Polyimides (PI) vane hombe-perincmers polymers yemolly masoja ane maviri nitrogen (n) -Boode acl mapoka (c = o). Idzi polymers dzinozivikanwa nekuita kwavo kwakanyanya kupisa mune 400-500 ° C mhando pamwe nekupokana kwavo kwemakemikari.
Mune akawanda maindasitiri ekushandisa, anoshandiswa kutsiva kushandiswa kwechinyakare kwegirazi, simbi uye kunyange simbi.
Polyimides ane zvakanakisa manhamba emhando uye saka anogona kushandiswa mune zvekushandisa izvo zvinoda zvinhu zvakasimba zveganda zvakasimba, semuenzaniso:
Yakakwira tembiricha inodzivirira mafuta masero
Flat Panel Kuratidzira
Aerospace application
MaMakemikari neMagisitiri Maindasitiri
uye zvinoshandiswa nemauto akasiyana
Ivo vanoshandiswa kunge mapurasitiki, mafirimu, vanorereta resins, vachisimbisa machira uye yakakwirira-tembiricha yekuomarara.
Polyimides anowanikwa mumhando mbiri: thermosms uye thermoplastic.
Pi inogona kukamurwa kuva ongororo uye thermoplastic, inogona kukamurwa muPoly (tetremethyle tetrabimide) (PMI), Polyamide monimoimide (PI), etc., etc.
PMmi mu 1.8 MPPA Load Heat kukanganisa tembiricha ye360 ℃, inogona kushandiswa mamiriro ezvinhu akakosha ezvikamu zvakanyanyisa, zvisimbiso, blower zvinyararire, etc., zvinogona zvakare kushandiswa mukubatana neyemvura ambime Nhamba dzeValve, Jet Injini Mafuta Anopa Supply system zvikamu.
PEI ine zvimiro zvakanakisa zvekushandisa, kurwisa kwesimbe Shandiswa kune nzira yeWelding uye zvimwe zvinhu zvakasanganiswa mumagetsi uye magetsi, Aerospace, emagetsi, midziyo yekurapa uye mamwe maindasitiri anoshandiswa zvakanyanya.
Simba rePAI rakanyanya pakati pePurasitiki dziripo, Simba reChinese ndeye 190 MPa, Simba rakakotama riri 250 MPA, uye kupisa kupisa kwakakwirira kusvika 274 ℃ pasi pemutoro we1,8 mpa. Pai ane simba rakanaka rekushandura kuora uye electromagform pakupisa uye mafambiro akanyanya, uye zvinonyanya kushandiswa kune midziyo, fani, uye nemakwenzi ekuparadzanisa emitambo, nezvimwewo, uye Inogona kushandiswa kune zvigadzirwa zvinoshamisa zveAircrafts, turansmitance zvigadzirwa, uye zvimwe zvinoshandiswa, uye zvinogona kushandiswa mukugadzirwa kwemagetsi zvishandiso zvemagetsi. Izvo zvinonyanya kushandiswa kune magiya, fani uye kupatsanurana kwemahombekombe emota, etc. Iyo inogona zvakare kushandiswa kune zvinoshamisa zvekushandisa, zvinhu zvinogamuchirwa uye zvigadzirwa zvemhando dzedenga.
