The number of ions in the room increased, especially the number of negative ions increased, and the number of positive ions decreased very much. Comparative Example 1
And 2 and the blank in the room did not change the number of ions. 2) As is clear from the experimental results of Examples 1 to 8 and Comparative Examples 1 and 2, since the building materials of Examples emit negative ions, the negative ions in the room may increase with time. found. 3) As a result of measuring the static electricity of the TV in the room, it became clear that the static electricity charge of Examples 1 to 8 was significantly reduced as compared with Examples 1 and 2 and Comparative Examples 1 and 2. . This phenomenon is presumed to be due to the fact that negative ions are electrodeposited and neutralized and reduced when the television screen is charged with positive static electricity. 4) Effect of ions The number of ions in room air, which is usually considered to be bad for the body in urban areas, is an environment in which there are very few negative ions and very many positive ions, as shown in the above test results. . On the other hand, for example, in an air environment such as around a waterfall or a plateau, there are very many negative ions and very few positive ions. For this reason, it is said that when you go to a place where the air environment is beautiful, such as a plateau, people feel refreshed because of the effect. Especially, in recent years, people's interest in the social environment has been increasing, and in the interior of buildings, which are familiar living environments, the use of various electric appliances also affects the generation of static electricity and electromagnetic waves, Even more so, the current situation is that negative ions are lost and positive ions are increased.
