The results show that the concentration of pollutants in indoor confined space is 7-20 times that of outdoor air pollutants. According to the statistics of the National Center for Disease Control and prevention, 2.2 million adolescents die of respiratory diseases caused by indoor pollution every year. Among them, 1 million are children under 5 years old, and the indoor air pollution is 5-10 times higher than that of outdoor pollution.
Relevant experiments have confirmed that negative oxygen ions can play a positive role in improving the ecological and living environment. The small ions in negative oxygen ions can capture floating dust and make it agglomerate and precipitate, so as to purify the air.
Mr. Lin Jinming, academician of the Chinese Academy of Sciences and doctoral advisor of Tsinghua University, said that the content of negative oxygen ions in the air is directly proportional to the number of plants. In places with dense plants, the content of negative oxygen ions is usually higher, and there are large differences in the content of negative oxygen ions in different environments.
● 10000-20000 pieces / cm3 in forest and waterfall area, with natural healing power.
High mountain and seaside 5000-10000 pieces / cubic centimeter, bactericidal effect, reduce the spread of disease.
It has the function of enhancing human immunity.
Urban parks are 200-1000 / cm3, which is essential for maintaining health.
0-50 pieces / cubic centimeter in urban residence, which is easy to cause physiological discomfort.
The content of negative oxygen ions is an important indicator to judge whether the air is fresh or not. The environmental protection department points out that when the concentration of negative ions reaches 1000-1500 per cubic centimeter, it is judged as fresh air.
With the popularization of green environmental protection and low-carbon life concept, consumers pay more attention to green environmentalists and improve their quality of life. As the last link of home decoration, the beauty seam will not only affect the decorative effect of ceramic tiles, but also affect the quality of indoor air.
