txoj moo

Hauv cov xim pleev xim rau cov dej, emulsions, dispersants, cov kuab tshuaj uas tsis txaus, koj tuaj yeem xaiv cov neeg sawv cev ntub dej.

Thov nco ntsoov tias qhov kev xaiv zoo ntawm substrate wearting tus neeg sawv cev ntawm cov khoom siv dej ntawm Watered Waterpuam, yog li muaj ntau hom neeg tiv thaiv plua plav yog cov neeg sawv cev.

Cov hom ntawm cov chaw ntub dej ntub yog: anionic surfactants, kev ua haujlwm polysiliacs, thiab lwm yam kev sib tw ua haujlwm zoo (tshwj xeeb tshaj yog rau kev ua haujlwm siab- Xws li cov xim pleev xim), feem ntau soluble hauv dej, qis npuas thiab tsis ruaj npuas, thiab yuav tsis ua kom muaj teeb meem roosating thiab cov nplaum poob.

Feem ntau siv substrate ntub cov chaw ntub dej yog cov tshuaj tiv thaiv kab mob ethylene-nonymyilaimon

Txoj kev tsis meej pem, cuam tshuam los ntawm kev tshaj tawm, yog tias kev txo qis nro nyob ib leeg ib leeg yog qhov tseem ceeb tshaj plaws, thiab cov cuab yeej no tseem muaj feem xyuam rau kev sib raug zoo ntawm cov kab ke thiab cov qauv nro.

Qhov kis tau muaj peev xwm ntawm tus neeg ntub dej yuav txiav txim siab los ntawm kev ntsuas thaj chaw ntawm cov khoom siv ntub dej (0.05 ml) ntawm cov khoom siv ntub dej ntawm cov xim ntub dej rau cov xim. Cov neeg sawv cev ntub dej.

Feem ntau, tus nqi ntawm cov npoo zoo li qub tsis tuaj yeem sib haum ntawm kev tsim kho, thiab cov xim muaj zog nyob rau hauv kev tsim kho, thiab qis dua cov xim muaj zog nyob rau lub sijhawm no, qhov muaj txiaj ntsig zoo rau ntub dej. Fluorocarbon surfactants feem ntau txo cov npoo zoo li qub, uas yog ib qho ntawm cov laj thawj yog vim li cas cov ntawv thov fluorocarbon surfactants yog nyob deb tsawg dua li ntawm silicones.

Kev xaiv cov kuab tshuaj uas tsim nyog kuj tuaj yeem muaj cov nyhuv ntub dej ntub dej. Vim tias cov kuab tshuaj yog sib haum nrog lub kaw lus, cov txheej txheem muaj zog ntawm cov nro muaj tsawg.

Saib xyuas tshwj xeeb: yog tias lub substrate Wetting tus neeg sawv cev tsis raug xaiv kom zoo, nws yuav tsim ib txheej molecular ntawm cov txheej txheej av tsis zoo, uas yuav cuam tshuam rau cov adhesion.

Ntau cov neeg sawv cev ntub dej sib txawv tuaj yeem sib xyaw los daws cov nyom av ntub.
