Metalworking fluids can be divided into cutting fluids, grinding fluids, stamping fluids, drilling fluids, milling fluids, etc. according to different processing techniques and requirements. Different types of metalworking fluids have different characteristics and scope of application. Defoamers need to be selected and used according to specific conditions. Nanhui metalworking fluid defoamer is a general-purpose defoamer with fast defoaming speed and long antifoaming time. Long-term, high temperature resistance, can be applied to different types of liquids.
Main principle:
During the production and use of metalworking fluids, a large number of bubbles are generated due to friction or stirring, and a small amount of bubbles cannot be broken due to the effect of surface tension and viscosity, so foams will be generated. The surfactant structure in the metalworking fluid defoamer is specially designed, which can make The bubbles break down into smaller foams and rise rapidly upward to burst.
Main application fields:
Metal processing often uses a variety of different metal processing fluids to assist in metal cutting, grinding, stamping, drilling, milling, etc., and it is easy to generate a large amount of foam. Metal processing fluid defoamers are used in this case It is very practical and can effectively eliminate foam in metalworking fluids, prolong the service life of metalworking fluids, and improve production efficiency and quality.
Precautions:
1. If the addition does not work, do not blindly increase the defoamer into the raw material, which may be caused by another factor, such as viscosity, water balance or pH value, etc.
2. The defoamer has a complex chemical composition, and the dosage must not be exceeded, otherwise it may have a negative impact on the processing fluid.
3. Before adding, the diluent should be prepared and fully stirred evenly, so that the defoamer can be easily dissolved and the expected effect can be achieved.
