Mea hana emulsifying
ʻO ka mīkini hana nui no ka hoʻomākaukau ʻana i ka emulsion ka mīkini emulsifying, ʻo ia ke ʻano o ka emulsifying mea hana no ka hui ʻana i ka ʻaila a me ka wai. I kēia manawa, ʻekolu mau ʻano nui o ka mīkini emulsifying: emulsifying mixer, colloid mill a me homogenizer. Emulsifying machine type and structure, performance and the size of the emulsion particles (dispersion) and the quality of the emulsion (stability) has a great relationship. ʻO ka maʻamau, e like me kēia manawa i hoʻohana nui ʻia i ka hale hana hoʻonaninani e hoʻoulu ai i ka emulsifier, ka emulsion i hana ʻia e ka dispersion maikaʻi ʻole. ʻO nā ʻāpana he nui a koʻikoʻi, me ka paʻa maikaʻi ʻole a me ka haumia maʻalahi. Akā maʻalahi kāna hana ʻana, ʻoi aku ka liʻiliʻi o ke kumukūʻai, ʻoiai ʻoe e hoʻolohe i ke ʻano kūpono o ka mīkini, e hoʻohana pono, akā hiki nō hoʻi ke hana i nā koi koʻikoʻi maʻamau o nā mea hoʻonaninani kaulana. ʻO ka wili colloid a me ka homogenizer ʻoi aku ka maikaʻi o nā mea emulsifying. I nā makahiki i hala iho nei, ua holomua nui ka mīkini emulsifying, e like me ka mīkini emulsifying vacuum, ka emulsion i hoʻomākaukau ʻia e ka dispersion a me ka paʻa o ka maikaʻi.
ʻO ka mahana
He mana nui ka emulsification emulsification i ka emulsification, akā ʻaʻohe palena paʻa i ka mahana. Inā he wai ka aila a me ka wai, hiki ke hoʻoheheʻe ʻia ma ka hoʻoulu ʻana i ka lumi wela. ʻO ka maʻamau, pili ka mahana emulsification i ka helu heheʻe o nā mea me ka helu heheʻe kiʻekiʻe i nā pae ʻelua, a pono e noʻonoʻo ʻia nā mea e like me ke ʻano o ka emulsifier a me ka solubility o ka pae aila a me ka pae wai. Eia kekahi, pono e mālama ʻia ka mahana o nā ʻāpana ʻelua, ʻoi aku hoʻi no nā ʻāpana wax a me nā mea momona me ka helu heheʻe kiʻekiʻe (ma luna o 70 ℃), i ka wā e emulsifying, ʻaʻole pono e hoʻohui ʻia ka pae wai haʻahaʻa haʻahaʻa, i mea e pale i ka wax a me ka momona mai ka crystallizing ma mua o ka emulsification, ka hopena i ka nui a i'ole ke ko'iko'i a me ka like ole emulsion. ʻO ka mea maʻamau, i ka wā emulsifying, hiki ke hoʻomalu ʻia ka mahana o ka aila a me ka wai ma waena o 75 ℃ a me 85 ℃. Inā he kiʻekiʻe ka ʻaila hehee a me nā mea ʻē aʻe, ʻoi aku ka kiʻekiʻe o ka emulsifying i kēia manawa. Eia kekahi, inā piʻi nui ka viscosity i ke kaʻina hana emulsification, ʻo ka mea i kapa ʻia he mānoanoa loa a pili i ka hui ʻana, hiki ke hoʻokiʻekiʻe ʻia kekahi mahana emulsification. Inā loaʻa kahi emulsifier i hoʻohana ʻia i kahi mahana hoʻololi, ʻoi aku ka maikaʻi o ke koho ʻana i ka mahana emulsifying a puni ka mahana hoʻololi. Hoʻopili ka mahana emulsification i kekahi manawa i ka nui o ka emulsion. Inā hoʻohana mau ʻia ka anionic emulsifier o ka kopa momona momona, ʻo ka nui o ka emulsion ma kahi o 1.8-2.0μm ke hoʻomalu ʻia ka mahana emulsification ma 80 ℃. Inā he 6μm ka nui o ka nui i ka wā e lawe ʻia ai ka emulsification ma 60 ℃. He nāwaliwali ka hopena o ka emulsification wela ma ka nui o ka ʻāpana ke hoʻohana ʻia ka emulsifier non-ionic no ka emulsification.
Ka manawa emulsifying
ʻO ka manawa emulsification maopopo ka hopena i ka maikaʻi o ka emulsion, a ʻo ka hoʻoholo ʻana o ka manawa emulsifying e like me ka nui o ka lākiō o ka pae wai wai, ʻelua ʻāpana viscosity a hoʻohua i ka viscosity o ka emulsion, ke ʻano a me ke ʻano o ka emulsifier, emulsifying. mahana, emulsifying manawa o ka nui, ua lawa e hana i ka'ōnaehana o ka emulsification, ua pili loa i ka pono o ka emulsification lako, Emulsification manawa hiki ke hoʻoholo e like me ka hoao ana a me ka hoʻokolohua. Emulsification me homogenizer (3000 RPM) lawe wale 3-10 minuke.
ʻO ka māmā hui
ʻO nā mea hana emulsification he mana nui i ka emulsification, ʻo kekahi o ia ka mana o ka hoʻoulu ʻana i ka wikiwiki i ka emulsification. ʻO ka wikiwiki o ka hoʻoulu ʻana, ʻo ia ka hana ʻana i ka ʻaila a me ka wai i hui pū ʻia, haʻahaʻa haʻahaʻa haʻahaʻa, maopopo ʻaʻole hiki ke hoʻokō i ke kumu o ka hui pū ʻana, akā kiʻekiʻe loa ka hoʻoulu ʻana i ka wikiwiki, e lawe mai i nā ʻōpū i loko o ka ʻōnaehana, a lilo ia i ʻekolu- ʻōnaehana pae, a hana i ka emulsion paʻa ʻole. No laila, pono e pale ʻia ka ea i ka hui ʻana, a ʻoi aku ka maikaʻi o ka mīkini emulsifying.
