With the advent of summer, ozone has gradually replaced smog and has become the “number one killer” of air quality in Xi’an. Especially in recent years, the number of days of air pollution caused by ozone pollution has increased. In 2014, the air pollution caused by ozone in our city was only 8 days, and in 2015 it increased to 21 days. In 2016, ozone caused 37 days of pollution, and in 2017, there were 61 days of pollution. The main cause of excessive ozone pollution is the secondary pollutants formed by nitrogen oxides and volatile organic compounds under the action of high temperature and strong light radiation.

The control of volatile organic compounds in the construction industry mainly involves outer wall coatings, internal wall coatings, waterproof coatings, floor coatings, construction anticorrosive coatings, adhesive products, and road marking marking materials used in municipal projects. In order to minimize ozone pollution, the city launched the control of the use of volatile organic compounds during the “summer protection period”, and specially issued the “Special Treatment Implementation Plan for Construction and Road Painting Operations”, requiring the use of water-based paints for internal and external walls of civil buildings. Coatings, obsolete paints are restricted, and the use of solvent-based paints is strictly prohibited. paint coatings spraying operations are prohibited on construction sites in the city.

According to Chang Junning, a staff member of the Xi’an Building Decoration Industry Management Office, the reason why water-based paint is required to be mandatory on the site is because the water-based paint construction process must be painted on the wall with a gray knife instead of spraying, so it will not produce volatility. Organic matter will not pollute the atmosphere.

The reporter learned that from July 1st, the construction administrative departments of our city will check and accept the materials used on the construction site, focusing on the inspection of illegal and illegal operations, and found that there are any paints that do not meet the standard requirements or are prohibited from sale in our city.

If the problem is serious, work shall be suspended for rectification in accordance with regulations, and a fine of 20,000 yuan up to 200,000 yuan shall be imposed in accordance with the “Law of the People’s Republic of China on the Prevention and Control of Air Pollution.”
