Abstract

The invention discloses a preparation method of a fast-fired ceramic tile and a product thereof. The preparation method of the fast-fired ceramic tile comprises the following steps: A, uniformly mixing green body raw materials, then carrying out ball-milling pulping and drying granulation to prepare green body powder, and carrying out compression molding on the green body powder to obtain a green body, wherein the green body raw materials comprise the following chemical components in percentage by mass: 4.1 to 4.5% of K2O, 1.3 to 1.7% of Na2O and 1.4 to 1.7% of MgO; and B, applying glaze on the surface of the green body; wherein the raw materials of the glaze comprise potassium feldspar, calcined alumina, kaolin, quartz, dolomite and zirconium silicate. According to the preparation method of the fast-fired ceramic tile, fast firing in a short kiln can be achieved, the production speed of the ceramic tile is effectively increased, the productivity of a production line is improved, energy saving is facilitated, and the fast-fired ceramic tile prepared through the preparation method of the fast-fired ceramic tile is high in strength and good in quality.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a preparation method of a quick-fired ceramic tile and a product thereof. Background technique [0002] The competition of building ceramic products is increasingly fierce. Building ceramic products have become an important building decoration material. The output of China's ceramic industry is large, and the kiln is the most critical equipment for ceramic enterprises and the equipment that consumes the most energy. During the ceramic firing process The energy consumption of ceramic tiles accounts for a large proportion of the total energy consumption of ceramic production, and the level of energy consumption of kilns is closely related to the raw materials and firing process of ceramic tiles. The existing fast firing process of ceramic tiles usually uses long kilns for firing. The furnace itself is long enough to install enough spray guns. The temperature transition of...
