Sanding belt suspension
Before the sanding belt is used, it should be suspended for at least 2-5 days. Its purpose is to eliminate the curl caused by the packaging. Hang the unpacked abrasive tape on a 100-200mm diameter tube or on a dedicated sanding belt support. The length of the tube should be greater than the width of the abrasive sanding belt, otherwise the sanding belt can easily fall off or generate a bell mouth; the tube should be in a horizontal state, otherwise it is easy to damage the edge of the sanding belt. The ambient temperature and humidity of the suspended sanding belt should be in accordance with the storage conditions of the sanding belt. The simplest method is to keep it dry in a sealed room with several 40W or 64W bulbs.
