Chemical Properties
I-sodium stearate iyimpushana emhlophe, inyibilika kancane emanzini abandayo, futhi incibilika ngokushesha emanzini ashisayo, futhi ayicwebezeli ngemva kokupholisa esixazululo sensipho eshisa kakhulu. Inamandla amahle kakhulu okwenza i-emulsifying, angena futhi avimbele, inomuzwa onamafutha, futhi inephunga elinamafutha. Incibilika kalula emanzini ashisayo noma emanzini anotshwala, futhi isisombululo sine-alkaline ngenxa ye-hydrolysis.
Isicelo
Ukusetshenziswa okuyinhloko kwe-sodium stearate: ukuqina; i-emulsifier; i-disperant; okunamathelayo; corrosion inhibitor 1. Umshini wokuhlanza: osetshenziselwa ukulawula igwebu ngesikhathi sokuwasha.
2. I-Emulsifier noma i-disperant: isetshenziselwa i-polymer emulsification kanye ne-antioxidant.
3. I-Corrosion inhibitor: Inezici zokuzivikela kufilimu yokupakisha yeqoqo.
4. Izimonyo: ijeli yokushefa, i-adhesive esobala, njll.
5. I-Adhesive: isetshenziswa njengeglue yemvelo ukunamathisela iphepha.
Incazelo
I-sodium stearate usawoti we-sodium we-stearic acid, owaziwa nangokuthi i-sodium octadecate, esetshenziswa kakhulu i-anionic surfactant kanye nengxenye eyinhloko yensipho. I-hydrocarbyl moiety ku-sodium stearate molecule iyiqembu le-hydrophobic, futhi i-carboxyl moiety iyiqembu le-hydrophilic. Emanzini anensipho, i-sodium stearate ikhona kuma-micelles. Ama-micelles ayindilinga futhi akhiwe ama-molecule amaningi. Amaqembu e-hydrophobic angaphakathi futhi ahlanganiswe namanye amabutho e-van der Waals, futhi amaqembu angama-hydrophilic angaphandle futhi asakazwa ebusweni bama-micelles. Ama-micelles ahlakazeka emanzini, futhi lapho ehlangabezana namabala kawoyela angancibiliki emanzini, uwoyela ungahlakazwa ube amaconsi kawoyela amahle. Iqembu le-hydrophobic le-sodium stearate lincibilika kuwoyela, kuyilapho iqembu le-hydrophilic Limiswe emanzini ukuze lisuswe ukungcola. Emanzini aqinile, ama-ion e-stearate ahlangana ne-calcium ne-magnesium ions ukwakha i-calcium engancibiliki emanzini kanye nosawoti we-magnesium, okunciphisa ukubola. Ngaphezu kwe-sodium stearate, insipho iphinde ibe ne-sodium palmitate CH3(CH2)14COONA kanye nosawoti we-sodium wamanye ama-fatty acids (C12-C20).
