Porcelain plate formed by one-time dry pressing of prefabricated mold and manufacturing method

Abstract

The invention discloses a porcelain plate formed by one-time dry pressing of a prefabricated mold and a manufacturing method. The porcelain plate comprises a flat blank layer and a prefabricated protrusion, the flat blank layer and the prefabricated protrusion are integrally formed by porcelain raw materials in a dry pressing mode, the height H1 of the prefabricated protrusion ranges from 8 mm to20 mm, and the thickness H2 of the flat blank layer ranges from 6 mm to 15 mm. According to the porcelain plate formed by one-time dry pressing of the prefabricated mold and the manufacturing method,safer curtain wall dry hanging application of the porcelain plate can be carried out through hanging pieces, the fact that the flat blank layer and the prefabricated protrusion are integrally formed in a dry pressing mode is adopted, the porcelain plate has the characteristic of being high in strength and good in integrality; and therefore, a curtain wall material with better physical and chemicalproperties and safer dry hanging is provided for dry hanging application of a building curtain wall.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to a porcelain plate formed by one-time dry pressing of a prefabricated mold and a manufacturing method thereof. Background technique [0002] With the development of construction technology and materials, architectural curtain walls have been more and more maturely applied to the interior and exterior walls of various buildings. [0003] In terms of curtain wall materials, there are various building plates such as aluminum plates, stone plates, ceramic plates, porcelain plates, and glass plates. In the selection of these building plates, with the further improvement of application needs and requirements, the market has a higher demand for curtain wall installation safety. , construction convenience, high efficiency, and the diversity of surface decoration effects of curtain wall materials have put forward higher requirements, and are developing towards prefabricated applicatio...

Problems solved by technology

[0011] Among the existing panels used in curtain wall technology, there is, for example, the technical scheme of "a kind of convex curtain wall panel" with the publication number CN110565853A, which describes a method of integral molding with clay as the main raw material by extrusion process. One-piece terracotta slabs with raised clamps and no need for secondary processing of plastic processes after conversion into rigid slabs, this method for extrusion processes is feasible for clay raw materials, but clay The performance of the product of the process has been described above in the present invention, and there are limitations, and the extrusion process does not have the industrialization of the current production and production of 800*800mm*10mm porcelain tiles, which only takes 40 minutes to complete the whole process of firing. The efficiency of continuous large-scale production, so the limitations of this process and products still need to be improved; and if the clay material is used for extrusion molding, the existing technology has not seen it, because its plasticity cannot meet the requirements of the clay material, and If the firing temperature does not reach 1150°C-1220°C, the formula raw materials cannot meet the powdery porcelain raw materials with a content of more than 16% alumina, more than 62% silicon dioxide, and more than 2% potassium sodium oxide after firing. Therefore, the technical solution of this kind of extrusion process for integrally forming porcelain raw material plates has limitations in the prior art, and there is no actual product that is actually realized.
