主　　题：diatomite tourmaline/diatomite-based interior wall tiles glaze layer heat treatment temperature formaldehyde adsorption and degradation 

摘      要：With the improvement of people’s living standards,a large number of petroleum products,daily necessities and decorations that can produce volatile organic compounds are used in decoration,which seriously affects the indoor air *** decoration materials have become a research hotspot in recent *** purpose of this paper is to develop a kind of interior wall material with good indoor formaldehyde removal effect,easily using,and low *** this paper,combining different heat treatment temperatures of the glaze layer,tourmaline/diatomite-based interior wall tiles were prepared by ultrafine grinding,solid sintering,and low temperature *** glaze layer under different heat treatment temperatures was characterized by thermogravimetric-differential thermal analysis,X-ray diffraction,and scanning electron *** influences of heat treatment temperature on the microscopic morphology and structure of the glaze layer were *** formaldehyde as the target degradation product,the effects of tourmaline/diatomite-based interior wall tiles on the removal of formaldehyde under different heat treatment temperatures of the glaze layer were *** results showed that with the increase in heat treatment temperature,the original pores of diatomite decreased,the specific surface area decreased,and the structure of tourmaline *** 850℃,the surface structure of the material was slightly damaged,the strength was increased,and the removal effect of formaldehyde was *** a 1 m^(3) environmental chamber,the formaldehyde removal rate reached 73.6%in 300 *** the temperature was increased to 950℃ and above,diatomite and the structure of tourmaline were destroyed,and the ability of the material to adsorb and degrade formaldehyde decreased.
