The important accessories of the trolley duffel case are sliders, zippers, trolleys and wheels, among which zippers are frequently used. For the maintenance of the zipper, we must use it scientifically to extend its service life. The manufacturer will introduce the maintenance techniques of the trolley duffel case zipper below. 1. In normal use, when pulling the metal zipper of the luggage duffel
, the teeth on both sides must be close first, the tops must be aligned, and then the metal zipper pull of the metal luggage duffel should be gently pulled along the track, not too hard. Pay attention to whether the zipper has any shortcomings such as 'broken bellyIf the zipper is loose and out of teeth, you can tap a small hammer on the zipper head a few times to make the upper and lower sprocket bite tighter, so that the teeth will not fall off; 2, aluminum alloy zippers are more susceptible to corrosion, so It should be kept dry and not exposed to moisture to prevent the aluminum teeth from generating white oxides, which will cause the zipper to rust over time, which will affect the use. At the same time, be careful not to contact with alkaline and acidic substances. Ensure a certain degree of ventilation during storage. Do not store in a sealed or humid environment. Use moisture-proof paper or dehumidifier when necessary. If the zipper gets damp and becomes astringent when it is pulled up, at this time, first dry the zipper, then apply some wax on the teeth of the zipper, and then bake it with fire, so that it will be very smooth when used; 3. Metal zippers for luggage duffel and bags
made of copper alloy (white copper, copper, brass), when used on metal products or wool products, metal zippers will cause some of the teeth to become black due to metal oxidation. If the zipper is astringent and the pulling is not sensitive, you can wipe it with a cloth first and then apply a layer of white wax on the 'teeth'; 4. Although the metal zipper head has been pre-treated with anti-rust treatment, it is the attribute of metal due to oxidation. In order to reduce discoloration and surface scratches, the manufacturer recommends wrapping the metal zipper head with copy paper, or putting a dust bag on the trolley case.
