Stone eight kinds of lesions resolve

First, rust stone disease of the rust
Formed from two aspects: First, the natural reaction. Because the composition of a substance in the stone house contain hematite and pyrite, which is oxidized iron minerals contact with the air to produce iron oxide (rust), the oozing through the pores of the stone; and second, because the stone in the mining , processing, transportation, installation, use and other process, the inevitable exposure to iron items, residual items stick these iron deposited in the stone surface to form a rust contamination after being oxidized. The key to prevention is the stone rust marks must be used before installing resin injection method so that the stone with waterproof function, in order to prevent the stone house after being oxidized iron minerals seeping stone surface. After installing the stone must be thoroughly cleaned to prevent contamination due to external stone rust marks. In terms of construction method using dry hanging way possible, especially as the United States white linen and other similar stone more prone to rust, but should avoid the use of wet construction method, if necessary, prior to installation do all the rust and water treatment . Processing has emerged rust marks, the main products at home and abroad are rust remover, rust agents should ideally have two conditions: first, after the stone material rust will not rust; secondly requirements Rust itself does not corrode Stone, does not affect the stone surface gloss. However, due to rust agents are acidic, so the dilution of marble (calcareous stone) in advance to do experiments rust necessary to add water. After blasting, wash thoroughly with water, then repellant for protection, so that the stone is waterproof to prevent future occurrence of other diseases and cumbersome due to chemical corrosion.
Second, the stone disease of the wet marks quit
The main reason is formed by wet construction methods due cement mortar. Because small amounts of trace elements contained in the cement composition of the adsorption of water is very strong, in a humid atmosphere when the ambient temperature is above 35 degrees, the solution has a corrosive form immediately. Crystal water often due to temperature changes, but never lack, which formed a wet marks quit phenomenon. Prevention method is mainly for protection of the stone so that the stone material with a waterproof, thus blocking contact with moisture in the air inside and stone or cement material, reducing its chemical reaction conditions; Secondly, we should try to avoid using cement construction and installation of the case material ; finally, a really good job caulk works and drainage works. Processing has emerged wet mark at home and abroad there is no effective way. Remedy is mainly used in the resin injection method makes no wet marks the site of the color deepened, thus adjusting the color difference between the two.
Third, the crystallization of salts of stone disease
This phenomenon is mainly due to the strong alkaline cement belonging to the atmosphere in the reaction from an acidic solution. Sodium carbonate solution was seeping through the pores of the stone surface of the stone, immediately and moisture-containing carbonic acid neutralization reaction of salt solution, after the solution of the water dried up, to form a salt crystallized. Dissolved water on a large area. Prevention First To avoid possible wet construction method, followed by the stone with waterproof protective agent. And earnestly caulk works. Salt crystallization process is relatively simple theme. First, a white powder with a brush to brush off the surface of the stone, and then thoroughly wash the residue with plenty of water, and finally protection or on the stone surface can be polished with a polishing agent with waterproof properties.
Fourth, the lime stone disease denudation
This phenomenon comes from the lime solution penetrate into the exterior surface, quickly, and carbon dioxide in the atmosphere to produce a substance hard to be hydrolyzed, permanent coating layer become one layer. This phenomenon occurs mainly in the stone seams. In dealing with lime erosion phenomenon, first with an acid solution to dissolve the calcium carbonate, then water thoroughly washed stone, and finally with waterproof resin injection, in order to stop leaking again lime solution.
Fifth, frost damage
Such phenomenon is mainly due to the stone inside the pores and cracks absorbed moisture due to freezing cold. Because the liquid water ice volume expansion of about 10%, so that the interior of the stone with great force and bursting stone. Some porous stone such situations are more likely. Preventive measures are the stone waterproof treatment to reduce the water content of the stone house.
Six moss plant growth
Phenomenon occurs mainly in the stone house water and organic matter content of the site, it will cause discoloration of stone, the stone of strength and service life reduced. Precautions must first make drainage works to avoid stagnant water; plus apply protectants, the stone has a good waterproof performance. Moss has appeared on the tool should be used to eradicate, and then professional cleaning agent, it is best to make protective treatment of stone, water and improve the existing drainage facilities.
Seven, chemical corrosion
This is due to industrial emissions at home coupled with vehicle emissions, the air of sulfur dioxide and sulfur trioxide content steep reasons. Dissolved in water to form an acidic solution, it can be easily dissolved in stone materials, causing chemical corrosion. Prevention is to do before construction stone waterproof, to prevent these harmful solution into the stone. In summary, the causes of these problems are all harmful ion solution caused by free access to the pores of the stone, in this process, the water becomes the carrier of hazardous substances and chemical reactions involved in the main role of harmful substances. So protective treatment of stone is the main water treatment.
