Copper waterstop
Key words:
Copper sealing plate is one of the many products produced by copper (copper elemental, named for its color purple). Copper is not only industrial pure copper, but also may contain a certain amount of oxygen and other deoxidation elements or alloying elements to improve its material and performance. Its relative density is 8.9, the color is rose red, and the surface is purple after forming an oxide film.
Key words:
Excellent corrosion resistance: copper sealing plate has excellent corrosion resistance and can maintain stable performance in humid, acid and alkali and other harsh environments for a long time. This feature makes it in the need for long-term contact with corrosive media occasions, such as water conservancy projects, sewage treatment, etc., can play a good water stop effect.
Key words:
The specifications and sizes of the copper sealing plate are diverse to meet the needs of different projects. Generally speaking, its thickness ranges between 0.5-5mm, the width can reach 1000mm, and the length can reach 15000mm. In addition, the tensile strength of the copper water seal is not less than 240Mpa, the elongation is not less than 30%, and its chemical composition and physical properties must meet the provisions of relevant national standards.
Key words:
Water conservancy projects: such as DAMS, reservoirs, levees, channels and other projects to stop the water, to ensure that the project in the long-term use of the process does not appear leakage problems.
