Machine introduction:
Rubber extruder, is a basic equipment in the rubber industry, is one of the key equipment affecting product quality, and plays a very important role in the production process of tires and rubber products. The development of rubber extruders abroad has experienced stages such as plunger extruder, screw type hot feed extruder, ordinary cold feed extruder, main and secondary thread cold feed extruder, cold feed exhaust extruder, pin cold feed extruder, composite extruder and so on.
Main use cold feed type
The design of vacuum extruder screw is presented by cold feed exhaust extruder. The screw used can be divided into ordinary type cold row screw and strong shear type cold row screw according to the flow state of the screw groove in the narrow compression section of the rubber material. The screw of the cold feed exhaust extruder is divided into feeding section, compression section, throttling section, exhaust section and extrusion section. The throttling section adopts shallow groove equal distance and equal depth thread, which can make the rubber material obtain higher shear and stable conveying process, and also improve the exhaust effect. In a cold feed screw extruder, a room temperature adhesive strip is added to the extruder. Rubber extruders are also often classified by whether they are used for exhaust
recombination
In the rubber industry production, the composite extruder is mainly used for the extrusion of composite tire tread, automotive sealing rubber strip, color force tire tread, rubber hose composite and plastic composite extrusion, as well as multilayer co-extrusion of rubber sheets. The composite extrusion production process is an advanced technology in the rubber industry production, which can be based on the different performance requirements of the product, using different formulations and properties of the rubber material, through the composite extrusion equipment to produce products that can save materials and meet a variety of performance needs.
Epdm rubber is widely used, mainly used in housing construction, wire and cable, automobile industry and other fields. In terms of housing construction, it is mainly used for single-layer waterproof coil on the roof. In terms of wire and cable, it is mainly used for input lines of civil and commercial buildings, construction wires, mining cables, nuclear power plant wires, automobile ignition lines, control and signal cables, etc. In the automotive industry, it is mainly used for automobile, truck and bus tires and non-tire components, including automobile water tank and heating hoses, seals, rubber belts, body and chassis components, rain strips, bottom plates and ring pipes.
