Problems solved by technology

Existing wall and floor tiles have the following defects: one, due to Al in its chemical composition 2 o 3 Higher, the crystallization ability of the glass phase formed in the firing process of the green body is stronger, and the light transmittance of the green body is poor after firing, so the wall and floor tiles made have poor light transmittance, poor jade texture, and poor appearance decoration effect. ideal
Second, because Al 2 o 3 If the content is high, the glass phase formed during the sintering process of the green body has high viscosity and weak diffusion ability, and it is difficult for the higher viscosity glass phase to penetrate and fill the pores inside the green body. The water absorption rate is low, so the antifouling property of the green body is poor
3. For ordinary wall and floor tiles, due to the usually selected raw material Fe 2 o 3 +TiO 2 The content is high, and the whiteness of the green body is not high
Therefore, in order to improve the whiteness of the green body and reduce Al 2 o 3 In the prior art, under normal circumstances, one is to introduce a certain amount of quartz, but the addition of quartz should not be too high (usually less than 35%), otherwise the volume will be lost due to the instantaneous crystal transformation of quartz during firing. Expansion, it is easy to generate a lot of stress inside the green body, resulting in cracking and deformation of the green body
The second is to introduce a certain amount (2-10%) of zircon sand (powder) into the green body, but because zircon sand (powder) is radioactive, the wall and floor tiles produced are also radioactive.
At the same time, due to the introduction of zircon sand (powder), the light transmittance and jade texture of wall and floor tiles are also reduced.
