Dehumidification dryer

Classification:


The main reason for the poor quality such as bubbles, silver lines, cracks, flow marks and poor transparency is that the plastic has not been fully dried before molding. For the raw materials with strong hygroscopicity such as PA and PCPBTPETNYLON, the traditional dryer cannot completely dry it due to the moisture penetrating into the plastic granules. Practice has proved that reducing the dew point of the drying air to below -40 ℃ and controlling the heat to blow it over the surface of the wet plastic particles can reduce the moisture content to below 0.02 before molding. The honeycomb dehumidifier is the use of honeycomb wheel in the closed circulation system will fully dehumidify the air, and quickly the moisture in the plastic particles completely separated to achieve the effect of dehumidification and drying.

Working principle

Bubbles, silver lines, cracks, flow marks, poor transparency and other poor quality is the main reason is that the plastic has not been fully dried before molding, engineering plastics such as PA,PCPBTPETNYLON and other moisture absorption of strong raw materials, due to moisture penetration into the plastic particles, the traditional dryer is unable to make it completely dry.

Practice has proved that reducing the dew point of the drying air to below -40 ℃ and controlling the heat to blow it over the surface of the wet plastic particles can reduce the moisture content to below 0.02 before molding. The honeycomb dehumidifier is the use of honeycomb wheel in the closed circulation system will fully dehumidify the air, and quickly the moisture in the plastic particles completely separated to achieve the effect of dehumidification and drying.
