Embodiment 1
[0030] Such as figure 1 As shown, the anticorrosion method for the rigid-flexible composite integral castable lining of the wet chimney of the thermal power plant is characterized in that the specific steps are as follows: 1) First, apply the two-component silicone rubber on the surface of the structural concrete or steel inner cylinder with a thickness of 3mm If necessary, apply an interface agent or a leveling mortar layer on the inner side of the concrete cylinder wall, as the inner layer of the anti-corrosion sealing layer and the adhesive for pasting the glass steel plate; mm thick prefabricated heat-resistant and corrosion-resistant glass steel plate of a specific shape is extruded and pasted on the two-component silicone rubber, and then pasted with three oils and two cloths at the joint of the glass steel plate, that is, using "resin- The glass fiber mesh cloth-resin sealing strip makes the glass fiber reinforced plastic also form a whole sealed cylinder, and the rigid...

[0033] The anti-corrosion method for the rigid-flexible composite integral castable lining of wet chimneys in thermal power plants is characterized in that the specific steps are as follows: 1) First, the polymer-modified asphalt is coated on the surface of the structural concrete or steel inner cylinder with a thickness of about 3mm. If necessary, apply an interface agent or a leveling mortar layer on the inner side of the concrete cylinder wall as the inner layer of the anti-corrosion sealing layer and the adhesive for pasting the glass steel plate; The prefabricated heat-resistant and corrosion-resistant glass steel plate of a specific shape is extruded and pasted on the polymer modified asphalt, and then the "resin-glass fiber The mesh cloth-resin sealing strip makes the glass fiber reinforced plastic also form an integral sealing cylinder. As the rigid waterproof and corrosion-resistant outer layer of the anti-corrosion sealing layer, it needs to be inspected and accepted ...

[0036] The anti-corrosion method for the rigid-flexible composite integral castable lining of wet chimneys in thermal power plants is characterized in that the specific steps are as follows: 1) First, apply the butadiene rubber on the surface of the structural concrete or steel inner cylinder with a thickness of about 3mm, if necessary At the same time, apply interface agent or leveling mortar layer on the inner side of the concrete cylinder wall, as the inner layer of the anti-corrosion sealing layer and the adhesive for pasting the glass steel plate; The temperature-resistant and corrosion-resistant glass steel plate of a specific shape is extruded and pasted on the butadiene rubber with staggered seams. The sealing strip makes the glass fiber reinforced plastic also form an integral sealing cylinder. As the rigid waterproof and corrosion-resistant outer layer of the anti-corrosion sealing layer, it needs to be checked and accepted by the quality inspection personnel again; t...
