Daim ntawv thov ntawm Dimethylacetamide DMAC

Dimethylacetamide DMACyog ib qho tshuaj yaj dipolar aprotic siv rau ntau yam kev hloov pauv organic thiab kev siv hauv kev lag luam. Nws yog ib qho tshuaj yaj uas siv tau ntau yam vim nws lub ntsiab lus kub siab thiab kev ruaj khov zoo hauv thermal thiab tshuaj lom neeg.

1. Cov fibers acrylic
Dimethylacetamide DMACsiv ua cov kuab tshuaj hauv cov txheej txheem ntub dej rau kev tsim cov acrylic fibers.
2. Cov fibers Elasthane
Hauv kev tsim cov polyurethane-based elasthane fibers,Dimethylacetamide DMACyog cov kuab tshuaj uas xaiv los ntawm nws qhov ceev ntawm kev ua kom qhuav, txawm tias nws siv rau hauv cov txheej txheem ntub lossis qhuav.
3. Cov Tshuaj
Dimethylacetamide DMACsiv tau ob qho tib si ua cov kuab tshuaj thiab ua cov tshuaj reagent hauv kev tsim ntau yam tshuaj. Hauv kev tsim cov tshuaj x-ray tshiab,Dimethylacetamide DMACsiv ua cov kuab tshuaj. Cephalosporins, uas yog ib qho ntawm cov tshuaj tua kab mob tseem ceeb, ib feem yog tsim los ntawm cov derivatives ntawm 7-ADCA (7-aminodeacetoxy-cephalosporanic acid).Dimethylacetamide DMACyog siv rau hauv cov txheej txheem tsim khoom.
4. Ntau yam polymers
Dimethylacetamide DMACyog ib qho tshuaj yaj zoo rau cov polyimide resins, ob qho tib si hauv kev tsim cov txheej thiab zaj duab xis. Nws tseem yog cov tshuaj yaj zoo tagnrho rau kev tsim cov dialyser membranes, raws li polysulfones. Kev sib xyaw ntawm DMAC thiab lithium chloride yog ib qho tshuaj yaj zoo rau cov cellulose fibers hauv ntau daim ntawv thov.
