After purchasing an antifoaming agent, its performance must be tested; it may only be put into service once it has passed the tests. Today, we will share three testing methods.
Purchase Defoamer Subsequently, its performance must be tested, and it may only be put into service upon passing the inspection. Today, we will share three testing methods.
I. Mixing Test: Introduce air into the… Defoamer In the defoaming system, after stirring, the sample is transferred to a measuring flask for weighing, and the defoaming performance is assessed by comparing the weights.
II. Flow Coating Test: Place the polyester film on a frame inclined at a specified angle, pour the defoaming solution into the defoaming system, stir uniformly, and then apply it onto the polyester film; observe whether any bubbles appear on the surface.
3. Roller Coating Test: Use test cardboard to assess surface defects on the test panel and check for bubbles containing light spots.
The above are the three main methods for evaluating the performance of defoamers; we hope this information proves useful.
