Ukuhlaziywa Kafushane Kokusebenza Okungokoqobo kwe Ifilimu ye-Polyimide

Ifilimu ye-Polyimide ingenye yempahla yokuqala ye-polyimide, esetshenziselwa ukufakwa kwe-slot kwamamotho kanye nezinto zokugoqa izintambo. Imikhiqizo eyinhloko i-DuPont Kapton, uchungechunge lwe-Ube’s Upilex kanye ne-Zhongyuan Apical. Amafilimu e-polyimide asobala asebenza njengezingcweti zamaseli elanga aguquguqukayo. Iziseyili ze-IKAROS zenziwe ngamafilimu e-polyimide nemicu. Emkhakheni wokuphehla amandla ashisayo, imicu ye-polyimide ingasetshenziswa ukuhlunga amagesi ashisayo, futhi imicu ye-polyimide ingahlukanisa uthuli nezinto ezikhethekile zeKhemikhali.

I-Coating: Njengopende ovikelayo wentambo kazibuthe, noma njengopende ongamelana nezinga lokushisa eliphezulu.

Izinto ezihlanganisiwe ezithuthukisiwe: ezisetshenziswa ku-aerospace, indiza kanye nezingxenye zamarokhethi. Ingenye yezinto zesakhiwo ezimelana nokushisa okuphezulu kakhulu. Isibonelo, indiza yabagibeli enamandla kakhulu e-United States iklanyelwe ukuthi ibe nesivinini esingu-2.4M, izinga lokushisa elingaphezulu elingu-177°C phakathi nendiza, nempilo yesevisi edingekayo engu-60,000h. Kubikwa ukuthi u-50% wezinto zokwakha zinqunywe ukuthi ziyi-thermoplastic polyimide njenge-resin ye-matrix. we-carbon fibre eyinhlanganisela yezinto eziqinisiwe, inani lendiza ngayinye lilinganiselwa ku-30t.

I-Fiber: I-modulus ye-elasticity ingeyesibili kuphela ku-carbon fiber, esetshenziswa njengesihlungi semidiya yokushisa ephezulu kanye nezinto ezikhipha imisebe, kanye nezindwangu ezingangenwa izinhlamvu nezingashi. Imikhiqizo eyahlukene ye-polyimide ikhiqizwa e-Changchun, e-China.

Ipulasitiki ye-Foam: isetshenziswa njengento yokushisa ephezulu yokushisa.

Amapulasitiki obunjiniyela: Kukhona ama-thermosets nama-thermoplastics. I-Thermoplastics ingabunjwa ngokucindezelwa noma ibunjwe ngomjovo noma idluliselwe. Ikakhulukazi isetshenziselwa ukuzigcoba, ukuvala uphawu, insulating kanye nezinto zokwakha. I-Guangcheng polyimide materials isetshenziswe ezingxenyeni zemishini ezifana ne-compressor rotary vanes, amasongo e-piston kanye nezimpawu zephampu ezikhethekile.

I-membrane yokuhlukanisa: isetshenziselwa ukuhlukanisa amapheya egesi ahlukahlukene, njenge-hydrogen/nitrogen, i-nitrogen/oxygen, i-carbon dioxide/nitrogen noma i-methane, njll., ukususa umswakama emoyeni we-hydrocarbon feed gas notshwala. Ingasetshenziswa futhi njenge-pervaporation membrane kanye ne-ultrafiltration membrane. Ngenxa yokumelana nokushisa kanye nokumelana ne-organic solvent ye-polyimide, ibaluleke kakhulu ekuhlukaniseni amagesi aphilayo noketshezi.
