Embodiment 1
[0022] like figure 1 As shown, the cross-sectional view of the expansion joint made for the steel inner cylinder of the chimney. The chimney steel inner tube expansion joint is composed of adhesive 2, anti-corrosion brick 3, "L" shaped bead 4, nail 5 and skin 6. After the steel substrate 1 is cleaned, apply the adhesive 2 on the steel substrate 1 and the skin 6 to bond the two, and then fix and compact the skin 6 with an "L"-shaped bead 4 and nails 5, and the skin 6 fill the filler 7 in the back groove, so that the skin 6 maintains the required amount of expansion and contraction. The skin 6 is pasted on the inner wall of the inner tube of the chimney in a circle, the "L" shaped bead 4 presses the skin 6, the adhesive 2 is applied on the "L" shaped bead 4, and the anti-corrosion brick 3 is pasted in a circle, figure 2 shown.
[0023] The thickness of the "L" shaped bead 4 is 10mm, the width of the long side is 50mm, and the width of the short side is 50mm, and the material...
Embodiment 2
[0028] The present invention is a chimney steel inner cylinder expansion joint, the thickness of the "L" shaped bead 4 is 2mm, the width of the long side is 20mm, the width of the short side is 1mm, the thickness of the anticorrosion brick 3 is 10mm, and the filler 7 is foamed polyurethane.
[0029] The production steps of bead 4 are as follows: use the stainless steel "L" mold made in advance, clean the surface with a styrene solution with a concentration of 99%, and after it dries, dip the upper latitude 907-P resin with a wool roller to 80ml , evenly roll-coated on the inside of the mold, and then spread the single-layer alkali-free glass fiber cloth cut in the shape of "L" on the mold, and then use a roller dipped in 80ml of resin to roll-coat the alkali-free glass fiber cloth to make the resin soak into the alkali-free glass. The fiber cloth is compacted with a defoaming roller. After it has been gelled, the excess irregular parts are cut off, which is the finished product...
Embodiment 3
[0032] The present invention is a chimney steel inner cylinder expansion joint, the thickness of the "L" shaped bead 4 is 20mm, the width of the long side is 100mm, the width of the short side is 100mm, and the thickness of the anti-corrosion brick 3 is 75mm.
[0033] The production steps of bead 4 are as follows: use the stainless steel "L" mold made in advance, clean the surface with 99% styrene solution, after it is dry, dip the upper latitude 907-P resin with a wool roller to 100ml , evenly roll-coated on the inside of the mold, and then spread the single-layer alkali-free glass fiber cloth cut in the shape of "L" on the mold, and then use a roller dipped in 100ml resin to roll coat the alkali-free glass fiber cloth to make the resin soak into the alkali-free glass. The fiber cloth is compacted with a defoaming roller. After it has been gelled, the excess irregular parts are cut off, which is the finished product; the number of layers of alkali-free glass fiber cloth can be...
