[0057] Example 1
[0058] A production process of 16-degree matte marble tiles, including the steps:
[0059] A1. Select raw materials and homogenize ingredients
[0060] B1. The slurry is milled, sieved to remove iron, powdered, and stale in the box;
[0061] The water content of the slurry is 30%, the sieving is a 250-mesh sieve, the sieve residue is 0.3, and the iron content of the sieving to remove iron is 0.2%.
[0062] C1. Pressing, sending the prepared slurry into the press mold, pressing and forming under a pressure of 30000KN, and then drying;
[0063] D1, glaze printing, priming, inkjet printing, screen printing protection, and matte surface glaze are applied on the ceramic tile in sequence;
[0064] The chemical composition of the main raw material for glazing: SiO 2 45%, AL 2 O 3 12%, Fe 2 O 3 0.18%, TiO 2 0.03%, CaO8%, MgO5%, K 2 O3%, Na 2 O2%, BaO9%, ZnO4.9%, IL10.89%;
[0065] E1. Under the condition of a firing temperature of 1250°C, firing for 40 minutes, after edging and ...
