mea hoʻohuihui M30/A-102W
ʻO ka Emulsifier kahi ʻano mea e hiki ai ke hana i ka hui ʻana o ʻelua a ʻoi aku paha nā ʻāpana immiscible e hana i kahi emulsion paʻa. ʻO kāna kumu hana ma ke kaʻina hana o ka emulsion, ʻo ka pae hoʻopuehu ʻia ma ke ʻano o nā droplets (microns) i hoʻopuehu ʻia i ka pae hoʻomau, hoʻemi ia i ka tension interfacial o kēlā me kēia ʻāpana i loko o ka ʻōnaehana hui ʻia, a ʻo ka ʻili droplet e hana i kahi kiʻiʻoniʻoni paʻa a i ʻole ma muli o ka uku o ka emulsifier i hāʻawi ʻia i loko o ka hoʻokumu ʻana o ka papa pālua uila, e pale i nā droplets e hōʻiliʻili kekahi i kekahi, a e mālama i ka emulsion like. Mai kahi manaʻo pae, he heterogeneous nō ka emulsion. Hiki i ka pae hoʻopuehu ʻia i loko o ka emulsion ke pae wai a i ʻole ka pae aila, ʻo ka hapa nui he pae aila. Hiki i ka pae hoʻomau ke ʻaila a i ʻole ka wai, a ʻo ka hapa nui o lākou he wai. ʻO ka emulsifier kahi surfactant me kahi hui hydrophilic a me kahi hui lipophilic i loko o ka mole. I mea e hōʻike ai i nā waiwai hydrophilic a lipophilic paha o ka emulsifier, "waiwai kaulike hydrophilic lipophilic (waiwai HLB)" hoʻohana pinepine ʻia. ʻO ka haʻahaʻa o ka waiwai HLB, ʻoi aku ka ikaika o nā waiwai lipophilic o ka emulsifier. Ma ke ʻano ʻē, ʻo ke kiʻekiʻe o ka waiwai HLB, ʻoi aku ka ikaika o ka hydrophilicity. Loaʻa i nā emulsifiers like ʻole nā waiwai HLB like ʻole. I mea e loaʻa ai nā emulsions paʻa, pono e koho ʻia nā emulsifiers kūpono.
