Embodiment Construction

[0028] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0029] refer to figure 1 Shown, a kind of firing method of multilayer glaze ceramics, comprises the following steps:

[0030] 101. Preparing blanks: Accurately weigh the raw materials of the ceramic blanks according to parts by weight, pretreat the blanks, mix, pulverize, grind, and sieve to obtain the mixed blank raw materials;

[0031] 102. Glaze preparation: accurately weigh the raw materials for the glaze layer by weight, and mix, pulverize, grind, and sieve the raw materials for the mixed glaze layer after pretreatment with the glaze;

[0032] 103. Molding: making and molding the above-mentioned raw material of the embryo body, and drying it to obtain a green billet;

[0033] 104. Grinding blank rest: use tools to smooth the above green b...

Abstract

The invention relates to a firing method of a multi-layer glaze ceramic. The firing method comprises the following steps: blank preparation, glaze preparation, mold shaping, green milling and trimming, glazing, coloring, high-temperature firing and cooling formation, wherein blank preparation comprises: accurately weighing ceramic green raw materials in parts by weight, pretreating by virtue of a stirring technology or a milling technology, mixing, crushing, grinding and sieving. The firing method has the beneficial effects that with reasonable proportion of the ceramic green raw materials and a glaze layer raw material and pretreatment for many times, the firing finished product rate is increased, and the strength and the fracture toughness of the ceramic are also improved.

Description

technical field [0001] The invention relates to the technical field of ceramic products, in particular to a firing method for multilayer glazed ceramics. Background technique [0002] Traditional ceramic production generally adopts one-time firing process, which is characterized by simple process, less process, low cost, but low product yield, single tone, monotonous color, poor artistic effect, fragile, and poor fracture toughness. However, with the progress of society and the change of people's aesthetics, the requirements for the artistry, appreciation and practicality of ceramics are also getting higher and higher. Obviously, the traditional ceramic production process cannot meet the above needs. Therefore, ceramics painted with multi-layer glazes can be fired to produce ceramic products with rich colors, smooth colors, elegant and elegant, and gorgeous colors, but they still have not been able to improve the product yield. Low, poor fracture toughness and other issues....
