荧光增白剂ob与ob-1的不同你知道吗?


网址:http://www.scvc8.com  时间:2019-06-19 16:10:10

  荧光增白剂ob和ob-1,这两个看起来像兄弟。当我第一次听说荧光增白剂ob和ob-1时,我想当然地认为ob-1是ob的复合产物,ob的纯度降低到了ob-1。后来因为这种错误的认识也闹了不少笑话。那么ob和ob-1有什么区别呢?哪些产品应该使用ob?哪种产品更适合使用ob-1?
  Fluorescent whiteners OB and ob-1, which look like brothers. When I first heard about fluorescent brighteners OB and ob-1, I took it for granted that OB-1 was a compound product of ob, and the purity of OB was reduced to ob-1. Later, many jokes were made because of this wrong understanding. So what's the difference between OB and ob-1? Which products should use ob? Which products are more suitable for using ob-1?
  Ob和Ob -1是完全不同的化学物质
  Ob and Ob-1 are completely different chemicals
  荧光增白剂Ob的物理参数:
  Physical parameters of fluorescent whitening agent Ob:
  化学名称:2,5-双(5-叔丁基-2-苯并恶唑基)噻吩
  Chemical name: 2,5-Bis (5-tert-butyl-2-benzoxazolyl) thiophene
  分子式:C26H26N2O2S
  Molecular formula: C26H26N2O2S
  分子量:430
  Molecular weight: 430
  包括:99.5%
  Including: 99.5%
  灰:0.5%
  Gray: 0.5%
  外观:淡黄色结晶粉末
  Appearance: Light yellow crystalline powder
  熔点:201-203℃
  Melting point: 201-203 C
  溶解性:溶于有机溶剂
  Solubility: Soluble in organic solvents
  荧光增白剂ob-1的物理参数:
  Physical parameters of fluorescent whitening agent ob-1:
  化学名称:4,4 '-二(2-苯并恶唑基)二芘
  Chemical name: 4,4'-bis (2-benzoxazolyl) dipyrene
  分子式:C28H18N2O2
  Molecular formula: C28H18N2O2
  分子量:414.45
  Molecular weight: 414.45
  包括:99.5%
  Including: 99.5%
  灰:0.5%
  Gray: 0.5%
  外观:黄色或黄绿色结晶粉末
  Appearance: Yellow or yellowish green crystalline powder
  熔点:355-360℃
  Melting Point: 355-360 C
  溶解性:溶于有机溶剂
  Solubility: Soluble in organic solvents
  荧光增白剂ob的分子式为C26H26N2O2S, ob-1的分子式为C28H18N2O2。从上图中,我们可以清楚地看到这两种化学物质是完全不同的。这一点,千万不要犯和小编一样的错误哦!
  The molecular formula of fluorescent brightener ob is C26H26N2O2S and that of OB-1 is C28H18N2O2. From the above picture, we can clearly see that the two chemicals are completely different. Don't make the same mistake as the minor edition.
  哪些产品使用荧光增白剂ob,哪些产品使用ob-1更合适?
  Which products use fluorescent whitening agent ob, which products use OB-1 more appropriate?
  当然是两种不同的化学物质,但是从名字上,你可以猜到这两种物质有很多相似之处。例如,荧光增白剂Ob和Ob -1的应用范围很广,大多数塑料增白剂Ob和Ob -1可以通用,增白增白效果明显。有什么不同呢?
荧光增白剂OB-1
  Of course, there are two different chemicals, but you can guess from the name that there are many similarities between the two substances. For example, fluorescent whitening agents Ob and Ob-1 have a wide range of applications. Most plastics whitening agents Ob and Ob-1 can be used in general, and the whitening effect is obvious. What's the difference?
  1. 熔点:ob-1 > ob
  1. Melting point: OB-1 > ob
  由于荧光增白剂ob的熔点是200度,和ob-1的熔点高达360度,它是确定荧光增白剂ob不能用于高温塑料制品,如空调房和一些厨具。所以,如果你的产品是在高温下加工的,荧光增白剂ob-1是你的首选。
  Because the melting point of Fluorescent Whitening Agent OB is 200 degrees and that of OB-1 is 360 degrees, it is determined that fluorescent whitening agent ob can not be used in high temperature plastic products, such as air conditioning rooms and some kitchen utensils. So if your product is processed at high temperature, fluorescent whitening agent OB-1 is your first choice.
  2. 分散性和稳定性:ob>ob-1
  2. Dispersion and stability: ob>ob-1
  在这里,首先要澄清的是,良好的色散性意味着该产品的水溶性较平均,如涂料油墨,对荧光增白剂的色散要求较高;稳定性好是指产品后期不易发作迁移发黄的现象,例如一些劣质鞋底,刚买回来的分白干净,但过一会儿头发发黄变色,这是为了澄清荧光增白剂稳定性差。
  Here, first of all, it should be clarified that good dispersion means that the product has average water solubility, such as paint ink, which requires higher dispersion of fluorescent whitening agent; good stability means that the product is not easy to migrate and yellowing in the later stage, such as some poor soles, which have just been purchased white and clean, but after a while the hair yellows, which is to clarify the stability of fluorescent whitening agent. Qualitative difference.
  当然,我并不是说的分散与稳定荧光增白剂ob-1不好,但略低于ob。由于这种区别,简达化学不建议使用的荧光增白剂ob-1油墨涂料和软塑料,ob相对分散和耐气候性会更好,不容易显示黄色的迁移。
  Of course, I am not saying that the dispersing and stabilizing fluorescent whitening agent OB-1 is not good, but slightly lower than ob. Because of this difference, fluorescent brightener OB-1 ink coatings and soft plastics, which are not recommended by Simple Chemistry, are better dispersed and weather-resistant, and are not easy to show yellow migration.
  3.价格是ob和ob-1之间最大的差异
  3. Price is the biggest difference between OB and OB-1
  事实上,荧光增白剂ob和ob-1最大的区别在于价格。小编记得5年前,荧光增白ob和ob-1的价格差不多,但后来由于环保整改,ob提出问题的原始材料的供应,所以ob的价格飙升,ob ob-1贵两倍,据估计,它可能上升。由于价格差异较大,所以可以使用荧光增白剂ob-1客户,尽量选用ob-1,有特殊要求的客户,如高档油墨涂料和软塑料客户,建议仍使用ob。
  In fact, the biggest difference between fluorescent brighteners OB and OB-1 is the price. Five years ago, the price of fluorescent whitening ob was about the same as that of ob-1, but then the price of OB soared twice as high as that of OB-1 because of environmental protection and the supply of raw materials that OB raised questions about. It is estimated that the price of OB-1 may rise. Because of the large price difference, we can use fluorescent whitening agent OB-1 customers, try to choose OB-1 customers, customers with special requirements, such as high-grade ink coatings and soft plastic customers, it is recommended to use ob.
