Original Title: Application of GNOSS Automatic Melt Filter in Film Extrusion Process Due to the increasing market demand for thin films, the production process of thin films is becoming more and more complex in order to ensure the provision of high-quality thin film products. In addition to the use of special extruders, dies and winding machines, melt filters are also crucial in the configuration of production equipment. A fully automatic melt filter is used to filter out contaminants such as gel particles and minimize the appearance of "black spots" or "fish eyes". In addition, the use of fully automatic continuous melt filters can avoid downtime and reduce waste of raw materials. Product in kind: Gnoss Automatic Rotary Melt Filter With the patented rotary filtration technology, the gneuß fully automatic melt filter is the highest standard of melt filters on the market today, with impeccable product quality,nutsche filter dryer, cost-effectiveness, ease of operation and maintenance. The automatic melt filter consists of three main parts-inlet block, outlet block and filter disc. The filter screen is distributed in the annular part of the filter disc. When the melt flows through the filter screen,rotary vacuum evaporator, the pollutant particles are intercepted and the pressure difference is slightly increased. By sensing the pressure change, the control system automatically rotates the filter disc to make it rise by 1-2 degrees. The dirty screen leaves the melt channel while the clean screen is fed into the melt channel with the effective filter area unchanged. As a result of this mode of operation, the filtration system runs continuously without interruption and the pressure remains constant. In the standard case, the maximum variation of the filter differential pressure is only 2 bar. Melt Filter Operation Schematic The following data is from a customer of gneuß. This customer produces PP stretch film. The thickness at the exit was 335 μm, after which the film was stretchows the maximum relative deviation from the set value of 335 μm. The base time for the melt filter was set to 180 seconds. Select this time setting so that you can see if the operating cycle of the filtration system has an effect on the membrane thickness. In theory, thin film distillation ,winterization filtration, there should be a change every 180 seconds or every 10 measurement intervals. Looking at mal deviation of about +/-0.6% for other factors in the extrusion line, these figures are only minimally improved in the filtration system.
