The pressure sensor for the size that is under pressure.
Further, the press mechanism includes support frame and is fixed on arranging on support frame as described above downwards
Press rods, the press rods are located at the top of the testing stand.
Further, support frame as described above includes perpendicular strut and the company that two intervals are fixed on the table top of the testing stand
The singletree between two perpendicular struts is connect, the press rods are fixed on the singletree.
Further, the upper end of the press rods is equipped with the pressure sensor, and the pressure sensor is fixed on described
On support frame.
Further, the lower end of the press rods is equipped with briquetting.
Further, the motor for driving the press rods is equipped in the testing stand.
It further, further include Hygrothermograph.
It further, further include display, the electrostatic transducer is connect with the display.
Further, the table top of the testing stand is equipped with electro-insulating rubber pad.
The beneficial effects of the present invention are embodied in:
The configuration of the present invention is simple, be easy production, it is easy to use, can quickly measure material it is basic can charged characteristic,

Embodiment and embodiment in feature can be combined with each other.
Referring to Fig. 1.
The present invention separate electrostatic electrification experimental provision, including testing stand 1, electrostatic transducer 2, for test specimen to be compressed
It press mechanism 3 on the testing stand and is under pressure the pressure sensor 4 of size for measuring test specimen.
Two kinds of object contacts, distance is less than 25 × 10 therebetween-8When cm, since the ability of not homoatomic receiving and losing electrons is different,
The energy level of different atoms outermost electronics is different, and the transfer of electronics occurs therebetween.Therefore, interface two sides will appear it is equal in magnitude,
Opposite polarity two layer charge.This two layer charge is known as electric double layer, and potential difference therebetween is known as contact electromotive force.According to electric double layer
With the theory of contact electromotive force, when can deduce that the close contact of two kinds of substances separates again, it is possible to generate electrostatic.
The present invention is according to above-mentioned principle, in use, taking two pieces of test specimens, one piece is placed on testing stand, and another piece is fixed on
The pressing end of press mechanism, electrostatic transducer is placed in measurement range, starts press mechanism later, and two pieces of test specimens are pressed from both sides
Tightly, a period of time is kept, then replys press mechanism, the electrostatic precipitation situation of test specimen is obtained by electrostatic transducer.
Different pressures value and different pressure times are applied to testpieces by setting, then test specimen is measured by electrostatic transducer
Surface electrostatic deposition, can measure the basic of material can charged characteristic.
