Polyvinylpyrrolidone PVPP Fa'afeso'ota'i Cas 25249-54-1
O le Polyvinylpyrrolidone cross-linked (PVPP) o se polymer cross-linked e le solo i le vai, acids malolosi, bases malolosi, ma solvents organic lautele, e fausia e ala i le polymerization o vinyl pyrrolidone monomers i lalo o tulaga faapitoa. I le avea ai o se oloa taua o le polymer fine chemical, e tele ona meatotino lelei ma tulaga ese le PVPP, ma ua lautele lona faʻaaogaina i mea teuteu, meaʻai, vailaʻau ma isi matata.

O le PVPP, o se oloa taua o vailaʻau faʻapolymer, e tele ona uiga lelei ma tulaga ese, ma o le polyvinylpyrrolidone ua faʻaaogaina lautele i mea teuteu, meaʻai, vailaʻau ma isi matāʻupu. Ona o le mamafa maualuga o le molecular ma le fausaga o le cross-linking o le cross-linked polyvinylketone, o le polyvinylpolypyrrolidone pvpp e le mafai ona solo i le vai ae e mafai ona vave mafua ai ona faʻalauteleina lona fausaga fesoʻotaʻiga ma faʻaleagaina pe a fetaiaʻi ma le vai. E faʻaaogaina lautele le PVPP o se sui e faʻaleagaina ai papamaa i vailaʻau, faʻapea foʻi ma se mea e faʻamautuina ai le faʻasusu, o se sui e faʻafefiloi ai vaega o vailaʻau, ma se sui e faʻafefiloi ai tannins ma polyphenols i vailaʻau e faʻavae i laʻau.
