Preparation Before Use Of Sanding Tape

1 Sandbelt suspension

The sand belt should be hung for at least 2-5 days before use, with the purpose of eliminating curling caused by packaging and adapting the sand belt to the environment of the place of use. Hang the unpacked sand tape on a pipe with a diameter of 100-200mm. The length of the pipe should be greater than the width of the sand belt, otherwise the sand belt is prone to falling off or producing a trumpet mouth; The pipe should be in a horizontal state, otherwise it is easy to damage the edge of the sand belt.

The environmental temperature and humidity of the suspended sand belt should meet the storage conditions of the sand belt. A simple method is to use several 40 or 60 watt light bulbs in a sealed room to keep it dry.

2 Appearance inspection

The suspended sand belt should undergo necessary visual quality inspection before use to check whether the sand belt joints are flat and firm; Whether there are appearance defects such as holes, sand clumps, lack of sand, adhesive spots, wrinkles, etc. on the surface of the sand belt; Whether the edges of the sand belt are neat and without cracks. If there are small cracks on the edges, they should be cut in a circular arc without affecting their use.
