Abstract
The diatomite was used as the main material,diatomite-based porous ceramics were prepared.On the surface of diatomite-based porous ceramics,through dipping glaze composed by diatomite,tourmaline and sintering additives,tourmaline modification diatomite-based interior wall material was prepared.The formaldehyde removal effect was discussed.The results indicated that the main crystalline phases of tourmaline modification diatomite-based interior wall material were quartz and corresponding tourmaline phase.The material had larger specific surface area and abundant pores.The environmental performance of tourmaline in the glaze was preserved.The concentration of formaldehyde droped from 0.312 mg/m3 to 0.089 mg/m3 in 1 m3 environmental chamber in 360 min,and the formaldehyde removal rate was 71.4%,indicating that the material had good adsorption and removal effects on formaldehyde in indoor air.
