How To Choose The Filter Fabric Of Industrial Paper Belt Filter?

How to choose the filter paper ( Filter Cloth ) of the industrial paper belt filter? At present, there are many Filter Fabric on the market. The Filter Cloth Fabric used for industrial liquid filtration is mainly made of PET and PP materials. And if different materials or different processing conditions are used, even if the unit weight of the Filter Cloth Material is the same, the filtration accuracy will be very different. So how should the user choose the Filter Fabric Non Woven? Consider the following aspects:

1. It is necessary to confirm the working conditions including the solid - liquid composition of the filtration object, the filtration pressure difference, the temperature of the filtration liquid, the filtration volume per unit time, the principle of the use of the filtration equipment, and the mechanical strength requirements for the filter cloth.
2. It is necessary to determine what kind of filter material is used in the current filter equipment, such as: whether there is a uniform rolling point, how much thickness, how much unit weight, and what problems are there during use ( whether there is too much foam, whether it is easy to tear, whether the flow rate Insufficient, whether the filtering precision is insufficient ) and so on. If there is no way to describe it, you can provide samples to the technician for analysis, or the technician can go to the site to investigate.
3. Determination of filtration accuracy: Filtration accuracy is a relatively accurate concept, but the pore size distribution of filter paper is a relatively random distribution. In order to determine the accuracy, it is usually measured by the relevant pore size test provided by the filter cloth supplier. Then determine it according to its own operating conditions. It is easy to confuse the filter precision with the unit weight of the Non Woven Filter Fabric itself. Under the same process conditions and the same material, the unit weight is positively correlated with the filtration accuracy. However, it is not an absolute single related relationship. That is to say, if the process conditions change, even the same unit area, the performance result is different filtration precision. Therefore, it often happens that the 90 - gram product of a certain company is replaced by the 100 - gram product of another company, and it is also found that the filtration accuracy cannot reach the original 90 - gram effect.
