Production process of water-permeable, air-permeable and air-purifying pavement bricks

Abstract

The invention provides a production process of a water-permeable and air-permeable paving brick capable of purifying air and belongs to the technical filed of transportation facilities. The production process comprises the following steps of adding higher than 10% of high-titanium dry slag into industrial waste slag, coal gangue and zeolite, adding 1% of sodium carbonate and 2.5% of water glass, uniformly stirring, calcining, adding a low-temperature binder, stirring, carrying out compression molding and then calcining into microporous honeycomb with capillary through holes. By the production process, a lot of industrial wastes can be consumed to produce the water-permeable and air-permeable paving brick capable of purifying air, the environmental pollution can be reduced, the large fertile farmland clay is saved, the waste is changed into treasure, harmful substances in the air can be largely absorbed and degraded, the production process is an effective way to achieve efficient utilization of resources and meanwhile, the pollution can be effectively reduced and the air is purified.

Description

technical field [0001] The invention belongs to the technical field of transportation facilities, and in particular relates to a production process of water-permeable, air-permeable and air-purifying pavement bricks. Background technique [0002] my country's air pollution is becoming more and more serious, but because in my country's environmental governance, only water pollution and solid waste governance are highly market-oriented, and the rest, such as air pollution governance, is easily affected by the weather and will be transferred between different regions. Therefore, the government has always been less active in air pollution control, and this part of the market is relatively weak. [0003] Losses caused by air pollution in Chinese cities mainly include: health loss (especially chronic bronchitis) caused by outdoor and indoor air pollution, crop and forest loss caused by acid deposition, material corrosion, high lead content in particulate matter causing neurologica...

[0013] ④Cause acidic rainfall, which will have adverse effects on agriculture, forestry, freshwater aquaculture, etc.

[0015] ⑥It will have an impact on the global climate. For example, the increase of greenhouse gases such as carbon dioxide will lead to warming of the earth's atmosphere, leading to an increase in global weather disasters, and the increase of aerosol particles such as smoke and dust will increase the turbidity of the atmosphere, weaken solar radiation, and affect the earth. Long-wave radiation, causing abnormal weather and climate
