Polyimide: Chirungu zita renhoroondo (PI yepfupi)
Polyimide seyakakosha engineering zvinhu, yanga ichishandiswa zvakanyanya mukupiwa, Aerospace, ma microyelectronics, nano, mvura yekristrane, laser uye imwe minda. Nguva pfupi yadarika, nyika dzirikutsvaga, dzichikudziridza uye kushandisa polyimide seimwe yemapurasitiki ekuvimbisa muzana. Polyimide, nekuda kwezvinhu zvacho zvakaringana mukuita uye synthesis, ingave ichirongwa zvinhu zvakazara, inozivikanwa se "Dambudziko Solver" (uye kuti "hapana Polyimide haazove neanhasi micreilelectronicsions tekinoroji.
Polyimide is a molecular chimiro chine makesi-based cake ) mapoka mana.
Polyimide pi parizvino mhando dzakanakisa dzeinjiniya mapurasitiki ekupisa, dzimwe mhando dzinogona kutsungirira tembiriro remangwanani , murazvo unodzoreredza, kudzikisira zvemagetsi, kuumbwa kwakaoma, kuumbwa kwezvidiki, mafuta, usadzivisa alkali solkali, isa hupamhi hwakanaka, kuita kwebrasion
Zvigadzirwa zvePolyimide zvemagetsi nemagetsi, indasitiri yemagetsi yekudhinda yakadhindwa mapuranga, zvishandiso zvekusimbisa, idzi tambo dzinodzivirira, zvigadziko, zvigadziko nemimwe minda.
HONY PLUPLATION SOMORTITIONS mukugadzirwa uye kugadziriswa kwetsika dzePolyimizents, gasi, uye kuumbwa jekiseni kuumbwa kwezvinhu zvakasiyana-siyana zvePolyimide zvigadzirwa.
Kuita kwezvigadzirwa zvePolyimide

8, Polyimide ndeyekuzvidzivirira-yekuzvidzima polymer, stopto stow rate.
9, Polyimide mune yakanyanya kuderera pasi pekupenya kushoma.
10, polyimide haina chepfu, inogona kushandiswa kugadzira tafura uye * midziyo, uye yakadzika k000 yenguva. Pane imwe polyimide ine zvakare yakanaka kwazvo biocomputer, muyedzo yekuenzanisa kweropa kune isiri-hemolytic, mu vitro cytototoxity bvunzo yezvisiri-zvine chepfu.
Kushandiswa kwezvigadzirwa zvePolyimide
Semhedzisiro yeiyo polyimide iri pamusoro mukuita uye muyunivhesiti, mune dzimba zhinji phermers, zvakaoma kuwana senge phepita ine huwandu hwenzvimbo dzekushandisa, uye mune imwe yezvinhu izvi zvakaratidza kushanda kwakasimba.
1, Firimu: Polyimide * imwe yezvinhu zvekutanga, inoshandiswa kune mota slot insulting uye tambo yemhepo yemhepo. Zvigadzirwa zvekutanga zviri Dupont Kapton, Ube's Upilex Series, uye Jongbuchi Apical. Rwakapepuka polyimide firimu rinogona kushandiswa seyakajaira solar cell backing plate.
2..
3. Iyo ndeimwe yeiyo * yakakwira tembiricha inorwisa zvinhu zvekugadzira zvinhu. Semuenzaniso, United States yeAlperonic Airliner chirongwa chakagadzirirwa kukurumidza kwe294m yezvinyorwa zveiyo thermoplastic polimide seye matrix resin carbon fiber yakasimbiswa midziyo yemidziyo, huwandu hwenyepi imwe neimwe ndege dzinenge 30t.

12. Magetsi - Optical Zvishandiso: Inoshandiswa seyangoita kana inoshanda waveguide midziyo yekuchinja, etc., polyimide
Mukupfupikisa, hazvina kuoma kuona chikonzero nei polyimide inogona kubuda kubva kuma60s, mazhinji ezvinyorwa zvehutachiona
Basa rePolyimide gasi mune zvakadzama
Polyimide gasket inzvimbo yepamusoro-plast castimki gasket yakagadzirwa nePolyimide zvinyorwa. Iyi gasket inoita basa rakakosha mukugadzirwa kwemaindasitiri, kunyanya kuratidzwa mune zvinotevera zvinhu:
Kutanga, basa rekuisa chisimbiso
Polyimide gasi rinowanzoshandiswa semidziyo yekubatanidza nekuda kwekushanda kwavo kwakanaka uye kurwisa kwehutori. Mumupundu, mavhavha, mapapu uye mamwe mashandiro ezvekushandisa, kushandiswa kwePolyimide magesi kunogona kudzivirira gasi kana kuti mvura quakage, kuve nechokwadi chekushanda kwakajairika kwehurongwa.
Chechipiri, basa rekusimbisa
Nekuda kweiyo yakanaka kwazvo yemagetsi insulation yezvivakwa zvePolyimi, saka polyimide gatsika dzinowanzoshandiswa semasitsi ekusimbisa kwemidziyo yemagetsi. Zvinogona kuita zvinobudirira dunhu, dzivirira kuremara kwazvino kana dunhu pfupi, nekudaro inovandudza kuchengetedzeka uye kugadzikana kwemidziyo yemagetsi.
Chetatu, buffer mhedzisiro
Mumidziyo yemuchina, zvikamu zvakawanda mukushanda zvichaburitsa vibration uye kukanganisa. Polyimide Gasket Pamusoro peKupfeka Kwakanaka uye kupfeka kurwisa, kunogona kutamba buffer pakati pezvidimbu izvi, kuderedza kupfeka uye ruzha, wedzera hupenyu hwebasa hwemidziyo.
Chechina, Kemical Corrosion Rishance
Zvigadzirwa zvePolyride zvine zvakanakisa zvemakemikari kupesana, kunogona kuramba dzakasiyana-siyana acids, alkalis, organic solses uye zvimwe zvinhu zvemakemikari. Naizvozvo, mumakemikari uye maindasitiri emakemikari, polyimide gatsiti rinoshandiswa zvakanyanya mumapipi akasiyana-siyana, anogadzira uye zvimwe zvinoshandiswa nemidziyo.
Mukupfupikisa, polyimide gasi matema anotamba akawanda makiyi mabasa mukugadzirwa kwemaindasitiri. Kupesana kwakanyanya kukuru, kupokana, kupfeka kurwisa uye kugona kwakanakisa uye kugona kwemagetsi zvinhu, zvichiita chikamu chakakosha mumachina akasiyana siyana nemidziyo. Kunyangwe muchisimbiso, insolis, cushioning kana kupokana kwemakemikari, polyimide gatsika dzakaratidza kuita kwakanaka.
