Mankhwala
Sodium stearate ndi ufa woyera, sungunuka pang'ono m'madzi ozizira, ndikusungunuka mwachangu m'madzi otentha, ndipo osalira pambuyo pozizira kwambiri yankho lotentha kwambiri. Ali ndi mphamvu zabwino kwambiri, zolowera komanso zopeputsa, zimakhala ndi zonunkhira, ndipo zimakhala ndi fungo lamafuta. Imasungunuka mosavuta m'madzi otentha kapena madzi oledzera, ndipo yankho lake ndi lalkaline chifukwa cha hydrolysis.
Karata yanchito
Ogwiritsa ntchito sodium stearate: Thickener; emulsifier; wobalalika; zomatira; Trussion inrobitor 1. Zoyala: zomwe zimagwiritsidwa ntchito kuwongolera chithovu nthawi yakucha.
2. Emulsiferier kapena Sturshunt: Amagwiritsidwa ntchito polylmezation ndi antioxidant.
3.
4. Zodzikongoletsera: Kumeta gel, zomata zomata, etc.
5. Zomatira: zogwiritsidwa ntchito ngati guluu wa pangani pepala.
Kaonekeswe
Sodium Stearate ndi mchere wa sodium wa stearic acid, omwe amadziwikanso kuti sodium octidecate, omwe amagwiritsidwa ntchito kwambiri owonjezera anyezi. Hydrocarcarbyl modedium mu sodium stearate molekyu ndi gulu la hydrophobic, ndipo carboxyl molem ndi gulu la hydrophilic. Mu madzi a sopo, sodium stearate ilipo m'michere. Micleles ndi wozungulira komanso wopangidwa ndi mamolekyulu ambiri. Magulu a hydrophobic amakhala mkati ndipo amaphatikizidwa wina ndi mnzake ndi a van der Waals, magulu a hydrophilic amakhala kunja ndikugawidwa padziko lapansi. Michiro imabalalika m'madzi, ndipo ikakumana ndi madontho ophatikizika ndi madzi, mafuta amatha kubalalitsidwa m'malo mwamiyala yamafuta. Gulu la hydrophobic la sodium stearate limasungunula mu mafuta, pomwe gulu la hydrophilic limayimitsidwa m'madzi kuti athe. M'madzi olimba, osungunuka amaphatikiza ma calcium ndi magnesium ndi magnesium kuti apange calcium yopanda madzi ndi mchere, kuchepetsa zowonjezera. Kuphatikiza pa sodium stearate, sopo ilinso ndi sodium kalmium ch3 (ch2) 14coona ndi mchere wa sodium wa asidi wina wamafuta (C12-C20).
