Kugwiritsa ntchito Dimethylacetamide DMAC

Dimethylacetamide DMACNdi solute ya dipolar aprotic yomwe imagwiritsidwa ntchito pazinthu zambiri zachilengedwe komanso ntchito zamafakitale. Ndi solute yosinthasintha chifukwa cha kutentha kwake kwambiri komanso kukhazikika bwino kwa kutentha ndi mankhwala.

1. Ulusi wa acrylic
Dimethylacetamide DMACimagwiritsidwa ntchito ngati chosungunulira mu njira zonyowa zopangira ulusi wa acrylic.
2. Ulusi wa Elasthane
Pakupanga ulusi wa elasthane wopangidwa ndi polyurethane,Dimethylacetamide DMACndi chinthu chosungunulira chomwe chimasankhidwa poganizira liwiro lake lotha kusungunuka, kaya chimagwiritsidwa ntchito popota monyowa kapena mouma.
3. Mankhwala
Dimethylacetamide DMACingagwiritsidwe ntchito ngati chosungunulira komanso ngati chothandizira popanga mankhwala osiyanasiyana. Pakupanga zinthu zatsopano zosiyanitsa ma x-ray,Dimethylacetamide DMACamagwiritsidwa ntchito ngati chosungunulira. Cephalosporins, zomwe zili m'gulu la magulu akuluakulu a maantibayotiki, zimapangidwa pang'ono kuchokera ku 7-ADCA (7-aminodeacetoxy-cephalosporanic acid).Dimethylacetamide DMACimagwiritsidwa ntchito popanga zinthu.
4. Ma polima osiyanasiyana
Dimethylacetamide DMACndi chosungunulira chabwino cha ma polyimide resins, popangira zokutira ndi kupanga filimu. Ndi chosungunulira chabwino kwambiri chopangira ma dialyser membranes, chochokera ku polysulfones. Chisakanizo cha DMAC ndi lithiamu chloride ndi chosungunulira chothandiza cha ulusi wa cellulose m'njira zosiyanasiyana.
