RITABLE Underfloor heating systems have become increasingly popular as a method of indoor heating, utilizing the heat dissipation from the floor. Within these systems, the EVOH layer plays a crucial role. This article will elaborate on the functions of the EVOH layer in underfloor heating pipes, including antioxidation, oxygen barrier, strength enhancement, permeability, and environmental friendliness.

1.Antioxidation - Protecting the pipe material

An important function of the EVOH layer in underfloor heating pipes is to prevent oxygen permeation. When the water in the underfloor heating system comes into contact with air, it can lead to oxidation and corrosion of the metal pipes, resulting in pipe aging. The EVOH layer possesses excellent gas barrier properties, effectively blocking the penetration of oxygen and protecting the pipe material from oxidation, thereby extending its service life.

2.Oxygen barrier - Enhancing thermal efficiency

The EVOH layer also provides excellent oxygen barrier properties. In underfloor heating systems, the water temperature is relatively high, and the entry of oxygen into the pipes can cause water contamination, bubble formation, and rust, thereby reducing the heating efficiency. The oxygen barrier properties of the EVOH layer effectively prevent external oxygen from infiltrating, maintaining water quality cleanliness, and improving thermal efficiency.

3.Strength enhancement - Increasing pipe durability

The EVOH layer in underfloor heating pipes also strengthens the pipe structure. The water pressure in underfloor heating systems can be significant, especially during peak heating periods in winter. The EVOH layer exhibits high strength and toughness, effectively increasing the pipe's resistance to pressure, reducing the risk of pipe deformation or rupture, and ensuring the safe operation of the underfloor heating system.

4.Permeability - Regulating moisture loss

The EVOH layer in underfloor heating pipes also possesses a certain level of permeability. In underfloor heating systems, hot water is supplied through the pipes, and moisture loss can affect the heating efficiency. The EVOH layer can regulate the permeation rate of moisture appropriately, preventing excessive water loss, maintaining the stability of the heating system, and improving heating performance.

5.Environmental friendliness - Recyclability

Lastly, another important function of the EVOH layer in underfloor heating pipes is its environmental friendliness. The EVOH layer is a polymer material that exhibits higher recyclability and reusability compared to other pipe materials used in underfloor heating systems. After the end of the system's lifespan, the EVOH layer can be recycled, reducing environmental pollution and facilitating sustainable resource utilization.

In conclusion, the EVOH layer plays multiple roles in underfloor heating pipes, including antioxidation, oxygen barrier, strength enhancement, permeability, and environmental friendliness. It protects the pipe material from oxidation, improves thermal efficiency, increases pipe durability, regulates moisture loss, and demonstrates good sustainability by being recyclable. Therefore, the application of the EVOH layer in underfloor heating systems is of significant importance.
