Fa'atomuaga oloa ma foliga

N-hydroxymethylacrylamide o se paʻepaʻe tioata paʻepaʻe.Ole maualuga ole va'aiga ole 1.185(23/4 ℃), ma le mea liusuavai ole 75℃.I le lautele hydrophilic solvent e mafai foi ona soloia, mo esters gaʻo gaʻo, acrylic acid ma methylacrylate, faʻavevela foi e tele solubility, ae toetoe lava a le mafai ona soluble i solvents hydrophobic e pei o hydrocarbons, hydrocarbons halogenated.E mafai ona faʻaaogaina e avea o se sui faʻafesoʻotaʻi, faʻaaogaina lautele i le fiber suia resin, gaosia vali, faʻapipiʻi palasitika, faʻamautu eleele, ma isi.O se monomer fesoʻotaʻi faʻalava e faʻaaogaina lautele mo le faʻaogaina o fiber, faʻaogaina o resini, faʻapipiʻi, pepa, paʻu, faʻamaʻi togafitiga luga, ma e mafai foi ona faʻaaogaina e fai ma teuteuga eleele.

fa'aoga

O se mea mataʻutia mo le gaosia o le resini thermosetting, faʻamalama faʻamalama epoxy resin faʻapipiʻi, faʻafefete faʻafefe suauʻu ma faʻamago ufiufi.O lo'o fa'aogaina lona fa'aumu fa'apolopolo mo le fa'auma alava, ie, pa'u ma le fa'alava pepa.E faʻaaogaina foi e fai ma mea faʻapipiʻi mo laupapa, uʻamea, ma isi.
Fa'aaogaina e fai ma monomer feso'ota'i fa'alava mo le fa'a'ele'ele o le acrylic.Ole fua ole faʻapipiʻi faʻapipiʻi faʻamalosi emulsion e aofia ai le vaega carboxyl o le L% ~ 2% o le aofaʻi o le monomer, pe a sili atu i le 3%, o le a faʻaitiitia le viscosity muamua.Mo le faʻapipiʻi emulsion e aunoa ma le carboxyl group, o le fua lautele e le sili atu i le 5%.MMAM crosslinking tali vevela na o ia e maualuga, e masani lava 120 ~ 170 ℃, faʻaopoopoina o se proton-ituaiga catalyst e mafai ona faaitiitia le vevela crosslinking.Acrylic acid (AA) e mafai ona maua uma hydrogen protons, ma copolymerization ma acrylate, o lea MMAM e fausia ai se sui crosslinking composite ma AA, o le aofaiga o le 3:2 e sili atu.O le cross-linker HA e mafai ona suitulaga i le N-hydroxymethylacrylamide ma e leai ni formaldehyde.
