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 What Is Engineered Wood Vs Particle Board 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 boat remodel vinyl floor that looks like wood 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 how to replace rotten wooden bench slats Europe and the Middle East surface can be some of the pits and bars covered, an increase of stone surface finish, thereby enhancing the stone gloss.
