In industry, the amount of Fluorescent Whitening Agent Ob is very large, but there are many ink manufacturers using Fluorescent Whitening Agent OB but do not know what kind of good. I will introduce to you. The fluorescent Whitening Agent OB can be dissolved in an organic solvent, but the solubility is relatively low. When many ink manufacturers dissolve, it is considered that the product of the fluorescent whitening agent OB having good solubility is high in purity, which is also a mistake. Confirmed. The amount of good fluorescent whitening agent OB used in the ink is also very small, as long as it is added to 200 to 300 grams per ton, the high addition amount will affect the color of the product, so that the fluorescent whitening agent OB cannot be completely dissolved. The effect of using a fluorescent whitening agent OB is also good, and it is also recognized by many ink manufacturers, that is, plastic gang.
Generally, in the production process of good water-based ink coatings, the Fluorescent Brightener OB is used. Fluorescent Brightener OB not only increases the whiteness of the ink, but also increases the brightness of the ink. Fluorescent brightener OB-1 improves the grade of the product.
Therefore, it is very important to choose the Optical Brightener. Jinan Forever Chemical has always been adhering to the tenet of [ integrity management, cooperation and win-win", providing each customer with the highest quality optical brightener. And the appearance of color personalization needs.
