Gabatarwar samfur da fasaloli

N-hydroxymethylacrylamide foda ne mai farin lu'ulu'u. Yawan da ake buƙata shine 1.185 (23/4 ℃), kuma wurin narkewa shine 75 ℃. A cikin ruwan hydrophilic gabaɗaya ana iya narkar da shi, ga masu kitse acid esters, acrylic acid da methylacrylate, dumama kuma yana da isasshen narkewa, amma kusan ba ya narkewa a cikin ruwan hydrophobic kamar hydrocarbons, halogenated hydrocarbons. Ana iya amfani da shi azaman wakilin haɗin giciye, ana amfani da shi sosai a cikin resin fiber modified, rini na sarrafawa, manne filastik, mai daidaita ƙasa, da sauransu. Kwayoyin samfurin suna da haɗin biyu da aka haɗa tare da ƙungiyar carbonyl da ƙungiyar hydroxyl methyl mai amsawa. Monomer ne mai haɗin giciye wanda ake amfani da shi sosai don gyaran zare, sarrafa resin, manne, takarda, fata, wakilin maganin saman ƙarfe, kuma ana iya amfani da shi azaman gyaran ƙasa.

amfani

Kayan aiki ne da ake amfani da shi wajen kera resin thermosetting, shafa mai mai laushi na epoxy resin, shafa mai mai jure wa mai da kuma shafa mai bushewa. Ana amfani da emulsion ɗinsa don kammala zare, shafa masaka, fata da takarda. Haka kuma ana amfani da shi azaman manne ga itace, ƙarfe, da sauransu.
Ana amfani da shi azaman monomer mai haɗin giciye don emulsion na acrylic. Yawan manne mai laushi na acrylic emulsion wanda ke ɗauke da ƙungiyar carboxyl shine L% ~ 2% na jimlar nauyin monomer, idan ya wuce 3%, ɗanko na farko zai ragu sosai. Ga manne mai laushi ba tare da ƙungiyar carboxyl ba, yawan maganin gabaɗaya bai wuce 5% ba. Zafin amsawar haɗin giciye na MMAM kaɗai ya fi girma, gabaɗaya 120 ~ 170℃, ƙara mai haɓaka nau'in proton zai iya rage zafin haɗin giciye. Acrylic acid (AA) zai iya samar da hydrogen protons, da kuma copolymerization tare da acrylate, don haka MMAM don samar da wakili mai haɗin giciye tare da AA, adadin 3:2 ya fi kyau. HA mai haɗin giciye zai iya maye gurbin N-hydroxymethylacrylamide kuma bai ƙunshi formaldehyde ba.

B. Ana iya amfani da wannan samfurin, 25KG, jakunkuna
C. A adana a cikin akwati mai sanyi, bushe da iska a ciki. Ya kamata a rufe kwantena sosai bayan kowane amfani kafin amfani.
D. Ya kamata a rufe wannan samfurin sosai yayin jigilar kaya don hana haɗuwa da danshi, alkali mai ƙarfi da acid, ruwan sama da sauran ƙazanta.
