Abstract

The invention discloses a low-temperature energy-saving manufacture method for once-sintered printed glazed red soil pottery products. The manufacture method comprises the steps of manufacturing green bodies, painting, manufacturing glazing liquid, glazing and sintering and the like. The manufacture method changes the formula of the red soil green bodies, decreases the proportion of red soil in the green bodies, and increases the sintering degree of the green bodies; gas in the green bodies is released timely during sintering. Therefore, the phenomena such as glaze jumping, and foaming and husking are avoided. The pottery products can be formed through once sintering, so that the sintering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ceramic technology, in particular to a low-temperature, energy-saving, one-pass firing method for producing laterite painted and glazed pottery products. Background technique [0002] Authorized notification number CN101993237B is a method for manufacturing low-temperature laterite painted and glazed ecological pottery products invented by the applicant. This manufacturing method improves the traditional three-firing method for laterite pottery products. The red clay body is sent into the kiln for the first firing, and then painted and glazed after being taken out, and then sent into the kiln for the second firing to obtain the finished product. Compared with the traditional three-firing method, this method reduces the cost to a certain extent, but the energy consumption of the two-firing is still high. [0003] The reason why laterite pottery products are fired twice is because the laterite body of ...
