First, the scientific use of metal zipper:

 

1, pull the metal zipper, you must first on both sides of the tooth close to the top must be aligned, and then pinching the metal zipper head along the track gently pull, can not force too much pull.

 

2, when moving the metal zipper head should be careful not to skirt or cloth edge and other debris into the metal zipper, so as to avoid "tooth skew", "broken belly", "tooth" and so on.

 

3, if the metal zipper astringent, not easy to pull, do not pull hard, can be coated in the metal zipper wax or soap above, you can pull.

 

4, if the metal zipper head single-sided different points, wear loose, can be popular mountain Jun clamp in the metal zipper head side of the closed side of the light gently clamped, metal zipper is immediately changed for the better, unilateral teeth tight, no longer loose.

 

Second, to prevent the metal zipper damp, oxidation, rust and discoloration.

 

1, to avoid contact with the wet environment: because the metal zipper will be part of the metal oxidation caused by the phenomenon of black teeth.

 

2, to avoid contact with the rubber band: Because the rubber band itself contains sulfide, rubber band bundled metal zipper, the metal chain will produce sulfide (black).

 

3, washed and washed in time to dry: because the fabric of dyes or residual chemicals and metal parts of the redox reaction may cause metal parts discoloration.
