PB water supply pipe for low-temperature ground radiation heating

Abstract

The invention discloses a PB water supply pipe for low-temperature ground radiation heating in the technical field of water delivery pipe products. The PB water supply pipe comprises a heat-conductinglayer, wherein the outer wall of the heat-conducting layer sleeves a PB pipe body, the outer wall of the PB pipe body sleeves an antibacterial oxygen-barrier layer, and the outer wall of the antibacterial oxygen-barrier layer sleeves a heat preservation layer. A polyurethane layer and a TPU layer arranged in the heat preservation layer respectively have excellent heat preservation and abrasion resistance properties, so that heat loss of hot water in the pipe is not caused, the pipe has abrasion resistance in use, an arranged nano antibacterial PB layer has an antibacterial effect, an arrangedEVOH layer has the effect of preventing oxygen from seeping into the pipe, the situation can be effectively prevented that metal parts in a heating system are damaged due or oxygen seepage in the pipe, the service life of the pipe body and the service life of the whole heating system are effectively prolonged, and the arranged heat-conducting layer has an excellent heat-conducting effect. The PBwater supply pipe has the excellent heat-conducting, heat-preservation, antibacterial and oxidation resistant properties.

Description

technical field [0001] The invention relates to the technical field of water delivery pipes, in particular to a PB water supply pipe for low-temperature ground radiation heating. Background technique [0002] PB is a high molecular inert polymer, which is polybutene. Polybutene is made by the polymerization of butene. It is an ecological hydrocarbon product. From the structural point of view, polybutene is a linear Isotactic semi-crystalline thermoplastic material, non-toxic and pollution-free during processing and use, can be heated and formed repeatedly, and combines the advantages of sanitation, processability, surface finish, strength, flexibility and connectivity. , thermodynamic properties and functionality have been comprehensively balanced. Plastic pipes have good flexibility and pressure resistance, and are widely used in building floor heating construction. However, the existing plastic pipes have poor thermal insulation performance and hot water It is easy to cau...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a PB water supply pipe for low-temperature ground radiant heating to solve the problem of poor thermal insulation performance of the plastic pipe proposed in the above background technology, hot water in the pipe is likely to cause heat loss, wasteful, and oxygen molecules are easy to pass through. The plastic layer penetrates into the water in the tube, causing the growth of some aerobic bacteria, and also has the problems of poor thermal conductivity and slow temperature rise.
