Zvivakwa zvemuviri uye zvikumbiro zvePolyimide (PI) uye PolytetraFluorohylene

Hunhu hwepanyama uye chigadzirwa application yePolyimide (polyimide, akapfupikiswa sePi) zvigadzirwa:

1. Ultra-yakakwira tembiricha uye ultra-yakaderera tembiricha kuramba: iyo yekushisa tembiricha iri -272 ~ + + 360 ° C, uye tembiricha yakakwira inogona kusvika 500 ° C.00.

2. Pfeka kupokana: Iyo PV inokoshesa kukosha kwemamiriro asina-lubricated inopfuura kagumi idzo dzenyama yechiJenji, uye zvinogona kuramba zvakashata uye nekuvapfeka kusimba.

3. Kushambadzira uye kupokana kwekukanda: Hazvizopfekedza kupisa kwakanyanya uye kunogona kutsungirira mitoro yepamusoro. Iyo Creep Kukosha pa300 × uye 18.2mpa kwemaawa 1000 ingori chete 0.6%.

4. Rinorwisa Plasma uye akasiyana marangi.

5. Ultra-vacuum application: Iyo ine yakaisvonaka chisimbiso kuita, iyo inogona kusvika 10-10torr., Uye ine chekuita nemuchina wakanaka.

Inoshandiswa zvakanyanya mun ndege, mauto, mota, michina yehofisi, zviridzwa zvemagetsi, zvinoda kurwisa, kusimbisa, kusimbisa, kugadzikana kwekushomeka uye deformation. Chigadzirwa icho chinosanganisira kusimbisa mhete, kusundira kushambidza, kushambidza mabhairi, vacuum pombi, zvigaro zvevarovhu, gers, nezvimwe.

Zvigadzirwa zvePolyimide zvinogona kunge zvakakamurwa muPI yakachena zvinhu zvigadzirwa uye pi inosanganisira zvigadzirwa zvinhu:

1. PI Yakachena Zvinhu Zvigadzirwa

100% yakachena polyimide resin inogona kuumbwa, jekiseni rakaumbwa uye rakawoneka. Iyo ine yakanakisa yakazara zvinhu, yakanyanya manhamba emagetsi uye magetsi ekudzivirira uye anodziya ekudziya, kupfeka kupokana (pfekai basa (yakakwirira pv kukosha) uye yakanakisa saizi yakagadzikana. Zvigadzirwa zvechigadzirwa zvinonyanya kusanganisira nharaunda neakakwirira zvakaringana zvinodiwa zvechinongedzwa zvivakwa, kuchena, kupisa kwekusimbisa uye kuisimbisira, uye kupokana kwemhino. Chaizvoizvo zvinoshandiswa zvinosanganisira zvigaro zvevharanda, zvakaumba kupisa zvipenga, torch torch SWirl mhete, nguva yekugara gear tensiers, uye pepa rekudhinda. Kuparadzanisa Claw, Brake Pad Sensor Somponder, Etc.

2. Pi idzo zvigadzirwa

2-1 PI uye PTFE YAKAITWA MABHUKU

Iyo yakaumbwa ne15% polytetrafluoroethery ptfe uye polyimide pi resin yekuvandudza kuparara kwechigadzirwa uye kuita kuti saizi yakagadzikana. Chaizvoizvo zvinonyorwa zvinonyanya kusanganisira zvisimbiso zvepamusoro, zvindori zvekupisa, gwara rakapfeka zvindori, compressor piston mhete, kupisa-kurwisa magiya, et.

2-2 PI uye graphite composite zvigadzirwa

Yakaumbwa ne15% graphite uye polyimide pi resin, ine chakanakisa kupfeka kurwisa pasi pePamusoro PV kukosha kwePV. Zvigadzirwa zvechigadzirwa zvinonyanya kusanganisira dzakasiyana-siyana chisimbiso chivhete uye laling mhete, dzakasiyana siyana kutsvedza. Maitiro ekushandisa anosanganisira kukanda gatsiti, kusimbisa mhete, hydron lyralic lyling lights bushing, miniature dendaling byting

Yakaumbwa ne40% graphite uye polyimide pi resin, ine yakaderera kwazvo coefficient yekuwedzera mutsara uye yakaderera coefficient yekukakavara. Izvo zvakakodzera nzvimbo yekushandisa neyakafara yekushanda tembiricha uye zvakakwirira zvinodiwa pakugadzikana kwezvikamu, sezvo zvinyorwa zvekurira zvine mwera, sekurondedzera mhete dze hydraulic motors uye hydraulic boosters.

2-3 zvigadzirwa zvezvigadzirwa zvePi, graphite uye ptfe

Yakaumbwa ne15% graphite, 10% ptfe uye polyimide pi resin, ine yakanyanya kupfira kupokana kwekunyepedzera uye yakakodzera kune yakakwirira-yekumhanyisa mamiriro ekushanda.

Chigadzirwa chechigadzirwa chinonyanya kuve che piston inosimbisa mhete uye laling mhete. Nekuda kwekunaka kwayo kupfeka kuramba uye kugadzikana kwakasimba, kwakanyanyisa kuvimbika kune chisimbiso chegesi.

2-4 composite zvigadzirwa zvePi uye molybdenum kukuvara

Kuumbwa ne15% molybdenum kukuvara uye polyimide pi resin, ine yakanaka kupfeka kurwisa uye kuita chisimbiso mumamiriro ekunze eVaPuum. Iyo chigadzirwa shandisa nharaunda inosanganisira kushandiswa kweiyo ultra-vacuum uye ekunze nzvimbo nzvimbo, uye inogona kugadzirwa muhuwandu hwechigaro uye bayonet.

Zvigadzirwa zvePi uye Molybdenum Kupandukira kwakanyanyisa kushandiswa mumasangano emapendekete uye maindasitiri akadai semafuta emazwi, zvidyarwa zvemakemikari, zvidyarwa zvemagetsi uye zvimwe zvigadzirwa zvekubata. Iyi manyorero inoshandiswa semiromo yemuromo, pahuro bhuroka uye kutakura pombi, iyo inogona kudzora carbide yerudzi, zvakanyanya uye kuvimbika kwepombi uye kuvandudza pombi, uye kuvandudza kushanda kweiyo Pombi, iyo inogona kuderedza zvinobudirira mutengo wepombi. Iko kugona kwekuremera panguva yekushanda kunogona kuderedzwa neanopfuura makumi mashanu muzana.

2-5 Pi uye Diamond Resin Composite Zvigadzirwa:

Ultrafine polyimide pi resin inogona kushandiswa seyekurumidzira mumiririri wedhaimondi kugomera mavhiri uye anorema-basa resin anogeda. Hazvibudise zvakaderera zvinoshamisa panguva yekurapa, zvine hukama hwakanaka nevakadzi vakasiyana-siyana, simba repamusoro, uye kushanduka kwakasiyana. , anogona kutsungirira muedzo wekudyira hombe, kunyatsogadzira ndeye 35 ~ 50% yakakwirira kupfuura iyo yeiyo phenolic resing vhiri, uye hupenyu hwebasa hunowanda kupfuura kanopfuura kaviri. Nekuda kwekunaka kwayo kupfeka kupokana, kupisa kupokana, zvine mwero zvekunyungudika uye kugadzirisa, zvakakwirira uye zvakadzika zvidzitiro zvinopesana, zvinodziya zvemagetsi zvinokatyamadza uye zvidimbu zvekuzvimiririra uye zvikamu zvezvikamu.
