Problems solved by technology

Low-grade gasoline, diesel oil, etc. have low technical level, complicated preparation methods, narrow application areas, low added value, and high energy consumption, which is easy to cause secondary pollution. However, the cost of heat shrinkable materials and coating materials made by previous inventions is high. Cannot be used as pipe wrapping material
