As the stirring flocculant blender shaft and Planet-cycloid reducer output shaft coupling with rigid links,but when flocculant viscosity greater mixing,stirring,flocculation Breeze leaf led forces and not rotating Uniform,resulting in persistent reducer gear damage and stirring shaft bending phenomena.In response to t…
The effect of aging time on microstructure and mechanical properties of a new type of ZW21 magnesium alloy was investigated by using metallographic microscope,SEM,XRD and electronic universal material tesing machine.The results show that,after solution treating at 525 ℃ for 4 h and subsequently aging at 250 ℃,the peta…
Through coupling of finite element and cellular automaton method,a CA-FE model was established to simulate the solidification structures of Al-Si alloy at different casting conditions,and the simulated results was validated with hot test. The results show that the simulated results are in good accordance with the expe…
The chemical composition, particle size distribution, real density, bulk density, drying and fluidity performance of carbide slag powder were studied. The presenting result might be used for the application of carbide slag for the PC kiln process design, equipments selection and operation optimization.
A novel glucose biosensor was fabricated by means of crosslinking method to immobilize glucose oxidase(GOD).Neutral red(NR) was electorpolymerized on glassy carbon(GC) electrode modified with nafion to form NR/nafion/GC electrode,then GOD was immobilized on the above electrode by a cross-linker of glutaraldehyde.Lastl…

Micro-electrolysis/SBR process was used to treat production wastewater from a tannery in Jinjiang.The results show that the COD removal efficiency by micro-electrolysis under the acidic condition is better than that under alkaline condition,and the COD removal efficiency by cast iron/activated carbon filler is better…
Based on the innovated technique of milk waste bags recycling,the paper mill relizes the recycling of unde-gradable wastes;analyzes the problems met in expanding reproduction in enterprise;puts forward countermeasures.
The effective use of transform catalyst during the methanol production is discussed in this article from the catalyst loading, oxidation, deoxidization, etc.
GZO/Ag/GZO three-layer films were prepared on glass substrates by radio frequency magnetron sputtering of GZO layers and ion beam sputtering of Ag layers at room temperature. The effects of vacuum annealing temperature on the structural,optical and electrical properties of GZO/Ag/GZO three-layer films were investigate…
Experimental study of SNCR process with urea as reducing agent and Na2CO3 as additive was carried out and detail analysis of different compositions of NOx was given out. In the temperature range of 800～975 ℃, the components of NO decreases at first and then increases, while the component of N2O increase at first and t…
Cr-doping ZnO thin films with c-axis preferred orientation were prepared on glass substrates by magne-tron sputtering at different substrate temperatures.Effect of the substrate temperatures on the structural and optical characteristic of Cr-doping ZnO thin films was studied by X-ray diffraction(XRD),scanning electron…
Composite coating, as a substitution of traditional induction hardening on the surface of medium carbon steel, was prepared onthe surface of the low carbon steel process roll with a big-diameter on the production line for hot-dip galvanizing by making use of overlay welding and spraying of hardalloy materials. The mat…
To deal with the problems of bad absorption,static and difficult to card of refined silk fiber,hydrophilic modification of raw silk was done and a contrast analysis of the web forming before and after the modification as well as the quality of the spun-laced none-wovens were carried out.The result shows that the hydro…
