Ufuna ukwazi ukuthi yiziphi izinhlelo zokusebenza zefilimu ye-polyimide? Bheka lezi

Ifilimu ye-Polyimide ingenye yemikhiqizo yokuqala ye-polyimide, esetshenziselwa ukufakwa kwe-slot kwamamotho kanye nezinto zokugoqa izintambo. Imikhiqizo eyinhloko i-DuPont Kapton, uchungechunge lwe-Ube Industries’ Upilex kanye ne-Zhongyuan Apical.

Ifilimu ye-polyimide esobala ingasetshenziswa njengepuleti lesisekelo seseli yelanga eguquguqukayo. Oseyili be-IKAROS benziwe ngamafilimu e-polyimide nemicu. Imicu ye-Polyimide ingasetshenziswa ukuhlunga amagesi ashisayo, futhi imicu ye-polyimide ingahlukanisa uthuli namakhemikhali akhethekile esisi esikhipha umoya.

1. Upende: Isetshenziswa njengopende ovikelayo wentambo kazibuthe, noma njengopende ongamelana nezinga lokushisa eliphezulu.

2. Izinto ezihlanganisiwe ezithuthukisiwe: ezisetshenziswa endaweni yezindiza, izindiza kanye nezingxenye zamarokhethi. Ingenye yezinto zesakhiwo ezimelana nokushisa okuphezulu. Isibonelo, uhlelo lwezindiza ezithwala abantu eziphezulu zase-US ludizayine isivinini esingu-2.4M, izinga lokushisa elingaphezulu elingu-177°C phakathi nendiza, nempilo yesevisi edingekayo yamahora angu-60,000. Ngokwemibiko, u-50% wezinto zokwakha zinqunywe ukuthi zisekelwe ku-thermoplastic polyimide resin. Inani lezinto eziyinhlanganisela eziqiniswe nge-carbon fiber endizeni ngayinye lilinganiselwa ku-30t.

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

I-4, ipulasitiki yegwebu: isetshenziswa njengento yokushisa ephezulu yokushisa.

5. Amapulasitiki obunjiniyela: Kunezinhlobo ze-thermosetting kanye ne-thermoplastic. Izinhlobo ze-Thermoplastic zingabunjwa ngokucindezelwa noma zibunjwe ngomjovo noma zibunjwe. Ikakhulukazi isetshenziselwa ukuzigcoba, ukuvala uphawu, insulating kanye nezinto zokwakha. Izinto ze-Guangcheng polyimide seziqalile ukusetshenziswa ezingxenyeni zemishini ezifana nama-compressor rotor, amasongo e-piston kanye nezimpawu zephampu ezikhethekile.

6. Ulwelwesi oluhlukanisayo: Isetshenziselwa ukuhlukanisa amapheya egesi ahlukahlukene, njenge-hydrogen/nitrogen, nitrogen/oxygen, carbon dioxide/nitrogen noma i-methane, ukususa umswakama kugesi ephakelayo ye-hydrocarbon yomoya kanye notshwala. Ingasetshenziswa futhi njenge-pervaporation membrane kanye ne-ultrafiltration membrane. Ngenxa yokumelana nokushisa kwayo nokumelana nezinyibilikisi zemvelo, i-polyimide ibaluleke ngokukhethekile ekuhlukaniseni amagesi emvelo noketshezi.
