Metal fully synthetic cutting fluid defoamer solution

Customer type

1. Customer information: Philippine Hill Metal (surface material surface) Co., Ltd., chemically synthesized cutting fluid is a new type of water-based cutting fluid, which is compounded by various additives, with stable performance, long service life, and low The advantages of pollution and other advantages are the current research direction of cutting fluids. In the research and development of Nanhui Antifoaming Agent Factory, it is found that its disadvantage is that it is easy to foam during use, which directly affects its lubrication and cooling effects.

2. Sample information: fully synthetic cutting fluid

3. Customer requirements: It must be defoamed and anti-foaming, which can inhibit the generation of foam. Adding to the original liquid will not affect the transparency of the cutting fluid itself.

Principle and analysis of defoaming

1. Analysis of the cause of blistering:

Chemical synthetic cutting fluid is a new type of water-based cutting fluid. It is compounded by various additives. It has the advantages of stable performance, long service life, and low pollution. It is the current research direction of cutting fluid. In the research and development of Nanhui defoaming agent factory, it was found that its shortcoming is that it is easy to foam during use, which directly affects its lubrication and cooling effects, but the general cutting fluid defoaming agent can not meet the requirements.

2. The hazards of blistering:

Its disadvantage is that it is easy to foam during use, which directly affects its lubrication and cooling effects.

3. Analysis of the program of fully synthetic cutting fluid defoamer

Cutting fluid defoamer is used in metal processing, cutting fluid, microemulsion, high water content hydraulic fluid, glycol hydraulic fluid, solvent cleaning, acid-base water-based cleaning agent, coolant, grinding (oil) fluid, wire cutting fluid , Automatic assembly line cleaning machine, large-scale washing machine, lubricating (oil) fluid, saponified oil, electric spark working fluid, drilling fluid, fine grinding fluid, etching fluid, electrolyte line cutting fluid, alkaline extraction process defoaming, dehydration Defoaming and suppressing foam in occasions such as agents.

Fully synthetic cutting fluid characteristics:

1. It has strong defoaming and anti-foaming power, with a small amount, and does not affect the basic properties of the foaming system. To

2. It has good diffusibility and permeability, and can be completely compatible with oils and cutting fluids.

3. Good heat resistance, chemical stability, non-corrosive, non-toxic, no adverse side effects, non-flammable, non-explosive.

4. It can be used in acid, alkali, salt, electrolyte and hard water.

5. Its performance is comparable to imported products, and the price is more obvious.

Solution to the foaming of cutting fluid

The chemically synthesized cutting fluid developed by Nanhui Antifoaming Agent Factory is a highly efficient concentrated fluid. It is diluted with 20 times of water when used. The special compound type cutting fluid defoamer can be directly added to the dilute solution to achieve good defoaming performance, but it is not convenient to use , It should be added to the concentrate. The compound defoaming agent was prepared according to the optimal ratio obtained by the above orthogonal experiment, and the addition amount and the addition process experiment were carried out. Experiments show that this composite defoamer is best added during the cutting fluid preparation process, and the addition amount is less than 1%. It is added in two steps. The first step is added in the middle of the synthesis of the cutting fluid, which can make the defoamer react with the stock solution and inhibit the foam during the reaction, and the second step is added in the late stage of the reaction. Adding the defoamer in stages can better exert its effectiveness and at the same time reduce the amount added.

Because lubricating oil is similar to transmission oil, hydraulic oil, metal cutting fluid, drawing oil, emulsified oil, cooling oil, grinding oil and other foaming reasons, the results of this experiment are applicable.
