Surface Static Electricity Problem of Biaxially Oriented Polypropylene Film Products
Fenómeno do problema
Static electricity easily accumulates on the product surface, attracting dust or causing damage to electronic components.
Análise das causas
(1) The volume resistivity of ABS variant is high, and static electricity is not easily released
(2) No antistatic agent is added or the amount is insufficient
(3) The ambient humidity is low, and static electricity easily accumulates
(4) Static electricity is generated during friction processing
(5) The surface treatment of the product is insufficient
Solução
(1) Add an antistatic agent (0.1-0.5%)
(2) Use a permanent antistatic agent or conductive filler
(3) Increase the production environment humidity to 50-60%
(4) Ground the equipment to eliminate static electricity accumulation
(5) Coat the product surface with an antistatic coating
Conclusão principal
The static electricity problem is caused by the high insulation of the material.
