挤压说明
DFDA-1638 Natural can be processed on a wide range of commercially available thermoplastic extrusion equipment. This material exhibits an ease of processing that is unique for highly filled non-halogen products now on the market. We suggest beginning with the recommended conditions listed below.Extruder Extruder L/D: 20:1 to 24:1 Screws Suggested: Single flight with metering section, Barrier screws, Maddock screw Screw Delivery End: Shallow rather than deep Compression Ratio: 2:1 to 3:1 Screen Pack/Inch: 20/80/20 mesh Temperature Profile Feed Zone: 300°F-325°F (149°C-162°C) Center Zones: 380°F-400°F (193°C-204°C) Head/Die Zones: 350°F-360°F (175°C-180°C) Conductor Preheat: 250°F (121°C) Draw-Down Ratio (DDR) Core Diameter less than 0.5 in (13 mm) 1:1 to 1.25:1 Core Diameter greater than 0.5 in (13 mm) 2:1 Tooling Semi-pressure tooling improves surface finish. Tube-on tooling: Retract guider-tip slightly into die. Die Single tapered short land die is preferred. Vacuum Though not usually necessary, on occasion may help obtain a tight jacket and offset any low DDR effect. Air-Gap/Cooling Water Short air gap (such as 6 in [150 mm]) and ambient water Pre-Drying Pre-drying at approximately 158°F (70°C) for 4 hours is recommended in commercially available dehumidifying dryers. Do not heat over 195°F (90°C). Colorability UNIGARD RE DFDA-1638 Natural is a colorable compound. Color masterbatch materials designed for use with polyethylene or ethylene copolymer wire and cable products are recommended. Generally speaking, color masterbatch added at the level from 0.5 to 1.0% by weight gives adequate color and disperses well in the extrusion process.
