The invention discloses a device for detecting material shedding on the surface of a gas-permeable nano-membrane, which belongs to the field of nano-material detection equipment, and includes: an experimental system, including an experiment platform for placing the gas-permeable nano-film to be tested, and a plurality of devices arranged on the experiment platform. Exhaust pipe, the fixed plate positioned above the test bench and a plurality of intake pipes arranged on the fixed plate, the gas supply system includes a gas generating device installed on the test bench, and the gas supply system uses For supplying air to the intake pipe; and a detection system, including a laser particle counter and a flow meter installed on the exhaust pipe, the present invention is provided with a plurality of exhaust pipes and air intake pipes, which can ventilate the same sheet to be tested. Multiple positions of the nano-membrane are detected to obtain multiple sets of test results, avoiding contingency, reducing errors, and no need for the experimenter to cut the gas-permeable nano-membrane to be tested. During the detection process, it is convenient for the experimenter to perform centralized inspection and reduce the workload of the experimenter. .
Description
technical field [0001] The invention relates to the field of nanometer material detection equipment, in particular to a device for detecting material shedding on the surface of a gas-permeable nanometer film. Background technique [0002] Nano-membrane materials are composite sheets prepared by processing nano-scale raw materials as the main or secondary raw materials. They usually have the characteristics of air permeability. Due to the small particle size and large specific surface area of the material itself, many nano-membranes are formed. After that, it is easier to fall off, so it is more important to measure the shedding amount of nanoparticle materials in nanofilms; at present, there are not many methods for truly measuring the shedding amount of nanoparticle materials in nanofilms. Many methods of powder are mainly aimed at large particle substances; for example, paper hair loss, powder loss measurement, or some films that are easy to fall off; from the measuremen...
