Yuav ua li cas xaiv lub tshuab emulsifying tsim nyog, Lub teb chaws Yelemees imported emulsifying tshuab, muaj emulsifying tshuab, pilot emulsifying tshuab
Emulsifying tshuab plays lub luag haujlwm tseem ceeb hauv cov khoom siv sib xyaw ua ke, tshwj xeeb tshaj yog hauv cov khoom sib xyaw ua kua thiab kua
Kev sib xyaw ua kua, roj-dej emulsification, dispersion thiab homogenization, shear sib tsoo muaj cov ntawv thov tseem ceeb heev.Yog vim li cas
Nws yog hu ua emulsifying tshuab vim nws tuaj yeem ua tiav emulsification.Tsim tom qab ua tiav kev sib xyaw ntawm cov roj thiab dej ob theem nruab nrab
Emulsion tuaj yeem muab faib ua ob lub tshuab: roj hauv dej lossis roj hauv dej.Yuav kom ua tiav emulsification, muaj tsawg kawg yog ob qhov yuav tsum tau ua:
Ib qho yog qhov muaj zog mechanical cutting dispersion effect, theem dej thiab roj theem ntawm cov kua nruab nrab tib lub sij hawm txiav thiab tawg rau me me.
Particles, thiab ces coalesce thaum muaj kev sib nrig sib infiltration mixing, tsim ntawm emulsion.Ob yog txoj cai emulsifier,
Nws ua raws li tus choj nruab nrab ntawm cov roj thiab dej molecules, thiab ua rau cov roj thiab dej los ntawm kev txiav txim ntawm nws cov nqi hluav taws xob thiab lub zog intermolecular.
Lub emulsion yuav ruaj khov rau ntev npaum li peb xav tau.
Tam sim no daim ntawv thov ntawm emulsifying tshuab tsis yog tsuas yog txwv rau "emulsification", vim nws tshwj xeeb shear nkaus,
Pulverized hais nyob rau hauv cov kua cuam tshuam nws thiaj li refined mus rau qhov zoo tagnrho particle loj, thiaj li hais tias cov khoom sib tov tag nrho.
Rau hauv cov kua thiab tsim ib qho kev ncua kev ruaj ntseg, cov txheej txheem no tseem hu ua "dispersion".Thiab ntawm chav kawm nrog emulsification
Raws li nrog dispersant, kev ruaj ntseg ntawm kev ncua tuaj yeem txhim kho los ntawm kev ntxiv cov dispersant.Thaum ib yam khoom khov
Nws tuaj yeem yaj tag nrho los ntawm cov kua los ntawm qee lub sijhawm ntawm kev sib cuag nrog cov kua, tom qab ntawd, tsim los ntawm kev cuam tshuam shear
Cov me me yuav yaj sai dua vim tias lawv qhov chaw tshwj xeeb yog ntau zaus loj dua.
Thaum tib neeg siv rau siab homogenizer (compression, siab ceev tso tawm, dav hlau cuam tshuam) kom tau
Tom qab tau txais cov khoom zoo, "refinement" yog sib npaug rau "homogenization", yog li cov emulsifier zoo rau cov khoom siv.
Cov txheej txheem ntawm homogenization thiab tag nrho sib xyaw tseem hu ua homogenization.Yog li, peb tuaj yeem muab cov emulsifier
Hu ua homogenizer, txhawm rau paub qhov txawv, feem ntau tuaj yeem ua cov yas hauv kev kub ceev lossis siab shear homogenizer, kom cov mis nyuj
Tshuaj tshuab muaj ntau lub npe: siab shear emulsification tshuab, siab shear homogenization tshuab, siab shear dispersion emulsification tshuab, siab
Shear homogeneous emulsifier, siab shear homogeneous dispersion emulsifier, ...
Cov yam ntxwv cuam tshuam rau emulsification
1. Cov khoom siv emulsifying
Tam sim no, muaj peb yam tseem ceeb ntawm emulsifying tshuab: emulsifying tov khoom, colloid zeb thiab homogenizer.Emulsifying tshuab hom thiab cov qauv, kev ua tau zoo thiab qhov loj ntawm emulsion hais (dispersion) thiab qhov zoo ntawm emulsion (stability) muaj kev sib raug zoo.Lub emulsion tsim los ntawm agitating emulsifier muaj cov dispersibility tsis zoo, loj thiab ntxhib hais, tsis zoo stability thiab yooj yim ua paug.Tab sis nws cov khoom siv yog qhov yooj yim, tus nqi pheej yig, tsuav yog koj them sai sai rau cov qauv tsim nyog ntawm lub tshuab, siv kom zoo, tab sis kuj tuaj yeem tsim cov khoom zoo sib xws ntawm cov tshuaj pleev ib ce nrov.Colloid zeb thiab homogenizer yog cov khoom siv emulsifying zoo dua.Nyob rau hauv xyoo tas los no, emulsifying machinery tau ua tau zoo, xws li lub tshuab nqus tsev emulsifying, dispersion thiab stability ntawm emulsion npaj los ntawm nws yog zoo heev.
2, kub
Emulsification kub muaj qhov cuam tshuam zoo rau qhov zoo ntawm emulsification, tab sis tsis muaj kev txwv nruj rau qhov kub.Feem ntau hais lus, thaum lub sij hawm emulsification, qhov kub ntawm cov roj thiab dej theem tuaj yeem tswj tau ntawm 75 ℃ thiab 85 ℃.Qhov no nyob ntawm cov yam ntxwv xws li cov ntsiab lus melting ntawm cov khoom uas muaj cov ntsiab lus siab melting, hom emulsifier thiab solubility ntawm roj theem thiab dej theem.
3. Emulsifying lub sij hawm
Lub sijhawm emulsification muaj qhov cuam tshuam rau qhov zoo ntawm emulsion.Qhov ntev ntawm emulsifying lub sij hawm muaj feem xyuam rau lub ntim piv ntawm cov roj theem thiab dej theem, viscosity ntawm ob theem thiab viscosity ntawm generated emulsion, hom thiab ntau npaum ntawm emulsifier, emulsifying kub, emulsifier hom thiab lwm yam.Nws feem ntau yog txiav txim los ntawm kev paub thiab kev sim.
4, sib tov ceev
Mixing ceev yuav tsum txaus
