There are many ways to improve the quality of PVC foaming regulators. The main factor is to increase the melt strength of PVC. Therefore, a reasonable method is to add additives to improve melt strength and reduce processing temperature.
PVC foaming regulators can help PVC foaming products provide good regulatory effects. By adding high molecular weight polymers, PVC can be quickly plasticized and its melt strength can be improved, achieving a uniform foaming effect. So, for this product, quality issues cannot be ignored. We should pay attention to its quality requirements. So, how to improve its quality? Let’s take a look together
PVC foaming regulator is a polymer material. There are many ways to improve the quality of PVC foaming regulators. The main factor is to increase the melt strength of PVC. Therefore, a reasonable method is to add additives to improve melt strength and reduce processing temperature.
Polyvinyl chloride belongs to amorphous data, and the melt strength decreases with the increase of melt temperature. On the contrary, the strength of the melt decreases with the decrease of the melt temperature, but the cooling effect is limited to the auxiliary effect. ACR type processing agents have the effect of improving melt strength, among which PVC foaming regulators are effective. As the content of foaming regulators increases, the melt strength increases.
Generally, only the screw has sufficient dispersing ability, and adding PVC foaming regulators is more effective in improving the melt strength.
In the current situation, industry competition is intensifying, and many downstream customers, especially for foamed wood plastic products, often add a large amount of small pipe materials, plastic steel materials, etc. to the foamed PVC formula in order to improve their price competitive advantage. Secondary plasticized materials can greatly accelerate the overall material plasticization. Therefore, in order to achieve good foaming effect, we suggest that the temperature of the first and second zones of the material barrel be appropriately reduced, Alternatively, use a foaming regulator with slower plasticization and higher melt strength. This not only improves the foaming effect, but also saves some foaming agent, and the quality of PVC foam products will be better. Of course, choosing the right manufacturer is also of utmost importance.
The above is an introduction to methods for improving the quality of PVC foaming regulators. Generally speaking, we should learn to increase the strength of its melt and reduce its processing temperature during the construction process. After understanding this method, improvements can be made in production, observing whether product quality can be improved, and paying attention to combining reasonable innovation and improvement with oneself.
