Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing equipment, in particular to a flame retardant ABS plastic drying and cooling machine. Background Art

[0002] ABS plastic is a thermoplastic plastic with good heat resistance, cold resistance, impact resistance and chemical corrosion resistance. It is a "tough, hard and rigid" material with easy raw materials, good comprehensive performance, low price and wide application. It has been widely used in manufacturing industries such as machinery, electrical, textile, automobile, aircraft, and shipbuilding, as well as chemical industry. Flame retardant ABS is made by adding flame retardants to ABS to achieve flame retardant effect. ABS plastic is easy to absorb moisture during production and processing. Moisture will cause the performance of plastic products to decline, such as increased internal stress, easy cracking, and decreased transparency. Using a dry cooler can effectively remove moisture from plastic raw materials to ensure the quality and performance of products.

[0003] At present, when the ABS plastic drying and cooling machine is in use, the added flame-retardant ABS plastic will pile up, reducing its surface area, causing the heat transfer and moisture emission of the flame-retardant ABS plastic to be affected, thereby slowing down the drying process and reducing the drying efficiency.
