塑料板材运用荧光增白剂的留意事项
Notes on the Application of Fluorescent Whitening Agent in Plastic Plates
塑料板材用荧光增白剂应该留意什么那些?塑料板材用是荧光增白剂大多都是传统的OB-1,但这种增白剂的耐候性欠好,很容易发生黄变
What should we pay attention to when using fluorescent brighteners for plastic sheets? Most of the fluorescent brighteners used for plastic sheets are traditional OB-1, but the weather resistance of this brightener is not good and it is easy to yellowing.
1.留意荧光增白剂的添加量:
1. Note the amount of fluorescent whitening agent added:
产品泛黄的原因与恰当的添加量有很大的联系,主张在专家的指导下进行添加,一般荧光增白剂的添加量是在每吨塑料100-500克之间。
The reason for yellowing of products is closely related to the appropriate amount of additions. It is advocated to add fluorescent brighteners under the guidance of experts. The amount of additions of fluorescent brighteners is between 100 and 500 grams per ton of plastics.

2.运用办法和工艺:
2. Application methods and processes:
荧光增白剂的运用一定要适用出产的工艺,如果添加的办法或许办法不正确的话,也会其时荧光增白剂的作用不明显。一定要留意添加的工艺,充分的松散到产品中即可。
The application of fluorescent whitening agent must be suitable for the production process. If the method of adding fluorescent whitening agent is incorrect, the effect of fluorescent whitening agent will not be obvious at that time. Be sure to pay attention to the process of adding, fully loose to the product can be.
3.如果以上办法作用仍是不志向,可以用一些介体,提前把荧光增白剂增白剂溶解,这样可以进步松散功能,
3. If the above method is still not ambitious, some intermediates can be used to dissolve the fluorescent whitening agent in advance, so as to improve loose function.
以上办法仍是不能解决那就说明现在用的质料配方有一定的问题,或许是运用的办法还存在的问题。
The above methods are still not able to solve the problem, that is to say, there are some problems in the material formula used now, perhaps there are still problems in the method used.
