The anti-static ESD dust-free cleanroom wiper is made of 100% polyester fiber, with soft surface, easy to wipe the sensitive surface, no fiber removal by friction, good water absorption and cleaning efficiency. The cleaning and packaging of products are completed in the super clean workshop. Optional edge banding of dust-free cloth generally includes: cold cutting, laser edge banding and ultrasonic edge banding. Superfine fiber dust-free cloth is generally perfectly sealed with laser and ultrasonic; Static electricity is an objective natural phenomenon, which occurs in many ways, such as contact, friction and so on. Static electricity is characterized by high voltage, low electricity, small current and short action time. Static electricity is a static charged charge. Most static electricity is usually caused by friction and separation. Friction causes heat and makes the molecules in the material active. Then two substances are separated, and the transfer of electrons from one substance to other substances may occur.
