I-vespel luphawu lophawu loluhlu lwePlastiki ePhezulu lwePolyomide eyenziwe nguDupont.
Iimpawu kunye nezicelo
I-Vespel isetyenziswe ikakhulu kwi-aerospace, i-semicondcuctor, kunye netekhnoloji yokuThutha. Idibanisa ukumelana nobushushu, i-thambisa, uzinzo loqingqiweyo, ukunganyangeki kwamachiza, kunye nokunganyangeki kwechiza, kwaye kunokusetyenziswa kwiimeko ezinobutshaba kunye nokusingqongileyo.
Ngokungafaniyo neeplasitiki ezininzi, ayivelisi ngaphandle kwamaqondo angabalulekanga de kube ngamaqondo obushushu aphezulu, nto leyo eyenza iluncedo kwizihlangu zobushushu ezikhanyayo kunye nenkxaso entle. Ikwaqhuba kakuhle kwizicelo ze-vacuum, ezantsi kubushushu obuphantsi kakhulu amathambine. Nangona kunjalo, i-vepel ithanda ukufumana inani elincinci lamanzi, okukhokelela kwixesha elide lempompo ngelixa ibekwe kwi-vacuum.
Nangona kukho i-thollys idlula i-Polypimidide kwi-Prosteries nganye kwezi, ukudityaniswa kwayo yeyona nto iphambili ye-vespel.
Iipropathi ze-thermophysical
I-vespel isetyenziswa njengendawo yokulinganisa i-thermal yokuvavanywa kwezinto zovavanyo, ngenxa yokuzala kunye nokungqinelana kwezinto zayo ze-thermophysip. Umzekelo, inokumelana nokufudumeza okuphindaphindiweyo ukuya kuthi ga kwi-300 ° C ngaphandle kokutshintsha izinto zayo ze-thermal kunye noomatshini bokuyifumana] iitafile ezinkulu zobushushu, zonke izinto ezenziwa kubushushu, zipapashiwe.
Iipropathi zemagnetic
I-Vespel isetyenziswa kwizisombululo eziphezulu ze-NMR ye-NMR ye-numbertic of Covotic (-9.02 ± 0.8 ° C) isondele kakhulu kwi-De-1.0- Nge-6 ° C [6])) amaxabiso angalunganga abonisa ukuba zombini izinto ziDiamagnetic. Ukutshatisa amalungelo obuNcedisi weNkunyamba ye-Ignetic yezixhobo ezijikeleze isampulu ye-NMR kweyele yenyibiliki kunokunciphisa ukuthathwa kwemigca eyandisiweyo ye-magnetic yemigca ye-magnetic eyandisa imigca yokuphumla.
Ukuqhubekeka kwezicelo zokwenza imveliso
I-Vespel inokuqhubekiswa ngokuseka ngqo (i-DF) kunye ne-isostatic ye-isostatic (iimilo ezisisiseko-iipleyiti, iiron kunye neetyhubhu). Ngenani le-pretotype, iimilo ezisisiseko zihlala zisetyenziselwa ukusebenza kweendleko kuba isixhobo sibiza kakhulu kwi-DF. Imveliso enkulu ye-CCC enkulu, amalungu e-DF ahlala esetyenziselwa ukunciphisa iindleko zenxalenye, ekuchitheni iindleko zezinto ezibonakalayo eziphantsi kwezimilo ezisisiseko. [
Iintlobo
Kwizicelo ezahlukeneyo, iifomu ezikhethekileyo zidityanisiwe / zidityanisiwe. Iimilo ziveliswa ziinkqubo ezintathu eziqhelekileyo:
ukubumba ubunjineli (yeepleyiti kunye namakhonkco);
i-isostatic yokubumba (kwiintonga); kwaye
Ukwenza ngqo (iinxalenye ezincinci zesayizi eziveliswe kwimitha enkulu).
Iindawo ezenziwe ngqo zinempawu ezisezantsi zentsebenzo kunamalungu awo afunwayo ukusuka kwiimilo ezibunjiweyo okanye zesostatic. Iimilo ze-isostaticki zinepropathi yaseSotropic, ngelixa ngokuthe ngqo kunye ne-comps eved ye-faisppes i-anisotropic yomzimba.
Eminye imizekelo ye-polylimide eqhelekileyo yile:
I-SP-1 virn polymide
ibonelela ngamaqondo obushushu avela kwi-Crymogenic ukuya kwi-300 ° C (570 ° F), ukuxhaswa kweplasma ephezulu, kunye nenqanaba le-UL yombane omncinci kunye nokuqhutywa kombane. Esi sisiseko esingabhalwanga esingenasiphelo. Ikwabonelela ngamandla aphezulu omzimba kunye ne-maximal slongwetion, kunye neyona milinganiselo yombane kunye ne-inshurensi yokufaka i-inshurensi. Umzekelo: Vespel SP-1.
I-15% igrafu ngobunzima, i-SP-21
yongezwa kwi-resin yesiseko yokwanda kokunganyangeki kunye nokuncitshiswa kwezicelo ezifana nezicelo ezifana ne-eres, i-wales, iibhloko zetywina, iibhloko zesilayidi kunye nezinye izicelo zokunxiba. Le nqaku lelona candelo lilungileyo lamabakala azele ngamanqanaba apheleleyo, kodwa lingaphantsi kwebanga lentombi. Umzekelo: Vespel SP-21.
I-40% igrafu ngobunzima, i-SP-22
Ukuphuculwa kokunganyangeki, ukungcungcutheka okusezantsi, uzinzo oluphuculweyo (ukulingana okuphakathi kokulwa ukwanda), kunye nokuzinza ngokuchasene ne-oxidation. Umzekelo: Vespell sp-22.
I-10% ptfe kunye ne-15% yegrafu ngobunzima, i-SP-211
yongezwa kwi-resin yesiseko sesona sibeka iphantsi kwengqumbo ngaphezulu koluhlu olubanzi lweemeko zokusebenza. Ikwanxibe ngokuchasene nokuchasana ne-149 ° C (300 ° F). Izicelo eziqhelekileyo zibandakanya ukuntywila okanye ukutyholwa komgca kunye nezixhobo ezininzi zokunxiba kunye nokuxabana ezidweliswe apha ngasentla. Umzekelo: Vespel Sp-211.
I-15% ye-molly (i-molybdenum ilahlekile i-Lubreant eqinileyo), i-SP-3
Ukulungiselela ukudinwa kunye nokuchasana nokuchasana ne-vacuum kunye nezinye iindawo ezifumaneka kumanzi apho igrafu iyinyani. Izicelo eziqhelekileyo ziquka amatywina, iibherithi ezicacileyo, iigiya, kunye nezinye iindawo ezinxibe indawo engaphandle, i-Ultra-viam okanye izicelo ezomileyo. Umzekelo: Vespel SP-3.
