With SBS(styrene-butadiene-styrene block copolymer) elastomer as matrix resin for hot melt PSA(pressure sensitive adhesive),so the PSA’s initial tack was tested by Loop Tack method and incline rolling ball method.The influences of some factors(such as bonding layer thickness,PSA’s storage modulus and adherend type) on…
Catalyzing and oxidating NO2 in the air with nano-TiO2 carried by mortar is affected by environmental factors.By using different experimental methods,the influence of UV light intensity on the concentration of NO2 is investigated,and the effects of UV light intensity and test temperature on catalyzing and oxidating of…
Experimental study on the influences of water vapor content on selective non-catalytic reduction(SNCR) using ammonia gas was carried out in a quartz tube reactor.The experimental results show that when the water vapor content increases:the optimum NOx reduction temperature and the NOx reduction temperature window both…
This thesis analyzed the effect of ultrasonic extraction for curcumin and discussed the dyeing condition for curcumin on silk. The results showed that optimum extracted effect of curcumin was obtained in such condition: 75 % ethanol as extractant 1∶30 bath ratio 360 W ultrasonic power and 60 min ultrasonic time; this…
The streaming potential of saturated solution of L-Trp was determined to characterize its crystallization in temperature lowering process.The influence of solution acidity and the initial temperature to the v-t curve was investigated.The results showed that the L-Trp solution had more competitive nucleating ability at…
To take further the advantage of the solute-rich surface layer of twin-roll cast high-P steel strip,the causes for the formation of the P-rich surface layer were discussed.Experimental results indicated that there will be a P-rich layer nearby the surface of the higher-P strip after controlling the processing paramete…
This paper used nano-Al(OH)3 and nano-Zr(OH)4,which were prepared by secondary nano self-assembly as raw materials,to prepare nano-ZrO2 solid catalyst by squash method and extruding method.The catalysts were characterized by BET,SEM and so on.The influence of different preparing method to the structure and property of…
The 21st century mankind is faced with an energy shortage and worsening environmental crisis. With the number of vehicles within the exciton and increasing consumption of petroleum resources, the contradiction between oil supply and demand growing, the lack of oil resources in China, both from the political and econom…
The effect of nano palygorskite dispersion process on the friction properties of lubricants was researched.The results show that the three dispersive processes all can disperse homogeneously the nano palygorskite into the base oil.Put it aside at room temperature for 24 hours,a little deposition appears in the second…
The growth rate of iminodiacetonitrile in the continuous cooling crystallizers basically obeys ΔL law when the particle size is greater than 100 μm,but deviates from ΔL law when the particle size is smaller than 100 μm.The growth of iminodiacetonitrile in crystalline process is size-dependent.The experimental data of…
Cu2+-ZnO/cetylpyridinium-montmorillonite(CZCM) was prepared by using Cu2+,Zn2+,cetylpyridinium(CP),and montmorillonite(MMT).The structure,characteristic,and antibacterial activity of CZCM were comparatively investigated.The results show that zinc ion is added in the MMT suspension at an amount of 0.75 times the cation…
By using plasma to modify the surface of starch films,the acrylic-acid grafting ratio(AGR) of the modified starch was measured,and the plasma discharge power,discharge air pressure,discharge time and laying time after discharge for the modified effect of starch films were analyzed. The experimental results showed that…
The polyacrylonitrile(PAN)-based fibers are carbonized at temperature of 600~900℃.Chemical composition and microstructure of the fibers are characterized using elemental analyzer,wide-angle X-ray diffractometer and laser Raman spectrometer.Mechanical and electrical properties of the fibers are examined.The results ind…
According to chemical intumescent flame retardant mechanism,TPO flame retardant composites were designed with TPO as matrix.The properties of TPO chemical intumescent flame retardant and the structure of char layer were studied.ADP improves the LOI and the grade of vertical burning test.When ADP were up to 70 phr,LOI…
New style nickel hydroxide materials were prepared by chemical precipitation of cobalt,zinc,calcium,magnesium,copper,manganese and nickel elements followed by decorating or dopping.Charge-discharge properties were analyzed by galvanostatic charge-discharge cycling technology on conditions of different temperature and…
Warm compaction was applied to prepare bonded NdFeB magnets.Warm compaction was proved to be a good way to improve the density and magnetic properties of bonded magnets.Studies show that the result of warm compaction is closely related with temperature and pressure.And softening point,viscosity and solidifying point o…
Transport properties of two types of cross-junctions in graphene nanoribbons are investigated by using the tight-binding model.A simple junction is formed by an armchair graphene nanoribbon crossing with a zigzag graphene nanoribbon.A deformed junction is constructed by adding graphene triangle flakes to the corners o…
Functionally gradient materials(FGM) are heterogeneous material.For this,its characterization methods are very different from those of homogeneous materials.In this paper,practical characterization techniques for FGM,such as microscope,thermal analysis,spectrum,energy spectrum,elemental analysis,X-ray diffraction,elec…
AZ31 magnesium alloy sheets were prepared by multi-pass equal channel angular rolling(multi-pass ECAR).The microstructure,texture and tensile properties were investigated.The results have shown that the grains in the sheets are processed alternatively with refined and coarse multi-pass ECAR,which has a great effect on…
Submicron fiber or nanofiber from brown cotton fiber cellulose solution in LiCl/DMAc system is prepared through electrospinning and subsepuent freezing treatment via methanol/water(9/1) solution.It is found that fusion can be reduced more after treatment via methanol/water(9/1) solution at 258K,and the diameter of ele…
