    • This invention relates to a composite tubular article used as a belt which is suitable for fixation on an image forming apparatus such as a duplicating machine, particularly for heat fixation, and to its production method. Conventionally, a belt having a polyimide resin on the inner layer and a fluororesin on the outer layer is known as an image fixing belt but this belt involves the problems that a clear and vivid image cannot be obtained because the thickness of each layer is not uniform and a lusterless or so-called "mat" image cannot be obtained due to a smooth belt surface. To solve the problems with the prior art technique described above, the present invention provides a composite tubular article consisting of a tubular inner layer made of a polyimide resin and a tubular outer layer made of a fluororesin, whereby surface coarseness of the outer peripheral surface of the fluororesin tubular outer layer is from 1 to 10 mu m. As the production method of this article, the present invention provides a method which comprises forming the outer layer by use of a cylinder having an inner peripheral surface having surface coarseness of 1 to 10 mu m and forming the polyimide resin tubular inner layer on its inner peripheral surface by imidation of a polyamidic acid, or a method which comprises dipping the inner layer formed by the imidation of the polyamidic acid in a fluororesin solution in which particles having a particle diameter of up to 5 mu m are dispersed or spraying the solution to the inner layer to form the outer layer.
    • 本发明涉及一种用作带子的复合管状制品,其适用于固定在诸如复印机的图像形成装置上,特别是用于热定影,以及其制造方法。 传统上,在内层具有聚酰亚胺树脂的带和外层上的氟树脂已知为图像定影带,但是该带涉及由于每层的厚度不均匀而不能获得清晰和生动的图像的问题 并且由于光滑的带表面而无法获得无光泽或所谓的“垫”图像。 为了解决上述现有技术的问题,本发明提供一种由聚酰亚胺树脂制成的管状内层和由氟树脂制成的管状外层构成的复合管状制品,由此外表面的表面粗糙度 氟树脂管状外层为1〜10μm。 作为本发明的制造方法,本发明提供一种方法,其包括使用具有表面粗糙度为1〜10μm的内周面的圆筒形成外层,并在其内部形成聚酰亚胺树脂管状内层 通过酰胺化聚酰胺酸的外周表面,或包括将通过聚酰胺酸的酰亚胺形成的内层浸渍在其中分散有粒径至多5μm的粒子的氟树脂溶液中或将溶液喷雾到 内层形成外层。

    • PURPOSE: A manufacturing method of a silicone-coated roller without a build line is provided to prevent the formation of a building line by minimizing an edge line of a strip due to the orientation of pigment/filler-containing particles. CONSTITUTION: A manufacturing method of a silicone-coated roller without a build line is as follows. The extruded, pigment/filler-containing addition-curable silicone rubber strip(2) wrapped around a base material(1) in a state where the edges of adjacent strips are welded. The hardened silicon rubber hardens in order to a vulcanized silicon rubber layer unified in the material. The surface of exposed silicon of a polymer faced roller is machine-processed. Pigment and filler have a size and shape that makes cured silicone elastic member not form the build line.
    • 目的:提供没有生产线的硅树脂涂布辊的制造方法,以通过使由于颜料/含填料的颗粒的取向引起的条带的边缘线最小化来防止建筑物线的形成。 构成:没有生产线的硅氧烷涂布辊的制造方法如下。 在相邻条带的边缘被焊接的状态下缠绕在基材(1)周围的挤出的含颜料/填料的可加成固化的硅橡胶条(2)。 硬化的硅橡胶硬化,以使硫化硅橡胶层在材料中一体化。 对聚合物面辊的暴露硅表面进行机械加工。 颜料和填料具有使固化的硅氧烷弹性构件不形成生产线的尺寸和形状。
