Gabatarwar samfur da fasali

N-hydroxymethylacrylamide shine farin crystalline foda.Matsakaicin dangi shine 1.185 (23/4 ℃), kuma wurin narkewa shine 75 ℃.A general hydrophilic sauran ƙarfi kuma za a iya narkar da, ga m acid esters, acrylic acid da methylacrylate, dumama kuma yana da babba solubility, amma kusan insoluble a hydrophobic kaushi kamar hydrocarbons, halogenated hydrocarbons.Za a iya amfani da a matsayin giciye-linking wakili, yadu amfani a fiber modified guduro, sarrafa rini, filastik daure, ƙasa stabilizer, da dai sauransu A kwayoyin na samfurin yana da biyu bond conjugated tare da carbonyl kungiyar da reactive hydroxyl methyl kungiyar.Yana da monomer mai haɗin giciye da aka yi amfani da shi don gyaran fiber, sarrafa guduro, adhesives, takarda, fata, wakilin jiyya na ƙarfe, kuma ana iya amfani dashi azaman gyaran ƙasa.

amfani

Yana da wani albarkatun kasa na yi na thermosetting guduro, haske curing epoxy guduro shafi, mai resistant shafi da bushewa shafi.Its copolymerization emulsion da ake amfani da fiber karewa, masana'anta, fata da takarda shafi.Hakanan ana amfani da ita azaman manne don itace, ƙarfe, da sauransu.
Ana amfani dashi azaman monomer mai haɗin giciye don emulsion acrylic.Matsakaicin acrylic emulsion matsa lamba m m dauke da carboxyl kungiyar ne L% ~ 2% na jimlar monomer taro, idan fiye da 3%, farkon danko za a rage sosai.Don mannen emulsion ba tare da ƙungiyar carboxyl ba, babban adadin bai wuce 5%.MMAM crosslinking dauki zafin jiki shi kadai ya fi girma, gabaɗaya 120 ~ 170 ℃, ƙara nau'in proton mai kara kuzari na iya rage zafin ƙetare.Acrylic acid (AA) na iya samar da protons na hydrogen, da copolymerization tare da acrylate, don haka MMAM don samar da wakili mai haɗin gwiwa tare da AA, adadin 3: 2 ya fi kyau.Mai haɗin giciye HA na iya maye gurbin N-hydroxymethylacrylamide kuma baya ƙunshi formaldehyde.
