    Porous Detector

    Overview Knowledge Standards Terms
    The porous probe measures material porosity through gas permeation and calculates pore size distribution using pressure changes. It is used to detect the air permeability and pore structure of materials such as paper and filter membranes, ensuring product uniformity in quality control.
    Selection
    When selecting, consider that the measurement range should cover the sample aperture, gas compatibility should match material characteristics, and the operational procedure should be suitable for the testing environment. Pay attention to the validity of the calibration certificate and data repeatability, and choose the fixture type based on the sample morphology.

    Porosity Control in the Preparation of Porous Coatings During the Blade Coating Process
    Doctor blade coating is a wet coating technique widely used for preparing functional coatings, which involves uniformly applying a slurry containing solid particles (such as ceramics, polymers, or metal oxides) onto a substrate, followed by drying and heat treatment to form the coating.
