Chii chinonzi Sodium Dehydroacetate CAS 4418-26-2?

Sodium dehydroacetate ichena crystalline poda inonyungudika nyore mumvura. Iyo inoratidzira isina kusimba acidity mumvura uye inogona kusunungura SO2 gasi pasi pemamiriro ane acidic. Sodium dehydroacetate ndeye yakafara-spectrum uye yakanyanya antibacterial chikafu chekuchengetedza, ine kunyanya yakasimba inhibitory kugona kurwisa mold uye mbiriso. Panguva imwe cheteyo, iyo antibacterial effect yakawedzera kakawanda kana makumi enguva dzakakwirira kudarika inoshandiswa zvakanyanya sodium benzoate uye potassium sorbate. Chinonyanya kukosha ndechekuti ine zvishoma inhibitory mhedzisiro yeasidhi inoburitsa mabhakitiriya, kunyanya lactic acid mabhakitiriya.

Application

1.Sodium dehydroacetate inonzi antibacterial agent ine kuchengetedzwa kwepamusoro, yakafara antibacterial range, uye yakasimba antibacterial kukwanisa. Iyo haina kukanganiswa ne acidity kana alkalinity yechikafu uye inogona kuchengetedza yakakwirira antibacterial efficacy pasi pe acidic kana zvishoma alkaline mamiriro. Kugona kwaro kweantibacterial kunopfuura sodium benzoate, potassium sorbate, calcium propionate, nezvimwewo, zvichiita kuti ive yakanaka kuchengetedza chikafu.
2. Sodium dehydroacetate inogona kushandiswa kugadzirwa kwesimbi pamusoro, kubvisa, uye kudzivirira ngura pasimbi,
3. Sodium dehydroacetate inogonawo kushandiswa pakuongorora kwemakemikari uye kugadzirirwa kwema mordants.
4.Sodium dehydroacetate inoshandiswawo muminda yekugadzira mapepa, matehwe, machira, zvizorwa, nezvimwe.
