教你荧光增白剂和钛白粉的区别
Teach you the difference between fluorescent whitener and titanium dioxide
荧光增白剂可以增白,钛白粉也可以增白剂,那麼,荧光增白剂和钛白粉的增白原理有什麼区别。
Fluorescent whitening agent can whiten, titanium dioxide can also whitening agent, then, what is the difference between fluorescent whitening agent and titanium dioxide whitening principle?
1.荧光增白剂是一种能提高塑料、纤维织物和纸张等白度的无机化合物。又称光学增白剂、荧光增白剂。织物等常常由于含有色杂质而呈黄色,过去都采用化学漂白的方法中止脱色,如今采用在制品中添加荧光增白剂的办法。荧光增白剂的作用是把制品吸收的不可见的紫外线辐射转变成紫蓝色的荧光辐射,与原有的黄光辐射互爲补色成爲白光,提高产品在日光下的白度。
1. Fluorescent whitening agent is an inorganic compound which can improve the whiteness of plastics, fibre fabrics and paper. Also known as optical whitening agent, fluorescent whitening agent. Fabrics are often yellow due to the presence of colored impurities. In the past, chemical bleaching was used to stop bleaching. Today, fluorescent brighteners are added to the products. The function of fluorescent whitening agent is to change the invisible ultraviolet radiation absorbed by the product into violet-blue fluorescent radiation, and complement the original yellow radiation to white light, so as to improve the brightness of the product in sunlight.
荧光增白剂已经普遍运用在纺织、造纸、洗衣粉、肥皂、橡胶、塑料、颜料和油漆等方面。荧光增白剂普通分爲两类,一类是水溶性的增白剂,另一类爲水不溶性增白剂。前类可用于纸张,涂料,洗衣粉,棉织物的增白剂,另一类可用于化纤,塑料的增白。
Fluorescent whitening agents have been widely used in textiles, papermaking, laundry powder, soap, rubber, plastics, pigments and paints. Fluorescent whitening agents are generally divided into two categories, one is water-soluble whitening agents, the other is water-insoluble whitening agents. The former can be used as whitening agent for paper, paint, detergent and cotton fabrics, and the other can be used for whitening of chemical fibers and plastics.

2.钛白粉是一种非常好的白色颜料,又具有补强、防老化、填充作用,普遍用于橡胶制品,塑料管材型材。在白色和黑色橡胶制品中参与钛白粉,在日光照射下,耐日晒,不开裂、不变色,伸展率大及耐酸碱。橡胶用钛白粉,主要用于汽车轮胎以及胶鞋、橡胶地板、手套、运动器材等,普通以锐钛型爲主。
2. Titanium dioxide is a very good white pigment. It also has the function of reinforcing, anti-aging and filling. It is widely used in rubber products and plastic pipe profiles. Participate in titanium dioxide in white and black rubber products. Under sunlight, it is sunproof, non-cracking, no color change, high elongation and acid and alkali resistance. Titanium dioxide for rubber is mainly used in automobile tires, rubber shoes, rubber flooring, gloves, sports equipment, etc. Anatase is the main type.
其次钛白粉也是一种非常好的光屏蔽剂。金红石型(R型)钛白粉相对密度4.26,折光率2.72,能反射或折射大部分可见光,并能完全吸收波长小于410nm的紫外线,耐热性、耐候性好,屏蔽紫外线的作用强,是提高型材耐候性的重要原料之一。由于高分子材料中参与钛白粉会使粘度上升,活动性降低,扭矩增大构成加工困难,普通参与5份左右即可,但是普通只添加钛白粉白度达不到要求,因此吉灵化工都会建议客户添加大批荧光增白剂。
Secondly, titanium dioxide is also a very good light shielding agent. The relative density of rutile titanium dioxide (R type) is 4.26, and its refractive index is 2.72. It can reflect or refract most visible light and absorb ultraviolet rays with wavelength less than 410 nm. It has good heat resistance, weather resistance and strong shielding effect. It is one of the important raw materials to improve the weather resistance of profiles. Because the participation of titanium dioxide in macromolecule materials will increase the viscosity, decrease the activity and increase the torque, which makes it difficult to process. It is only possible to take part in about 5 parts. But the whiteness of titanium dioxide can not meet the requirements. Therefore, Jilin Chemical Company will recommend that customers add a large number of fluorescent brighteners.

3. The difference between fluorescent whitening agent and titanium dioxide
部分作用不同:增白剂是单一的增白、增艳;钛白粉是颜料,除增白以外,还起到填充作用;运用量不同:荧光增白剂的用量在 0.02%~0.05%之间;钛白粉的用量是2%左右;增白原理不同:钛白粉是颜料,可以使底色增白,常用来打底;增白剂是经过吸收紫外线发出荧光使产品更白更亮;价钱不同:荧光增白剂的价钱是几十万一吨,而钛白粉的价钱相对而言廉价很多,只需几万一吨。
Part of the effect is different: whitening agent is a single whitening, brightening; titanium dioxide is a pigment, in addition to whitening, it also plays a filling role; the amount of use is different: the amount of fluorescent whitening agent is between 0.02% and 0.05%; the amount of titanium dioxide is about 2%; the principle of whitening is different: titanium dioxide is a pigment, which can make the background whitening, often used for priming; whitening agent is fluorescent by absorbing ultraviolet light. The product is whiter and brighter; the price is different: the price of fluorescent brightener is hundreds of thousands of tons, while the price of titanium dioxide is much cheaper, only tens of thousands of tons.
