Become to seal cavity, two-part sample to be tested will be divided into and be respectively placed on upper and lower fixture place, and use negative pressure
Two-part sample to be tested is adsorbed in respectively first holder wall with holder aperture 6 of upper and lower fixture
On body 4-1, thus play the effect of fixing sample to be tested, and keep sample do not deform, by upper,
Lower clamp all is attached using by the device of connector with tensile testing machine or recordable displacement and power.
Embodiment 2
Fig. 2 is the structural representation of the embodiment 2 of half finished rubber mutual viscosity test fixture of the present invention.Real
Execute the structure of fixture described in example 2 identical with the structure of fixture described in embodiment 1.The unvulcanized rubber of the present invention
Glue mutual viscosity test fixture, described fixture includes fixture and lower clamp, described upper fixture and lower clamp knot
Structure is identical, and described upper fixture and lower clamp all include connector 5, holder wall 4, holder aperture 6, airduct
8。
As in figure 2 it is shown, the structure of fixture described in embodiment 2 is different from the structure of fixture described in embodiment 1
Part is only that, described upper fixture and lower clamp the most also include aperture plate 9.The outer surface of described aperture plate
Contact with the outer surface of described first fixture wall body.
Further, in described aperture plate uniform porose 3.
The absorption affinity size of sample to be tested is calculated, wherein by described fixture according to generalized formula F=P × S
F represents absorption affinity, unit N；
P represents the pressure of vacuum equipment, units MPa；
S represents area sum porose in aperture plate, and if any n hole, each area is s, then
S=n × s.
With pressure as 0.2Mpa, aperture number be 36, as a example by a diameter of 4mm in aperture, absorption affinity
F=P × S=P × n × s=P × n × π × 1/4 × D2=0.2MPa × 36 × 3.14 × 1mm2=22.608N.
Therefore, the absorption affinity influence factor of sample has aperture number, aperture area (or diameter).Different
Aperture plate there is different aperture number, aperture area, the present invention is by selecting the aperture of different pore size
Plate, can be adjusted sample to be tested absorption affinity, thus realizes the size according to various sample bonding force
Regulation absorption affinity.
And in aperture plate hole be shaped as beneficially calculating the shape of hole area, as being circular, triangle
Shape, rectangle etc..
