Extruder of polyethylene pipe production line
Extruder is a machine that imports to polymeric materials (granules), dynamic and thermal forces, until pass at the end of the device through a mold with pressure, and produce a dough or striped product with a specific cross-sectional shape. Extruders are widely used in polymer industrial with a variety of applications. In simple terms, extruders act like a Meat Grinder, raw material are granular form and to this form comes to extruder, and during mixing, material is heated according to standard, in Extruder output section, materials are in the form of paste and are ready for molding.
In polyethylene pipe production lines, extruder machines are used to primary shaping of polymers for subsequent operations as well as shaping to the final products.
For this reason, practical requirements of each particular application are designed in the extruder, and for this reason, there are wide range of extruder machines.
Pars Ethylene Kish Company uses Battenfeld and Battenfeld Cincinati extruders to produce polyethylene pipes. On the spiral, there are areas for directing of feed (raw material) into the cylinder for compression and preparation of uniform melt and pumping of molten material into the Die Head. Heat energy is supplied to melt material through spiral rotation (tensions from the spiral to the raw material) and thermal elements around the cylinder, and for controlling thermal energy, special fans are used around the elements.
The process of producing polyethylene pipes (Corrugate single-walled pipes and double-walls pipes) is Extrusion method, which raw materials is entered into the extruder as granules, and melt through heat, then molten material moves forward with screw (spiral rod), and After leaving extruder, it enters Die Head. Single-wall polyethylene pipe production line have a main extruder, And some of the lines have Co-extrusion (small extruder).The use of Co-Extrusion is for injection of colored raw materials and the insertion of color markers on polyethylene pipes, The pipeline of Corrugate two- wall pipe consists of two main extruder, which one of them, extrudes material of wavy outer layer and other extruder, extrudes smooth inner layer material, and for shaping, enter to the molds, and it is possible to add a Co-Extrusion on the extruders of the line production of Corrugate two- walls pipes, and installation of this extruder is completely optional, and it is not requirements of the production line equipment. However, it should be noted that presence of marker lines may be in line with requirements of the standards for production of polyethylene pipes.
Difference of extruders
Extruder affects quality of the finished product, And quality and function of the extruder is very important as the main part of the polyethylene pipe production line. Technology used, method of monitoring and control of pipe production process, quality of Screw, Quality of parts for continuous and uninterrupted production of the same quality, Energy efficient consumption, Proper mixing of raw materials, Pressure and material exit rates, as well as amount and how to heating of the raw materials, Exit, pressure and rate of the material should be consistent with other product line equipment; These items, are only most basic differences between extruders.
