Thermal decomposition of aluminum methyl cyclohexyl hypophosphite(Al(MHP)) filled epoxy(EP)composite were investigated with thermogravimetric analyses(TG)and fourier transform infrared spectroscopy(FTIR).The interaction between component during thermal decom position process was explored with theoretical arithmetic,ad…
The strength and energy absorption parameters of the anticollision beam of a steel bumper are obtained by three-point static pressure test and simulation.After that material substitution is carried out and a new aluminum alloy beam is designed by structure optimization method based on the performance of the steel beam…
In this article,preparing conditions of active carbon using zinc method were studied using the bamboo as material,the Methylene blue decoloring force as inspection indefor.On the basis of single factor experiment,using the orthogonal design,the factors such as material ratio,activation time,activation temperature were…
According to consult a number of foreign patents and papers,the properties,applications and preparation methods of special PVC resins are summarized.There are four types of special PVC resins as follows: ① the special PVC resins,which are prepared only from vinyl chloride through different granulating courses or under…
The material was prepared that mixing LDPE and nano-CaCO3or nano-SiO2that was surface treatment by extruding and blowing. The performance of interaction between inorganic nano fillers and the polymer in the aging process of the composite,and the influence of surface treatment of inorganic nano fillers on their interac…
Influence of Li pre-doping on the performance of lithium ion capacitors(LIC)were investigated.The optimized procedure was suggested according to experiments.Pre-doping potential at 0.05Vgave the best performance on LIC with the method of short circuiting.More lithium ion was intercalated into the negative electrode wi…
A bench scale experiment was conducted to investigate low intensity ultrasound(LIU),which was effectively increase microorganisms activities,in treating the salt-tolerant quinine-reducing(STQR) consortium under saline condition(NaCl conc.50 g/L).Effect of quinine-mediated bio-degradation of azo dye at irradiation freq…
Based on a seed decomposing tank structure detection of concrete foundation,it's realized that industrial aluminum hydroxide preparation of groove in serous load increases and the structure of the material for corrosion causes of slot concrete infrastructure pose a safety hazard.Through a seed decomposing tank of the…
Minimal inhibitory concentration(MIC) and minimal bactericidal concentration(MBC) of chitosan to Staphylococcus aureus(St.aureus),Escherichia coli(E.coli),Pseudomonas aeruginosa(P.aeruginosa) and Candida albicans(M.albicans) were determined by using the tube dilution method.The bactericidal rate of chitosan and lysozy…
In order to optimize the schedule of multi-pass hot rolling process of shape metal, effects of rolling parameters on the section size and microstructure evolution were investigated. Based on microstructure evolution equations available in literatures, a set of mathematic equations were reproduced to model the evolutio…
The finish turning experiment of AZ91D magnesium alloy was carried out at different cutting speeds,and the breaking performance and shape of chips and surface quality of workpiecr at different process parameters were compared.The results show that,at the premise of constant cutting depth,with the increase of cutting s…
The dilution renaturation method was applied to obtain active Onconase from inclusion and compared with the traditional acetic acid sinking method.The effects of renaturation temperature,urea concentration and addition time of GSSG on renaturation efficiency were explored.The results showed that,the Onconase content a…
Crystallization behavior and morphology of PPR induced by TMB-5 were investigated by wide-angle X-ray diffraction(WXRD),differential scanning calorimetry(DSC) and polarizing optical microscope(PLM).The mechanical properties were also tested.The results showed that the crystallization peaks rise from 102.4 ℃ to 109.3 ℃…
In process of various kinds of unexpected incidents,the fragments of explosive anti-riots munitions may cause fatal injure.Based on the force analysis of the fragment in its flying course,this study developed the motion equation for fragments of explosive anti-riots,calculated and analyzed the impacts on the fragments…
The 11Li2O-3Nb2O5-12TiO2(LNT) microwave dielectric ceramic composites have been prepared by the solid-state reaction method. The effects of the sintering temperature on phase structure and properties were investigated by XRD, SEM and the measured dielectric properties. The calcined powders at 850˚C and the dense ceram…
The dynamic mechanical response of three-dimensional (3-D) braided fabric reinforced composite under transverse impact was tested with modified split Hopkinson bar. The experimental results showed that the peak load increased with the increase of impact velocity. Based on the fracture morphologies of 3-D braided fabri…
