Influence of composite pore former on the properties of light-weight castables for corundum-anorthite-mullite are researched in this article using the polystyrene spheres and carbon black as complex foam agent,and the best content for polystyrene spheres and carbon black was determined.Phase composition of light-weigh…
An ionic liquid,1-butyl-3-methylimidazolium chloride(BMIMCl),was used as solvent to prepared silk fibroin(SF) solution.It was then blended with polyvinyl alcohol(PVA) solution to obtain blending films.The blend films were characterized by infrared spectrum,ultraviolet-visible spectrum,contact angle and mechanical prop…
Insulators coated with RTV which operate for several years will be aged,and result in RTV coating failure.This paper presents the method to judge RTV coating aging and life expectancy,as well as aging treatment of RTV coating.This study provides a theoretical basis about RTV coatings in the widespread application of p…
The cement-based composite shielding materials was made of cement and shielding mediums,such as graphite,carbon black,carbon fiber,nano-carbon-tube et al,which were dispersed by different method.The effects of these shielding mediums on shielding properties were studied and the relationships of the content of carbon f…
A novel method of hydrogen production from aqueous methanol solutions under low-frequency ultrasound was systematically studied under low frequency and the mechanism of production hydrogen was explained.The influence rules of parameters such as temperature,concentration,ultrasound amplitude etc.on H2 yield and product…
PbWO4 microcrystals with different Y3+ doping concentration were prepared by hydrothermal me-thod in an ethylene glycol-distilled water mixed solvents,and were characterized by X-ray diffraction(XRD),X-ray fluorescence(XRF) and photoluminescence(PL) spectra.The results revealed that the relative intensity of luminesce…
Adopting new developed inorganic compound soluble quenchant JEF-G35,microstructure,hardness,bending property and impact toughness of GCr15 steel were analyzed by a series of optical microscope,impact-toughness tester and microcomputer control electronic universal testing machine.Effect of quenching medium temperature…
A series of PdZn/ZrO_2 catalysts were prepared by deposition-precipitation method,which was mechanical mixed with ZSM-5/γ-Al_2O_3 as the catalysts for steam reforming of dimethyl ether (DME).The effects of palladium precursors,Zn/Pd molar ratio and reduction temperature on the catalytic performance of PdZn/ZrO_2 were…
Continuous extrusion under large expansion ratio is a new technology for manufacturing copper strip.Preventing mould and die structure are important effecting factor of deformation.Based on the characteristic of the forming process,the model of rigid-plastic FEM on DEFORM-3D was established and the numerical simulatio…
A 3-D FEM model for radial-axial ring rolling was established based on software Deform-3D,the process of radial-axial rolling of TC4 titanium alloy ring was simulated and analyzed.The results indicate that the metal flow curve wavily fluctuates,the flow speed of outer-plane metal is greater than that of inner-plane me…
A novel amphiphile containing two functional groups of both quinolinium and boronic acid,N-(boronobenzyl)-8-hexadecyloxyquinolinium bromide(BHQB),was synthesized.Scanning electron microscopy(SEM) indicated the formation of bilayer vesicles in the methanol/water solution(φ=0.5).Differential scanning calorimrtry(DSC) es…
The preparation of polyurea composites filled with amine-functionalized multiwalled carbon nanotobes(MWNTs) is described.First,MWNTs were oxidized in mixed acid to generate hydroxyl groups on their surfaces.Then,polyacrylic acid was covalently grafted onto the surface of the MWNTs through esterification of polyacrylic…
Taking TIG + high-purity argon as protective gas welding method to link the zirconium R60702 plate at different protection temperatures,and using electrochemical corrosion and the morphology observation of optical microscope,R60702 corrosion behavior in acetic acid was studied.The results showed that in 5 mol/L acetic…
In order to prepare for high performance large size anode-supported planar solid oxide fuel cell(SOFC) and avoid the gas distribution difference during the test,in this research single cell with dimension of 10cm×10cm(active reaction area of 9cm×9cm) was divided into 9 galvanically separated segments(each segment with…
To study the separation and purification of polysaccharide of mulberry by strong alkalinity ion-exchange fiber on the dynamic conditions,the influences of velocity,pH value,concentration and volume of the polysaccharide solution on dynamic adsorption and desorption were investigated respectively and the dynamic adsorp…
With complex composition,large output and harmful impact,heavy metal sludge of cold-rolled stainless steel has been a focus of environmental treatment in stainless steel enterprises.At present,there is no proper,safe,economical and practical utilization method both home and abroad.Aiming at the sources and characteris…
Lithium orthosilicate(Li4SiO4) pebbles are considered as the candidate tritium breeders of Chinese helium cooled solid breeder test blanket module(CH HCSB TBM).The post-irradiation annealing experiments of lithium orthosilicate ceramic pebbles,made by freezen-sintering process,have been performed in CAEP.The samples w…
Thermal simulation on rolling of TZM alloy slab produced by PM was researched using Gleeble-1500 thermal-mechanical simulator.The testing programs were performed using rectangular sample with the size of 10 mm×15 mm×20 mm at 1150-1300 ℃,the deformation degree of 50% and the deformation rate at 1,3,5 s-1 respectively.T…
The antiphlogistic part of the barks of Streblus asper was investigated through pharmacological experiments.Through the use of chromatographic technology,seven compounds were isolated from the antiphlogistic part of,and their structures were identified by spectroscopic analyses,especially NMR.They are:succinic acid(1)…
Achieving macromolecular chain ambient cross-linking to form a network structure in acrylic resin leather coating process is a kind of currently widely adopted technical ideas and methods.Its mechanism and modes are also a hot topic in the current research field of acrylic resin emulsion preparation.This paper reviews…
