What is the importance of concentration control in emulsions, what are disadvantages of operating under low or high concentrations?
There are ideal applications concentrations of emulsions for the operations they are used and maximum performance can be obtained within these limits. Going beyond these limits may cause problems. Thus, concentration should be checked up daily. The easiest way of concentration check-up is using the portable refractometer. If concentration is high; • Sticky deposits form on the item surface and workbench. • There is smoke in emulsifying zone. • Irritation may occur on operator’s hands (Especially with synthetic products). If concentration is low; • Oxidation problems may be seen on items and workbench. • Due to decrease of lubrication, sharpening period of cutting equipments shorten, intended surface smoothness quality cannot be obtained. • Emulsion is less protective against bacteria propagation.
