Description

Technical Field

[0001] The utility model relates to the technical field of sheet material testing, in particular to a device for testing the water vapor resistance of sheet materials. Background Technique

[0002] The water vapor test and boiling water test of sheet materials are both test methods for evaluating the performance of materials in humid or high-temperature water environments, but they have different focuses, and the test purposes and conditions are different.

[0003] The water vapor test mainly evaluates the air permeability and moisture-proof performance of sheet materials in a high-humidity environment. It determines the water vapor transmission rate of sheet materials by measuring the amount of water vapor passing through a unit area of the sheet material per unit time under specific temperature and humidity conditions. This test can reveal the moisture-proof ability of the sheet material and its dimensional stability in a humid environment.

[0004] The boiling water test, on the other hand, focuses more on the performance of sheet materials in direct contact with high-temperature water or boiling water, such as water resistance, bonding strength, and structural stability. During the test, the sheet material sample is immersed in boiling water for a period of time, and then the degree of its expansion, delamination, cracking, or other physical changes is observed. The boiling water test can test the bonding quality of sheet materials, especially for composite sheet materials bonded with glue, such as plywood and density board. It can evaluate the durability of the glue under high temperature and high pressure.

[0005] When conducting the existing water vapor test and boiling water test of sheet materials, usually two devices are used, and then the sheet materials are placed in the environments of boiling water and water vapor respectively for different tests. While the two devices occupy a large area, the test operation of the same sheet material between the two devices also increases the work intensity and affects the production efficiency. Therefore, in order to solve the above technical problems, a device for testing the water vapor resistance of sheet materials is proposed. Content of the Utility Model
