What do you know about elastomer extruder?

The working principle of the elastomer extruder is very simple, and the operation is also very simple. But need to pay attention to safety, elastomer extruder can be divided into many categories, can be divided into plunger type, can be divided into screw type and ordinary type. The working principles of different elastomer extruders are different, and it is necessary to distinguish them.

What is the internal relationship between the performance and process characteristics of the material itself and the elastomer extruder?

a. Plastic modification is ever-changing: rubber-plastic blending, plastic alloy, filling modification, toughening modification, glass fiber reinforcement, reactive extrusion, etc.

b. According to the material properties and process characteristics, a reasonable elastomer extruder screw element combination and parameter setting are designed.

What are the characteristics of ordinary elastomer extruder?

From the perspective of equipment structure, the ordinary elastomer extruder has a long body, multiple functions, and low feed temperature, so its power is much larger than that of a hot feed extruder, which is about 2-4 times. The appearance of the common type elastomer extruder simplifies the production process, and the fed rubber material no longer needs to be heated. The rubber material is fed into the extruder at room temperature, and various shapes of rubber embryos can be obtained. The ordinary type elastomer extruder can completely replace the hot feed extruder, and can save the rubber hot refining process, simplify the production process, and enable the machine head to establish a higher pressure, which has a certain effect on improving the quality of extruded products. Therefore, It has been widely used in the production of some products.

What is the difference between the two elastomer extruders?

From the perspective of equipment structure, cold-feed elastomer extruder generally has a longer body compared with hot-feed elastomer extruder, the length-diameter ratio (L/D) is 8-20, and the thread groove is shallower. Due to the long body, multiple functions and low feed temperature, its power is much larger than that of the hot feed extruder, which is about 2-4 times that of the hot feed elastomer extruder of the same specification. For example, the power of the cold-feed elastomer extruder with a diameter of 250 ram produced by the German Berstorff Company is 500kw, while the hot-feed extruder of the same specification is only 105kw, but the production capacity is lower than that of the hot-feed extruder. The emergence of the cold-feed elastomer extruder simplifies the production process, and the fed rubber no longer needs to be heated. The rubber is fed into the extruder at room temperature, and various shapes of rubber embryos can be obtained. It can completely replace the hot feed extruder, and can save the rubber material hot refining process, simplify the production process, and enable the machine head to establish a higher pressure, which has a certain effect on improving the quality of extruded products, so in some It has been widely used in the production of products.
