The highly dispersive fine spherical silver powders with the diameters ranging from 0.7 to 2.5 μm were prepared by reducing AgNO3solution with polyvinylpyrrolidone(PVP)as protective agent,polyoxyethy-lene-sorbitan20-monooleate(Tween-80)as surfactant and ascorbic acid as reducing agent. X-ray diffractometry(XRD)and sca…
The free radical copolymerization of acrylonitrile( AN) and itaconic acid( IA) was investigated in the mixed solvent system of dimethyl sulfoxide( DMSO) and dimethylacetamide( DMAc). The chemical structure and composition of the polymers were analyzed by Fourier transform infrared spectroscopy( FTIR) and elemental ana…

To further reduce the energy consumption of CO2 capture in IGCC system, based on the oxy-fuel combustion method, a zero CO2 emission integrated gasification combined cycle(IGCC) system with low energy consumption integrated with the oxygen transport membrane(OTM) was studied. By utilizing the Aspen Plus software, this…
The quasi-superplasticity of the cast AZ80 A magnesium alloy was studied through high temperature tensile experiments.The results show that the cast AZ80 A magnesium alloy has bigger elongation(as much as 260%)under certain conditions.At the same time,the broken specimens have no obvious necking constriction,and its s…
Partial nitrification was researched in SBR under limited oxygen condition to produce the correct influent for the ANAMMOX process,which was fed with effluent of biological fluidized bed for acrylic fiber wastewater. The main parameters of the reactor were controlled as follows: DO was 0. 30 to0. 40 mg /L,pH value was…
Based on relevant actual production practi ce, the centrifugal casting-forming process and heat treatment process for the bimetal composite roll are described. The superiorities of the said roll-casting process are analyzed. And the application result of the centrifugally-cast composite roll is compared with those of…
