Embodiment 1

[0017] like figure 1 As shown, a new type of antibacterial PE pipe, the outer layer is PE pipe layer 1, and the inner wall of PE pipe layer 1 is provided with a layer of inorganic antibacterial layer 2 through co-extrusion, and the inorganic antibacterial layer 2 slowly releases a small amount of silver ions under the condition of pipeline humidity , because the surface of the bacteria is negatively charged, the positively charged silver ions are adsorbed on the surface of the bacteria, thereby disrupting its electrolyte balance, resulting in the death of the bacteria due to cell damage. Another point of view is that silver ions enter the inside of bacteria, react and combine with bacterial cell enzymes, inhibit the activity of bacteria and the reproduction and regeneration of bacteria, and achieve the effect of killing bacteria.

[0018] Inorganic antibacterial layer 2 can adopt IONPURE material provided by Japan Ishizuka Glass Co., Ltd., which uses silver ions as an active i...

Embodiment 2

[0021] In this embodiment, the wall thickness of the PE pipe layer 1 is 4 mm, and the thickness of the inorganic antibacterial layer 2 is 0.5 mm.

Embodiment 3

[0023] In this embodiment, the wall thickness of the PE pipe layer 1 is 6.2 mm, and the thickness of the inorganic antibacterial layer 2 is 0.7 mm.

Abstract

A novel antibacterial PE pipe relates to construction pipes. The outer layer is PE pipe. The invention is characterized in that the inner wall of the PE pipe is provided with a layer of inorganic antibacterial layer by co-extrusion. In the invention, the thickness of the pipe wall of the PE pipe is between 2mm and 10mm. The thickness of the inorganic antibacterial layer is between 0.3mm and 1.0mm. The invention has the beneficial effect that the novel antibacterial PE pipe integrates antibacterial property, energy saving, sanitation and self-cleaning, which can be directly applied to the transportation system of purified water. The invention is a novel green and environmentally-friendly construction material. The thermal coefficient is only 2 percent of the metal pipe and the hot-water pipe has excellent heat insulating and energy saving effects. Adopting the consubstantial hot melt connection, the tubes and the pipes have the advantages of no leakiness, high toughness and strong heat resistance and creep resistance. When used under normal pressure and temperature, the service life of the tubes and the pipes can be 50 years.

Description

Technical field: [0001] The invention relates to building pipes, in particular to a novel antibacterial PE pipe. Background technique: [0002] Medical research shows that the root cause of human diseases is the invasion of the human body by various harmful bacteria and viruses, some bad living habits in people's daily life, especially the complex living environment and conditions we depend on for survival , All may become conditions and opportunities for various harmful germs and viruses to infringe on the human body, thereby endangering human health and producing various diseases. [0003] With the continuous development and evolution of society, it is very significant and urgent for the general public to improve their quality of life and social living environment, especially the improvement of their health awareness. How to effectively prevent and control the invasion of various harmful viruses and germs, improve the quality of life, ensure good health, and purify the li...
