Abstract

The invention discloses a method for producing super white ceramic tiles by use of granite waste slurry and belongs to the technical field of waste recycling. According to the method, the granite waste slurry is adopted to take the place of partial traditional raw materials such as feldspar and quartz, and the super white ceramic tiles are produced by use of the production processes of granite waste slurry pretreatment, material proportioning, ball milling, pulverizing, pressing, firing and the like. The method for producing the super white ceramic tiles by use of the granite waste slurry is capable of realizing the changing of the granite waste slurry into things of value; the pollution of the granite waste slurry on the environment is reduced and the granite waste slurry is thoroughly utilized. In addition, the product super white ceramic tiles produced by use of the method are high in quality, and beautiful, smooth and clean entirely; besides, compared with the traditional methods of taking potassium, sodium and aluminum rock flour exploited from the potassium feldspar deposit as the raw material, the method has the advantages of low cost, rich raw material resources, low environmental pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of waste recycling, and in particular relates to a method for producing ultra-white ceramic tiles by using waste granite slurry. Background technique [0002] Granite slab is a high-quality building material, which is widely used in masonry and decoration of high-end and luxurious buildings and structures. With the development of modern buildings, the demand for granite slabs has increased rapidly, further driving the mining and processing of granite. During the processing of granite, a large amount of stone slurry is produced, which contains a large amount of non-metallic minerals such as silicon, potassium feldspar, albite, alumina, etc., and is the top raw material for the production of ceramics. However, usually granite processing plants directly discharge the stone slurry as waste slurry, which not only pollutes the local environment, but also causes a serious waste of resources. [0003] Ultra-white ...
