Polyimide siab thiab kev Polyimide

Vim hais tias cov polyimide nyob rau hauv kev kawm ntawv thiab cov Science News for KIDS hluavtaws yam ntxwv, muaj ntau lub polymer, nws nrhiav tsis tau xws li polyimide uas zoo li no ntau hom ntaub ntawv, tab sis kuj nyob rau hauv txhua nam qhia tau hais tias koj tsis tshua muaj neeg ntawv.

1, zaj duab xis: yog ib qhov earliest coj mus muag polyimide, siv kom wrapping qhov khoom rwb thaiv tsev tsav thiab cable. Cov khoom tseem ceeb yog DuPont Kapton, Ube Upilex series thiab Kaneka Apical. Polyimide zaj duab xis thiab pob tshab ua roj teeb solar phaj mos.

2 cov xim: raws li insulating cov xim muaj hlau rau electromagnetic tus hlau, los yog ua ib siab kub resistant txheej.

3: paub ntau puas txaus rau Cheebtsam aerospace, aircraft thiab foob pob ua ntxaij. Yog ib qhov feem High School-kub yam khoom. Rau teb chaws USA supersonic airliner yeej npaj cov qauv siv ceev ua piv txwv yog 2.4M, davhlau thaum kub deg 177 ℃, txoj hauj lwm muab kev pab yuav tsum muaj 60000 h, tiam sis raws li ntaub ntawv tau nrhiav tau yam khoom 50% yog cob thermoplastic polyimide matrix carbon fiber siv tam composites, txhua aircraft yam li 30 t.

4. fiber ntau: elastic modulus tom qab carbon fiber ntau li lim ntaub, siab kub nruab nrab thiab tej tshuaj thiab mos txwv cov pov thawj, fireproof npuag.

5. ua npuas ncauj: siv ua npaws kub resistant insulating khoom tawg yooj yim.

6. yam xws li tshuab uas: thermosetting nrog thermoplastic, thermoplastic tau molding kuj yuav siv txhaj tshuaj molding los yog hloov molding. Mas siv rau qhov lubrication, sealing, rwb thaiv tsev ntaub ntawv thiab cov qauv. Thiab tau siv ntau tsav, tshuab textile, ntim tshuab, tshuab luam ntawv, bearings iav thiab tiv thaiv thiab ua yam..

7. nplaum: siv raws li qib-kub yam ntxwv nplaum. Guangcheng polyimide nplaum ua hauv cheebtsam uas kub insulating yas ntau lawm.

sib cais 8 membrane: vim muaj ntau roj sib cais, xws li hydrogen / nitrogen, nitrogen / pa, cov / nitrogen los yog methane thiab lwm yam hydrocarbons, tshem ya raws cua cov roj nyoos thiab cawv suab thaj uas. Kuj yuav siv tau raws li lub pervaporation membrane and ultrafiltration membrane. Vim hais tias cov polyimide hauv tsev kom sov ua hauj thiab organic kuab kuj, nrog kev RESPONSIBILITIES tshwj xeeb rau kev sib cais cov organic gases thiab haus kua kom ntau.

9.Photoresist:A photoresist tsis zoo thiab thaum nws zoo, qhov no yuav mus txog sub micron. Tus xim los yog xim rau zaj duab xis lim xim, yeej heev piv cov txheej txheem ua.

10. daim ntawv thov rau hauv tej dais microelectronic: siv cov dielectric txheej ntawm txheej rwb thaiv tsev, raws li ib tug laj txheej tsis tiv thaiv kom muaj kev nyuaj siab, zoo rau tus nqi ntawm cov khoom uas siv lawm. Li tiv txheej yuav txo cawv ntawm ib puag ncig ntawm cov ntaus ntawv, tiam sis kuj muaj cov nyhuv shielding ntawm ib - hais, qhov yuav txo los sis tshem tawm mos yuam kev ntaus ntawv (mos yuam kev).

11. kua siv lead ua tso saib tus neeg saib xyuas: Orientation orientation TN-LCD, SHN-LCD, TFT-CD polyimide thiab lub neej tom ntej ntawm lub ferroelectric siv lead ua kua zaub tus neeg saib xyuas khoom plays tseem.

12. Electro kho qhov muag khoom: siv waveguide passive los yog yam khoom rau cov ntaub ntawv kho qhov muag switching, yog polyimide uas muaj fluorine hauv cov kev sib txuas lus wavelength ntau pob tshab, cov polyimide ua chromophore substrate yuav ua kom cov stability ntawm cov khoom.

13. hluav taws xob thiab hauv kev lag luam: printed Circuit Court laug cam, rwb thaiv tsev ntaub ntawv, kub cable, thaiv terminals, thiab lwm yam nyob..
