Technical prospect of bamboo winding pipe in Chongqing
- 2019-03-25-

      Chongqing Bamboo Winding PipeIt is a new type of bio-base pipe which is based on bamboo and resin as adhesive, which is processed by winding. Bamboo winding Pipe has the advantages of voltage resistance, insulation, corrosion resistance, light weight, convenient installation, long service life and so on. At the same time, the raw material of this technology is renewable resources. Only electricity and gas are consumed in the production process, and no exhaust gas, waste water and waste are discharged. Products in use of environmental friendliness is better, ecological environmental protection benefits are significant, in line with national environmental standards. The addition of adhesives and resins to bamboo winding tubes is an important process in the processing of bamboo winding pipe structure layer. In the existing technology, the leaching material is usually sprayed on the bamboo belt curtains by spraying. Because the Bamboo belt curtain takes a period of time after leaching to fully cover the whole bamboo belt curtain, so the spraying speed and bonding efficiency of the dipping material can not be effectively balanced. If the spraying speed is slow, then the amount of leachate discharged is too small to quickly cover the bamboo belt curtain, resulting in uneven distribution of leaching objects, if the spraying speed is too large, the leaching is too high consumption, waste is serious, the processing site is contaminated.

The raw material of traditional pipeline is non-renewable resources such as petrochemical industry or ore, and the production process has high energy consumption. Chongqing Bamboo Winding Pipe Technology innovation application Renewable bamboo resources, to provide low-cost, low-energy pressure pipeline solutions. Bamboo is one of the plants that grows fast and has a strong vitality. Three years can be a material, a forest, afforestation after the Chang. The Global bamboo forest area of about 22 million hectares, China accounted for 1/3 of the total area. It is a country rich in bamboo resources. Bamboo fiber is an enhanced material for winding composite tubes. The thin-walled hollow bamboo is processed into a continuous strip, and the amino resin is the binder. Pipeline is processed by winding process, no stress defects. Bamboo Composite Pipe has the advantages of high compressive strength, corrosion resistance, thermal insulation, good thermal insulation performance and low comprehensive cost, and satisfies the safety evaluation standard of drinking water transmission and distribution equipment. It can replace most of the traditional pipe on the market, such as welded steel pipe, polyethylene pipe, prestressed concrete tubular pipe, etc., widely used in water conservancy transportation, farmland water-saving irrigation, urban drainage and other pipeline transportation industry, greatly reducing the cost of pipeline use. Southeast of plastic, steel, cement and so on. In addition to pressure piping, bamboo winding composite technology can also be used in the manufacture of pipe galleries, large storage tanks and other products.

Chongqing Bamboo Winding Pipe also plays an important role in the green transformation of large state-owned enterprises. China Railway Construction Wangguoyu pointed out that China Railway 18 Bureau Group Bamboo Co., Ltd. is the Chinese Railway construction system designated with the National Bamboo Knitting Composite Engineering Technology R & amp; d Center cooperation enterprises. Attach importance to the cooperation with the National Bamboo Winding Composites Engineering Technology Research Center. A city pipe gallery around the world is located in Hohhot, Inner Mongolia, and the successful laying of Hengdian Industrial park has opened up a new milestone of green, low carbon and rapid economy for the construction of urban pipe corridor in China. He revealed that the group is currently building a bamboo winding composite pipe factory in Nanping, Fujian province, and plans to start production before the end of the year. This year, the country will build three to five new factories, according to market demand, gradually expand and radiate domestic and foreign markets. It is reported that China Railway construction 20 Bureau and Guangxi Yulin National Bamboo Winding Composite Engineering technology research and Development Center is also under construction.
