Chii chinonzi Sodium Dehydroacetate CAS 4418-26-2?

Sodium dehydroacetate ipfu chena yekristaro inonyungudika nyore nyore mumvura. Inoratidza acidity isina simba mumvura uye inogona kuburitsa SO2 gasi kana paine acidity. Sodium dehydroacetate inodzivirira chikafu ine mabhakitiriya akawanda uye ine simba rekudzivirira chirwere, ine simba guru rekudzivirira chirwere chefungus nembiriso. Pamuyero mumwe chete, simba rekudzivirira chirwere rinopfuura kakawanda kana kuti kagumi kupfuura sodium benzoate nepotassium sorbate zvinoshandiswa zvakanyanya. Chinonyanya kukosha ndechekuti haina simba guru rekudzivirira chirwere pabhakitiriya rinogadzira acid, kunyanya mabhakitiriya elactic acid.

Kushandiswa

1. Sodium dehydroacetate mushonga unorwisa mabhakitiriya une kuchengetedzeka kwakanyanya, une mhando dzakasiyana dzemabhakitiriya, uye une simba guru remabhakitiriya. Haunyanyi kukanganiswa neacidity kana alkalinity yechikafu uye unogona kuchengetedza simba rakawanda remabhakitiriya kana uine acidic kana alkaline zvishoma. Kugona kwayo mabhakitiriya kuri nani pane sodium benzoate, potassium sorbate, calcium propionate, nezvimwewo, zvichiita kuti ive mushonga unodzivirira chikafu.
2. Sodium dehydroacetate inogona kushandiswa pakurapa pamusoro pesimbi, kubvisa mafuta, uye kudzivirira ngura pamusoro pesimbi,
3. Sodium dehydroacetate inogona kushandiswawo pakuongorora makemikari uye kugadzira mordants.
4. Sodium dehydroacetate inoshandiswawo muminda yekugadzira mapepa, dehwe, machira, zvizoro, nezvimwewo.
