedza kutendeseka kwewaya insulation. Iyo tepi inonamatira yakachengeteka asi ichichinjika, ichichinjika kune yakasimba mabhendi uye yakaoma nzira nzira. Iyi yakawedzerwa dhizaini yekudzivirira inowedzera hupenyu hwesevhisi ye wiring system uye inoderedza kuwanda kwekugadzirisa kunodhura uye kuderera.
Kemikari Resistance muHash Environments
Nzvimbo dzemuchadenga dzinofumura zvinhu zvemagetsi kumvura ine hukasha semafuta endege, maoiri ehydraulic, uye zvinonyungudutsa zvemaindasitiri. PTFE fiberglass tepi, inozivikanwa nekunaka kwayo kemikari inertness, inoumba chipingamupinyi chinoshanda kana chakaputirwa newaya uye zvinobatanidza. Inopikisa kutorwa uye kushatisa, kunyangwe mushure mekuratidzwa kwenguva refu kune zvinoora. Kudzivirirwa uku kunobatsira kuchengetedza kurongeka uye kushanda kwekuvimbika kwemagetsi ekudzivirira uye conductive zvinhu. Nekuda kweizvozvo, masisitimu akaputirwa muPTFE tepi haanyanye kubatwa nekuora, mapfupi maseketi, kana kutadza kwemagetsi, nekudaro anotsigira kushanda kwakachengeteka uye kwenguva refu mumamiriro endege akaoma.
