3. Industry Elektronik & Semi-Konduktor: Solvant laaɓtuɗo ngam Mikrofabrikaasiyoŋ
Ittugol fotoresist:
E nder peewnugol semmbeeji, DMAc ina huutoree e golle laɓɓingol jahruɗe yeeso ngam ittude heddiiɓe e fotosintesis tiiɗɓe e nder laylayti silikon. Solɓe maggal toowngal wonande fotoresisteeji baɗɗi epoksi ina addana ɗum wonde huunde nde alaa ko nafata e nanolitografi (yeru, litogaraafi EUV wonande nodule 3nm).
OLED e Pewnugol Kollitgol:
E nder peewnugol diyooji gonɗi e annoore (OLED), DMAc ina ɓuuɓna semi-kondukteeruuji e dopanuuji gonɗi e nder weeyo, ina addana ɗum en waɗde mbaydiiji ɓuuɓɗi gooti e mbaydi tappirde inkjet walla spin - coating. Pewnitooɓe hollirde Koree ina kuutoroo DMAc ngam heɓde laaɓal pixel haa e tolnooji mikroomeeteer.
Elektroplating e Ƴeewndo:
Ina huutoroo co - solvant e nder batte electroplating ngam kaŋŋe e njamndi, ɓeyda yuɓɓo deposit e nder karallaagal paaspooruuji jahduɗi e jamaanu (yeru, ICs 3D, paaspooruuji to bannge wafer fan - out).
4. Pewnugol mbaylaandi e ɓalli : kuule duumotooɗe
Fiɓnde sintetik :
E nder peewnugol fiɓnde akrilik, DMAc lomtotoo ko solɓe ɓurɓe tookeede (yeru, dimetilformamide, DMF), ina rokka solɓe nannduɓe e batte ɓurɗe famɗude e weeyo. Miliyoŋaaji mbaylaandi Orop ina kuutoroo DMAc e nder golle baɗɗe faayiida ɗe OEKO - TEX® Standard 100 seedtini.
Tanning leɗɗe:
Ko lomto tannirɗe gaadanteeje, DMAc ina ɓeyda naatgol tannin leɗɗe, ina addana ɗum leppi ɓurɗi softude, ɓurɗi foofde ngam waɗde geɗe teskinɗe (yeru, saakuuji leppi Itaali). Ko famɗi fof, ɓuuɓri maggal ina usta VOC e nder nokkuuji tan.
5. Laɓɓingol e ittugol gollorɗe : Ƴellitaare e kisal
Degreesing njamndi:
E nder gollorɗe aerospace e otooji, DMAc ina itta nebam, ƴiiƴam, e heddiiɓe e ɓuuɓri e nder geɗe laaɓtuɗe (yeru, ƴiye turbineeji, geɗe moteriiji). Toɓɓere maggal toownde (166°C) ina addana ɗum ɓuuɓde seeɗa e nder laɓɓingol ultrasonic, ina usta ŋakkeende solvant.
Ittugol geɗe tawaaɗe:
Huutortee ko e ittugol pigmentaaji naftooji (yeru, karotenoid e nder algaaji) e leɗɗe cafrorteeɗe e nder geɗe leɗɗe, DMAc ina rokka solde cuɓaaɗo tawa bonnataa bioactivité de composés targets.
