Method/step
1. Firstly, a certain proportion of fluorescent whitening agent is dissolved in multifunctional plasticizer. Here, we use 100 kilograms of new base materials, add about 20 grams of fluorescent whitening agent and about 300 grams of plasticizer, which is based on the proportion of old base materials(recycle materials). The more old base materials, the greater the added amount of fluorescent whitening agent .
2. After the whitening agent and plasticizer are fully fused, they are put into a stirrer and stirred evenly with the materials.
3. Feeding can be carried out in various ways, such as air pumping and screw feeding.
4. Look at the effect and make a comparison.
· Matters need attention:
· The amount of whitening additive must be controlled well, and it can't be added too much. The general range is 100-500g/ton.
· The whitening agent and plasticizer must be stirred evenly.
