Te whakataki me ngā āhuatanga o te hua
He paura tioata mā te N-hydroxymethylacrylamide. Ko te kiato whanaunga ko 1.185 (23/4 ℃), ā, ko te ira rewa ko 75 ℃. I roto i te whakarewa hydrophilic whānui, ka taea hoki te whakarewa i te whakarewa hydrophilic, mō ngā esters waikawa ngako, te waikawa acrylic me te methylacrylate, he nui te wairewa i te whakamahana, engari tata kore e wairewa i roto i ngā whakarewa hydrophobic pērā i ngā warowaihā, ngā warowaihā halogenated. Ka taea te whakamahi hei kaihoko hononga-whiti, he whānui te whakamahi i roto i te kapia whakarerekētia muka, te tae tukatuka, te here kirihou, te whakaū oneone, me ētahi atu. He hononga takirua te ngota o te hua e hono ana ki te rōpū carbonyl me te rōpū hydroxyl methyl tauhohe. He monomer hononga-whiti e whakamahia whānuitia ana mō te whakarerekētanga muka, te tukatuka kapia, ngā piripiri, te pepa, te hiako, te kaihoko maimoatanga mata whakarewa, ā, ka taea hoki te whakamahi hei whakatikatika oneone.
whakamahi
He rauemi mata tēnei mō te hanga i te kapia whakamahana, te paninga kapia epoxy whakamaroke mārama, te paninga ātete hinu me te paninga whakamaroke. Ka whakamahia tōna ranunga copolymerization mō te whakaoti muka, te paninga papanga, te hiako me te pepa. Ka whakamahia hoki hei piripiri mō te rakau, te whakarewa, me ētahi atu.
Whakamahia hei monomer whakawhiti-hono mō te whakamomona kiriaku. Ko te horopeta o te piripiri kiriaku whakamomona pēhanga kei roto te rōpū carboxyl he L % ~ 2% o te papatipu monomer katoa, ki te nui ake i te 3%, ka tino heke te matotoru tuatahi. Mō te piripiri whakamomona kāore he rōpū carboxyl, ko te horopeta whānui kāore e neke atu i te 5%. He teitei ake te pāmahana tauhohenga whakawhiti MMAM anake, ko te tikanga 120 ~ 170℃, mā te tāpiri i te whakakorikori momo-porotini ka taea te whakaiti i te pāmahana whakawhiti. Ka taea e te waikawa kiriaku (AA) te whakarato i ngā porotini hauwai, me te copolymerization me te acrylate, nō reira ko te MMAM hei hanga i te kaihoko whakawhiti hiato me te AA, he pai ake te nui o te 3:2. Ka taea e te hononga-whakamomo HA te whakakapi i te N-hydroxymethylacrylamide, ā, kāore he formaldehyde.
mōkihi me te kawe
B. Ka taea te whakamahi i tēnei hua, 25KG, PĒKE
C. Penapenahia kia hiri ki roto i te wāhi hauhautanga, maroke, me te hauhautanga. Me hiri rawa ngā ipu i muri i ia whakamahinga i mua i te whakamahinga.
D. Me hiri pai tēnei hua i te wā e kawe ana kia kore ai e uru te makuku, te kawakore me te waikawa kaha, te ua me ētahi atu poke.
