System and method for detecting foam inhibition property and defoaming property

Abstract

The invention belongs to the technical field of foam detection, and particularly relates to a foam inhibition and defoaming performance detection system which comprises a supporting assembly, a foaming assembly, a quantitative testing assembly and a control assembly. The quantitative test assembly comprises a quantitative test container, a clamp and a test plate; the bubbling assembly comprises a ventilation rotating shaft and a turntable; the control assembly comprises a gas supply device, a controller and a power system for providing power for rotation of the ventilation rotating shaft and lifting of the clamp. The supporting assembly is used for supporting the foaming assembly, the power system and the clamp. According to the invention, the foaming process can be truly simulated, and the foam inhibition and defoaming properties of the sample can be accurately and quantitatively reflected at multiple angles.

Description

Technical field [0001] The present invention belongs to the technical field of foam detection, and more particularly to a detection system and method for inhibition and defoaming property. Background technique [0002] For aqueous double-component coating, dip painting and other susceptible materials, after construction, easy to cause surface defects of paint film, affect the anti-corrosion resistance, weather resistance and paint film of the paint film, and easy to drag down construction progress, increase construction cost. There is no national standard, and there is no corresponding inhibition property, defoaming index requirements and support detection methods in the labeling. [0003] Patent CN202011337996.7 discloses a foaming apparatus for aqueous coating test, there is a single, unfoiled evaluation index of a single, coating resistance, and defoaming property, and other disadvantages. Patent CN201720118679.3 discloses a defoamer defoamemic performance test device, existen...
