摘要： PROBLEM TO BE SOLVED: To suppress generation of inferiority of appearance of a product, to lengthen a life of a felt and to improve productivity in a patterning process by a pressure dehydration press using the felt. SOLUTION: A method for pretreatment of a press felt 1 for a press process wherein a sheet body 4 from a hydraulic cement slurry is placed on a felt 1 and the surface is patterned by press dehydration by means of a press form 2 with joints 2A is provided. In this case, before the sheet body 4 is placed, the whole felt 1 is flattened by pressing it in advance by a larger pressure than a pressure applied on the joint part 1A of the press form of the felt.

摘要： An extrusion method and apparatus are described for producing ceramics, glass, glass-ceramics, or composites suitable for use as proppants. The method includes forming one or more green body materials, extruding the green body materials to form a green body extrudate, separating and shaping the green body extrudate into individual green bodies, and sintering the green bodies to form proppants. The apparatus includes a means for forming an intimate mixture of green body materials, means to produce a green body extrudate, means for separating and shaping the green body extrudate into individual green bodies, and means to sinter the green green bodies to form proppants.

摘要： Plastically formable material, which may be formed under pressure into desired shapes, is fed while in a fluid or plastically formable condition to a pair of cooperating surfaces which are relatively movable into compressive relationship with material disposed therebetween. The face of at least one of such surfaces is patterned with a plurality of juxtapositioned geometrical impressions of desired size and shape so as to form a ribbon or sheet of uniformly sized and shaped particles from the plastically formable material supplied to the cooperating surfaces. The uniform particles are initially joined together by thin web or edge portions which maintain the continuity of the newly formed particles within a sheet form. However, after the ribbon of newly formed particles has become sufficiently rigid, such as through the cooling of a molten thermoplastic material or the drying or firing of a green ceramic material from which such ribbon may be formed, the ribbon may then be flexed in various directions to separate the particles along the edge or web portions, thus providing a plurality of individual particles having substantially uniform size and shape.
摘要翻译：可以在压力下形成所需形状的塑性成形材料在流体或塑性可形成状态下被供给到一对可相对于其间设置的材料相对移动成压缩关系的配合表面。这些表面中的至少一个的表面被图案化为具有所需尺寸和形状的多个并置的几何印模，从而形成从供应到协作表面的可塑成形材料的均匀尺寸和成形颗粒的带状或片状。均匀的颗粒最初通过薄片或边缘部分连接在一起，这些纤维网或边缘部分将新形成的颗粒的连续性保持在片状。然而，在新形成的颗粒的带状物变得足够刚性之后，例如通过熔融的热塑性材料的冷却或干燥或焙烧可以形成这种带的生坯陶瓷材料，然后可以以各种方式弯曲带沿着边缘或腹板部分分离颗粒的方向，从而提供具有基本上均匀的尺寸和形状的多个单独的颗粒。
