Kev Lag Luam Kev Ntsuam Xyuas Polyimimide Zaj Duab Xis
Mar 17, 2025
Txheej txheem cej luam ntawm polyimide zaj duab xis (Pi Zaj Duab Xis)
Polyimide (PI) yog cov polymer muaj ib lub qauv immide hauv nws cov kab mob molecular. Nws zwm rau tsev neeg loj ntawm kev ua haujlwm siab polymers, nrog kev ua tau zoo PI cov ntaub ntawv muaj ntxhiab thiab Heterocyclic txheej ua lawv cov kab ke loj. PI muaj cov nplaim hluav taws xob siab tshaj plaws rating (Umm} 2}}) thiab cov khoom pov thawj, tshuaj lom neeg tawm tsam, thiab hluav taws xob tsis kam. Nws muaj dielectric constant ntawm 4. 0 ntawm 1 {}}}}}}}}}} Cov khoom no tseem nyob ruaj khov tshaj li qhov kub thiab txias ({{}} theem siab ntawm kev ua "ib qho ntawm cov kev cog lus encharing plastics ntawm lub xyoo pua 21st" thiab "qhov teeb meem solver." Nws yog feem ntau hais tias "tsis muaj polyimide, microelectronic niaj hnub yuav tsis muaj nyob," li PI cov ntaub ntawv zaum ntawm lub ntsiab lus ntawm cov khoom siv polymer hierarchy.
Cov Zaj Duab Xis Polyimide (Pi Zaj Duab Xis)
Pi Zaj Duab Xis muaj cov khoom tshwj xeeb, Dielectric cov khoom, tshuaj lom neeg ruaj khov, thiab zoo tshaj plaws rau hluav taws xob, xeb, thiab huab cua sov siab. Nws tau suav hais tias yog qhov zoo tshaj plaws-ua tau zoo engineering engineering engineering polymer cov ntaub ntawv thoob ntiaj teb thiab feem ntau hu ua "Zaj duab xis." Nrog nrog carbon fiber thiab aramid fiber ntau, PI zaj duab xis yog ib qho ntawm peb cov khoom siv polymer uas tseem ceeb tshaj plaws kev lag luam ntawm cov kev lag luam qib highch-tech hauv Suav teb.
Cov txheej txheem tsim qauv ntawm polyimide zaj duab xis (Pi Zaj Duab Xis)
Ua ntej tshaj tawm Imidization, PI zaj duab xis yuav tsum tau tsim ua ntej rau hauv daim ntawv sau ua, suav nrog kev ua kom ncab), xws li ntawv ci txheej), tsuag, extrusion, thiab kev tso tawm. Qhov kev xaiv ntawm kev ua cov txheej txheem loj heev cuam tshuam rau cov yeeb yaj kiab cov khoom thiab ntau lawm kev ua tau zoo. Ntawm cov hau kev no, casting thiab casting-ncab yog cov feem ntau siv. Lub tom kawg yog nyiam rau kev tsim cov kev ua tau zoo PI yeeb yaj kiab. Hauv Suav teb, ob txoj hauv kev casting thiab impregnation tau tsim zoo, txawm hais tias txoj kev impregnation tau tshwm sim vim nws lub peev txheej insulation. Cov txuj ci siab ntau xws li txau, extrusion, thiab kev faib tawm, tseem tseem nyob hauv Japanese tswj hwm ntawm xyoo 2013.
Tam sim no, ob txoj kev imidization thawj zaug muaj: thermal imidization thiab tshuaj imidization.
Thermal imidizationKoom nrog cov kua kub polyamic acid rau qhov ntsuas kub tshwj xeeb, ntxias lub cev qhuav dej thiab kev sib deev.
Tshuaj imidizationinvolves adding a dehydrating agent and catalyst to polyamic acid at temperatures below -5 degree , rapidly mixing, and then heating to promote dehydration and cyclization.
Piv nrog cov tshuaj lom neeg tsis haum, lub thermal txoj kev yooj yim nyob rau hauv cov ntsiab lus thiab cov cuab yeej siv tab sis tsim cov tshuaj, ua rau nws tsis zoo rau hauv hluav taws xob-qib PI yeeb yaj kiab. Ua ntej xyoo 2014, feem ntau suav cov tuam ntxhab feem ntau, whereas yuav luag txhua qhov loj PI cov teb chaws cov tuam ntxhab tau hloov mus rau kev siv tshuaj lom neeg. Cov tshiab tsim 180- tuj pi zaj duab xis txheej txheem, ua kom cov khoom siv tshiab ua ke rau cov ntawv thov kev thauj mus los.
