How to increase the application of new technologies and environmental protection materials?

Materials are the material basis for human survival and development. In 1970s, people regarded information, materials and energy as "the three pillars of contemporary civilization". Materials are closely related to national economic construction, national defense construction and people's lives. Traditional materials have become new environmental protection materials by adopting new technologies to improve their technical content, save energy and protect the environment.

With the development of scientific research, it is found that when a substance reaches the nanometer scale, its properties will suddenly change, and special properties will appear in the range of 1 ~ 100 nanometer. This kind of material, which is different from the original atoms, molecules and macroscopic substances, is called nano-material.

The application prospect of nano-materials in the future is very broad.

Because of its special surface and structure, nano-materials have excellent properties that ordinary materials can't get. With the help of traditional coating technology, nano-materials are added to the coating, and a new nano-fire retardant coating is added to the top of the National Stadium, so as to enhance the fire resistance and achieve a functional leap, and the traditional coating can be modified to obtain functions that the traditional coating does not have, such as superhard, wear resistance, oxidation resistance, heat resistance, flame retardancy, corrosion resistance and discoloration. Adding nano-materials into coatings can further improve their protective ability and realize the functions of preventing ultraviolet radiation, atmospheric invasion and degradation. When used in sanitary products, it can play a role in sterilization and cleaning. Adding suitable nano-materials into building materials such as glass can reduce light transmission and heat transfer and produce heat insulation and flame retardant effects. Because the colors of oxide nanoparticles and nano stealth materials are different, the color of the coating can be controlled by compounding, which overcomes the monotony of carbon black electrostatic shielding coating with only one color. The color of nano-materials is not limited to particle size, and it has the effect of changing color with angle. In the decorative spraying industry of automobiles, adding nano-materials into the metallic shiny topcoats of automobiles and cars can produce rich and mysterious color effects, thus diversifying the colors of traditional automobile surfaces.

The chemical industry affects all aspects of human life. If nanotechnology is applied to the chemical industry, it will show its unique charm. Nano-materials can play an important role in chemical fields such as rubber and plastics. If nano-silica is added to rubber, the anti-ultraviolet radiation and infrared reflection ability of rubber can be improved; Adding nano-alumina and silicon dioxide into ordinary rubber can improve the wear resistance and dielectric properties of rubber, and its elasticity is obviously better than that of rubber filled with white carbon black. Adding some nano-materials into the carbon nanotube plastic with a magnification of 30 times can improve the strength and toughness of the plastic, and the compactness and water resistance are also improved accordingly. Recently, titanium dioxide for food packaging has been developed. Nano-titanium dioxide can strongly absorb ultraviolet rays in the sun and produce strong photochemical activity. It can photocatalytic degrade beneficial pollutants in industrial wastewater. It has the advantages of high purification, no secondary pollution and wide applicability, and has a good application prospect in environmental protection water treatment.
