Storage Method Of Sand Belt

The storage of sand belts is crucial for their use, with a particularly greater impact on wide sand belts. Ideal storage conditions and reasonable storage methods are necessary to ensure that the sand belt is used in good condition.

1.1 Temperature and humidity requirements

Ideal temperature: 18 ℃~22 ℃

Ideal humidity: 40% to 65%

Sandbelts should not be stored in places with significant temperature and humidity changes. Excessive temperature can cause the binder to age and reduce the service life of the sandbelt; Synthetic fiber substrate sand belts (such as polyester cloth sand belts) are sensitive to cold and cannot be stored in cold warehouses.

Excessive or insufficient humidity can cause deformation of the sand belt, which can reduce the bonding strength of the sand layer. Especially when the humidity is too high, the impact on the sand belt is quite serious. Except for the water-resistant sand belt, the sand belt is generally prone to folding, wrinkling and other phenomena when used after being damp, which can cause the sand belt to be scrapped. In addition, damp abrasive belts can easily adhere to the surface of the belt during grinding, reducing the service life of the belt.

High temperature and low humidity have a significant impact on paper-based sand belts, making them brittle and prone to breakage and scrapping during use.

1.2 Storage

The warehouse for storing sand belts should be cool, dry, and well ventilated; Sandbelts should be placed on the cargo rack and not on the ground; The cargo rack should maintain a distance of about 200-500mm from the ground and walls, while also avoiding proximity to heat dissipation and drainage devices; Try not to open the packaging box for unused sandbelts. Heavy objects should not be stacked on the sandblasting packaging box to avoid creases and cracks caused by the sandblasting.
