Embodiment
Referring to Fig. 1, Fig. 2, the present invention provides the experimental method that a kind of quick measure sheet material makes moist amount of deflection, including following step
Suddenly：
Step 1, deflection metrology support is arranged on the top of a casing 1, the open top of casing 1, and inside fills liquid
Medium 10；Referring to Fig. 1；
Casing 1, open top, liquid medium 10 is filled in casing, immediately below test sheet material 2, for by liquid
State medium heat cause test sheet material 2 residing for environment temperature and humidity within a preset range.Temperature is in the present embodiment：(23
± 5) DEG C, humidity is：(50 ± 10) %, the liquid medium inside casing 1 is water.In the present embodiment, casing 1 is square, and shape
Shape and size are suitable with the shape and size for testing sheet material 2, the side plate 11 of the width of casing 1 relative to length direction side plate
12 overhang upwards, form deflection metrology support.
Deflection metrology support is used to install test sheet material 2；Deflection metrology instrument includes a vertical frame 3, and the top of vertical frame 3 is set
Level board 4 is equipped with, at least one measurement column 5 for being used to measure the test amount of deflection of sheet material 2 is equipped with level board 4, is set on measurement column 5
It is equipped with scale and is threadedly coupled between level board 4.Vertical frame 3 is arranged on the center of casing 1.Level board in the present embodiment
On be provided with two measurement columns 5, respectively from the amount of deflection of two position measurements test sheet material, many places take a measurement, are advantageous to calibrate
Measurement result, for the test sheet material 2 suitable for different in width, it can be set on width of the level board 4 along test sheet material 2
It multiple screwed holes 41, can coordinate with measurement column 5, when the size for testing sheet material 2 changes, may be such that measurement column 5 in screw thread
Selected in hole 41.
Step 2, test sheet material 2 is placed on deflection metrology support, and causes the opening of test sheet material face casing, led to
Cross the reading H1 of deflection metrology instrument measure test sheet material center；Referring to Fig. 2；
Step 21, test sheet material 2 both ends are placed on the biside plate 11 in box width direction；
Step 22, the measurement column 5 on deflection metrology instrument level board 4 is rotated so that measurement column 5 is moved downward to its bottom
Contradicted with the centre of the tested upper surface of sheet material 2, and record reading H1.
Step 3, the liquid medium inside heating compartment, and by temperature and humidity control within a preset range；
Box house is provided with electrical heating elements 6.Water inside casing 1 is heated by Electric heating.Electrical heating
Element 6 is prior art, be will not be repeated here.
Step 4, after heating 20 minutes, the reading H2 of test sheet material 2 center is determined again by deflection metrology instrument；
Wheel measuring post 5 again so that measurement column 5 is moved down and contradicted with the upper surface of test sheet material 2 after deformation of making moist, and is remembered simultaneously
Record reading H2；
Step 5, made moist amount of deflection, i.e. H1-H2 by calculating acquisition.
This experimental method produces heat with test sheet material directly by being heated to the water of box house, by the evaporation of water and handed over
Change, and then temperature conditionss and relative humidities, because test sheet material is directly placed on casing, water vapour can be directly to
Up on test sheet material, temperature conditionss and relative humidities can quickly meet, without the environment temperature to whole laboratory
Debugged with humidity, just can reach requirement of experiment within 20 minutes, not only increase measuring speed, and save the energy, more ring
Protect.
