www.greenmillennium.com Nano TiO2 Photocatalyst Coating Technology:
The principle of TiO2 ( Titanium Dioxide ) photocatalytic reaction was to accelerate the nature's cleaning and purifying process using light as energy. Discovered in 1960's, Dr. Fujishima of Japan found titanium metal, after irradiated by light, could break water molecule into oxygen and hydrogen gas. By restructuring titanium dioxide particles in nano-scale, a number of new physical and chemical properties were discovered. One of these newfound effects was photocatalytic oxidation which accelerated the formation of hydroxyl radical, one of the strongest oxidizing agents created by nature. Using energy found in the UV light, photocatalyst titanium dioxide could breakdown numerous organic substances such as oil grime and hydrocarbons from car exhaust and industrial smog, volatile organic compounds found in various building materials and furniture, organic growth such as fungus and mildew. In addition to its photocatalytic oxidation effect, titanium dioxide coating also exhibited hydrophilic property (or high water-affinity) which titanium dioxide coating attracted water moist in the air to form an invisible film of water. This thin film of water allowed the substrate to be anti-static so the coated surface could be easily cleaned by rinse of water. For years, titanium dioxide was used in many commodity products such as paint, cosmetics, sun blocks, and etc. It is a safe and stable substance commonly found in our lives. Numerous applications have been developed from utilizing photocatalytic reaction:
Self-Sanitizing Surface: Photocatalyst coating is considered by many institutions as Hygienic Coating to reduce bacteria and virus contamination. This special coating removes the organic matter necessary for bacteria growth. The strong oxidation mechanism also eliminates any bacteria by causing lesion of cell membrane and lysing of cell content. The toxic remains were eventually oxidized into harmless substance such as carbon dioxide and water.
Self-Cleaning Coating: Building's exterior surface can be benefited from this special coating by eliminating any contaminants that was causing building to become dirty such as the oil content from car exhaust and any mold or mildew stain.
Reduce Indoor Air Pollution and SickBuilding Syndrome: Photocatalyst coating and products controls Sick Building Syndrome by removing Volatile Organic Compounds emitted from building material and furniture and creates a purer space for comfortable living and working condition.
Reduction of Air Pollution: Photocatalytic oxidation reduces hydrocarbon waste produced from industrial factories burning fossil fuel or coal. It is considered as the "Holy Grail" of environmental protection according to many research scientists.
Waste Water Treatment: Photocatalyst can replace chlorine to be more effective and much safer alternative oxidation methods to water purification. Photocatalytic oxidation can remove bacteria, organic toxins, dioxins, and other chemicals in our water system without introducing other chemical.
The causes of exterior wall soiling can be divided into two categories: adhesion of dust and grit caused by static electricity, and adhesion of atmospheric pollutants (exhaust gasses, factory smoke, etc.) due to their oil content. Photocatalyst TiO2 coating's hydrophilicity creates a layer of water on the exterior wall surface to prevent static electricity and attraction of dust, grit, dirt or soot to settle on the surface. In addition, the decomposition strength of the exterior surface weakens the adhesiveness of oil content in organic matter. Any residual dust particles are then washed away by natural rainfall and therefore completing the building's self-cleaning cycle.
Green Millennium Inc. Nano-TiO2 Photocatalyst coating solution demonstrates superior photocatalytic oxidation and super-hydrophilic properties. A building's aesthetic value is greatly enhanced while the overall maintenance is dramatically reduced thus bringing lower life-cycle costs. In addition, the decomposition property of photocatalytic surface cleans up air pollutants in the air stream. Studies have shown smog concentration was reduced by 65 percent on areas coated with photocatalyst titanium dioxide coating. Expansion of the use of photocatalyst technology and products will respond to society's needs for environmental protection, enhanced aesthetic value and longer life spans for all building accessories and materials.
