High Shear Emulsifier: ʻO ka hopena hope loa no ka hui pū ʻana

Ma ke kahua o ka hana ʻenehana, ʻo nā emulsifiers shear kiʻekiʻe ka hopena hope loa no ka hoʻokō ʻana i kahi hui like ʻole a paʻa o ʻelua mau wai immiscible. Hoʻolālā ʻia kēia mau mīkini ikaika no ka hoʻoulu ʻana i nā mana mechanical a hydraulic ikaika e wāwahi i nā kulu wai i loko o nā liʻiliʻi liʻiliʻi, ʻoi aku ka nui o nā ʻano like ʻole, e hana ana i nā emulsion paʻa.

ʻO ke kī i ka kūleʻa o kahi emulsifier kiʻekiʻe-shear ʻo ia ka hiki ke hoʻoulu i ka haunaele a me ka shear, kahi mea koʻikoʻi no ka wāwahi ʻana i nā kulu a hoʻopuehu iā lākou i ka wā mau. ʻO kēia ka hopena i kahi hui paʻa a homogeneous, he mea nui ia no nā ʻoihana he nui e pili ana i nā lāʻau lapaʻau, nā meaʻai a me nā mea inu, nā mea hoʻonaninani a me nā kemika.

ʻO ka emulsifier kiʻekiʻe-shear i hoʻolakoʻia me kahi pūnaewele rotor-stator kiʻekiʻe,ʻo ia ka puʻuwai o ka mīkini. Hoʻokumu ka rotor kiʻekiʻe kiʻekiʻe i ka hoʻoheheʻe ʻana, e huki ana i ka wai i nā wahi ʻoki kiʻekiʻe. I ka manawa like, hoʻokumu ʻia kahi stator me nā ʻano niho i hoʻolālā maikaʻi ʻia e hana i nā pūʻali koa ikaika e wāwahi i nā kulu a hoʻopuehu iā lākou i loko o ka wai. ʻO ka hopena he emulsion maikaʻi a kūpaʻa e kū ana i nā kūlana koʻikoʻi.

ʻO kekahi o nā pono nui o ka hoʻohana ʻana i ka emulsifier shear kiʻekiʻe ʻo ia ka hiki ke hana i nā emulsion paʻa i loko o nā minuke. He ʻokoʻa kēia me nā ʻano hana ʻē aʻe, e like me ka hoʻoulu ʻana maʻalahi a i ʻole ka hui ʻana haʻahaʻa, hiki ke lōʻihi a ʻaʻole i loaʻa nā hopena ʻoluʻolu. Eia kekahi, hiki i nā emulsifiers shear kiʻekiʻe ke mālama i ka nui o nā viscosities a hiki ke hoʻohui maikaʻi i ka wai a me nā wai i hoʻokumu ʻia i ka aila, e hana ana iā lākou i mea waiwai nui no ka nui o nā noi.

No ka laʻana, ma ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia nā emulsifiers kiʻekiʻe-shear e hana i nā emulsions paʻa o nā mea lāʻau lapaʻau ikaika me nā wai ʻē aʻe, e like me ka aila a i ʻole ka wai. Hoʻohana ʻia ka emulsion i loaʻa i nā huahana lāʻau lapaʻau like ʻole, e like me nā creams, lotions, a me nā ʻaila. I ka ʻoihana meaʻai a me nā mea inu, hoʻohana ʻia nā emulsifiers kiʻekiʻe-shear e hana i nā emulsion paʻa i nā huahana e like me ka mayonnaise, nā pāpale salakeke a me nā meaʻai emulsified.

I loko o ka ʻoihana hoʻonaninani, pono nā emulsifiers kiʻekiʻe-shear e hana i nā emulsion paʻa a kūlike i nā huahana e like me ka creams, lotions a me nā gels. He mea koʻikoʻi ka hiki ke hana i nā lotions kiʻekiʻe e hōʻoia i ka pono a me ka paʻa o kēia mau huahana a me ka hoʻokō ʻana i nā kūlana koʻikoʻi koʻikoʻi o ka ʻoihana.

I ka hōʻuluʻulu ʻana, ʻo nā emulsifiers shear kiʻekiʻe ka hopena hope loa no ka loaʻa ʻana o nā hui like ʻole a paʻa o nā wai immiscible. ʻO ko lākou hiki ke hana i nā emulsion paʻa i loko o nā minuke, mālama i kahi ākea o nā viscosities, a hoʻohui maikaʻi i ka wai a me ka wai i hoʻokumu ʻia i ka aila e lilo ai lākou i mea waiwai i nā ʻoihana lehulehu. Inā i loko o ka lāʻau lapaʻau, ka meaʻai a me ka mea inu, nā mea hoʻonaninani a i ʻole nā ​​​​ʻoihana kemika, pono nā emulsifiers high-shear e hōʻoia i ka maikaʻi a me ka paʻa o nā huahana like ʻole.
