â—† The moisture in the plastic raw material can be taken away to eliminate the generation of bubbles, so that the product can achieve the desired mechanical, electrical, dimensional stability and appearance.
â—† Prevent the generation of defective products and return loss, and reduce the generation of waste.
â—† Because the dehumidifying dryer uses very dry air for dehumidification, it can shorten the drying time and save man-hours.
â—† The air line of the dehumidifying dryer adopts a closed circulation system and is equipped with a filter, so it is not affected by the external weather, and can prevent dust from causing pollution in the factory and improve the working environment.
A good drying efficiency determinant is: Drying Temperature, Residence Time, Air Flow, and Dew Point. These four factors are interlocking and any one condition changes. Will affect the drying effect.
◆ Drying temperature refers to the temperature of the air entering the drying drum. Each raw material has certain restrictions on the temperature during drying due to its physical properties such as molecular structure, specific gravity, specific heat and water content. When the temperature is too high, the raw materials will be used. Some of the additives in the volatilization are metamorphosed or agglomerated, too low, and some crystalline raw materials can not reach the required drying conditions, such as: PC / 120 ° C, ABS / 80 ~ 95 ° C. In addition, insulation insulation is required in the selection of dry barrels to avoid leakage of drying temperature, resulting in insufficient drying temperature or waste of energy.
â—† Drying time refers to the pre-drying time before the raw material is formed. If the drying time is too long, the raw material will deteriorate or agglomerate or waste energy. If the drying time is too short, the water content will be too high. For example: PC / 3-4 hours, ABS / 3-4 hours.
â—† Air volume is the only medium to take away the moisture in the raw materials. The amount of air volume will affect the dehumidification effect. Too much air will cause the return air temperature to be too high, causing overheating and affecting the stability of the dew point. If the air volume is too small, the moisture in the raw material cannot be completely taken away. The air volume also represents the dehumidification capacity of the dehumidifying dryer.
◆ Dew point temperature refers to the temperature at which the gas is cooled to condense the moisture contained in the water, which is a unit for measuring the degree of drying (wet) of the gas. The less moisture in the gas, the lower the dew point temperature. A good dehumidifying dryer should have a dew point of -40 ° C dew point.
