A zafin ɗaki, yana da farin foda ko lu'ulu'u mai laushi, yana narkewa a cikin ruwa da kuma sinadarai masu narkewa kamar formaldehyde, ethanol, acetone, tetrahydrofuran, ethyl acetate, acrylonitrile, styrene, da sauransu. Samfurin yana da sauƙin samar da polymer ta hanyar haɗakar sinadarai tare da monomer daban-daban kuma yana samun ƙarfi wajen sha ruwa, amma ba ya narkewa a cikin ethane, petroleum ether.
DAAM tana da ƙungiyoyi biyu masu amsawa, wato N - amides da ketone, yana da matuƙar sauƙi a haɗa shi da sauran monomer ɗin vinyl, don haka gabatar da kaddarorin sinadarai na ketone carbonyl na iya haifar da polymer zuwa haɗin gwiwa da amsawar graft, wanda zai iya shirya manne daban-daban, mai kauri, wakilin ƙarfafa takarda, wakilin haɗin gwiwa, da sauransu.
An yi amfani da shi sosai a fannoni kamar su shafa, manne, masana'antar sinadarai ta yau da kullun, wakilin warkar da epoxy resin, ƙarin resin mai canza launi, kayan taimakon yadi, kula da lafiya, da sauransu.
1. Maganin kula da gashi:
Wani muhimmin siffa ta DAAM ita ce homopolymer ko copolymer ɗinsa ba ya narkewa a cikin ruwa, amma yawan shan ruwansu zai iya kaiwa kashi 20% ~ 30% na nauyinsa, idan danshi na muhalli bai kai kashi 60% ba, har ma suna iya fitar da danshi, to ana iya samar da feshin gashi ta hanyar irin wannan siffa.
2. Resin mai sauƙin ɗaukar hoto:
Resin mai sauƙin ɗaukar hoto wanda homopolymer mai ƙarfi, mai tauri, mai juriya ga acid da alkaline ke samarwa yana da saurin ɗaukar hoto mai yawa na resin, ɓangaren da ba ya shafa yana da sauƙin cirewa bayan an fallasa shi, don haka yana samun tsari mai kyau na takarda tare da ƙarfi mai kyau da juriya ga ruwa.
Wani muhimmin amfani da DAAM shine cewa yana iya maye gurbin gelatin kaɗan, wanda ake amfani da shi don ɗaukar hoto mai ƙarfi kuma yana da wahalar maye gurbinsa da wasu samfuran da suka dace. Gelatin ya daɗe yana cikin ƙarancin wadatar ɗaukar hoto mai kyau, ana sa ran tan 2500 na gelatin don kayan da ke da saurin ɗaukar hoto, yayin da samar da gelatin na ɗaukar hoto na gida ya kai ɗaruruwan tan kawai a halin yanzu.
3. Ana amfani da shi don shirya buga rubutun filastik
4. Ana amfani da shi don mannewa:
Ana amfani da shi azaman mai haɓaka manne da ingantawa ga mahaɗan zare, siminti, gilashi, aluminum da PVC, a halin yanzu ana iya matse shi don samar da manne masu saurin matsi, kuma ana iya amfani da shi azaman manne masu saurin zafi don takarda, yadi da fim ɗin filastik tare da alloy polymer.
5. Aikace-aikacen a wasu fannoni:
