The difference between the use of oily and water-based abrasives Oct 15, 2018

The difference between the use of oily and water-based abrasives

Because the oil-based abrasive has a large oil-containing ratio, it is easy to cover the scratches during construction, so that the construction workers mistakenly believe that the scratches have been processed, but the scratches still exist. This is what we call "false grinding". Therefore, when using oily abrasives, it is necessary for the construction personnel to judge whether the scratches are completely removed during the polishing process, and to avoid the construction quality due to the characteristics of the oily abrasive itself. In addition, the oily abrasives have a large dust during construction, which will prolong the construction time in the later collection. The advantages of the oily abrasive are also obvious. Because of the high oil content, after the polishing, the paint surface will be very bright, and the visual effect is also very good.

Compared with the oily abrasive, the water-based abrasive has the advantage that there is almost no "false grinding" phenomenon when the scratch is processed, which greatly improves the accuracy of the judgment at the time of construction. When the construction personnel use the water-based abrasive, if the paint surface is not scratched, it will prove that the scratch has been removed. Moreover, since the water-based abrasive is small in particle size, the dust is not large during construction, and the subsequent light-receiving time is accelerated, and the human respiratory tract is stimulated at a small time.
