Application of reciprocating single screw mixing extruder plastic plate production line
Reciprocating single screw mixing extruder is a new type of mixing and processing equipment for plastics. It is widely used in the production of filling, blending, reinforcing, crosslinking, grafting, color masterbatch, functional masterbatch, flame retardant masterbatch, conductive material, degradation masterbatch, etc. When preparing high concentration color masterbatch, the pigment and additives are directly measured, and the color masterbatch with good dispersing effect can be obtained without pretreatment. The amount of pigment is reduced, the production cost is reduced, and the production environment is improved. The production of various glass fiber reinforced products, glass fiber add up to 50%. It is especially suitable for the production of various cable sheathing materials, insulating materials, cross-linking materials, semiconductor materials, shielding materials, conductive materials, hard and soft PVC products and other heat sensitive materials, as well as the production of thermoplastic elastomer and hot melt adhesive. The content of carbon black in black masterbatch produced by reciprocating single screw extruder is as high as 50%, and there is no special requirement for raw materials and no pretreatment. For example, when the black masterbatch made of carbon black N330 is applied to the blown film, there is no need to add coupling agent, the amount of polyethylene wax is reduced, and the effect of uniform distribution can still be achieved. When the short glass fiber reinforced polyolefin is prepared, the glass fiber dosage can reach 50%, and the mixing effect is better than that of twin-screw (because the shear strength of twin-screw is larger and the average effective length of glass fiber is shorter).plastic plate production line handern.comReciprocating single screw mixing extruder is especially suitable for all kinds of filling modification. Because it is equipped with two forced feeding hoppers, a large amount of filler can be added in two parts, and premix is not required. Moreover, it can avoid the torque increase and filling difficulty caused by adding a large number of fillers together with the base material, so it can produce some products with large filling amount and difficult filling. The special screw structure and movement form can disperse it well. For example, when PE is filled with light calcium carbonate, the filling amount can reach 200%. When using reciprocating single screw extruder to produce inorganic flame retardant materials, the filling amount of magnesium hydroxide and aluminum hydroxide can reach 60% ~ 70%, and the flame retardant effect is excellent.
With the help of the pin of the reciprocating single screw extruder, the real temperature of the melt can be measured, and the accurate temperature control can be achieved, which is also impossible for the twin screw extruder, which is extremely beneficial to the preparation of thermosetting composites. Therefore, the reciprocating single screw extruder creates a new process for the preparation of thermosetting composites, and accelerates the research, development and application of thermosetting resin composites.plastic plate production line handern.com
Reciprocating single screw extruder is also a kind of high-efficiency and energy-saving plastic extrusion mixing equipment. Compared with other extruders with the same output, it can save about 1 / 4 of energy. It is more and more widely used in the field of plastic modification and has made contributions to the development of plastic industry.plastic plate production line handern.com
