What is the filter principle of efficient filter? 1.Interception effect: When a particle of a certain particle size moves near the surface of the fiber,The distance from the center line to the surface of the fiber is less than the particle radius,Dust particles will be intercepted by filter fiber and deposited.2.Inertia effect: when the mass of particles is large or the speed is large,It is deposited by collision on the surface of the fiber due to inertia.3.Diffusion effect: the particle Brown with small particle size moves strongly and easily collides on the surface of the fiber.4.Gravity effect: when particles pass through the fiber layer,Deposited on the fiber due to gravity settling.5.Electrostatic effect: both fibers and particles can bring charge,Generate electrostatic effects that attract particles,And suck the particles onto the surface of the fiber.As more dust is captured,The filtering efficiency of the filter layer also decreases,And the resistance increases;When a certain resistance value
Development history, development status and modern use of soda ash industry [Molecular weight] 105.[Common name] block alkali, Soda alkali, Soda (Soda) and oral alkali (historically,It is generally transferred across the country through Zhangjiakou and Gubeikou,Therefore, there is a saying of 'oral alkali.), Alkali surface (edible alkali), the industrial name of Crystal-free water is light alkali,The industrial name of a crystal water is heavy alkali .'CAS number' 497-19-[Relative density (water = 1)] 2.[Classification] strong alkali weak acid salt * note * (soda ash is not alkali,It's salt![Chemical properties] 1) The solution is alkaline,Can produce a certain reaction with acid.2) reaction of sodium carbonate with alkali.No reaction to sodium carbonate.3) the reaction of sodium carbonate, sodium chloride and salt.Sodium carbonate BaCl2 = bacco
