Chemical Properties
Sodium stearate ihupfu chena, inonyungudika zvishoma mumvura inotonhora, uye inokurumidza kunyungudika mumvura inopisa, uye haivhenekeki mushure mekutonhodza mune yakanyatso kunyungudutswa sipo inopisa. Iine emulsifying yakanakisa, inopinda uye inodzivirira simba, ine girizi inonzwa, uye ine kunhuhwirira kwemafuta. Inonyungudika nyore nyore mumvura inopisa kana mvura inodhaka, uye mhinduro yacho ndeye alkaline nekuda kwehydrolysis.
Application
Kushandiswa kukuru kwe sodium stearate: thickener; emulsifier; dispersant; adhesive; corrosion inhibitor 1. Detergent: inoshandiswa kudzora furo panguva yekusuka.
2. Emulsifier kana dispersant: inoshandiswa ku polymer emulsification uye antioxidant.
3. Corrosion inhibitor: Iine zvidziviriro zvekudzivirira mu cluster packaging film.
4. Zvizoro: kuveura gel, kunamatira kwakajeka, nezvimwe.
5. Adhesive: inoshandiswa seyakasikwa glue kunama mapepa.
Tsanangudzo
Sodium stearate ndiyo sodium munyu we stearic acid, inozivikanwawo sesodium octadecate, iyo inowanzoshandiswa anionic surfactant uye chikamu chikuru chesipo. Iyo hydrocarbyl moiety mu sodium stearate molecule iboka re hydrophobic, uye iyo carboxyl moiety iboka re hydrophilic. Mumvura ine sipo, sodium stearate iripo mumamicelles. Iwo micelles ane denderedzwa uye anoumbwa nemamorekuru akawanda. Mapoka e hydrophobic ari mukati uye anosanganiswa nemumwe nemauto evan der Waals, uye mapoka e hydrophilic ari kunze uye akagoverwa pamusoro pemicelles. Iyo micelles inoparadzirwa mumvura, uye kana ikasangana nemvura-isina kunyungudika mafuta mavara, mafuta anogona kuparadzirwa mumadonhwe emafuta akanaka. Iro hydrophobic boka re sodium stearate inonyungudika mumafuta, nepo hydrophilic boka Rakamiswa mumvura kuti riparadzwe. Mumvura yakaoma, stearate ions inosanganiswa ne calcium uye magnesium ions kuita mvura-insoluble calcium uye magnesium munyu, kuderedza detergency. Pamusoro pe sodium stearate, sipo inewo sodium palmitate CH3(CH2)14COONa uye sodium munyu yemamwe mafuta acids (C12-C20).
