There are many reason that foam caused by the production of concrete construction, such as large bubbles during stirring, surfactants containing polycarboxylate superplasticizers are aggregated into large bubbles and water reducing agents by vibrating action. Self-quality, free water that is not in... read more
Then when defoamer should be diluted? Based on above we talked about the shortcomings of using water to dilute defoamer, then is it not possible to dilute defoamer with water? No!! In some cases, it can be directly dilute with water. If you are an end customer and use it on the production, you can ... read more
The method of dilute defoamer: Prepare alkali swelling thickener Preparation of thickened water: Add alkali-saturated thickener into water, adjust the pH of the thickener aqueous solution to 6.8-7.2 by 10% NaoH solution (Generally speaking, the amount of NaOH solution can be added according to 40... read more
Physical defoaming Spraying water, high-speed spraying water or water droplets can break up the bubbles floating on the water surface, which can reduce the foam. Although it can not be defoamed at all, it is a simple and common physical method. Although the foam is reduced, once it stops, The foam ... read more
