Pai plastics yakatanga kuvandudzwa muna 1964 neiyo ammoco research Institute muNapervill, USA muna 1965, muedzo wekusimbisa pendi, uye muna 1971 chigadzirwa chakashongedzwa pasi pezita rekutengeserana.
Pai (polyamide milie terylene / torlon) inowanzogadzirwa nePlongcononsation ye phenyltrimellitic azhydride uye diisocyanate mune DMF solution. Nekuda kweiyo yakagadzikana inonhuhwirira heterocyclic chimiro mumarara aro, pai inoratidza kupisa uye yakaderera-kupisa kudzikisira kusingaenzaniswi nedzimwe polymer zvinhu
Dzidza nezvehunhu hwePAI:
High Tembiricha Kudzivisa:
Iyo inoratidzira yakanakisa manhamba emhando uye dimensional kugadzikana munzvimbo dzakasimba dzekushisa. Iyo ine yakanakisa dimensional kugadzikana mune 250 ° C tembiricha, uye inokwanisa kusvika kusvika 275 ° C (525 ° F) uchiri kuchengeta
Kuoma kwayo, simba rakakura uye kuomarara.
Kuramba kuBrasion:
Zvakanakisa kupfeka kuramba mune zvese zvakaoma uye zvakaoma nharaunda, izvo zvinogona kuwedzeredzwa nekuwedzera kweCarbon fiber uye polymeric lubricants yakadai sePTFE.
Simba rakakwirira:
Simba rakakwirira, kusindimara uye kukanganisa kurwisa kunoita kuti zvive zvakanakira zvimiti uye zvinoshandiswa.
Kumakemikari kurwisa:
Inoratidza huwandu hwakawanda hwekudzivisa kwemakemikari kune yakasimba acids, alkalis uye yakawanda organics.
Creep kuramba:
Inoratidza yakanyanya kukwira kukwira simba uye inochengetedza michina yayo yekuita kunyange pakupisa kwakanyanya.
Yakaderera coefficient yemutsetse edzinza yekuwedzera (CLTE):
Iyo yakaderera coefficient yemutsara yekuwedzera yekuwedzera (CLTE) inobvumira shanduko diki dzekupanduka panguva yekutsvagisa, zvichiita kuti zviite zvakaringana zvinhu zvakanyatsojeka.
Kuzvisimbisa:
Zvivakwa zvekuzvifunga zvinobvuma kuti zviite kushanda pasi pemamiriro ezvinhu asina kukwana, kuderedza kupokana uye kupfeka.
Kufa kwakaderera:
Yakavezwa yakaderera yekufa, ichiita kuti iite kuti iwane kushandiswa mune application inoda kuchengetedza moto.
Radiation Resistance:
Ane Superors Ristance kune yakakwira simba radiation, ichiita kuti iite yakakodzera kushandiswa munzvimbo dzakakwirira dzekurara.
Magetsi Kunzwa:
Inorara zvakakwirira zvekusimbisa zvivakwa, zvichiita kuti zviite kuti zvive kushandiswa mune zvemagetsi zvikamu uye zvigadzirwa zvemagetsi.
Kugadziriswa:
Inogona kuumbwa nejekiseni kuumbwa uye mamwe maitiro ekuumba akasiyana-siyana emhando dzakaomarara dzezvigadzirwa zvakanyanyisa, kunyatsogadzirwa kwekugadzira.
Pai zvinhu zvine hunhu hwekutsigira aya kuita kuti pai ive yakakodzera sarudzo yezvakawanda zvinodiwa zvekushandisa, kunyanya mukuda kwekushisa kwekushisa kwemvura uye nekunyora kwemakwikwi ekushandisa zvakanyanya kushandiswa zvakanyanya.
Nzvimbo dzekushandisa dzePlastic zvinhu
Pai (polyamide-imidee) ipurasitiki yeinjiniya ine zvinhu zvakanakisa uye zvinoshandiswa mune dzakasiyana siyana dzekushandisa. Iyi inotevera mienzaniso yeimwe yenzvimbo iyo pai iyo pamba ichishandiswa:
1.lighter tsvimbo
Vatengi vakagadziriswa vasina-standard zvikamu, kushandiswa kwakananga hakuna kujeka, kunofanirwa kuve maitiro ePAI zvinhu, sarudza zvinhu izvi.
a. Pai yakarera tsvimbo ine high sitivity uye kuramba kune yakanyanya kupisa uye nekumanikidza kwakanyanya, mukuda kwekunyora-voltage discharge discharge zvinyorwa zvabuda. Semuenzaniso, mune yakatungamirwa waya waya waya waya yairera, paizi tsvimbo inoshandiswa kuburitsa yakakwirira-kumanikidza, iyo yegoridhe waya, waya yemhangura,
Alloy Wire uye mamwe manyoro akanyungudika kubva kune inopisa bhora, maitiro aya anozivikanwa zvakare seEfo (emagetsi munda oxidation) basa.
b. Pai zvisizvo caltive yemagetsi maitiro, Simba reChinera uye kuomarara kwerudzi uye humwe hunhu hunoita kuti zvive mukushandiswa kwetsvimbo yakareruka ine mukana. Semuenzaniso, magetsi akakwirira ekuita uye yakakwirira yeStentile Simba rePAI zvinhu zvinoita kuti ive yakagadzikana mune yakakwira-voltage discharge maitiro.
Unogona kushandira zvine hunyanzvi muzvipfuyo zvepamusoro-soro, nepo kuomarara kwaro kweblue kunopa basa rakanaka rekupokana.
c. Maindasitiri ekushandisa:
Pai Ligher Rods anoshandiswa mune yakakwirira-simba nzvimbo munzvimbo dzakadai semapu maindasitiri uye maburi. Aya anokambaira anowanzove neyekudzvanya, tsvimbo yakareruka, uye tambo yekuvhara. Tembiricha yakakwira uye yakanyanya kudzvinyirira kuramba kwePAI zvinhu zvinoita
Pai zvidzidziso zvekushambadzira kune tembiricha yakakwira uye yakanyanya kudzvinyirira inozvitendera kuita zvakanaka mune idzi nzvimbo dzakakwirira-tembiricha ....
d. Wire Kubatira Kugadziriswa: PI INGETION TODS zvakare inoshandiswa zvakare kune waya yekubatanidza waya yekubatanidza. Wese waya maruva anovhenekera anowanikwa pamusika uye akagadziridzwa kuti adzorere. Tsvimbo idzi dzinoita basa rinokosha mukuita kweWalking, inoona mhando yeld.
Vanotamba basa rinokosha mukuita mari, vanoona kunaka uye kugadzikana kweWeld.
2. Aerospace:
Zvigadzirwa zvePAI zvine hunyanzvi hwekuramba uye electromaggnetic zvivakwa pakupisa kwakanyanya uye kwakakwirira nguva zhinji, uye zvinogona kushandiswa sezvinhu zvekushandisa uye zvigadzirwa zvemashiripiti uye zvigadzirwa zvemagoma.
3.Umotomotive:
Pai Zvinyorwa zvinoshandiswawo muindasitiri yemotokari, kunyanya yekugadzira yeakakwirira tembiricha uye vanopfeka zvisimbiso, senge zvisimbiso, pombi uye zviumbwa uye mabhenji uye bhururu.
4.Semicononductor uye microyelectronics:
Pai Zvigadzirwa zvinoshandiswa Semiconductor bvunzo zvikamu, kugadzirisa mainests, Wafer Combs, microelectronic ic Bvunzo dzinoongororwa uye mafambisirwo.
5. Mechanics uye Chimiro zvikamu:
Pai Zvigadzirwa zvinowanzoshandiswa mugadzirwa yezvikamu zvakadai semagiya, mahedhiyo, uye kupatsanura shaya dzepikicha nekuda kwesimba ravo rakakwirira uye kupfeka kupokana.
