Experiment Research on Moisture Transmission Rate between Humidity Sensitive Material and the External Environment

Abstract:

The intelligent water-saving valve without power supply is an equipment characterized by high automation, low costs and controlling without power supply, which is targeted to solve problems of water-saving irrigation equipment all around the world. To make this valve apply in production and irrigation better, this paper does research on transmission rate of moisture between humidity sensitive materials and external environment, and illustrates three rules: (1) For different types of soil, the fastest transmission rate of moisture between humidity sensitive materials and soil could be found in sand and the slowest one in clay. (2) For different ratios of humidity sensitive materials, the material water-absorption ratio performs faster when ratio is 1:1 than 1:3; and material water-loss ratio performs slower when ratio is 1:1 than 1:3. (3) For whether humidity sensitive materials contact with air or not, the transmission rate is faster when contacting with air.
