Surface Static Electricity Problem of Biaxially Oriented Polypropylene Film Products
문제 현상
Static electricity easily accumulates on the product surface, attracting dust or causing damage to electronic components.
원인 분석
(1) The volume resistivity of biaxially oriented polypropylene film 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
해결 방법
(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
핵심 요약
The static electricity problem is caused by the high insulation of the material.
