Abstract: The continuous development in the field of protective coatings and the search for newer rust-based anticorrosion with improved properties have led to the emergence of rust-based anticorrosion for high performance organic coatings for corrosion protection. In this study, one such rust-based anticorrosion coating have been formulated and coated over tinplate surfaces. The physical and anticorrosive properties of the coating were evaluated by accelerated laboratory tests (chemic immersion tests). The results are reported and conclusions are drawn in this paper.

Abstract: This paper briefly describes the situation of the development of China's iron and steel industry. Based on the introduction of the basis and the nature causes of hematite, the mainly used flotation process of hematite is discussed. The importance and urgency of improving technology, the research and development of new flotation reagent is put forward. The good development and utilization of hematite will have far-reaching economic and historical significance for the healthy and coordinated development of our national economy.

Abstract: It analyzed the reasons for the early cracks in high-performance concrete, and prepared overall program to improve the mechanical properties and the durability of the HPC. It studied on cracking control of HPC at early age and improvement of impermeability by mixing ratio test. The result showed that , it get better inhibition on the early cracks by reasonable adjustment to the water-binder ratio, fly ash and mineral fine powder dosage with saturated aggregates and the right amount of expansion agent, and it also provided high-performance concrete for different performance with a mixture ratio test methods.

Abstract: The electrochemistry property of the ferric-oxalate-gluconate complex was investigated using a gold electrode as working electrode. The peak currents of the ferric-oxalate-gluconate complex were found to increase linearly with square root of scanning rate displaying a quasi-reversible cyclic response of the redox process. The optimal conditions could be drawn from the cyclic voltammetry results and K/S values. That is 8.00 g/L ferric sulfate, 10.08 g/L oxalate, 17.92 g/L calcium gluconate and 45.00 g/L sodium hydroxide. Under this condition, we can not only get high reducing strength in the electroanalysis process, but also have cotton fabrics with good dyeability.

Abstract: A novel modified thermosetting phenolic resin was synthesized by bulk polymerization. The main process of the phenolic resin film formation was studied by tensile shear test. The preparation technology was determined by the investigation of viscosity behavior, gel properties and the data of DSC. The flexible rolled resin film was manufactured at 100±3°C while the moving speed of release paper is at 2 m/min on hot melt machine made in California Graphite Machines Inc. USA. The area weight of the film is 400±20 g/m2, the width of that is 300 mm and the thickness of that is 0.32±0.04 mm.

Abstract: The konjac glucom annan-Carrageenan edible blend films were prepared.The mechanical properties and the optical properties of the edible films were tested. The results showed that the properties of Blend Films is best when the mass ratio of blend films is 3:1, plasticizer glycerin can significantly improve the properties of blend films , this blend films is expected to develop into a new type of edible packaging films.

Abstract: The new adiabatic multiple coating is composed of surface coating and ground coating. The main raw material of surface coating is diatomite and that of ground coating is zircon powder. This paper separately study on the formula of the surface and ground coating. The results show that the adiabatic and other properties of composite coating are good and the coating can be used on the metal mold to cast the ferritic nodular cast iron (ferrite% ＞95%). And the using life of metal mold is improved.

Abstract: KH550 modified ZnO/TiO2 was prepared. The surface of nano-TiO2 was coated with ZnO derived from Na2Zn(OH)4 via a heterogeneous nucleation process, and coupling agent KH550 was used to treat the surface of ZnO/TiO2. Transmission electron microscopy (TEM), X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and Optical contact angle measuring instrument were used to characterize the effect of surface modification. The results showed that the surface of nano-TiO2 was coated by ZnO nanoparticles; After modified by the KH550, the modified ZnO/TiO2 showed better dispersion in water-toluene solution; and the surface of modified ZnO/TiO2 became more hydrophobic-lipophilic than that of modified uncoated nano-TiO2.

Abstract: Carbon nanotubes based on anodic aluminum nano-templates embedded with different metal catalysts were synthesized and the influence on the morphology of the products of the gas flow rate and the reaction time was closely investigated. The samples were characterized by field-emission scanning electron microscope. The results confirmed that the products are carbon nanotubes with controllable size and the morphology of the products were different with the different reation conditions.

Abstract: In Gleele-3500 Thermal Simulation Test Machine，conduct Thermal Simulation Experiment for High Niobium X80 Grade Pipeline Steel at Different Deformation Temperature, Deformation Extent and Coiling Temperature. Analysis the Microstructure Was Influenced by Different Rolling Process. According to the Thermal Simulation Experiments, Designed Test Scheme of Controlled Rolling and Controlled Cooling and Completed the Trial. the Results Showed that: for High Niobium X80 Grade Pipeline Steel, the Microstructures Are Acicular Ferrite and Have Good Mechanical Properties. the Low Temperature Impact Toughness Are More than 300J in -20°C and -40°C.
