At present, how easy, measure the conductivity of dusty material exactly, still be one of the test difficult point in materialogy field.In traditional method, the general employing closely is pressed into fine and close bulk material with material, leads with the body electricity of four point probe resistivity surveys appearance measurement material again, calculates the bulk conductivity of material then through the complex mathematical formula.Also have and adopt the powder conductivity measurement of import directly to measure, but this instrument costs an arm and a leg, can not popularization and application.
Electric-resistivity method is generally adopted in the measurement of powder conductivity.Two ends at material add voltage, measure electric current and voltage drop through material, can obtain bulk resistor.The difficulty of measuring is, must guarantee that material is in impaction state, makes between powder granule and can closely contact, thereby overcome the influence of interface resistance.In addition, the outside will make two end faces be in state of insulation, thereby makes electric current only pass through powder body material.
Summary of the invention
The utility model provides a kind of electrical conductivity of powdered material test to use module for solving the problem that prior art exists.
The utility model purpose provides a kind ofly to be had simple in structurely, uses a small amount of powder, the bulk conductivity of accurately measuring powder body material directly perceived, good reproducibility; Measuring accuracy is high, and accurate measurement is with low cost; Be easy to clean, only need slide calliper rule and common multimeter, can obtain measurement result accurately.Used material can standardization be joined use mutually, and can observe the state after powder compresses.During measurement operating personnel's requirement and working environment are required lowly, the electrical conductivity of powdered material that is suitable for characteristics such as frequent uses in small test chamber is tested and is used module.
The utility model can be behind a spot of powder of packing into, and buckle well the termination up and down, is placed on the pressing machine to compress.Directly measure the resistance between the termination up and down with multimeter, can calculate the conductivity of powder body material easily.
The test of the utility model electrical conductivity of powdered material is adopted following technical scheme with module:
Module is used in a kind of electrical conductivity of powdered material test, is characterized in: test comprises upper end, lower end, interior bucket, outer sleeve with module, the corresponding assembling of upper end with lower end, and upper end and lower end are assemblied in interior bucket, and there is outer sleeve in the interior bucket outside.

Embodiment
For further understanding technology contents, characteristics and the effect of the utility model, enumerate following instance now, and conjunction with figs. specifies as follows:
Embodiment 1
With reference to accompanying drawing 1, Fig. 2 and Fig. 3.
Module is used in a kind of electrical conductivity of powdered material test, comprises upper end, lower end, interior bucket, outer sleeve, the corresponding assembling of upper end with lower end, and upper end and lower end are assemblied in interior bucket, and there is outer sleeve in the interior bucket outside, and the interior bucket outside has between outer sleeve by screw retention.Upper end and lower end are that brass is processed, and opposite face is smooth smooth; Interior bucket is processed for bakelite, and outer sleeve is that stainless steel is processed, and interior bucket and outer sleeve are circular configuration.
The specific operation process of present embodiment:
Like accompanying drawing 1, Fig. 2 and shown in Figure 3, the module groups assembling structure is made up of upper end 1, lower end 2, interior bucket 3, outer sleeve 4, gib screw 5.Wherein, upper end 1 can contact with lower end 2, and its height h1 in interior bucket 3 is greater than the height of interior bucket 3.
During assembling, pack lower end 2 into interior barrel earlier, a spot of powder sample of in the cavity that forms, packing into then, rolling is flat, installs termination 1 again.The module that assembles is placed on the pressing machine, and pressing is tight, the height h2 and the resistance R of measurement module.The conductivity ρ of powder body material calculates by following formula:
The ∏ r of ρ=(h2-h1)/2
2R wherein, r is the inside radius of interior bucket.
For keeping good electrical contact, upper end 1, lower end 2 are used the brass manufacturing, and surface grinding is smooth.Interior bucket 3 usefulness have the bakelite made of insulativity, guarantee the electrical isolation in the test process.Outer sleeve 4 is used the stainless steel manufacturing, guarantees closely to contact with interior bucket 3.Compress with gib screw 5 between interior bucket 3 and the outer sleeve 4.
This device can be behind a spot of powder of packing into, and buckle well the termination up and down, is placed on the pressing machine to compress.Directly measure the resistance between the termination up and down with multimeter, can calculate the conductivity of powder body material easily.
