PE composite antibacterial water feed pipe

Abstract

The invention relates to a PE composite antibacterial water supply pipe, which belongs to the technical field of PE pipe manufacture. It is composed of an outer layer and an inner layer. The outer layer is a black protective layer, and the inner layer is a white antibacterial layer. Antimicrobial plastic layer made after mixing. The white antibacterial layer of the present invention contains 0.4 to 2.0% of inorganic antibacterial agents and a very small amount of silver ions and zinc ions, and has a wide range of inhibitory effects on gram-negative bacteria, gram-positive bacteria, fungi, molds and algae, It is safe and non-toxic, meets the requirements of various hygienic standards for plastic pipes, and does not need to make many changes to the pipe processing technology. During the use of the PE composite antibacterial water supply pipe, bacteria and other microorganisms cannot grow and survive on the surface of the white antibacterial layer in the inner layer of the water supply pipe, so the self-cleaning performance of the pipe can be realized once and for all, and the secondary pollution problem of drinking water can be completely solved.

Description

technical field [0001] The invention relates to a PE composite antibacterial water supply pipe, which belongs to the technical field of PE pipe manufacture. Background technique [0002] The standard domestic drinking water output from the waterworks is transported to thousands of households through water supply pipelines such as cast iron pipes, steel pipes and ordinary plastic pipes. Due to the long path of the water pipeline, these pipelines lack antibacterial and antibacterial functions. Therefore, various harmful bacteria, molds and other microorganisms will breed and spread in the transported water, causing bacteria in the water to attach and grow on the inner wall of the pipeline, forming a layer of yellow, sticky and sticky bacterial clusters, called "biofilm". This layer of biofilm can make various microorganisms (including pathogens) multiply and thicken layer by layer. Finally, when the biofilm falls off, pieces of bacteria will flow out of the faucet along the wa...

Problems solved by technology

[0003] According to reports, some tap water pipes have been used for a period of time to sample the dirt on the inner wall of the pipe. The test results are: there are yellow rust tumors, containing microorganisms such as bacilli, cocci, and bacteria; Bacillus, intestinal bacteria, resident bacteria, Acinetobacter, Aeromonas, Arthrobacter, Bacillus, etc.; even the growth of chlorine-resistant microorganisms such as Strain Spirulina and Chlorella, etc., which cause great harm to drinking water
