Falegaosimea ta'uta'ua maualuga Poly(1-vinylpyrrolidone-co-vinyl acetate)/VP/VA CAS:25086-89-9
Muamua ma sili, o lenei copolymer o loʻo i ai mea sili ona lelei e fai ata tifaga.E mafai ona fausia se ata tifaga manino ma sili ona pipii ma tumau.O le mea lea e lelei ai mo paʻu ma faʻapipiʻi faʻaaogaina i le tele o faʻaoga e aofia ai vali, varnishes ma varnishes.
E le gata i lea, o le vinylpyrrolidone-vinyl acetate copolymers o loʻo faʻaalia ai le solubility sili ona lelei i le vai ma le tele o vailaʻau faʻalaʻau.O lenei solubility e mafai ai ona faʻaaogaina e avea o se vailaʻau mafiafia i le tele o faʻatulagaga, e aofia ai mea faʻapitoa mo le tausiga o le tagata lava ia e pei o gels lauulu, pulumu ma lotions.O mea lelei faʻapipiʻi o lenei copolymer e avea foi ma mea taua i le gaosiga o laupepa ma capsules mo le fale gaosi oloa.
E le gata i lea, o le amio a le vinylpyrrolidone-vinyl acetate copolymers e mafai ona faʻaleleia e tusa ai ma manaʻoga faʻapitoa, ma faʻaogaina ai mo mea faʻaeletonika ma faʻapipiʻi faʻapipiʻi.O lona feso'ota'iga ma mea 'ese'ese e pei o metala, palasitika ma 'ie e fa'aopoopoina i lona agava'a ma le aoga.
E le gata i lea, o le vinylpyrrolidone-vinyl acetate copolymers e faʻamautu le vevela ma faʻasaʻo i le faʻavelaina o le UV, faʻamautinoa le tumau ma le umi o faʻatinoga mo faʻaoga i fafo.O le mea lea e avea ai ma filifiliga sili mo paʻu puipui i luga o fale, taʻavale ma mea faʻaeletoroni.
I le aotelega, o le vinylpyrrolidone-vinyl acetate copolymers o loʻo i ai ni mea e sili ona lelei e fai ai ata, solubility, eletise eletise, ma le mautu o le vevela, e ofoina atu le tele o avanoa mo pisinisi eseese.O ana fa'aoga e afua mai i mea fa'apipi'i ma fa'apipi'i i mea tau tausiga fa'aletagata ma mea fa'aeletonika.Matou te mautinoa o matou vinylpyrrolidone-vinyl acetate copolymers o le a faʻafeiloaʻi ma sili atu i ou faʻamoemoega ma o latou tulaga sili ona lelei ma faʻaauau pea.
