Production process for disassembly forming of ceramic pedestal pan

Abstract

The invention discloses a production process for disassembly forming of a ceramic pedestal pan, which comprises the following process steps of: mould design; slip casting; die sinking and drying; billet adhesion; and glazing and sintering. The product qualification rate of the ceramic pedestal pan produced by the process can reach over 85 percent; and the pollution discharge and water conservation of the product meet and even exceed the standard of national water-saving products.

Description

Technical field [0001] The invention relates to the field of ceramics, in particular to a production process for disassembling and forming ceramic toilets. Background technique [0002] Ceramic toilets are generally composed of a water tank, a toilet body, and a seat that wraps the toilet body. The toilet body includes a bedpan and a pipe connected to the bedpan. The ceramic toilet can be divided into one-piece type and split type according to whether the water tank is connected with other parts. In the traditional production method, regardless of the one-piece or the split type, the molding production of the toilet is an integral one-time molding, that is, the toilet main body and the seat body are connected together, and the toilet is formed in a single mold. The production process is prone to the following problems: [0003] 1. The seat body and the toilet body are simultaneously formed at one time, and the adobe body is not balanced in drying and firing shrinkage (the seat bo...

AI Technical Summary

Problems solved by technology

[0003] 1. The seat body and the toilet body are molded at one time, and the adobe body is uneven in drying and firing shrinkage (the wall of the seat body is thick and flat, and the wall of the toilet body is thin and curved at the flushing pipe. The shrinkage rate and shrinkage direction are inconsistent), which may easily cause shrinkage cracking at each connection point between the seat body and the toilet body, or cause deformation of the pipeline due to the contraction of the seat body affecting the toilet body;

[0004] 2. The seat body and the toilet body are in the same mold, and the pipe is hidden inside the seat body. The mold design is difficult, and it is easy to cause product deformation and other quality problems when the mold is opened;

[0006] 4. In the overall one-time molding, the concentration of the mud is consistent, and it is difficult to adapt to the different requirements of the fluidity of the mud on the plane of the seat body and the bending of the pipe;

[0007] 5. In the overall one-time molding, due to the same molding and drying time, the moisture content of the seat body and the pipe is inconsistent, and the product molding and firing pass rate is difficult to stabilize and cannot be further improved
