However, the appearance of plastic pipes is relatively ordinary, and it is not suitable to be exposed outside when decorating the home. It is usually buried in the wall, especially the water supply pipes in the shower set, which still use metal pipes, and a large proportion of them are made of brass. , high price, waste of resources, and the surface texture is hard, easy to get hurt when you touch it in the bath, and the safety is poor

Embodiment 1
[0017] Take a 6-meter-long ABS four-point pipe, first clean the outer surface, mainly to remove oil and absorb dust, and use alkaline reagent phosphate to wash away the dirt on the surface.
[0018] Immediately after surface etching, a mixture of chromic acid and sulfuric acid is used as an etching agent. Under the action of strong oxidizing chromic acid, the butadiene in ABS plastic is oxidized to form polar groups such as carbonyl and produce unevenness on the plastic surface. Uneven fixing points to allow for plating to occur.
[0019] Then use reducing hydrochloric acid to remove the residual chromic acid on the surface and clean it, otherwise the chromic acid will prevent the subsequent electroless plating from forming on the plastic surface, or the plating will partially adhere.
[0020] Secondly, after blocking the two ends of the four branch pipes, immerse them in a solution containing palladium chloride and tin dichloride, and then activate them in an acid solution to...

The invention discloses a high-bright composite plastic pipe. The high-bright composite plastic pipe is characterized by comprising a basic pipe body, a base layer and a high-bright decorating layer, the basic pipe body is an ABS (acrylonitrile butadiene styrene) pipe, a PVC (polyvinyl chloride) pipe or a PPR (polypropylene random) pipe and is the inner diameter being 1 / 2 inch or the inner diameter being 3 / 4 inch in size, the base layer is coppered, evenly wraps the outer surface of the basic pipe body and is 0.005mm-0.01mm in thickness, and the high-bright decorating layer is chromed or nickeled, is electroplated on the base layer and is 0.01mm-0.015mm in thickness. By the means, the high-bright composite plastic pipe is convenient to install during home decoration, optionally cuttable in length, capable of realizing good decorating effect while maintaining the characteristics of corrosion resistance, long service life, no pollution and low price of a common ABS water pipe, and particularly applicable to usage in outdoor places.
Description
technical field [0001] The invention relates to the field of home decoration plastic pipes, in particular to a high-brightness composite plastic pipe. Background technique [0002] Generally, the cold-galvanized steel pipes used in household tap water are prone to rust after about 5 years of service life. The iron smell is serious and the water quality turns yellow. Compared with traditional metal water pipes, plastic pipes are light in weight, corrosion-resistant, hygienic and safe, and easy to use. Long service life, easy installation and other characteristics are favored by home users and occupy a considerable proportion of the market, and have been more and more widely used in construction projects. However, the appearance of plastic pipes is relatively ordinary. It is not suitable to be exposed outside when decorating the home. It is usually buried in the wall, especially the water supply pipes in the shower set. Metal pipes are still used, and a large proportion of the...
