Appearance is a very important reference factor when choosing wall coverings. In order to accurately assess the gloss and color of wall coverings, you can use professional instruments to measure. This article brings you the application of Best Tri gloss meter products to verify the gloss of wall coverings.
The necessity of wall covering gloss test:
Common wall coverings mainly include cotton wall coverings, hemp wall coverings, and silk wall coverings. At present, seamless wall coverings are commonly used in production. It is mainly made of natural fiber textile materials such as silk, wool, cotton, and linen. When consumers choose wall coverings, they often make selections based on their appearance quality, such as whether they are shiny, chromatic aberration, wrinkles, bubbles, and so on.
Luster is an attribute of an object related to the reflective properties of the surface. The quantitative expression of gloss is called gloss. Although luster is the lustre produced by the reflection of light by an object, from a psychological point of view, even when observing that kind of non-glossy object, there is a lustrous feeling. We generally call it psychological luster. Due to the complex surface structure of fibers and textiles and the semi-transparent nature of the material, in addition to the direction of the reflected light, the brightness distribution, internal reflection ratio and transparency are also affected by the gloss.
Best Tri gloss meter products determines the gloss of wall covering:
There are many ways to measure the gloss of wall coverings, such as three-dimensional contrast gloss and two-dimensional contrast gloss. However, what it can measure is limited to physical quantities other than the senses, and it is inevitable that there are areas that do not conform to visual reflections. There are two standards for visual evaluation of gloss: quantity (whether gloss is present) and quality (whether gloss is good or not). It is usually carried out by a certain number of experienced evaluators under a standard light source illuminated at a prescribed angle (for example, 45°). The visual gloss of the sample can be evaluated by pairwise comparison or rank ranking method. The disadvantage of the visual evaluation method is that the visual perception is easily affected by the incident angle and the receiving angle of the light and the individual difference of the evaluator, so the reproducibility is poor and the evaluation criterion is not stable enough. The ideal gloss test method should have good reproducibility, not be affected by individual differences, and be consistent with the sensory order.
In the process of industrialization, in order to control the quality of fabrics, fabric Best Tri gloss meter products can be used to test various fabric structures and fabrics of different colors to evaluate fabric gloss. The measurement principle is: the light source emits parallel light and irradiates the sample with an incident angle of 60°, and the detector is at the position of 60° to measure the regular reflection light and diffuse reflection light from the fabric, which are used for photoelectric conversion and analog-to-digital conversion. The number shows the light intensity, and the contrast gloss (that is, the ratio of the intensity of the regular reflection light to the intensity of the diffuse reflection light) represents the gloss of the fabric.
