Premium Dimethylacetamide (DMAc): Solvent ea Polar e nang le Tshebetso e Phahameng bakeng sa Liindasteri tse Tsoetseng Pele
Masimo a Maholo a Kopo
1. Indasteri ea Polymer: Ho nolofalletsa Lisebelisoa tsa Tshebetso e Phahameng
DMAc ke lejwe la motheo tlhahisong ea li-polymer tse tsoetseng pele, haholo-holo tlhahisong ea likhoele le lifilimi tse matla haholo:
Likhoele tsa Aramid:
Ha ho etsoa likhoele tsa aramid (mohlala, Kevlar®), DMAc e sebetsa e le tharollo bakeng sa polymerization ea polyamide, e nolofalletsang ho etsoa ha thepa e matla haholo e sebelisoang lijeseng tse thibelang likulo, metsoako ea lifofane le liropo tsa indasteri. Mohlala, borakonteraka ba tšireletso ba US ba itšetlehile ka DMAc ho hlahisa likhoele tsa aramid tse nang le matla a ho thaepa a fetang 3,600 MPa.
Lifilimi tsa Polyimide:
Ha e sebelisoa tlhahisong ea lifilimi tsa polyimide (PI) (mohlala, Kapton®), DMAc e qhala li-precursor tsa polyamic acid, e leng se lumellang taolo e nepahetseng ea botenya ba filimi le thepa ea optical. Lifilimi tsena li bohlokoa haholo li-elektronikeng tse tenyetsehang (mohlala, lipontšo tsa OLED, li-PCB tse tenyetsehang) le ho thibela mocheso o phahameng lienjeneng tsa likoloi.
Likhoele tsa Spandex le tsa Maiketsetso:
Tlhahisong ea masela (mohlala, limela tsa spandex tsa Asia), DMac e thusa ho potoloha ha likhoele tsa polyurethane, e netefatsa bophara bo lekanang le ho tenyetseha ha masela a sebelisetsoang liaparo tsa lipapali le liaparo tsa khatello ea bongaka.
2. Meriana le Biotechnology: Mokgwa wa ho qhibilihisa le ho arabela
Tlhahiso ea Lithethefatsi:
DMac e sebetsa e le tharollo e feto-fetohang mefuteng e fapaneng ea meriana le tlhahiso ea metsoako e sebetsang ea meriana (API). Bokhoni ba eona ba ho qhala metsoako ea tlhaho le e sa pheleng bo etsa hore e be ntle bakeng sa ho kolobisa, ho potoloha ha metsi le ho etsa hore e be le phello ea oxidation. Mohlala, e sebelisoa ho kopanyeng meriana ea antiretroviral (mohlala, li-HIV protease inhibitors) litsing tsa meriana tsa Europe.
Tšehetso ea ho qapa:
Mefuteng ea litlolo (mohlala, litlolo, li-gel), DMac e ntlafatsa ho kenella ha meriana ea lipophilic letlalong, e ntlafatsa ho fumaneha ha eona. E boetse e sebelisoa litharollong tsa parenteral ka lebaka la chefo ea eona e tlase le ho lumellana ha eona le 'mele oa motho (LD₅₀ > 3,000 mg/kg ho likhoto).
Likopo tsa Biotech:
Tlhahisong ea meriana ea biopharmaceutical, DMac e sebelisoa lits'ebetsong tsa tlhoekiso ea protheine, joalo ka chromatography, ho qhibilihisa liprotheine tsa lera le ho ntlafatsa katleho ea karohano.
3. Indasteri ea Elektroniki le Semiconductor: Sethapo se Nepahetseng bakeng sa Microfabrication
Ho Tlosa Photoresist:
Tlhahisong ea semiconductor, DMac e sebelisoa lits'ebetsong tse tsoetseng pele tsa ho hloekisa ho tlosa masala a manganga a ho hanyetsa photoresis ho tsoa ho li-wafer tsa silicon. Ho ba le solvent e phahameng bakeng sa li-photoresis tse thehiloeng ho epoxy ho etsa hore e be ea bohlokoa ho nanolithography (mohlala, lithography ea EUV bakeng sa li-chip node tsa 3nm).
Tlhahiso ea OLED le Pontšo:
Tlhahisong ea li-diode tse ntšang khanya ea tlhaho (li-OLED), DMac e qhala li-semiconductor le li-dopants tsa tlhaho, e leng se nolofalletsang ho kenngoa ha filimi ka mokhoa o ts'oanang ka khatiso ea inkjet kapa ho penta ka spin. Bahlahisi ba ponts'o ea Korea ba sebelisa DMac ho fihlela ho nepahala ha pixel ho fihlela sekaleng sa micrometer.
Ho polata ka motlakase le ho fata:
E sebetsa e le motsoako o kopanyang dibateng tsa ho betla ka motlakase bakeng sa kgauta le koporo, e ntlafatsa ho tshwana ha depositi mahlaleng a tswetseng pele a ho paka (mohlala, di-IC tsa 3D, ho paka ka wafer e sa keneng ka fene).
4. Ts'ebetso ea Masela le Letlalo: Litharollo tse Tšoarellang
Ho Ohla ha Faeba ya Maiketsetso:
Tlhahisong ea likhoele tsa acrylic, DMAc e nkela litharollo tse chefo tse ngata sebaka (mohlala, dimethylformamide, DMF), e fanang ka solvency e tšoanang le tšusumetso e tlase ea tikoloho. Lifeme tsa masela tsa Europe li sebelisa DMAc lits'ebetsong tse mosa tikolohong tse netefalitsoeng ke OEKO - TEX® Standard 100.
Ho Letlalo le Sulang:
E le sebaka sa di-agent tsa setso tsa ho tjhesa letlalo, DMac e ntlafatsa ho kenella ha di-tannins tsa meroho, e hlahisa letlalo le bonolo, le phefumolohang habonolo bakeng sa thepa ya mabothobotho (mohlala, mekotla ya letlalo ya Italy). Ho fetofetoha ha yona ho tlase ho fokotsa ho ntsha ha VOC dibakeng tsa ho tjhesa letlalo.
5. Ho Hloekisa le ho Ntša Liindasteri: Bokgoni le Polokeho
Ho Tlosa Mafura ka Tšepe:
Liindastering tsa lifofane le tsa likoloi, DMac e tlosa masala a oli, mafura le flux ho tsoa likarolong tse nepahetseng (mohlala, mahare a turbine, likarolo tsa enjene). Sebaka sa eona se phahameng sa ho belisa (166°C) se netefatsa mouoane o fokolang nakong ea ho hloekisa ka ultrasound, e leng se fokotsang tahlehelo ea solvent.
Ho Ntša Sehlahisoa sa Tlhaho:
E sebelisoa ho ntšeng mebala ea tlhaho (mohlala, li-carotenoid tse tsoang boleleng) le meriana e tsoang linthong tsa limela, DMAc e fana ka tharollo e ikhethileng ntle le ho beha kotsing ea bioactivity ea metsoako e reriloeng.
