Introduction of a rubber powder processing technology (translation)

Type. Head for the planetary gear extruder can not establish a sufficient back pressure, it must be a single screw extruder with the planetary gear extruder used in tandem. Mixing can be formed into the final slope of granular, plastic molding strip or convert the shape, or phase end with the calendar pressed into film sets, the production line may also increase the strainer device. This process has the following advantages: ① to improve the uniformity of the compound, ② to improve physical performance, ⑧ reduce overall energy consumption | ④ reducing heat history (time / temperature relationship). Mixing principle of planetary gear used in this process as a continuous mixing extruder and plastic mixing device. Planetary gear extruders in the plastics industry has been widely used in PVC and other polymers of the continuous mixing and thermal plastic mixing. According to the needs of accuracy, measured by volume or weight feeder feeders will go through pre-determined mixture of powdered rubber material mixed with a continuous feed planetary gear sets extruder feed screw the powder mixture into the planetary gear rubber adequate mixing zone and plastic mixing. Plastic mixing refining zone by a drive shaft, a fixed extruder barrel and symmetrically distributed in the extruder barrel and the drive shaft axis between the number of root form planets. Turn the drive shaft rotational axis of the planet, in order to avoid axial movement of each axis, in the barrel of a 1:1 end of the installation of a thrust ring. Spindle and the extruder barrel by the force of circulating water heating and cooling. Planetary gear extruder mixing plastic mixing effects than the two roll mills confidential much better. Compound in the main shaft, the extruder barrel and the gap between the planetary axes to get a strong shear. Compound under high shear constantly being pressed into thin slices, and then in the machine the gap between the cylinder axis of the planet to get loose. The extruder barrel and spindle formation process of the canine tooth surface, and violent movements of these surfaces, so heat transfer is very good,[link widoczny dla zalogowanych], which can effectively prevent overheating of the compound. Screw shaft speed and the number of planets determines the shear energy input, while in terms of a particular compound, they can be transferred to the best value. 5. Spiral tooth surface can guarantee (the compound) without pressure transmission, and to make the planet also has a good self-cleaning ability. Discharge from the planetary gear extruder of plastic material with no pressure was taken with the planetary gear extruder linked to a hot feed extruder, after processing through the extruder to form pellets,[link widoczny dla zalogowanych], film, type of plastic or the supply of rolling and so on. Zhang, according to the performance of rubber technology and test equipment, the results shown in Figure 3 is using a planetary gear extruder WE140 obtained. Compound with several different real ride, productivity and energy consumption of rubber than the planetary temperature as a function of screw speed. WEt4o planetary gear extruder and matching GEtBo hot feed extruder than the total energy consumption of about o. 16kW ・ h / kg, which mixer / two combination roll machine than the energy consumption of 0.26kW ・ h / kg comparison, there are clear shortages of the advantage. Yao Jin dance production capacity of silver carp Naofei {1o2. ∞ 40 ∞ rod speed: r ia Aumann pumping Gu plastic pad like the whole focus of one (on the next page 3l) 4 temperature steam cycle electric hybrid heating system renovation of the old machines and new machines have great significance supporting the current domestic energy production few high-precision temperature control system, there is a different shortcomings, many factories still rely on imports, to spend a lot of foreign exchange. Temperature is basically imported electric heating, this extremely energy-wasting electric tiger is very uneconomical. Development of Qingdao Institute of Chemical Vapor-electric hybrid heating temperature control system, which has energy-saving, simple structure, heating, high precision,[link widoczny dla zalogowanych], smooth, attractive appearance, small footprint, speed of production capacity Lo Park: r / mia productivity based on the current lap 4 planetary gear extruder of existing specifications, production efficiency can be achieved 50001b / h. Conclusion This article describes the basic settings of this device is for processing powder or granular rubber was developed with good results, but because of the reasons mentioned above, this technology in the rubber industry has rarely been accepted. As more freely flowing powder or granular appearance of rubber raw materials, this technology is expected to be born and grow up to be more mushroom. The elastic body (processing) to achieve continuous mixing stick, is still raw material producers, equipment manufacturers and rubber processors are an important goal pursued. And so on,[link widoczny dla zalogowanych], and steam heating and electric hybrid control plane also has a new nature, its large rubber device of supporting the temperature control system and transformation of the old machine does have great significance.
