Kushandiswa kweDimethylacetamide DMAC

Dimethylacetamide DMACi solvent ye dipolar aprotic inoshandiswa pakuita zvinhu zvakasiyana-siyana uye mumaindasitiri. I solvent inoshandiswa zvakasiyana-siyana nekuda kwekufashaira kwayo zvakanyanya uye kugara zvakanaka kwekupisa nemakemikari.

1. Fiber dzeAcrylic
Dimethylacetamide DMACinoshandiswa se solvent mukuita kwekunyorova kwemvura pakugadzira ma acrylic fibers.
2. Fiber dzeElasthane
Mukugadzirwa kwemafiber elasthane akavakirwa pa polyurethane,Dimethylacetamide DMACndiyo solvent inosarudzwa tichifunga nezvekumhanya kwayo kwekubuda kwemvura, kungave kuchishandiswa mukutenderera kwakanyorova kana kwakaoma.
3. Mishonga
Dimethylacetamide DMACinogona kushandiswa semushonga wekugadzirisa makemikari uye semushonga wekugadzirisa makemikari mukugadzirwa kwemishonga yakasiyana-siyana. Mukugadzirwa kwemifananidzo mitsva yeX-ray contrast,Dimethylacetamide DMACinoshandiswa semushonga unonyungudutsa. Cephalosporins, dziri pakati pemhando dzinotungamira dzemishonga inorwisa mabhakitiriya, dzinogadzirwa zvishoma kubva mu7-ADCA (7-aminodeacetoxy-cephalosporanic acid).Dimethylacetamide DMACinoshandiswa mukugadzirwa kwezvinhu.
4. Mapolima akasiyana-siyana
Dimethylacetamide DMACinonyungudutsa zvakanaka pa polyimide resins, mukugadzira coating uye firimu. Ndiyo inonyungudutsawo yakakodzera pakugadzira dialyser membranes, zvichibva pa polysulfones. Musanganiswa weDMAC ne lithium chloride inonyungudutsa inobatsira pa cellulose fibers mumabasa akasiyana-siyana.
