Fa'atomuaga ma foliga o oloa

O le N-hydroxymethylacrylamide o se pauta paʻepaʻe tioata. O le mafiafia faʻatatau e 1.185 (23/4 ℃), ma o le tulaga faʻaliusuā e 75 ℃. I le lautele, e mafai foʻi ona faʻataʻapeʻapeina le solvent hydrophilic, mo fatty acid esters, acrylic acid ma le methylacrylate, e tele foʻi le solubility o le faʻavevela, ae toetoe lava a le mafai ona faʻataʻapeʻapeina i solvent hydrophobic e pei o hydrocarbons, halogenated hydrocarbons. E mafai ona faʻaaogaina o se sui faʻafesoʻotaʻi, e faʻaaogaina lautele i le fiber modified resin, processing dye, plastic binder, soil stabilizer, ma isi. O le molecule o le oloa e iai se fusi faʻalua e fesoʻotaʻi ma le carbonyl group ma se reactive hydroxyl methyl group. O se monomer faʻafesoʻotaʻi e faʻaaogaina lautele mo le faʻaleleia o fiber, resin processing, kelu, pepa, paʻu, uʻamea surface treatment agent, ma e mafai foʻi ona faʻaaogaina o se faʻaleleia o le eleele.

fa'aaogā

O se mea mata e fa'aaogā mo le gaosiga o le thermosetting resin, light curing epoxy resin coating, o le e tete'e atu i le suāuu ma le o le mago. O lona copolymerization emulsion e fa'aaogā mo le fa'auma o le fiber, ie, pa'u ma le pepa. E fa'aaogā fo'i o se mea fa'apipi'i mo laupapa, u'amea, ma isi mea fa'apena.
Fa'aaogaina o se monomer fa'apipi'i mo le acrylic emulsion. O le fua o le acrylic emulsion pressure sensitive adhesive o lo'o i ai le carboxyl group e L % ~ 2% o le aofa'i atoa o le monomer, afai e sili atu i le 3%, o le a matua fa'aitiitia le viscosity muamua. Mo le emulsion adhesive e aunoa ma le carboxyl group, o le fua lautele e le sili atu i le 5%. O le vevela o le MMAM crosslinking reaction e maualuga atu, e masani lava 120 ~ 170℃, o le fa'aopoopoina o se proton-type catalyst e mafai ona fa'aitiitia ai le vevela o le crosslinking. O le acrylic acid (AA) e mafai ona tu'uina atu ai le hydrogen protons, ma le copolymerization ma le acrylate, o lea e sili atu ai le MMAM e fausia ai se composite crosslinking agent ma le AA, o le aofa'i o le 3:2. O le cross-linker HA e mafai ona suia le N-hydroxymethylacrylamide ma e le o iai le formaldehyde.

afifi ma felauaiga

B. E mafai ona faʻaaogaina lenei oloa, 25KG, ATO
C. Teu i totonu o se nofoaga malūlū, mago ma ea lelei. E tatau ona tapuni lelei pusa pe a uma ona fa'aoga a'o le'i fa'aaogaina.
D. E tatau ona fa'amaufa'ailoga lelei lenei oloa i le taimi o felauaiga e puipuia ai le susu, alkali malolosi ma 'aisa, timu ma isi mea leaga mai le fefiloi.
