Preferably, the activated carbon fiber cloth 2 is braiding or non-woven acf layer.Since electrode mechanism is arranged
In carbon fiber bed end, carbon fiber bed is formed using the stacking of activated carbon fiber cloth 2, it requires that carbon fiber needs are woven into
Layer structure, such as common activated carbon eyelet fabric.The non-woven form such as activated carbon fiber cloth 2 or activated carbon-fiber felt, equally
It is that layer structure is suitable for making electrode in non-laminated wheat flour.

Ingredient is combined together conducting particles by the bonding effect of matrix resin, forms conductive path, and leading for material is glued in realization
Electrical connection.Since contacting with each other between conducting particles to form conductive path, keep conducting resinl conductive, it is interparticle in glue-line
Steady contact is as caused by conductive adhesive curing or drying.
For conducting resinl before solidification or drying, conducting particles is existing for separation, not connect continuously each other in adhesive
Touching, thus it is in state of insulation.After conductive adhesive curing or drying, gluing is caused due to the volatilization of solvent and the solidification of adhesive
The contraction of agent volume, making conducting particles each other is in stable continuous state, thus shows electric conductivity.It is conductive in the present invention
Glue uses naturally dry or drying.Preferably, when the conducting resinl is graphite based conducting glue, the conducting resinl area 1 is using baking
Dry curing molding.Due to graphite based conducting glue naturally dry it is difficult to ensure that intensity after solidifying, solidification are needed in certain temperature
Lower progress.Preferably, drying temperature is 60~100 DEG C, and drying time is 30~150min, not only can guarantee solidification intensity, but also energy
Reduce the mass loss and micropore loss of activated carbon fiber at high temperature.
