DMAc cu a sangmi polymer sernak ah a hrampi a si, a bik in a fekmi hri le zukcawl sernak ah:
Aramid Fibers:
Aramid fibers (tahchunhnak ah, Kevlar®) sernak ah, DMAc cu polyamide polymerization caah thlennak a si, cu nih cun meithal kuan, vanlawng fonhmi le riantuannak hri ah hmanmi a fek tukmi thilri sernak a tuah khawh. Tahchunhnak ah, US ralvennak riantuantu hna nih DMAc kha 3,600 MPa nak tam a tthawnnak a ngeimi aramid hri chuah khawhnak dingah an i bochan.
Polyimide Films:
Polyimide (PI) zukcawl (tahchunhnak ah, Kapton®) sernak ah hmanmi, DMAc nih polyamic acid a chuahtertu thilri pawl kha a hrawk hna, cu nih cun zukcawl a thuhnak le a tthawnnak sining hna kha a dikthliar in uk khawhnak a tuah. Hi zukcawl hna hi a nemmi electronics (tahchunhnak ah, OLED langhternak, a nemmi PCBs) le mawtaw motor ah a lin tukmi khamnak ah a biapi tukmi an si.
Spandex le Synthetic Fibers:
Puan sernak ah (tahchunhnak ah, Asian spandex sehzung), DMAc nih polyurethane hri pawl thlennak a bawmh, cu nih cun lentecelhnak thilthuam le sii lei hnipuan caah hmanmi puan ah aa khatmi kauh le tthawnnak a pek.
2. Sii lei & Biotechnology: Thil cawhmi le thlennak thilri
Sii sernak:
DMAc cu sii lei thilri karlak le a cawlcangmi sii lei thilri (API) chuahnak ah a phunphun in hman khawhmi thilri bantukin rian a ttuan. Organic le inorganic compound pahnih a hrawk khawhnak nih a tlawmternak, a tthawnnak le a tthawnnak caah a ttha tukmi a siter. Tahchunhnak ah, European sii dawr hna ah antiretroviral sii (tahchunhnak ah, HIV protease inhibitors) sernak ah hman a si.
Sernak bawmhnak:
A cunglei ah hmanmi sii (e.g., cream, gel) ah, DMAc nih vun chungin lipophilic sii a luh khawhnak a ṭhanchoter, cu nih cun vun hman khawhnak a ṭhanchoter. Cun a fahnak a tlawm caah le minung pumsa he aa tlak caah (LD₅₀ > 3,000 mg/kg in vok) parenteral sii ah hman a si.
Biotech hmannak:
Biopharmaceutical sernak ah, DMAc cu chromatography tibantuk protein thianhnak ah hman a si, cu nih cun membrane protein pawl kha a cawhter hna i tthennak tthatnak a tthanchoter.
3. Electronics & Semiconductor Industry: Microfabrication caah a dikmi thlennak
Photoresist Hlohnak:
Semiconductor sernak ah, DMAc cu silicon wafer chungin a fekmi photoresist a tangmi hna hloh awkah a sangmi thianhnak ah hman a si. Epoxy - based photoresists caah a ttha tukmi a si caah nanolithography ah a herh tukmi a si (tahchunhnak ah, 3nm chip nodes caah EUV lithography).
OLED le Display sernak:
Organic light - emitting diodes (OLEDs) sernak ah, DMAc nih organic semiconductors le dopants pawl kha a hrawh hna, cu nih cun inkjet printing asiloah spin - coating hmangin aa khatmi thin - film deposition a tuah khawh. Korean display sertu hna nih micrometer tiang pixel ttha tein hmuh khawhnak ding caah DMAc an hman.
Electroplating le Etching:
Sui le dar caah electroplating ti kholhnak ah co-solvent rian a ttuan, a sangmi thilri chiahnak thiamnak (tahchunhnak ah, 3D ICs, fan - out wafer level thilri chiahnak) ah chiahmi thilri aa khatmi a tthanchoter.
4. Puan le savun thlennak: A hmunmi a phichuak
Synthetic Fiber Spinning:
Acrylic fiber sernak ah, DMAc nih a ttha lomi thilri (tahchunhnak ah, dimethylformamide, DMF) a thlen, pawngkam hnahnawhnak a niam deuhmi he aa tlukmi thilri a pek. European thilthuam sernak sehzung hna nih DMAc cu OEKO - TEX® Standard 100 nih a fehtermi pawngkam he aa remmi thil tuahnak ah an hman.
Savun Tanning:
Hlanlio tanning agents aiawh ah, DMAc nih thingthei tannins luh khawhnak a tthanter, thil mansung (tahchunhnak ah, Italian savun kutdonghrolh) caah a nem deuhmi, thaw a chuah khawh deuhmi savun a chuahter. A tlawmmi a tthawnnak nih tanning tuahnak hmun ah VOC chuahmi a zorter.
5. Riantuannak Thianhnak le Chuahnak: Tlamtlingnak le Himnak
Thir hriak:
Vanlawng le mawtaw sernak ah, DMAc nih a dikthliar in hmanmi thilri (tahchunhnak ah, turbine hri, engine thilri) chungin chiti, chiti, le a tangmi thilri pawl kha a hloh hna. A linnak sang (166°C) nih ultrasonic thianhnak chungah a tlawm bik ti a chuahter, cu nih cun thil cawhmi a zorter.
Thilnung chuahmi chuahnak:
Thilnung rong (e.g., algae chungin carotenoids) le thingram thilri chungin sii chuahnak ah hmanmi, DMAc nih aa tinhmi thilri hna i an riantuan ning a hrawk loin thim khawhmi thlennak a pek.
