The continuous separation technology of dietary fiber and its components from soybean was studied in this paper. Results showed that the optimum conditions for extracting dietary fiber from soybean by chemical-enzyme method were papain 0.012g/g,pH12.03,temperature 68℃. Under this condition,the contents of TDF,SDF and…
The hyperbranched polyurethane acrylates(HBPUA)were prepared by terminal hydroxyl modification of hyperbranched polyester using synthesized 2,4-toluene diisocyanate hydroxypropyl acrylate(TDI·HPA)monomers.The effect of reaction temperature and time on the free-NCO contents of the products were studied.The active monom…
Using the radio frequency reactive magnetron sputtering technique,ZnO and Al-dopped ZnO thin films were fabricated on glass substrate by changing the Ar/O2 ratio and substrate temperature.The film crystallinity,optical properties and surface morphology were investigated by X-ray diffraction,UV-visible spectrophotomete…
Organized mesoporous alumina(OMA) was synthesized by the inexpensive aluminum nitrate,PEG1540 was used as template,ammonium carbonate as precipitating agent.CO2 sorbent were prepared by introducing(3-Aminopropy)triethoxysilane(APTES) into OMA type using a post-synthetic impregnation method.The synthesized sorbent was…
High density polyethylene was flame retarded with single molecular intumescent flame retardant melamine salt of pentaerythritol phosphate(MPPL) and mixed intumescent system melamine phosphate(MP)/pentaerythritol(PEL),and the corresponding performances of flame retandant materials were compared.It was showed that the s…
To acquire basic information about proteins associated with flossy cocoon mutation in silkworm(Bombyx mori),two-dimensional electrophoresis(2-DE) was carried out to analyze proteins from various sections of silk gland of the 5th instar larvae of 3 silkworm strains with different cocooning characters(i.e.,normal cocoon…
In Tahe Oilfield,the inter-station accompanying gas pipeline have high contents of H2S.If the pipeline is corroded,the environment will be polluted and people will be hurt,so the accompanying gas pipeline is evaluated.The evaluation result shows,under present operation condition and corrosion environment,the pipeline…
The deformation fracture behavior under impact load of 6061 aluminum alloy has been tested using common drop hammer impact test machine and self-designed fixture tool.The results show that the fracture behavior of 6061 aluminum alloy under both of impact loading and sub-static tensile are no obvious change.The fractur…
Two new organic crystals of 2,8-bisthienyldibenzothiophene(BTDT) and 2,8-bis-dithienyldibenzothiophene(BDTDT) compounds were successfully obtained.The change of end-capped group from thiophene to dithiophene causes big differences in molecular packing and carrier-transport property.The adjacent molecules of compound B…
The tensile strength of AM60B magnesium alloy die casting part can reach to 176 N/mm2 while the magnesium alloy part being produced with semi-solid die casting technology,that means the solid fraction is about 50% and the die casting speed is 3 m/s.In addition to chemical composition,microstructure and alloy phase ori…
The reuse of uranium and plutonium from high temperature gas-cooled reactor(HTGR) spent fuel will improve resource usage and minimize waste.The characteristics of different closed fuel cycles were studied here for uranium and plutonium recycled from 250 MWth high-temperature gas-cooled reactor pebble-bed-module(HTR-PM…
p-toluenesulfonyl chloride is used as phenolic resin curing accelerator,the curing kinetics of p-toluenesulfonyl chloride/phenol formaldehyde resin is studied by differential scanning calorimetry(DSC).The curing reaction with different levels of p-toluenesulfonamide chloride/ phenol formaldehyde resin system is analyz…
The content of research is developing a magnetic system with a uniform and high magnetic field in the air gap.It consisted of a series of sector Nd-Fe-B.Magnetization direction of the magnets changes along the circumference,forming two poles perpendicular to the axis.The magnetic system is layered along the axis,with…
White speckle filament and white segment filament are researched in viscose filament in this paper.The JSM-6490LV SEM of JEOL company is used to characterize the surface morphology and cross-section structure of the sample.The results show that the white speckle filaments in viscose filament are bend and impure in pro…
The hot deformation behavior and microstructure evolution of 316LN stainless steel were investigated at 800-1200 ℃,under the strain rate of 0.01-10 s-1,with reduction up to 0.91 by hot constant tests on a Gleeble-1500D thermal simulation testing machine.The results show that there is no peak stress on the true stress-…
A novel sterically hindered phenol derivative was produced as a lubricant additive.Thermogravimetry analysis(TG) indicates that this additive has higher thermal stability than commonly used phenolic antioxidant.The antioxidation property of the product was tested by adopting rotary bomb oxidation test(RBOT),and pressu…
