Chechina, kushandiswa kwepolyimide:
Nekuda kwehunhu hwepolyimide yadudzwa pamusoro mukuita uye makemikari ekugadzira, zvakaoma kuwana zvakasiyana-siyana zvekushandisa se polyimide pakati pemapolymer mazhinji, uye inoratidza kushanda kwakanyanya mumativi ese..
1. Firimu: Ndechimwe chezvigadzirwa zvekutanga zvepolyimide, iyo inoshandiswa pakuisa slots yemotor uye nekuputira zvinhu zvetambo.Zvigadzirwa zvikuru iDuPont Kapton, Ube Industries 'Upilex akatevedzana uye Zhongyuan Apical.Transparent polyimide mafirimu anoshanda seanochinjika solar cell substrates.
2. Coating: inoshandiswa se insulating varnish ye electromagnetic wire, kana kushandiswa seyepamusoro tembiricha inodzivirira coating.
3. Yepamberi composite zvinhu: anoshandiswa mune aerospace, ndege uye rocket zvikamu.Ndiyo imwe yeakanyanya kupisa tembiricha inopikisa structural materials.Semuenzaniso, US supersonic airliner program yakagadzirwa nekumhanya kwe2.4M, tembiricha yepamusoro ye177 ° C panguva yekubhururuka, uye hupenyu hwebasa hunodiwa hwe60,000h.Sekureva kwemishumo, 50% yezvigadzirwa zvakatemerwa kushandisa thermoplastic polyimide sematrix resin.Carbon faibha yakasimbisa zvinhu zvinoumbwa, huwandu hwendege imwe neimwe hunosvika makumi matatu.
4. Fiber: Iyo modulus ye elasticity ndeyechipiri kune kabhoni fiber.Inoshandiswa sesefa zvinhu zvepamusoro-tembiricha midhiya uye radioactive zvinhu, pamwe nebulletproof uye machira asingapindi moto.
5. Purasitiki yefoam: inoshandiswa seyakanyanya tembiricha isingadziviriri kupisa zvinhu.
6. Injiniya mapurasitiki: Kune thermosetting uye thermoplastic marudzi.Thermoplastic mhando dzinogona kuumbwa kana jekiseni kuumbwa kana kutamisa kuumbwa.Inonyanya kushandiswa kuzvi- lubrication, kuisa chisimbiso, insulation uye zvimiro zvezvinhu.Guangcheng polyimide zvinhu zvatanga kuiswa kune mechaniki zvikamu se compressor rotary vanes, piston mhete uye yakakosha pombi zvisimbiso.
7. Adhesive: inoshandiswa seyakanyanya tembiricha yemaitiro adhesive.Guangcheng polyimide adhesive yakagadzirwa seyakakwira-insulation potting komboni yezvigadzirwa zvemagetsi.
8. Kuparadzanisa membrane: inoshandiswa pakuparadzaniswa kwemarudzi akasiyana-siyana egasi, akadai sehydrogen / nitrogen, nitrogen / oxygen, carbon dioxide / nitrogen kana methane, nezvimwewo, kubvisa unyoro kubva kumhepo hydrocarbon feed gas uye doro.Inogona zvakare kushandiswa senge pervaporation membrane uye ultrafiltration membrane.Nekuda kwekupikiswa kwekupisa uye organic solvent kuramba kwepolyimide, yakakosha kukosha mukuparadzaniswa kwemagasi egasi uye zvinwiwa.
9. Photoresist: Pane zvakaipa uye zvakanaka zvinopikisa, uye kugadzirisa kunogona kusvika submicron level.Inogona kushandiswa mufirimu yemuvara musanganiswa nepigment kana dhayi, izvo zvinogona kurerutsa maitiro ekugadzirisa.
10. Kushandisa muzvigadzirwa zve-microelectronic: se dielectric layer ye interlayer insulation, se-buffer layer yekuderedza kushungurudzika uye kuvandudza goho.Sechidziviriro chekudzivirira, chinogona kuderedza kupesvedzera kwezvakatipoteredza pamudziyo, uye inogonawo kudzivirira ma-particles, kuderedza kana kubvisa kukanganisa kwakapfava (kupfava) kwechigadzirwa.
11. Alignment agent ye liquid crystal display:Polyimideinobata basa rakakosha mukurongeka kwezvinhu zveTN-LCD, SHN-LCD, TFT-CD uye remangwana ferroelectric liquid crystal display.
12. Electro-optic materials: inoshandiswa se passive or active waveguide materials, optical switch materials, etc. Fluorine-containing polyimide inopenya muhutano hwekutaurirana wavelength, uye kushandisa polyimide sechromophore matrix inogona kuvandudza kushanda kwezvinhu.kugadzikana.
Kupfupisa, hazvina kuoma kuona kuti sei polyimide ichigona kumira kunze kubva kune akawanda anonhuwirira mapolima eheterocyclic akaonekwa muma1960 nema1970s, uye pakupedzisira ikava kirasi yakakosha yezvigadzirwa zvepolymer.
5. Outlook:
Sechinhu chinovimbisa chepolymer,polyimideyave ichinyatso zivikanwa, uye kushandiswa kwayo mu insulating zvinhu uye zvimiro zvemukati zviri kuramba zvichiwedzera.Mukutaura kwezvinhu zvinoshanda, iri kubuda, uye kukwanisa kwayo kuchiri kuongororwa.Zvisinei, mushure memakore makumi mana ekuvandudzwa, haisati yava yakasiyana-siyana yakakura.Chikonzero chikuru ndechekuti mutengo uchiri wakanyanya kukwira kana uchienzaniswa nemamwe mapolymer.Naizvozvo, imwe yenzira huru yekutsvagisa polyimide mune ramangwana inofanira kuramba iri yekutsvaga nzira dzekudzikisa mutengo mumonomer synthesis uye polymerization nzira.
1. Synthesis yemamonomers: Mamonomers e polyimide dianhydride (tetraacid) uye diamine.Iyo synthesis nzira yediamine yakakura, uye madhayamu mazhinji anowanikwawo mune zvekutengesa.Dianhydride imonomer yakasarudzika, iyo inonyanya kushandiswa mukugadzirwa kwepolyimide kunze kweanorapa epoxy resin.Pyromellitic dianhydride uye trimellitic anhydride inogona kuwanikwa nechikamu chimwe-gasi chikamu uye fluid chikamu oxidation yedurene uye trimethylene yakatorwa kubva kune inorema inonhuhwirira oiri, chigadzirwa chepetroleum kunatsa.Mamwe madianhydrides anokosha, akadai sebenzophenone dianhydride, biphenyl dianhydride, diphenyl ether dianhydride, hexafluorodianhydride, nezvimwewo, akagadzirwa nenzira dzakasiyana-siyana, asi mutengo unodhura zvikuru.zviuru gumi zveyuan.Yakagadzirwa neChangchun Institute of Applied Chemistry, Chinese Academy of Sciences, yakakwirira-kuchena 4-chlorophthalic anhydride uye 3-chlorophthalic anhydride inogona kuwanikwa kubva o-xylene chlorination, oxidation uye isomerization kupatsanurwa.Kushandisa aya macommunisheni maviri sezvigadzirwa zvinogona kugadzira Series dianhydrides, ine mukana mukuru wekudzikisa mutengo, inzira yakakosha yekugadzira.
2. Polymerization process: Iyo ikozvino inoshandiswa nzira mbiri-nhanho uye imwe-nhanho polycondensation maitiro ese anoshandisa yakakwirira-inofashaidza zvinonyungudutsa.Mutengo weaprotic polar solvents wakanyanya kukwirira, uye zvakaoma kuvabvisa.Pakupedzisira, kurapwa kwepamusoro-soro kunodiwa.Iyo PMR nzira inoshandisa isingadhure doro solvent.Thermoplastic polyimide inogona zvakare kuve polymerized uye granulated zvakananga mu extruder ine dianhydride uye diamine, hapana solvent inodiwa, uye kushanda kwayo kunogona kuvandudzwa zvakanyanya.Ndiyo yakanyanya hupfumi synthesis nzira yekuwana polyimide nekunyatso polymerizing chlorophthalic anhydride ine diamine, bisphenol, sodium sulfide kana elemental sulfur pasina kuenda kuburikidza nedianhydride.
3. Kugadziriswa: Kushandiswa kwe polyimide kwakakura kwazvo, uye kune zvakasiyana-siyana zvinodiwa pakugadzirisa, zvakadai sekukwirirana kwepamusoro kwekugadzirwa kwefirimu, kutenderera, vapor deposition, sub-micron photolithography, yakadzika yakatwasuka madziro engraving Etching, hombe-nzvimbo, hombe- kuumbwa kwevhoriyamu, kuisirwa ion, laser precision process, nano-scale hybrid tekinoroji, nezvimwewo zvakavhura nyika yakafara yekushandiswa kwepolyimide.
Nekumwe kuvandudzwa kwehunyanzvi hwekugadzira tekinoroji yekugadzira tekinoroji uye kudzikiswa kwakanyanya kwemutengo, pamwe neayo epamusoro mekiniki zvivakwa uye magetsi ekudzivirira zvivakwa, thermoplastic polyimide zvirokwazvo ichaita basa rakakosha mumunda wezvigadzirwa mune ramangwana.Uye thermoplastic polyimide ine tarisiro zvakanyanya nekuda kwekuita kwayo kwakanaka.
6. Mhedziso:
Zvinhu zvinoverengeka zvakakosha zvekunonoka kukura kwepolyimide:
1. Kugadzirira kwezvinhu zvakasvibirira zvekugadzira polyimide: kuchena kwepyromellitic dianhydride hakuna kukwana.
2. Iyo yakasvibiswa yepyromellitic dianhydride, kureva, kubuda kwe durene kunogumira.Kubuda kwepasi rose: 60,000 matani / gore, kuburitsa mudzimba: 5,000 matani / gore.
3. Mari yekugadzira yepyromellitic dianhydride yakanyanya.Munyika, anenge 1.2-1.4 matani e durene anogadzira 1 toni ye pyromellitic dianhydride, nepo vagadziri vakanakisa munyika yangu parizvino vanogadzira anenge 2.0-2.25 matani e durene.matani, chete Changshu Federal Chemical Co., Ltd. yakasvika 1.6 matani/tani.
4. Chiyero chekugadzirwa kwepolyimide idiki kwazvo kuti igadzire indasitiri, uye maitiro epadivi epolyimide akawanda uye akaomarara.
5. Mazhinji mabhizinesi epamba ane chinyakare chinodiwa kuziva, izvo zvinoganhurira nzvimbo yekunyorera kune imwe nhanho.Vanowanzo shandisa zvigadzirwa zvekunze kutanga kana kuona zvigadzirwa zvekunze vasati vazvitsvaga kuChina.Izvo zvinodikanwa zvebhizinesi rega rega zvinouya kubva kune zvinodiwa nevatengi vepasi peiyo bhizinesi, mhinduro yeruzivo uye ruzivo;masource channels haana kutsvedzerera, kune akawanda epakati zvinongedzo, uye huwandu hweruzivo rwakakwana huri kunze kwechimiro.
