Rubber Recycling Equipment, Waste Tire Devulcanizaiton Machine

Green &intelligent Normal temperature &pressure Rubber De-cross linking Process

Technique characteristics

1. The activation effect of the rubber powder completely reaches and exceeds the level of the dynamic desulfurization tank, and becomes an environmentally friendly, energy-saving, safe, efficient, clean, intelligent, and innovative one that can completely replace the "dynamic desulfurization tank" to produce reclaimed rubber. It's an innovative production process that subverts the traditional activation of recycled rubber.
2. The whole process uses program-controlled fully automatic computer control or can use the Internet to realize equipment remote control, and can become era equipment that promotes the production of recycled rubber from waste rubber, such as waste tires, that is completely operated by robots.

Technique principle

By the integrated control program, the prefabricated rubber powder is automatically and mechanically sheared, and the physical phenomenon of thermal energy generated by the rubber powder-rubber powder, and rubber powder-equipment mechanical shearing during the operation of the shearing and grinding process is used to obtain the physically activated function of the rubber powder.

Activation process

The normal temperature rubber powder is conveyed into the closed activation equipment through a screw, and through mechanical shearing and friction, the rubber powder reaches the condition that meets the requirements of the set activation temperature during the controllable shearing and grinding process and generates heat for activation. After activation, The rubber powder enters the cooling device for rapid stirring and cooling through temporary parking, and the activated rubber powder is mixed and extruded through the special mixing and kneading equipment, and the activated rubber powder reaching normal temperature is output by the cooling transmission and conveying equipment. The output activated rubber powder has become an activated rubber material, and the performance and appearance of the activated rubber material already possess or reach the effect of 5-6 refining times in a traditional conventional refining machine.

Features

During the entire activation process, the special shearing and grinding process is used to complete the activation. The special shearing and grinding process solves the uneven thickness and inconsistent activation of the rubber powder during the activation process so that the activated rubber powder is completely transformed from elastomer to plasticity. The physical effect plays a key role in the improvement and stabilization of various indicators of recycled rubber products. According to the recycled rubber national standard, Mooney is stable and rebound small; Compared with the recycled rubber produced from the same raw material with any other activation process, the strength is higher than 0.5 to 1.0 Mpa, and the elongation is higher than 20% to 30%. The activation effect is thorough, the Mooney is controllable, the elongation and strength are stable, and the physical properties are high or higher than that of recycled rubber produced by other activation processes.

The activated rubber is in the activated kneading form instead of the powder form. The reclaimed rubber produced by this process has a black and shiny appearance, and the processed rubber has good fluidity and is suitable for rubber molding. Widely used with extruded products. It is especially suitable for the late-stage mixed-rubber that needs to be added with recycled rubber to directly enter the internal mixer or directly enter the refining machine to be processed into reclaimed rubber, it can also directly enter the rubber extruder for processing. It is sheet-shaped recycled rubber with a wide processing range.

Energy saving

Except for the operation of motor supporting to the equipment, the rubber powder activation completely relies on the heat energy generated by the equipment itself. This completely changes and bids farewell to the traditional desulfurization mode that requires internal heating or electric heating for the desulfurization. Compared with the traditional production process, the energy saving is 40%, which laid the foundation for energy saving and emission reduction.

Environmental protection

Except for the small amount cooling circulating water for cooling the heated rubber powder in the activation process, there is no water is added during the production process, so no wastewater or waste gas is produced, which effectively avoids water pollution.

Safety

The whole operation process is at atmospheric pressure, with no pressure and no safety hazards.

Intelligent

The whole process adopts program-controlled fully automatic, computer display control operation.

Clean

There is no solid waste or liquid pollutants being discharged. The whole activation process is completely in a sealed working environment and is intelligently controlled by a program-controlled computer.
