Study on Clay Wall Finishing Materials Added Interior Environment Control Function

Part 2. Absorption characteristics of formaldehyde

Abstract

Recently, houses are insulated and airtight. In consequence, rooms are very humid, which cause condensate. However, the air in rooms is often very dry. Besides, sick building syndrome caused from chemical emitted from building materials and furniture is viewed with suspicion. So it is important for building materials to disinflate interior air pollution. The purpose of Part 1 study was to examine the moisture absorption-release properties of clay wall finishing materials mix in water absorptivity resin. The purpose of this study is to examine reduction effect of formaldehyde.
