Yuav ua li cas kom tau txais roj-dej sib npaug hauv cov kua dej ntawm emulsion tshuab

Yuav ua li cas kom ua tiav cov roj-dej tshuav nyiaj li cas hauv cov kua dej ntawm lub tshuab emulsifying: "roj degree tshuav nyiaj li cas" hauv cov kua emulsifying. Kev txiav cov kua dej npaj los ntawm lub tshuab emulsifying homogenizing tuaj yeem muab faib ua peb pawg raws li nws cov qauv qauv: hom roj ntshiab, emulsifying hom thiab hom hluavtaws tag nrho, uas yog hu ua cov roj txiav, emulsifying hom txiav kua thiab cov khoom siv hluav taws xob tag nrho.

Emulsified cutting fluid can be regarded as emulsified pure oil product, and can be divided into emulsified oil (>0.1um), microemulsion roj (< 0.1="" μ="" m)="" two="" kinds.="" with="" respect="" to="" cutting="" oil="" and="" fully="" synthetic="" cutting="" fluid="" with="" relatively="" simple="" system="" structure,="" the="" composition="" of="" emulsified="" cutting="" fluid="" is="" more="" complex,="" and="" the="" working="" fluid="" is="" o="" w="" system,="" so="" the="" perspective="" of="" examining="" its="" formulation="" structure="" is="" more="">

Yuav ua li cas kom ua tiav cov roj-dej tshuav nyiaj li cas hauv cov kua dej ntawm lub tshuab emulsion, muaj peb lub tshuab sib xyaw uas muaj roj, dej thiab surfactant: emulsion, microemulsion, solubilized micelle thiab rov qab micelle tov (so micelle tov). Cov khoom lag luam feem ntau yog thawj ob hom, thiab ob peb yam khoom siv roj tsawg yog rau hom thib peb.

Cov dej ntsiab lus ntawm cov roj emulsified feem ntau tsawg dua 10 feem pua, thiab cov roj cov ntsiab lus Zui yog siab li 80 feem pua. Cov kua concentrated yog w / O hom, thiab qhov kev thov tuaj yeem ruaj khov yog tias nws muaj HLB tus nqi qis. Cov tsos ntawm emulsified roj diluent feem ntau yog milky dawb thiab tsis ci. Lub cheeb ntawm dispersed theem roj droplet yog kwv yees li ntawm 0.1-10um, thiab lub wavelength ntawm pom lub teeb yog 0.4-0.8um. Yog li ntawd, lub reflection ntawm lub teeb nyob rau hauv lub emulsion yog heev zoo kawg li.

Tsis tas li ntawd, qhov kev txwv qis (txog {{0}}.1um) ntawm qhov loj ntawm - General emulsion roj droplet yog ze heev rau qhov kev daws teeb meem (kwv yees li 0.2um) ntawm lub tshuab tsom iav zoo tib yam.

Lub microemulsion roj-dej cov ntsiab lus tuaj yeem siab li 30-60 feem pua, thiab cov roj cov ntsiab lus feem ntau tsawg dua lossis sib npaug li 30 feem pua. Cov kua concentrated yog O / W hom, cov diluent feem ntau yog cov kua pob tshab, thiab cov roj tee txoj kab uas hla feem ntau yog 0.05-0.1um- Cov dej ntsiab lus ntawm microemulsions nrog roj cov ntsiab lus ntau tshaj 5{ {11}} feem pua ​​​​tseem tuaj yeem qis li 20 feem pua. Cov kua concentrated yog w / O hom, thiab cov diluent yog xiav dawb translucent kua. Nws yog kev hloov pauv emulsion (zoo emulsion) nrog cov roj me me ntawm cov emulsion zoo tib yam thiab microemulsion. Qhov loj me me yog 0.1 ~ 0.4um
