The CE/nano-SiO2 composites were made by molding method.The effects of nano-SiO2 and its surface treatment on the toughness and wear properties of the CE/nano-SiO2 composite were investigated by impact strength test,wear rate test and characterization of TEM and SEM.The result showed that the nano-SiO2 treated with co…
The Ti-deoxidized products which was widely studied in the field of oxides metallurgy was taken as an example.The research method of superfine inclusion especially the method of studying inner structure and phase composition was discussed by means of observation of metallograhic specimen and inclusion from electrolyzi…
The colored yarn with fine denier and low linear density was produced in high speed spinning machine.The experiments were carried out mainly on chip drying,spinning,spinneret design,spin pack assembling and draw-winding.The 27.5 dtex/24 f fine denier environment friendly colored polyester FDY was manufactured successf…
Purpose:To investigate the metabolic changes of bilateral hipppocampi in patients with Alzheimer's disease(AD) by high field proton magnetic resonance spectroscopy(1H-MRS).Methods: T1WI-3D scan and three dimensional MPR reconstruction of hippocampus were used in 14 patients with AD and 10 normal controls to ensure acc…
Winding deformation is one of the most common faults of power transformers.It may cause partial discharge,even leads to insulation breakdown.Winding deformation also may cause the declining of mechanical properties of winding.The study of high sensitive detection method has important significance in detecting minimal…
For studying the influence on underground supporting structure of conventional penetrated bomb explosion in the rock.Dynamic responses of anchor shotcreting support structure of underground protective engineering were studied using LS-DYNA in the rock explosion.The reinforcement of bolt in the rock was taken into cons…
The system is completely driven by solar energy for splitting CO2to fuel features a perfectly recycling Solar-CO2-Fuel device.The carbonates are used for the electrolyte operated in a high temperature.In this paper,the SPET theory of the system iss briefly analyzed.Based on the electrochemical reactions in the high te…
Mechanism and performance of staple combing elastic nonwovens are explored in the paper.Application of this kind of product is prospected.
Ni/γ-Al2O3 catalyst with 17% nickel loading was prepared by impregnation method.The Ni/γ-Al2O3 catalyst was treated under hydrothermal condition for different time at 180 ℃ and 4 MPa H2 pressure.The structure of the fresh and treated Ni/γ-Al2O3 catalysts were characterized by XRD、 TG、 H2-TPR and N2 physisorption.The e…
The modified NBR-based sealant was prepared using nitrile rubber(NBR) as the main raw material by compounding with chlorinated polyethylene(CM),filler,phenolic resin,modified silica and mixed solvent etc.in a certain propotion.We investigated the effects of NBR brands,compatibility and mixing ratio of NBR to CM,phenol…
TiHfx(x=0.13,0.26,0.52,1.03) is prepared on electromagnetic levitation melting system for enhancing the ability of hydrogen storage in the titanium metal.The homogeneity of the alloys is proven by ICP-AES analysis,but the proportion of the titanium in the alloys is 0.6%~2.6% less than the added amount because the tita…
The re-crystallization rule of SWRH82B steel at high-temperature, more rolling times and high deformation rate was studied. The results indicate that, with the increase of rolling times, the grain size becomes smaller, the content of sorbite multiplicates, and the yield strength improves.
Blended 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) with diphenylmethane diamine-based benzoxazine(BOZ-MDA),resin casts were prepared after curing.Properties of the casts were investigated by differential scanning calorimetry (DSC),dynamic mechanics analysis (DMA),vertical burning test,thermo gravimetric…
The test method of down-proof property of fabric is that making a certain size bag with sample fabric and down material filled and counting the downs out of the fabric through simulation test,and then evaluating the down-proof property of the fabric.In this article are studied the test results from five different fabr…
The design of ROCOS compact spinning device,its spinning principle and application scope are analyzed with the formed yarn quality spun by magnetic compact spinning and normal ring spinning tested and compared.The result shows that ROCOS is an excellent compact spinning device producing good quality yarn with small in…
This paper studied foaming behavior of PS micro-foaming sample at different mold temperature by a self designed mold.It revealed the real reason for the growing of the cell average diameter with the elevation of mold temperature,the results showed not because of the mold temperature increasing so that melt temperature…
The advanced processing and equipment characteristics of Baosteel 1220 new electrolytic tin line were introduced. The difference between conduction reflow and induction reflow,and the temperature control curve of combined reflow were investigated emphatically. Combined reflow combines the advantages of conduction refl…
The high-speed cutting processing is one of the main development directions of advanced manufacture technique.High-speed motorized spindle is the key component of high-speed machine.The thermal conditions of the main motor of high-speed motorized spindle are poor,If the temperature of bearing is too high,the precision…
In order to debase viscosity of soy-based protein adhesives,enhance bonding strength after boiling resistance test of plywoods and meet industrialized production requirement,so the tradition soy-based protein adhesives were modified.The optimal contents of modifier were established by thermal analysis results and test…
The wear of rail—shape groove of BD mill of universal rolling line of Pangang was serious.One set roll could be only used two times if it was machined fully at the time of machining.The roll using life could be increased to 4~5 times when using the spreading machining method for the rail head and tail.However,the meta…
