How to solve the problem of ABS raw materials agglomerating and not being discharged in the 78°C baking barrel?
In the plastic processing process, drying ABS raw materials is a key link to ensure product quality. However, many factories often encounter a headache when using baking barrels to dry ABS: when the temperature is set at 78°C, the raw materials always clump and cannot be discharged smoothly. This not only affects production efficiency, but may also cause machine shutdowns and increase maintenance and management costs. So, what causes ABS raw materials to frequently agglomerate at 78°C? How can we solve this problem?
- Improper temperature setting
First, the drying temperature of 78°C may be too low for ABS raw materials. Generally, the drying temperature of ABS should be between 80°C and 90°C to ensure that the moisture in the raw materials is completely removed. If the temperature is lower than this range, the surface of the raw material may appear dry, but the internal moisture is not completely evaporated, causing the raw material particles to stick to each other and eventually form agglomerates. Therefore, appropriately raising the drying temperature to above 80°C may be the key to solving the problem. - Too long drying time
Even if the drying temperature is moderate, too long drying time will cause the surface of ABS raw materials to melt slightly, thus causing agglomeration. ABS has a certain degree of thermal sensitivity, and long-term high-temperature drying can easily soften the surface and cause particles to stick together. Therefore, it is recommended to control the drying time to 2-4 hours and adjust it in time according to the production rhythm. - Insufficient control of environmental humidity
ABS raw materials are very easy to absorb moisture. If the raw materials have absorbed too much air moisture before drying, low-temperature drying may not be able to effectively remove this moisture, causing the raw materials to become sticky and agglomerated. To avoid this situation, the factory should use a three-in-one dehumidifying dryer. This type of equipment can control the humidity in the baking barrel within a reasonable range through an independent dehumidification function, effectively preventing the raw materials from absorbing moisture. - Equipment wind speed and airflow distribution problems
During the drying process, the airflow distribution and wind speed in the equipment are also important factors affecting the drying effect. If the wind speed is too low or the airflow distribution is uneven, the heat in the baking barrel cannot be evenly transferred to the entire raw material area, resulting in local softening and agglomeration of raw materials. It is recommended to regularly check the air duct design of the equipment to ensure good hot air circulation. - Problems with the raw materials themselves
Batch differences, improper storage conditions, or the use of additives in ABS raw materials may also cause agglomeration during the drying process. Therefore, it is recommended to check the storage environment of the raw materials before drying and try to avoid exposing the raw materials to a humid environment. At the same time, choose a high-quality ABS raw material supplier to ensure the stability of the raw materials.
Solution: Advantages of three-in-one dehumidification dryer
For the problem that ABS raw materials are prone to agglomeration, the three-in-one dehumidification dryer is an ideal solution. This equipment integrates dehumidification, drying, and feeding. By accurately controlling temperature and humidity, it ensures that ABS raw materials can be dried evenly and thoroughly to avoid the occurrence of agglomeration problems. Not only that, its intelligent control system can adjust drying parameters in real time, greatly improve production efficiency, and reduce downtime.
In short, by reasonably adjusting the drying temperature, time, humidity control, and equipment optimization, the problem of agglomeration of ABS raw materials at 78°C can be effectively solved to ensure the efficient operation of the production line. If you encounter similar problems in the plastic processing process, you might as well try the three-in-one dehumidification dryer, which may be the best help for you to improve production efficiency and reduce downtime!
