Sharing of operating procedures for leather permeability and vapor performance testing machine

1、 Instrument Introduction:

Fix the circular test piece on the opening of a test bottle containing a certain amount of solid desiccant in the water vapor permeation testing machine, and use the test piece to separate the desiccant inside the bottle from the air outside the bottle. By turning on the water vapor permeation testing machine to rotate the test bottle and the fan that disturbs the air, the constantly moving desiccant continuously absorbs the water vapor passing through the test piece. Within a certain period of time, evaluate the water vapor permeation performance of the test material by weighing the mass of water vapor absorbed by the desiccant in the test bottle.

IIMain functions:

experimentTest the ability of the upper and upper shoe materials, including the leather surface and lining, to resist water vapor penetration.
