Description
Technical Field
[0001] The utility model belongs to the technical field of building material detection, and in particular relates to a water absorption tester. Background Art
[0002] The property of a material to absorb water in water is called water absorption. The water absorption of a material is expressed by water absorption rate, and currently it is often expressed by mass water absorption rate, which refers to the percentage of the mass of water absorbed by the material to the mass of the dry material when the material is saturated with water. Before testing the water absorption rate of building materials, it is usually necessary to dry the building materials to remove the moisture in the materials, and then soak the building materials. Therefore, it is necessary to use drying equipment and soaking equipment at the same time. The degree of integration is low, and it is troublesome to transfer the materials to be tested. In addition, since the density of some building materials is relatively small, such as filling cotton, foam bricks and other materials, they will float on the water surface during the soaking test and cannot be soaked. It is necessary to press a counterweight on the building material. However, the contact area between the counterweight and the building material is large, which may affect the water absorption rate of the building material, thereby affecting the accuracy of the water absorption test.
