Based on the literature research, the types、applications and main defects of common plasticizer is described. Then the types、applications of some the secure environment-friendly plasticizer, such as ester plasticizer and citric acid ester plasticizers case studies and were reviewed.
The developing progress of flame retardancy of extruded polystyrene foams(XPS)was reviewed. Mechanism of flame retarded XPS foam was discussed,especially using hexabromocyclododecane(HBCD)as a flame retardant.Influencing factors on flame retardancy of HBCD were also analyzed.Finally,the developing trend of flame retar…
Bi-compensated( 0. 84- x) Na0. 5Bi0. 5TiO3-0. 16K0. 5Bi0. 5TiO3- x SrTiO3( abbreviated as NBT-KBT-xST) leadfree piezoelectric ceramics were prepared by solid-state reactions. The effects of SrTiO3dopants on the structure and electrical properties of ceramic samples were investigated. The results indicated that solid s…
In order to study the photocatalytic degradation of benzene series, PW/Ti O2 composite catalyst was prepared by sol-gel method and characterized by BET,XRD and SEM. Photocatalytic performance and mechanism of composite catalysts were investigated with benzene as test compound. The results showed that PW/Ti O2 was anat…
GH907 material has high strength,low thermal expansion coefficient and good thermal fatigue performance,but when it works in high temperature environment for long time,serious corrosion will occur.To make this kind of material have good application to high-tech fields such as aviation,aerospace and shipbuilding,a kind…
The surface of a glassy carbon electrode(GCE) was modified with graphene(Gr) and histidine(His) to evaluate the electrochemical response of the modified glassy carbon electrode to troxerutin hydrolysate.The results suggest that the modified electrodes are useful for constructing electrochemical sensors.Under the optim…
This study was about the surface modification of PP separator by introducing crosslinked divinylbenzene(DVB) /methyl acrylate(MA) to increase its thermal dimensional stability.The total reflection Fourier transform infrared spectroscopy(ATR-FT-IR) was used to prove that the copolymerization of DVB and MA did occur on…
Effects of cooling process on microstructure and mechanical properties of low carbon Mn-Mo-Nb-Cr-Ni series Q800E grade construction machinery steel were studied using high density laminar cooling device. The cooling rate and final cooling temperature were the main control parameters. The results indicate that the stre…
In recent years,with the development of the research on organic-inorganic nano-hybrid materials,the use of inorganic nano powder as the filler synthetising the polyurethane composites was poplar and the properties of composites were improved.Nano-silica has many advantages,such as small grain size,big specific surface…
Because the difference between the acceleration curve of traditional projectile structure and the measured acceleration curve is large,refining projectile structure is proposed. After setting up multi-storey concrete target board penetrated by the projectiles with different structures,the simulations with traditional…
The mechanisms and influencing factors of elemental sulfur formation have been elaborated and analyzed. The prediction methods for elemental sulfur formation have been presented. Based on the geothermal steam parameters and steam turbine operating data from a typical wellhead pow- er plant located at Olkaria in Kenya,…
Due to high production energy consumption in copper smelting enterprises, energy saving and consumption reduction are important ways to reduce the cost and increase efficiency for the enterprises. In recent years, Jinlong Copper Co., Ltd has developed research on integrated energy saving and energy optimization by coo…
The order of catalytic activity of organic acids for hydrolysis of cellooligosaccharides is oxalic acidmaleic acidmalonic acidacetic acidformic acidbutanedioic acid. Butanedioic acid could not catalyze the hydrolysis of cellooligosaccharides. The catalytic activity of biatomic acids is relative to their acidity. The a…
Effects of Si content on microstructure and mechanical properties of Mg-4Al-1Zn-xSi(x = 0.5,1.0,2.0,mass%) alloys were investigated by optical microscope(OM),scanning electron microscopy(SEM),X-ray diffraction(XRD) and tensile tests.The results show that the network β-Mg17Al12 phase is continously distributed on grain…
The polyvinylidene fluoride /carbon black( PVDF /CB) composites were fabricated in this work. The effects of CB particle composition and layered assembly of PVDF and PVDF /CB on the electromagnetic shielding properties had been performed. The results indicated that the shielding effectiveness(SE) was gradually enhance…
Based on the analysis of temperature effect and aging characteristics of cable insulation parameters,it can be concluded that the dielectric loss of high voltage mining cable should not be neglected,and therefore an assessment method for the temperature rise of the mining XLPE cable in service considering the aging fa…
The effects of curing agent and curing additive on the vulcanization characteristics and mechanical properties of F246 fluororubber were investigated.The results showed that with the increasing of curing agent double-25,the t90 shortened,the minimum and the maximum torque increased,the tensile strength increased first…
Composite magnetic material was prepared by ultrasonic enhancement/hydrothermal method,the preparation of the ferrite magnetic material accumulated data,graphite sheet uniformly loaded on BaFe12O19nanoparticles,forming good complex.And the prepared magnetic coercivity,saturation magnetization,residual magnetization of…
The effects of heating temperature and holding time on microstructure of 22MnB5 were observed by OM, and tensile strength and hardness of the specimens were tested. The results show that: the steel is full of martensite after heated at temperature higher than 860 ℃. But the tensile strength and hardness decrease with…
Hot compression tests of 7056 aluminium alloy were operated on Gleeble-1500 thermal simulator at a strain rate of 0.01-10s-1 and a temperature from 300 ℃to 450 ℃.The microstructures of hot deformed alloy were observed by metallographic microscopy to research the effect of temperature on microstructure evolution of 705…
