How to detect the gloss of matte bricks? This article will briefly introduce the method of using the gloss tester to detect matte tiles.

What is the gloss of matte brick?

Matte tiles are tiles with relatively low gloss, which are usually suitable for kitchen and bathroom floors.

At present, there is no uniform standard for the gloss of matte tiles. Different enterprises will divide the tiles into matte tiles and polished tiles according to user needs. Compared with polished tiles, matte tiles are non-bright surfaces, which can avoid light pollution and are more convenient to maintain. But it is easier to get dirty and not easy to take care of.

Highlight and matt refers to a characteristic of the surface of an object. Objects can be divided into highlights, semi-gloss, mercerize, soft light, and matte according to the difference in gloss. Most objects in nature are neither completely specular nor completely matte. Usually the gloss can be measured with a professional gloss tester.

Method for measuring the gloss of matte bricks

Whether the surface of an object is high-gloss or matt can usually be easily distinguished by the naked eye. However, it is difficult to compare the difference in surface gloss of two objects that are both high-gloss or matt. In order to accurately assess the surface gloss of high-gloss and matte objects, professional gloss instruments are needed. Most gloss testers measure the surface reflectance of an object, which is called a specular gloss tester. 

The measurement results are different depending on the angle of incidence selected during the measurement. The larger the angle of incidence, the greater the specular reflectance and the higher the gloss. That is why high-gloss materials should be measured with a high-gloss measuring instrument at a 20-degree angle; otherwise, the lower the specular reflectance, the lower the gloss. Use a low gloss tester with an 85-degree angle. It can be seen that the level of gloss depends not only on the surface characteristics of the object, but also on the measuring angle of the instrument.

Generally, the 60-degree angle is commonly used on the market, like the universal 60-degree gloss tester LS192 from Linshang Technology with a range of 1000GU, high gloss and low gloss All materials can be tested because the gloss is a relative value. When there is no uniform standard in the applied industry, it can be tested with the LS192 gloss tester. If the industry has a uniform standard, it is best to use the same angle of testing. Therefore, when selecting the measurement angle, you should choose differently according to different situations.
