The method of compound space charge behavioral implications.
The judgement haloflex filler includes following step to the method for polyethylene composite space charge behavioral implications
Suddenly：
It is prepared by step 1, sample；Haloflex is existed with 0.5%, 1%, 3%, 5% proportioning and polyethylene respectively
Melt blending on 110 degrees Celsius of torque rheometer, is prepared into composite.Again in the case where pressure is 15MPa, 130
Degree Celsius vulcanizing press on be hot pressed into sheet metal specimens, the press time is 30 minutes.Obtained sample is finally placed in baking oven
In be heat-treated 24h at 80 degrees celsius, to eliminate shadow of the pressure with cooling velocity difference to crystallization degree in sample pressing process
Ring；
Step 2, carry out disruptive field intensity experiment；Direct current is carried out to the polyethylene sample for being mixed into haloflex at normal temperatures
Breakdown test, the disruptive field intensity that processing data is obtained using Weibull distribution, and contrasted with pure polyethylene；
Step 3, nano combined polyethylene conduction current specificity analysis；Obtain the relation of Current Voltage；
Step 4, space charge measurement；The measurement of space charge, research pressurization shape are carried out to sample using pulse radio-acoustic method
State space distribution of charges and short-circuit condition distribution of space charge, by the release conditions of its space charge of short-circuit analysis, and according to
TSC inquires into trapping state in composite；
Step 5, microstructure, judge haloflex filler to polyethylene composite space charge behavioral implications；To examination
Sample is scanned electron microscope experiment (SEM), deployment conditions of the observation haloflex in polyethylene, it was therefore concluded that.
Preferably：
The nano combined polyethylene conduction current characteristic analysis method comprises the following steps：
Step 1, test product is pressed into film, then dried 24 hours at 60 DEG C, plate a diameter of 30mm's in film both sides
Aluminium electrode, test product is put into sealed sample room；
Step 2, the nitrogen for being filled with abundance exclude oxygen, the temperature of temperature control box are adjusted, after temperature stabilization, to test product
Applying voltage makes its electric-field intensity reach E0；
Step 3, current data is gathered, and the data gathered every time are contrasted, if comparing result is in the mistake of setting
Within poor scope, then preserve the current data, and by voltage increase Estep；
Step 4, aforesaid operations are repeated, until voltage is raised to final voltage；
Step 5, voltage obtain multiple corresponding electric currents and voltage data point after being raised to final voltage, data point are connected
Into line, you can obtain the relation of Current Voltage, the i.e. relation of I-V curve or current density and field strength, i.e. J-E curves.
The present invention has the following effects that compared with existing product：The sky of haloflex/polyethylene polymer can be measured
Between distribution of charges rule, the influence of space charge can be reduced by the addition of haloflex, while in electrical conductivity and breakdown
Also improved in terms of field strength.
