Propylene Glycol Alginate PGA | 9005-37-2

(1) Ibara rya Propylene glycol alginate (PGA) ni ubwoko bushya bwinyongera bwibiryo byiza. Ikorwa mugutunganya byimbitse acide ya alginic yakuwe mubyatsi byo mu nyanja. Kugaragara ni ifu yera cyangwa yoroheje yumuhondo. Bikunze gukoreshwa nko kubyimba, gutuza no emulisiferi kubicuruzwa byibinyobwa.
. ; Kuberako iki gicuruzwa kitari ionic compound, nacyo gihamye cyane mubyuma bimwe na bimwe byuma kandi ntibizakomera kandi bigwa.
. Irashobora gushonga mumazi ikanagabanya umuti wa acide organic, ariko ntigishobora gushonga muri methanol, Ethanol, benzene nindi miti ikomoka kumubiri, ariko ibicuruzwa biva mubice bimwe bishobora gushonga mumuti wa Ethanol urimo ibintu bitarenze 60%. Agaciro kayo pH ni 3-4 (1% yumuti wamazi), biroroshye gukuramo ubuhehere, ihinduka umukara iyo ishyutswe kuri 55 ° C, karubone iba kuri 220 ° C, naho ivu rikaba kuri 400 ° C. Ubucucike bwacyo ni 1.46. Ntabwo ari geles cyangwa igwa mumuti wa acide ya pH 3-4.
