▎ 摘　　要

NOVELTY - Production of full heat exchange graphene paper film comprises raw paper making, preparing a surface sizing liquid and applying the surface sizing liquid, preparing plant fiber slurry, making base paper on a cylinder or fourdrinier paper machine, the beating degree of plant fiber pulp is 30-70 SR, and the speed of papermaking is 50-100 m/minute. USE - The method is useful for the production of full heat exchange graphene paper film. ADVANTAGE - The method: reaches 70-78% sensible heat efficiency of the fresh air system by using this full heat exchanger core.
