Shaqayn

DMAC waxaa inta badan loo adeegsadaa sidii xalka loogu talagalay fiber-ka synthetic (acrylonitrile) iyo polyuthane polyamile iyo polyamide polyamide, waxaana sidoo kale loo istcimaalaa sicirka murqaha ah ee xalka ah, oo si ballaaran loogu adeegsado filimada polymer, jaakadaha iyo dawooyinka, iwm. Waqtigan xaadirka ah, waxaa si weyn loogu isticmaalaa daawada iyo sunta cayayaanka si uu u istaago antibiyootig iyo sunta cayayaanka lagu buufiyo. Waxaa sidoo kale loo isticmaali karaa in loo isticmaalo falcelinta falcelinta, dareeraha korantada elektrolytic, scavent-ka rinjiga, iyo waxyaabaha kala duwan ee crystallone-ka kala duwan iyo isku-dhafan.

Sifo

N, n-Dimethylacometamide, oo sidoo kale loo yaqaan 'attytytimethylamine', actytimethylamine, ama DMAC ee gaagaaban, waa xallin ba'an u eg ubax yar, silsilado xoog leh, iyo waxyaabo badan oo ka mid ah walxaha adag. Waa mid si daran u dhici kara biyaha, xeryahooda udgoon, esters, ketones, aalkolo, benzene iyo chlorofent, oo ay dhaqaajin karaan moleekulada isku-darka, sidaa darteed waxaa si weyn loo isticmaalaa sidii solvent iyo casharka. Marka laga hadlayo xalka, sida xalka leh dhibicda sare, barta sare, deganaanshaha kuleylka iyo xasilloonida dabiiciga ah, waxaa loo isticmaali karaa polyacrylonit-ka, veylyl-ka vinyl-ka iyo waxyaabaha kale ee loo yaqaan 'convolacylic'. Marka laga hadlayo kadhiga, waxaa loo isticmaali karaa habka kuleylka urea in ay soo saarto cudurka 'ceyra acid', falcelinta 'cluetyl', oo falcelinta birta ee alkyl alkyne, iyo falcelinta aalkolada iyo ceyrinta dabiiciga ah ee loo yaqaan 'organide' iyo ceyrate-ka si loo soo saaro isbahaysi. N, n-Dimethyylacotamide sidoo kale waxaa loo isticmaali karaa sidii solvency clortrolysis soltrolysis iyo toblepler, rinjiyeynta rinjiga, squesis-ka dabiiciga ah ee sheyga ceeriin, sunta cayayaanka iyo dawooyinka ceeriin. Xadhiga muxaadaroodka ee aan la soo saari karin ee loogu talagalay kala-goynta styrene ee jajabka C8, iwm.
