ʻO ke kaʻina hana o ka aila emulsification pili i ka ninini ʻana i ka aila a me ka wai i loko o kahi mixer mua i kahi ratio kikoʻī me ka ʻole o nā mea hoʻohui. Ma o ka ultrasonic emulsification, ka wai immiscible a me ka aila e hoʻololi kino wikiwiki, ka hopena i kahi wai keʻokeʻo milky i kapa ʻia ʻo "wai i ka ʻaila". Ma hope o ka hoʻomaʻamaʻa kino e like me ke kani kani ultrasonic, ka magnetization ikaika, a me Venturi, ua hoʻokumu ʻia kahi ʻano wai hou me ka minoʻaka (1-5 μm) o ka "wai i loko o ka ʻaila" a loaʻa ka hydrogen a me ka oxygen. ʻOi aku ma mua o 90% o nā ʻāpana emulsified ma lalo o 5 μm, e hōʻike ana i ke kūpaʻa maikaʻi o ka ʻaila kaumaha emulsified. Hiki ke mālama ʻia ma ka lumi wela no ka manawa lōʻihi me ka ʻole o ka haki ʻana i ka emulsion, a hiki ke hoʻomehana ʻia i 80 ℃ no nā pule he 3.
Hoʻonui i ka hopena emulsification
ʻO ke kani kani he ala kūpono e hōʻemi i ka nui o ka dispersion a me ka lotion. Ke kani ultrasonic emulsification lako hiki ke loaʻa ka lotion me ka liʻiliʻi ʻāpana nui (wale 0.2 – 2 μm) a haiki droplet nui mahele (0.1 – 10 μm). Hiki ke hoʻonui ʻia ka nui o ka lotion e 30% a 70% ma o ka hoʻohana ʻana i nā emulsifiers.
Hoʻonui i ka paʻa o ka lotion
I mea e hoʻopaʻa ai i nā droplets o ka mea hou i hoʻopuehu ʻia e pale i ka coalescence, hoʻohui ʻia nā emulsifiers a me nā stabilizers i ka lotion ma ke ʻano kuʻuna. Hiki ke loaʻa ka lotion paʻa ma o ka ultrasonic emulsification me ka liʻiliʻi a ʻaʻohe emulsifier.
Ka laulā o ka hoʻohana
Ua hoʻohana ʻia ka emulsification kani ultrasonic ma nā ʻano āpau. E like me nā mea inu ʻoluʻolu, ka ʻuala tōmato, ka mayonnaise, ka jam, ka waiu hana, ke kokoleka, ka aila saladi, ka aila a me ka wai kō, a me nā meaʻai hui ʻē aʻe i hoʻohana ʻia i ka ʻoihana meaʻai.
