Ultra-thin ceramic external wall brick preparation method
The present invention discloses an ultra-thin ceramic external wall brick preparation method, wherein the adopted raw materials comprise, by weight, 20% of clay, 5% of a binder, 20% of kaolin, 10% of potassium feldspar, 10% of albite, 30% of quartz feldspar tailings, and 5% of lithium feldspar. The preparation method comprises: adding the raw materials and water to a ball mill to carry out ball milling, screening the milled slurry, spraying into a powder material by using a spray drying tower, staling, carrying out dry pressing on the obtained powder material by using a large-tonnage press so as to obtain a billet, placing the obtained billet onto a pad plate through a vacuum adsorber, conveying the billet placed on the pad plate and the pad plate into a roll table kiln, and firing to obtain the ultra-thin ceramic external wall brick. Compared with the ultra-thin ceramic external wall brick in the prior art, the ultra-thin ceramic external wall brick of the present invention has the following characteristics that: the performance is good, the thickness is 4.1-4.2 mm, the weight is 7 kg/m<3>, the water absorption is 0-0.5%, the damage strength is 600 N, and the standard of the Thin ceramic tiles for exterior walls is met.
