Filters and screens What's the difference?
Time:2016-07-05

It is the use of silk screens, wire or synthetic fiber raw materials such as weaving, has a uniform and stable surface holes, having a screening and filtration of industrial fabrics. Called on the mesh sieve mesh habits. Screen specifications often holes (mesh) per unit length, said width of each hole is also useful to representation. Chinese national standard to represent the number of holes per centimeter, such as 20 holes / cm.

Pre-filter suggests that it is referred to as the filter of the extruder feed simply by the different networks supported sieve mesh wire mesh group, whose role is to filter the melt flow and increased flow resistance, in order to filter out impurities and improve mechanical mixing or plasticizing effect. If the screen filter to the large debris (such as paper), it will suddenly fail completely, which would make the extruder pressure filter quickly reaches a peak. Therefore, in order to prevent this from happening, it must have a security system such as rupture disc, pressure gauge and a safety pin or an alarm connected to and the like.

For single exhaust, two extruders, if the back pressure of the filter becomes large, then the output of the second stage will be reduced, but the first stage output will not be affected. When the back pressure increased to about 2500 lb / in2 (1lb = 0.4536Kg, 1in = 25.4mm), the molten material from the first stage began slowly leaking into the vent. To avoid such phenomena, must be at a low pressure to replace the filter. In addition, the filter device behind the gear pump also inhibit the molten material leaking into the vent effect.
