With the advent of the era of Industry 4.0, metal processing enterprises pay more attention to improving the performance and adaptability of machine tools to achieve the goal of reducing costs and increasing efficiency. Although the semi-synthetic metal cutting fluid can improve the processing efficiency, the foam problem also brings troubles to the operation. Therefore, the application of metalworking fluid defoamer is also more and more extensive.
Application of metalworking fluid defoamer
Effects of not treating metalworking fluid foam
It brings hidden dangers to workshop management and safety: the level of metalworking fluid increases, and after overflowing from the liquid tank, it will spread around the machine tool, causing foam everywhere on the floor of the workshop. Therefore, cleaning personnel need to clean it frequently, resulting in slippery ground. , which brings security risks. Moreover, the increase of foam level will also convey false information of high liquid level to the sensor of the machine tool equipment, thereby issuing an alarm, and even stopping the operation of the machine tool equipment, resulting in production accidents of unplanned shutdown, which will have a certain impact on workshop management.
Causes of metalworking fluid foam
As a matter of formulation, it is unrealistic for the machining fluid to have no foam at all. Metalworking fluids combine the excellent lubricity of oil and the excellent cooling properties of water. It is the surfactant that makes the oil and water form a stable and uniform whole, so there must be a tendency to generate foam.
For water quality problems, too low water hardness will increase the foam tendency of cutting fluids. Increasing the hardness can help reduce the foam tendency. At the same time, pay attention to the definition of soft water and hard water. For example, 270PPM water is not considered soft water in China, but it is considered soft water in Europe.
Contaminated working fluid or high defoamer loss. The contamination of machining fluids comes from cleaning agents, cleaning agents used to clean machine tools, and even chemicals used to clean floors, or other cutting fluids with a high tendency to foam. The loss of defoamer is due to long-term use, and no new defoamer is added, so its defoaming effect will gradually weaken.
Use of metalworking fluid defoamer
For the treatment of processing fluid foam, in addition to reducing the easy-foaming components in the processing fluid and adjusting the equipment hardware, it is necessary to add and use a special defoamer for metalworking fluids. In the processing fluid, the defoamer It exhibits good compatibility, durability and rapid defoaming. Therefore, if a little defoamer is added regularly, its defoaming and anti-foaming effect can be maintained within a stable range, which is also conducive to the recycling of metalworking fluids.
