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
The present invention relates to the preservative treatment technology of the brick lining chimney of industries uses such as thermal power plant, chemical industry and metallurgy.
Background technology
For the brick lining chimney that industries such as thermal power plant, chemical industry and metallurgy are used, preservative treatment is an important engineering, and the reasonability of anticorrosive coat design just seems particularly important.Anticorrosive coat construction is at liner surface, require anticorrosive coat have preferably adhesive ability, wear-resisting, acidproof, heat-resisting, cover fully, can adapt to cold and hot cataclysm in the chimney, but present a lot of anticorrosive coats all can not satisfy these requirements of chimney anticorrosion.
Summary of the invention
The objective of the invention is to problem, propose by the manufacture craft of poly-fluoropolymer organic lining anticorrosive material fiberglass as the chimney anticorrosion layer at the prior art existence.
Technical scheme of the present invention is as follows:
A kind of fiberglass anticorrosive coat preparation method of chimney anticorrosion, its step is as follows:
(1) cleaning chimney matrix is removed the unconsolidated formation of matrix and is floated ash;
(2) use potassium silicate acid resistant adhesive mortar or sodium metasilicate acid resistant adhesive mortar that the brickwork joint between the liner tile is filled up, ask for an interview to that seam is just mended, brickwork joint is full, make between brick and the brick to seamlessly transit;
(3) spraying one deck priming coat on the chimney matrix, the material of priming coat adopts epoxy resin, polyurethane resin, modified organic silicone resin, vinyl ester resin or silicon rubber, and about 0.2mm is better for primer thickness;
(4) brush high temperature resistant elastomeric adhesives on priming coat, form level and smooth screed-coat, screed-coat thickness is 1～3mm;
(5) spraying one strata fluoropolymer organic lining anticorrosive material on screed-coat sticks layer of glass fiber fabric then, and glass cloth and poly-fluoropolymer organic lining anticorrosive material are combined closely; The poly-fluoropolymer organic lining anticorrosive material of spraying is produced poly-fluoropolymer organic lining anticorrosive material frp layer to covering glass cloth fully again, and the gross thickness of poly-fluoropolymer organic lining anticorrosive material frp layer is 0.5～1.0mm;
Wherein, high temperature resistant elastomeric adhesives adopts silicon rubber, silicone adhesive, fluorosioloxane rubber or polyurethane adhesive;
Described poly-fluoropolymer organic lining anticorrosive material adopts the poly-fluoropolymer organic lining anticorrosive material of announcing among the Chinese invention patent document CN101891993A " the poly-fluoropolymer organic lining anticorrosive material and the processing method of chimney, flue and other pipeline and container ".
The present invention also proposes another kind of method:
A kind of fiberglass anticorrosive coat preparation method of chimney anticorrosion, its step is as follows:
(1) cleaning chimney matrix is removed the unconsolidated formation of matrix and is floated ash;
(2) polishing chimney matrix is extremely smooth substantially, the concavo-convex 3mm that is no more than between brick and the brick;
(3) use potassium silicate acid resistant adhesive mortar or sodium metasilicate acid resistant adhesive mortar that the brickwork joint between the liner tile is filled up, ask for an interview to that seam is just mended, brickwork joint is full, make between brick and the brick to seamlessly transit;
(4) spraying one deck priming coat on the chimney matrix, material selection epoxy resin, polyurethane resin, modified organic silicone resin, vinyl ester resin and the silicon rubber of priming coat, about 0.2mm is better for primer thickness;
(5) (priming coat herein is not the screed-coat of method 1 at priming coat, the polishing operation is arranged in this technology, so just do not need screed-coat, if there is not the technique for grinding will screed-coat) go up spraying one strata fluoropolymer organic lining anticorrosive material, stick layer of glass fiber fabric then, glass cloth and poly-fluoropolymer organic lining anticorrosive material are combined closely; The poly-fluoropolymer organic lining anticorrosive material of spraying is produced poly-fluoropolymer organic lining anticorrosive material frp layer to covering glass cloth fully again, and the gross thickness of poly-fluoropolymer organic lining anticorrosive material frp layer is 0.5～1.0mm.
Wherein, high temperature resistant elastomeric adhesives adopts silicon rubber, silicone adhesive, fluorosioloxane rubber or polyurethane adhesive.
Described poly-fluoropolymer organic lining anticorrosive material adopts the poly-fluoropolymer organic lining anticorrosive material of announcing among the Chinese invention patent document CN101891993A " the poly-fluoropolymer organic lining anticorrosive material and the processing method of chimney, flue and other pipeline and container " (product code name VP3-2).
The technology that the present invention proposes can be kept apart inner wall of stack and flue gas fully.Poly-fluoropolymer organic lining anticorrosive material fiberglass has globality preferably, the blind spot of constructing can not occur.Poly-fluoropolymer organic lining anticorrosive material (VP3-2) fiberglass has superior functions such as good acidproof, wear-resisting, heat-resisting, strong adhesion, can satisfy the chimney anticorrosion requirement fully.
