How to measure the polishing effect of white marble colors?

Gloss is a problem that everyone pays attention to in white marble colors care engineering.Many people even use it as the only measure of the quality of the carrera marble colors project.The higher the gloss the more proof that the project is doing well. But in fact, the degree of gloss is only one of the factors that determine the effect of marble tile company decoration.

The size of the gloss depends, on the one hand, on the refractive index of the various minerals that make up the rock and on the other hand is closely related to the microstructure of the stone surface. The same granite stone has a certain mineral composition, the smoother the surface, the less the concave and convex defects, the higher the gloss of the stone.

In stone care, the microstructure of the stone surface is determined by the quality of the grinding and polishing process. The identification of the quality of the grinding and polishing is a very difficult task, because the surface of all the facing stone is bright as a mirror in our eyes. However, the surface of the finished stone after the actual grinding and polishing process is rough and the microstructure of the finished stone is rough and uneven after being enlarged by a high power microscope.

First, how to measure the polishing effect of stone?

Visual observation: When the stone maintenance is completed, it is recommended to first check the overall effect with visual observation. When looking at it, look at it from three perspectives.

(1) Vertical angle: The clarity of the stone can be checked.

Inspection method: Open the lamp on the roof and observe the outline of the light formed on the stone. In the place where there is no light, turn on the flashlight function in the mobile phone; or turn the screen brighter and place it on the surface of the stone 20~30cm.

The clearer the outline, the light is not scattered, the polished surface is crystal clear and the clarity is high.

On the contrary, after some projects are finished, although the test gloss is not low, it always looks like a circle of halo, and you can't see the clear outline of the light. It proves that the polishing is not enough, but the surface is smoothed, but the gloss is not clear.

(2) Sidelight angle: After observing the vertical details, we expand the scope of observation. Look at the maintenance effect by the angle of backlighting and smoothing.

Looking at the angle of the main light source, sideways. This angle can be used to check the brightness of the white marble colors stone, as well as the presence of chicken feet, craters, scratches, etc.

Follow the side of the main light source and observe it sideways. From this angle, when the carrera marble colors stone is the strongest light, it can check the color and pattern of the marble tile company.

Next we will observe the overall effect. Turn on all kinds of light sources. Such as opening doors and windows, turning on lights, etc. On a large scale, the overall effect is observed from various angles.

Second, accurate measurement of gloss

Measuring the polishing effect of stone, the visual experience is the most real. However, the application of stone to the entire decorative environment, the visual experience that people bring can sometimes not be completely explained by the gloss, but also pay attention to the visual overall sense.

So accurate measurement is a must, after all, the color and clarity of the stone have a great relationship with the polished and polished gloss of the stone. In general, the higher the gloss of the stone, the finer the surface is optimized.

Ground requirements: The measurement of gloss is calculated by the formula using the 60-degree reflection of light. Therefore, there is a requirement for the reflection effect on the ground during measurement. The ground must be clean and dry before measurement, and there is no pollution such as water and dust.

The surface gloss test of the stone plate with the specification larger than (600×600)mm can be applied to the nine-point test method, that is, three measuring points around the periphery and one measuring point in the center. Add the values and take the average.

This test method is based on the fact that natural stone is a material with a non-uniform distribution of minerals. The same piece of plate, the gloss of different areas, there is also a clear difference. Therefore, it is estimated that it is an average value.

In short, gloss is an important parameter to measure the quality of marble tile company maintenance. It is worthy of our attention, but it must be more objective. With the advancement of white marble colors care technology in China, our aesthetic level of carrera marble colors is also increasing. For example, some newly developed stone varieties are really difficult to produce high light, but the decorative effect is absolutely unbeatable.
