【００３４】Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing an inorganic cement board used as a building material such as an exterior material. [0002] Conventionally, an inorganic powder material having a water content of 50% or less, which is mainly composed of cement, aggregate and fiber components, is sprayed on a belt and pressed between upper and lower dies. There is known a method for producing an inorganic cement board which is formed and then cured and cured. [0003] In this method of manufacturing an inorganic cement board, when the inorganic powder material is sprayed on the belt, it tends to cause unevenness in the spraying. In some cases, a portion of the body material layer in which the amount of the inorganic powder material was small occurred. In this case, there was a problem that the obtained inorganic cement board had a rough appearance. The present invention has been made in view of the above circumstances, and an inorganic powder material having a water content of 50% or less, which is mainly composed of cement and aggregate, is sprinkled on a belt, and the powder is dispersed vertically. An object of the present invention is to provide a method for producing an inorganic cement plate in which unevenness in the application of an inorganic powder material is prevented when employing a method for producing an inorganic cement plate which is cured by curing after press-forming between molds. [0005] According to a first aspect of the present invention, there is provided a method of manufacturing an inorganic cement board, comprising the steps of: providing an inorganic powder having a water content of 50% or less on a belt 6 with cement and aggregate as main components; In a method for manufacturing an inorganic cement board in which the material 1 is sprayed and press-molded between upper and lower molds and then cured and hardened, the inorganic powder material 1 vibrates in a horizontal direction on a track on which it falls on the belt 6. A dispersing device 2 having a net 20 is provided, and the inorganic powder material 1 is sprayed on the belt 6 through the net 20 of the dispersing device 2. In the method for manufacturing an inorganic cement board according to the first aspect , the dispersing device 2 includes a plurality of meshes 20 arranged in upper and lower stages, and the inorganic powder material 1 is passed through the meshes 20 arranged in the plurality of stages. It is characterized by being sprayed on. In the method for manufacturing an inorganic cement board according to the first aspect , the nets 20 are arranged vertically with their eyes shifted. In the method for manufacturing an inorganic cement board according to the first aspect, the mesh 20 is vibrated larger than an apparent opening from a vertical direction. The method for manufacturing an inorganic cement board according to the first aspect is characterized in that the net 20 is vibrated in parallel with the traveling direction of the belt 6. In the method for manufacturing an inorganic cement board according to claim 1 , an inorganic powder material 1 is formed on a green sheet 4 formed on a belt 6 by forming an aqueous slurry containing cement and aggregate as main components. Is sprayed. According to the method for manufacturing an inorganic cement board according to the first aspect, the inorganic powder material 1 is vibrated by spraying the inorganic powder material 1 on the belt 6 through the net 20 of the dispersing device 2. After being dispersed by the screen 20, it is placed on the belt 6. Therefore, the inorganic powder material 1 sprayed on the belt 6 is made uniform, and uneven spraying is improved. In the method for manufacturing an inorganic cement board according to the first aspect, the inorganic powder material 1 is sprayed on the belt 6 through a mesh 20 arranged in a plurality of stages, so that the inorganic powder material 1 Is dispersed each time it passes through the net 20 arranged in the belt 6, and the inorganic powder material 1 spread on the belt 6 is made more uniform. In the method for manufacturing an inorganic cement board according to the first aspect, since the nets 20 are vertically arranged so as to be shifted, the apparent openings in the vertical direction are reduced, and the inorganic powder material 1 is moved vertically. , It is easy to catch on the net 20 of each stage, and it is difficult to pass through the net 20. Accordingly, the degree of dispersion is increased, and the inorganic powder material 1 spread on the belt 6 is made more uniform. In the method for manufacturing an inorganic cement board according to the first aspect , the mesh 20 is vibrated larger than an apparent opening from the vertical direction to thereby obtain the inorganic powder material 1.
Are easily applied to the nets 20 of the respective stages arranged vertically, making it difficult to pass through the nets 20. Accordingly, the degree of dispersion is increased, and the inorganic powder material 1 spread on the belt 6 is made more uniform. [0015] In the manufacturing method for the inorganic cement board according to claim 1, wherein, by oscillated parallel to the traveling direction of the web 20 the belt 6, inorganic powder material 1 is removed from the necessary part on the belt 6 in the widthwise direction And it is difficult to scatter. Hereinafter, the present invention will be described in detail. First, the inorganic powder material 1 will be described. The inorganic powder material 1 contains cement as a binder, and various kinds of fiber components as an aggregate and other reinforcing materials as main components. Rate (the water content here is the weight percent of water when the weight of the solid content is 100%).
%, Which is a relatively dry powder prepared to less than 10%. As the cement, generally used cements such as Portland cement and blast furnace cement can be used.
The aggregate is not particularly limited and is selected from mineral aggregates and organic aggregates that are generally used depending on the intended use of the inorganic cement board.For example, silica stone powder,
Perlite, shirasu balloon, glass balloon, silica, gravel and the like are used. The fiber component is blended as a reinforcing component.For example, cellulose-based pulp fiber, mineral fiber such as asbestos, polypropylene, organic resin-based fiber such as vinylon, glass fiber, carbon fiber, metal fiber, and the like are used. Can be. In the present invention, the inorganic powder material 1 is placed on a track on which the inorganic powder material 1 falls on the belt 6.
After being dispersed by the dispersion device 2 having the net 20 vibrating in the horizontal direction, the dispersion is uniformly spread on the belt 6. Since the inorganic powder material 1 is clogged if the mesh 20 is too fine, the mesh 20 may have a size that allows the inorganic powder material 1 to be appropriately captured, dispersed, and passed. The shape of the mesh of the net 20 is generally a quadrangle, but is not particularly limited, and may be a triangle or a hexagon. It is desirable that the networks 20 are arranged in a plurality of stages vertically, and if there are no spatial restrictions, the networks 20
The greater the number of stages, the more uniformly the inorganic powder material 1 can be dispersed. At this time, the upper and lower nets 20
Is desirably in a state in which the eyes are displaced. In this case, since the apparent openings seen from the vertical direction are reduced, the inorganic powder material 1 is more likely to be caught on the upper or lower net 20. Further, it is desirable that the amplitude of the net 20 is larger than the apparent opening of the net 20 viewed from the vertical direction. This makes it difficult for the inorganic powder material 1 to pass through the mesh 20. In the case where the number of the nets 20 is one, or when there is no misalignment between the upper and lower sides of the net 20, the amplitude may be set to be larger than the aperture of the net 20. Further, it is desirable that the vibration direction of the net 20 be parallel to the traveling direction of the belt 6. That is, when the net 20 is vibrated so as to cross the traveling direction of the belt 6, the inorganic powder material 1 scatters at a portion that is not sandwiched between the upper and lower molds during press molding on the belt 6 or outside the belt 6. This is because there is fear. Reference Example Hereinafter, a reference example of the present invention will be described. FIG. 1 is a side view showing one manufacturing process of an inorganic cement board according to a reference example of the present invention. In the reference example, 40 parts by weight of Portland cement, 40 parts by weight of fly ash,

This inorganic powder material 1 is composed of 40 parts by weight of Portland cement,
It is prepared by adding 40 parts by weight of water to a solid material containing 5 parts by weight of vermiculite, 5 parts by weight of pulp, and mixing. In addition, the inorganic powder material 1 is sent out of the storage section 10 to the storage section 10 and the belt 6
An unloading device 7 for dropping on the upper surface of the upper green sheet 4 is provided. Above the belt 6, a dispersing device 2 for dispersing the inorganic powder material 1 is disposed on a track on which the inorganic powder material 1 sent out of the storage section 10 by the unloading device 7 falls. Is provided. The dispersing device 2 includes a net 20 that vibrates in parallel with the conveying direction of the belt 6.
The inorganic powder material 1 is dispersed by the net 20. As this net 20, as shown in FIG. 2, an upper net 20a and a lower net 20b are horizontally arranged at upper and lower openings of a frame 21 having a substantially rectangular parallelepiped skeleton. As shown in FIG. 3, each of the upper net 20a and the lower net 20b has a square eye with an opening of 20 mm, and is arranged in a staggered arrangement in which the eyes are shifted by half when viewed vertically from above. The apparent opening is 10 mm. The dispersing device 2 sets the network 20 to a frequency of 500 to 1
The material can be vibrated at 000 rpm. The inorganic powder material 1 is dispersed through the net 20 and dispersed on the green sheet 4. Thus, a multilayer plate 8 having a two-layer structure in which the green sheet 4 is used as the lower layer 5 and the inorganic powder material 1 placed on the green sheet 4 is used as the upper layer 3 is formed. Further, the multi-layer plate 8 is press-formed between upper and lower molds, and further cured and cured to obtain an inorganic cement plate in which the upper layer 3 has a concavo-convex pattern. In the reference example, in the above process, the inorganic powder material 1 is dispersed by vibrating the net 20 at a frequency of 700 rpm and an amplitude of 11 mm in the dispersing device 2 and dispersed on the green sheet 4 to obtain an external appearance.無機 無機 な 良好 良好 良好 良好. About this inorganic cement board,
Lower layer 5 caused by uneven dispersion of inorganic powder material 1
When the exposed portion (called a nest) was visually observed, the maximum length was 2.3 mm and the number of nests was 16. On the other hand, as a comparative example, in the above process, the inorganic powder material 1 is sprayed on the green sheet 4 without dispersing the inorganic powder material 1 by the dispersing device 2, so that the inorganic cement plate is formed. Obtained. When the nest of the inorganic cement plate was visually observed, the maximum length was 10 mm and the number of nests was 88. As described above, the dispersion target of the inorganic powder material 1 is
