Regular maintenancemanagement of emulsion

Some of the properties of emulsion is very important to use effect, based on this reason, recommend regular maintenance and management of the following indicators: concentration, pH value, conductivity, biological control. The specific scope of control data and drawing oil related products, manufacturers recommended maintenance related reference.
(1) concentration concentration is determined according to the operation type and oil characteristics, need to be checked regularly (every best), concentration has two kinds of detection methods: to maintain the concentration determination of refractometer (Simplified), separation of emulsion method.
(2) the value of pH in pH control range: cruise. Because the emulsion direct contact with air, the air containing oxygen, COz, the emulsion due to oxidation and acidification process, the pH value will decline. There are bacteria, pH will fall. If the pH value is too low, the emulsion will become unstable, demulsification, even drawing die wear broken problem occurred. Usually because of COz caused by pH value decreased by adding new liquid to compensate. Reasons for the decline in the value of pH is not sure, can be used to adjust the pH value regulator.
(3) the conductivity of emulsion can not be permanent maintain unchanged. With the groove, carbonate emulsion evaporation, salt residues in copper wire, and the addition of hard water, salt content in the emulsion will increase with time. Only because of evaporation loss caused by increased salt content will also make conductivity increase. And the ancient salt emulsion instability on the amount, so by measuring the conductivity, can determine its condition, decide whether it should change liquid.
(4) the biological balance biological control emulsion must be controlled, can prolong the service life of emulsion. In addition to the total bacterial content, should also find out whether the emulsion containing anaerobic desulfurization seedlings, they will be attached to the copper wire. At the same time, is also very important for control of fungi, yeasts and molds, the seedling may be composed of air, water, environment residues and the accident of pollution sources, into the system. Fungi, yeasts and molds can block the pipeline, resulting in wire drawing breaking, wire drawing die, a guide wheel wear, Nymphoides dyeing machine. Determination of biological fungi or bacteria can be determined by measuring the area of general fast: the total bacterial content, desulfurization bacteria and fungi, yeast and mold.
According to test results, such as bacteria pollution, measures should be taken immediately, the use of specific fungicides.
