Ibikoresho bya Shimi
Sodium stearate ni ifu yera, gushonga gake mumazi akonje, kandi bigahita byihuta mumazi ashyushye, kandi ntibishobora guturika nyuma yo gukonjesha mumasabune ashyushye cyane.Ifite imbaraga nziza zo kwigana, gucengera no gukumira, ifite amavuta, kandi ifite impumuro nziza.Irashobora gushonga byoroshye mumazi ashyushye cyangwa mumazi ya alcool, kandi igisubizo ni alkaline kubera hydrolysis.
Gusaba
Imikoreshereze yingenzi ya sodium stearate: kubyimba;emulifier;gutatanya;ibifatika;inhibitori ya ruswa 1. Detergent: ikoreshwa mugucunga ifuro mugihe cyo kwoza.
2. Emulsifier cyangwa ikwirakwiza: ikoreshwa muri polymer emulisation na antioxydeant.
3. Inhibitori ya ruswa: Ifite ibintu birinda muri firime ipakira.
4. Amavuta yo kwisiga: kogosha gel, gufatira mu mucyo, nibindi.
5. Ibifatika: bikoreshwa nka kole isanzwe kugirango ushire impapuro.
Ibisobanuro
Sodium stearate ni umunyu wa sodium ya acide stearic, izwi kandi nka sodium octadecate, ikaba ikoreshwa cyane na anionic surfactant kandi igice kinini cyamasabune.Amazi ya hydrocarbyl muri molekile ya sodium stearate nitsinda rya hydrophobique, naho carboxyl moiety ni hydrophilique.Mu mazi yisabune, sodium stearate ibaho muri micelles.Micelles ni serefegitura kandi igizwe na molekile nyinshi.Amatsinda ya hydrophobique ari imbere kandi ahujwe nizindi mbaraga za van der Waals, naho hydrophilique ya hydrophilique iri hanze kandi ikwirakwizwa hejuru ya micelles.Micelles ikwirakwizwa mumazi, kandi mugihe uhuye namavuta adashobora gushonga, amavuta arashobora gukwirakwizwa mumavuta meza.Itsinda rya hydrophobique ya sodium stearate ishonga mumavuta, mugihe hydrophilique yahagaritswe mumazi kugirango yanduze.Mu mazi akomeye, ion ya stearate ihuza na calcium na magnesium ion kugirango ikore calcium-calcium idashobora gushonga hamwe numunyu wa magnesium, bigabanya ubukana.Usibye sodium stearate, isabune irimo sodium palmitate CH3 (CH2) 14COONa hamwe nunyunyu ya sodium yandi mavuta acide (C12-C20).
