Choose organosilicon defoamer must pay attention to these!

With the increasing diversification of industrial production, there are more and more demands in the process of production. In order to meet the normal needs and demands of industrial production process, defoamers are often used during production. At present, the most widely used defoamers are organosilicon defoamers.


But as you all know, nowadays there are not only many manufacturers of defoamers, but also many kinds of products. Different products use different methods and effects, so it is particularly important to choose a suitable defoamer. Take silicone defoamer as an example, let the editorial of China Paper Industry Network tell you what to pay attention to.






1. Defoamer is a sub-industry, there is no omnipotent defoamer. So we should choose the most suitable defoamer for our own industry.






2, when choosing defoamer, we should pay attention to choosing to eliminate harmful foam in the production system, but it can not produce bad effects on the material in the production system. This is when we choose to buy it, we need to consider it clearly.






3. The defoamers used in industry are different from those used in food and medicine. The defoamers used in food and medicine need to be certified by the state while those used in industry are not so strict.






4. The defoamer is divided into water-borne defoamer and oil-borne defoamer. When choosing the defoamer, we need to know which defoamer is suitable for our production system.






5. Once the types of defoamers are determined, a product with stable quality can be selected among these defoamers, so as not to cause serious losses due to production problems.






6. There are many manufacturers of defoamers, and the market of defoamers is chaotic. We must make a decision after trial.






7. Defoamers are not necessarily the best, but they are often inexpensive and certainly not too good. The so-called "one penny, one delivery" requires cost and profit. Too cheap products are bound to be discounted in terms of content and effect.






8. Distinguishing the production process of one's own industry is the existence of high temperature, strong acidity, strong alkalinity, or high shear stress and other environments, because these may destroy the defoamer and affect its defoaming effect. If there are above problems, special defoamers need to be selected, so the price will be relatively expensive.
