Embodiment Construction

[0023] The present invention will be further described below in combination with embodiments.

[0024] A preparation method of high thermal stability, high strength jade glazed daily-use porcelain, comprising the following raw materials:

[0025] The recipe ingredients are: Sio 2 Mineral, AL 2 0 3 Mineral, K 2 0 Mineral, B 2 0 3 Minerals, ZnO minerals, boron zinc frit, zirconium white frit, solvent;

[0026] The steps are as follows:

[0027] a. Ingredients ball milling and mixing: the user puts each solid raw material into a ball mill for high-speed ball milling in advance, and then ball mills each raw material into a powder state, and then uses a screen to screen the ball-milled powder, and the user ball-mills the finished powder Put each raw material powder into the reaction kettle, then add an equal portion of deionized water into the reaction kettle, and then use an electric mixer to divide the raw materials into three modes: fast, medium and slow, and mix them unt...

Abstract

The invention provides a preparation method of jade glaze daily porcelain with high thermal stability and high strength. Raw materials of the formula comprise a SiO2 mineral, an AL203 mineral, a K20 mineral, a B203 mineral, a ZnO mineral, a boron-zinc frit, a zirconium white frit and a solvent. The preparation method comprises the following steps of: a, burdening, ball-milling and mixing; b, refining and ageing; c, blank forming; d, drying and cooling; e, glazing and glaze firing; and f, finished product detecting and discharging. Through cooperation of the above procedures, the proportion ofporcelain raw materials can be changed by adding the boron-zinc frit and the zirconium white frit; the reaction among the porcelain raw materials is better; moreover, crystal phase development compactness is promoted, refractory substances such as free quartz are reduced, the density of the porcelain body is improved, cracking of a porcelain finished product in the firing process is prevented, thestrength of the porcelain finished product is improved, meanwhile, the glaze surface on the surface of the porcelain shows jade appearance, and the overall appearance of the porcelain is also improved while daily use is met.

Description

technical field [0001] The invention relates to the field of porcelain, in particular to a preparation method of high thermal stability and high strength jade-glazed daily-use porcelain. Background technique [0002] Porcelain is made of porcelain stone, kaolin, quartz stone, mullite, etc., with glass glaze or painted objects on the outside. Various chemical changes occur due to the difference in temperature. [0003] According to the existing porcelain firing methods, the high thermal stability of the produced porcelain products is poor, and cracks are prone to occur during the firing process, which cannot promote the development and compactness of the crystal phase, increase free quartz and other refractory substances, and reduce the porcelain body. Density and low strength. At the same time, the glaze on the surface of the porcelain does not have a jade-like appearance, which cannot meet the needs of daily porcelain use. Most of them can only be used as ornamental porc...
