Problems solved by technology

At present, the degree of treatment and utilization of ceramic industry waste in my country is relatively low, and funds are in short supply, resulting in a large amount of waste slag occupying cultivated land, polluting water and air
Especially in the past 20 years of rapid development, with the increase of output in the ceramic industry, the amount of waste is increasing. According to incomplete statistics: only Foshan ceramic production area, the annual output of various ceramic waste has exceeded 4 million tons, while The annual output of ceramic waste in the country is estimated to be about 10 million tons. The hardness of ceramic waste fired at a high temperature of more than 1,000 degrees is even stronger than that of stone, and it cannot be weathered for thousands of years. Such a large amount of ceramic waste is no longer simply landfilled. The problem that can be solved, and with the increasing economic development and social progress, the environment has become the focus of people's attention. The accumulation of ceramic waste occupies the land and affects the dust content of the local air, while the landfill of ceramic waste consumes manpower and material resources. Pollution of groundwater quality, how to turn waste into treasure and waste into resources has become a top priority for science and technology and environmental protection departments

Embodiment 1

[0045] Break the ceramic waste into particles larger than 0 and smaller than 200 mesh, add 10 kg of bentonite with a particle size of 150 mesh to 90 kg of the above-mentioned granular ceramic waste, and add 5 kg of water to stir to obtain a viscous mixture. at 100pa / mm 2Pressed into permeable bricks under high pressure, fired at 1160-1220 degrees for 28 hours after demoulding.

Embodiment 2

[0047] Crush the ceramic waste into granules larger than 0 and less than 100 meshes and then sieve. Take 95 kilograms of the granules, including 0.95 kilograms (1%) of ceramic waste particles larger than 0 and less than 8 meshes, and 81 kilograms (85%) of ceramic waste particles from 8 mesh to 30 meshes. ), mixed with 13.05 kg (14%) of ceramic waste particles larger than 30 mesh and smaller than 100 mesh, adding 5 kg of bentonite with a particle size of 300 mesh, and adding 3 kg of water to stir to obtain the mixture slurry, adding the above mixture into the mold, and using a press at 90pa / mm 2 The pressure is pressed into permeable bricks, and after demoulding, it is fired at a temperature of 1220 degrees for 26 hours to obtain outdoor ceramic permeable bricks.

Embodiment 3

[0049] The ceramic waste is crushed into granules larger than 0 and less than 100 mesh and sieved, and 92 kg of the particles are taken, of which 3.68 kg (4%) of ceramic waste particles larger than 8 and smaller than 30 mesh, 82.8 kg (90%) of ceramic waste particles of 8 mesh to 30 mesh ), 5.52 kilograms (6%) of ceramic waste particles greater than 30 orders and less than 100 orders are mixed, adding 8 kilograms of bentonite binders with a particle size of 200 orders wherein, and adding 4 kilograms of water to stir to obtain the mixture, adding the above-mentioned mixture in the mould, using Press at 110pa / mm 2 Pressed into permeable bricks under high pressure, fired at a temperature of 1160 degrees for 29 hours after demoulding to obtain outdoor ceramic permeable bricks.

Abstract

The invention discloses an outdoor ceramic water permeable brick which comprises a backing material and a surface layer, wherein the backing material comprises the following components in percentage by weight: 90-95wt% of ceramic waste particles which are crushed to be greater than 0 mesh but smaller than 200 meshes and 5-10wt% of a binder which is bentonite; and the surface layer comprises colored ceramic waste particles which are crushed to be greater than 0 mesh but smaller than 200 meshes and the binder, or a mixture of pigments, ceramic waste particles which are crushed to be greater than 0 mesh but smaller than 200 meshes and the binder; weight of the surface layer accounts for 20% of the weight of the backing material; and the pigments are common ceramic industrial raw materials.

Description

technical field [0001] The present invention relates to an outdoor ceramic permeable brick and its production method. Specifically, the present invention relates to a kind of renewable resource materials such as ceramic waste products and industrial waste slag, which are processed into a specific particle size with a special binder. An outdoor ceramic permeable brick made of calcining inorganic pigments at high temperature and a production method thereof. Background technique [0002] my country is a country with drought and floods. The contradiction between water conservation in arid areas and drainage in rainy areas is extremely prominent. Many towns are covered by reinforced concrete houses, large-scale infrastructure, and various impervious sites and roads. These impermeable sites While the pavement has thermal storage properties, it lacks breathability and rainwater permeability. Reasonably plan the surface rainwater runoff path to minimize surface runoff, and adopt vari...
