Problems solved by technology
[0002] At this stage, the liquid drainage method is generally used to measure the density of materials, but when measuring porous materials, water easily penetrates into the pores of porous materials, resulting in the volume of discharged water being the overall volume of the porous material minus the volume of the pores in the material, so that The density test result is inaccurate. In order to prevent water from entering the pores of porous materials, polymer materials are often used as waterproof membranes. However, it has been proved that waterproof membranes are difficult to completely prevent water seepage, especially for parts with complex shapes. In order to solve the above problems, a this invention

The invention discloses a porous material density detection device. The porous material density detection device comprises a detection box, wherein the detection box is provided with a detection cavity, a through hole penetrating through upper and lower parts is formed in an inner wall of the detection cavity, storage cavities are symmetrically arranged in left and right inner walls of the throughhole, sealing plates are slidably arranged in the storage cavities, jacking springs are connected between the sealing plates and the inner walls of the storage cavities, a porous material is placed in a cavity with a fixed volume, the cavity is filled with fine sand, and the diameter of the fine sand is slightly larger than the diameter of the pores in the porous material, so as to prevent the fine sand from entering the pores, there is no gap among the fine sand in the cavity through multiple times of vibration and multiple times of addition, furthermore, the fine sand sufficiently wraps theporous material, so that the volume of the porous material can be obtained by checking the volume of the added fine sand to calculate the density.
Description
technical field [0001] The invention relates to the technical field of density detection, in particular to a porous material density detection device. Background technique [0002] At this stage, the liquid drainage method is generally used to measure the density of materials, but when measuring porous materials, water easily penetrates into the pores of porous materials, resulting in the volume of discharged water being the overall volume of the porous material minus the volume of the pores in the material, so that The density test result is inaccurate. In order to prevent water from entering the pores of porous materials, polymer materials are often used as waterproof membranes. However, practice has proved that waterproof membranes are difficult to completely prevent water seepage, especially for parts with complex shapes. In order to solve the above problems, a this invention. Contents of the invention [0003] The technical problem to be solved by the present inventi...
