Coating classification: photocatalyst

Core tip: Product Introduction: Photocatalyst is a synthetic word of light [photo = light] + catalyst [catalyst] Photocatalyst is a kind of photocatalysis material, which is represented by nanometer titanium dioxide It is the most ideal material to control indoor environmental pollution in the world Photocatalyst under the illumination of light will produce photocatalysis reaction similar to photosynthesis, and produce free hydrogen and active oxygen with strong oxidation ability, which has strong photo oxidation-reduction function and oxidizable component Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: Product Introduction: photocatalyst is the synthetic word of light [photo = light] + catalyst [catalyst] Photocatalyst is a kind of photocatalysis material, which is represented by nanometer titanium dioxide It is the most ideal material to control indoor environmental pollution in the world Photocatalyst can produce photocatalysis reaction similar to photosynthesis under the irradiation of light, and produce free hydrogen and active oxygen with strong oxidation ability It has strong photo oxidation-reduction function, can oxidize and decompose various organic compounds and some inorganic substances, can destroy the bacterial cell membrane and the protein that solidifies virus, can kill bacteria and decompose organic pollutants, and make organic pollution The product is decomposed into pollution-free water (H2O) and carbon dioxide (CO2), so it has strong functions of sterilization, deodorization, mildew prevention, pollution prevention, self-cleaning and air purification Photocatalyst is characterized by using oxygen and water molecules in the air to convert the organics contacted into carbon dioxide and water, which can not change by itself, but can promote chemical reaction Theoretically, it has a very long validity period and low maintenance cost At the same time, titanium dioxide itself is non-toxic and harmless, and has been widely used in food, medicine, cosmetics and other fields Reaction mechanism: when the nano-TiO2 ultrafine particles are irradiated by ultraviolet light with wavelength below 388 nm, the internal part of the nano-TiO2 ultrafine particles will be excited to generate electron hole pairs, i.e photo generated carriers, which will rapidly migrate to its surface and activate the adsorbed oxygen and water, thus producing living free hydroxyl (· oh) and active oxygen (· o ）When pollutants and bacteria adsorb on the surface, the chain degradation reaction will occur Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
