Hole, connect each data line, electronic scale put warm leveling, desiccant is put well, cabinet is sealed.
After preparation is carried out, in temperature parameter control interface, fill in respectively hot tank and moisture vasculum need it is warm and humid
Control point is spent, metering temperature control is clicked and starts to test.Hot tank can keep certain temperature and humidity, and the environment in moisture acquisition is empty
Between size and current temperature and humidity can be converted into the weight of moisture in air, water-absorbent material is started to work, and weight starts slowly
Increase, the electronic scale in moisture collection case starts to acquire data, this tests no time restriction, and general primary test needs to grow very much
Time at the end of needing, is clicked and stops.
This, which is tested, needs to record the temperature and humidity point of hot tank and moisture vasculum, as to acquire the temperature inside the box constant 20 for moisture
DEG C, in normal pressure, when working after a few days, the variation and calculating that are weighed by electronic scale can regard the biography of wetness as
It leads.If there are different pressure for test, influence of the pressure to humidity is also contemplated that when calculating.
Wφ is passed=WAfter φ-WBefore φ-Wφ is poor
Wherein, Wφ is passedFor the weight for conducting moisture；
WAfter φThe weight of desiccant after stopping for conduction；
WBefore φThe weight of drying prescription when hopping to it for preceding conduction；
Wφ is poorFor difference conduction start when desiccant relative humidity subtract conduction at the end of relative humidity difference.
5. moisture permeable is tested
