Fully automatic membrane pore size analyzer model: Location: Mainland China Release time: 2018/8/9 14: 23: 53 Purchasing popularity: 219 Introduction content: 3H-2000PBFully automatic membrane pore size analyzer, which can accurately test the pore size, minimum pore size, average pore size, pore size distribution and permeability of through holes of filter membranes, diaphragms, fabrics, fibers, ceramics, sintered metals and other materials, suitable for Research and development, production of filter materials and related scientific research units and corporate users.

Detailed introduction Fully automatic membrane pore size analyzer test theory: Taking a certain membrane material as an example, the membrane is fully wetted with a liquid that can be infiltrated with it.

Due to the existence of surface tension, the infiltrating liquid will be bound in the pores of the membrane; gradually increase the gas pressure on one side of the membrane, When the gas pressure reaches a pressure greater than the pressure generated by the surface tension of the infiltrating liquid in a certain aperture, the infiltrating liquid in the aperture will be pushed out by the gas; since the smaller the aperture, the higher the pressure generated by the surface tension, so it is necessary to push out the infiltrating liquid in it.

The gas pressure that needs to be applied is also higher; similarly, it can be seen that the infiltrating liquid in the hole with the aperture will be pushed out first, allowing the gas to permeate, and then as the pressure increases, the aperture will change from large to small, and the infiltrating liquid in the hole will be pushed out first.

It is pushed out in turn to allow the gas to permeate until all the pores are opened to achieve the same permeability as the dry film; The pressure corresponding to the hole that is opened first is the bubble point pressure, and the pore size corresponding to this pressure is the pore size; during this process, the pressure and flow rate are recorded in real time, and the pressure-flow curve is obtained; the pressure responds to the information of the pore size, and the flow rate responds The information about the number of pores of a certain pore size; and then test the pressure-flow curve of the dry membrane, and the pore size, average pore size, minimum pore size, pore size distribution, and transmittance of the membrane sample can be calculated according to the corresponding formula.
