What are the four major effects of nano-materials and their practical meanings? 10 1. surface effect refers to the change in properties caused by the sharp increase of the ratio of nano-particle surface atoms to total atomic numbers with the smaller particle size.Table 9-2 The relationship between the size of nanoparticles and the number of atoms on the surface is given.With the decrease of particle size,The number of atoms on the surface increases rapidly.In addition,With the reduction of particle size,The surface area and surface energy of nanoparticles are rapidly increasing.This is mainly the smaller the particle size,The more atoms are on the surface.The crystal field environment and binding energy of surface atoms are different from those of internal atoms.There is a lack of adjacent atoms around the surface atoms,There are many dangling keys,With unsaturated properties,It's easy for other atoms to settle down if they want to combine,Therefore, it shows great
What kind of place will do well water filtration equipment? What is the role of general well water filtration equipment? There are many iron and manganese elements and fluorine in the well water. drinking such well water for a long time will have serious harm to the human body.You must pass the well water filter before you can drink it.What is the process of well water filter? The following is a specific description.1. quartz sand filter.The raw water is sent to the quartz sand filter through the slurry pump to remove the sediment, rust, large particles, suspended substances, algae and other harmful substances in the water.2. activated carbon filter.The adsorption capacity of activated carbon is relatively strong.Activated carbon can absorb residual chlorine and odor in water, which shows the importance of activated carbon filter.3. water softener.The hardness of well water is relatively large. after the treatment of the water softener, the hardness of the water can be reduced, the calcium and magnesiu
