Nowadays artificial marble already is the durable consumable of common people, to product quality also is requirement more and more strict.However, as aluminum hydroxide, which occupies more than 60% of the addition of artificial marble, its quality directly affects the processing technology and product quality of artificial marble.
Chroma is one of the important indexes to measure the quality of aluminum hydroxide products.Chromaticity includes non-color series whiteness index, color series lightness, hue and saturation index, in these index, whiteness and a, b value have the greatest influence on the application of the product.
In theory, color is a general term for color and color.Anachromatic refers to white, black and various shades of gray, gradually from white to light gray, medium gray, dark gray, until black, arranged in a series, which is called white and black series.The change from white to black in the white and black series can be represented by a straight line, with pure white on one end and pure black on the other, with transitional shades of grey in the middle.Pure white is the ideal completely reflective object, while pure black is the ideal non-reflective object.
The whiteness is based on the monochromatic absolute reflection ratio of the standard white board of magnesium oxide to a specific wavelength, and the absolute reflection ratio of the sample surface is measured by the corresponding wavelength, expressed as a percentage.The baidu of white pottery and porcelain board, it is to point to take pure white pottery and porcelain as standard white board to the absolute reflection ratio of the monochromatic light of specific wavelength, express with a percentage.In the aluminum hydroxide industry has not established the determination of whiteness standards, according to the production situation and user requirements, with the ceramic white board as the standard to determine the whiteness of aluminum hydroxide, and with the full automatic color meter to measure the whiteness value.
Color refers to white and black series of unexpected colors.
Color has three properties: lightness, hue, and saturation.Among them, lightness also calls brightness, it is bright with dark contrast, the light reflection of color object surface is higher, lightness is higher, the human eye feels more bright.Tonal call hue also, it is the characteristic that color distinguishes each other.Such as red, orange, yellow, blue and so on.Saturation also known as color, refers to the purity of color, the visible spectrum of a variety of monochromatic light is the most saturated color.These three properties allow you to define the position of any color in the color space.
