The influences of calcium carbonate(CaCO3),talc and silica on the flame-retardancy of ethylene vinyl acetate(EVM)/nitrile rubber(NBR)composites filled with flame retardants magnesium hydroxide and zinc borate were studied and compared by limiting oxygen index(LOI) method and cone calorimeter. The results showed the ad…
Objective: To develop the formulation of thermoreversible microemulsion-based gel containing itraconazole(ITZ-MBG) using an O / W microemulsion-based gel system.Methods: Through solubility experiment and pseudo-tertiary phase diagrams,the compatible combination of oils,surfactants,cosurfactants and Km were screened.So…
Yttria-stabilized zirconia(YSZ) electrolyte film was prepared by screen-printing technology.The presintering temperature of porous NiO-YSZ hydrogen electrode substrates used in solid oxide electrolysis cells(SOEC) was optimized.A single fuel cell of Ni-YSZ/YSZ(10 μm)/LSM-YSZ was successfully prepared by screen-printin…
The optimal design of a claw-pole alternator was performed using quasi-Newton method,pattern search method as well as the combination of both methods.For the low efficiency of the claw-pole alternator,the equivalent magnetic circuit of a 2.1 kVA electric excitation claw-pole alternator was presented using Ansoft RMxpr…
By means of tensile test and metallographic test,the paper discusses the influence of boron on the tensile properties of steel.The results show that the boron reduces the yield strength and tensile strength of steel,but the elongation has no change.The boron increases the grain size,which is mainly reason of the yield…
The certified reference material sample and artificial calibration sample were used to plot the calibration curve,and the limestone sample was directly fused with anhydrous lithium tetraborate as flux without ignition loss correction for the carbonate in limestone.Consequently,CaO,MgO,SiO2, Al2 O3 and Fe2 O3 contents…
To improve the surface properties in solution,a series of imidazolum Gemini surfactants with methylene spacer chains were synthesized.The structure of the target product is characterized by 1HNMR. The surface tension of imidazolum Gemini surfactants was measured at 25 ℃.The results show that the synthetic imidazolum G…
The high cycle tension-tension fatigue tests(stress ratio was 0.1)of smooth and triangular notched samples of nickle-based superalloy M951 were performed at 700 ℃ and 900 ℃,and the fracure morphology were analysed.The results show that M951 alloy had superior high cycle fatigue properties at elevated temperatures.At 7…
The structure and materials of wood-based panel door leaves filled with honeycomb paper are analyzed.Based on the actual production of wood-based panel door leaves filled with honeycomb paper of Kunming Hongta Wood Industry,focus is placed on the production process of wood-based panel door leaves and the quality probl…
Compact NiO film was prepared on the surface of AZ91 Mg alloy by liquid-phase deposition so as to improve the corrosion resistance. The surface and cross-section morphology of as-prepared NiO film were observed with a scanning electron microscope,and its composition was analyzed with an X-ray diffractometer. Moreover,…
In order to improve corrosion resistance of the SiCp/Al composite material,it was treated by electroless Ni plating firstly and then the rare earth coatings were deposited on the surface of it.The effects of the Ce(NO3)3 concentration of rare earth solution and deposition time on the corrosion resistance of Ni-P coati…
8-hydroxyquinoline aluminum(Alq 3) was a kind of important organic electroluminesence material,with good film-forming property,thermal stability and electronic conductivity,and were widely used in the preparation of various organic light emitting device.The device had a flat,active emitting,high brightness,high contra…
The silicotungstic acid( SiWA) modified carbon supported Pd( Pd /C-SiWA) catalyst was prepared with immersing method. The chronoamperometric experiment shows that the current density are 0. 013 A / mg and 0. 082 A / mg at 3000 s for the Pd / C and Pd / C-SiWA catalysts,which are the 2. 5% and 14. 1% of that at 10 s,re…
