The synthesized novel 8-anilino-1-naphthalenesulfonic titanium complex was used as catalyst for ethylene and norbornene copolymerization.The polymerization behavior of synthesized titanium complex was typically studied by varying various parameters,types of cocatalyst,concentration of norbornene,Al/Ti molar ratio,poly…
For cold rolling process,deformation level is an important factor to influence the deformation resistance.A mechanism model of deformation resistance combined with actual rolling data is established.Taking low carbon steel 08AIA as an example,using a large number of actual rolling data in stable operation and the leas…
EDTA chemical cleaning technology for new founded boiler and how to recycle the EDTA were reviewed.And the methods were applied to the new boiler of Erdos Co.,Ltd.PVC units,which was proved better cleaning technology and achieved better economic benefits.
The band structure,total density of states and partial density of states of pure and V-doped wurtzite ZnO have been investigated by using the first-principle ultrasoft pseudo potential approach of the plane wave.The calculation indicates that the lattice of ZnO has a little inflation,and that the band gap is reduced b…
The electrochemical parameters of seven ZA27 alloys,which contains(mass fraction) 3.0%Cu,0.06%Mg,0.1%Si,0.75%Mn,0.2%Sb,0.1%Sn and no alloy element,respectively,such as self-corrosion potential,linear polarization resistance,self-corrosion current and Tafel constant,were measured by using PS-168C electrochemistry measu…
In this paper,using the emulsion grafting copolymerization of styrene and acrylonitrile onto the PB and SBR latex in which the mass fraction of PB was 60%,ABS resins were prepared by blending ABS graft copolymer with SAN resins.The relation between the impact strengh and the morphology of ABS resins was studied.The re…
The combination of deformation process parameters matched with good tensile property was achieved after TA7 titanium alloy imitating-level orthogoml experiment and variance analysis of tensile property test result at room temperature.The combination of deformation process parameters is billet heating temperature 1040℃…
The ground radial tire rubber was reclaimed by self-prepared reclaiming agent,and the effects of the particle size of ground radial tire rubber,additon level of reclaiming agent and softener on the physical properties of reclaimed rubber were investigated.The results showed that,with increase of the particle size of g…
Sb doped barium titanate were prepared by solid reaction method,using BaCO3,TiO2 and Sb2O3 as raw materials.The crystal structure,lattice constants,electromagnetic properties and microwave absorption characteristics of the prepared samples were characterized by XRD,Raman spectroscopy and vector network analyzer,respec…
Calcium phosphate cement(CPC) has wide application prospect in the orthopedic field due to its favorable biocompatibility and conductivity.But its poor mechanical property has limited its range of clinical application.Therefore,it needs researches to improve its strength.From the aspects of preparation conditions,comp…
The influence of 3A molecular sieve on the performance of silicone rubber foam is studied in this paper.The results were shown that tensile strength,compression permanent deformation,density,hardness,moisture absorption rate was increased with the 3A molecular sieve content,the breaking elongation was decreased,and fo…
Current situation of study on the mechanism of martensitic transformation was reviewed generally and superficially.It was pointed out that shear mechanism is immature,and is a misunderstanding.In order to initiate a new aspect in the study on martensitic transformation,renewal of study on the mechanism of martensitic…
Ceramic coatings were prepared on suface of MB8 magnesium alloy by micro-arc oxidation(MAO) technology in an environmental-friendly solution.The current density-time responses were recorded during different MAO processes.The surficial morphology,thinkness and composition of the coatings were studied by scanning electr…
The precursors were prepared via a co-precipitation method using Na2MoO4 solution as the precipitator.Powders were obtained by calcining the precursors at 850~950 ℃ in air atmosphere.X-ray diffraction(XRD),scanning electron microscope(SEM) and fluorescence spectrum were used to characterize the structure and luminesce…
Effect of heat treatment on properties of Al-7.0Zn-1.4Mg-1.5Cu-0.14Zr aluminum alloy extruded products containing strontium was studied by means of microhardness tester and electronic conductivity test,tensile test,intergranular corrosion and exfoliation corrosion experiments,and optical microscopy(OM) and scanning el…
The chemical composition,microstructure and micro-hardness of carburized layer on the gear tooth of a veering fan-shaped rocker shaft were examined respectively.The macroscopic and microscopic appearances of the fracture were observed.The results show that the main reason for the tooth fracture is the machining defect…
In order to investigate the limited lean in surfacing deposition forming process as well as the influence of wire feeding speed and surfacing speed on the limited lean,a single bead and multi-layer forming test was carried out with MIG surfacing deposition technology.The relationship between the limited lean and techn…
Aqueous monoethanolamine(MEA) is the mostly used absorbent for removing carbon dioxide(CO2) from fuel gas in the industry.Improving the performances of aqueous MEA is the key for the effective CO2 removal.The absorption,regeneration performances and corrosion properties of MEA and its four blends with polyamines(MEA/p…
