Technical Field
The invention relates to the field of ceramic cups, in particular to a manufacturing process of a ceramic cup.
Background
Ceramics are a generic term for ceramics and porcelain. The Chinese people invented the pottery as early as 8000-2000 before about the Gregorian. The ceramic materials are mostly oxides, nitrides, borides, carbides, and the like. Common ceramic materials are clay, alumina, kaolin, and the like. The ceramic material is prepared by extracting a large amount of clay resources on earth, has wide raw material sources, does not pollute the environment, does not destroy resources, and is non-toxic and harmless. Many manufacturers choose to burn ceramic materials into various ceramic cups, the ceramic cups are environment-friendly and durable, the ceramic cups are clean and tidy when being used, no peculiar smell exists in the ceramic cups, and the ceramic cups are very comfortable when being used.
Because the ceramic cup needs to be subjected to a series of complicated manufacturing process steps such as pugging, molding, demolding, blank making, blank drying, blank trimming, biscuit firing, glazing, glaze firing and the like, and the uncontrollable reason in the firing process, the ceramic cup has poor plasticity and is very brittle and can be broken after being slightly collided; in addition, the ceramic cup used for drinking tea often leaves tea dirt in the tea cup, particularly on the inner side wall of the tea cup after the tea is made for a long time, the attractiveness and experience feeling of the tea when the tea is drunk are influenced by the formation of the tea dirt, and meanwhile, the tea dirt enters the body along with tea water, so that harm is caused to the health of people.
Therefore, there is a need to develop a manufacturing process of a ceramic cup that is resistant to falling and collision and can effectively prevent tea stains from being generated inside the ceramic cup body.
