Selection of diatom mud: analysis of diatom mud adsorption function enables you to understand diatom mud more clearly

Core tip: diatom mud is more and more popular with consumers, and becomes the favorite of the household wall material industry Diatom mud has many advantages, "adsorption and decomposition of formaldehyde" is undoubtedly its biggest bright spot Then, why can diatom mud absorb and decompose formaldehyde? Next, we will explain why diatom mud has adsorption function from three aspects Diatomite adsorption function analysis enables you to understand diatomite more clearly First, the porosity of diatomite is 5000-6000 times that of activated carbon According to relevant data, the porosity of diatomite is 5000-6000 times that of activated carbon, so its unique micro Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: diatom mud is more and more popular with the majority of consumers, and becomes the favorite of the household wall material industry Diatom mud has many advantages, "adsorption and decomposition of formaldehyde" is undoubtedly its biggest bright spot Then, why can diatom mud absorb and decompose formaldehyde? Next, we will explain why diatom mud has adsorption function from three aspects The analysis of diatomite adsorption function enables you to have a better understanding of diatomite (the picture comes from the network) First, the porosity of diatomite is 5000-6000 times that of activated carbon According to relevant data, the porosity of diatomite is 5000-6000 times that of activated carbon, so its unique microporous structure has extremely strong physical adsorption performance and ion exchange performance The adsorption potential of the pores is formed by the attraction of diatom and adsorbed molecules The smaller the pore size is, the stronger the adsorption potential is The diatom mud background wall is an excellent model Second, the theory of molecular motion (1) all objects are composed of molecules or atoms, and there are gaps between them; (2) molecules (atoms) are in a state of thermal motion that never pauses and has no rules, and they collide with each other frequently Under the standard condition, the free movement speed of formaldehyde molecules is 450 m / s, and one formaldehyde molecule collides with other molecules 109 times / s per second (billions of times); If the molecular density of formaldehyde close to the studied surface is equal to that of formaldehyde in the distance at all times, about 2.7x1027 formaldehyde molecules (about 130 kg) collide on the area of each square meter per second; ③ there is mutual force between the molecules, usually expressed as gravity Thirdly, the diameter of collision molecules and the pore diameter of diatom should match If the molecular diameter is larger than the pore diameter, when the molecule touches diatom molecules, it will not enter the pores and be bounced back into the air If the molecular diameter is far smaller than the pore diameter, even if the molecule touches the pores, it will be able to run out The larger the pore diameter, the greater the probability of running out, and the smaller the adsorption rate; When the molecular diameter is a little smaller than the pore diameter, it is difficult for the molecule to run out when it touches the pore, that is to say, it is adsorbed The more molecules are adsorbed, the stronger the adsorption ability is As long as the pore diameter is more than 0.45nm and less than 2.0nm, the toxic and harmful gases can be absorbed by the micropores However, these micropores of diatom molecules account for more than 70% of the total pores, so the diatom mud background wall is the most ideal for the adsorption of these toxic and harmful gases The above is the analysis of three aspects of the adsorption function of diatom mud, hoping to help you understand diatom mud more clearly!
