Copper plate,Copper strip, Zitong Waterstop is one of many products produced by Zitong.

The main characteristics of the copper water-stop steel plate are: strong corrosion resistance; high strength, can withstand large deformation; the appearance is clear, without cracks, creasing, and pits.

The role of copper tape is explained:

The copper belt is suitable for the foundation water stop, the water stop of the dam body, the water stop of the dam, the water stop of the corridor, and the water stop of the holes in the dam, the water stop of the powerhouse, the water stop of the transverse joints under the overflow surface, etc. . It is used for the concrete pouring of expansion joints such as gates, dam bottoms, construction projects, underground constructions, etc., and then guarantees the service life of the construction.

Red copper is a simple substance of copper, so named because of its purple-red color. See copper for various properties. Red copper is industrial pure copper with a melting point of 1083°C, no allotrope changes, and a relative density of 8.9, which is five times that of magnesium. It is about 15% heavier than ordinary steel. It has a rose red color, and is purple after the oxide film is formed on the surface, so it is generally called copper. It is copper containing a certain amount of oxygen, so it is also called oxygen-containing copper. The copper is named for its purple-red color. It is not necessarily pure copper, and sometimes a small amount of deoxidizing elements or other elements are added to improve the raw materials and performance, so it is also classified as a copper alloy.

my country's copper processing materials can be divided into: general copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and high-purity, vacuum oxygen-free copper), deoxidized copper (TUP, TUMn), adding a small amount of alloy Four types of elemental special copper (arsenic copper, tellurium copper, silver copper). The electrical conductivity and thermal conductivity of copper is second only to silver, and it is widely used to make electrical and thermal devices. Red copper has outstanding corrosion resistance in the atmosphere, sea water, certain non-oxidizing acids, alkalis, salt solutions and a variety of organic acids, and is used in the chemical industry.

Waterstop copper tape is the first step in the production of different types and standard waterstops. Therefore, the width, thickness and elongation of the produced waterstop copper sheet are closely related to the corresponding data of the waterstop copper sheet. In the original standard for water-soil constructions, the thickness of the water-stop copper tape is specified to be 0.8mm~1.0mm, and the thickness of the water-stop copper tape actually used in some dams is 1.2mm. Therefore, this standard defines the thickness of the water-stop copper tape Change to 0.8mm~1.2mm.
