Problems solved by technology

[0003] In the aspect of treating the sewage in the production workshop of decorative materials, it can also be filtered through the graphene membrane. Fast evaporation, but in the actual production process, it is often necessary to stop the machine when replacing or adding PET film, and then pump the air again after the PET film roll is replaced. This method not only needs to stop the machine for processing, but also reduces production. At the same time, workers are often required to pay attention to whether the material is used up, which increases labor costs. At the same time, due to the fluidity of the solution during the production process, the final product has a large deviation in shape, resulting in low quality of the final product.

Abstract

The invention discloses a graphene film for treating sewage in a decoration material production workshop and a processing technology thereof, comprising the following steps: ultrasonically soaking and stirring graphene oxide, filtering impurities, spraying graphene oxide solution onto a PET film, and continuously drying 1. After the graphene oxide and the PET film are peeled off, a graphene oxide film is formed, and the graphene oxide film is carbonized and graphitized to obtain a graphene film. The method is simple in technology and easy to popularize; the present invention automatically continues the PET film through the setting of the discharge structure, thereby effectively increasing the preparation speed of the graphene film and improving work efficiency. The edge of the final product of the graphene film is smoother, which effectively improves the quality of the product.
