When using textile defoamers, many manufacturers will encounter problems such as poor defoamer performance, incorrect usage methods, and incorrect dosage. We have compiled some common problems to share with you.

Problem 1: The textile defoamer is turbid. First of all, we need to know that when using defoamer, it does not exist in a dissolved state in the system but is usually suspended in the system. Therefore, the selected hydrophobic particles, silicone oil, and hydrophobic particles are The dosage and color are crucial, but as long as the defoaming effect is good and the foam suppression time is long, there is no big problem if the corresponding system is suitable.

Problem 2: Foam suppression time of textile defoamer. If the textile defoamer used is of the silicone type, then its silicone oil properties determine its foam suppression time, and the content of silicone oil determines the use of the defoamer in the system. The length of time. In addition, the particle size of the textile defoamer also determines the filtration resistance of the defoamer. If the particle size is too large or the defoamer is not stirred sufficiently, it may cause the defoamer to be filtered out, which will affect the performance of the defoamer. Defoaming and anti-foaming properties are affected.

Problem 3: The textile defoaming agent fails. High temperatures, strong alkalis, etc. often occur in the textile environment. Therefore, if the high temperature resistance, acid resistance, and alkali resistance of the defoaming agent are not high, it will cause the defoaming agent to fail; if some chemicals in the system cause the defoaming agent to dissolve in it, it will not have a defoaming effect.

Problem 4: Selection of types of textile defoaming agents. Foam is mostly generated by the action of external forces. The surface-active substances contained in the solution form bubbles and float at the interface between the solution and the air. The function of the defoaming agent is to reduce surface tension and eliminate foaming substances during processing.
