Suʻesuʻega ma le faʻaaogaina o le Acrylamide

Acrylamideo loʻo i ai le carbon-carbon double bond ma le amide group, lea e iai le vailaʻau masani o le faʻalua faʻalua: e faigofie ona polymerize i lalo o le ultraviolet irradiation poʻo le vevela o le vevela; E le gata i lea, e mafai ona faʻaopoopo faʻatasi faʻalua i vailaʻau hydroxyl i lalo o tulaga alkaline e gaosia ai ethers. . Pe a faʻaopoopo i le amine muamua, e mafai ona faʻatupuina le faʻafefiloi faʻatasi poʻo le binary. A fa'aopoopo i le amine lona lua, e na'o le fa'afefiloi fa'atasi e mafai ona gaosia. Pe a faʻaopoopo i le amine maualuga, e mafai ona gaosia le masima ammonium quaternary. Faatasi ai ma le faʻaopoopoga o le ketone faʻaagaoioia, e mafai ona vave faʻataʻamilo le faʻafefiloi e fai ai le lactam. E mafai foi ona faʻaopoopoina i le sodium sulfite, sodium bisulfite, hydrogen chloride, hydrogen bromide ma isi mea faʻapitoa; O lenei oloa e mafai foi ona copolymerized, e pei o isi acrylates, styrene, vinyl halide copolymerization; E mafai foi ona faʻaitiitia le faʻaluaina e le borohydride, nickel boride, carbonyl rhodium ma isi mea faʻamalosi e maua ai le propionamide. E mafai ona gaosia le Diol e ala ile catalytic oxidation ma le osmium tetroxide.O le vaega amide o lenei oloa o loʻo i ai le vailaʻau masani ole aliphatic amide: tali atu i le sulfuric acid e fai ai masima; Ile iai ole alkaline catalyst, o ion acrylic sa hydrolyzed e fai. I le i ai o le acid catalyst, acid acid sa hydrolyzed. I le i ai o se mea e faʻamalo ai le vai, o le acrylonitrile e faʻamaʻaina. E tali atu i le formaldehyde e fausia ai le N-hydroxymethylacrylamide.

Acrylamideo se tasi o faiga sili ona taua ma sili ona faigofie acrylamide. E masani ona faʻaaogaina e pei o mea mataʻutia mo le faʻaogaina o meaola ma mea polymer. E solu le polymer i le vai, o lea e faʻaaogaina e gaosia ai.fugai le vai togafitiga, aemaise lava mo le flocculation o polotini, masoa i le vai ei ai se aafiaga lelei. I le faaopoopo atu i le flocculation, o loʻo i ai le mafiafia, faʻafefeteina, teteʻe, faʻasalalau ma isi mea sili ona lelei. A faʻaaogaina e avea o se faʻamaʻi palapala, e mafai ona faʻateleina le faʻaogaina o le vai ma le susu o le eleele.;Faʻaaogaina e fai ma faʻaopoopoga pepa faʻatumu, e mafai ona faʻateleina le malosi o le pepa, i le mea o le masoa, vai soluble ammonia resin; Fa'aaogaina e fai ma sui kemisi grouting, fa'aaogaina i le eliina o alavai fa'ainisinia sivili, suau'u suau'u viliina, mine ma dam inisinia plugging; Fa'aaogaina e fai ma fiber modifier, e mafai ona fa'aleleia mea fa'aletino o alava synthetic; Fa'aaogaina e fai ma fa'asao, e mafai ona fa'aoga mo vaega lalo o le eleele anticorrosion; E mafai foi ona faaaoga i mea'ai alamanuia faaopoopo, pigment dispersant, lomitusi ma vali pa'u.With phenolic resin solution, e mafai ona faia i le alava tioata fa'apipi'i, ma pa'u fa'atasi e mafai ona faia i le adhesive ma'ale'ale mamafa.Many mea synthetic e mafai ona saunia e polymerization ma vinyl acetate, styrene, vinyl chloride, acrylonitrile ma isi monomers. O lenei oloa e mafai foi ona faʻaaogaina e fai ma vailaʻau, vailaau faʻasaina, vali, vali mea mata.
