Abstract

The invention discloses a preparation method of fast-fired ceramic tiles and its products. A preparation method of fast-fired ceramic tiles comprises the following steps: A. uniformly mixing the raw materials of the green body, and then passing through ball milling to make slurry and drying and granulating A green body powder is obtained, and the green body powder is pressed and formed to obtain a green body; calculated according to mass percentage, the chemical composition of the green body raw material contains K 2 O 4.1~4.5%, Na 2 O 1.3-1.7% and MgO 1.4-1.7%; B. Apply glaze on the surface of the green body; the raw materials of the glaze include potassium feldspar, calcined alumina, kaolin, quartz, dolomite and zirconium silicate. The preparation method of the fast-fired ceramic brick can realize rapid firing in a short kiln, effectively improves the production speed of the ceramic brick, improves the production capacity of the production line, and is conducive to saving energy. The preparation method of the fast-fired ceramic brick The prepared fast-fired ceramic brick has high strength and good quality.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a method for preparing fast-fired ceramic bricks and products thereof. Background technique [0002] The competition of architectural ceramic products is becoming increasingly fierce. Architectural ceramic products have become an important building decoration material. China's ceramic industry has a large output, and kilns are the most critical equipment for ceramic enterprises and also the equipment that consumes the most energy. During the firing process of ceramics The energy consumption accounts for a large proportion of the total energy consumption of ceramic production, and the level of kiln energy consumption is closely related to the raw materials of ceramic bricks and the firing process. The existing rapid firing process of ceramic bricks usually uses long kilns for firing. The length of the furnace itself is sufficient to install enough spray guns. The te...
