The foam problem has been plaguing all aspects of the application of metal working fluids. To solve the foam problem is the key to the success of the on-site application of metal working fluids. For different products of different systems, the foam problem is not the same, and it needs to be solved.
Fully synthetic product
The whole synthetic product adopts the oil-free formula system, and the additives used are also mainly selected without emulsifying ability. The use of special water-based polyether, air release and foam properties are better, foam problems are relatively rare.
However, due to the increasingly harsh processing conditions in recent years, as well as the process, tool grinding wheel update, put forward higher requirements for the settling capacity of the processing fluid, especially in the process of centerless grinding, the cleaning capacity of the cutting fluid is also very important, it is very important to choose the right single agent, such as phosphate, both low foam and wetting, rust and other energy absorption, excellent use effect.
Semi-synthetic product
Semi-synthetic products are widely used in the market, and there are many design and processing fields, and the foam problem still needs to be designed according to the application and the preceding and following processes.
The defoaming of semi-synthetic cutting fluid depends on the joint action of defoaming agent and defoaming agent. Traditional defoamer is time-effective, while some specially designed calcium soap will also have anti-foaming effect, the hardness of water is very important,
For customers with hard water quality, the main concern is the resistance to hard water performance of the product, and the foam performance is second, but for customers with soft water quality, the foam problem is the top priority, and additional water hardness regulator may be required.
Therefore, how to select products or design products according to the customer's working conditions and the process before and after the water quality is a very important work. According to the specific process conditions and process parameters, the recommendation of suitable products is an important determining factor for the successful commercialization of products and the completion of sales.
Knock on the blackboard!
In most cases, once a bubble problem occurs, it may result in customer complaints. In the performance of the bubble, it is very critical to determine the cause of the bubble through a reasonable analysis of the problem, which needs to be investigated by the following factors.
1. Site management
Replenishment rule, use concentration, oil concentration, alkali concentration, miscellaneous oil content, external pollution.
2. Equipment factor
Pressure of the liquid supply tank, volume, cleaning, whether the pump is vacuumed, the use temperature of the processing fluid, etc.
3. Use of defoamer
Whether the defoamer is used, whether it contains silicon, whether there is a filter device, whether the back channel is cleaned, whether there is a heat treatment process, etc. Defoamer must not be added randomly, reasonable use of defoamer in order to best effect, reduce production costs, improve production efficiency.
Semi-synthetic products to shoulder cooling, lubrication, cleaning, metal protection and other multi-faceted functions, but also to meet the customer's environmental protection, user-friendly low consumption and long life requirements. To meet customer needs.
When designing the formula, we need to consider the balance between the various properties of the product, to meet the needs of most customers as much as possible, and it is particularly important to choose high-quality additives.
