Why does the velcro sanding disc fly away from my sander?

Hook ring grinding disc vs stick to the grinding disc
For heavy-duty sanding applications using orbital sanders, optical discs that have been attached to optical discs have been chosen for many years. But as technology advances, these are now antiques. The biggest advantage of adhesive discs is that they get stuck and do not fly away, which makes them more reliable. The main disadvantage is that they produce a lot of dust and there is no simple or effective way to hold them.

The technology with discs has been transferred to abrasives supported by velcro or shackles. Now they are no longer solid discs, but have multiple holes, or in some cases they are made only of mesh, but I The main problem/complaint encountered is…

Why does the velcro sanding disc fly away from my sander?
The main reason for the non-sticking of the disc is due to the wear of the spare mat.

The spare pad has a nylon hook and loop for holding the velcro sanding disc in place. When the sandpaper gets hot during the grinding process, they become soft and melt, and the fixing force becomes smaller and smaller until the velcro sanding disc no longer sticks. So far away

When using an electric sander, you need to know a few things to make the most of the machine, abrasives and surfaces.

There are several steps you can take to get the most out of your strengths:

1 / Get a pad protector, a heavy-duty, very high-quality hook-and-loop sacrificial pad that protects bup pads from premature damage, and they are inexpensive but very effective.

2 / Connect to a vacuum cleaner. This has several benefits:

a / It will absorb the dust and physically remove it, which means that you are grinding the surface that needs to be polished. If not removed, you will continue to remove dust and push it back to the surface to effectively re-polish the same material.

b / Airflow keeps the backup pad cool, which means the hook ring does not easily overheat, soften and melt.

c / airflow also keeps the work surface cool and helps reduce blockage and pilling.

d / Dust-removing abrasives have an average service life of 30% longer than non-dusting abrasive disks.

e / Dust removal will greatly increase productivity, which means less grinding time, which not only makes you profitable, but also saves the tool wear and tear.

3 / Let the sander work, pressing hard will fatigue the user, tools and consumables. The sander should be allowed to rotate freely so that the orbital motion is normal.

4 / Once your backup pad can’t be resurrected, get a pad protector and stick it with contact glue so you can live longer without having to succumb to replacing it.
