Along with the development of stone conservation engineering practice, maintenance technology greatly enriched. Maintenance theory also emerge in endlessly. All sorts of theories are based on the practice of maintenance of all kinds of problems and the analysis of the phenomenon and solutions, has its rationality and suitability, also has its unilateralism and conditionality. In the recent stone conservation practice appear some new problems, form, and summarizes some new ideas are as follows.
A, not all Natural Stone material all need protection
If only is waterproof and alkali, hang in ten construction of some high hardness and high density stone material can not do protection. This also applies to some of the coarse grain granite. For instance in igneous rock is cold and get slow zhongtong thick flower of magmatic rocks, large chunks of quartz very much, this is very low density of the surface water and some other quartz pollutants are in. Not penetrate This theory has the international stone association maintenance Maurizio experts the seal of and identity. What kind of material need protection play what stone don't need to test method is in polishing marble surface water in granite under or polishing surface vinegar, 5 min drop if dry spot after without water or vinegar residue, the spot varieties marble or granite won't do protection.
Second, stone material protection to the material condition, for material construction
In engineering practice will find protective agent for some kinds of stone material protection the effect not beautiful. Exclude construction undeserved and production failure, most likely reason is not the correct stone chemicals for protection. Such as granite and marble because its mineral composition and chemical composition of different, with the formula of the agent is not the same. Even though the same categories of stone material, because density and chemical composition and different increase or reduce the concentration of organic silicon resin. Such as protective agent sandstone in the concentration of organic silicon resin will be higher, hardness and the high density granite or marble protective agent silicone resin concentration will lower. So in stone conservation construction material condition, but by certain material construction. According to different with different chemicals and stone different construction process. This also more illustrates the necessity of a stone conservation database. Like a stone conservation foot compiled a dictionary or an encyclopedia. In the maintenance before construction by referring to choose the correct chemicals and construction methods, biz, not only can effect is remarkable, still can save the cost of.
Three, not blindly import stone conservation product also superstition on domestic maintenance products don't bias
At present foreign brand of maintenance product is generally regarded as the symbol of high quality. But the high prices affect foreign brand promotion. Domestic brand of maintenance products are the underdog, but because of its low price fall also has certain market share.
Actually these prejudices of stone conservation knowledge comes from the don't understand. All of the protective agent import and domestic no matter by effective components and thinner and additives form. This door and homebred makes no difference. In recent years, domestic stone/protective agent product research and development and application development soon, in organic silicon manufacturing and resin monomer synthesis field has been close to the foreign advanced water. In complex process and abroad with considerable. In the construction application field is ahead in abroad.
The engineering practice shows that the case if foreign protection product improper selection can also cause the failure to the owner, maintenance of the losses. For example have three foreign brands protection agent in the application in high density, high hardness granite happen when dark phenomenon. If the application will also have the clear light face the surface residue. If choose the price higher powerful infiltration organic fluorine silicon protective agent will not appear afore-mentioned problems. And cause surface residue, white spot or the cause of the dark mostly because of the improper protective agent selection.
The correct view is stone material protective agent should not to "import or with production, the price is high or low" as the standard of quality stand or fall judgment. And should see whether you choose the right products for the appropriate engineering practice. Some engineering choose some protective agent effect very good, may is just a Chinese brand, price cheap, this means to choose. Some engineering took some protection product poor results, the price is very high, may is just a foreign brands. This only shows that the existence of protection product choice appropriate or not appropriate.
Four, natural stone floor shop is not smooth stone material selection by MAO surface make level renovation, then artificial stone conservation
Now the floor shop outfit is choose good smooth stone pavement directly, and then also make level renovation, equal to repeat the polishing process, cost is higher. Accurate method is to choose a good smooth stone effect, to buy hair surface specification board, then shop outfit, make level, renovation and maintenance. This can greatly reduce the cost. This method in overseas is already used in engineering practice, has not formed in China, mainly is applied to consumers and construction enterprise form stone disjointed, in concept not consistent. High costs by consumers bear completely.
Although many advantages, but this approach only suitable for color general lesser, not the texture of granite stone, for a lot of texture with marble, because there is a layout problem, so should still using traditional methods to do, in good design, and then continue the construction.
Interior decoration stone because do not the sun, and the wind by acid rain, snow, fog frost effects. So the protective effect continues for a long time. The service life of protective chemical influence is relatively minor. From reduce indoor decoration pollution and reduce cost Angle consideration, can choose low-cost water protective agent. But the kitchen and bath wait between the destructive strong environmental suggest using solvent protective agent.
Five, the rusty spot and spitting yellow, do not want to distinguish all the simple processing studied
Many of the stone when there was mistaken for a rusty spot macular pucker. Rusty spot contain iron, use commonly studied can get rid of. And macular cause has two kinds commonly, easy and rusty spot confusion. One is wet stick and stone material, cement filling the organic additive through the underside wool stoma to surface in water permeability, organic ingredients of a double oxygen conditions fracture, the color yellow. This is the case in wet stick and filling white hemp stone material is more common. Still have a kind of a situation is cream-colored, because of marble alkali spot to absorb the surface layer, change gesso produce gel light makes alkali spot after dark, as if a more "yellow", it is actually the gel layer containing gesso in time, so to these causes of macular, not simple to use studied to solve. To suit the remedy to the case, otherwise will probably the worse the processing.
China stone market-along with the development of stone conservation engineering practice, maintenance technology greatly enriched. Maintenance theory also emerge in endlessly.
