Fa'aaogāina o le Dimethylacetamide DMAC

Dimethylacetamide DMACo se vaila'au fa'aprotic dipolar e fa'aaogaina mo le tele o fa'agasologa fa'alenatura ma fa'aoga fa'apisinisi. O se vaila'au fa'asolo e tele ona aoga ona o lona maualuga o le pupuna ma le lelei o le mautu i le vevela ma vaila'au.

1. Alava acrylic
Dimethylacetamide DMACe faʻaaogaina o se vailaʻau faʻamaʻi i faiga milo susu mo le gaosiga o alava acrylic.
2. Alava elasthane
I le gaosiga o alava elasthane e faʻavae i le polyurethane,Dimethylacetamide DMACo le vaila'au fa'amama e filifilia ona o lona saoasaoa o le fa'amamago, pe fa'aaogaina i faiga vili susu pe mago.
3. Fale Talavai
Dimethylacetamide DMACe mafai ona fa'aaogaina e fai ma vaila'au fa'amama ma se vaila'au fa'aola i le gaosiga o vaila'au eseese. I le gaosiga o mea fou e fa'aalia ai le eseesega o le x-ray,Dimethylacetamide DMACe fa'aaogaina o se vaila'au fa'amama. O Cephalosporins, o se tasi o vasega ta'imua o vaila'au fa'ama'i, e gaosia fa'atasi mai mea e maua mai i le 7-ADCA (7-aminodeacetoxy-cephalosporanic acid).Dimethylacetamide DMACe faʻaaogaina i le faagasologa o le gaosiga.
4. Polymers eseese
Dimethylacetamide DMACo se vaifofo lelei mo resins polyimide, i le gaosiga o ufiufi ma ata tifaga. O le vaifofo sili foi lea mo le gaosiga o membranes dialyser, e faʻavae i luga o polysulfones. O le faʻafefiloi o le DMAC ma le lithium chloride o se vaifofo aoga mo alava cellulose i le tele o faʻaoga.
