The basic way of stone conservation and application1

Core tip: stone is a kind of don't need to maintain the durability of the material? No! Because of stone material itself has a prominent physical characteristics (water imbibition General granite bibulous rate at 0. 1% - 0. 2) 。 Stone is a kind of don't need to maintain the durability of the material? No! Because of stone material itself has a prominent physical characteristics (water imbibition General granite bibulous rate at 0. 1% - 0. 2) 。 Due to unreasonable stacking, packing, transportation, and external pollution sources, such as moisture, rain, such as oil and its contact, stone material is susceptible to pollution. Users often encounter the problem of pollution are: whiskering, rusty spot, spit yellow, blotch, oil stain, straw rope yellow and weathering, aging, fade in color, luster and wear. In addition, and construction personnel often encountered in the construction of water after a stone wet stick construction spot not problem phenomenon of watermark, is one of the engineering main reason for the dispute. Stone conservation cleaning and protection are two main points, main protection principle is effective in protecting agent with solvent entering into stone inside, after being natural volatile solvent, effective substances and stone crystal, as a effective protective barrier under the stone material surface, to prevent the external and internal contamination of infiltration, to protect the stone, extend the life of the stone. For protection of stone, after the bibulous rate is greatly reduced, almost no water; As long as water infiltration into stone, also will not produce pollution. After the protection of stone material has the following characteristics: waterproof, anti-fouling, resistance to ultraviolet radiation ( Delay the stone fade time) Resistance, frost resistance, solubility, keep the stone material permeability, and can reduce the difficulty of daily maintenance. Protective construction ways mainly divided into two kinds, one kind is stone construction before protection, is a kind of stone material after construction for protection. Stone conservation treatment method in general is very simple, do not need special tools. Some engineers might ask, what is now with the wax in the hotel? Wax is used in the hotel industry in our country at present most of a way to maintain stone ground, can say it is also a kind of wrong maintenance method. Why is that? Because of wax is an airtight sealant, after the wax, although it can't go into the water and moisture inside the stone material, can be in a certain extent, prevent pollution, but the stone and internal moisture, below couldn't send out because of the effect of sealing wax, so that water vapor long-term accumulated inside the stone, will cause the stone lesions; Wax and generally affect the natural color stone, at the same time often waxing might damage the stone surface, shorten stone material life. So now do not use in Europe and the United States developed countries basically wax to maintain stone material, but with stone curing agent.
