Tips for Printing and Dyeing


Many users will think that the thicker the silicone defoamer, the higher the concentration of defoamer, the better the effect. But is that really the case?


In fact, there is no relationship between the viscosity and concentration of silicone defoamers. High concentration of silicone defoamers may have very low viscosity, while high viscosity of silicone defoamers may have very low concentration. Therefore, it is impossible to judge the quality of silicone defoamers solely from the viscosity, otherwise it is easy to draw wrong conclusions, thus affecting the use effect.

According to the analysis of technicians, the viscosity of organosilicon defoamer is related to the viscosity of the active substance itself, the type of thickening agent, the content of defoamer and the production process. In the process of using organosilicon defoamer, it is necessary to select and evaluate according to the specific industry and application environment. Therefore, the thicker the organosilicon defoamer is, the better the effect of using organosilicon defoamer is not necessarily. As a result, the dispersing speed of defoamer in foaming medium becomes slower, which ultimately affects the defoaming effect.


These are the explanations for whether the organosilicon defoamer is more viscous and better. I hope it will be helpful to everyone.


In addition, many dyeing factory masters or factory directors pay more attention to the appearance and concentration of dyeing and chemical additives. Most of them think that the higher the viscosity, the higher the content. In fact, this view is very wrong. The content is not necessarily proportional to the viscosity. Excellent dyeing and chemical additives are made in the direction of low viscosity, colorless and high content.
