Moist plastic particles will reduce the strength and toughness. For precision parts (transparent products, opaque), it is difficult to find substantial defects with the naked eye. It is the result of water decomposition due to insufficient drying, and it is always the main reason for the production of substandard products. The difference between plastic dehumidification dryer and low drop point dehumidifying dryer!
Let us first talk about the low-point dehumidification dryer. The low-fall point dehumidifying dryer uses electric heating and hot air to dry the materials in the space at a high temperature, and the purpose is to evaporate the water in the material. The incoming air heated by the electric heating is the air in the environment. In dry weather and humid weather, the moisture content in the air is different. Therefore, when the weather is wet, incomplete drying of the material will occur. Because electric heating must first heat the incoming air, but the incoming air contains high moisture, how can the material be dried thoroughly? (Mainly reflected in materials with high moisture absorption rate, such as nylon).
For this reason, the low-drop point dehumidifyting dryer came into being. In view of the above situation, firstly, the ambient air is drawn in to remove the moisture in the air at a low dew point, and then relatively dry air is used to heat the material into the dryer to dry the material. Therefore, the difference between these two dryers is that the moisture content of the inlet air used for drying is different. One has processed the inlet air moisture, and the other has not processed the inlet air moisture.
