High shear extruder of the most common questions

High shear extruder The most common problem is not to take vent material, but by the feeding section and the compression section shear heat is too high, causing the material in the vent appears linked material "sticky wall" symptoms. Boot time, the parison yellow line appears difficult to produce normal. Therefore, the two should make reducing the set temperature, reducing the external supply of heat or adjust the formula, increase the amount of lubricant or decrease processing aids. jasper engineered flooring reviews

If the effect is not significant or changes to the formulation of lubricants and processing aids cause mass changes profiles, as well as performance while using different shear extruder production, the same blending, storage material, conveying systems, it is impossible for the high shear extrusion Another ingredient of the machine alone, only lower extrusion speed, interval running at lower extrusion efficiency. It can also remind the business at the time of adding or updating an extruder, preferably an extruder screw design and purchase identical or similar performance model. In the extrusion process, the material from the molten glass into the process, improve the balance of heat in addition to plastics materials and the required heat supply, so that the material to complete the ideal of plastics, the melt pressure is a very important control targets. As the material by die resistance during extrusion screw squeezing ratio of each segment, is not itself in the presence of atmospheric pressure. how to install wood deck tiles over grass

Different die, screw each segment compression ratio is substantially constant, immutable. The compression ratio of each stage of the screw of the screw material is only the pressure distribution and adjustment of each segment, it is impossible to increase or decrease the total pressure in the melt extrusion process. The total pressure adjustment mainly rely on extrusion speed, feed rate and W extrusion method than other processes. Adjust the extrusion speed, feed and extrusion speed ratio is not only an important measure to adjust the extrusion temperature, but also the main measure melt pressure adjustment to adjust the extrusion efficiency. Under the same premise extrusion speed, increase or decrease the feed rate, the feed section of the screw material changes in the volume of the exhaust section material volume remains the same, so the feed section, the compression section with the compression ratio changes, the melt pressure over The increase or decrease; at the feed rate constant premise, increase or decrease the extrusion rate, the volume of the feed section of the screw material has changed. Exhaust section material volume remains the same, so the feed section, the compression section with the compression ratio changes, the resulting melt pressure increase or decrease; feed speed synchronized with the extrusion speed increase or decrease, due to the volume of the feed section of the screw material not change, only the change in pressure due to the melting rate of increase or decrease, due to.
