What material is filter cotton in smoke alarm system? Difference in material,Filter cotton is mainly based on acrylic fiber,Biochemical cotton is mainly based on foamed plastic polymer.The difference in use,The filter cotton is mainly based on physical filtration,Biochemical cotton is mainly based on biological filtration.The difference in usage,Filter cotton for front end,Wash frequently,Biochemical cotton should not be cleaned frequently for the back end.

What are the simple filter rules? Particle dust is used as inertia movement in the air flow,When you encounter messy fibers,Airflow changes direction,Particles deviate from the direction due to inertia,Hit the fiber and bond.The bigger the particles, the easier it will hit,The better the effect.Small particles of dust do irregular brown motion.The smaller the particles,The more intense exercise without rules,The more chances of hitting an obstacle,The filter effect of efficient filter will also be better.The air is smaller than 0.1 micron particles are mainly used for Brown motion,Small particles, good filter filtering effect.Greater than 0.3 micron particles are mainly used for inertial motion, and the larger the particles, the higher the efficiency.Dust particles in the air,Moving with the flow of air as an inertial motion or irregular brown motion or by a certain field force,When particles move into other objects,Van der Huali, which exists between objects (the force between molecules and molecul
