Description

TECHNICAL FIELD

[0001] The present application relates to the field of decorative film preparation, in particular to a concentration device for the preparation of high-strength PVC decorative film. BACKGROUND

[0002] PVC is mainly composed of polyvinyl chloride, which is slightly yellow and translucent with luster. Its transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the amount of additives used, it can be classified as soft or hard polyvinyl chloride. Soft products are flexible and have a sticky feel, while hard products have a higher hardness than low-density polyethylene but lower than polypropylene. They may exhibit whitening at flex points. Common products include boards, pipes, shoe soles, toys, doors and windows, wire sheaths, stationery, etc.

[0003] Currently, during the preparation of decorative film, the raw materials are usually heated at high temperature, which not only facilitates the mixing of various raw materials together, but also removes the moisture in the raw materials for concentration. During the concentration process, air containing moisture is discharged from the equipment, which can cause the surrounding air to become humid. Then, the air entering the equipment has a low temperature, which can cause the temperature inside the equipment to decrease, easily causing a large fluctuation in the temperature difference of the equipment, affecting the mixing of the raw materials. Since the raw materials are relatively thick, if a valve is used to control the opening and closing of the discharge port, some of the raw materials will adhere to the valve plate of the valve, making it difficult to clean and causing blockage, which can easily cause the valve to be completely closed.
