Before adding liquid, with the product grinding work-piece of drying regime.
Now will be only by way of example with reference to Fig. 1 description present invention, Fig. 1 shows the cross across abrasive product of the invention
Section.
Fig. 1 is shown with the abrasive product of the form of abrasive disk 10.Disk 10 is adapted to mount to rotary polisher or eccentric orbit
Formula sander, but within the scope of the invention it is contemplated that abrasive product can be used for the grinding work of other forms.Disk 10 has
Backing 12, the backing 12 have opposite the first main surface 14 and the second main surface 16.First main surface 14 carries adhesive layer 18.
Abrasive coating 20 is located on bonding coat 18.
Backing 12 is formed by non-woven thermoplastic web, and the non-woven thermoplastic web is included at it contacts with each other
It is bonded to mutual opening, bulk three-dimensional fibrous structure.Such non-woven backing is well known in the art.Optionally
Embodiment in, backing 12 be foam-back, and within the scope of the present invention it is contemplated that other forms backing.Back lining materials
