PVC foaming regulator can help polyvinyl chloride foamed products to provide good regulation effect. By adding high molecular weight polymer, it can help PVC quickly plasticize, and it can also increase the strength of its melt to achieve uniform foaming. How to improve the quality ?
1. There are many ways to improve the quality of PVC foaming regulators. The main factor is to increase the melt strength of PVC , so the reasonable method is to increase the additives to increase the melt strength and reduce the processing temperature;
2. Polyvinyl chloride belongs to amorphous data, and the melt strength decreases with the increase of melt temperature; on the contrary, the melt strength decreases with the decrease of melt temperature, but the cooling effect is limited to auxiliary effects. ACR type treatment agent has the function of improving the melt strength, among which PVC foaming regulator is effective. As the content of foaming regulator increases, the melt strength increases;
3. Generally, only the screw has sufficient dispersing ability, and increasing the PVC foaming regulator is more effective in improving the melt strength.
The above is an introduction to the methods to improve the quality of PVC foaming adjustments. Generally speaking, we have to learn to increase the strength of the melt and reduce its processing temperature during the construction process. After understanding this method, you can make improvements in production and observe whether it can improve product quality. At the same time, you must also pay attention to reasonable innovation and improvement in combination with the actual situation.
