Phawula
Ityhutywe kwaye imbonakalo ebonakalayo, isihlobo se-1.39 ~ 1.45, ifilimu ye-polylimide inexesha elide, ukunganyangeki kombane, kunokusetyenziswa ixesha elide kuluhlu lobushushu lwe -269 ℃ ~ 280 ℃, ixesha elincinci linokufikelela kuma-400 ℃ ubushushu obuphakamileyo. Iqondo lokushisa leglasi ye-280 ℃ (i-prilex r), 385 ℃ (kapton) nangaphezulu kwe-500 ℃ (i-prilex s). 20 ℃ Amandla amanye amazwe angama-200 MPA, 200 ℃ angaphezulu kwe-100 MPA. Ngokukodwa ilungele ukusetyenziswa ngokutshaba kweebhodi zesekethe eziguqulelweyo eziprintiweyo kunye neentlobo ngeenyawo zemoto eziphezulu zemoto kunye nezixhobo zombane.
Ukwahlulahlula
I-polyoims ihlala icwangciswe kwiindidi ezimbini eziphambili.
I-Thermoplastic Polymidide, ezinjengeefilimu zokulinganisa, iimoto, iintsinga kunye nee-oopidernics zanamhlanje.
I-Tolymoset Polymoimide, ikakhulu kubandakanya i-bismaleimide (BMI) kunye ne-Monomer Polymerization (PMR) uhlobo lwepolimide kunye neemveliso zabo eziguqulweyo.
Ukuhlelwa kwefilimu
Kubandakanya i-bedne-uhlobo lwefilimu yefilimu kunye ne-biphenyl polymimide ifilimu ezimbini. Imveliso yangaphambili ye-Dead States, igama lorhwebo lukaKapton, nge-Benzene Tetracyboxyby Acid Dinhydride yenkqubo yeDamine. Le yokugqibela iveliswa yi-Japan Ibe iqumrhu, igama lokurhweba nge-bimilex, nge-bipheny yebhokisi ye-bipheny i-acid diamine kunye ne-diphiheny i-damine
Izibonelelo zoPolimide
(1) Ukumelana nobushushu obuhle. Iqondo lobushushu le-Polymimide lingaphezulu kwe-500 ℃, ngamanye amaxesha liphezulu, liyaziwa ukuba lolona lolunye uzinzo lwe-thelymeric, ikakhulu kuba i-molecular iqulethe inani elikhulu le-molematic.
(2) Iimpawu ezibalaseleyo zoomatshini. Amandla e-thansile ye-Matrix enganyanisekanga ingaphezulu kwe-100MPA. Ifilimu yeKapton ilungiselelwe iyunifomu ye-thehydride ye-anhydride ye-170MPA, kunye ne-biphenyl polylimide (i-bilex s) inokufikelela kwi-400MPA. I-Polylimide i-fiber i-fiber imocastity ingafikelela kwi-500MPA, yesibini kuphela kwi-carbon fiber.
(3) Uzinzo lweekhemikhali kunye nokuxhathisa ubushushu kunye nokufuma. Izinto zePolymide zihlala zingabhambulukanga kwizinyibilikisi zendalo, ukumelana nokuziphatha, ukunganyangeki kwe-hydrolysis. Guqula uyilo lwe-molecular lunokufumaneka kwiindidi ezahlukeneyo zesakhiwo. Ezinye iintlobo ezahlukeneyo ziyahambelana nengcinezelo ye-2, i-120 ℃, 500h yokubila.
(4) Ukunganyangeki kwe-radiation elungileyo. Ifilimu ye-Polymide kwi-5 × 109rad imitha, amandla asagcina i-86%; Abanye babeka i-fiber yefayibha nge-1 × 1010rad ekhawulezayo ekhawulezileyo eNytroni, inqanaba lokugcina amandla ama-90%.
(5) Iipropathi ezilungileyo zeDiectoric. I-Diectoric rhoqo ingaphantsi kwe-3.5, ukuba intshayelelo yeeathom ze-fluorine kwi-molecular thein, i-dielectric rhoqo incitshiswa i-10 ukuya kwi-300KV / mm, i-cm. Ke ngoko, i-synthesis ye-fluorine-enezixhobo ze-pollilodide yeyona ndawo idumileyo yophando.
Ezi ndawo zingasentla ziyazinza ngaphezulu koluhlu lwamaqondo obushushu ngokubanzi kunye nodidi lokuqhubeka. Ukongeza, i-polyomide inezikhundla zokuchasana nobushushu obuphantsi, ukulingana okuphantsi kolwandiso, ilangatye liyithole kwaye liyithole i-biomatise elungileyo. Ukusebenza kwe-Polymimide ye-Polymimide ye-Polymimide ye-Polymimide ye-Polymimide ye-Polylimide kunye nokungaguqukiyo kwi-chemistry ye-synthetic ivumela ukuba isetyenziswe kwizicelo ezahlukeneyo.
Izicelo
Yaziwa ngokuba yi "filimu yegolide" yefilimu yepolimide isebenza kakuhle, isetyenziswa ngokubanzi kwitekhnoloji yendawo, i-H, I-H-CIDS FILDE), i-PTC eprintiweyo (i-PTC (i-PTC I-TaPURTARTRARTARTE), i-aerospace, inqwelo moya, iikhompyuter, iimoto, izinto ze-elektroniki, ishishini le-elektroniki kunye namanye amashishini e-elektroniki kunye nombane.
Isibonelelo seSicelo
. Iimveliso eziphambili ze-dupton ye-dupton, i-pilex ye-pulisex ye-Under ye-UBE kunye ne-apical ye-zhong yuan. Ifilimu ebonakalayo ye-Polylimide inokusetyenziswa njengeseli eguquguqukayo ye-solar yelanga.

(5) UJuam: unokusetyenziswa njengezixhobo zokuhlawula ubushushu.
. Ukongeza, i-polyoimide nayo inokusetyenziswa njengendawo ephezulu yobushushu befilimu, ifilimu yokwahlula, ifoto, i-buffer ye-buffer, iarhente yekristali yekristali, izixhobo zombane, njl.
Ubume bangoku
Njengesixhobo esikhethekileyo sobunjineli, i-polyomide isetyenziswe ngokubanzi kwinqwelo moya, i-aerospace, yombane / i-elektroniki, i-ear, ifilimu engamanzi, i-leser, oomatshini bokubonisa, oomatshini bokuchasana nolawulo lweofisi ezenzekelayo. Kutshanje, amazwe aphanda, aphuhlisa kwaye asebenzise i-polyimidide yenye yezona zinto zithembisa iiplasitiki zobunjineli kwinkulungwane yama-21. I-Polymimide, ngenxa yeempawu zayo ezibalaseleyo ekusebenzeni nasekusebenzeni, nokuba zizinto ezenziwayo okanye njengezinto ezisebenzayo, amathemba ayo amaninzi abonakalisiwe, kwaye "akukho I-Polymidide ayiyi kuba neetekhnoloji ze-teedelectronis ". Kwinani elikhulu lezixhobo zePolymer, zithandathu kuphela kwi-United States Abststys (ca) sisihloko esahlukileyo, i-polyomidide yenye yazo. I-Polymimide yenye yazo. Oku kubonisa ukuba i-polyomide ibaluleke kakhulu kubuchwepheshe kunye neshishini. Ishishini le-IT, ishishini lepaneli yephaneli, ishishini lefotovoltaic kunye nolunye uphuhliso nolwenziweyo, ziya kukhokelela kuphuhliso lwezixhobo ezixhasayo ezixhasayo kunye nokukhula kwemfuno yentengiso. Ubunjineli be-elektroniki (iBakala le-elektroniki) ifilimu eprintiweyo iprintiweyo, iisekethe ezihlanganisiweyo, iiseli ze-flat, iilensi ze-elektroniki kunye nezinye izinto ezibalulekileyo, ezinye nangaphezulu zidlala indima ebaluleke kakhulu.
Ithemba le-polyomide
I-Polymimide njengezixhobo ezithembisayo ziqatshelwe, kwizinto zokuthambisa kunye nezinto zolwakhiwo kwisicelo ziyanda. I-Polymimide ivela njengento esebenzayo, kwaye amandla ayo asaphononongwa. Nangona kunjalo, emva kweminyaka engama-40 yophuhliso, ayikabi ziindidi ezikhulu, esona sizathu siphambili kukuba, xa kuthelekiswa nezinye iipolymers, iindleko ziphezulu kakhulu. Ke ngoko, enye yezona ndlela eziphambili zophando lwePolylimide kufuneka lube kwimeko ye-monomer synthesis kunye neendlela zepolymeri yokufumana iindlela zokunciphisa iindleko.
I-PILM Fill Ipho- kuphi
Ifilimu ye-PI ngokungqinelana nokusetyenziswa kwe-jikelele kunye nokungaxhathisi ubushushu ngenjongo yebakala lombane kunye nenqanaba le-elektroniki ngeemfuno ezifana nokuguquguquka kwamanani amabini. Ifilimu ye-PI ye-PI ngenxa yeemfuno ezisezantsi zekhaya ziye zakwazi ukuveliswa kobuninzi kunye nokusebenza kunye neemveliso zangaphandle azinawo umahluko omkhulu; Ifilimu ye-PI ye-PI ye-elektroniki ikwaphuhliswa kwe-FCCL kunye nokuvela kweendawo ezinkulu zefilimu ye-PI, ukongeza ekugcineni iipropathi zombane kunye noomatshini befilimu ye-PIRY PAR, Ubuso be-Anisotropy (ubukhulu bokuthetha) beka phambili iimfuno ezingqongqo ngakumbi. Ikamva lisafuneka lingenise inani elikhulu lefilimu yebanga le-elektroniki ye-elektroniki, isizathu kukuba ifilimu ye-PI yasekhaya ekwenzeni ifilimu ye-PI engeniswe i-PI apho kukho i-GIFAP ethile, ayinakukwazi ukuhlangabezana neemveliso zokuphela kwe-FCCL. Kwindawo eqingqiweyo yentengiso yexesha elizayo, ixesha elide amaxabiso efilimu yebanga le-elekle ye-elektroniki ilawulwa nguDupont, kodwa kwiminyaka yakutshanje, kunye ne-Korea ye-Korea ye-Korea ukuya kwimpembelelo Kwingxaki yezoqoqosho kwi-elektroniki yeemveliso ze-elektroniki, ixabiso lemveliso linciphile, kodwa ifilimu yebanga le-PI ye-ERCE ikwizixhobo zenzuzo ephezulu.
