Many additives are used in industrial production, emulsified oil is no exception, it is composed of base oil and additives, as long as the appropriate ratio, emulsified oil can be more stable. Therefore, do not ignore the problem of foam, foam will destroy the production efficiency of emulsified oil, affect the use effect. But there are emulsified oil defoamer, emulsified oil does not seem to love foam.
Why does emulsified oil bubble? Crude oil itself has foaming mechanism, additives contain surfactants, in the production process, foam is unknown, imperceptibly formed. In addition, emulsified oil in the process of metal processing, if the residual metal processing liquid or chemical or chemical additives in the equipment, will react with each other, or in the processing environment quickly mixed, high shear. Mechanical equipment, easy to bubble.
Analyze the cause of foaming, if some students do not pay attention to, may wish to see the harm of foaming, in another way of thinking:
1. Bubbles will affect the performance of emulsified oil and reduce the effect of rust prevention, cooling and lubrication.
2. Increase the difficulty of operation, slow down the production schedule and increase the cost. Foam will affect the output of emulsified oil.
3. Foam produced by emulsion can cause overflow, pollute the surrounding environment and waste raw materials.
4. Foaming will increase the gas-liquid contact of the emulsion, promote oxidation, produce flotation, make the composition uneven mixing, and make the product metamorphic. Made from special modified polyether and fluorine raw materials. In addition:
5. Under the condition that wear-resistant hydraulic oil has basic performance, wear-resistant hydraulic oil has strong defoaming ability, long bubble suppression time and less consumption.
6, without affecting the emulsified oil itself performance, good dispersion and permeability and liquid fully compatible.
7, no precipitation, acid and alkali resistance, no float, no precipitation, no oil float.
8, stable defoaming defoaming stable defoaming, such as high temperature, strong acid, strong alkali, high shear force, high pressure, etc.
