Study On Radon-Prevention & Radial-Prevention Mortar/Putty/Composites Functional Coating And Composites

The writer had investigated the functional element materials of radon-prevention & radial-prevention , element materials of far infrared , radon-prevention & radial-prevention building materials , integrative preoperational flow of environment functional coating and radon-prevention & radial-prevention mortar/putty/composites functional coating.The research results as flow:(1) Functional element materials of radon-prevention & radial- prevention: (1)Identify and prepare functional element materials of radon-prevention & radial- prevention, These mainly include: barite, zeolite, aluminates cement, gypsum, lime, etc. (2)The results indicated that: the size of Barite & Zeolite crushed via stirred mill (wet-method) and jet pulverizer (dry-method) within a certain time can reach d90, smaller than 10μm. The radon-proof and radiation-protection rate of putty went up 20%. Meanwhile, capability of radon-proof can be enhanced 20% by acidification of zeolite. (2) Functional element materials of far infrared: (1)cordierite far infrared ceramics can be gained in system of Al₂O₃ after joined medical stone, (2)the main crystal phases are MnFe₂O₄, Mn_0.983Fe_0.017O₃ and TiO₂ in system ofFe₂O₃,disfigurement of Mn_0.983Fe_0.017O₃ can be filled by Zr⁺⁴, Ti⁺⁴. (3) temperature effect of far infrared on the element materials is apparently, The temperature of representative samples increased 48.2 °C,51.3°C,69.6°C and 63.7°C respectively in 10min, and infrared radiation rate was up 0.83, 0.86, 0.91, 0.88 separately.(3) Radon-prevention & radial-prevention building materials: (1)the ratio of radon-prevention of composite mortar of radial-prevention& radon-prevention is 70%; the screen ratio of γ-ray is 46.9%. (2)compared with common putty wall surface, the ratio of radon-prevention of composite putty wall surface of radial-prevention& radon-prevention is 86.5% and the ratio of anti-radioactivity is 48.4%, when wt% of functional element materials is to 20% in the composite putty wall surface. (4) Integrative preoperational flow of environment functional coating: (1) the excellent functional coating can be prepared with integrative preoperational flow of environment functional coating. Antibacterial circle wide reach 10-12mm and...
