Embodiment 1

[0013] A medium-temperature high-alumina strengthened porcelain, the body of which includes the following components (by weight): 15% of Datong soil, 10% of weathered potassium feldspar, 11% of alumina, 24% of Hunan washing mud, and 2% of Jiangxi lithium porcelain stone powder , Hunan black feldspar 10%, calcined talc 3%, Jiepai soil 14%, quartz 8% and Guizhou soil 3%.

[0014] After batching according to the above ratio, put it into a ball mill and add water to ball mill, sieve to remove iron, press filter, rough smelt, stale, scouring, molding, drying, glazing, firing, inspection, packaging.

[0015] Said billet is added water ball mill according to material: ball: water=1.0:1.9:1.0 weight ratio adds water, ball milling time is 20 hours, ball milling fineness is less than 0.1% by sieve remaining 250 orders, and sieve remaining 325 orders is less than 0.3%; The sieve is 200 mesh; the Gauss intensity of the iron removal is 10000 Gauss intensity, and it is continuously sieved f...

Embodiment 2

[0018] A medium-temperature high-alumina strengthened porcelain, the green body of which is the following components (by weight): 20% of Datong soil, 5% of weathered potassium feldspar, 15% of alumina, 15% of Hunan washing mud, and 2% of Jiangxi lithium porcelain stone powder , Hunan black feldspar 9%, calcined talc 5%, Jiepai soil 20%, quartz 5% and Guizhou soil 4%.

[0019] After batching according to the above ratio, put it into a ball mill and add water to ball mill, sieve to remove iron, press filter, rough smelt, stale, scouring, molding, drying, glazing, firing, inspection, packaging.

Abstract

The invention discloses a middle temperature high-alumina intensification ceramic and manufacturing technique, which comprises the following parts: big-same-sand, wind-transmission potash feldspar, alumina, hunan-wash-mud, Jiangxi lithium chinastone powder, Hunan blach feldspar, calcinations talcum, boundary board soil, and quartz and Guizhou soil. The manufacturing technique comprises the following steps: batching; adding in water and abrading-ball; riddling and deironing; filter-pressing; pugging; ageing scouring; forming; drying; glazing; firing by kiln oven. The veintion has high transverse strength and good heat endurance.

Description

technical field [0001] The invention relates to a strengthened porcelain and a production process thereof, in particular to a medium-temperature high-alumina strengthened porcelain and a production process thereof. Background technique [0002] At present, the production of high-alumina reinforced porcelain in the market has the disadvantages of high raw material cost, high firing temperature (1350-1400°C), and high energy consumption. Chinese Patent Publication No. CN1548399A, published on November 24, 2004, the name of the invention is a reinforced porcelain and its production process. The application discloses a low-temperature fast-fired magnesia reinforced porcelain and its production process. Chinese Patent Publication No. CN1548400A, published on November 24, 2004, the name of the invention is a kind of strengthened porcelain and its production process. The application discloses a high-silicon reinforced porcelain and its production process. In the production process...
