By using the customer's filtrate or other process liquids, we can evaluate different defoamer solutions without having to make large and expensive full-scale experiments.
Process chemistry and wood raw material vary, which is why a defoamer that works excellently in one system may be ineffective in another. Each system must therefore be optimized based on its own conditions.
The mills often have a supplier of defoamers and prefer to stick to it because a replacement requires extensive analysis and testing. Reasons for changing may be the possibility of a more efficient or cheaper product, that you have foam problems that the current product cannot handle or that the product requires too large and thus expensive dosage levels.
By analyzing the current process filters, it is possible to determine the cause of a complicated foaming problem. It is also possible to evaluate different defoamers as well as to study where the silicone in the defoamers goes. It must not stop and clump together with resin and other contaminants, which can cause production problems both in paper mills and in printing works.
