Moisture-proof storage of ABS wire in 3D printing

[kiki126]

ABS wire is widely used in many industries such as electronics, automobile and home appliances because of its excellent mechanical properties, easy processability and cost effectiveness. However, ABS materials are hygroscopic and easily absorb moisture in the air, which affects their processability and the quality of the final product. Therefore, proper moisture-proof storage is essential to maintain the performance of ABS wire.

First of all, ABS wire should be stored in a dry, well-ventilated environment. The ideal relative humidity should be maintained between 40% and 60% to avoid prolonged exposure to high humidity. Warehouses or storage areas should be equipped with appropriate dehumidification equipment, such as industrial dehumidifiers, to ensure that the ambient humidity is within a controllable range. In addition, the storage area should be away from water sources and wet places to prevent moisture in the ground and air from affecting the ABS wire.

Secondly, ABS wire should be stored as far as possible to avoid direct contact with the ground. You can use a pad or shelf to store the wire off the ground, at least 20 cm above the ground. This can not only reduce the impact of ground moisture on the wire, but also facilitate daily cleaning and maintenance work.

In terms of packaging, it is recommended to use moisture-proof packaging containing PE (polyethylene) inner bag for packaging. PE inner bag can effectively isolate the outside moisture, but also can prevent ABS filament in the storage process from being contaminated. If conditions permit, you can put an appropriate amount of desiccant in the package, such as silicone packets, to further absorb the residual moisture in the package.

For the ABS wire that has been opened, it should be used as soon as possible or dried before resealing. Industrial ovens can be used when drying, and the temperature is controlled between 80 ° C and 90 ° C, and the time is generally 2 to 4 hours. This can ensure that the water in the wire is fully evaporated, restoring its original performance.

In addition, the storage of ABS wire should also avoid long-term exposure to sunlight. Ultraviolet light will accelerate the aging of ABS materials, causing them to turn yellow and brittle. Therefore, the storage area should be selected to avoid direct sunlight, or use facilities such as blackout curtains to block.

Finally, regular inspection and maintenance is also an important measure to ensure the moisture-proof storage of ABS wire. Periodically check the humidity and temperature of the storage environment to ensure that they meet standards. At the same time, for the wire with a long storage time, regular spot checks should be carried out to ensure that its quality has not changed.

In summary, by controlling the storage environment, reasonable packaging, proper drying and regular maintenance, ABS wire can effectively prevent moisture and ensure its good processing performance and product quality. Although these measures may seem simple, they are of great significance to improve production efficiency and reduce costs.
