Lámina de PVC de plástico rígido sólidose suele realizar superponiendo y calentando la lámina de PVC enrollada. La lámina de PVC de plástico rígido sólido se divide en 3 etapas de calentamiento, 1 etapa de ajuste y 1 etapa de enfriamiento.
1. Etapa de calentamiento a baja temperatura
2. Etapa de calentamiento de temperatura media
3. Etapa de calentamiento de alta temperatura
4. Detener la etapa de ajuste de calefacción
5. Etapa de enfriamiento
PVC rigid board is usually made by superposing and heating the rolled PVC sheet. According to needs, this solid rigid plastic PVC sheet can be flexibly made into various thicknesses. As PVC is a thermally unstable resin, it will decompose to release HCl and form a polyene structure. If processed at high temperature for a long time, it will seriously affect the performance of the product. However, PVC is also a poor heat conductor and slow heat transfer. To prepare products with good performance, the heating time is difficult to control. If the heating time is not enough, the inside of the board is easy to layer; if the heating time is too long, it will not only reduce the production efficiency, What's more serious is that PVC will decompose rapidly at high temperature for a long time, which will affect the performance of the product.
