Q pyrolysis of low and high density polyethylene

Polyethylene (PE) and polypropylene (PP) are the two most widely used general-purpose thermoplastics. Therefore, they also account for a large proportion of discarded plastic waste. In order to eliminate waste plastic waste, the pyrolysis-catalytic modification (two-stage method) process can be used to convert waste plastic into oil products. However, due to the lack of research on the pyrolysis section of the two-stage method, there is a lack of detailed data on the cracking products and composition of resin and waste plastic, the decomposition speed of raw materials, and the selection of cracking temperature. This makes the two-stage production unstable and the product Quality is difficult to control. The effect of pyrolysis conditions on product yield and composition was studied, and it was found that at the same pyrolysis temperature, the composition and yield of the liquid phase products obtained by pyrolysis of resin and waste plastic were basically the same; while at 400°C to ...

HDPE culvert pipes are known for their durability, flexibility, and corrosion resistance, making them ideal for drainage and stormwater management applications. These pipes typically conform to AASHTO M294 or ASTM F2306 standards in the United States, which ensure they meet specific performance criteria. Sizes can vary widely, often ranging from 4 inches to 60 inches in diameter, with wall thickness varying according to the required load-bearing capacity. The pipes come in both perforated and solid forms, catering to different drainage needs. An important aspect of HDPE culvert pipe specs is the pipe’s stiffness, classified as either Type C, S, or D, indicating its resistance to deflection under load, with Type S being the most rigid. Installation requirements also highlight the importance of proper bedding and backfill to optimize performance and longevity. When selecting HDPE culvert pipes, it’s critical to consider factors like load, site conditions, and environmental im...

Energy-saving injection molding machines are designed to reduce energy consumption during the molding process, offering significant savings on electricity costs and reducing the environmental impact. These machines achieve energy efficiency through advanced technologies such as servo-driven hydraulics and all-electric operations, which precisely control the injection process and minimize idle power consumption. Leading suppliers in this sector include Engel, Haitian International, and Arburg, known for their innovative and efficient machinery. When choosing a supplier, consider the machine’s energy efficiency rating, the company’s reputation for quality and service, and the specific needs of your production, such as clamping force and injection volume. Investing in an energy-saving injection molding machine can lead to cost savings over time, making it a smart choice for businesses looking to enhance their sustainability and reduce operating costs.

Q are all high density polyethylene food safe
NinaBauer
CherryLucas Release Time: May 6, 2024, 11:40 AM
High-density polyethylene (HDPE) is widely recognized for its use in food-grade containers due to its chemical resistance and durability. However, not all HDPE containers are automatically safe for food contact. The safety for food contact is determined by the specific manufacturing processes and additives used during production. For example, some HDPE containers might be intended for industrial applications and could contain chemicals or coloring agents not approved for food contact. Therefore, it’s crucial to verify that any HDPE container intended for food use is explicitly labeled as food grade or has a certification from a relevant health or food safety authority. The presence of recycling code #2 (HDPE) can indicate recyclability but does not guarantee food-grade safety without additional confirmation.
