N,N{0}}Dimethylformamide ntom ntom
Qhov ceev ntawm ntshiab dimethylformamide (DMF) yog 0.944 g / cm³ (los yog 7.88 lb / gal) ntawm 25℃(77℃F). DMF yog me ntsis ntom dua dej.
N,N{0}}Dimethylformamide flash point
DMF muaj qhov kaw - khob qhov taw tes ntawm 58℃(136.4℃F). Qhov no faib DMF ua cov kua Flammable (Qeb 3) raws li GHS. Nws tso cai cia kom deb ntawm tshav kub, sparks, thiab qhib nplaim taws, thiab yuav tsum tau grounding thaum lub sij hawm hloov mus los tiv thaiv kom txhob muaj static paug.
N,N{0}}Dimethylformamide melting point
Lub melting point (kwv yees) ntawm DMF yog -61℃(-77.8℃F). Qhov no yog qhov kub ntawm cov kua DMF hloov mus rau hauv cov xim tsis muaj xim crystalline.
dMF chemical tag nrho daim ntawv
Lub Npe Tshuaj Txhuam Hniav: N, N-Dimethylformamide
Formamide: Cov niam txiv sib xyaw yog formamide (HCONH₂), muab los ntawm formic acid.
N,N-Dimethyl: Ob lub hydrogen atoms ntawm nitrogen (amide nitrogen) yog txhua tus hloov los ntawm ib pawg methyl (-CH₃).
DMF Structure: HCON(CH₃)₂ lossis (CH₃)₂NCHO.
Kev siv Solvent Dimethylformamide
Cov txheej txheem tiv thaiv
Vim nws cov solubility siab, dimethylformamide (DMF) tso cai rau cov ntsiab lus resin ntau dua hauv cov kev daws teeb meem thiab tsim cov txheej tuab. Vim nws qhov kub kub nruab nrab, DMF feem ntau siv hauv ci - hom txheej.
Zaj duab xis
DMF yog zoo tagnrho rau casting PVC films. Nws tuaj yeem sib xyaw nrog lwm cov kuab tshuaj kom meej meej tswj cov txheej txheem casting, ua tiav pob tshab, granular, lossis txiv kab ntxwv tev textured nto los.
Polymer Zaj duab xis
CAS 68-12-2 DMF thiab nws cov derivative dimethylacetamide (DMAC) yog dav siv nyob rau hauv kev tsim ntawm ntau yam ntaub ntawv zaj duab xis vim lawv cov organic zog, zoo heev solubility, thiab synergistic los nrog lwm cov kuab tshuaj.
Printing Inks
Raws li kev sib koom ua ke- cov kuab tshuaj, DMF lub siab solubility tso cai rau kev siv cov ntaub ntawv tsis zoo soluble thiab txhim kho cov number case adhesion ntawm PVC films.
Kev kho ntawm DMF Chemical
- Siv cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab ua pa kom zoo thaum tuav.
- Tsis txhob ncua ntev ntawm daim tawv nqaij thiab nqus pa ntawm vapors.
- Siv nyob rau hauv ib qho chaw zoo - qhov cua qhov cua los yog nrog cov fume extraction systems.
