Why do nano-materials have excellent performance? The structure determines the nature!!Due to the outstanding surface effect, small size effect and quantum confinement effect of nano-sized substances,Therefore, nano-materials have optical, electrical, magnetic, thermal, mechanical and other properties different from ordinary materials.Nano-particle materials are also called micro-particle materials,Consists of nanoparticles (nano particles.Nanoparticles are also called ultra-fine particles,Generally refers to the size of 1 ~ Particles between 100nm,It is a transitional area at the junction of atomic clusters and macro objects,From the usual point of view on the micro and macro,Such systems are neither atypical nor typical macro systems,It is a typical system in the middle of,It has surface effect, small size effect and macroscopic quantum tunnel effect.When people subdivide macro objects into ultra-micro particles (nano-scale,It will show many strange features,That is, its optical, thermal, electrical, magne
3 M air purification technology for air purification At present, the removal technology of particulate matter in Air mainly includes mechanical filtration, adsorption, electrostatic dust removal, negative ion and plasma filtration and electrostatic resident filtration.Mechanical filtration generally captures particles in the following three ways: direct interception,Inertia collision,Brown diffusion mechanism,It has a good effect on the collection of fine particles but has a large wind resistance,In order to achieve high purification efficiency,The filter element needs to be dense and replaced regularly.Adsorption is the use of large specific surface area and porous structure of the material to capture particulate pollutants,Easily blocked,The removal effect of gas pollutants is more significant;Electrostatic dust removal is a dust collection method that uses high-voltage electrostatic field to ionize the gas so that the dust particles are charged to the electrode,Although its wind resistance is small, it has
