Production method of once sintered double piece large specification stairstep brick

Abstract

This invention discloses a production method of a kind of a two-unit firing large terraced brick, its characteristic lies in its preparation steps: (1) brick ingredients formed; according to the formula-based materials and ingredients for pigment grinding powder, mixture, add dies after suppressing press molding; (2) dry and adobe processing, guarantee drying water below 0.5%, appropriate fillet processing, cut 2~3mm from straight border; (3) glazing and stamp, use peak facilities glaze counter-glazing, with minimum volume; (4) sintered, using a kiln, high-temperature slow burning, 90 minutes cycle; (5) cutting; cut brick into two from middle and then chamfering, and other sophisticated processing; (6) the packaging. The stairway brick production by the method of the invention has great specifications, thin in thickness, low cost, good decorative effect and so on.

Description

technical field [0001] The invention relates to a method for preparing ceramic tiles, in particular to a method for producing large-scale stepped bricks. Background technique [0002] At present, the stepped bricks on the market are basically 300×300mm and 300×600mm single-piece wear-resistant bricks. The reason is that large-scale stepped bricks cannot be turned around on the assembly line, and are easy to slip, and there are problems such as low yield and high cost in manufacturing that need to be solved. In addition, the existing single-piece wear-resistant stepped brick also has disadvantages such as insufficient color and poor sense of hierarchy because the brick surface is not printed. For example, the application number is 97106364, the application date is April 8, 1997, and the invention name is a patent application for the production process of stepped bricks, which includes mold pressing into blanks, drying, bisque firing, glazing, and glaze firing. It is characte...

AI Technical Summary

Problems solved by technology

This patent adopts a relatively large-sized green body that is fired and then cut in half, but the specifications and surface decoration effects still cannot meet the needs of high-end places such as halls, villas, etc.

There are also large-scale stepped bricks, but they are basically polished bricks and stones processed by arc polishing, grinding, cutting, etc. It has high-grade texture, but there are complex processes, high production energy consumption, high cost, and low product yield. Poor anti-fouling and anti-skid effects, large color difference, etc., and due to its ingredients and process constraints, it is impossible to prepare larger-sized cascade bricks
