Stone Surface Gloss Requirements and Detection Methods
1. Stone surface gloss requirements
The surface of the stone will have a certain gloss after the crystal surface treatment and waxing treatment. Different from the traditional waxing process, the crystal surface treatment process requires the stone to have a certain gloss and flatness foundation.
There is a difference between stone crystal surface and mirror surface. The crystal surface is hard and dense due to the hard and dense crystalline layer on the stone surface formed by the chemical and physical reaction between the agent and the stone. It can also be understood as crystal hard. After the hot saturated solution is cooled, the solution is precipitated in the form of crystals, forming crystals; such as marble calcification, granite silicification, etc. can form crystals, also known as crystal surfaces; stone mirror surface refers to the appearance of stone, generally waxing is the imaging of floor-forming objects. The surface is also called a mirror surface. After ideal treatment of the stone crystal surface, a hard and dense crystalline hard crystal layer can be formed on the surface. The surface gloss is closer to the mirror surface.
2. Marble gloss meter detects the quality of stone crystal surface
As for the gloss of the crystal surface, the traditional method is to observe directly with the naked eye and to evaluate the gloss of the surface. However, this method will be affected by the light source, observation angle and subjective evaluation factors of the observer. The measurement results are not accurate enough and it is difficult to quantitatively analyze the gloss. In order to control the quality of the stone crystal surface, you can use a marble gloss meter to measure.
Marble gloss meter is an optical instrument that measures the ability of specular reflection of the object surface with reference to a standard board. Under the conditions of the specified light source and receiver opening angle, it measures the light flux of the reflected light in the specular reflection direction of the sample. The reflected light flux of the standard sample in this specular reflection direction is compared and the obtained ratio is used as the gloss.
The stone surface glossiness testing requires the use of professional marble gloss meters. There are many types of marble gloss meters and the prices vary, but the principle is the same. Linshang LS192 marble gloss meter adopt 60-degree angle light source projection. Place the marble gloss meter on the stone crystal surface during measurement, under the light source and receiver angle conditions, the ratio of the reflected light luminous flux in the specular reflection direction to the reflected light luminous flux of the glass standard in the specular reflection direction is converted into data by electronic calculation and displayed on the LCD screen of the instrument. The LS192 marble gloss meter has a statistical function, which can display the maximum, minimum, average and standard deviation of the test. This feature can be used to analyze the uniformity of the stone crystal surface gloss.
Of course, the measurement angle of different marble gloss meters will be different. The user can choose the measurement angle according to the measurement requirement and then perform the measurement according to the glossmeter operation manual.
