A high-rise residential building under construction in Beijing's Wangjing New District recently took a new lease of life: The release of ammonia from a degradable concrete anti-freeze liquid with a nano-modified waterproof coating effectively solved the problem of excessive ammonia.
According to the project's Party A and Party B sources, due to the wrong ratio of antifreeze liquid raw materials, a large amount of ammonia was released from the concrete wall after the completion of the main body of this building, and the ammonia content in the indoor air was seriously exceeded. After many consultations, they cooperated with Beijing Donghai Anti-Corrosion and Waterproof Engineering Company to paint the nano-modified waterproof coating produced by the company in the wall and bathroom. Now it has been painted over 4,000 square meters, and this nanometer reform has been tested by authoritative departments. The waterproof coating degrades the ammonia content by 80% and fully meets the indoor air quality standard.
How can waterproof paint have detoxification function? According to a researcher from Beijing Donghai Company, this waterproof coating is made by nanotechnology after being modified by titanium dioxide. Its characteristics are firstly excellent waterproof performance, and at the same time, it can effectively degrade ammonia, formaldehyde, xylene and other toxic and harmful substances through light and action, thereby playing the role of detoxification.
Beijing Donghai Co., Ltd. is a professional manufacturer of waterproof coatings and rigid waterproof materials for the waterproof industry. Its water-free, JS composite waterproof coatings and pipeline-lined anti-corrosion and waterproof mortar all occupy a large market share. In 2002, they developed a nano-modified waterproof coating developed in cooperation with the Capital Normal University Institute of Advanced Materials to fill the gaps in the domestic market and took the first step in the successful introduction of nanotechnology into the construction waterproofing industry.
