Embodiment 1
[0044] A method for preparing a matte glazed high three-dimensional simulated ceramic brick, comprising the following steps:
[0045] Step 1: SIGMA200-300 laser four-dimensional engraving equipment is used to carve patterns on the mold surface of the master mold. The height difference of the finely carved patterns on the mold surface reaches 2.5mm, and the radian of the depth transition of the mold surface is R8. like figure 2 As shown, at the same time, the mold opening is a positive pressure mold, and the back grain is a straight stripe so that the positive pressure pushes the blank out of the mold. figure 1 It is an enlarged view of the digital laser four-dimensional fine carving file of Embodiment 1.
[0046] Step 2, adopt common adobe raw material formula known in the art for batching, generally by potassium feldspar, albite, talc, quartz, kaolin, mud, bentonite, alumina, etc., in terms of mass fraction, its chemical composition can be 65-70 parts of silicon dioxide, 1...
Embodiment 2
[0056] A method for preparing a matte glazed high three-dimensional simulated ceramic brick, comprising the following steps:
[0057] Step 1: Use SIGMA200-300 laser four-dimensional fine carving equipment to carve patterns on the mold surface of the master mold. The height difference of the finely carved patterns on the mold surface reaches 2.5mm, and the radian of the transition between the depth and depth of the mold surface is R20. At the same time, the mold opening is open Positive pressure mold, the back grain is straight stripes to facilitate the positive pressure to push the blank out of the mold.
[0058]Step 2: adopt common adobe raw material formulas known in the art for batching, and the powder is pressed through a molding press with a pressure of 300 kg / cm2 to form the green body, so as to control the strength, deformation and poor forming of the green body; The residual billet powder on the billet surface affects the design of the three-dimensional effect, elimina...
Embodiment 3
[0067] A method for preparing a matte glazed high three-dimensional imitation porcelain tile, comprising the following steps:
[0068] Step 1. Use SIGMA200-300 laser four-dimensional fine carving equipment to carve patterns on the mold surface of the master mold. The height difference of the finely carved patterns on the mold surface reaches 2.5mm, and the radian of the transition between the depth and depth of the mold surface is R8. Positive pressure mold, the back grain is straight stripes to facilitate the positive pressure to push the blank out of the mold.
[0069] Step 2: adopt common adobe raw material formulas known in the art for batching, and the powder is pressed through a molding press with a pressure of 300 kg / cm2 to form the green body, so as to control the strength, deformation and poor forming of the green body; The residual billet powder on the billet surface affects the design of the three-dimensional effect, eliminating the damage caused by the relative fri...
