Therefore, in the purchase of granite stone, the quality of stone grinding and polishing is essential to identify. If you do not master some of the skills, the grinding of the quality of grinding is a very difficult job, because in our naked eyes all the finishes of the surface of the stone are bright as a mirror. However, after the actual grinding and polishing after plastic privacy deck panel Australia the surface of the stone surface no matter how easy it looks, after the high magnification microscope, the performance of the microstructure is rough, and sometimes even a large flaw.

In the eyes of the surface of the granite stone surface, in the reflective microscope and under the scanning electron microscope photos, from the figure we can see the surface of the stone there are grinding and polishing in the left after Composite Floor Manufacturer the pit and These pits and streaks are caused by the defects of the mineral itself which can not be overcome under the current processing conditions, and some because of the irrational grade of the millstone in the course of processing, Caused. To observe these very subtle defects, we need to be very careful and meticulous, but also to master a certain method.

We can handle the stone surface facing the sun or fluorescent lamp, observe the reflective surface can be clearly found as shown in the various pits and streaks, for those irregular small pits may 2017 low cost composite plastic decking be composed of some of the stone mineral Their own defects caused by, you can not consider, and if the surface of the stone found some regular stripes, it is due to poor processing quality caused by the purchase should try to avoid such a stone. Stone surface is waxing in some small stone processing plant, in order to save costs, but also to make their own stone to achieve high gloss, then on the one hand to reduce the stone grinding and polishing process, shorten the processing time, on the other hand After the stone polishing process in the stone surface marked with a thin layer of paraffin, so that the stone 2 x 6 plastic composite wood floor surface can be some of the pits and bars covered, an increase of stone surface finish, thereby enhancing the stone gloss.
