Minda mikuru yekushandisa
1. Indasitiri yePolymer: Kugonesa Zvishandiso Zvepamusoro-soro
DMAc inokosha zvikuru mukugadzirwa kwemapolymers epamusoro, kunyanya mukugadzirwa kwemafibers ane simba guru:
Mafiber eAramid:
Mukugadzira machira earamid (semuenzaniso, Kevlar®), DMAc inoshanda semushonga wepolyamide polymerization, zvichigonesa kugadzirwa kwezvinhu zvakasimba kwazvo zvinoshandiswa mumavesti asingapindi mabara, zvinhu zvinosanganisa mhepo, uye tambo dzemaindasitiri. Semuenzaniso, makambani ekudzivirira ekuUS anovimba neDMAc kugadzira machira earamid ane simba rekudhonza rinodarika 3,600 MPa.
Mafirimu ePolyimide:
Inoshandiswa mukugadzira mafirimu epolyimide (PI) (semuenzaniso, Kapton®), DMAc inonyungudutsa polyamic acid precursors, zvichibvumira kudzora kwakanyatsojeka ukobvu hwefirimu uye hunhu hweoptical. Mafirimu aya akakosha mumagetsi anochinjika (semuenzaniso, OLED displays, flexible PCBs) uye insulation yekupisa kwakanyanya mumota dzemotokari.
Spandex uye Synthetic Fibers:
Mukugadzira machira (semuenzaniso, mafekitori eAsian spandex), DMac inobatsira kutenderera kwemafiber epolyurethane, ichiva nechokwadi chekuti dhayamita uye kutwasuka kwakafanana mumachira anoshandiswa pazvipfeko zvemitambo uye zvipfeko zvekumanikidza zvekurapa.
2. Mishonga & Biotechnology: Switch uye Reaction Medium
Kugadzirwa Kwemishonga:
DMac inoshanda semushonga unonyungudutsa mumishonga inosanganisa mishonga uye kugadzirwa kwemishonga inoshanda (API). Kugona kwayo kunyungudutsa mishonga yeorganic neyeinorganic kunoita kuti ive yakakodzera pakuumbwa kwemvura, kutenderera kwemvura, uye kuita oxidation. Semuenzaniso, inoshandiswa mukugadzirwa kwemishonga inorwisa mabhakitiriya (semuenzaniso, HIV protease inhibitors) munzvimbo dzemishonga dzekuEurope.
Rutsigiro rweKugadzira:
Mumishonga inoiswa pamusoro peganda (semuenzaniso, makirimu, majeli), DMac inowedzera kupinda kwemishonga inouraya mafuta mumuviri kuburikidza neganda, zvichivandudza kuwanikwa kwemafuta mumuviri. Inoshandiswawo mumishonga inobvisa mafuta mumuviri nekuda kwehupfu hushoma uye kuenderana kwayo nemuviri wemunhu (LD₅₀ > 3,000 mg/kg mumakonzo).
Mashandisirwo eBiotech:
Mukugadzira mishonga yemishonga, DMac inoshandiswa mukuchenesa mapuroteni, senge chromatography, kunyungudutsa mapuroteni emukati uye kuvandudza kushanda zvakanaka kwekupatsanurana.
3. Indasitiri yeElectronics & Semiconductor: Kugadzirisa Kwakakodzera Kwekugadzira Zvinhu Zvidiki
Kubviswa kwePhotoresist:
Mukugadzira semiconductor, DMAc inoshandiswa mukuchenesa kwepamusoro kubvisa marara ekudzivirira kupenya kubva muma silicon wafers. Kusimba kwayo kwakanyanya kwe epoxy-based photoresists kunoita kuti ive yakakosha mu nanolithography (semuenzaniso, EUV lithography ye 3nm chip nodes).
Kugadzira OLED uye Display:
Mukugadzira ma organic light - emitting diodes (OLEDs), DMac inonyungudutsa organic semiconductors nema dopants, zvichiita kuti firimu rionekwe rakatetepa kuburikidza ne inkjet printing kana spin - coating. Vagadziri veKorea vanoshandisa DMac kuti vawane pixel chaiyo kusvika pa micrometer scales.
Kuisa neElectroplating uye Kucheka:
Inoshanda semusanganiswa wezvinhu zvinoshandiswa mumabhati ekugadzira goridhe nemhangura, ichivandudza kufanana kwedhipoziti mumatekinoroji epamusoro ekurongedza (semuenzaniso, maIC e3D, kurongedza kwewafer level fan-out).
4. Kugadziriswa Kwemachira Nedehwe: Mhinduro Dzinogarika
Kutenderera kweFiber yeSintetiki:
Mukugadzira machira e acrylic, DMAc inotsiva zvinonyungudutsa zvine chepfu (semuenzaniso, dimethylformamide, DMF), zvichipa simba rakaenzana uye zvine mhedzisiro yakaderera kune zvakatipoteredza. Makambani ekugadzira machira ekuEurope anoshandisa DMAc mumabasa anochengetedza nharaunda akabvumidzwa neOEKO - TEX® Standard 100.
Kuchenesa Dehwe:
Sechinotsiva zvinhu zvechinyakare zvekutsvukisa ganda, DMAc inowedzera kupinda kwe tannins dzemuriwo, zvichiita kuti dehwe rakapfava uye ripenye zvakanaka pazvinhu zveumbozha (semuenzaniso, mabhegi eganda ekuItaly). Kusasimba kwayo kushoma kunoderedza kuburitswa kweVOC munzvimbo dzekutsvukisa ganda.
5. Kuchenesa nekubvisa maindasitiri: Kushanda zvakanaka uye kuchengetedzeka
Kubvisa mafuta nesimbi:
Mumaindasitiri emuchadenga nemotokari, DMAc inobvisa mafuta, mafuta, uye zvinosara zveflux kubva muzvikamu zvakanyatsonaka (semuenzaniso, mashizha eturbine, zvikamu zveinjini). Kufashaira kwayo kwakanyanya (166°C) kunoita kuti pave nekudziya kushoma panguva yekuchenesa kweultrasonic, zvichideredza kurasikirwa kwe solvent.
Kubviswa Kwechisikigo:
Inoshandiswa mukubvisa pigments dzechisikigo (semuenzaniso, carotenoids kubva mualgae) uye mishonga kubva mumiti, DMAc inopa solvency yakasarudzwa pasina kukanganisa bioactivity yemakemikari anotarisirwa.
