Nano antibacterial stainless steel plastic composite pipe was recently launched and put on the market, once again to the hot pipe market in recent years to push the wave. Experts identified that the pipe in the product design, nano antibacterial material technology application and pipe connection and other aspects of innovation, add a domestic blank, this pipe is the use of today’s advanced production technology and raw materials at home and abroad to produce a new composite pipe with antibacterial self-cleaning function. It is made of nano antibacterial agent and the relevant antibacterial carrier and thermoplastic mixed into antibacterial masterbatch, then and thermoplastic, hot melt glue by extrusion for the inner plastic tube, and then in the outer layer with stainless steel cover, after welding, grinding, polishing, beautiful appearance, quite decorative effect, can be used for indoor water supply, gas supply, heating, especially for pure water, beverage, food industry, hot and cold water supply to provide A new type of safe pipe. The outer layer of the pipe is covered with stainless steel, which is both rust and corrosion resistant, and the inner plastic layer is not in direct contact with sunlight or the atmosphere, which reduces the ageing rate and greatly improves the life of the pipe and is cost effective. Its biggest feature is the broad-spectrum anti-bacteria, ordinary pipe after long-term use, the inner surface of the pipe is easy to adhere to the breeding microorganisms, in the wall of the pipe to form a bacterial layer, resulting in a decline in water quality, and nano antibacterial stainless steel composite pipe effectively solve this problem, by the Guangdong Provincial Microbiological Analysis and Testing Centre and Shaanxi Province Centre for Disease Control and Prevention and other departments, its kill rate of Escherichia coli, glucococcus aureus, etc. in 97% or more, and antibacterial ability long lasting.
