[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;
[0035] Heat preservation stage: the temperature...
