TPU film

TPU film is a plastic material commonly used by plastics manufacturers, and its products cover the scale of industrial applications and civilian necessities. After nearly a year of efforts, the new product development department successfully announced new TPU materials that can be used for compacting and calendering of film, and has now been approved by the downstream customer's compact rolling process.

Now, TPU is widely used in car production, refrigerator production, transportation, civil engineering, footwear, synthetic leather, fabrics, electromechanical, petrochemical, mining machinery, aviation, medical, agriculture and many other areas, with other plastic materials can not Compared with high strength, good resistance, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance, etc., it has high water resistance, moisture permeability, wind resistance, cold resistance, antibacterial, mildew proof, warmth, UV resistance and energy release. Wait for many common features.

The production process of TPU film mainly adopts blown film method and casting method. However, the TPU film produced by these two methods has low production value, high energy consumption, high cost, and difficulty in forming large-scale production. The research team has been continuously researching for more than a year, and finally developed a new type of TPU data that can satisfy the calendering process on the basis of adhering to the original physical function. The film produced by the calendering process has low physical property loss, excellent quality and beautiful appearance. It is estimated that the annual output value of a single set of four-roll calendering and compacting equipment can reach more than 6,000 tons.

The preparation of TPU film by the compact calendering method can greatly improve the above problems. The working principle of the closed rubber mixing method (mixing method) is that the two rotors in the internal mixer are relatively reversed, and the material from the feeding port is clamped into the roll gap and kneaded and sheared by the rotor. After the roll gap, the sharp edge of the lower top ridge is pided into two parts, and the gap between the front and rear chamber walls and the rotor is returned to the top of the nip.

During the week around the rotor, the material is sheared and conflicted everywhere, causing the temperature of the data to rise sharply, shearing the macromolecules evenly, and adding activity. According to the working principle of the mixing method, the mixing method is applied to the preparation of the TPU downstream product, which can effectively manipulate the appearance of crystal points and accumulated materials in the film, and is particularly suitable for producing TPU film.

The mixing method also has the advantages of large mixing capacity, short time, high production efficiency, convenient operation and reduced labor intensity, and good for mechanical and automation operations. Together, the film is prepared by calendering, which can be used to manipulate the film uniformity. The compact rolling method has been widely used in PVC film production, but as a new environmental protection material to replace PVC, TPU mixing and rolling has not been reported. The most important skill point is to make the new TPU data suitable for the mixing and calendering process on the basis of adhering to the excellent physical function of TPU.
