When it comes to UPVC Profile, many people don't know it very well, but it is very common in our lives, but we usually don't pay much attention to it. UPVC Profile is mainly used for sliding and sliding doors and windows, guardrails, pipes and ceiling materials. Most of them are white. White is very clean and bright, so it is very popular. But we know that, like this white UPVC Profile, it is exposed to ultraviolet light. Yellowing will appear after long exposure, which will affect the appearance. Nowadays, people pay more and more attention to the appearance of products. The yellowing of products and after-sales problems also make manufacturers more headaches. In fact, LUMEI Profile manufacturers tell everyone that there is no way to solve this problem. You only need to add a chemical additive in the production process. ——UPVC Profile fluorescent whitening agent can be solved.
However, there are many types of fluorescent whitening agents on the market, which one is suitable for UPVC Profile? This problem can be solved by adding UPVC Profile optical brightener FP-127 in the production process. The appearance of the fluorescent brightener FP-127 is light yellow crystalline powder, the melting point is 219-221℃, and the color light is blue-violet light. It is suitable for all kinds of PVC products. Only a small amount is needed, and the whiteness and brightness are greatly improved.
Or you can use the fluorescent whitening agent OB-1, in fact, it is mainly because the substrate contains a colored impurity, which will absorb blue or blue-violet visible light. The reason why the fluorescent whitening agent can brighten the fifth yellow light is because the fluorescent whitening agent can absorb ultraviolet light after being adsorbed on the substrate, and can emit blue or blue-violet visible light at the same time. The light emitted by it compensates for the light absorbed by the substrate. It is known from the principles of physics that the two complementary colors of light are superimposed to form white light, so the perception of the human eye is that the whiteness and vividness of the object have increased , Which means that the UPVC Profile has been whitened.
