About Filter Paper Selection And Types

There are three factors needing to consider in filter paper selection:

1.Effective area: the larger the effective area, the larger the dust holding capacity, the smaller the resistance, and the longer service life. And of course, the cost is correspondingly increased.

2.Fiber diameter: The finer the fiber diameter, the better the interception effect and the higher filtration efficiency.

3.The content of the binder in the filter material: The high content of the binder means high tensile strength of the paper and high filtration efficiency. The phenomenon of hair loss rare appears, with small dust, but the resistance increases accordingly.

Types of filter paper

There are two types of filter paper: qualitative filter paper and quantitative filter paper. The difference is the amount of ash after ashing. The qualitative filter paper ash is less than 0.15%. The quantitative filter paper ash is less than 0.01%.

The filter paper whether qualitative or quantitative can be divided into three types: fast speed, medium speed, and slow speed. The difference lies in the nature of the precipitation property of the separated material. Fast filter paper is suitable for colloidal precipitation and slow filter paper for crystal precipitation.
