荧光增白剂会发光吗?

  荧光是一种冷发光的物理现象,比方儿时夜晚院子里榕树下的萤火虫,绚丽多彩的海洋生物水母、虾、蟹等,由于它们体内含有各种荧光蛋白质,所以会发光。
  Fluorescence is a physical phenomenon of cold luminescence, such as fireflies under banyan trees in the yard at night as a child, colorful marine jellyfish, shrimp, crab and so on, because they contain a variety of fluorescent proteins, so they will glow.
  在我们人体内也有能产生荧光的物质,如局部氨基酸,维生素A,荷尔蒙等。我们把能产生荧光现象的物质统称为荧光剂,它包括了工业消费的化学物质——荧光增白剂和一些能产生荧光的自然物质。
  There are also fluorescent substances in our body, such as local amino acids, vitamin A, hormones and so on. We collectively call the substances that can produce fluorescence phenomenon as fluorescent agents, which include chemical substances consumed in industry - fluorescent whitening agents and some natural substances that can produce fluorescence.
  荧光增白剂(英文Fluorescent whitening agents,简称FWA)是一种荧光染料,能吸收不可见紫外光(波长300~400 nm)后再激起出可见蓝色或者蓝紫色荧光(波长420~480 nm)的复杂有机化合物,普遍运用于纸、塑料等行业的消费中,以进步产品的白度和艳度的性质。
  Fluorescent whitening agents (FWA) is a fluorescent dye, which can absorb invisible ultraviolet light (wavelength 300-400 nm) and then stimulate visible blue or blue-purple fluorescence (wavelength 420-480 nm) complex organic compounds. It is widely used in the consumption of paper, plastics and other industries to improve the whiteness and brightness of products.

  全世界范围内报道的荧光增白剂约有15种根本构造类型,近400种化合物构造,而用于造纸和纸板的荧光增白剂中有将近80%的是源于二苯乙烯的衍生物,都具有环状的共轭化学构造,常用的是三嗪氨基二苯乙烯类荧光增白剂(DSD-FWAs),包括二磺酸、四磺酸和六磺酸三品种型。
  There are about 15 fundamental structural types of fluorescent brighteners reported worldwide, including nearly 400 compounds. Nearly 80% of the fluorescent brighteners used in papermaking and paperboard are derivatives derived from stilbene, which have cyclic conjugated chemical structures. The commonly used fluorescent brighteners are triazine aminodistilbene (DSD-FWAs), including disulfonic acid, tetrasulfonic acid and hexasulfonic acid tris. Variety type.

  固然小小的身躯,却具有大大的才能哦,他能够吸收不可见的紫外光(波长范围约为360-380nm),转换为波长较长的蓝光或紫色的可见光,因此能够补偿不想要的微黄光,同时反射出比原来入射波长在400~600nm范围的更多的可见光,从而使制品显得更白,更亮,更鲜艳。简单粗暴地说,FWA就是应用光学上的补色作用使白色或淡色物品增白增艳。
  Although a small body, but with great talent, he can absorb invisible ultraviolet light (wavelength range is about 360-380 nm), converted to longer wavelength blue or purple visible light, so it can compensate for unwanted yellowish light, while reflecting more visible light than the original incident wavelength in the range of 400-600 nm, so that the product appears whiter, brighter and brighter. 。 To put it simply and roughly, FWA is the application of optical complementary effect to whiten and brighten white or pale objects.
