1,3,5-Trimethyl-2,4,6-tri-(3,5-di-tert-butyl-4-hydroxybenzyl)benzene is a high molecular antioxidant agent of hindered phenol type featuring low volatility, excellent insulating property and good compatibility with polymers.
The material remained preferable mechanical properties and some insulating properties when the MgO content was 70% and thermal conductivity was 1.9 W/(m·K).
The powder X-ray diffraction patterns indicate that the excess amount of Mg lead easily to the insulating MgB-6 and MgO impurities and the solubility of Mg in MgB-2 is limited.
Using tetrafluoroethylene-hexafluoropylene coplymer(FEP) as a matrix,aluminum nitride(AlN) particles modified by coupling agents as filler,the FEP/AlN composites with high thermal conductivity and insulating charateristics were achieved by the blending and hot press molding in this paper.
This paper described the features,insulating structure,anti -seismic characteristics and coil designing for HV current transformer of internal insulating gas SF6.
By the substitution of Ca for Y, the holes are introduced into the insulating host material YBa2Cu3O6, and an insulator-to-metal transition, as well as superconductivity at 60K, is observed. The measurements of crystal structure, resistivity and ac susceptibility are performed, and the results indicate that the CuO planes with sufficient carrier concentration is the important condition for sustaining the high-Tc superconductivity.
The powder X-ray diffraction patterns indicate that the excess amount of Mg lead easily to the insulating MgB_6 and MgO impurities and the solubility of Mg in MgB_2 is limited. The resistivity in normal state increases rapidly with increasing x.
In this study, electrorheological behavior of suspensions prepared from 0.9 and 5.0 μm calcium carbonate particulates, dispersed in insulating silicone oil medium was investigated.
It is shown that insulating films of low conductivity are formed around particles at a concentration corresponding to coating of graphite particles with a monolayer of the surfactant and the conductivity of the sediments sharply decreases.
Calculations are performed for a boundary layer on a plane thermally insulating plate, and the effects of the transverse velocity component and the three-dimensionality of the perturbations on stability at various Mach numbers are demonstrated.
An electronic circuit which may be applied to the control of firing angle of high voltage mercury arc current converter is suggested in this paper.The circuit mainly consits of two parts:the primary pulse generator and the secon- dary pulse former.Between these two parts is inserted an insulating transfo- rmer which transmits the control paise and isolates the high potential difference between them.The primary generator generates the control pulses and determinates their phase.The secondary pulse form...
In this paper we get the approximate distributions of the electric potential fields by use of the method of separation of variables under the following premiss:1, We neglect the influence of the insulating rings connecting the principal elect-rode and the guard electrodes;2, We restrict to the case of media of slowly varying resistivities and conse-quently neglect the influence of the refraction of electric current. We also suppose that the current density of the electrode system is nearly homogeneous...
In this paper the saturation water value in Benzene and N-Heptane under different temperatures is taken as the standard. GDX-101 is selected as stationary phase (column length 1 m. Φ3 mm.). N_2 is used as supporting gas. The traces of moisture in electric insulating oils are determined by thermal conductivity detector, and a comparison with the electric method is made.
