Embodiment Construction

[0027] Such as figure 1 , 2 . The lightweight graphite resistance-reducing module shown in 3 has a grounding connection line 2, and the grounding connection line 2 runs through the grounding module 1, and the two sides of the grounding module 1 are laid with expanded graphite layers 3 layer by layer from the inside to the outside and glass fiber mesh cloth 4, the outermost layer of the grounding module is provided with a wrapping layer 5 that wraps the entire grounding module, and the grounding module is pressed into a fixed module by a mold.

[0028] The ground connection wire is a graphite braid or a metal or other graphite ground cable.

[0029] The shape of the ground connection wire is a flat block, a strip, a cylinder or an irregular cube.

[0030] The wrapping layer is graphite drag-reducing cloth, carbon fiber mesh cloth, glass fiber mesh cloth or metal braided mesh.

[0031] The size of the grounding module is 510mm*410mm*60mm.

[0032] The preparation method of t...

Abstract

The invention discloses a lightweight graphite resistance reduction module and a preparation method thereof. The lightweight graphite resistance reduction module is prepared form expanded graphite, glass fiber mesh cloth, graphite resistance reduction cloth and graphite woven belt material. The lightweight graphite resistance reduction module can be made into a block shape, a plate shape or a cylindrical shape and is high in plasticity and structural strength. The preparation method includes the processes of laying, fixing, pressing, coating and re-pressing. The lightweight graphite resistancereduction module has the advantages of being small in density, light in weight, high in strength, good in water absorption, excellent in electrical conductivity and the like.

Description

technical field [0001] The invention belongs to the technical field of non-metal lightning protection and grounding, and in particular relates to a lightweight graphite resistance-reducing module and a preparation method thereof. It has the advantages of good electrical conductivity, good water absorption, high structural strength, light weight, and easy handling. Background technique [0002] The grounding modules on the market are mainly made of graphite powder, cement, inorganic salt and other materials, which are heavy, poor in conductivity, and difficult to transport and install. [0003] For example, a grounding module disclosed in Publication No. 103199349A includes a module body, which is characterized in that: the basic composition of the formula of the module body is as follows: 13-17 parts of coke powder, 1.5-8 parts of cement, 0.3-5 parts of graphite powder The said part is a weight part; said formula also includes 0.3-5 parts of an ion releasing agent, and said...
