What should be paid attention to when using fluorescent brightener

White plastic products in many colors of plastic has been dominant, we usually see white plastic in the production process, in order to achieve bright white effect, often add a small amount of fluorescent whitening agent to improve product quality. However, some manufacturers will tell us that the same problem is that the products made by themselves with fluorescent whitening agents have not achieved an ideal whitening effect, while the effect of others is very obvious. What is the reason? Today, Shanghai enmai editor will solve this problem for you.

 

1. The type of fluorescent brightener selected is not suitable

 

At present, there are many types of fluorescent whitening agents used in plastics. Different types of fluorescent whitening agents have different appearance, melting point, heat resistance, compatibility and weather resistance. Once the plastic manufacturers do not choose the right fluorescent whitening agent, it is difficult for the whitening agent to give full play to its effect.

 

Another important point is to ensure the quality of fluorescent whitening agent. After all, the content of whitening agent in the market is uneven, and the phenomenon of shoddy is emerging one after another.

 

2. The amount of fluorescent brightener is not suitable

 

Any good product addition is not the more the better, if the fluorescent whitening agent exceeds the recommended dosage, not only can not play a whitening effect, but will appear yellowing, or whitening agent precipitation.

 

However, if the amount is too small, it can not achieve the desired whitening effect, so we need to test the amount in the early stage to find a suitable amount.
