The influence of material quality and initial performance on service life

Material characteristics: The automotive urea plastic bucket is mainly made of high-density polyethylene (HDPE) and other materials. HDPE itself has good chemical stability and physical properties, which provide basic protection for the service life of plastic drums. Excellent HDPE material has a tight molecular chain structure, which can resist chemical erosion from urea solution and certain environmental factors. Generally speaking, these high-quality plastic buckets can be used for a longer period of time under normal usage conditions.

Initial manufacturing quality: The manufacturing process and quality control of plastic drums also have a significant impact on their service life. For example, in the injection molding or blow molding process, if the thickness of the barrel wall is uniform, there are no obvious stress concentration points or internal defects, then the strength and toughness of the plastic barrel will be better, and it can withstand the pressure, collision and other situations in daily use. Moreover, the quality of the sealing cover is equally crucial. Good sealing cover design and high-quality sealing materials can confirm that the plastic bucket maintains good sealing performance over a long period of time.

The impact of environmental factors on service life

Temperature environment: Temperature is one of the important factors affecting the service life of automotive urea plastic barrels. Plastic drums can maintain good performance within a suitable temperature range (generally recommended between -11 ℃ and 30 ℃). If the plastic bucket is exposed to high temperatures for a long time, such as in the hot summer, or near heat sources such as engines, the HDPE material will accelerate aging, causing the bucket body to become soft, deformed, and the sealing performance to decrease. On the contrary, in extremely cold environments, urea solution may crystallize. Although this mainly affects the use of urea solution, frequent crystallization and melting processes may also cause definite physical damage to the barrel, such as the generation of small cracks, thereby shortening the service life of plastic barrels.
