The Reason Of Metal Cutting Fluid Bubble Easily And The Harm Of Foam

Cutting liquid dilution ratio is low, such cutting liquid concentration is high; If the cutting fluid spray liquid flow rate is too fast, the water pressure is larger; The soft water contains more soluble calcium and magnesium compounds, and the cutting fluid will react with them. All these factors will lead to a large number of bubbles in the cutting fluid; Cutting liquid level is too low, easy to mix with air, dissolved air will be separated out in large numbers, the formation of bubbles to produce holes. The production of cutting fluid foam will affect the use effect of cutting fluid, making the function of cutting fluid greatly reduced; Make equipment faster oxidation and rust, reduce the service life of equipment; Excessive foam will sputter into the skin of the operator during the spraying process, affecting the health of the operator; Lead to discharge cutting fluid sewage monitoring is not up to standard, consumption of manpower and financial resources. At this time, the use of metal cutting fluid defoaming agent, the following for you to explain its importance in detail.

Metal cutting fluid defoaming agent is mainly divided into emulsion oil cutting fluid defoaming agent, semi-synthetic cutting fluid defoaming agent and fully synthetic cutting fluid defoaming agent. These three kinds of defoaming agents have their own characteristics:

Emulsified oil cutting fluid defoaming agent: defoaming agent speed, can improve the brightness of parts, prolong the service life of the tool. Good dispersion, permeability, and oil products. The cutting fluid is well compatible.

Semi-synthetic cutting fluid defoamer: has strong high temperature resistance, strong acid and alkali resistance, can be used in high temperature environment and strong acid and alkali environment foaming system.

Fully synthetic cutting fluid defoaming agent: This defoaming agent is a compound type defoaming agent, easy to disperse in water, resistant to a variety of harsh environment, has a good defoaming, defoaming effect.

Cutting fluid defoaming agent in the use of environmental requirements is not high, in a variety of normal and harsh environment can be used normally, will not affect the effect of defoaming, bubble suppression. The use method is generally added directly to the cutting fluid, when the cutting fluid is used, the foam can be obviously felt less. In terms of dosage, it is generally between 1/1000 and 5/1000, and the actual dosage needs to be determined by sample testing.
