The application of sandstone and protection knowledge

Many people think that the Sandstone is hard stone, they don't need maintenance nursing care. That is not the case. Want to keep the beautiful appearance, the luster of sandstone, texture and practical, must know the characteristics of sandstone, and take special care measures.
1. The sandstone profile
sandstone block (also called sand rock) is a kind of sedimentary rocks, and sand by a named, its main component is Si20, Al20,, in nature is through the sea change to geological sedimentary and land to the original sedimentary, a large accumulation of sand layer of terrain, and after the cover in the process of geologic change heating, pressure and form.
Natural sandstone points sea sandstone and mud sandstone two kinds, the sea of sandstone grain is thick, hardness, space than mud sandstone hard rate is bigger, brittle, main representative varieties are hard sandstone, Spain sandstone, Australia And mud is exquisite, hardness is a little sandstone soft sea sandstone. In addition, there is a kind of natural sandstone material for female inorganic powder ZhuZhi with a synthetic sandstone, such as TaoLiKe sandstone aubstadt, the sandstone.
2. Sandstone Slab in architectural decoration application and advantages
2.1 sandstone in architectural decoration application
In recent years, as construction decoration to go green health, texture flowery, advocating natural new consumption concept of development, both health and environmental protection are highly ornamental sandstone, in adornment the stone material of a popular qiao, alone. Can be widely used in external decoration, floor, the door is covered,, furniture, baluster, headstones, courtyard stone, sculpture art.
2.2 the superiority of the Sandstone Tile
From the adornment sex in terms of sandstone simple and easy, straightforward, natural; Decorative pattern change in nature, like the strange tree-ring, lumber decorative pattern, landscape painting; Very simple but elegant, sweet, and do not break showily atmosphere, can give a person with return uncut jade to return true, close to the wild feeling; In addition has good compression, wear-resisting characteristic, is the metope, ground adornment and good varieties profile.
From environmental protection sex in terms of sandstone is a kind of inferior smooth stone, won't produce light for, in the form of light pollution, it is a kind of natural antiskid material. And marble, granite is smooth stone material, it is only through light to show adornment effect, easy to produce the light with a deficit.
Because of its internal structure sandstone rate the characteristics of large space, with sound absorption, moisture absorption, fire prevention, matt properties, such as the nature of this breed adornment to have the absorption requirements of the cinema, stadium, and public places such as hotel is very ideal effect.
The sandstone is zero radioactivity stone material, no damage to the human body. Marble, granite in trace radioactive, live for a long time in which to person will be subjected to the damage. Our country "building material radionuclide set limit to" (GB6165-2001) to make clear a regulation, the sandstone radioactive is not included in the scope of radioactive inspection, it is based on many years of monitoring, and the standard of the great selective examination to the conclusion. In fact, as a kind of to Si O, A1 O, give priority to stone material, it is itself a kind of environmental protection, green, with the trust of building materials.
From the durability in terms of sandstone outdoor not weathering, the water not melt, and not long lichen, will not change color. Many in the one thousand two hundred years before the building was built in sandstone cult-favorite charm, since late February.
3. Sandstone products with protection
Dirt are not only beautiful and contain let sandstone metamorphic erosive chemical composition. To prevent pollution metamorphism, facilitate scrubbed, prevent water permeability or in order to make the sandstone more bright-coloured, can use besmear brushs protective agent method. On the market at present is the product of the agent that have very DuoZhong protection, respectively, are used in different stone material. Use of protective agent must be considered when the stone material and its adequate adhesiveness (sometimes sparkling), whether with stone material, protective agent climate around react. Protective agent to the using solvent can be divided into acrylic emulsion of water), and (silicon and solvent (chemical) 3 kinds. Silicon-based protective agent compared, solvent protective agent, water protective agent on the colour less effect.
3.1 indoor protection agent
Sandstone granularity for solid, the atmosphere is good, must keep their some degree of breathing freedom. Usually, indoor humidity is stable, not easy to be the weather, the changes in temperature and the influence of damp. So, generally no expansion. Therefore, indoor basically can choose any type of protective agent. It should be noted, protective agent after a period when asked to use must besmear brushs, this same with paint.
At the same time in indoor use of protective agent must think ahead to the following some situation: whether to wash, prevent wear, prevent wipe the surface by food or oily be soiled pollution, facilitate repeated besmear brushs and so on.
3.2 outdoor protection agent
Outdoor use of protective agent should pay attention to many matters, in a formal before besmear brushs should be fully consider the following environment:
If placed in the sand and gravel sandstone, sand and gravel on because of the high rate of water conservation, had better not use protective agent.
If the stone placed in cement in structure, should choose to make a small stone keep breath (namely moisture permeability to stones and through the steam of protective agent, volatile) it is important. Usually, water-based acrylic emulsion (protection) agents in outdoor effect become more prominent.
Outdoor use protective agent should have the advantages of easy to clean, can freely use hose or washing machine, and high pressure wash brush, polishing, processing, and also can fade and besmirch to natural bleach.
3.3 sandstone products stored and maintenance
Dirt and infected with not only beautiful, but also let anything bad aggressive sandstone chemical composition. Pollution is during the construction or maintenance produced during, must be treated differently. In general prevention is more important than cleaning, daily long-term maintenance effect better than the axon acute cleaning. Can the right design and material selection, be careful construction and maintenance to reduce and prevent dirt stain. The so-called right design, namely attention the following things happened to sandstone products of the pollution:
Products on graphics processing, foreign tilted wall cap rocks, use wall cave drainage didn't ask part, water flows into the structure of the narrow place of water flow through the concrete, glass, or other building materials surface and flow to sandstone extremely easily to the surface of sandstone products cause pollution. In the special environment, should choose and stone material properties of materials to match. For example, as a walls lined with use, must on the elevator up near the positive and switch, the furniture and so on to protection. Not compatible with material combination between easy to have the pollution. (for example, the bus to the leakage of liquid sandstone.) Laying on the bridge or steps, the permeability of the mortar will become coal sex pollution. The wrong cleaning process after the juncture is one of the important reasons.
The correct processing measures include careful attention to transportation, storage, construction and so on various links. The panels of the thin not only vulnerable, and very easy to crisp stained with besmirch. Must pay attention to the mortar, the coating, the protective layer stains, scaffold point rust and mechanical lubricating oil etc resistant stain.
From the end of the shelf life of construction, the stone material must as far as possible during with plastic layer or cloth cover cover antifouling.
Thoroughly understand the service process may be due to pollution caused by human body contact or the internal and external pollution. As far as possible and pollution sources must be quarantined, often eliminate dirt, etc. In the pollution area, using appropriate paint cleaner and architectural stain. Of stone material for cleaning, should be moderate, prevent to environment and homework personnel to produce harm to cause loss or stone material itself. Consider the cost factor, cleaning should economic and effective. Therefore, must be familiar with the following matters:
1) clean convenient way and the place;
2) when cleaning of stone material cause of the loss of feeling ability;
3) surface level of pollution;
4) if they must be clean.
3.3 sandstone of mesa protection
Each stone have their own weakness, but the sandstone a weakness is porous. This porous structure makes easy penetration in water. Once the sandstone absorbed moisture will lead to change color and chemical coloring. These spots will become an integral part of sandstone. Therefore, the sandstone need special care.
Do not use any type of cleaner or clean technology. Improper use cleaner can lead to serious consequences. Therefore, in the use, test before you check the label on the cleaner. If you find some adverse reaction to immediately stop using it.
If sandstone mesa already sealed, can use a few simple cleaning method to protect it. Seal is very important protection steps. A seal sustainable for many years. In the use of sandstone mesa should special care.
Cleared the spill. Do not let its long legacy in sandstone mesa. Clean sandstone mesa should choose when neutral cleaner or colorless, odorless and detergents. May choose to use a mild dishwashing liquid. Do not use acidic cleaner. Will this cleaning fluid corrosion sandstone polishing face.
Often flush sandstone mesa and grouting place. Don't put the cleaner in sandstone mesa. If no prior clean soft hair brush to brush off scraps can be used. If besmirch brush away, don't scrape. Can repeat clean.
An occasional deep clean. Deep clean also need to use neutral cleaner. Can buy designed for deep clean design cleaning tools. Soft brush remove stubborn available waste. Cleaner sprinkle don't immediately after them. Finally thoroughly flush mesa, the step is very important.
Sandstone of mesa protection note the following Suggestions:
1) sandstone cleaner must be neutral.
2) cleaners can't contain acid or citrus acid. These components can damage of the surface gloss of sandstone.
3) use with metal accessories vacuum cleaner carefully. These accessories can scratch sandstone surface.
4) never try scrub powder or scrub cream, these products contain scratch sandstone abrasive surface.
5) avoid using the glass in the tray.
6) don't put the high temperature vessels placed into the sandstone directly on mesa. Best cushion pad.
