摘要:
A method for manufacturing molded foam which uses cheap materials, is light in weight and which is excellent in impact resistance. In the method for manufacturing molded foam, propylene homopolymer with a long chain branch, propylene ethylene block copolymer and low density polyethylene are mixed in the base resin at a prescribed mixing ratio. A blowing agent is added to carry outfoaming. A prescribed mixing ratio is determined based on the value arrived at by a multiplying melt tension of each material mixed with the melt flow rate and the Tensile Rupture Elongation.

An object of the invention is to provide a blow-molded foam which has homogeneous foamed cells in size, is light in weight, and is excellent in surface smoothness, and a process for producing the same. The invention is directed to a blow-molded foam 1 having a wall portion formed in such a manner that a thermoplastic resin containing a foaming agent mixed therewith is subjected to blow molding. Herein, the wall portion has a closed cell structure in which a plurality of foamed cells are contained. The wall portion has an expansion ratio of not less than 2.0 times. The wall portion has an outer face having a center-line average surface roughness Ra of less than 9.0 μm. The foamed cell has a cell diameter having a standard deviation of less than 40 μm in a thickness direction of the wall portion.

A method for manufacturing multilayer foam where easy generation of dead air and improvement in foam magnification is offered. Multilayer resin that has non-foam layer outside foam layer is pushed out, the innermost side of the multilayer resin is bonded mutually, and multilayer resin laminating body is formed. Multilayer resin laminating body is clamped in the empty space between outermost side of multilayer resin laminating body and cavity side with metal mold. Multilayer resin laminating body is molded in the shape along cavity side, and the multilayer foam is molded.

The invention provides a molded foam molding method capable of obtaining a molded foam in which pinholes may not be formed with ease even when a blow ratio is high and which has a high expansion ratio. The invention also provides a molded foam which includes no pinholes, is reduced in weight, and is excellent in heat insulating property. The molding method includes blending a polypropylene-based resin having an equilibrium compliance from 2.0 to 6.0 (10−3×Pa−1) with a foaming agent and kneading the blend in an extruder. The extruded foamed resin is molded so as to be fit along a mold by a pressurized fluid. Moreover, the molded foam is formed by the method described above, and has an expansion ratio from 1.5 to 5.0 times and an impact strength of not less than 30 kg·cm.

A radiological image processing apparatus of this invention includes a separating device, an adjusting device and a removing device. Since a corrected image is generated using the radiological image taken through an object under examination, each image can be acquired by one radiographic operation without acquiring data for grid correction beforehand. The radiological image taken through the object is separated into a grid image and a non-grid image, and a corrected image is generated by adjusting intensity of the grid image on real space based on the non-grid image. Thus a high-precision correcting process is realized by one radiographic operation.
