High-pressure grouting ceramic slurry based on waste ceramic recycling as well as preparation method and system

Abstract

The invention discloses high-pressure grouting ceramic slurry based on waste ceramic recycling as well as a preparation method and a system. The ceramic slurry comprises the following raw materials: 1-5 parts of quartz sand, 5-10 parts of high-sodium mountain flour, 5-10 parts of potassium albite, 8-13 parts of ball clay, 15-20 parts of kaolin, 15-20 parts of illite clay, 10-15 parts of pyrophyllite, 1-5 parts of dolomite, 10-15 parts of sericite and 5-10 parts of waste ceramic slurry, wherein the grain composition of the waste ceramic slurry is D55 of 0-10 mu m, D35 less than or equal to 5 mum, S70 less than or equal to 20 mu m and D95 less than or equal to 45 mu m. The use amounts of quartz and feldspar in the raw materials are greatly reduced, the production cost of the high-pressure grouting ceramic slurry is lowered, the waste ceramic recycling and utilization rate is up to 5-10 wt%, and environmental pollution can be reduced. Waste ceramic slurry granule distribution is centralized in a position of 10 mu m, defects that a high-pressure grouting ceramic blank is liable to layer, low in blank yield, easy in sintering layer swelling, and the like when being molded since waste ceramic slurry granules are distributed in positions of large particle sizes can be avoided, and high-ratio utilization of waste ceramics can be achieved.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to a high-pressure grouting ceramic slurry based on waste porcelain recycling and a preparation method and system. Background technique [0002] my country is a veritable big country in the production and consumption of ceramics. With the continuous growth of population, urban construction and rapid economic development, a large amount of land has been expropriated, which has led to the increasingly prominent contradiction between man and land in our country. If ceramic sanitary ware companies still smash solid waste into landfills, it will have no impact on the sustainable development of the environment. Not much benefit. Due to the low awareness of waste utilization by many ceramic manufacturers, coupled with technical and cost reasons, the waste porcelain utilization industry cannot expand for a while. The embarrassing situation faced by enterprises is that on the one hand...

Problems solved by technology

Due to the low awareness of waste utilization by many ceramic manufacturers, coupled with technical and cost reasons, the waste porcelain utilization industry cannot expand for a while.

The embarrassing situation faced by enterprises is that on the one hand, solid waste such as waste porcelain is disposed of at will or simply landfilled, and waste porcelain cannot be decomposed naturally during recycling, occupying land and polluting, and destroying the soil structure and causing surface subsidence; on the other hand, Enterprises that have the capacity to regenerate waste porcelain are faced with the dilemma of being unable to fully realize the recycling of waste porcelain due to cost issues.

[0003] The existing high-pressure grouting ceramic slurry formula uses a large amount of raw materials such as illite and quartz, which is high in cost and the slurry suction speed is average. However, waste porcelain can be used as high-pressure grouting ceramic slurry due to its strong water permeability and high strength. However, due to the high hardness and lack of plasticity of waste porcelain, it is easy to cause stratification of high-pressure grouting ceramic slurry, so it is impossible to directly mix waste porcelain into the raw material of high-pressure grouting ceramic slurry, making the recovery of waste porcelain low utilization
