As a kind of natural product, stone is more and more popular with the public because of its natural beauty and non-sexy characteristics. However, it is undeniable that it is precisely because stone is a natural product that there are many unsatisfactory places. Therefore, in order to meet the needs of customers, we need to deal with the natural defects of the stone. Then, what are the methods for dealing with the defects of the natural stone? Next, let's take a look with the editor of FABULOUS Group.

　　1、color difference stone

　　Although it is said that the chromatic aberration of natural stone is inevitable, some customers still do not approve of the chromatic aberration. Dye the color difference stone or use other stone instead. For dyed stone, it needs to be recognized by customers first. Don't pretend to use dyed stone to pretend to be a first-class product. For and even dyed stone, the table color should be even, the color fastness should be good, and the color should not be faded.

　　2、 the degree of polish is not up to standard

　　Due to their own processing technology or cost considerations, some stone processing factories did not grind the stone to meet the contract standards or the required gloss, so they used varnish, wax, and light film methods to increase the stone slabs. The glossiness of the surface meets the luminosity required by the contract (generally above 90 degrees). The effect of this is also very bad, like oiling and waxing, it may be exposed before the installation (or the installation process), and although the coating is better, once the layer of light film is worn away It is also revealing, it is quite dangerous for some orders with a delivery period, and the money and goods may be out of stock.

　　3、 black bladder and stains and other blemishes

　　For black gall spots of stone, it is generally treated with strong oxidants, which is the same in most factories. However, there is a difference between good quality factories and poor quality factories. A good quality factory will process after rough grinding, then rinse it without leaving any oxidant residue, and then perform fine grinding. For factories with poor quality control, they are polished first, and then processed after picking out defective stones such as black gall slabs when inspecting the goods. Apply strong oxidizers on site and rinse them on site to dispose of the stone slabs. Basically, it will be accepted by quality inspection.

　　In fact, this is also problematic. First of all, because the polished board is corroded by strong acid or alkali, the surface of the board is damaged and the gloss is reduced. Secondly, when the strong oxidant is washed on the spot, it is necessary to rush to pack it, which will cause the strong acid or alkali on the stone plate to be unclean, and the residual strong oxidant will continue to undergo oxidation reaction, causing problems such as color difference and whitening to damage the board surface. Moreover, due to being washed by water, these strong oxidants will flow to other places and cause secondary pollution. The pollution range is often much larger than the place where it is applied.

　　4、Stone with holes on the board

　　Some manufacturers use wax to repair. This is very unsafe. The correct way to repair is not wax but epoxy resin with the same or similar color as the stone surface. Use wax to repair the holes. Once the wax falls halfway or melts due to factors such as sun exposure, high temperature environment enclosed in the container, or fumigation, the holes will still appear at the end. Originally, the board surface was very good when the goods were inspected. But when it came to the customer, there were holes in the board.
