Why metalworking fluids are easy to bubble and how to solve them

Causes of blistering of metalworking fluids:

1.If the tank is too small and the foam does not have time to dissipate, there is often a risk of foam benefits.

2.Other additives are added to create a chemical reaction that causes foaming overflow.

3.In industrial production, machinery runs at high speeds, shakes, and gas ingress to cause foam to occur.

4.The power of the equipment is not suitable, which leads to problems such as injection pressure and cutting fluid temperature, which causes foam to occur. The physical defoaming equipment independently developed by Fenggu Energy Saving Technology replaces manual addition, which is pure and safe, non-efficient, automatic operation, and has a strong defoaming effect, which solves the problems of manual timing delivery, potential media pollution, and large long-term purchase costs.

When the metal processing plant uses cutting fluid, because it contains a large amount of surfactant, and the surfactant has strong foaming, when the flow rate in the metal processing process is too fast, it will produce strong foam, these foams will not be eliminated in time will lead to the loss of cutting fluid, thereby affecting the quality of processing, then the best way to solve the foam is to add metal processing defoamer.

Metalworking fluids are mainly metalworking liquids, which mainly play the role of lubrication and cooling, as well as anti-rust cleaning and other functions. General metalworking fluids include cutting fluids, cutting oils, emulsions, grinding fluids, anti-rust oils, cleaning agents, thickeners, and so on. There are many problems that often arise when using metalworking fluids for metalworking, among which the more common is the foaming problem, and the foam of metalworking fluids can easily affect the quality of processing.

What are the possible causes of cutting fluid foaming? The level of the process fluid is too low; The flow rate of the cutting fluid is too fast, and the bubbles do not have time to overflow, and they accumulate more and more, resulting in a large amount of foam; There are too many right angles in the design of the sink during the use of the processing fluid; The processing fluid contains a large surfactant dose; The water is too soft, resulting in excessive foam; The constant change in air temperature and pressure is also responsible for the formation of bubbles.

How to solve the foaming of cutting fluid? In the centralized cooling system, the pipelines are graded in series, and the pressure of the pipelines near the cooling box should be lower; Ensure that the liquid level of the cutting fluid is not too low, check the liquid level height in time, and add cutting fluid in time; Control the flow rate of cutting fluid not too fast; When designing a sink, you should pay attention to the right angle of the sink not too much; When using cutting fluid, care should be taken that the angle of the cutting fluid nozzle is not too straight. Of course, I think the best way to do this is to add a metalworking fluid defoamer.

Metalworking fluids are too of its composition, and for such specialized questions as these, you should go to an expert. "Runli Chemical" is an expert in metal processing, and also provides free solutions, which are recommended to you and hope to help you.

A lot of surfactants will be added to the metalworking fluid to achieve the effect of lubrication, flushing and rust prevention, but these surfactants are easy to cause blistering, and there are some other reasons that will also cause the metalworking fluid to blister: excessive stirring in production, unreasonable design of the metalworking fluid system, unreasonable layout of the reflux pipe and liquid tank, too fast flow rate of the metalworking fluid, and no time for bubbles to overflow will also cause the metalworking fluid to bubble. It is possible to add a metal pat processing fluid defoamer for defoaming.

Common problems in the use of cutting fluid: the main reason is that the cutting fluid contains a large number of bacteria, and the bacteria in the air enter the cutting fluid and the workpiece process, causing the infection of the cutting fluid. The corresponding inhibition measures are the use of high-quality, stable cutting fluids, keeping the cutting fluids clean and using biocides frequently.

Cutting fluid corrosion: The main causes are the low proportion of concentrated cutting fluid, the pH value of the cutting fluid is too high or too low, and the contact of dissimilar metal materials, the number of bacteria in the cutting fluid is too high and the humidity of the working environment is too high. The cutting fluid should be configured with pure water, and the proportion of cutting fluid should be used according to the recommended value in the specification of the cutting fluid used; Use anti-rust fluids when needed; Avoid contamination of cutting fluids and avoid contact with dissimilar materials.

Foam of cutting fluid: the main reasons are that the liquid level of cutting fluid is too low, the flow rate of cutting fluid is too fast, the nozzle angle of cutting fluid is too straight, and stirring to prepare cutting fluid. When using, attention should be paid to ensure the liquid level height of the cutting fluid and add cutting fluid in time; Control the flow rate of cutting fluid not too fast; Pay attention to the angle of the cutting fluid nozzle is not too straight; When dispensing emulsions, avoid vigorous stirring and air stirring.

Allergies: The main reason may be that the pH value is too high, the composition of the cutting fluid is too high, or the concentrate is too high. The operator should pay attention to avoid direct contact with the cutting fluid, use the fungicide according to the dosage in the instructions, and the proportion of concentrated liquid in the cutting fluid must be used in accordance with the recommended value of the cutting fluid.
