What are the factors that affect drying effect of dryer?
The dry hot air transfers heat to the particles in the drying bin, removing moisture from the particles and then returning moisture to the dryer. Therefore, it is necessary to have the desired airflow to heat the resin to the drying temperature, and keep the temperature at a certain moment
In the air around the particles, the absorption of heat and the dispersion of water molecules to the surface of the particles require certain moments. Therefore, the resin supplier shall specify the time at which all the necessary drying of a material is dried at the proper temperature and dew point
Heat is the key to the synergy between boiling water molecules and hygroscopic polymers. When higher than a certain temperature, the attraction between water molecules and polymer chains will drop greatly, and water vapor will be taken away by dry air
In the dryer, the first is to remove the moist air so that it contains very little residual moisture. The air is then heated to decrease its relative humidity. At this point, the steam pressure of the dry air is low. After heating, the water molecules in the particles escape from the bond force and disperse into the air around the particles
