Why PVA Sponge Roller Have Good Asorbent Performance?

PVA Sponge Roller has a strong ability to absorb water and water supply capacity,  and does not drip after absorbing full water. The PVA Sponge itself has many small voids, which are filled with air. When the sponge is pressed to absorb water, it is compressed to discharge its own air, and when it is released, it will return to the original shape at the same time to inhale the original air, on the one hand, there is atmospheric pressure on the one hand, there is water pressure on the other hand, and the high pressure will be balanced to the low pressure. At this time, the pressure around the sponge is relatively small, so the water will enter the sponge. If you have noticed that the water will sink after the sponge absorbs water, it is subject to atmospheric pressure and the effects of gravity.

PVA Brush Features:

1, with high quality water, excellent water absorption, water retention.

2, because it has soft elasticity when absorbing water, there will be no working defects, and it is close to the convex and convex of the working surface, there is no water absorption spots.

3, there is no ordinary fiber material as the substrate shedding phenomenon.

4, wear resistance, wear resistance, good acid and alkali resistance.
