Abstract

The invention discloses a method for quickly detecting the foaming property of a water-soluble emulsion. The method comprises steps of: introducing gas into a proper volume of sample to be tested to foam the emulsion and measuring the volumes of the foamed emulsion under different gas filling amounts, wherein the foaming property of the water-soluble emulsion can be represented according to the relationship between the gas mount and emulsion volume variation and the foam stability of the foamed emulsion also can be represented. The method can be utilized to accurately stimulate the foaming conditions of the water-soluble emulsion, needs a small amount of samples for detection, is convenient to operate, takes a short time and can conclude accurate detection results.

Description

1. Technical field [0001] The invention relates to a method for rapidly detecting the foaming performance of an aqueous emulsion. 2. Background technology [0002] Aqueous emulsion refers to a stable dispersion system formed by dispersing the dispersed phase in the form of particles or droplets in the dispersion medium with water as the continuous phase by physical or chemical methods. Common water-based emulsions include: styrene-acrylic emulsion, polyurethane emulsion, paraffin emulsion, etc., because the dispersion medium does not contain organic solvents, no pollution to the environment, no harm to operators, and it also has the advantages of low odor and non-flammability. It is widely used in adhesives, coatings, daily chemicals, food and other industries. [0003] In order to stabilize the performance of the aqueous emulsion, an emulsifier will be added during the preparation process. Due to the existence of the emulsifier, the surface tension of the system can be red...
