Problems solved by technology

Because the granite structure itself has a certain water absorption rate (generally 0.15-0.4%), when it is in a chemical medium environment, a small amount of its mineral components are dissolved in acid, which increases the porosity of the granite (the porosity of the granite itself is generally 0.3-0.7%), so that the environmental chemical medium will penetrate into the concrete layer through the pores of the granite, affecting the anti-corrosion effect

Embodiment 1

[0021] Immerse the granite in 20.0% industrial hydrochloric acid until no air bubbles appear on the surface, put it into a clear water pool to dissolve the soluble matter, rinse it with clean water, check for no acid, no reaction and water soluble matter, and dry it at room temperature for later use.

[0022] The above treated granite was dipped in high chlorinated polyethylene varnish for soaking. After the voids are completely filled, take out the resin liquid that cleans the surface of the granite to make the material surface even and smooth, and check the filling density of the resin after drying. In order to completely immerse the resin without leaving gaps, this process can be repeated 1-2 times.

[0023] Paste the treated granite according to the construction process in the attached drawing (2) of the manual.

Embodiment 2

[0025] Immerse the granite in 15.0% industrial sulfuric acid and 5.0% acetic acid until no air bubbles appear on the surface, put it into a clear water pool to dissolve soluble matter, rinse with clean water, check for no acid, no reaction and water soluble matter, and dry at 105°C spare.

[0026] Dip the above treated granite into an acrylic varnish for soaking. After the voids are completely filled, take out the resin liquid that cleans the surface of the granite to make the material surface even and smooth, and check the filling density of the resin after drying. In order to completely immerse the resin without leaving gaps, this process can be repeated 1-2 times.

[0027] Paste the treated granite according to the construction process in the attached drawing (2) of the manual.

Abstract

The invention discloses a granite base material used for preventing corrosion and protecting the veneering. A little of mineral components in the granite base material is reacted with acid, dissolved, washed and dried by acid dipping and washing, then proper antiseptic varnish is selected for carrying out dipping to fill in the porosity of the granite. The processed granite employs a double-layer schindylesis-displaced binding method to ensure that environmental chemical media can not enter the concrete layer, thus enhancing the corrosion resistant capacity of the concrete.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion technology for concrete surfaces of industrial buildings, in particular to a processing method and construction technology for anti-corrosion of industrial buildings using granite with high corrosion resistance. Background technique [0002] Granite is composed of feldspar and quartz doped with a small amount of mica and trace minerals, such as: zircon, ilmenite titanite, magnetite, apatite, calcite, dolomite, magnesite, etc. The characteristics of this kind of chemical substance, its material is convenient, low cost, easy construction; high hardness, no trace after scratching, uniform and beautiful texture, etc., has been widely used in the anticorrosion engineering of the anticorrosion concrete surface of general buildings and industrial buildings . Because the granite structure itself has a certain water absorption rate (generally 0.15-0.4%), when it is in a chemical medium environment,...
