Fa'amatalaga Oloa
CAS: 79-10-7
1.Acrylic acid o le sili ona faigofie unsaturated carboxylic acid, faatasi ai ma se fausaga mole e aofia ai se vaega vinyl ma se vaega carboxyl.O le acid acid mama o se vai e leai se lanu, faʻamalamalamaina ma se manogi faʻafefe.Malosi 1.0511.Liu liusuavai 14°C.140.9°C.E maualuga le acidic.A'a.Solu i le vai, ethanol ma eter.Chemically active Chemicalbook.Faigofie ona fa'apolimerina i le pauta pa'epa'e manino.E gaosia le propionic acid pe a faʻaititia.E maua ai le 2-chloropropionic acid pe a fa'aopoopo i le hydrochloric acid.Faʻaaogaina i le sauniuniga o resins acrylic, ma isi. Faʻaaogaina foi i isi faʻasologa faʻasolosolo.Fa'atupuina e ala i le fa'ama'iina o le acrolein po'o le hydrolysis o le acrylonitrile, fa'apipi'iina fo'i mai le acetylene, carbon monoxide ma le vai, po'o le gaosia e ala i le fa'ama'iina o le ethylene ma le carbon monoxide i lalo o le mamafa.
2.Acrylic acid e mafai ona oʻo i le uiga faʻaalia o gaʻo carboxylic ma esters tutusa e mafai ona maua e ala i le tali atu ma ava malosi.O esters sili ona taatele e aofia ai le methyl acrylate, butyl acrylate, ethyl acrylate, ma le 2-ethyl.
3.Acrylic acid ma ona esters, i latou lava pe fefiloi ma isi monomers, faia polymerization e fausia homopolymers po copolymers.Monomers masani e mafai ona kopiina i le acid acid e aofia ai amides, Chemicalbook acrylonitrile, vinyl-containing, styrene ma le butadiene.O nei polymers e faʻaaogaina e gaosia ai le tele o palasitika, paʻu, faʻapipiʻi, elastomers, fola o le fola ma vali.
Fa'atatauga
1.Main vaega talosaga: (1) warp sizing mea saunia e acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate ma isi mea mata, Chemicalbook nai lo polyvinyl ava malosi sizing mea gafatia desizing, faasaoina masoa.(2) faʻapipiʻi faʻatasi ma acrylic acid, methyl acrylate, ethyl acrylate, acrylic acid-2-ethylhexyl ma isi latex copolymer, e mafai ona faʻaaogaina mo le electrostatic flocking, faʻapipiʻi faʻapipiʻi, lona mausali ma lagona lelei.(3) vai mafiafia ma propionic acid ma ethyl acrylate copolymer faia i le mamafa mole mamafa pauta.E mafai ona faʻaaogaina e fai ma sui mafiafia, faʻaaogaina i totonu o suauʻu, o tone taʻitasi o oloa e mafai ona faʻateleina le gaosiga o le 500t o le suauu mama, o le aʻafiaga o le toe faʻaleleia o le suauu i luga o vaieli tuai e sili atu.(4) faʻapipiʻiina pepa faʻamaeʻaina sui faʻamaʻi faʻamaʻi faʻamaʻi, butyl acrylate, acrylic acid-2-ethylhexyl ester, styrene ma isi quaternary copolymer latex mo le faʻapipiʻiina o pepa faʻapipiʻi, faʻatumauina lanu e aunoa ma le samasama, lelei lomitusi faatinoga, e le pipii rollers, sili atu nai lo styrene butyl latex e mafai ona faasaoina coolin mago.(5) polyacrylic acid salts e fa'aaoga ai le acrylic acids e mafai ona maua ai le tele o masima polyacrylic acids (e pei o le ammonium salts, sodium salts, potassium salts, alumini salts, nickel salts, ma isi).Faʻaaogaina e pei o le coagulant, vailaʻau togafitiga vai, dispersant, mafiafia, faʻasao meaʻai vailaʻau faʻamaʻi ma alkali resistant desiccant, faʻamaluluina sui ma isi ituaiga o polymer additives.
2. Sauniuniga o polymers e ala i le homopolymerization poʻo le copolymerization mo faʻapipiʻi, faʻapipiʻi, resini malosi, faʻapipiʻi faʻapipiʻi, ma isi.
