Polyvinylpyrrolidone Cross-hononga PVPP Cas 25249-54-1
Ko te polyvinylpyrrolidone cross-linked (PVPP) he polymer hono-whakawhiti e kore e rewa i roto i te wai, waikawa kaha, turanga kaha, me nga whakarewa waro whanui, i hangaia e te polymerization o nga monomers vinyl pyrrolidone i raro i nga tikanga motuhake. He hua matū pai polymer nui, he maha nga ahuatanga tino pai me te ahurei a PVPP, a kua whakamahia nuitia ki nga mahi whakapaipai, kai, rongoa me etahi atu mara.

Ko te PVPP, he hua matū pai polymer nui, he maha nga ahuatanga pai me te ahurei, a kua whakamahia nuitia ki nga mahi whakapaipai, kai, rongoa me etahi atu mara. Na te nui o te taumaha ngota me te hanganga hono-whakawhiti o te polyvinylketone hono-whakawhiti, karekau e rewa i roto i te wai engari ka tere te whakawhanui i tana hanganga whatunga ka pakaru i te wa e pa ana ki te wai. Ko te PVPP e whakamahia nuitia ana hei kaihoko whakakorenga mo nga papa i roto i te rongoa, me te whakapumau i te aukati, he kaihoko whakahiato mo nga waahanga rongoa, me te kaihoko whakahiato mo nga tannins me nga polyphenols i roto i nga raau tipu.
