Humidity regulating material performance detection device and humidity regulating material performance detection method

Abstract

The invention discloses a humidifying material performance detection device and a humidifying material performance detection method. The humidity regulating material performance detection device comprises a constant temperature and humidity box, a balance located on the upper portion of the constant temperature and humidity box, a lifting table arranged in the constant temperature and humidity box and a sealing bottle with a hole and arranged on the lifting table. A connecting rope is connected to the lower end of the balance and downwards penetrates through the upper wall of the constant temperature and humidity box, the hollow pipe and the sealing cover in sequence, and a sample table is connected to the lower end of the connecting rope. The invention discloses a humidity regulating material performance detection method. The method comprises the following steps: placing a perforated sealing bottle filled with a test solution on the lifting table; after the preset humidity and temperature are reached, the lifting table rises to drive the sample table filled with the sample to be placed in the inner cavity of the perforated sealing bottle, and an effective sealing test space is formed among the perforated sealing bottle, the sealing cover, the hollow pipe and the balance; when testing begins, the balance records the weight change of the sample. According to the invention, the adverse effect of blast on weighing can be reduced, the sample weight change is automatically weighed and recorded in real time, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of humidity control performance detection of humidity control materials, in particular to a performance detection device for humidity control materials and a performance detection method for humidity control materials. Background technique [0002] Indoor air humidity is closely related to human health. Studies have shown that when the indoor humidity is lower than 40% or higher than 70%, it will cause physical discomfort and various complications. Therefore, in order to adjust the indoor air humidity and meet the energy-saving requirements of buildings, various humidity-regulating materials have been invented. The evaluation of the humidity control performance of such materials is usually to detect the change of the material's own weight caused by the adsorption or desorption of water vapor over time. The traditional detection method is to manually take samples and weigh them, and put the samples back after recordin...

AI Technical Summary

Problems solved by technology

The traditional detection method is to manually take the sample and weigh it, and put the sample back after recording the data. Since the sample is out of the set humidity environment during the sampling process, the accuracy of the continuous test is reduced, and the tester needs to take samples repeatedly during the long-term test.
