Features: 1, PPC nanocomposite purification materials, its main function is a long-term adsorption and decomposition of formaldehyde in indoor air, the material in the sunlight and ultraviolet light have good photocatalytic properties. 2. Efficient: nano Tio uniform load to the meerschaum, the uniform distribution of decomposition and adsorption ability, while absorption edge decomposition?. 3, the long-term: Edge adsorption edge decomposition, and then re-adsorption decomposition, to break down long-term goal. 4, odor: diatomaceous earth itself absorption features, remove the odor is not a problem. Consumption usage: 20g / square meter of water after soaking join diatom mud, paint and other interior wall paint stir, then brushing the wall. Scope: diatomaceous earth: in diatomite add PPC nanocomposite purification materials in accordance with 20 grams / square meter of proportion, stirring fully into indoor air in addition to formaldehyde diatom mud, the final product is coated on the surface of the wall, to long efficient decomposition of formaldehyde in indoor air function. Interior paint: in interior paint to add PPC nanocomposite purification materials, indoor air agitation fully made in addition to formaldehyde coatings, product brushing the surface of the wall finally reached in accordance with 20 grams / square meter of indoor air ratio of long-term decomposition formaldehyde function. Wallpaper: Wallpaper production process, in printing inks add PPC nanocomposite purification materials in accordance with 20 grams / square meter of the ratio, the use of the ink can be made in addition to formaldehyde in indoor air wallpaper, products used in indoor and after, can achieve long-term decomposition indoor function of formaldehyde in the air. Wooden blinds: Wooden blinds production process, the use of 20 grams / square meter of proportion to add PPC nanocomposite materials at purifying indoor air formaldehyde UV wear-resistant finish, and finally use the paint roller once, so surface wear, hard, scratch, smooth, flat, flame, and have long-lasting functional decomposition of formaldehyde in indoor air. High-density printed floor: high-density printed flooring production process, the use of 20 grams / square meter of proportion to add PPC nanocomposite materials at purifying indoor air formaldehyde UV wear-resistant finish, and finally use the paint roller once, so surface wear, hard, scratch, smooth, flat, flame, and have long-lasting functional decomposition of formaldehyde in indoor air. Decking: decorative plate production process, using a 20 g / m proportion to add PPC nanocomposite materials at purifying indoor air formaldehyde UV wear-resistant finish, and finally use the paint spraying once, so that the surface wear, hard , scratch, smooth, flat, flame, and have long-lasting functional decomposition of formaldehyde in indoor air.
