Study On Indoor Functional Materials Releasing Negative Ions

The paper has focused on the development of functional materials in domestic and abroad especially the development of building materials. The pollution brought by functional materials and the demands for high-qualified life are also illustrated. The benzedrine dope was modified with natural Heath functional additives. The modified dope was able to release anions and to improve ecotype environment for human beings.The benzedrine dope was modified with nano-particles to prepare ecotypic and healthy dope. The XRD, SEM, TEM and anti-bacteria testing were performed on Health-modified benzedrine dope to analyze the chemical properties, structure, properties and routine performances upon application. The results show that valence-variable Fe atoms locate in Health, producing micro-electric field. As water molecules pass through Health holes, they are dissociated into H+ and OH-. H+ ions with positive charge function with each other, and anions remained. TiO2 contained in Health break down organic substance into CO2 and H2O due to phonic-catalytic effects, fundamentally killing bacteria and virus. Some holes with size of 20-60 nm exist in Health. The optimum nano-additives content is m(CaCO3): m(ZnO): m(Anion) = 2:2:3. The modified benzedrine dope showed excellent anti-bacteria functions to golden staphylococcus, E. coli, Candida alb cans and B. subtitles, and the anti-bacteria ratio is more than 90% even after 50 times water bath. When 3% additives are added, the benzedrine dope achieves national standard and released 1700 anions/cm3, meeting demands for human health.
