    The project appraisal meeting of the "New Process for Clean Production of Green Cellulose Membrane" jointly developed by the Institute of Chemistry of the Chinese Academy of Sciences and Weifang Henglian Cellophane Co., Ltd. was held in Beijing. After detailed inquiries and heated discussions, the expert committee agreed that the new process of green cellulose membrane clean production meets the development requirements of green chemistry and clean production, and has significant energy saving and environmental protection characteristics. The craft is an international initiative, and its comprehensive technical level is international *. The experts also put forward constructive opinions on the intellectual property protection of the new process and the acceleration of industrialization on the basis of further improvement and optimization.
 
    Cellulose is a natural polymer with abundant reserves in nature, and the amount of cellulose produced in nature each year exceeds 100 billion tons. As a kind of natural and non-edible biomass resources, cellulose is considered to be the main raw material for human future chemistry and chemical industry. Cellulose has excellent fiber-forming properties, film-forming properties, and excellent mechanical properties. The film prepared by it is widely used in daily necessities, printing composites, medicine and food packaging and tape with its unique non-toxic, odorless, fully biodegradable, antistatic, easy to dye, good extensibility, high temperature resistance and other excellent properties. , Cables, insulating substrates, etc. However, cellulose does not melt and is difficult to dissolve. Therefore, in the industrial processing of cellulose, a multi-step and complex viscose process is used. The process is complicated and lengthy, the conditions are difficult to control, the energy consumption is large, the chemicals used are numerous, the toxicity and corrosion are strong, and the consumption is large. During the production process, a large amount of toxic exhaust gas and high acidity are generated, and it is difficult to treat wastewater. Therefore, it is of great economic and social significance to develop new and efficient green preparation techniques for cellulose films.
