Yuav Dimethylacetamide DMAC CAS 127-19-5
N,N-Dimethylacetamide DMAcyog ib qho hnyav hnyav nrog lub zog daws teeb meem rau siab molecular - hnyav polymers thiab hluavtaws resins. DMAc yog siv los ua cov tshuaj tiv thaiv hnyav rau kev tsim cov acryl thiab polyamide fibers. DMAc hnyav kuj tseem siv rau kev tsim cov tshuaj agrochemical, dyes thiab tshuaj.

DMAC hnyav Cia thiab Kev Nyab Xeeb
Cia:Khaws rau hauv cov thawv kaw ntom ntom (stainless steel lossis HDPE) hauv qhov txias, qhuav, zoo - qhov cua qhov chaw, kom deb ntawm qhov hluav taws kub.
Kev nyab xeeb:Cov nplaim taws heev (63℃flash point). Nws yog tshuaj lom thiab tuaj yeem ua rau tawv nqaij / qhov muag khaus; siv nyob rau hauv lub qhov dej - qhov cua qhov chaw nrog cov khoom tiv thaiv tsim nyog (cov hnab looj tes nitrile, tsom iav).
