Tritium can be released from the exterior of tritium-contaminated stainless steel by slight stirring while decontaminating and disassembling. In order to avoid secondary tritium contamination to environment and operators,it is necessary to cover with an effective coating to tritium on the exterior of tritium-contamina…
This paper introduces the sulfur-resistant partial CO shift process adopted by Xinneng Fenghuang Tengzhou Energy Co.Ltd in 360 kt/a methanol plant,reviews the sulfurated process of QDB-03 catalyst and operation conditions of CO shift system,discusses the problems exposed in trial operation and measures against them.
Tribological properties of FB resin,YSM resin and ALPF resin matrix composites had been studied.The results indicated that FB resin matrix composite had the best performance.The favorable mold-temperature of FB resin was about 170 ℃,at the condition,specimens had low special wear and relative high friction coefficient…
This paper prepared n-HA/NRL composite membrane,using different modifier of nano-hydroxyapatite(n-HA)and natural rubber latex(NRL)compound.Then,this membrane was characterized by IR,TEM and SEM.The results showed that n-HA was about 20～60nm in particle size,and around 2.5～3.5 in aspect ratio,while this membrane's stru…
A method to improve electrical conductivity of carbon nanotube(CNT) networks by ion implantation is reported in this paper.MWCNT networks were prepared by a spray coating method,and were implanted with 70 keV Ar+ ions.The electrical conductivity increased by ～80% for the MWCNT networks irradiated to 2×1016/cm2 at 800…
Ni-based alloy coating was prepared by hot dipping on Q235 steel.Before and after corrosion,the phases and the microstructures of the coating were investigated by XRD and SEM-EDS,respectively,and the mechanism of corrosion of the coating was discussed.The results show that there are many forms of the precipitates in t…
This paper stated the development of high speed steel and process of steel roll through introducing the process and heat treatment technic,the influence of different quenching temperature to hardness,grain size degree,it gives the quideling of anfiming the heat tkeatmunt of hiqh speed sted rou
When a test of axial force has been carried out in a 2200mm aluminum foil four-high mill,it is found that the roll system is not in a stable position in the 1mm gap distance of roll system pair and a micro-scale dynamic cross behavior happened between the work roll and the back-up roll.So an abnormal overloaded axial…
The determination of trace Cr6+ in waters is very important because of its highly carcinogenic and mutagenic effects.In this study,gold nanoparticles(AuNPs) with average diameter of 16 nm were synthesized with the citrate-mediated reduction of HAuCl4 and modified by 1,4-dithiothreitol(DTT) containing two end thiols to…
First a hydroxy-terminated unsaturated polyester with low average degree of polymerization(UP)was synthesized by molecular design and then a block copolymerization modified unsaturated polyester resin with isocyanate was preparead by the copolymerization of UP and isocyanate(PU).The changes of molecular functional gro…
Woolen yarns are not advisable to be stored for a long time.It can result in waste to the textile manufacturers,if the piece end yarns are not used timely.The article inductive analyses the causes of piece end yarns,and proposes a solution which is from the viewpoint of design and production control.This paper introdu…
A PVC membrane selective electrode was prepared.The ion-associate of epinastine hydrochloride with sodium tetraphenylborate was used as the membrance carrier. The electrode shows a linear Nernst response in the range of 6.3×10-7～1.0×10-1 mol/L and the slope is 49 mV/pC,and the detection limit is 1.89×10-7 mol/L in hyd…
The correlation and regression relationship of electrostatic charging tendency(ECT) with 4parameters,i.e.,dissipation factor,volume resistivity,acid number and interfacial tension of transformer oil are investigated,which was aged with different oxygen injection content at 120℃.It is concluded that the oxygen speeds u…
The microstructure and properties of Cr12 steel after TD salt-bath vanadizing were investigated. The results show that after TD salt-bath vanadizing at 960 ℃ for 4.5 h,the Cr12 steel can obtain a surface coating with the thickness of 19.5 μm,and the coating with uniform thickess,compact and consecutive microstructure,…
The stretch fabric with the bicomponent filament(PTT/PET) is being developed.The gabric properties that include elongation,drapability,crease resistance and bending rigidity were measured in this paper.Comparing cotton elastic denim fabrics with spandex,the results showed that the bicomponent filament PTT/PET fabrics…
The thesis determined the contents and components of pigment in blood,silk gland and cocoon shell of natural colored cocoon and also studied the effect of cocoon drying on pigment in cocoon shell.The results showed that there were barely carotenoid in the green cocoon varieties and the components of flavonoids in bloo…
The functions of spraying rigid poly-urethane foam are observed in amount of catalyst,and amount of sort and amount of foam stabilizer.It had been found that,filling of prescription was better in producing poly-urethane foam when catalyst chose N,N-Dimethylcyclohexylamine and dibutyltin dilaurate(1:1,mass ratio) and t…
Air-atomized fog cooling is particularly suitable for the after-pot cooling of galvanized steel strips.With air and water serving as working media,an experimental study was conducted on the atomization characteristics of a newly-developed cross-flow type of fog nozzles.The water flux distribution,spray angle and press…
Copper phthalocyanine(CuPc) is a very important organic semiconductor material,and it has been widely used in organic field-effect transistors and organic solar cells because of its good optoelectric properties and excellent stability.In this paper,we briefly review features of CuPc in structure and properties,and the…
