Premium Dimethylacetamide (DMAc): Gin ma tiyo maber ma ki lwongo ni Polar Solvent pi tic ma dongo
Kabedo ma pire tek me tic kwede
1. Polymer Industry: weko jami ma tiyo maber
DMAc obedo gin ma pire tek i yubu jami ma ki lwongo ni advanced polymers, tutwale i yubu jami ma tek ki filim:
Aramid Fibers:
I yubu jami ma ki lwongo ni aramid fibers (me labolle, Kevlar®), DMAc tiyo calo gin ma ki lwongo ni solvent pi polyamide polymerization, ma miyo twero me yubu jami ma tek ma ki tiyo kwede i bulletproof vests, aerospace composites, ki industrial ropes. Me labolle, lutic me US gi jenge i kom DMAc me yubu jami ma ki lwongo ni aramid ma tye ki teko ma kato 3,600 MPa.
Polyimide Films:
Ki tiiyo kwede me yubu polyimide (PI) films (e.g., Kapton®), DMAc kwanyo polyamic acid precursors, ma miyo twero me doro pek pa film ki kit ma nen kwede. Filim magi pire tek i jami ma tiyo ki mac (me labolle, nyutu OLED, PCBs ma twero loko) ki gwoko lyeto ma malo i kom motoka.
Spandex ki Synthetic Fibers:
I yubu bongo (me labolle, ka yubu jami ma ki lwongo ni spandex i Asia), DMAc konyo yubu jami ma ki lwongo ni polyurethane fibers, ma miyo diameter ki elasticity rom i bongo ma ki tiyo kwede me yubu bongo me tuku ki bongo me yot kom.
2. Yat ki jami makwo: Gin ma ki tiyo kwede me juku ki gin ma kelo alokaloka
Kit me yubu yadi:
DMAc tiyo calo gin ma twero juku jami mapol i kin jami ma ki tiyo kwede i ot yat ki jami ma tiyo i ot yat (API). Ker ne me juku jami ma kwo ki ma pe kwo miyo bedo maber pi condensation, cyclization, ki oxidation reactions. Me labolle, ki tiiyo kwede me yubu yadi ma gengo kwidi two jonyo (me labolle, jami ma gengo kwidi two jonyo) i ot yat me lobo Europe.
Kony me yubu jami:
I kom jami ma ki tiyo kwede i kom dano (me labolle, moo, gel), DMAc medo rwom me donyo pa yadi ma mako moo i del kom, ma weko bedo maber. Ki tiyo kwede bene i yat ma ki lwongo ni parenteral pi teko ne manok ki rwate ki kom dano (LD₅₀ > 3,000 mg/kg i kom oyoo).
Tic ki jami makwo:
I yubu jami ma konyo kom, DMAc ki tiyo kwede i yub me yubu protein, ma calo chromatography, me yubu protein ma i kom ler ki medo rwom me poko ne.
3. Tic me jami ma tiyo ki mac ki jami ma tiyo ki mac: gin ma ki tiyo kwede me yubu jami ma tiino tino
Kwanyo jami ma kwanyo lero:
I yubu jami ma ki lwongo ni semiconductor, DMAc ki tiyo kwede i yub me lwoko jami ma malo me kwanyo jami ma odong ki i silicon wafers. Kit ma en twero cobo kwede jami ma ki lwongo ni epoxy - based photoresists miyo en bedo gin ma pire tek i nanolithography (me labolle, EUV lithography pi 3nm chip nodes).
OLED ki yubu jami ma ki nyutu:
I yubu jami ma cwalo mac (OLEDs), DMAc poko jami ma cwalo mac ki dopants, ma weko jami ma ki lwongo ni thin - film deposition bedo marom ki inkjet printing onyo spin - coating. Luyub jami ma ki nyutu i Korea tiyo ki DMAc me nongo rwom me pixel ma rwate ki micrometer.
Electroplating ki Etching:
Tiiyo calo gin ma ki lwongo ni co - solvent i electroplating baths pi jabu ki copper, ma weko rwom me depot bedo marom i diro me keto jami ma malo (me labolle, 3D ICs, fan - out wafer level packaging).
4. Yubu bongo ki del ler: yoo ma twero bedo pi kare malac
Yubu jami ma ki yubu ki jami ma ki yubu:
I yubu jami ma ki lwongo ni acrylic fibers, DMAc loko jami ma kelo two (me labolle, dimethylformamide, DMF), ma miyo jami ma kelo two ma rom ki balo kwo pa dano. Dul ma yubu bongo me lobo Europe tiyo ki DMAc i yoo ma pe balo kwo pa dano ma ki moko ki OEKO - TEX® Standard 100.
Kit ma ki yubu kwede del ler:
Ma calo gin ma ki loko i kom jami ma ki tiyo kwede me yubu del kom, DMAc medo rwom me donyo pa tannins ma aa ki i poto, ma miyo del kom ma yom, ma weko yamo kato maber pi jami ma wel ne tek (me labolle, kicar ma ki yubu ki del ler me Italy). Kit ma en twero loko kwede piny dwoko piny yamo ma ki lwongo ni VOC i ka yubu del kom.
5. Yub me lwoko ki kwanyo jami: tic maber ki ber bedo
kwanyo moo i kom nyonyo:
I yub me yamo ki motoka, DMAc kwanyo moo, moo, ki jami ma odong ki i kom jami ma ki tiyo kwede (me labolle, jami ma ki lwongo ni turbine blades, jami ma i engine). Kabedo ne ma malo me lyeto (166°C) miyo pii ma mol manok i kare me lwoko ki ultrasonic, ma dwoko piny rweny pa gin ma ki lwongo ni solvent.
Kwanyo jami ma ki yubu ki lobo:
Ki tiiyo kwede me kwanyo rangi del kom (me labolle, carotenoids ki i kom lum) ki yadi ki i kom jami ma ki pito, DMAc miiyo teko ma ki yero labongo balo tic pa jami ma ki yubu.
