Problems solved by technology

The construction of the anti-corrosion layer on the surface of the inner lining requires that the anti-corrosion layer has good adhesion, wear resistance, acid resistance, heat resistance, complete coverage, and can adapt to the sudden change of cold and heat in the chimney, but many current anti-corrosion layers cannot meet the requirements of the chimney. These requirements for anticorrosion

Embodiment 1

[0027] 1. Use a high-pressure water gun to clean the chimney concrete base 1 without leaving loose layers and floating ash.

[0028] 2. Use potassium silicate acid-resistant cement or sodium silicate acid-resistant cement 8 to fill the brick joints between the lining bricks. It is required to fill the joints immediately and the gaps are full.

[0029] 3. Spray a layer of primer material on the chimney concrete substrate 1 to form a primer layer 4. The primer material will soak into the brick body and combine with the brick body to have a certain repair effect on the brick body; the primer material can be Yes: epoxy resin, polyurethane resin, modified silicone resin, vinyl ester resin or silicone rubber, etc.

[0030] 4. Brush the high-temperature-resistant elastic bonding material on the base coat 4 to completely cover the brick surface and brick joints without missing areas. Bricks are staggered and uneven, and high temperature resistant elastic bonding materials need to be ...

Embodiment 2

[0033] 1. Use a high-pressure water gun to clean the chimney concrete base 1 without leaving loose layers and floating ash.

[0034] 2. Grind the substrate to make the chimney substrate smooth, maintain a smooth transition between bricks, and the unevenness between bricks does not exceed 3mm.

[0035] 3. Use potassium silicate acid-resistant cement or sodium silicate acid-resistant cement 8 to fill the brick joints, and fill the joints as soon as they are seen, and the gaps are full.

[0036] 4. Spray primer material on the base, the primer material will soak into the brick body and combine with the brick body, which has a certain repair effect on the brick body. The thickness of the primer layer is about 0.2mm (the primer material can be: ring epoxy resin, polyurethane resin, modified silicone resin, vinyl ester resin, silicone rubber, etc.).

[0037] 5. Spray a layer of VP3-2 on the leveling layer 5, then paste a layer of glass fiber cloth, and then spray VP3-2 to completel...

Abstract

The invention provides a method for making an anticorrosive glass reinforced plastic layer of a chimney. According to the method, the glass reinforced plastic layer of poly fluorine organic lining anticorrosive material is made after a base coating is coated on a basal body of the chimney. By the method, the inner wall of the chimney can be completely isolated with flue gas; the glass reinforced plastic of the poly fluorine lining anticorrosive material has good integrity, so construction blind spots are not caused; and the glass reinforced plastic of the poly fluorine lining anticorrosive material (VP3-2) has excellent properties such as acid resistance, abrasion resistance, heat resistance, strong adhesive force and the like, so the anticorrosive requirement of the chimney can be fully met.

Description

technical field [0001] The invention relates to an anticorrosion treatment technology for brick-lined chimneys used in industries such as thermal power plants, chemical industry and metallurgy. Background technique [0002] For brick-lined chimneys used in thermal power plants, chemical and metallurgical industries, anti-corrosion treatment is an important project, and the rationality of anti-corrosion layer design is particularly important. The construction of the anti-corrosion layer on the surface of the inner lining requires that the anti-corrosion layer has good adhesion, wear resistance, acid resistance, heat resistance, complete coverage, and can adapt to the sudden change of cold and heat in the chimney, but many current anti-corrosion layers cannot meet the requirements of the chimney. These requirements of anticorrosion. Contents of the invention [0003] The object of the present invention is to solve the problems in the prior art and propose a manufacturing pr...
