The spin solutions of PVA/SiO2-TiO2 hybrid materials were prepared by sol-gel method with tetraethoxysilane(TEOS),tetrabutyl titanate(TBT)and poly(vinyl alcohol)(PVA),then fiber membranes were obtained by electrospinning.FTIR results show that hydroxyl in PVA condenses with hydroxyl of hydrolyzing TEOS and TBT;the hyb…
This paper introduces the composition and structure characteristics of collagen and the extensive application of collagen in food industry,such as healthy food,meat product improvers,food package materials,food coating materials and so on.Furthermore,the future prospect of collagen in food industry is viewed.
1.25 MeV γ-ray of 60Co Compton scattering coefficient in the simple of paraffin,are measured by γ-ray energy spectrum analysis in two determining means.At the same experimental condition,we have used this scattering coefficient to determining grease thickness simulated by paraffin.The result show the average relative…
Europium ternary complex Eu2L3Phen·4H2O with luminescent properties was synthesized by the reaction of the unsaturated dicarboxylic acid 3-hexene acid(H2L)with 1,10-phenanthroline(Phen)and the EuCl3.The photoluminescence properties of the doping polymer materials were researched after the europium complex was doped to…
By using needle-plank gap to produce the severe non-uniform field and generate steady corona discharge under certain voltage,the relationships between the number of UV photons,instrument gain and photograph distance were studied in this paper.Then the simulation experiments about faulty insulator,contamination insulat…
The deformation of the first cutting deformation zone was introduced in machining of SiC reinforced aluminum composites, and the formula of SiC reorientation was induced. What is more, the phenomenon of the reorientation of SiC reinforcements in the first cutting zone was supported by the experimental results. The res…
Using integral formula of diffusion equation of heat quantity based on the third boundary condition and one-dimension-half-space,the analytical solution of diffusion equation of one-stage or two-phase carbonizing(nitriding)was derived,respectively,for two initial conditions,with or without pre-carbonizing.Through math…
The influence of heating temperature on morphology of eutectic carbide and impact fatigue property of low alloy wear resistant cast iron were studied by OM, SEM and impact fatigue tester. The results show that the network eutectic carbides are broken and blocks carbides are increased gradually with increasing of heati…
Polythiophene sensitized TiO2(PTh/TiO2) composite materials with different n(Th)/n(TiO2) were synthesized by the in situ chemical oxidation polymerization using FeCl3 as an oxidant in CHCl3.TEM,FTIR,XRD,DRS and PL were used to characterize the composite materials and their photocatalytic activities were investigated b…
Four kinds of gloss-reducing agents were introduced into PC/ABS blends used for inner decorative articles of automobiles.The effects of these agents on gloss reducing and mechanical properties of the blends were compared.It was found that all the four were effective in gloss-reducing.BMAT was harmful to the impact str…
Al2O3/Fe surface composites were formed on steel pipe by combustion synthesis.The micrographs,phase composition and redistribution of elements were observed and investigated by means of microscope,X-ray diffraction and EMPA.The results show that the coating consists of α-Al2O3,FeO.Al2O3,Y3Al5O12 and a little 3Al2O3.2S…
From hydration product,combined water amount,microstructure and product strength,reaction characteristics of ceramic polishing waste(CPW)-lime system was studied at room temperature curing and autoclaved curing by contrast with fly ash(FA)-lime system that is used widely in industry.XRD,SEM,ICP-AES and FTIR were used…
Prior to the melt-compounding fabrication of the desired multiple-walled carbon nanotubes/poly(ethylene eterephthalate)(MWCNTs/PET)nanocomposites samples with MWCNTs loadings ranged from 0.2% to 2.0%(mass ratio,hereinafter the same).MWCNTs/PET masterbatch comprising of 10% of MWCNTs was prepared with phenol/1,1,2,2-te…
The surface acidity of ZrO2 catalyst was determined by Hammett indicator method.Effect of preparation condition on the surface acidity of ZrO2 was studied.Acid feature characterization results show that the calcination has little effect on surface acidity,but the total amount of acid sites on ZrO2 will be decreased,wi…
The powder recycling from the waste printed circuit board was used to prepare BMC as filler by the method of compression molding.By orthogonal test,the optimal ratio of unsaturated polyester resins,glass fiber and waste printed circuit board powder in BMC was determined,and effects of content of resin,filler and glass…
The two-dimensional steady gas-liquid two-phase flow in cavitation reactor with taper throttle was numerically simulated.By using pressure difference,velocity and volume fraction of vapor as weighed criterion,the distribution situation of flow field and the difference of cavitation characteristics were analyzed in the…
The effects of hydrogen/electron dual-beam irradiation on the stability of oxide particles of a new 12Cr-ODS ferrite steel made by chemical socking method was studied in this paper.The observation of the microstructure of oxide particles under different irradiation doses show that,before irradiation and after an irrad…
The self-developed new type ADVANS 450W martensitic wear resistant steel was heated to 900, 1 050 and 1 200 ℃ for 30 min for austenization respectively,then oil quenched and tempered at 300 ℃ for 2 h,then aircooled.The impact abrasive wear resistance of the steel relative to high manganese steel ZGMn13 was investigate…
