Yuav ua li cas kom ua tiav cov roj sib npaug dej siv lub emulsifier

Raws li rau "roj tshuav" nyob rau hauv lub txiav kua ntawm Wuxi Jiangke emulsion tshuab, txiav kua npaj los ntawm lub emulsification homogenizer yuav muab faib ua peb pawg: hom roj ntshiab, emulsified hom thiab tag nrho cov khoom hluavtaws raws li nws cov qauv qauv, uas. yog feem hu ua tej kua, emulsified tej kua thiab tag nrho cov hluavtaws txiav kua.
500L lifting external circulation homogenizing emulsification homogenizer. Emulsifying machine cutting fluid can be regarded as emulsified pure oil products, which can be divided into emulsified oil (>0.1um) thiab microemulsified roj (<0.1 um) based on the size of emulsified oil droplets cut by the emulsification homogenizer μ m) Two types. With respect to cutting fluid and synthetic cutting fluid with simple system structure, the composition of emulsified cutting fluid products is more complex, and the working fluid is the O/W system, so the perspective of examining its formula structure is also more rich.

Txog tam sim no, muaj peb hom kev sib xyaw ua ke uas muaj roj, dej, thiab surfactants: emulsions, microemulsions, yaj micelles, thiab rov qab micelle daws (so micelle daws, feem ntau ntawm cov khoom muaj nyob rau thawj ob hom, thiab ob peb yam tsawg. Cov khoom siv roj yog hom thib peb).
Cov dej hauv cov roj emulsified feem ntau tsawg dua 10 feem pua, thiab cov roj cov ntsiab lus tuaj yeem ncav cuag li 80 feem pua. Qhov kev daws teeb meem yog hom W / O, thiab lub kaw lus yuav tsum muaj tus nqi qis dua HLB thiaj li yuav ruaj khov. Cov tsos ntawm emulsified roj diluents feem ntau yog milky dawb thiab tsis haum rau cov xim ci. Lub cheeb ntawm dispersed theem roj droplets yog roughly nyob rau hauv qhov ntau ntawm 0.1 ~ 10um, thiab pom lub teeb wavelength yog 0.4 ~ 0.8um. Yog li ntawd, lub reflection ntawm lub teeb nyob rau hauv lub emulsion yog kuj tseem ceeb.
Tsis tas li ntawd, qhov qis qis ntawm emulsion droplet loj (txog {{0}}}.1um) zoo ib yam li qhov kev daws teeb meem ntawm lub tshuab tsom iav tsis tu ncua (txog 0.2um).
Cov dej hauv microemulsion tuaj yeem ncav cuag li {{0}} feem pua, thiab cov roj cov ntsiab lus feem ntau tsawg dua lossis sib npaug li 30 feem pua. Nws cov concentrated tov yog hom O / W, thiab cov diluent feem ntau yog cov kua pob tshab. Txoj kab uas hla ntawm cov roj tee feem ntau yog 0.05-0.1um- Cov dej ntsiab lus ntawm qee cov microemulsions nrog cov roj cov ntsiab lus txog li 50 feem pua ​​lossis ntau dua tuaj yeem qis li 20 feem pua. Cov tshuaj concentrated yog W / O hom, thiab cov diluent yog xiav dawb translucent kua. Nws yog ib qho kev hloov pauv hauv lub xeev emulsion (me me emulsion) uas nws cov roj poob loj yog nruab nrab ntawm cov emulsion thiab microemulsion, thiab qhov poob loj yog 0.1 ~ 0.4um.
