Description

Technical Field

[0001] This utility model belongs to the field of polymer material pipe technology, specifically, it relates to a PU polyurethane hose. Background Technology

[0002] In industrial production and various fluid transportation scenarios, hoses are key transportation components, and their performance directly affects the stability, safety, and transportation efficiency of the entire system. Traditional rubber hoses, as an early and widely used type of transportation hose, have revealed many problems that urgently need to be addressed in long-term practical application.

[0003] Rubber is affected by various factors in the natural environment, such as oxygen, ozone, ultraviolet radiation, and temperature changes, resulting in a series of complex physical and chemical changes.

[0004] While existing polyurethane hoses possess a certain degree of flexibility, they suffer from drawbacks such as insufficient tensile strength and limited temperature resistance. For temperature-sensitive materials, temperature fluctuations can alter their physical or chemical properties, thereby affecting material transport efficiency. Poor insulation of the hose itself can lead to changes in its performance. When transporting high-temperature fluids, excessively high temperatures on the hose's outer surface can impact the surrounding environment and even cause safety accidents such as fires. Furthermore, high temperatures can accelerate the aging of the hose's internal materials, shortening its service life.

[0005] In view of this, this utility model is proposed. Utility Model Content
