ʻOi aku ka maikaʻi o ka wikiwiki o ka emulsifier?

He mea koʻikoʻi nā emulsifiers vacuum i ka ʻōnaehana hui ʻana o nā mea hana ʻoihana, ʻoi loa i ka hui ʻana i ka wai paʻa, ka hui wai-wai, emulsification aila-wai, dispersion a homogenization, shear grinding a me nā mea ʻē aʻe. ʻO ke kumu i kapa ʻia ai he mīkini emulsifying no ka mea hiki ke hoʻokō i kahi hopena emulsifying. Hoʻokumu ʻia ka emulsion aila-wai ma hope o ka hui pū ʻana o ka ʻāpana ʻelua, a ua māhele ʻia i ʻelua ʻōnaehana: wai-i-ʻaila a i ʻole wai-i-ʻaila. No ka hoʻokō ʻana i ka emulsification, aia ma lalo o ʻelua mau koi:

ʻO ka mea mua, he hopena dispersing ikaika ka ʻoki mīkini. ʻO ka ʻāpana wai a me ka ʻaila ʻaila i loko o ka wai wai e ʻoki ʻia i loko o nā ʻāpana liʻiliʻi i ka manawa like, a laila hoʻohui pū ʻia i ka wā o ke komo ʻana a me ka hui ʻana e hana i kahi emulsion.

ʻO ka lua, ʻo kahi emulsifier kūpono e hana ma ke ʻano he alahaka waena ma waena o nā molekele aila a me ka wai. Ma o ka hana o ka uila a me ka intermolecular ikaika, ka aila-wai hui emulsion hiki ke mālama stably no ka manawa i koi 'ia.

ʻO ka ikaika o ka hana shearing o ka emulsifier pili pono i ka fineness. Ma o ka nānā ʻana, aia ka nui o ka ʻoi, paʻakikī, stator gap, ka wikiwiki pili o nā ʻāpana ʻoki ʻelua a me ka nui o ka ʻāpana i ʻae ʻia, a me nā mea ʻē aʻe. hilinaʻi nui ʻia nā waiwai i ka nui o ka ʻāpana a ʻaʻole makemake e hoʻololi, no laila, ʻo ka wikiwiki pili o nā lau he kumu koʻikoʻi, i hōʻike ʻia e like me ka wikiwiki circumferential o ka rotor. (no ka mea, paʻa ka stator). Inā ʻoi aku ka kiʻekiʻe o ka wikiwiki, ʻoi aku ka kiʻekiʻe o ka ʻoki ʻana a i ʻole ka hoʻoheheʻe ʻana i ka wai kahe radial, no laila e ikaika ka hopena dilution, a ʻo ia hoʻi. Eia naʻe, ʻoi aku ka kiʻekiʻe o ka laina laina, ʻoi aku ka maikaʻi. Ke hiki i ka waiwai kiʻekiʻe loa, aia ka manaʻo e hoʻōki i ke kahe, no laila e liʻiliʻi loa ke kahe, kiʻekiʻe loa ka wela, a e hōʻiliʻili kekahi mau mea, e alakaʻi ana i nā hopena suboptimal.
