The technical indicators of filter paper
2017-05-10 View：
The main technical index of the filter can be divided into two aspects, one is the filtration characteristics
of the filter paper, on the other hand, is a physical property.
Filtration characteristics including porosity, maximum pore size and
average pore size. The physical properties including quantitative,
thickness, stiffness, bursting strength, resin content and so on.
Quantitative: Refers to the quality of the filter paper per square meter, unit: g/m2 
Thickness: the thickness of the filter paper does not include the depth of the corrugated. Unit mm
Resistance: the
resistance of filter paper to air flow. The pressure drop value of the
product is expressed in 85 minutes by a 100cm2 filter paper in a minute.
The unit is mbar. or the height of the water column
Corrugated depth: to
strengthen the longitudinal stiffness of the filter paper and suppress
the depth of the trench, the unit is: mm. in general the value of 0.2mm
Air permeability: in a certain area, a certain degree of vacuum, the amount of air through the filter paper per unit time
Maximum aperture: the maximum diameter of the sphere that can pass through the filter paper. Unit: M
Average pore size: the diameter of the hole is calculated by the "burst" bubbling pressure. The unit is m
Resin content: resin as a percentage of the weight of the filter paper
Stiffness: filter paper deformation capacity. Unit: mg
Bursting strength: maximum pressure per unit area of the filter paper. Unit: kPa
