Metalized piastic sheet for lifting a single dust footprint
The front side is black high gloss PET insulating plastic film, the back side is a layer of aluminum electroplated, both sides have 10 mm wide insulating strip, and the upper end has a safe area. Hands in the safe area, not electric shocked
Purpose
Lift a single dust print on a flat surface.
Composition
A layer of aluminum is electroplated on one surface of the black PET plastic film with 35cm in length, 22cm in width and 0.1mm in thickness. On both long sides of the film, there are two black insulating strips (10mm wide). The short side 1 is wrapped with an insulating plastic sheet to form an insulating strip. The short side 2 is completely electroplated with no insulating strip.
Specifications
| Base material | PET |
| Electroplated material | aluminum |
| Thickness | 0.1mm |
| Dimensions | 35x22cm/each |
| Packing | 10pcs/bag |
Working principle
Charge the aluminized surface with static charge. The static charges flowing into the lifting film generate an electric field, which polarizes the dust under the lifting film and then adsorbs the dust prints to the lifting film. When the lifting film unfolds automatically, since both the long sides and the short side 1 have insulating strips, the electric charges cannot leak from any edge and the lifting film can be sufficiently charged. The static charges flowing into the lifting film generate an electric field, which polarizes the dust under the lifting film and then adsorbs the dust print to the black PET film.
Method
Hold the insulating strip of the short side 1 and lift the lifting film so that the short side 2 touches the ground and stays close to the footprint. Connect the lifter anode with the aluminized surface to charge it and lower the lifting film slowly, then the lifting film covers the footprint evenly and adsorbs the dust print to the lifting film.
Hold the insulating strip of the short side 1 and lift the lifting film so that the short side 2 touches the ground and stays close to the footprint. Connect the lifter anode with the aluminized surface to charge it and lower the lifting film slowly.
The electrostatic film is covered on the footprints, and the electric charge remaining in the coating layer generates an electric field, which adsorbs the dust under the electrostatic film on the black plastic surface of the electrostatic film
Take up and turn over the electrostatic film in the hand-held "safe area", and shine it with grazing incident light, you can see the white dust footprints on the black plastic film
