荧光增白剂用途
荧光增白剂用途荧光增白剂是一种广泛应用于纺织、塑料、洗涤剂、纸张等行业的白色颜料。
荧光增白剂通过吸收紫外光，并将其转化为可见光，从而使物体表面呈现出更加明亮白净的效果。
荧光增白剂的主要成分为荧光增白剂ER、荧光增白剂OB等，它们可以吸收280-400纳米的紫外光，然后以蓝光或绿光的形式发射出来。
荧光增白剂主要的用途如下：1. 纺织工业：荧光增白剂广泛应用于纺织品的染色和整理过程中，可以使纺织品呈现出更加白净、明亮的颜色。
同时，荧光增白剂还能够在室外光线下吸收紫外光，然后发射出蓝光，进一步增强纺织品的白度，提高其质感和附加值。
2. 塑料工业：荧光增白剂可添加到塑料制品中，以增加其光洁度和透明度。
在塑料制品的生产过程中，荧光增白剂能够与塑料分子相互作用，使塑料表面呈现出明亮的效果，同时可以屏蔽掉塑料颜料中的杂色，提高塑料制品的质量。
3. 洗涤剂工业：荧光增白剂是洗涤剂中的一种重要成分。
通过添加适量的荧光增白剂，可以使洗涤剂中的洗衣成分在洗衣液中更加均匀分布，并能够增加衣物的白度和明亮度。
同时，在洗涤剂中添加荧光增白剂还可以在洗衣过程中发出蓝光，提高洗涤剂的增白效果，使衣物更加清洁。
4. 纸张工业：荧光增白剂是制造光面纸、包装纸等各类纸张中的一种重要添加剂。
在纸张的生产过程中，通过向纸浆中添加适量的荧光增白剂，可以增加纸张的白度和亮度，使其更加吸引人。
尤其是在高品质印刷品制作中，荧光增白剂能够使印刷品呈现出高对比度、高色彩饱和度的效果。
5. 墨水工业：荧光增白剂是彩色墨水和草图墨水中的一种常见成分。
通过添加荧光增白剂，墨水可以在黑色或彩色的字迹下呈现出更加鲜艳的颜色，使字迹更加清晰可见。
总的来说，荧光增白剂在纺织、塑料、洗涤剂、纸张和墨水等行业中发挥着重要的作用。
它不仅可以提高产品的白度和明亮度，增加产品的附加值，还可以使产品更加吸引人。
因此，荧光增白剂在现代工业中有着广泛的应用前景。
荧光增白剂在涂料(油漆)中的应用与配方
荧光增白剂在涂料(油漆)中的应用与配方涂料旧称油漆或漆,因中国早期的商品涂料是用植物油脂熬炼而成,习惯上都称为油漆。
涂料是一种供涂布用的高分子材料,经采用不同的涂装工艺将涂料涂布在物体的表面以后,能形成坚韧而连续的薄膜附在物体的表面。
为尊重习惯本节没有将油漆、漆统一称为涂料。
荧光增白剂在油漆中的作用概括起来荧光增白剂在油漆中的作用是提高产品的白度或鲜艳度,改善产品的外观和使用性能。
随着人们生活水平的提高和科学技术的进步,油漆,如白色氨基烘漆、聚氨酯磁漆、醇酸磁漆等的作用已经不再是简单的保护被漆物体的表面,同时还具有美化漆物表面,给人以美感的作用。
很多透明或白色油漆有一种固有的黄色色调,过去在制造油漆的过程中,为了获得白色或淡色外观,尽量选择浅色透明基质和稳定而且白度高的白色颜料,除此之外,在白色漆中通常还加入一定量的蓝色颜料,即所谓的“上蓝”,利用蓝色和油漆黄色的互补作用来增加油漆的白度,但这种白色的亮度不高,有点灰暗。
荧光增白剂作为一种荧光染料已广泛地应用在白色或淡色的油读中,利用荧光增白剂可吸收紫外光而发射蓝紫色荧光,从而与漆膜表面的黄光混合而变为白色光,使漆膜表面趋于全反射,在人的视觉上白色油漆看起来更加洁白、亮丽;浅色油漆看起来更加艳丽夺目,极大地改善了产品的外观。
荧光增白剂在油漆中的另一个用途也是利用其可吸收紫外光而发射蓝紫色荧光的作用,在提高白色油漆白度或浅色油漆鲜艳度的同时,减少紫外线对油漆中颜料的损害,提高油漆的耐光性,延长油漆在室外及日光环境下的使用寿命二常用荧光增白剂的类型和品种由于油漆是由矿物颜料(如铅白、锌白)和干性油、树脂等制成的涂料,所以要求用于油漆中的荧光增白剂与其有良好的相容性,不溶于水,耐高温,具有一定的耐酸、碱性,有良好的耐气候牢度性能等,这些要求与第二篇第三章中塑料用荧光增白剂应具备的性质相似,可以参考。
用于非水溶性油漆的荧光增白剂大都是不溶于水的非离子分散型产品。

荧光增白剂在造纸行业中的应用
荧光增白剂在造纸行业中的应用摘要：介绍了荧光增白剂的增白原理和荧光增白剂的种类，介绍了荧光增白剂在纸浆、浆料、涂布工艺中的应用及影响增白效果的因素。
针对这些影响因素,提出了相应的解决方法。
关键词：荧光增明白剂；造纸；影响因素上世纪20年代，一种可以发射荧光的化合物被发现，它就是荧光增白剂。
因为它可以发射荧光从而达到提高纸张的白度以及各种纺织品的亮度，以此从30年代末开始正式在荧光增白剂行业得各行到广泛的应用，尤其是造纸行业，已经成为一种不可或缺且用量最大的白色染料。
1荧光增白剂的增白原理该荧光增白剂不仅具有双共轭双键，而且具有特殊结构的无色染料，光洁度好。
当它能吸收太阳光中的紫外线，激活分子，回到基态的时，紫外线的能量就会部分消失，消失的部分变转化为可见光，反射光为波长420-500nm的蓝紫色光，使纸上的反射光总量增加，抵消了黄光反射过大而引起的纸张纤维的黄感，从而提高纸张的白度。
随着入射光源的变化，荧光增白剂的效果就会发生变化，如果紫外线吸收的过多，效果会更加显著，如果在没有紫外线或者紫外线含量很低，就不会有美白效果或者美白效果不明显。
由于荧光增白剂的种类繁多，所以其荧光色光也不同，主要取决于紫外吸收波长范围，波长在335nm以下，荧光红是色，波长365nm以上的，荧光是绿色，这基本取决于分子取代基的性质。
[1]2荧光增白剂的种类荧光增白剂由于其化学结构的不同，有很多种，在造纸、纺织、洗涤用品和塑料等领域得到广泛的应用，主要分为五大类：：①二苯乙烯型；②香豆素型;③吡唑啉型;④联苯类;⑤萘二甲酰亚胺型等[2]，本文主要介绍在造纸行业经常使用的三种类型：2.1二苯乙烯型二苯乙烯型是造纸行业应用最广泛的荧光增白剂，主要有双三嗪氨基二苯乙烯类、单/双三唑二苯乙烯类、二苯乙烯基苯类和二苯乙烯苯并唑类等。
根据分子内磺酸根的含量，将双三嗪二苯乙烯类增白剂分成三种类型，即二磺酸、四磺酸、六磺酸。
荧光增白剂VBL，被称为4，4-双-(4-羟乙氨基-2-苯胺基-1，3，5-三嗪-2-氨基)二苯乙烯-2，2-二磺酸钠]型增白剂，是最常用的增白剂，也是造纸中最重要的类型，产量最大，占80%以上。

The whiteness of coating and natural painting could also be greatly improved by SP-KCB.Safety and stock:Keeping in stock as ordinary chemicals. Wear protective goggles and gloves while applying.A void direct contact with skin and eyes. Soap clean if skin contaminated.Packing:25kg / fiber drum with PE linerOptical Brightener Odyssey OB-1 （荧光增白剂OB-1）Optical brighteners are added to many materials to reduce yellowing, improve whiteness, and to enhance the brightness of a product. Odyssey OB-1 is used widely in the plastic market. Because of its excellent brightening ability,good thermal stability,and compatibility with many polymers. Typical PropertiesChemical name: 2,2-(1,2-Ethenediyldi-4, 1-phenylene) bisbenzoxazoleMolecular weight: 414.4CAS No.: 1533-45-5C.I.: 393Specifications:Ash %Empirical FormulaMelting Point(DTA),CAppearanceOdorV olatile Content %Assay %Particle Size0.3maxC28H18N2O2353-359Y ellowish Green PowderFree of odor0.3max99min200 meshesEffect of Optical Brighteners on the Whiteness of PolymersOptical brighteners function by absorbing ultraviolet radiation and remitting blue light. The emitted blue light will reduce the yellow color of a polymer. In the presence of a whitening agent, such as TiO2, the use of Odyssey OB-1 will produce a brilliant white o r “white than white” appearance.Two primary factors affect the whiteness/yellowness of a formulation. They are the color of the base polymer and the level of brightener added. If no whitening agent, such as TiO2, is used, the level of Odyssey OB-1 required will likely be lower than when a whitening agent is preset. This level might be as little as 25-50 ppm. In determining the optimum concentration of brightener, the effect of any other UV-absorbing materials in the plastic should be considered. It is important that users perform sufficient evaluations to determine the optimum level of Odyssey OB-1 for their specific end uses.Methods of AdditionTo be effective, an optical brightener must dissolve in the polymer to which it is added. Since the typical addition levels for Odyssey OB-1 in the range of 100-400 ppm, the use of a concentrate, or masterbatch, is recommended. Concentrates are containing 1%-10% by weight of Odyssey OB-1 typical.The concentrate can be produced on an extruder using normal processing conditions for the polymer, including drying if necessary. The concentrate is then let down to typical use levels in the final formulation. Plastics compounding equipment is normally adequate for producing Odyssey OB-1 brightener formulations. The key requirement is to thoroughly disperse the brightener so that it will dissolve uniformly throughout the molten polymer. This is usually achieved most readily with a concentrate.Improving Whiteness of Recycled PolymerThe business of processing post consumer plastics and waste polymer continue to grow. These materials can be recycled into a variety of useful products, from plastic lumber to synthetic fiber. Polyester bottle polymer, polyester plastic waste, and waste fiber polymer can be recycled into polyester fiber that can be used in carpets, filling and insulation material, nonwovens, and apparel. One of the shortcomings of processing these materials is the uncertainty of the color of the source material.By using optical brighteners, the value of the recycled materials can be significantly enhanced by providing a more uniform white. Odyssey OB-1 will greatly improve the whiteness, Normal fiber applications require only 200-300 ppm in new polymer, but recycled material may require as much as 300-450 ppm. Optical brighteners are very effective in improving the appearance of the polymer or fiber. Off-class or second-quality nylon polymer can also be improved in the same way.Food Industry ApplicableOdyssey OB-1 complies with regulations for indirect food additives. Odyssey OB-1 is restricted to use as an optical brightener for all polymers at a level not to exceed 0.025% by weight of polymer and at the temperatures not to exceed 135"C(275"F).Packing:25kg / fiber drum with PE linerHomepage Chinese V ersionWelcome you to visit the website of Beijing Odyssey Chemicals Co.,Ltd.© Beijing Odyssey Chemicals Co.,Ltd.
