Description
Technical Field
The utility model relates to a building pottery field, concretely relates to prefabricated mould dry pressing fashioned porcelain board goods.
Background
With the development of construction technology and materials, building curtain walls have been more and more mature to be applied to the inner and outer walls of various buildings.
In the aspect of curtain wall materials, various building boards such as aluminum plates, stone plates, ceramic plates, porcelain plates, glass plates and the like are used, and in the selection of the building boards, along with the further improvement of the requirements, the market puts higher requirements on the installation safety of the curtain wall and the diversity of the surface decoration effect of the curtain wall materials; in addition, with the improvement of safety awareness of decoration application, the plate sticking in some specific occasions also requires relatively higher firm force.
In order to achieve the comprehensive effect of the texture of the physical and chemical properties of the material, the design of the safety guarantee of the application of the material structure and the diversity of the surface decorative effect of the material, higher requirements are put forward for the board and the production.
The curtain wall method in the prior art mainly adopts a dry hanging mode, the plate is fixed on the wall surface through a hanging piece, and the methods generally adopt various groove type methods, punching back bolt type methods and the like, and the methods all need to cut and grind the plate per se to cause certain damage, so that the requirements on the strength, hardness and density performance of the plate per se are high, and the requirements need to meet the standard requirements of relevant specifications.
When the existing method for slotting or punching the plate is used for construction, on one hand, the plate needs to be thick, high in density and high in strength and hardness so as to reduce the influence on safety caused by damage to the plate body due to slotting or punching, and on the other hand, the plate needs to be lighter in weight so as to reduce the load of the curtain wall.
In the curtain wall in the prior art, except for the glass curtain wall, for example, in the curtain wall plates of ceramic plates, aluminum plates, stone materials, artificial stones and the like, ceramic plates mainly made of pottery clay are formed by extrusion process and roasting, the highest temperature is generally 900 plus 1100 ℃, the production efficiency of the process is very low, and the industrial continuous large production ratio of each production line of the building ceramic which can reach ten thousand square meters or even tens of thousands square meters per day can not be achieved, and the process has no advantages of industrial production; the water absorption rate of the ceramic brick reaches more than 10 percent, the change of expansion with heat and contraction with cold under the conditions of climate change in south and north regions, seasonal climate change and the like is large, particularly the characteristic of high water absorption rate is high, water is easy to absorb in wet weather such as rain and the like, so that the load of the ceramic plate is increased, even the performance is influenced, and the load bearing of the wall structure is increased; and for the plate of the pottery clay process, the color is single, the surface of the plate has almost no decorative effect except the body color, and the plate has no abundant and various surface effects which are like the ink jet machine of a ceramic tile production line and the matched process treatment and can almost restore various vivid random color patterns such as various stone grains, wood grains, cloth grains and the like, so the plate formed by the extrusion process, especially the pottery clay plate, has certain limitations on the application performance and the decorative effect and needs to be improved.
For example, although the aluminum plate curtain wall is light, the color is monotonous, and the decoration richness is lacking, which needs to be improved.
For example, the stone curtain wall is formed by natural resources, the color difference is difficult to unify, the texture is different, the pores are more, waterproof protection is required, a certain thickness is required to support the using strength of the stone curtain wall, but the increase of the thickness also brings the increase of load, so the physical and chemical properties of the stone curtain wall are limited to a certain extent, and the stone curtain wall is more sensitive to the influence on the strength when being used as a groove, a hole and the like during dry hanging.
The ceramic plate in the prior art is formed by pressing through a large-tonnage press and is formed by firing at a high temperature of more than 1150 ℃, so that the ceramic plate is better than a ceramic plate and a stone in the physical and chemical properties of strength, hardness, acid and alkali resistance, rapid cooling and heating resistance and the like. Therefore, the ceramic plate is used as a curtain wall for dry hanging, which is a trend in the industry. In addition, in the prior art, all ceramic plates which can be applied to the curtain wall are conventional integral flat plates, and because the ceramic plate blank is pressed by large tonnage and sintered at high temperature, the density is high, the quality of the plane plate with unit thickness and area is heavier, the load on dry hanging is larger, and if the ceramic plate blank is too thin, the thickness of the corresponding position is reduced to be thinner than that of other flat plate blanks due to grinding and cutting of grooving and punching when the ceramic plate blank is used for dry hanging, so that potential safety hazards caused by the reduction of the strength of the grooving and punching positions are generated. Therefore, in order to reduce the load, have higher strength required by reaching the standard, and have a low water absorption ceramic plate less than 3%, even less than 0.5%, which is used for curtain wall dry hanging, the direction of research and attack of the industry personnel is changed.
However, in the existing plates for curtain wall technology, there is a technical scheme of "a sunken curtain wall plate" with publication number CN110565853A, which describes a method of integrally forming by using pottery clay as a main raw material through an extrusion process, and an integrated pottery plate containing a raised clamping block is manufactured without performing secondary processing of a plastic process after the pottery plate is converted into a hard plate, and the method for the extrusion process is feasible for using pottery clay as a raw material, but the performance of the products of the pottery clay process is described in the above of the utility model, which has limitations and does not have the efficiency of industrial continuous mass production, so the limitations of the process and the products still need to be promoted; however, if the porcelain clay raw material is used for extrusion process forming, the prior art does not know, and the scheme of integrally forming the porcelain plate by the extrusion process is limited and infeasible in the prior art because the plasticity of the porcelain clay raw material cannot meet the requirement of the porcelain clay raw material, and the formula raw material cannot be completely sintered if the firing temperature is not 1150-1220 ℃.
However, there are also two technical solutions in the prior art, such as the solution disclosed in publication No. CN101250930A (divisional application No. 200510053355.8), which describe that a polishing and grinding mold with a predetermined design shape is used to manufacture a ribbed plate, and the design is totally different from the design of a plate which is formed by dry pressing and molding ceramic powder into a plate with raised ribs having a height not less than 8mm and a plate blank thickness not less than 8 mm.
Therefore, it is necessary to provide a solution suitable for dry hanging curtain walls or ceramic panels with increased paving and fastening strength.
