Embodiment Construction

[0018] A new type of glazed surface and its manufacturing process, including formula preparation-ball milling and sieving-firing, wherein the ball milling and sieving is obtained by putting the above-mentioned raw materials into a ball mill until they pass through a 325-mesh sieve:

[0019] 1) Modulation formula

[0020] Described raw material composition weight percent is:

[0021] SiO 2 50—70%, Al 2 o 3 5-15%,

[0022] K 2 O+ Na 2 O 0-2%, CaO 5-15%,

[0023] MgO 0—5%, ZnO 2—5%,

[0024] BaO 0—3%, ZrO 2 5-15%;

[0025] 2) Ball milling and sieving

[0026] The raw material is a powder of 200 mesh or more, and the raw material is put into a ball mill for ball milling. During processing, the quartz is pre-ground for 8-10 hours, and then other raw materials are added for ball milling for 3-5 hours.

[0027] 3) firing

[0028] Fire at a temperature of 1230°C-1250°C, and keep the temperature at the highest temperature for more than 2 hours.

[0029] The raw materia...

Abstract

The invention discloses novel glaze and a manufacture process thereof, wherein the glaze is high in compactness and abrasion resistance, good in smoothness and small in pore. The manufacture process includes steps of selecting of raw materials, matching, hard fire and the like, the manufactured glaze is good in high-temperature flowing property, and further the raw materials are large in surface tension, so that in high-temperature melting of the glaze, the surface tension of the glaze is higher than that of traditional glaze materials, and smooth effect of the glaze is achieved through interaction of the high-temperature flowing property and the surface tension. In addition, gas in the glaze can be discharged easily without leaving marks, and no small pores can be left, the glaze is easy to clean. Solvents used in the formula are mostly alkaline-earth metals, so that use amount of alkaline metals of potassium oxide and sodium oxide is reduced, rigidity of the glaze is improved, and abrasive resistance of the glaze is improved.

Description

technical field [0001] The invention relates to a glazed surface, in particular to a glazed surface with high density, high wear resistance, good smoothness and few pores and a manufacturing process of the glazed surface. Background technique [0002] The glazed surface refers to the glass dense layer that is fused and covered on the surface of the green body. It can improve the surface properties of ceramic products, make the surface of the product smooth, impermeable to liquid and gas, and not easy to be stained. In addition, it can also improve the mechanical properties of the product. Strength, electrical properties, chemical stability and thermal stability. The glaze also plays a decorative role on the body. It can cover the bad color and rough surface of the body. The surface tension of the glaze has a great influence on the appearance quality of the glaze. If the surface tension is too small, it will easily cause glaze flow and form when the small pores on the glaze s...
