Correct use method of emulsion

First of all, we should choose appropriate drawing oil according to the different requirements of wire drawing process, each monarch number products of the formulation design features are different. On the premise of the comprehensive properties of equilibrium, certain aspects will be focus on the choice of the principle of considering two aspects of process and oil, i.e. the process to consider: the drawing machine, a liquid supply system, line types, size, surface condition of line; consider characteristics: oil lubrication, anti oxygen, clean, use concentration, life, emulsion stability, the use of cost etc..
Because the emulsion is a so-called "unstable system", master the correct application method of emulsion is very important. The use of special attention to the following aspects:
(1) system cleaning: wire drawing machine and its centralized purification liquid supply system can be achieved by using appropriate cleaning agents. Especially pay attention to the removal of the biofilm on the wall of the tank. If the system is dirty or have been biological bacteria pollution, recommend the use of alkaline pretreatment of alkaline joined the bubble will appear, and should therefore be to two to three steps to add.
(2) with liquid water is best to use soft water or deionized water with liquid as parts of emulsion is water. Hard ingredients in water chemical reaction will occur and the wire drawing oil emulsifier, emulsifier and reduced the number of the oil-water separation. Therefore, the stability of water hardness on the emulsion of great influence and reaction of the salt will be attached to the copper surface. Effects of subsequent processing, therefore, formulated for emulsion paint for pull filaments or line, you must use the deionized water. Chlorine content in water such as more than 100X10, should not be used for chlorine, bacteria content in fresh water corrosion control strong also nots allow to ignore, should ensure that no bacteria system. Content of microbe pollution in emulsion to 10 / ml, the conductivity distribution of liquid water should be below 800t, S / era.
(3) reason for using temperature operating temperature control, one is to control the water evaporation, avoid the cumulative increase hardness of generating solid salt; two is to ensure the lubrication, the temperature is too low lubricity nakedness salt; concentrated liquid supply system should normally be used heat exchanger. Recommend the use of a temperature of 35 DEG C to 45. Between C.
