Abstract

A device and a method for rapid testing of degree of wetting of a dustfall agent are disclosed, the device comprises a contact angle test section, a wetting speed test section, a surface tension test section and a computer processing section; the method uses the above device for testing, a liquid level signal is converted into a current signal by a liquid level sensor, and wetting speed can be accurately determined; based on Wilhemly principle, a pressure-sensitive sensor is used for rapid determination of the contact angle of a dust sample and a dustfall agent solution; a surface tension sensor is used in conjunction with a computer numerical model to determine critical micelle concentration; and finally the wetting speed is used as a basis parameter, the contact angle is used as a preferable parameter, the critical micelle concentration is used as a cost parameter, and the degree of wetting Favc for comprehensive characterization of wettability of the dustfall agent can be obtained. The device is fast in test speed and high in accuracy, the testing device is intelligent and simple in operation, and the device has broad applicability in the development and optimization of various types of dustfall agents.

Description

technical field [0001] The invention relates to a device and a method for testing the wetness of a dust suppressant, in particular to a device and a method for quickly testing the wetness of a dust suppressant, belonging to the field of dust prevention and control. Background technique [0002] Dust is the main occupational hazard in mining, construction, building materials, metallurgy and other industries, and seriously endangers the health of workers. Water spray is currently the most commonly used technology for dust prevention and control. However, due to the high surface tension of water, it can reach 72mN / m Most of the permanent dust is hydrophobic, so the dust removal efficiency is low. Adding dust suppressant to water to reduce the surface tension of the solution and increase the hydrophilicity of dust is an important way to improve the effect of spray dust suppression. However, due to the lack of devices and methods that can comprehensively test the wetting propert...
