PVC gusset plate ceiling material is made by mixing, calendering, vacuum plastic absorption and other processes, using polyvinylchloride resin as the base material, adding a certain amount of anti-aging agent, modifier and other additives. During the production process of buckle plate manufacturers, the cost of using new materials is too high and the profit margin is too limited, so many manufacturers will add a certain proportion of recycled materials during the production process. However, the products produced in this way will experience a decrease in whiteness, brightness, glossiness, and weather resistance. In the sales process of PVC gussets, customers often have high requirements for the whiteness, gloss, and color difference at the joints of the gussets.

How to choose Optical brightener for PCV gusset
PVC gusset plate manufacturers usually use KB, OB-1 and other types of Optical brightener, which can achieve good whitening effect. However, different products, different production processes and production environments have a certain impact on the selection of Optical brightener, which requires technology to select the one with high cost performance according to the specific production situation. In addition to the model to be added, targeted recommendations should be made, and the amount to be added should also be paid attention to. Too much or too little can not achieve the desired effect.
