I-Dimethylacetamide Lesetulu (i-DMAc): Sisombululi Se-Polar Lesetulu - Lesisebentako Setimboni Letitfutfukile
Tindzawo Letinkhulu Tesicelo
1. Imboni Ye-Polymer: Kunika Emandla Tintfo Letisetulu - Tekusebenta
I-DMAc litje lekusimisa ekukhiciteni ema-polymers lahamba embili, ikakhulukati ekuhlanganisweni kwetintfo letinemandla lamakhulu kanye nemafilimu:
Imicu ye-Aramid:
Ekukhiciteni imicu ye aramid (sib., Kevlar®), iDMAc isebenta njengesicibilikisi se polyamide polymerization, kwenta kutsi kwakhiwe tintfo leticinile kakhulu letisetjentiswa kuma vest langahlaselwa tinhlamvu, tintfo letihlangene temoya, kanye netintsambo tetimboni. Sibonelo, bosonkontileka bekuvikela base US batsembele ku DMAc kutsi bakhicite imicu ye aramid lenemandla ekucindzetela langetulu kwa 3,600 MPa.
Emafilimu e-Polyimide:
Isetjentiswa ekukhiciteni emafilimu e-polyimide (PI) (sib., i-Kapton®), i-DMAc incibilikisa tintfo letihamba embili te-polyamic acid, kuvumela kulawula lokucinile kwekucina kwefilimu kanye netimphahla tekubuka. Lamafilimu abalulekile ku-elekthronikhi legucugucukako (sib., imibukiso ye-OLED, ema-PCB lagucugucukako) kanye nekuvikela lokusetulu - kwekushisa etimoto tetimoto.
I-Spandex kanye nemicu leyentiwe:
Ekukhiciteni tindvwangu (sib., titjalo te spandex tase Asia), iDMAc yenta kutsi kubelula kujikeleta imicu ye polyurethane, kucinisekisa bukhulu lobufanako kanye nekugucuka etindvwangu letisetjentiselwa timphahla tekudlala kanye netimphahla tekucindzetela tekwelapha.
2. Imitsi & I-Biotechnology: Indlela Yekuncibilikisa Nekuphendvula
Kuhlanganiswa kwetidzakamiva:
I-DMAc isebenta njengesincibilikisi lesihlukahlukene etintfweni letisemkhatsini temitsi kanye nekukhicita sitsako semitsi lesisebentako (API). Likhono layo lekuncibilikisa kokubili lokuphilako nalokungaphili kwenta kutsi kube kuhle kwekuhlanganiswa, kujikeleta, kanye nekuphendvula kwe oxidation. Sibonelo, isetjentiswa ekuhlanganisweni kwemitsi yekulwa neligciwane lesandulelangculazi (sib., tivimbeli te-HIV protease) etikhungweni temisebenti yemitsi yaseYurophu.
Kusekelwa Kwekwakheka:
Ekwakhiweni kwetindzawo (sib., emakhilimu, emajeli), iDMAc yenta ncono kungena kwemitsi ye lipophilic ngesikhumba, kwenta ncono kutfolakala kwetilwane. Iphindze isetjentiswe etisombululweni te parenteral ngebuthi bayo lobuphansi kanye nekuhambisana nemtimba wemuntfu (LD50 > 3,000 mg/kg kumagundvwane).
Ticelo te-Biotech:
Ekukhiciteni imitsi yekuphila, iDMAc isetjentiswa etinchubeni tekuhlanta emaprotein, njenge chromatography, kwentela kuncibilikisa emaprotein elucwencweni kanye nekutfutfukisa kusebenta kahle kwekuhlukanisa.
3. Imboni Ye-elekthronikhi Ne-Semiconductor: Sisombululo Lesicinile Sekukhicita Lokuncane
Kususwa kwe-Photoresist:
Ekwakhiweni kwe-semiconductor, i-DMAc isetjentiswa etinchubeni tekuhlanta letisezingeni lelisetulu kususa tinsalela te-photoresist letinenkhani kusuka kuma-wafers e-silicon. Kukhokha kwayo lokusetulu kwe-epoxy - lokusekelwe e-photoresists kwenta kutsi kube yintfo lebalulekile ku-nanolithography (sib., i-EUV lithography ye-3nm chip nodes).
OLED kanye nekukhicita kwekubonisa:
Ekukhiciteni ema-diode lakhipha kukhanya lokuphilako (ema-OLED), i-DMAc incibilikisa ema-semiconductors laphilako kanye ne-dopants, kwenta kutsi kube nekufakwa kwefilimu lencane lefanako ngekushicilela nge-inkjet noma ngekugcobisa nge-spin. Bakhiciti bekubonisa baseKorea basebentisa i-DMAc kute bazuze kuciniseka kwemaphikseli phansi kuya etikalini te-micrometer.
Kufaka gezi kanye nekubhala:
Isebenta njenge co - solvent ekugezeni kwe-electroplating yeligolide nelitfusi, kwenta ncono kufana kwemadiphozithi ebuchwephesheni bekupakisha lobutfutfukile (sib., ema-IC e-3D, kupakisha kwelizinga le-wafer ye-fan - out).
4. Kucubungula Tindvwangu Nesikhumba: Tisombululo Letisimeme
Kuphotsa I-Fiber Yekwentiwa:
Ekukhiciteni imicu ye acrylic, iDMAc itsatsa sikhundla setinhlayiya letinebuthi kakhulu (sib., dimethylformamide, iDMF), iniketa kuncibilikisa lokufanako lokunemtselela lophansi wemvelo. Tigayo tetindvwangu taseYurophu tisebentisa i-DMAc etinchubeni letilungele imvelo leticinisekisiwe yi-OEKO - TEX® Standard 100.
Kushisa Sikhumba:
Njengesikhundla setintfo tekushisa tendzabuko, iDMAc yenta ncono kungena kwema tannins etibhidvo, kukhicita sikhumba lesitsambile, lesiphefumulako kakhulu setintfo tekunetisa (sib., tikhwama tesikhumba tase Italy). Kugucugucuka kwayo lokuphansi kunciphisa kukhishwa kwe VOC etindzaweni tekushukela.
5. Kuhlanta Nekukhipha Timboni: Kusebenta Kahle Nekuphepha
Kususa Emafutsa Ensimbi:
Etimbonini te-aerospace kanye netimoto, i-DMAc isusa oyili, emafutsa, kanye netinsalela te-flux kusuka etincenyeni letinembile (sib., ema-turbine blades, tincenye tenjini). Indzawo yayo lesetulu yekubila (166°C) icinisekisa kuhhwamuka lokuncane ngesikhatsi sekuhlanta nge ultrasonic, kunciphisa kulahlekelwa kwe solvent.
Kukhishwa kwemkhicito wemvelo:
Isetjentiswa ekukhipheni imibala yemvelo (sib., ema carotenoids kusuka ku algae) kanye nemitsi kusuka etintfweni tetitjalo, iDMAc iniketa kukhetsa kukhokha ngaphandle kwekucedza i-bioactivity yemakhompawundi lahlosiwe.
