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, which 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. However, 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 low dosage, 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 oil and cutting fluid. To
3. Good heat resistance, chemical stability, non-corrosive, non-toxic, no adverse side effects, non-flammable, non-explosive. To
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 chemical cutting fluid defoamer developed by Nanhui Antifoaming Agent Factory is a highly efficient concentrated liquid. It can be diluted with 20 times of water when used. The special compound cutting fluid defoamer can be directly added to the dilute solution to achieve good defoaming performance. Inconvenient, 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.
