Los productos plásticos brindan mucha comodidad a nuestra producción y vida. Este es el lado bueno. Por otro lado, causa una de las mayores fuentes de contaminación en nuestra vida. No se degradará de forma natural, y la máquina peletizadora de plástico lo resuelve bien. Esta contaminación ha hecho realidad el reciclaje de plásticos de desecho.

¿Cómo se renuevan los plásticos de desecho en el? máquina de pellets de plástico? Echemos un vistazo más de cerca

After the plastic is added to the hopper, the hopper falls smoothly onto the screw and is bitten by the screw thread. As the screw rotates, the thread is forced to advance toward the head to form a mechanical conveying process.

When the plastic is running from the feeding port to the pelletizer machine head, the thread depth of the screw is gradually reduced, and due to the resistance of the filter screen, the manifold and the head, high pressure is formed during the plasticizing process, and the material is pressed very much.

La densificación mejora su conducción de calor y ayuda a que el plástico se derrita rápidamente. Al mismo tiempo, la presión que aumenta gradualmente provoca que el gas originalmente presente entre los gránulos se descargue por el orificio de ventilación.

While the pressure is rising, the plastic is heated on the one hand by the outside. On the other hand, during the movement of compression, shearing, and agitation, the plastic itself generates a large amount of heat due to internal friction.

Under the combined action of external force and internal force, the plastic The temperature gradually increases, and its physical state also undergoes a change in the glass state, a high elastic state, and a viscous flow state.

Generally speaking, in the feeding, the glass state is mainly in the middle portion of the compression section where the screw thread is gradually reduced, the material is mainly in a high elastic state, and gradually melts, and the material is in a viscous state at the rear and the squashing section of the compression section.

This is that the plastic has been completely plasticized, and the plasticized plastic is pressed, quantitatively and uniformly continuously extruded from the machine head by screw inference.
