Diatom mud is added to phototalytic technology to solve degradation problems

As an alternative to
coatings
(also known as
paints
"), diatom mud has developed rapidly over the past few years, becoming a mainstream wall material option with paints and wallpapers. In the major home stores, there are new diatom mud wall brand shiny debut, from the other side reflects the market for environmentally friendly building materials urgent needs.
it is said that diatom mud has a more subtle hole-type structure than activated carbon, strong adsorption, not only the material itself is environmentally friendly, can absorb, degrade harmful substances, protect the health and safety of the home environment. But the truth may disappoint, says Zheng Shuilin, a professor at the School of Chemistry and Environmental Engineering at China Mining University. Adsorption is a physical function that does not break down organic matter. Moreover, when saturation adsorption is reached, some of the adsorption gas material will certainly be dissoated under the conditions of changes in room temperature and humidity. This means that if the saturated adsorption is harmful gas, then the harmful gas may be released again. "Formaldehyde is released for more than ten years in harmful gases caused by home decoration or furniture. Therefore, if indoor formaldehyde pollution is seriously exceeded, it is difficult to continuously ensure that indoor air quality is up to standard by the adsorption function of diatom soil or diatom mud alone. Zheng Shuilin said.
does the inability of pure diatom mud to degrade harmful substances mean that even if most of the harmful substances are adsorbed, we have to worry all the time about whether there will be harmful substances re-swinging the problem? It is not necessary, at present, the domestic has developed both adsorption, but also the degradation of harmful gases of diatom mud technology.
Zheng Shuilin, a professor at the China Mining University, led the study of the latest "nano-titanium dioxide diatom soil" technology can make up for the defects of pure diatom mud. The so-called "titanium dioxide" is popularly known as the "optical media" to play the main substance. In short, new technology loads nano-titanium dioxide particles to the surface of diatom particles, making the surface of diatom holes covered with "light media". Diatom soil itself can absorb harmful gases such as formaldehyde, and "light media" in visible light, these harmful substances can be decomposed, thereby degrading harmful substances.
" nano-titanium dioxide diatom soil composite photocatalytic material for powdered products, has been applied to the market. Zheng Shuilin said the material can be used not only as a wall material, but also in wooden shutters, paint, flooring, wallpaper, tiles, curtains and other interior decoration or decorative materials. However, Zheng Shuilin also reminded that the visible light to achieve photo catalytic technology is very difficult, and the country has not yet issued relevant industry standards, consumers difficult to judge the true and false products, only through the relevant testing report for reference.Diatom mud noun interpretation:
diatom mud is a diatom soil as the main raw material of the interior wall environmental protection decorative wall material, with the elimination of formaldehyde, purifying air, regulating humidity, release of negative oxygen ions, fire flame retardant, wall self-cleaning, sterilization deodorization and other functions. Because diatom mud is healthy and environmentally friendly, it is not only very decorative, but also functional, and is an alternative to wallpapers and
latex paint
a new generation of interior decoration materials.
