Introduction of filter paper technical indicators
The technical specifications of the filter paper can be mainly divided into two aspects, filtration characteristics, and physical characteristics. Filtration characteristics include air permeability, maximum pore size, and average pore size. Physical characteristics include quantitation, thickness, stiffness, burst strength, resin content, and the like.

Filtration characteristics
1. Air permeability refers to the amount of air passing through the filter paper under a certain area and a certain degree of vacuum, unit: l/m2·s.
2. Maximum pore size is the diameter of the largest sphere that can pass through the filter paper, unit: μm
3. The average pore size is the pore size derived from the “burst” bubbling pressure, unit: μm.

Physical characteristics
1. Quantitation refers to the quantity of filter paper per square meter, unit: g / m2.
2. Thickness refers to the thickness of the filter paper, excluding the corrugation depth, unit: mm.
3. Stiffness is the ability of the filter paper to deform, unit: mg.
4. Burst strength refers to the maximum pressure that can be applied to the unit area of the filter paper, unit: Kpa.
5. Resin content refers to the percentage of resin in the weight of the filter paper.

Relationship between physical characteristics of filter paper and filter performance
1. Quantitation
Quantitation in the filter is mainly reflected in the weight and price of the filter. Under a certain filtration area, the larger the amount, the heavier the filter paper and the heavier the filter. Since the cost of filter paper accounts for a large proportion of the cost of the filter, the cost is higher.

2. Thickness
For corrugated cylindrical filters, the thickness of the filter paper limits the maximum filtration area of the filter.
