Problems solved by technology

[0003] At present, there are many kinds of display art porcelain on the market, and the production of many ultra-thin porcelain handicrafts is tedious, such as ultra-thin porcelain gauze towels. The production process generally includes dipping the selected gauze in ceramic slurry, and then shaping, drying, and finally put the dried gauze into a kiln for firing to obtain an ultra-thin porcelain gauze towel, but the existing ultra-thin porcelain gauze towel is not enough in thickness, strength, hardness, etc., and is easy to break further improvement

[0028] The preparation technology of Dehua ultra-thin porcelain scarf comprises the following steps:

[0029] Step 1: Apply the porcelain clay on the gauze and knead it repeatedly to make it a dense porcelain yarn;

[0030] Step 2, sending the porcelain yarn into the kiln for sintering, adopting an oxidizing atmosphere, and controlling the firing through four stages of variable temperature, the firing temperature is 1310±10°C;

[0031] Among them, the four-stage variable temperature control firing is as follows:

[0032] Low-temperature stage: from room temperature to 300°C in the kiln, and the kiln firing time is 0.8-1.2 hours.

[0033] Decomposition and oxidation stage: the temperature in the kiln is raised to 950°C, and the kiln is fired for 4-6 hours, and the gauze is completely burned out at 600-950°C;

[0034] High temperature stage: the temperature in the kiln is raised to 1310°C, and the kiln firing time is 2.5-3.5h;

Abstract

The preparation process of Dehua ultra-thin porcelain gauze includes the following steps: Step 1, apply porcelain clay to the gauze, and knead it repeatedly to make dense porcelain yarn; Step 2, send the porcelain yarn into the kiln Sintering is carried out in an oxidizing atmosphere, controlled by four stages of variable temperature firing, and the firing temperature is 1310±10°C. The porcelain clay includes the following raw materials: Dehua kaolin, Dehua Zimujie soil, Dehua low-temperature stone, inorganic pigments, porcelain The porcelain clay of scarves is made of Dehua kaolin, Dehua purple wood clay, Dehua low temperature stone and inorganic pigments. Dehua purple wood clay is rich in organic humic acid, which can greatly increase the plasticity and viscosity of porcelain clay. And make the dried thin green body strong and not deformed, so as to ensure the strength of the fired porcelain gauze towel.

Description

technical field [0001] The invention belongs to the field of porcelain gauze preparation, and in particular relates to a preparation process of Dehua ultra-thin porcelain gauze towel. Background technique [0002] Ceramics are various products made of clay and various natural minerals through pulverization, mixing, molding and calcination as the main raw materials. The articles made of clay and fired at high temperatures in special kilns are called ceramics. It is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes clay or a mixture containing clay. Products, from the roughest earthenware to the finest fine pottery and porcelain belong to its scope. [0003] At present, there are many kinds of display art porcelain on the market, and the production of many ultra-thin porcelain handicrafts is tedious, such as ultra-thin ...
