How to Determine Efficacy of anti-foaming agent (such as brushing, spraying, dipping, printing, etc.), can be selected according to different test methods different construction conditions. 1, stirring the acid test for our users, defoamers, easiest test method is stirring test. Under certain conditions, a turbine blade with air has infiltrated defoamer coating system under test. After stirring, the material was poured into the measuring flask immediately with graduated markings, and weighed by difference between the weight of the defoamer comparison, the system determines the amount of air infiltration, so infer antifoam effect. This test also shows how the amount of air in the form of spherical bubbles contained in the system. Another test method is used to detect the number of macro bubbles. Under certain conditions the concrete defoamers, air infiltration to the system, and then measure the height of the cylinder by the same weight of material, defoamers, defoamer evaluation results. The method can guide us in the selection of the mixing container capacity ratio practical work. Many defoamers front will lead to the film surface defects, such as craters, etc., it is the same problem with foam polyether defoamers, all of us want to see the ink producers, which can only be used through volume a large number and wide range to carry out experiments and tests. First, the overall performance: This product is imported into the silicone-modified silicone oil and grease, dispersants, emulsifiers as main components, the use of advanced production technology from the new complex of highly concentrated, highly efficient anti-foaming agent. Appearance: milky white flowable liquid, PH value: 6-8, water and oil separation defoamer, stability (3000 rpm / 20 minutes): no delamination, silicone defoamer, specific gravity: 0.98-1, ionic character: nonionic, Dispersion: by mixing can be better dispersed in the water. This product is designed for the petrochemical process design defoaming aqueous phase system, has to use less, good anti-foaming properties, a wide range of acid, using a wide temperature range, does not affect the characteristics of being anti-foaming material.
