Fantastic News: S&L's Timely and Successful Delivery of Coating Mixers for TPU Granules

Unveiling TPU

TPU, which stands for thermoplastic polyurethane elastomeric rubber, is a remarkable material with diverse characteristics. It is primarily categorized into polyester type and polyether type. TPU boasts an impressively wide hardness range, spanning from 60HA to 85HD. It also exhibits excellent abrasion resistance, oil resistance, transparency, and outstanding elasticity. The halogen-free flame-retardant variant of TPU has been increasingly substituting soft PVC in numerous fields, as it meets the growing environmental protection requirements. TPU is renowned for its strong high tension and high tensile force, making it a well-established and environmentally friendly material. It has even obtained relevant certifications as an international green environmental protection material, which is why it has found its way into the realm of organic photoelectric materials and is attracting more and more attention. Presently, TPU is widely utilized across various industries, including shoe materials, garments, inflatable toys, water and underwater sports equipment, medical equipment, fitness equipment, car seat materials, umbrellas, suitcases, and leather bags, among others.

Understanding the Ribbon Mixer

A ribbon blender, also known as a ribbon mixer, is composed of a U-shaped shell, double ribbons, and drive units. The outer ribbons function to transfer raw materials from the two ends towards the center, while the inner ribbons move the materials in the opposite direction, creating a counter-current movement. This unique design makes such mixing and coating equipment highly popular and widely used in TPU applications nowadays.

The Secret Behind S&L's Ribbon Mixer for Perfect Coating during Mixing

Motor Power Selection: Given the elastic properties of TPU, carefully selecting the appropriate motor power is of utmost importance. S&L's ribbon mixers are designed with this in mind to ensure optimal performance.

Agitator Rotation Speed: The rotation speed of the agitator must be carefully calibrated and kept within a reasonable range. This is crucial to prevent the generation of static electricity, which could potentially affect the quality of the mixing and coating process.

Seamless Welding: The welding between the mixer vessel and the end plates of S&L's ribbon mixers is carried out with precision to ensure a seamless, rounded, and smooth finish. This eliminates any potential dead areas that could lead to product blockages during the mixing process.

Gap Consideration: Due to the specific shape of TPU granules, special attention is paid to the gap between the agitator and the mixer body. S&L ensures that there is a uniform clearance in the lower section to prevent any deformation of the TPU granules caused by compression.
