According to the charge attenuation measuring device disclosed by the invention, firstly, the sample to be detected is electrified, and then the charge attenuation process of the sample to be detected is measured, so that accurate data can be provided for the research on the electrostatic performance of the sample to be detected.
Description
Technical field
The present invention relates to charge measurement field, relate in particular to a kind of charge decay measurement mechanism.
Background technology
In fact the electrostatic electrification process of object is exactly the homeostasis process of charge generation and dissipation.Insulated with material degree is higher, electrostatic charge is just longer die-away time, and leak charge ability is more weak, and band power is just stronger, thereby the possibility that causes electrostatic hazard is just larger, so electrostatic charge die-away time and electrostatic charge decay half life period are the important parameters of weighing material antistatic performance.In view of this, the present invention proposes a kind of charge decay measurement mechanism, first sample is electrified, and then measures the charge decay process of sample, thereby can provide accurate data to the antistatic property of research sample.
Summary of the invention
In view of this, the invention provides a kind of charge decay measurement mechanism, comprise electrometer, barricade, concentric ring electrode, insulation course, high-voltage DC power supply, wherein, described concentric ring electrode comprises central electrode and limit electrode, described central electrode connects high-voltage DC power supply, limit electrode grounding, sample is positioned on described concentric ring electrode, described concentric ring electrode is positioned on described insulation course, described electrometer, when described sample charging, is isolated by barricade and sample.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or scheme of the prior art, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the charge decay measurement mechanism that Fig. 1 provides for one embodiment of the invention.
Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is carried out to clear, complete description, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belongs to the scope of protection of the invention.
The structural representation of the charge decay measurement mechanism that Fig. 1 provides for one embodiment of the invention, as shown in Figure 1, the charge decay measurement mechanism of the present embodiment, comprise electrometer 1, barricade 2, concentric ring electrode, insulation course 6, high-voltage DC power supply (not providing in figure), wherein, described concentric ring electrode comprises central electrode 4 and limit electrode 5, described central electrode 4 connects high-voltage DC power supply, limit electrode 5 ground connection, sample 3 is positioned on described concentric ring electrode, described concentric ring electrode is positioned on described insulation course 6, described electrometer 1 is when described sample 3 charging, by barricade 2 and sample 3 isolation.
The device of the present embodiment adopts concentric ring electrode, and in test process, makes sample one straight through limit electrode grounding.During test, the shielding of electrometer conductively-closed plate, high-voltage DC power supply charges to sample by central electrode, deenergization after sample charges to voltage stabilizing, remove barricade, electrometer gets off the surface potential value record of sample, thereby obtains the die-away curve of electric charge, and calculates thus electrostatic charge die-away time.
Finally it should be noted that: above embodiment only, in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement, and these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
