Analysis of the Filter Paper

There are two main aspects of filter paper analysis: the filter characteristics of filter paper and the physical properties. Mainly carry out the relationship between the physical properties of their filter paper and the performance of the filter, the relationship between the filter characteristics of the filter paper and the performance of the filter. The interaction between the various indicators of the filter paper is related to each other, and several parameters of the filter paper determine the filtration together. Performance.

Technical indicators:
The technical specifications of the filter paper can be mainly divided into two aspects, one is the filter characteristics of the filter paper, and the other is the physical characteristics. Filtration characteristics include gas permeability, maximum pore size, and average pore size. Physical properties include basis weight, thickness, stiffness, burst strength, resin content, and the like.

Quantitative: quality of filter paper per square meter, unit: g / m2.
Refers to the thickness of the filter paper, excluding the corrugation depth. Unit: mm.

Air resistance: the resistance of the filter paper to air flow. The value of the pressure drop obtained by passing 100 cm of filter paper through 85 liters of air in one minute is indicated. The unit is mbar. or water column height.

Corrugation depth: The depth of the groove pressed to enhance the longitudinal stiffness of the filter paper, in mm. In general, its value is 0.2mm.

Air permeability: the amount of air passing through the filter paper per unit time under a certain area and a certain degree of vacuum. The unit is: l/m2•s.

Maximum aperture: The diameter of the largest sphere that can pass through the filter paper. Unit: μm.

Average Aperture: The pore size derived from the “burst” bubbling pressure is called the average pore size. The unit is: μm.

Burst resistance: The maximum pressure that can be applied to the unit area of the filter paper. Unit: Kpa
