Description

technical field

[0001] The invention relates to a filter cloth performance detection method, in particular to an online filter cloth performance detection method, which is used for liquid content, filtrate, air permeability, overall elasticity, surface elasticity and flatness of filter cloth in papermaking, chemical industry and other industries Online detection of comprehensive performance. Background technique

[0002] Filter cloth is a necessity in the filtration process of the paper industry and chemical industry. The comprehensive properties of the filter cloth, such as liquid content, filtrate, air permeability, overall elasticity, surface elasticity and flatness, directly affect the production efficiency and product quality of the filtration process. and production costs. For this reason, it is very important to detect the comprehensive performance of the filter cloth online, so as to grasp the change trend of the filter cloth performance, make effective adjustments ...
