山东吉凌化工178彩票注册科普荧光增白剂常识
Shandong Jilin Chemical Co., Ltd. general knowledge of fluorescent whitening agents
荧光增白剂是一种能吸收紫外光并激宣布蓝色或蓝紫色荧光的有机化合物,吸附有荧光增白剂的物质。
Fluorescent whitening agent is an organic compound that can absorb ultraviolet light and provoke blue or blue-purple fluorescence. It adsorbs substances with fluorescent whitening agent.
一方面能将照射在物体上的可见光反射出来,一起还能将吸收的紫外光(波长为300nm~40Onm)转变为蓝色或蓝紫色的可见光发射出来,蓝色和黄色互为补色,因此消除了物品基体中的黄色,使其显得皎白.另一方面因为增加了物体对光线的发射率,发射光的强度超过了投射于被处理物上原 来可见光的强度,所以,人们用眼睛看上去物体的白度增加了,然后到达增白、增艳的意图。
On the one hand, the visible light irradiated on the object can be reflected, together with the absorption of ultraviolet light (wavelength 300 nm-40 Onm) into blue or blue-purple visible light emitted, blue and yellow complement each other, thus eliminating the yellow in the object matrix, making it appear white. On the other hand, because of the increase of object pairs. The emittance of light exceeds the intensity of visible light projected on the treated object, so people use their eyes to see that the whiteness of the object increases, and then reach the intent of whitening and brightening.
从色彩学的视点来看,发生非五颜六色(无色相)视觉反响的光,一般称之为白光,白色是一种十分特别的色彩,它具有很高的亮度和极低的饱和度,可见光的波长范围在 400~760nm,这仅仅太阳光谱中很窄的一段。人们常误认为白光是 可见光谱范围内悉数波长光的总和,其实给定白度的白色光能够发生于两种或两种以上的单色混合光,含有两种波长成分的单色混合光也能够组成白光,并把这 两种光的色彩称为互补色。
From the point of view of color, the light that produces non-colorful (colorless) visual response is generally called white light. White is a very special color. It has high brightness and very low saturation. The wavelength range of visible light is 400-760 nm, which is only a very narrow part of the solar spectrum. It is often mistaken that white light is the sum of all wavelengths in the visible spectrum. In fact, given the whiteness, white light can occur in two or more monochrome mixtures, and monochrome mixtures containing two wavelength components can also form white light. The color of these two kinds of light is called complementary color.

荧光增白剂一般分为三种离子形状,即阴离子型、阳离子型和非离子涣散型。这三种离子型的荧光增白剂在使用中的目标存在着必定的不同。一般来说,阴离子型荧光增白剂类似于直接染料、酸性染料,首要使用于棉、羊毛、锦纶的增白,使用环境一般要求PH值在7以下;阳离子型荧光增白剂则类似于阳离子染料,首要用于腈纶的增白,使用环境一般要求PH值在7以上;非离子涣散性荧光增白剂类似于涣散染料,首要使用于涤纶和醋酸纤维的增白,对PH值要求相对较宽。当然,有些荧光增白剂适合于多种纤维的增白,这要依据具体情况而定。总的来说,荧光增白剂在纺织品上的增白作用除了受其自身化学结构影响外,纺织品的性质、水质、染浴的PH值、助剂、颜料染料以及纺织品的后处理等也是重要影响的因素。
Fluorescent whitening agents are generally divided into three ionic shapes: anionic, cationic and non-ionic dispersion. The objectives of these three ionic fluorescent whitening agents are different. Generally speaking, anionic fluorescent whitening agents are similar to direct dyes and acid dyes. They are mainly used for whitening cotton, wool and nylon fibers. The environment generally requires that the PH value be below 7. Cationic fluorescent whitening agents are similar to cationic dyes, and are mainly used for whitening of acrylic fibers. The environment generally requires that the PH value be above 7. Ionic dispersive fluorescent whitening agents are similar to those of disperse dyes. They are mainly used for whitening polyester and acetic acid fibers, which require relatively wide PH values. Of course, some fluorescent whitening agents are suitable for whitening many kinds of fibers, depending on the specific circumstances. Generally speaking, the whitening effect of fluorescent whitening agent on textiles is influenced not only by its chemical structure, but also by the properties of textiles, water quality, PH value of dyeing bath, auxiliaries, pigments and dyes, and the post-treatment of textiles.
塑料、油漆、涂料、造纸等荧光增白剂作业原理也是如此,依据类似相溶和光学增白原理,使用分子链相融和分子结构官能团具有吸收必定波段内的黄色光反射出来蓝白光去进行光学增白,这种增白原理不会改变物体自身色彩,只让白色的更白、五颜六色的更亮更艳!所以不用忧虑产品被漂白,能够放心使用。
The same is true for fluorescent whitening agents such as plastics, paints, coatings and papermaking. According to similar principles of miscibility and optical whitening, optical whitening can be achieved by using molecular chain blending and molecular structure functional groups with yellow light reflecting from blue and white light in a certain band of absorption. This whitening principle will not change the color of the object itself. Only white, colorful, brighter and brighter! So don't worry about bleaching products, you can use them safely.
