Sodium Stearate no ka Anionic Surfactant a me nā Kopa

ʻO ka sodium stearate ka paʻakai sodium o ka waikawa stearic, i ʻike ʻia ʻo ka sodium octadecate, kahi mea hoʻohana maʻamau anionic surfactant a me ka mea nui o nā kopa.ʻO ka ʻāpana hydrocarbyl i loko o ka molekala sodium stearate he hui hydrophobic, a ʻo ka moiety carboxyl he hui hydrophilic.I ka wai kopa, aia ka sodium stearate i nā micelles.He poepoe ka micelle a ua haku ia me na mole.Aia nā pūʻulu hydrophobic i loko a ua hui pū ʻia me nā pūʻali van der Waals, a ʻo nā pūʻulu hydrophilic i waho a māhele ʻia ma ka ʻili o nā micelles.Hoʻopuehu ʻia nā micelles i ka wai, a i ka wā e ʻike ai i nā ʻaila ʻaila hiki ʻole ke hoʻoheheʻe ʻia, hiki ke hoʻopuehu ʻia ka ʻaila i loko o nā kulu aila maikaʻi.ʻO ka hui hydrophobic o ka sodium stearate e hoʻoheheʻe ʻia i loko o ka ʻaila, aʻo ka hui hydrophilic i hoʻopaʻa ʻia i ka wai no ka decontamination.I loko o ka wai paʻakikī, hui pū nā ion stearate me nā ion calcium a me ka magnesium e hana i ka calcium a me ka paʻakai magnesium hiki ʻole i ka wai, e hōʻemi ana i ka detergency.Ma waho aʻe o ka sodium stearate, loaʻa pū ka kopa i ka sodium palmitate CH3(CH2)14COONa a me nā paʻakai sodium o nā mea momona ʻē aʻe (C12-C20).
