preparation example Construction

[0040] Specifically, the preparation method of described rock ore dry grain comprises the steps:

[0041] S1. Crushing and granulation: the rock ore is crushed by a crusher, and the particle is classified by a vibrating screen after crushing to obtain a dry semi-finished product of the rock ore;

[0042] S2. Purification treatment: perform purification treatment on the semi-finished rock ore dry granules;

[0043] S3. Classification and sieving: the purified material is classified through a double-layer vibrating sieve to prepare diagenetic ore dry particles.

[0044] In the present invention, the rock ore is selected from corundum, malachite or mica.

[0045] When the rock ore is mica, the purification treatment is calcination and iron removal treatment, wherein the calcination temperature is 1200°C-1240°C. Mica has a flake structure, glass luster, and has a strong reflection effect on light. After the mica dry particles are calcined together with the ceramic body powder, t...

Abstract

The invention discloses dry particles for a ceramic exterior wall brick and a ceramic exterior wall brick containing the dry particles. The dry particles are glaze dry particles or rock ore dry particles, wherein the glaze dry particles comprise the following components in percentage by weight: 57% to 62% of SiO2, 17% to 20% of Al2O3, 5% to 7% of Na2O / K2O, 7% to 9% of CaO, 0% to 3% of ZnO, and 4%to 6% of ZrO2.The preparation method of the rock ore dry particles comprises the following steps: S1, carrying out crushing granulation, namely crushing rock ore by a crusher, performing particle classification through a vibrating screen after crushing to obtain semi-finished products of the rock ore dry particles; S2,performing purification treatment, namely purifying the semi-finished products of the rock ore dry particles; and S3, grading and sieving, namely performing the particle classification on purified materials through a double-layer vibrating screen and preparing into the rock ore dry particles. By adopting the dry particles for the ceramic exterior wall brick and the ceramic exterior wall brick containing the dry particles provided by the invention, the exterior wall brick hasa unique decorative effect of star shapes, sandstone textures, glittering and the like and further enriches product types of the exterior wall brick.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to dry granules for ceramic exterior wall bricks and ceramic exterior wall bricks containing the dry granules. Background technique [0002] Ceramic exterior wall tiles are mainly used for decoration and protection of building exterior walls. With the continuous improvement of people's living standards, the requirements for the decorative effect of ceramic exterior wall tiles are also getting higher and higher. Ceramic exterior wall tiles are not just a product. More often, it is regarded as a work of art by consumers, which can endow the building with unique personality and aesthetics, and fully show the gorgeous coat of the building. However, the decorative effect of traditional ceramic exterior wall tiles is mainly to give the exterior wall tiles different shapes and colors. The decorative effect is relatively simple, and its appearance is not attractive, which can no ...
