Opis:
Pure MCM-41 anchored benzene sulphonic acid (BSA/MCM-41), an efficient heterogeneous catalyst, was prepared for the synthesis of CL-20 from TAIW. The prepared catalysts were fully characterized by FTIR, XRD, TEM, TG, N2 adsorption techniques, elemental analysis and acidity tests. It was observed that the catalyst (BSA/MCM-41) retained the mesoporous structure like MCM-41, exhibited excellent thermal stability and high activity. Compared with a blank, the high catalytic activity promoted shorter reaction times by a factor of 3/5. In addition, this catalyst could be reused at least five times without significant loss of its catalytic potential. Moreover, the BSA/MCM-41 catalyst exhibited an optimal catalytic performance, with a high to excellent yield of CL-20 (92.5%) with a purity of 98.3%, under the optimum synthesis conditions.

Opis:
The paper described the experimental findings of underwater wet welding of E40 steel using self-shielded flux-cored wire with a TiO2 -FeO-MnO slag system. The arc stability, weld quality and corrosion resistance with different heat inputs were studied. The results showed that the wet welding process of the designed wire displayed good operability in the range of investigated parameters. The microstructure and mechanical properties of the weld metal depended on the heat input. Due to the high fraction of acicular ferrite in the weld metal, the mechanical properties of the weld metal under low heat input had better tensile strength and impact toughness. Fracture morphologies at low heat input had uniform and small dimples, which exhibited a ductile characteristic. The diffusible hydrogen content in the deposited metal obtained at a heat input of 26 kJ/cm significantly reduced to 14.6 ml/100g due to the combined effects of Fe2 O3 addition and the slow solidification rate of molten metal. The microstructure also had a significant effect on the corrosion resistance of the weld metal. The weld metal with high proportions of acicular ferrite at low heat input exhibited the lowest corrosion rate, while the base metal possessed a reduced corrosion resistance. These results were helpful to promote the application of low alloy high strength steel in the marine fields.
