Embodiment Construction

[0006] The picture includes a white PP-R water pipe, which is characterized in that the white PP-R water pipe has three layers, the outer layer 1 and the inner layer 2 are white PP-R, and the middle layer 3 is black PP-R.

[0007] In the production, the co-extrusion method is used to produce a white PP-R water pipe with two layers of 1 and 2 white PP-R and a layer of 3 black PP-R. Since the middle layer 3 of the water pipe is black PP-R, it It can block sunlight from shining on the flowing water in the water pipe, prevent the growth of moss, and ensure the quality of water supply.

Abstract

The invention relates to a while random copolymerization polypropylene (PP-R) light resistant pipe which comprises a white (PP-R) water pipe. The while random copolymerization polypropylene (PP-R) light resistant pipe is characterized in that the white PP-R water pipe has three layers, the outer layer and the inner layer are white PP-R, and the middle layer is black PP-R. The invention can ensure the attractiveness of appearance and avoid influencing the water supply quality due to moss breeding in the water pipe.

Description

technical field [0001] The invention relates to a PP-R water pipe, in particular to a white random copolymerized polypropylene light-blocking pipe. Background technique [0002] At present, with the improvement of life, people pay more and more attention to water safety. Traditional zinc-iron pipes are less used because they are easy to rust and pollute tap water. In recent years, PP-R water pipes are popular because they will not rust and can ensure the safety of water supply. For the beauty of home decoration, white PP-R water pipes are mostly used, but because white PP-R water pipes are exposed to sunlight, moss will grow in the pipes, which seriously affects the quality of water supply. For this reason, some companies Produce other dark-colored PP-R water pipes such as black and green that can block sunlight. However, because dark-colored PP-R water pipes are more prominent in home decoration, they do not match the brighter designs of general kitchens and bathrooms. The...
