Performance testing equipment for humidifying function material and testing method

Abstract

The invention discloses performance testing equipment for a humidifying function material and a testing method. The equipment disclosed by the invention comprises a relative humidity control part, a weighing part and a temperature and humidity monitoring part, wherein the relative humidity control part is a mechanical constant temperature cabinet system, a humidity change equipment system or a saturated saline water solution system and is provided with a closed space with adjustable temperature and humidity; a temperature probe and a humidity probe of the weighing part and the temperature andhumidity monitoring part are arranged in the closed space; the weighing part is an electronic balance; and the electronic balance, the temperature probe and the humidity probe are connected with a computer which is arranged outside the closed space. By means of different temperature and humidity control modes, the humidity absorption and release performances of the material are detected through ahumidity reaction method; the computer records the data of a detection sample which is weighed by the electronic balance in real time; and the humidity absorption and release capabilities of the sample are obtained by computing. The invention can accurately detect the humidifying performance of the material, and a testing result has good stability.

Description

technical field [0001] The invention belongs to the field of material testing and relates to a performance testing system for novel humidity-adjusting functional materials. The system includes test equipment and test methods, which can be used to test the humidity control performance of various materials by the humidity reaction method. Background technique [0002] The level of relative air humidity affects people's work and life. Humidity control is particularly important for people's living environment and protection of objects. With the development of technology and new material technology, people have successively developed materials with humidity adjustment function, and widely used this material in building materials, textile products and other products, so that traditional products can not only meet the original use function, but also have It has the ability to adjust the relative humidity of the environment and improve the comfort of the living space. [0003] The...

AI Technical Summary

Problems solved by technology

However, since the internal air velocity cannot be controlled, and the air flow on the surface of the test sample has a great influence on the test results, it is necessary to solve this problem and form a more complete humidity control performance detection system; on the other hand, due to the need for electronic balance readings, often To open and close the door of the test chamber during the experiment will affect the stability of the test environment
