  1. Basic requirements for product storage

  1. The enameled wire packaging boxes should be stacked in plates, the stacking height should not exceed 4 boxes, and the maximum stacking of spools should not exceed 5 axes.

  2. The enameled wire should be kept away from dust (including metal powder), avoid direct sunlight, prevent high temperature and humidity, and never store it in the open air.

  3. The enameled wire should be stored in a dry and ventilated warehouse with a temperature of 0~35℃ and a relative humidity of 10%~70%. There should be no harmful to the enameled wire in the storage environment.

  Corrosive gas.

  4. Check the quality of the enameled wire in stock on time, and deal with the unqualified products in a timely manner to prevent the unqualified products from being put into production.

  5. It should be classified and placed according to different types and specifications, and it should also be classified and placed according to different manufacturers to prevent confusion.

  6. ​​The warehouse should be absolutely first-in-first-out when shipping to prevent long-term backlogs and deterioration. Under normal storage and operating conditions, from the date of delivery, single-coated enameled wire

  The quality validity period is 18 months, and the composite enameled wire quality validity period is 6 months. If it is expired, the product quality should be comprehensively inspected and evaluated before use.

  7. The warehouse staff should not be punctual and often check whether the stacked spools are deformed and broken to prevent the collapse of the phenomenon.

  2. Basic requirements for product protection

  1. The unused spools of the enameled wire should be placed in the original packing box, and should not be placed randomly. The label should protect the original condition.

  2. When necessary, the spools should be piled up high with partitions to prevent adverse effects such as moisture.

  3. When taking the spool, take it out vertically to prevent the wire from being bumped. At the same time, pay attention to the collapse of the left and right wire stacks.

  4. The unused wire must be wound tightly, not loose on the spool at will.

  Third, the basic requirements for product use

  1. Before use, carefully check the appearance, specification and type of the enameled wire to prevent the occurrence of defective products due to misuse.

  2. The paint film on the surface of the enameled wire is very thin, and it is easily damaged by external forces. During transportation or moving, pay special attention to handle it carefully to prevent dumping and bumping, and to ensure that the wire is not damaged.

  3. During winding operation, the enameled wire paint film is easily scratched by hard edges such as metal. During the winding process, pay close attention to the parts of the winding machine in contact with the enameled wire, reduce unnecessary external forces on the enameled wire, and prevent quality degradation. If bumps or multiple thread ends are formed accidentally, the part can be cut and removed with pliers, and then used in the normal part. The pay-off device that unreasonably affects the quality of the thread should be thoroughly improved as soon as possible.

  4. The wire tension should be controlled within the safety tension during the winding operation, and the force should be adjusted according to the actual production situation. At the same time, do not use rags to clamp the wire, which will cause the lubricating grease on the wire to dry out, reduce the surface lubrication performance, and eventually cause secondary quality abnormalities.

  5. When winding the wire, if it is necessary to directly touch the enameled wire with your hands, you should wear latex finger cots. Before winding the wire, check whether the outer edge of the wire reel is lubricated and free of barbs to prevent the formation of enameled wire wounds. When the winding operation reaches the bottom of the cylinder, the speed should be moderately slowed to prevent possible risks caused by the twisting of the high-speed winding end.

  6. ​​When the wire is wound, the paint film may be damaged due to high-speed winding, and the salt water pinhole performance will decrease. Therefore, the salt water pinhole performance of the enameled wire after winding should be confirmed.

  7. During soldering operations, the paint film will decompose harmful gases, so an exhaust device should be installed on the job site.
