Due to said structure, whole connecting sewing can be sealed effectively, make whole anticorrosive coat have good permeability resistance, abrasion resistance and endurance quality are all good, and antiseptic effect is better.
The anti-corrosion layer structure at chimney inner beam place of thermal power plant of the present utility model, described rubber anti-corrosive layer is made up of butyl rubber.
Due to said structure, make rubber anti-corrosive layer have good Corrosion Protection, make antiseptic effect better, thus anti-corrosion layer structure is more stable, longer service life.
The anti-corrosion layer structure at chimney inner beam place of thermal power plant of the present utility model, the thickness of described glass flake anticorrosive coat is 2.9mm, and the thickness of described rubber anti-corrosive layer is 3.1mm, and the thickness of described Corrosion Protection of Fiber Reinforced Plastics layer is 3.2mm.
Due to said structure, make the antiseptic effect of each anticorrosive coat better, make anticorrosive coat reach instructions for use simultaneously, be applicable to applying.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, the anti-corrosion layer structure at chimney inner beam place of thermal power plant of the present utility model; mainly solve the aseptic technic problem of establishing gap, crossbeam place in chimney; acid liquid corrosion and sweep of gases can be placed; avoid acid solution to enter between crossbeam and wall base body and corrosion is caused to chimney, good protective effect is played to inner wall of stack, favorable anti-corrosion effect; anti-seismic performance is good; cost is lower, and difficulty of construction is low, and the life-span is permanent.
2, the anti-corrosion layer structure at chimney inner beam place of thermal power plant of the present utility model, structure is simple, is skillfully constructed, effectively can solve that this position the most easily occurs because of vibration cause anticorrosive coat to come off, the problem such as destruction because slurries wash away, extend service life, maintenance cost can be reduced to greatest extent.
