Kev kuaj emulsion . Cov emulsion xeem yog ib txoj hauv kev los txiav txim seb puas muaj cov lipids uas siv cov tshuaj ntub dej. Cov txheej txheem yog rau tus qauv raug tshem tawm hauv ethanol, tso cov lipids tam sim no kom yaj (cov lipid tau yaj hauv cawv). Cov kua (cawv nrog cov roj yaj) tom qab ntawd txiav mus rau hauv dej.
Kuj paub, ntsuas emulsion ruaj khov li cas?
Turboscan Classic MA2000 yog qhov ntsuas uas ntsuas qhov ze IR backscatter ntawm dispersions uas yuav siv tau los kwv yees ruaj khov . Kev hloov pauv tom qab tawg thoob qhov piv txwv los ntawm saum toj mus rau hauv qab tuaj yeem yog qhov qhia txog kev sib xyaw ua ke, cream, sedimentation lossis flocculation.
Ib sab saum toj, dab tsi yog creaming ntawm emulsion? Creaming tsis yog qhov tseeb tab sis kev sib cais ntawm cov emulsion rau hauv ob emulsions , ib tug ntawm cov (cov qab zib) yog richer nyob rau hauv lub disperse theem tshaj lwm yam. Creaming yog tus txheej txheem tseem ceeb uas lub disperse theem sib cais los ntawm ib emulsion thiab feem ntau yog qhov ua ntej rau kev sib koom ua ke tiag.
Kuj paub yog, dab tsi yog cov txheej txheem sib txawv ntawm kev npaj emulsions?
Cov txheej txheem feem ntau siv los npaj emulsions tuaj yeem faib ua ob pawg A) Trituration Method Txoj kev no suav nrog cov pos hniav qhuav thiab cov txheej txheem ntub dej. ? Txoj Kev Ua Kom Qhuav Qhuav Hauv Txoj hauv kev no cov roj yog thawj zaug suav nrog cov pos hniav nrog me ntsis ntawm dej los ua tus thawj emulsion.
Yuav ua li cas stabilize emulsion?
Emulsion tuaj yeem yog ruaj khov los ntawm kev ua kom cov repulsion ntawm lub dispersed theem piv txwv li, los ntawm kev ua kom cov electrostatic repulsion (uas yog ntev npaum li cas) los yog steric repulsion (short range).

Qhov sib txawv ntawm kev ntsuas t rau kev kuaj ywj pheej thiab t kuaj rau cov piv txwv nyob li cas?
Kev kuaj tus kheej t-test sib piv ob pawg neeg ywj pheej ntawm kev soj ntsuam lossis ntsuas ntawm ib tus yam ntxwv. Kev kuaj tus kheej t-test yog qhov nruab nrab ntawm cov ncauj lus sib piv rau cov piv txwv t-test, uas yog siv thaum txoj kev tshawb fawb cuam tshuam nrog kev ntsuas dua (piv txwv li, pretest vs
