Rubber extruder

Read: 3802 Release time: 2013/11/30

China is a country with a large population, so it is also a country with large energy consumption and a country with a large demand for various products. So how to meet this big problem? This requires the help of some machines. The development of our economy is also very Rapidly, it has driven the rapid development of science and technology in our country, and also promoted the development of some emerging industries.
The rubber extruder is a basic equipment of the rubber industry and one of the key equipments that affect the quality of the product. It plays a very important role in the production of tires and rubber products. The development of foreign rubber extruders has experienced plunger-type extruder, screw-type hot-feed extruder, ordinary cold-feed extruder, main and auxiliary thread cold-feed extruder, cold-feed exhaust extrusion Machine, pin cold feed extruder, compound extruder and other stages.
Rubber extruder is divided into: plunger type, screw type, ordinary type, cold feeding type, pin type, compound type.
With the emergence and wide application of cold feed extruder, the application range of hot feed extruder is gradually shrinking. From hot feed to cold feed, cold feed pin extruders have become the mainstream of development. In the past ten years, it has been widely used in the production of rubber industry in China, and its use has been expanding. The pin-type cold feed extruder introduced earlier in China is mainly used for the production of rubber core and rubber in the production of radial tire tread rubber and hose production. However, in China's rubber industry production enterprises, hot-feed extruder still accounts for a large proportion. According to incomplete statistics, the hot-feed extrusion process using open mills to supply rubber accounts for about 70% in China. Many old rubber manufacturers in China use extrusion equipment, processes and equipment from the 1950s. behind. Some companies believe that the old extrusion equipment has certain advantages, such as good dispersibility, good operability, and skilled operators. However, the advantages of pin-type cold-feed extruder are greater than hot-feed extrusion. Out of the plane. Pin-type cold-feeding extruder represents the localization of advanced rubber equipment, which is conducive to the promotion of new equipment and technologies, improving the level of enterprise equipment, and promoting the development of production, especially due to the rapid development of radial tire production and pin-type cold feeding in China. The advantages of the extruder make the promotion and application of the pin-type cold feeding extruder have greater advantages. It has become a replacement product of the hot-feed extruder and the ordinary cold-feed extruder. It is a pin-type cold feed. The extruder provides broad development and application prospects. The development direction of the extruder has great development potential. It can be seen that there is still much room for the technological transformation of the extrusion process in China's rubber production enterprises to further promote the use of pin-type cold-feed extruder.
Future development trends: 1. Multi-screw 2. Multi-flow channel 3. Multi-composite 4. New drive 5. Control system 6. Precise technology
Since the advent of pin-type cold-feed extrusion technology, extruder manufacturers at home and abroad have continued to explore new extrusion technologies. But so far, whether it is MC TD and gear pump extrusion technology, or other extrusion technologies, although they all have certain advantages, they are not dominant in terms of increasing production, reducing glue temperature and reducing energy consumption. It is complicated, difficult to maintain and difficult to be accepted by users, so it does not have scale advantage in actual use. In the field of future extrusion technology, pin-type cold feed extrusion technology will still lead the pack. At the same time, China's compound extrusion technology is becoming more and more perfect, which can fully meet the various needs of different users. China is a major producer of rubber machinery in the world. It is an area where the development of rubber machinery in the world is fast. Then the wear and tear of the machine requires corresponding parts. The development of corresponding parts is also very optimistic.
