I-Premium Dimethylacetamide (DMAc): I-Polar Solvent esebenza kuhle khulu yamabubulo athuthukileko
Iindawo ezikulu zokusebenza
1. Ibubulo le-Polymer: Ukwenza izinto ezisebenza kuhle khulu
I-DMAc lilitshe eliyisisekelo ekukhiqizeni ama-polymer athuthukileko, khulukhulu ekuhlanganisweni kwemicu enamandla amakhulu namafilimu:
Imicu ye-Aramid:
Ekwenziweni kwemicu ye-aramid (isib., i-Kevlar®), i-DMAc isebenza njengesisombululo se-polyamide polymerization, okwenza bona kwakhiwe izinto eziqinileko khulu ezisetjenziswa ema-bulletproof vest, ama-aerospace composites, kanye neentambo zebubulo. Ukwenza isibonelo, abosonkontileka bezokuvikela be-US bathembele ku-DMAc ukukhiqiza imicu ye-aramid enamandla wokudonsa adlula i-3,600 MPa.
Amafilimu we-Polyimide:
Isetjenziselwa ukukhiqiza amafilimu we-polyimide (PI) (isib., i-Kapton®), i-DMAc incibilikisa ama-precursors we-polyamic acid, okwenza bona kube nokulawula okuqondileko kobukhulu befilimu kanye nezakhiwo zokubona. Amafilimu la aqakathekile kuma-elekthronikhi atjhugulukako (isib., iinthombe ze-OLED, ama-PCB atjhugulukako) kanye nokuvikela amazinga womtjhiso aphezulu eenjinini zeenkoloyi.
I-spandex kanye nemicu yokwenziwa:
Ekukhiqizeni iindwangu (isib., iintjalo ze-Asia spandex), i-DMAc yenza kube lula ukuphotha imicu ye-polyurethane, ukuqinisekisa ububanzi obufanako nokuthamba kweendwangu ezisetjenziselwa izambatho zemidlalo kanye nezambatho zokugandeleleka kwezokwelapha.
2. Imithi nethekhnoloji yezinto eziphilako: Isisombululo nendlela yokuphendula
Ukuhlanganiswa kweendakamizwa:
I-DMAc isebenza njengesisombululo esihlukahlukeneko ekukhiqizweni kweenthako zezokwelapha ezisebenzako (i-API). Ikhono layo lokuncibilikisa kokubili amakhompawundi we-organic ne-inorganic kwenza bona ilungele ukuncibilika, ukujikeleza, kanye nokuphendula kwe-oksijini. Ukwenza isibonelo, isetjenziselwa ukwenza imitjhoga ye-antiretroviral (isib., iinqabo ze-HIV protease) eenkhungweni zemithi ze-Europe.
Isekelo lokwakheka:
Ekubunjweni okusetjenziswako (isib., amakhrimu, amajeli), i-DMAc ikhuphula ukungena kwemithi ye-lipophilic esikhumbeni, okwenza ngcono ukutholakala kwezinto eziphilako. Ibuye isetjenziswe eensombululweni ze-parenteral ngebanga lobuthi bayo obuphasi nokuhambisana nomzimba womuntu (LD₅₀ > 3,000 mg/kg emagundvwaneni).
Iinsetjenziswa ze-Biotech:
Ekukhiqizeni i-biopharmaceutical, i-DMAc isetjenziswa eenkambisweni zokuhlanza amaprotheyini, njenge-chromatography, ukwenza amaphrotheyini we-membrane ancibilike begodu enze ngcono ukusebenza kuhle kokuhlukaniswa.
3. Ibubulo le-Elekthronikhi ne-Semiconductor: Isisombululo esinembileko se-Microfabrication
Ukususwa kwe-photoresist:
Ekwenzeni ama-semiconductor, i-DMAc isetjenziswa eenkambisweni zokuhlanza ezithuthukisiweko ukususa iinsalela ze-photosist eziqinileko ezivela kuma-silicon wafers. I-solvency yayo ephezulu ye-epoxy - based photoresists yenza bona ibe yinto eqakathekileko ku-nanolithography (isib., i-EUV lithography yama-3nm chip nodes).
Ukukhiqizwa kwe-OLED ne-Display:
Ekukhiqizeni ama-organic light - emitting diodes (OLEDs), i-DMAc incibilikisa ama-semiconductors we-organic nama-dopants, okwenza bona kube nokufakwa kwefilimu encani efanako ngokusebenzisa ukugadangiswa kwe-inkjet nofana ukutjhatjhululwa okujikelezako. Abakhiqizi bemibukiso be-Korea basebenzisa i-DMAc ukufikelela ukunemba kwamaphikseli ukufikela esikalini sama-micrometer.
Ukufaka igezi nokutlola:
Isebenza njenge-co-solvent emabhathini wegolide nethusi, okwenza ngcono ukufana kwediphozithi kumathekhnoloji wokupakisha athuthukileko (isib., ama-3D IC, ukupakisha kwe-fan - out wafer level).
4. Ukusetjenziswa kwendwangu nesikhumba: Iinsombululo ezisimamako
Ukuphotha ifayibha yokwenziwa:
Ekukhiqizeni imicu ye-acrylic, i-DMAc ithatha indawo yeensombululo ezinobuthi (isib., i-dimethylformamide, i-DMF), inikela ngokuncibilika okufanako nomthelela omncani emvelweni. Iindawo zokugaya iindwangu ze-Europe zisebenzisa i-DMAc eenkambisweni ezivikela ibhoduluko eziqinisekiswe yi-OEKO - TEX® Standard 100.
Ukutjhugulula isikhumba:
Njengesikhundla sama-ejenti wesikhumba wesintu, i-DMAc ikhuphula ukungena kwama-tannins wemifino, ikhiqiza isikhumba esithambileko, esiphefumulako khulu sempahla yokunethezeka (isib., iinkhwama zesikhumba ze-Italy). Ukutjhuguluka kwayo okuphasi kwehlisa ukukhutjhwa kwe-VOC eendaweni zokutjhugulula.
5. Ukuhlanza nokukhipha amabubulo: ukusebenza kuhle nokuphepha
Ukususa amafutha ensimbini:
Ebubulweni le-aerospace nezeenkoloyi, i-DMAc isusa amafutha, amafutha, kanye neensalela ze-flux eengcenyeni ezinembileko (isib., ama-turbine blade, iingcenye zenjini). Izinga layo eliphezulu lokubilisa (166°C) liqinisekisa ukuhwamuka okuncani ngesikhathi sokuhlanza nge-ultrasound, ukwehlisa ukulahlekelwa kwesisombululo.
Ukukhutjhwa komkhiqizo wemvelo:
Isetjenziselwa ukukhipha ama-pigment wemvelo (isib., ama-carotenoids avela ku-algae) kanye nemithi evela eentjalweni, i-DMAc inikela ngokukhetha ukubhadela ngaphandle kokuphazamisa ukusebenza kwezinto eziphilako zamakhompawundi ahlosiweko.
