Comparison of the advantages and disadvantages of Protective film coater filtration products

1. Filter bag/filter cloth of Protective film coater

The advantage is that it is cheap, but the disadvantage is that it is not good performance. Due to the process characteristics of the material itself, it is composed of a single-layer filter cloth weaving, when encountering viscosity and pressure, the pores are easily deformed and squeezed, and it is impossible to intercept the fine particles and soft rubber particles in the glue; Moreover, the voids are unstable, resulting in unstable batch filtration.

2. Ordinary filter element of Protective film coater

The advantage is that this type of filter element is less expensive and will be improved over the filter bag or screen. However, there are many disadvantages of the protective film coater: first, the filtration results are general, which may not meet the harsh requirements of high-end protective films; Second, the gel in the glue cannot be removed; Third, the Protective film coater is simple to make, and does not do stability checks; Fourth, there are fiber shedding and other phenomena, polluting the glue.
