Abstract
The invention provides a double-layer anti-corrosion system applied to a wet chimney and relates to the field of fireproof and anti-corrosion materials. The double-layer anti-corrosion system applied to the wet chimney comprises a chimney outer wall body, wherein the inner surface of the outer wall body is coated with a layer of perchloroethylene anti-corrosion priming paint, the thickness of the priming paint is 10-15 mm, the priming paint is coated with a layer of acrylic acid waterproof glue, and the waterproof glue is bonded with vitrification ceramic tile layers. The vitrification ceramic tile layers are distributed in an inner layer and an outer layer, the vitrification ceramic tile in the inner layer and the vitrification ceramic tile in the outer layer are distributed in a staggered way, the thickness of the vitrification ceramic tiles on the outer layer is three fourths that of the vitrification ceramic tiles on the inner layer, the intervals among the vitrification ceramic tiles are filled with polyurethane sealant and silicone rubber class high-temperature elastic bonding sealing materials, and the surfaces of the vitrification ceramic tiles on the outer layer are coated with an anti-corrosion and acid-resistant layer. Deformation stress is reduced through a stainless steel grid layer, the service life is largely prolonged, the anti-corrosion and acid-resistant effect is two to three times that in the prior art, the manufacturing cost is reduced by 30 percent, the double-layer anti-corrosion system applied to the wet chimney is convenient to maintain and replace, and the chimney outer wall body does not need to be replaced.
Description
Technical field
The present invention relates to fire-resistant anti-corrosion material field, particularly relate to Wet chimney corrosion protection system.
Background technology
The anticorrosion general employing of Wet chimney inner surface of prior art simply applies the coating of anticorrosion acid-proof, in chimney long term high temperature peracid corrosion under, exterior wall can due to high temperature local distortion, thus cause coating at part became uneven, antiseptic effect reduces, thus corrosion exterior wall, cause exterior wall to peel off, shorten physical life, and it is higher directly to apply the resistant to elevated temperatures characteristic requirements of coating to coating, cost of manufacture increases greatly, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of high temperature resistant, corrosion-resistant, structure is simple, cost of manufacture low for Wet chimney double layer anticorrosive system.
For realizing the object of the invention, provide following technical scheme: a kind of for Wet chimney double layer anticorrosive system, comprise chimney exterior wall, it is characterized in that described exterior wall inner surface is coated with and be brushed with one deck chlorinated polyvinyl chloride anti-corrosion primer, described base coat thickness is 10 ~ 15mm, described priming paint is coated with one deck polyacrylic water-proof glue, marine glue is pasted with vitreous ceramic brick layer, described vitreous ceramic brick layer is set to inside and outside two-layer, between ectonexine, each vitreous ceramic brick is staggered, outer vitreous ceramic brick thickness is 3/4 of internal layer vitreous ceramic brick thickness, in described each piece of vitreous ceramic brick gap, all pouring has polyurethane sealant and silicone rubber kinds high temperature elastomeric to be bonded and sealed material, described outer vitreous ceramic brick surface is coated with the anticorrosion acid-resistant layer of one deck.By arranging double-deck vitreous ceramic brick layer, and inside and outside two layers of thickness is successively decreased,
As preferably, have additional one deck stainless (steel) wire compartment between exterior wall and priming paint, in described Stainless steel mesh, be cast with concrete.Described Stainless steel mesh aperture is 5 ~ 8mm.
Beneficial effect of the present invention: the present invention is by setting up double-deck vitreous ceramic brick layer at chimney inner surface; effectively prevent high temperature deformation; and by stainless (steel) wire compartment Reducing distortion stress; substantially prolongs application life; its corrosion resistant acid-proof effect is 2 ~ 3 times of prior art; cost of manufacture reduces 30%, and is convenient to maintain and replace, without the need to changing chimney exterior wall.
