Description

Technical Field

[0001] The present invention relates to the technical field of the production of powdery film release agents, and specifically relates to a production method and production equipment for powdery film release agents. Background Art

[0002] Powdery film release agents are mainly used to prevent unvulcanized rubber compounds from sticking to each other, facilitating stacking and storage. Powdery film release agents can effectively prevent the adhesion between films, keeping the films separated during stacking and storage. Some products are dust-free, do not pollute the environment, and are friendly to the workshop environment. Some products have a stable suspension after being dissolved in water, do not produce foam, and can still return to a uniform dispersion after long-term standing, without affecting the use performance. Powdery film release agents are particularly suitable for the production process of rubber products such as tire conveyor belts or rubber and plastic products. Usually, the powdery film release agent needs to be dissolved in water to prepare an aqueous solution with a certain concentration. The specific preparation method may vary depending on the product, but generally, it needs to be stirred until evenly dispersed. The prepared release agent solution is evenly applied or impregnated on the surface of the unvulcanized film to form a separation layer. The release agent will form a pale white film on the film surface, which has excellent separation effect after drying;

[0003] With the continuous changes in people's lives, the use of powdery film release agents has become more and more common, which makes the production of powdery film release agents also become more and more common. However, the traditional production method results in poor stability of the produced products, which makes their use have great limitations. Therefore, a new production method is proposed now to solve this technical problem. Summary of the Invention

[0041] Preferably, according to the requirements of the product form, the mixed powder is processed into granules or flakes through a granulator or a tablet press, which is divided into two cases: processing into granules by a granulator and processing into flakes by a tablet press. The steps of processing into granules by a granulator are: selecting a suitable granulator, adjusting granulation parameters, the granulation process, screening and drying.
