Marble is a high-grade decorative material, and marble stone is a natural material, which will be affected by many factors such as mining and processing. The quality of the marble stone product is quite different, and on-site evaluation is very important. The quality of the marble appearance can be identified from the following:
In a well-lit condition, place the selected plate and the same batch of other marble plates to be placed on the ground at the same time, and carefully observe them 1.5 m away from them. The pattern tones of the same batch of marble plates should be basically reconciled.
Under the condition of sufficient light, the plate was placed flat on the ground, and the invisible defects were observed at 1 m away from the marble plate. No defects were observed. The defects that were visible at 1 m from the plate and not obvious at 1.5 m were not obvious. Defects; defects that are apparently seen at 1.5 m from the sheet are considered defective.
The specific observed defects are sheet warping; there are cracks, blisters, discolored spots, stains and dents on the surface of the board. If it is determined that the above defects are not available, then the sheet is superior, and the front side of the sheet is not allowed to have missing corner defects; if the above defects are not obvious and there is no obvious missing corner, then the board can be considered as a grade. If there are several defects that do not affect the use, the board can be judged to be a good product.
Marble quality is a very important review project, and the success of the entire project is closely related to the quality of the marble.
