Water purifier water pipe and manufacturing method thereof

Abstract

The invention discloses a water purifier water pipe and a manufacturing method thereof. The water purifier water pipe is formed by mixing rotational-moulding-grade linear polyethylene, low-density polyethylene and polyolefin plastomer according to a mass ratio and manufactured through the steps of mixing, feeding, high-temperature adhesive melting, extruding, vacuum water cooling, drawing, pipe cutting, checking and packaging. The water purifier water pipe can achieve a third-level ultraviolet-resistant effect, has quite high ageing resistance and quite high material strength, does not turn yellow in long-term use with the color never changing and does not crack after being repeatedly folded 1000 times, and meanwhile added antibacterial nano-silver powder can effectively kill or resist bacteria and greatly improve the use value of the water purifier water pipe.

Description

technical field [0001] The invention relates to the technical field of water pipes, in particular to a water purifier water pipe and a manufacturing method thereof. Background technique [0002] In the food, environmental protection and other industries, polyethylene materials are odorless, non-toxic, waxy, and have excellent low temperature resistance due to their excellent performance. , can withstand most acid and alkali erosion, does not breed bacteria and other characteristics, and has been widely used. However, its disadvantages are also obvious, such as fear of ultraviolet rays, easy aging, yellowing of the product, intolerance to twists and turns, and repeated bending will easily cause the material to age rapidly. While not breeding bacteria, it cannot effectively inhibit bacteria. [0003] At present, the equipment used for pipe making at home and abroad is mainly based on extruders. The pipes made by extruders have low UV resistance. Although the performance is im...

Problems solved by technology

However, its disadvantages are also obvious, such as fear of ultraviolet rays, easy aging, yellowing of the product, intolerance to twists and turns, and repeated bending will easily cause the material to age rapidly. While not breeding bacteria, it cannot effectively inhibit bacteria

[0003] At present, the equipment used for pipe making at home and abroad is mainly based on extruders. The pipes made by extruders have low UV resistance. Although the performance is improved after blending with linear polyethylene, the performance is not obvious. Additional anti-UV agents make the pipes The cost increases, and the pipe is not resistant to bending and aging

[0004] The water pipes currently used in the water purifier market are prone to aging and have weak UV resistance. Exposure to sunlight will cause the pipes to age rapidly, resulting in problems such as pipe bursts, water leakage, low toughness, and easy breakage.

During the use of the water purifier, due to the different water quality in different places, the use time of the filter element is too different, and it is easy to cause the filter element to fail suddenly when not paying attention during use, so that the unpurified water remains in the water pipe, which leads to drinking water problems.
