Description

More recently, with the activation of volcanoes, recycling of volcaniclastic materials are required. In Japan, which has a climate of high temperature and humidity or low temperature drying, improvement of living environment comfort is required not only from building facilities but also from building materials. This paper investigated enhancing the pore structure of volcanic ash, applying electrostatic powder coating to interior finishing and use of volcanic ash as powder electrostatic coating. The summaries of the results are as follows; 1.　Volcanic ash can be expected to become porous by acid decomposition. There is a possibility that the pore structure can be controlled by the method of acid decomposition. 2.　Non-conducting building materials can be electrostatically coated with magnetic paints, indicating the applicability to building rooms. 3.　By mixing volcanic ash and powder paint, electrostatic powder coating that can be expected to have a humidity control function becomes possible.
