Will chemical injuries occur to people who work in NMP(1-Methyl-2-pyrrolidinone) or battery factory for a long time?

Through the foreign media website, the editor learned that the chemical NMP(1-Methyl-2-pyrrolidinone) has a certain impact on the human body.
Therefore, protective suits are necessary for staff working in NMP(1-Methyl-2-pyrrolidinone) production factory;
The staff who work in the lithium battery factory and assist the battery factory to monitor the NMP recycling equipment have also taken adequate safety measures when conducting NMP waste liquid detection and monitoring.
As we all know, although there are many different types of batteries on the market, lithium batteries are currently the first choice for new energy vehicle power batteries.
The production process of lithium batteries is very complex and involves a variety of raw materials. Among them, the transparent solvent N-methylpyrrolidone (NMP, Cas no. 872-50-4) is consumed hugely in the production of lithium batteries.
The main function of the NMP ((1-Methyl-2-pyrrolidinone) solvent is to act as a solvent for the positive electrode slurry during the production process, which is used to dissolve the binder PVDF and disperse the active material;
In the coating and drying process, the NMP solvent can be recovered through the recovery system (Zesheng New Materials can provide this equipment).
NMP waste gas generally adopts closed cycle, and the recovery efficiency of NMP (N-Methyl-2-pyrrolidone) on the market can reach 85%~95%;
However, after monitoring by Zesheng New Materials team and using the NMP recovery equipment developed by our company to collect, the recovery rate of NMP waste gas can reach more than 98%.
In view of the huge amount of NMP solvent consumption and waste liquid generation in the lithium battery industry, if there is no equipment with higher recycling efficiency and no professional team monitoring,Then the long-term spilled NMP (N-Methyl-2-pyrrolidone) waste gas will have a certain impact on the factory workers and the surrounding environment.
Therefore, the Zesheng New Materials team suggests that the following two points should be considered whether purchasing NMP (N-Methyl-2-pyrrolidone) solvent or purchasing NMP waste gas recovery equipment:
- Investigate the professionalism of the service team;
- Confirm whether the partner can provide you with more professional recycling equipment with higher recycling efficiency.
Coincidentally, the Zesheng New Materials team has been focusing on the lithium battery industry for more than 10 years and has rich industry experience;The Zesheng New Materials team maintains long-term cooperative relations with well-known domestic battery factories, and has a better understanding of the battery factory’s preparation process and NMP (N-Methyl-2-pyrrolidone) waste gas recovery, and can provide you with more professional NMP use and recycling solutions.
Let professional people do professional things, improve work efficiency, but also save project costs. Looking forward to your cooperation inquiry~
