In the PET bottle blowing industry, every link of material processing will directly affect the quality of the final product. Especially for PET plastic particles, which are highly hygroscopic materials, if they are not properly dehumidified, a series of quality problems will occur during the heating and molding process, such as bubbles, increased brittleness, uneven color, etc. At this time, the plastic dehumidification dryer becomes an indispensable tool in the industry.
Why does PET need dehumidification?
PET materials easily absorb moisture in the air. When these particles with moisture melt at high temperatures, the moisture evaporates and forms bubbles, causing the bottle surface to be uneven or opaque, affecting the appearance quality. More seriously, moisture will trigger the hydrolysis reaction of PET, destroy its molecular structure, cause the bottle to become brittle, reduce durability, and affect its performance in practical applications.
The role of plastic dehumidification dryer
In order to solve these problems, PET bottle blowing production lines are usually equipped with dehumidification dryers to ensure that the raw materials are fully dried before entering the melting stage. Compared with traditional hot air drying, dehumidification dryers can more effectively remove moisture from PET by reducing air humidity. This not only improves the appearance of the bottle, but also improves its mechanical properties, ensuring the bottle’s impact resistance and toughness.
In addition, the plastic dehumidification dryer can significantly reduce the scrap rate, avoid quality defects caused by moisture, reduce rework and material waste, thereby improving production efficiency and saving costs.
Summary
In the PET bottle blowing industry, the plastic dehumidification dryer is a key equipment to ensure high-quality production. By using this equipment, companies can not only greatly improve the appearance and performance of the product, but also effectively reduce production costs and improve market competitiveness. Whether it is a mineral water bottle with high transparency requirements or a beverage bottle with high strength requirements, the plastic dehumidification dryer can ensure that the material processing in the production process is in the best state.
