Description
The average weight of this metallized polypropylene film capacitor is approximately 33 g. This dataset includes major raw materials, energy consumption, and waste generated during the production process. Infrastructure such as manufacturing equipment and facility construction is excluded from the system boundary of this dataset. The life cycle inventory is compiled from data sourced from multiple references. The production of metallized polypropylene film capacitors consists of two main stages: film metallization and capacitor manufacturing. Film metallization employs vacuum deposition technology, involving processes such as pretreatment, vacuum deposition, post-treatment, crystallization, and slitting. Capacitor manufacturing includes winding, thermal pressing, welding, encapsulation, lead forming, testing, and sorting processes.
Activity Description
The production of metallized polypropylene film capacitors includes two main processes: film metallization (pre-treatment, vacuum deposition, post-treatment, crystallization, slitting, inspection) and film capacitor manufacturing (winding, hot pressing, welding, encapsulation, forming, testing and sorting).
Process Description
Metallized polypropylene film capacitors mainly consist of raw materials such as polypropylene base film, metal wire, encapsulation resin, lead wires, and lead foils. Downstream applications of film capacitors primarily include industrial control, lighting, household appliances, and new energy fields. In new energy vehicles, they are mainly used in inverters, on-board chargers, and charging stations.
