In metalworking fluids, foam is a real headache. In order for fluids to function properly, foam must be controlled. Foam causes the following problems: 1. Foam does not allow proper functioning of the lubricating function. 2. In many cases, the foam acts as a layer of insulation and does not allow the cooling function to work well. 3. The foam expands the volume of the liquid significantly. 4. The foam suspends the iron filings and particles, which affects the ability to handle the particles during filtration. 5. The foam makes the chemical odor more volatile and easier to form. 6. Inhalation of foam into the pump Neutralize the machine tool pipeline, will cause great harm.
The foam is generated by the following conditions: 1. The liquid is agitated or flowing. 2. The liquid must contain surfactants or emulsifiers. 3. The flowing liquid must be exposed to the air. 4. Some gas is wrapped.
If possible, engineers will eliminate some of the above factors and control the foam will become easier. Therefore, before an emergency defoamer is added, efforts must be made to propose a complete solution mechanically. In the applications of gun drills and jets, high cooling rates, high pressures, and high flow rates are generally required to facilitate chip breaking. Quickly sweep the swarf away from the cutting area. Nowadays, coolants suitable for high pressures, high flow rates, and high flow rates have been developed for lathes and machining centers. This coolant is optimized for anti-foam and air mixing. You can make full use of the machine and the high pressure cooling system equipped.
