2.Industrial high performance foams, fine celled polyurethane foams, cellular silicone foams, liquid silicone rubber, high frequency circuit materials, flexible circuit materials.
3.The Development of Microfoam with Super-Low Density for ICF Target Fabrication
5.Abstract: Metallic foam or porous materials were developed at the end of the 80"s and applied to industry at the beginning of the 90"s.They have excellent physical properties,especially damping characteristis,so they are widely used for vibration insulation,noise elimination,electromagnetic screening and so forth.A description is given of the “casting and foaming” method for the fabrication of these metallic foams,and a detailed account of their mechanical and damping properties.
6.The mechanical properties of HDPE structural foams modified with short Nylon-6 fiber and filled with wood powder were reported, the adhesive effect of the adhesive between short Nylon-6 fiber and HDPE foam was discussed, and the influence of different processing additire on processing property and appearance of HDPE foam filled with wood powder was analysed.
8.Cut out several seaweed pieces from green craft foam. Poke a hole nea the bottom of each. Use fishing line to tie a metal nut to each piece of seaweed.
9.The results show that the fluidity of magnesium can be greatly improved in vacuum low-pressure EPC,moreover,it is increased with increasing gas flux and decreasing coating thickness. The optimized parameters is as follows:gas flux of 3~5 m3/h,pouring temperature at 750~780 ℃,coating thickness of 0.3~0.5 mm,pattern materials density of 0.16 mg/cm3,vacuum rate less than 0.03 MPa.
10.Two improved design blueprints are advanced: magnetic field seal butterfly valve and foam plastic butterfly valve, which obtain the ratification of the factory of ShiJiaZhuang valve.
