Coating knowledge: building exterior wall coating

Core tip: a new type of building exterior wall coating invented in the UK can decompose harmful substances in the air As an experiment, the ecological coating will be widely used in Italy in March this year The paint developed by Millennium chemicals first absorbs and then decomposes nitric oxide, which is a by-product of combustion of mineral energy, and also a substance often contained in automobile exhaust gas and smoke The center of the new coating is a layer of titanium dioxide with a thickness of about 30 nm The titanium dioxide layer can absorb the sun's ultraviolet rays, and the resulting electric charge will make the nitric oxide on its surface occur Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint House News: a new type of building exterior wall paint developed in Britain can decompose harmful substances in the air As an experiment, this ecological paint will be widely used in Italy in March this year The paint developed by Millennium chemicals first absorbs and then decomposes nitric oxide, which is a by-product of combustion of mineral energy, and also a substance often contained in automobile exhaust gas and smoke The center of the new coating is a layer of titanium dioxide with a thickness of about 30 nanometers The titanium dioxide layer can absorb the sun's ultraviolet rays, and the resulting charge will oxidize the nitric oxide on its surface and turn it into nitric acid Nitric acid can also be neutralized by calcium carbonate particles contained in the coating, or washed off directly by rain water 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,
