摘要： An anti-propylene mask and method for preparation thereof is provided; the anti-propylene mask includes a fiber cloth contact layer, an antistatic non-woven fabric layer and a fullerene/nano titanium dioxide spunbond layer which are arranged in sequence; the fullerene/nano titanium dioxide spunbond layer is made by spun-bonding the modified resin material into a fiber web; the raw materials of modified resin materials include matrix resin, carboxylated fullerene derivatives, nano titanium dioxide, a lubricant, and a coupling agent; the modified resin material is prepared by following method: the carboxylated fullerene derivative is mixed and reacted with the nano titanium dioxide to prepare the carboxylated fullerene derivative-modified nano titanium dioxide, which is then blended and extruded with the remaining components in the raw material, and thus prepared. The mask can prevent propylene from entering the human body through the human respiratory organs and has a good anti-propylene effect.

摘要： The present invention relates to the production of filter membranes (10) and in particular to multilayered filters. The invention related to a method of producing a filter membrane (10) wherein at least two layers (12, 14) are sequentially built upon a forming member (18) such that, when the forming member (18) is removed, the resultant membrane (10) includes a plurality of apertures extending therethrough, and at least some of said apertures increase in cross-sectional area from a first surface of the membrane to a second surface of the membrane. The method of production reduces the risk of permanent plugging from particulates being trapped within the membrane itself and has strong bonds between the layers which reduce the risk of separation of the layers. The present method produces an even coverage of the forming member (18) which in turn results in a layer of uniform thickness. The layer can be controlled by changing the viscosity of the mixture into which the former (18) is dipped.

摘要： Methods are provided for making a porous filter that is useful in polymer melt spinning. The methods include pressing particles, such as a metal powder, to form a filter having a filter body integrally formed with a top cap and a bottom cap. The filter body and caps are formed as a single component or, alternatively, are formed as two or three separate parts that are fitted and pressed together to form a single component having blind inlet and outlet cavities. After pressing, the component is sintered to form the porous filter. The particles are pressed and cohere to form the caps and filter body without the use of a polymeric binder, and the inlet and outlet cavities are formed substantially without machining.

摘要： A method for forming dendritic metal powders, comprising the steps of: (1) heating a powder comprising non-dendritic particles, under conditions suitable for initial stage sintering, to form a lightly sintered material; and (2) breaking the lightly sintered material to form a powder comprising dendritic particles. In one embodiment, the lightly sintered material is broken by brushing the material through a screen. Another aspect of the present invention comprises the dendritic particles that are produced by the method described above. These particles can comprise any suitable metal, such as transition metals, rare earth metals, main group metals or metalloids or an alloy of two or more such metals. The particles can also comprise a ceramic material, such as a metal oxide. These particles are characterized by a dendritic, highly anisotropic, morphology arising from the fusion of substantially non-dendritic particles, and by a low apparent density relative to the substantially non-dendritic starting material. The present dendritic particles can be of high purity, and substantially free of carbon contamination.
