Eliminating foam and inhibiting the appearance of foam is the most fundamental purpose of our use of defoamer. Therefore, the most important thing we need to consider is its defoaming and anti-foaming ability. However, due to the epidemic situation in recent years, the price of chemical raw materials has been constantly changing. As a chemical product, the price of polyether defoamer is also fluctuating. At this time, in order to make profits, some manufacturers reduce the part of raw materials and lure consumers to buy by lowering the price, and the effect also makes consumers no longer trust.

For the method of sample testing, NanHui found a very simple test method to tell you here. Use a dropper to evenly add the same amount of defoamer to the foaming liquid sample, start the stopwatch immediately after adding, and record the foam height at different times in time, and repeat 3 times in parallel for each sample. The average value of the foam height is calculated as the standard for evaluating the performance of the defoamer. The better the foam breaking and foam suppression performance of the foaming agent.

Some friends also have concerns about the polyether defoamer itself, such as its poor effect, incomplete defoaming, insufficient foam suppression time, and secondary foam generation, which will affect the foaming system, etc. Wait. In fact, there is no need to worry about these problems, and the results can be obtained after the samples are tested.

Polyether defoamer has the characteristics of good water solubility and fast dispersion. When added to the foaming system, it can quickly penetrate into the foam, quickly defoaming and long-term foam suppression; it has good chemical stability and will not affect the performance of the product after use. and effect, does not change its basic system.
