working principle

This equipment belongs to the airflow assisted melt differential centrifugal spinning device. The center of the centrifugal differential disc adopts a multi circle smooth concentric groove structure, and the concentric grooves are connected to each other, so that the melt can evenly flow and distribute in the groove, preventing the occurrence of uneven melt jet caused by eccentricity.

The edge of the centrifugal differential disc adopts a radial conical comb shaped structure. The melt enters the conical comb shaped structure under the action of centrifugal force and airflow after being homogenized by the groove in the center of the disc. Hundreds of circular uniform "comb teeth" can refine the melt through differentiation, and the conical design is conducive to increasing the adhesion of the melt to the surface of the centrifugal differential disc. The higher the conical inclination angle, the greater the adhesion. After experimental optimization, the optimal value of the conical inclination angle is 10 °. This conical inclination angle can prevent the retention of the melt caused by excessive adhesion. Under the "pulling" effect between centrifugal force, airflow and adhesion, the melt further thins on the conical surface, achieving secondary refinement of the melt jet. The end of the edge of the centrifugal differential disc is equipped with a retaining ring structure, and a large number of micropores are formed between the retaining ring and the conical comb shaped structure, It can prevent the occurrence of uneven fiber quality caused by splashing of the melt during the spinning process.

This equipment is suitable for centrifugal spinning of various polymers. The spinning polymers can be thermoplastic polymers such as polypropylene, polyethylene, and polylactic acid. The spinning raw materials can be polymer pellets, powders, or melts. The receiving device can take various forms such as receiving mesh rings, receiving circular curtain fabrics, and the receiving device can adopt suction airOr use static electricity to pull and adhere fibers.
