Dimethylformamide (DMF) Solvent rau Industrial siv
N,N-Dimethylformamide yog cov kuab tshuaj tshwj xeeb. Nws yog siv los ua cov kuab tshuaj rau polyurethane, polyacrylonitrile thiab polyvinyl chloride, nrog rau kev rho tawm thiab ua raw khoom rau cov tshuaj thiab tshuaj.
Dimethyl Formamide DMF kuj tseem siv rau hauv kev tsim cov yeeb yaj kiab yas thiab ua cov xim stripper.
Hauv kev lag luam petrochemical, nws tuaj yeem siv los ua cov roj absorber los cais thiab ua kom cov pa roj.
Hauv cov tshuaj tiv thaiv ntuj, N, N-dimethylformamide tau dav siv tsis yog tsuas yog ua cov kuab tshuaj rau cov tshuaj tiv thaiv xwb, tab sis kuj yog ib qho tseem ceeb nruab nrab ntawm ntuj tsim.
Hauv kev lag luam tshuaj, DMF hnyav tuaj yeem siv los tsim ciprofloxacin.
N,N-Dimethylformamide Cov Ntaub Ntawv Kev Nyab Xeeb
1. Toxicity: DMF yog tshuaj lom rau tib neeg. luv-lub sij hawm los yog ntev- lub sij hawm raug yuav ua rau lub cev ua pa, siab, thiab ob lub raum. Tsis tas li ntawd, DMF muaj peev xwm nqus tau los ntawm daim tawv nqaij. Yog li ntawd, yuav tsum tau saib xyuas kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus nws cov vapors.
2. Flammability: DMF CAS 68-12-2 yog flammable thiab yuav ignited. Thaum raug hluav taws kub los yog kub kub, nws ua rau cov pa nitrogen oxide pa phem thiab carbon dioxide.
3. Kev cuam tshuam ib puag ncig: DMF kuj ua rau muaj kev phom sij ib puag ncig. Nws tuaj yeem ua rau cov kab mob hauv dej los yog av. Yog li ntawd, yuav tsum tau siv cov kev ntsuas tsim nyog thaum siv lossis pov tseg DMF los tiv thaiv nws nkag mus rau hauv dej lossis av.
