Event Details

  • Silicone rubber extruder is a basic equipment of the rubber industry and one of the key equipments that affect product quality. 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.

    Basic Information
    The screw extrusion of silicone rubber extruder mixing rubber is one of the older fields of extrusion technology, which can be traced back to the 19th century. Silicone rubber extruders are significantly different from thermoplastic extruders. First, rubber extrusion is carried out at lower temperatures (up to 130 ° C). Secondly, rubber extrusion is often added to rubber strips (particulates are added only in exceptional cases), and they do not undergo phase changes or a large degree of thickening in the screw extruder system. This is not like thermoplastics. Thermoplastics are processed at a temperature of 180 ^ -300 ° C (or higher) in a screw extruder. Low-density solid pellets are often collected in the extruder. During forward motion, the molten well is compacted.
    classification
    Silicone rubber extruders are usually classified by hot and cold feed machines. In a hot-feed extruder, the compounded rubber is heated by the mechanical action of an open mill. These heated rubber strips are cut off and continuously fed to the extruder. In a cold-feed screw extruder, a rubber strip at room temperature is added to the extruder. Rubber extruders are also often classified by whether they are used for exhaust.
