MEASUREMENT OF CHEMICAL COMPOUNDS EMITTED FROM THE FLOOR CONSTRUCTED VARIOUS KINDS OF PVC FLOORINGS

The purpose of this study is to clarify the relationship between diffusive character of 2-ethyl-1-hexanol (2E1H) in flooring finish material and 2E1H emission rate from floor surface. The 2E1H emission flux in various flooring finish material is measured and an effective diffusion coefficient of 2E1H for the material is calculated from the emission flux. Some flooring finish materials are attached on top of subfloor materials with adhesive, and these 2E1H emission rates are measured. It is clarified that 2E1H emission rate from floor surface is high, when the effective diffusion coefficient of 2E1H for the flooring finish material is high.
