Huihuang Centrifuge Factory provides practical new plastic lining technology for chemical equipment

The lining plastic (PE/PP powder) process for large chemical containers. It has the following process flow: a. Installing metal skeleton; B Shot blasting and cleaning the inner surface of the container and the surface of the metal skeleton to make them clean; c. The inner surface of the container and the surface of the metal skeleton are treated to make the inner surface of the container and the surface of the metal skeleton form an interface facial mask; d. Put the container into the heating furnace for heating; e. Apply plastic hot compress to the inner surface of the heated container; f. For the solidification treatment of the container after hot pressing plastic: g. Remove the container from the furnace and cool it with air to form the product. The present invention addresses the practical technical difficulties involved in the lining of large chemical containers. By designing the structure of the lining layer, selecting suitable materials and lining molding process parameters, the technical difficulties of lining are solved, enabling the lining of large chemical containers to be realized.

A large chemical plastic lined container is made of a steel shell, the inner surface of the container shell is provided with a plastic layer, the inner surface of the plastic layer is provided with a metal skeleton, the metal skeleton is welded on the inner surface of the steel shell, and the inner surface of the container shell and the metal skeleton are provided with a boundary facial mask. The advantages of this utility model are reasonable structure, good corrosion resistance, and wide application.
