How to judge whether the surface treatment of density board is sanding or calendering?

Necessary professional training is indispensable for new people to learn. Through recent training, a problem has been found, that is, the distinction between sandboard and calender is often unclear.

In fact, as long as we grasp the differences between the two, it is clear to distinguish them.

Sanding is to make the surface of the board smooth and increase the strength of the surface, uniform thickness, suitable for various veneer technology, suitable for various standard structural parts, easy to decorate and make tools.

Sanding, as its name implies, is a calendering board. In order to get a board that is easier to paste decorative materials, it is sanded by a sander. Take a list, just like a bicycle tire repair. In order to paste rubber, a repair engineer will polish the tire. So the sanding board is a little thinner and slightly rougher than the calender.

Calendering is the hot pressing or cold pressing of an object by means of rollers, with the aim of improving the surface finish of the object. Calendering process has a wide range of uses: density plate production, mechanical processing, printing, textile, metallurgy are used calendering process.

To master the above knowledge, I believe that when we distinguish sanding board and calender again, a sentence “so easy!” It will be a common word.
