摘要： The invention provides that for each surface of a substrate (2) to be coated, a plasma is injected into a coating reactor (1) used for carrying out microwave PCVD methods, and the surface to be coated is perpendicularly orientated with regard to the direction of spreading of the corresponding plasma. Dielectric compensating elements (4a, b) are introduced into the vicinity of the microwave injection points (3) and correct for non-homogeneities resulting in the distribution of plasma thicknesses by altering the microwave field distribution.

摘要： Artificial zeolite is made using coal ash, particularly fly ash, as the starting material, and quality of the artificial zeolite that is produced depends on the composition of the starting coal. Since the production of zeolite is impaired unless the starting materials, including silicic acid and aluminum, that are used in the synthesis of zeolite for catalysts, which is called synthetic zeolite, are of high purity, starting material of low purity cannot be employed. Therefore, the topic was the development of a method of producing inexpensive artificial zeolite of the desired quality employing unused resources, such as descended pyroclastic materials, incineration ash, glass waste, diatomaceous earth waste, aluminum dross, etc., as the starting materials.
The present invention is a method whereby artificial zeolite is produced by heat treatment in the presence of water and alkali of an inorganic component comprising silicic acid or aluminum, or a mixture that has been obtained by adding glass, diatomaceous earth and aluminum dross, etc., to an inorganic component comprising silicic acid or aluminum. It is preferred that the alkali is sodium hydroxide or potassium hydroxide, the water and alkali are an aqueous alkali solution, the concentration of this aqueous alkali solution is 2 to 4 N, and heat treatment exceeds 100°C.

摘要翻译： 使用煤灰，特别是飞灰作为原料制造人造沸石，所生产的人造沸石的质量取决于起始煤的组成。 由于沸石的生产受到损害，除非用于合成沸石沸石的原料（包括硅酸和铝）被称为合成沸石，其纯度不高，所以不能使用低纯度的原料。 因此，本发明的主要目的是开发一种利用下游火山碎屑，焚化灰，玻璃废弃物，硅藻土废料，铝渣渣等未利用的资源制造所需质量的廉价人造沸石的方法。 本发明是通过在含有硅酸或铝的无机成分的水和碱存在下进行热处理或通过加入玻璃，硅藻土和铝渣等获得的混合物来制造人造沸石的方法。 涉及包含硅酸或铝的无机成分。 优选碱为氢氧化钠或氢氧化钾，水和碱为碱性水溶液，该碱水溶液的浓度为2〜4N，热处理超过100℃。
