Dimethylacetamide ya Maemo a a Kwa Godimo (DMAc): Setlhaolosi sa Polar sa Tiragatso e e Kwa Godimo sa Diintaseteri tse di Gatetseng Pele

Dikarolo tse dikgolo tsa Tiriso

1. Intaseteri ya Dipolymer: Go Kgontsha Didirisiwa tsa Tiragatso e e Kwa Godimo
DMAc ke motheo wa go tlhagisa dipolymer tsa maemo a a kwa godimo, segolobogolo mo go kopanyeng ditlhale le difilimi tse di nonofileng thata:
Ditlhale tsa Aramid:
Mo go direng ditlhale tsa aramid (sekao, Kevlar®), DMAc e dira jaaka setlhaolosi sa polymerization ya polyamide, e e kgontshang go tlhama didirisiwa tse di maatla thata tse di dirisiwang mo diveste tse di thibelang dikolo, mo dikhomphositeng tsa difofane, le mo dithapong tsa madirelo. Ka sekai, borakonteraka ba tshireletso ba kwa Amerika ba ikaegile ka DMAc go tlhagisa ditlhale tsa aramid tse di nang le maatla a go gagamala a a fetang 3 600 MPa.
Difilimi tsa Polyimide:
E dirisiwa mo tlhagisong ya difilimi tsa polyimide (PI) (sekao, Kapton®), DMAc e phatlalatsa di-precursor tsa polyamic acid, e letla taolo e e tlhomameng ya botelele jwa filimi le dithoto tsa matlho. Difilimi tseno di botlhokwa thata mo dilong tsa ileketeroniki tse di fetofetogang (sekao, dipontsho tsa OLED, di-PCB tse di fetofetogang) le go thibela mogote o o kwa godimo mo dikoloing tsa dikoloi.
Ditlhale tsa Spandex le tsa Maitirelo:
Mo tlhagisong ya masela (sekao, dimela tsa spandex tsa Asia), DMAc e nolofatsa go dikologa ga ditlhale tsa polyurethane, go netefatsa gore molagare o o tshwanang le go elasticity mo matseleng a a dirisediwang diaparo tsa metshameko le diaparo tsa kgatelelo ya kalafi.

2. Dikhemisi le Baeothekenoloji: Setlhaolosi le Sedirisiwa sa Tsibogo
Tshwaetso ya Diokobatsi:
DMAc e sebetsa e le solvent e fapaneng ka meriana intermediates le mafolofolo meriana motsoako (API) tlhahiso. Bokgoni jwa yone jwa go phatlalatsa metswako ya ditshedi le e e sa tsheleng bo dira gore e nne e e siametseng diphetogo tsa go tlhotlhorega, go dira dipopego tsa ditshedi le go dira gore e nne le oksijene. Ka sekai, e dirisiwa mo tshwaraganong ya melemo ya antiretroviral (sekao, dithibela-protease ya HIV) mo ditheong tsa melemo tsa Yuropa.
Tshegetso ya go Tlhama:
Mo ditlhamong tsa setlhogo (sekao, ditlolo, di-gel), DMAc e tokafatsa go tsenelela ga melemo ya lipophilic ka letlalo, e tokafatsa go nna teng ga ditshedi. E dirisiwa gape mo ditharabololo tsa parenteral ka ntlha ya botlhole jwa yona jo bo kwa tlase le go tsamaelana le fisioloji ya motho (LD50 > 3,000 mg/kg mo dipeba).
Ditiriso tsa Baeothekenoloji:
Mo tlhagisong ya dikhemisi tsa ditshedi, DMAc e dirisiwa mo dithulaganyong tsa go phepafatsa diporoteine, jaaka chromatography, go tswakanya diporoteine ​​tsa lera le go tokafatsa bokgoni jwa go kgaoganya.

3. Intaseteri ya Dieleketeroniki le Di-Semiconductor: Setlhaolosi se se Nepagetseng sa go Dira Dilo Tse Dinnye
Go Tlosiwa ga Sethibela-Lesedi:
Mo go tlhameng di-semiconductor, DMAc e dirisiwa mo dithulaganyong tsa go phepafatsa tse di tsweletseng pele go tlosa masalela a a tlhogoethata a photoresist mo di-wafer tsa silicon. Go kgona go rarabolola ga yone go go kwa godimo ga di-photoresist tse di theilweng mo epoxy go dira gore e nne botlhokwa thata mo nanolithokerafing (sekao, lithokerafi ya EUV ya dinoutu tsa ditšhipi tsa 3nm).
OLED le Dipontsho Tlhagiso:
Mo tlhagisong ya di-diode tse di ntshang lesedi la ditshedi (OLEDs), DMAc e phatlalatsa di-semiconductor le di-dopant tsa ditshedi, e kgontsha go tsenngwa ga difilimi tse di tshesane tse di tshwanang ka go gatisa ka enke kgotsa ka go di apesa ka spin. Batlhagisi ba dipontsho ba Korea ba dirisa DMAc go fitlhelela go nepagala ga dipiksele go fitlha kwa dikale tsa micrometer.
Go tshasa ka motlakase le go gatisa:
E dira jaaka setlhaolosi-mmogo mo ditlhapeng tsa electroplating tsa gauta le kopore, go tokafatsa go tshwana ga dipeeletso mo dithekenolojing tse di tsweletseng tsa go phuthela (sekao, di-IC tsa 3D, go phuthela ga maemo a wafer ya fan - out).

4. Go Dira Matsela le Letlalo: Ditharabololo tse di Tswelelang Pele
Go Dikolosa Tlhale ya Maitirelo:
Mo tlhagisong ya ditlhale tsa acrylic, DMAc e emisetsa ditlhaolosi tse dintsi tse di botlhole (sekao, dimethylformamide, DMF), e neelana ka tlhaolosi e e bapisiwang ka tshusumetso e e kwa tlase ya tikologo. Ditshilo tsa matsela tsa Yuropa di dirisa DMAc mo dithulaganyong tse di sa senyeng tikologo tse di netefaditsweng ke OEKO - TEX® Standard 100.
Go suga letlalo:
Jaaka sebaka sa diokobatsi tsa setso tsa go ntsha letlalo, DMAc e tokafatsa go tsenelela ga di-tannin tsa merogo, e tlhagisa letlalo le le boleta, le le hemang thata la dithoto tsa manobonobo (sekao, dikgetsi tsa letlalo tsa Italy). Go fetogafetoga ga yona go go kwa tlase go fokotsa mesi ya VOC mo mafelong a go tlhotlhora letlalo.

5. Go Phepafatsa le go Ntsha mo Diintasetering: Bokgoni le Pabalesego
Go ntsha mafura mo tshiping:
Mo madirelong a aerospace le a dikoloi, DMAc e tlosa oli, kirisi, le masalela a flux mo dikarolong tsa nepo (sekao, di-blade tsa turbine, dikarolo tsa enjene). Ntlha ya yona e e kwa godimo ya go bela (166°C) e netefatsa mowafatso e nnye ka nako ya go phepafatsa ka ultrasonic, go fokotsa tatlhegelo ya solvent.
Go Ntshiwa ga Dikumo tsa Tlhago:
E dirisiwa mo go ntsheng ga dipigmente tsa tlhago (sekao, di-carotenoid go tswa mo algae) le melemo go tswa mo dilong tsa dimela, DMAc e neelana ka go tlhopha go rarabolola ntle le go senya bioactivity ya metswako e e ikaeletsweng.

E ka dirisiwa gape le go tsamaisana le dithulaganyo tsa madirelo tse di tswetsweng, tse di tsamaelanang le maikaelelo a Leano la Tiro la Ikonomi ya Sediko la EU.
Polokego:
E phuthetswe ka meropa ya tshepe e sa hloekang kapa ditankeng tsa ISO, ka ho ikamahanya ka botlalo le MSDS le ho tshwaya ha GHS bakeng sa dipalangwa tse bolokehileng (UN 2265, Sehlopha sa 3).

Ke Eng fa re Tlhopha Dimethylacetamide ya Rona?

E ka tswa o tlhama dipolymer tsa kokomana e e latelang tsa difofane, go dira di-semiconductor tsa maemo a a kwa godimo, kgotsa go tlhama melemo e e itlhametsweng, DMAc ya rona e naya bokgoni jo bo sa tshwaneng le jwa go rarabolola le go ikanyega. Ka tshehetso ya botekgeniki ya lefatshe le ketane ya phepelo e ntlafaditsweng bakeng sa thomelo e potlakileng, re netefatsa hore ditshebetso tsa hao di rua molemo ho tshebetso le ho tswella ha solvent ena e fapaneng.

Lotlolola bokgoni ba thepa e tsoetseng pele le Premium Dimethylacetamide-moo ho nepahala ho kopanang le tshebetso indastering e nngwe le e nngwe.
