Reflective film is mainly used in road traffic signs, safety signs, construction signs, advertising signs and other signs, signs and other fields.
The reflective film should be stored in a ventilated and dry room with a temperature of 18-24 ℃ and a relative humidity of 30-50%. The packing box shall be placed on the pallet or base plate, and shall not be directly landed on the ground; the number of stacking layers shall not exceed 5. After purchasing the reflective film, it is required to use it within one year.
Uncoiling or cutting operation environment: the reflective film shall be placed at 25 ± 3 ℃ and 30-50% relative humidity for more than 24 hours before operation. Make sure the workplace and tools are clean.
It is recommended that operators wear silk or cotton gloves to avoid damaging or polluting the reflective film surface.
The cut reflective film shall be placed on a flat and smooth platform, and the platform area shall be larger than the cut reflective film area. If it is not used temporarily, the plastic bag shall be put on and tied tightly to prevent moisture absorption. The films of the same shape and size must be stacked neatly, and the stacking height shall not exceed 3cm, and no heavy objects shall be pressurized.
The reflective film with a length of more than 3m and a large area shall be tightly rolled on the paper tube (the inner diameter of the paper tube shall not be less than 100mm), fixed with three adhesive tapes and placed vertically on the plastic bracket to avoid “tunnel” phenomenon. The opened sheeting should be used as soon as possible. For the unused reflective film, the edge of the film shall be tightened and rolled onto the original paper tube, and more than three places shall be fixed with adhesive tape. Plastic brackets shall be installed on both ends of the paper tube, and the plastic bags shall be put back into the original cartons after being covered. Or put an iron bar in the center of the reflective film paper tube and place it horizontally on a special shelf or vertically on a plastic bracket. Do not throw the unused reflective film directly on the ground or lean against the wall.
Three. film application method
Material selection: It is recommended to stick on clean, flat aluminium or stainless steel plates correctly treated. It is not recommended to directly stick on the surface of plastic, rubber, wood and other base materials. If it needs to be pasted on the base material of non aluminum plate or stainless steel plate, the user shall determine the application adaptability of the reflective film.
Base material treatment: the surface of aluminum plate and stainless steel plate which just leave the factory is very smooth, which is not conducive to pasting. It needs to be polished with 400-500 sandpaper in the arc direction. Before pasting, it must be scrubbed with degreasing solvent, washed with clean water and dried.
