In recent years, many cities in our country have been hit by heavy rain. The road area is severe, the traffic is severely blocked, and even the traffic is paralyzed. It has greatly affected people's daily travel. People once laughed and said, "See the sea." Why is it that the larger the city is, the denser the city is, and the more easily the situation of large-scale water accumulation and traffic congestion occurs? What kind of drainage system does our city need to keep people's normal life?
According to relevant experts, it was because the original rivers and wetlands were gone, and the ground that could have penetrated the water had become impervious cement ground, which damaged the natural drainage system. In order not to prevent the development of the city and keep people's normal life, it is urgent to create a new drainage system to replace the original drainage systems.
It is reported that the product launched by Bosch Cement Products is called "self-cleaning permeable brick ", which can deal with the current urban water accumulation and drainage system problems.
Self-cleaning permeable brick is the first domestic application of photocatalyst technology in concrete permeable floor tiles. Photocatalysts under the illumination of light will undergo a photocatalytic reaction similar to photosynthesis, and the free radicals and reactive oxygen species that are extremely strong when oxidized , Has a strong photooxidative recovery function. It can oxidize and differentiate various organic compounds and some inorganic substances, and differentiate organic pollutants into non-polluting water (H2O) and carbon dioxide (CO2). Therefore, it has strong anti-fouling and self-cleaning, air and water purification functions, useful The problems of simple blockage of pores of permeable floor tiles and pollution to urban soils have been addressed.
According to the developers, in a local air area of 13,000 square meters, using self-cleaning permeable floor tiles, the content of nitrogen oxides can be reduced by more than 45% than before use. In the experiment, we soaked the self-cleaning permeable floor tile with oil to make it not permeable, and then exposed to the sun for a week. The pores opened naturally and began to permeable, and did not cause any secondary pollution together. It accords with ecological principles and respects Law, under the premise of giving priority to ecological functions, adopting appropriate technical measures to optimize the data and structure system of the ground pavement, fully explore the ecological potential and environmental benefits of the water-permeable pavement, and maintain the urban naturalness including the urban ground pavement A virtuous cycle of the ecosystem. Typical urban "psoriasis" chewing gum is generally difficult to remove on the floor tiles, while self-cleaning permeable floor tiles naturally fall off after two weeks.Undoubtedly, the "self-cleaning permeable brick " is now in China's urban drainage system, completely eliminate sewage, dredge traffic after heavy rain, and improve the urban environment has an irreplaceable role. It is hoped that this new research result can be quickly applied to urban construction and thoroughly deal with the problem of urban waterlogging in China.
