I-Sodium Stearate yi-powder emhlophe, incane kancane emanzini abandayo, futhi isheshe incibilike emanzini ashisayo, futhi ayishayeki ngemuva kokupholisa isisombululo esijulile sensipho esishisayo. Inamandla amahle kakhulu e-emulcing, angena futhi avimbayo, anomuzwa onamafutha, futhi unephunga elinamafutha. Kuyancibilika kalula emanzini ashisayo noma amanzi wotshwala, futhi ikhambi yi-alkali ngenxa ye-hydrolysis.
Ukusetshenziswa okuyinhloko kwe-sodium stearate: mkhulu; emulsifier; ehlakazekile; ukunamathela; I-Corososion inhibitor 1. Drickergent: Kusetshenziselwa ukulawula i-foam ngesikhathi sokulungiswa.
2. I-Emulsifier noma i-Dispersant: Isetshenziselwa i-polymer emulsation kanye ne-antioxidant.
3. I-Corrosion inhibitor: Inezindawo zokuvikela efilimu lokupakisha le-cluster.
4. Izimonyo: ukushefa ijeli, ukunamathela okusobala, njll.
I-5. Adhesive: Kusetshenziswa njenge-glue yemvelo ukunamathisela iphepha.
I-Sodium Stearate i-sodium usawoti we-stearic acid, eyaziwa nangokuthi i-sodium octadecate, okuyinto esetshenziselwa i-anionic esetshenziswayo kanye nengxenye enkulu yezinsipho. I-Hydrocarbyl moaress in the sodium stearate molecule iyiqembu le-hydrophobic, kanti i-carboxyl moossed yiqembu le-hydrophilic. Emanzini anensipho, ukuthambisa i-sodium kukhona eMichelles. IMicelles iyindilinga futhi yahlanganiswa ama-molecule amaningi. Amaqembu e-hydrophobic angaphakathi futhi ahlanganiswe komunye nomunye ngamabutho we-van der Waals, futhi amaqembu e-hydrophilic angaphandle futhi asatshalaliswa ebusweni beMi Minells. IMiceres ihlakazeka emanzini, futhi lapho ihlangabezana namabala kawoyela angakhohlisi, uwoyela angahlakazeka kumaconsi amafutha amahle. Iqembu le-hydrophobic le-sodium strate lincibilika emafutheni, kuyilapho iqembu le-hydrophilic limiswa emanzini ukuze liqashelwe. Ngamanzi anzima, i-sterate ion ihlangana ne-calcium kanye ne-magnium ion ukwenza i-calcium-infoluble infoluble kanye nosawoti we-magnesium, ukunciphisa ukungcola. Ngaphezu kwe-sodium stearate, insipho futhi iqukethe i-sodium plalmitate CH3 (CH2) 14COONA kanye nosawoti we-sodium kwamanye ama-acid ama-acid (C12-C20).
