Filter paper material
 
Natural fibers, including coniferous wood pulp, broad-leaved wood pulp, longgrass pulp, filter paper generally use blended pulp, appropriately add a little cotton pulp;
 
Chemical fiber; Glass fiber; 2 Filter paper performance
 
Fluffy, fluffy to breathe, density of 0.15 ~ 0.35g/cm3, high alpha fiber.
 
Micropores, small pore size, large number of holes, filtered out fine particles, air flow; hole size was normal distribution, with the following parameters;
 
Maximum pore size; Average pore size;
 
Permeability, under 1mmH2O pressure, air permeability L/m2/min; strength, using burst, stiffness, tensile, tear physical quantity; 3 filter paper structure
 
The filter paper has directionality, the front side of the filter paper is loose, the fibers are loose, the mesh surface of the filter paper is tight, the front pores are flared; the pores are smaller along the thickness of the filter paper; the thickness of the filter paper is about 0.35-0.5 mm, and the dust particle size is From a few micrometers to several tens of micrometers, filter paper filter should not simply understand that only the screen function has the function of depth filtration; side enlargement shows that the filter paper is a multi-layer structure. The front side of the filter paper should face the airflow direction. The filter paper surface should be out of the direction of the gas. On the surface of the screen, a color line should be drawn to facilitate user identification to prevent mistakes. If the wrong direction is used, the filter element is in use, and the dust is stored. 30% reduction in capacity
