Diseases and maintenance of stone
In recent years, due to the deterioration of the natural environment, dust, industrial waste gas and steam turbine   exhaust gases, acid rain and other pollutants, building stone used on vulnerable to pollution. Once the building stone was polluted, cleaning very easy. Harbin maintains cleanliness the company considered poor if you use cleaning agents, stain removal by force, extremely easy to damage stone, accelerated deterioration of the stone. A modern building, in addition to the structure design, overall appearance of maintenance should not be neglected. Within domestic stone for building external wall decoration is becoming increasingly common and for stone conservation projects are increasingly causing architects, construction companies and owner of attention.
In General often encounter problems: stone water seepage on external walls, Rainbow, dust, stains, water spots, oil pollution and weathering, aging spots, construction materials, and gloss and wear caused by access, and so on. To solve these problems, stone conservation, Harbin offers the following several kinds of treatment and preventive maintenance method, for your reference.
, Stone water seepage on outer wall and pollution treatment:
Due to building among key Government, relatively pollution is particularly serious.
Due to stone itself has hair fine hole and the absorbent, air pollution, dust plus air in the of acid gas, steam locomotive of exhaust,, tip to attached Yu stone surface, dang rain of when, acid rain will accelerated these pollution on stone of erosion and adsorption in stone of hair fine hole within, caused easily cleaning of dirt spot, especially for fire surface of stone for, these pollution formed of speed faster, and not easy cleaning, only using city sale of cleaning agent fundamental cannot removal these pollution; if smooth of stone, The gloss was quickly eroded away. Therefore, to remove the pollution, you can use special cleaning agent for stone, this kind of stone cleaning agents can penetrate the pores in the complete removal of pollution and does not damage stones. If to prevent stone again once was pollution words, can Yu stone cleaning clean Hou, in stone surface dry of case Xia, again for a protection processing of work, this permeability of protection agent common of has United States thought Kang stone protection agent, this species protection agent can into stone internal, formed a protection layer, has waterproof, and anti-dirt, and rust spot, and anti-oil, and wind of, and anti-aging, and acid alkali, and anti-tea stains, and Coke, and soy sauce, caused of dirt spot of effect, and can effective control rainbow of produced, and not loss and the stone original of breathable sex , Only water to clean normal cleaning effect can be achieved without the use of other cleaning agents.
Exterior pollution treatment in advance:
In General, the stone walls of considerable height, cause pollution and then to clean, construction is extremely inconvenient. If prior can do protection processing words, completed Hou will no pollution Shang of problem, daily of cleaning work also just with water wipe can, and construction Qian of protection processing cost lower, and construction more easy, and compared by stone protection agent, this revolutionary of breakthrough improved has past protection processing time-consuming effort of troubled, currently this workers method in abroad has was widely application in stone engineering Shang.
