1 Facade technical analysis of stone

1.1 Classification of Stone

Facade is generally divided into the natural granite stone, natural marble, artificial stone three categories. Natural granite is igneous rock, its fine structure, showing both the overall granular structure. According to the size of crystalline particles often divided into "pegmatite", "coarse grain", "fine grain" of three. Its color is usually gray, red, rose-color or red, gray and white colors, polished in the process, they form a beautiful color and different shades of speckled pattern, the pattern is characterized by fine grain size uniformity, and distributed like the stars bright and glittering mica, quartz crystal. Natural marble is recrystallized Limestone, and its main component is calcium and dolomite, mineral grains more. Marble poor crystallinity, the surface was a circle shape, vein pattern shape or branches. Non-natural man-made stone, by the resin, cement and gravel mixture is made adhesives.

1.2 The principle of selection of stone

(1) from the construction costs to consider. Different stone (mainly natural stone) because of its quality, quantity, mining areas, processing methods, such as different, the price will also have significant differences. Therefore, real estate investors and designers in the initial selection, the project should consider the overall economic accounting, cost control due to its considerable degree of control.

Laser cleaning of stone to new nursing program

With the high accuracy of the cleaning of stone have become increasingly demanding, and human environmental awareness, laser cleaning technology as a new cleaning method is being recognized and development. Laser cleaning technology mainly to high-speed laser beam to be cleaned effectively clean the surface of the attachment, it saves time, effort, water, and safe, reliable, wide application, easy to automatic control. Especially for stone carving, stone carving, stone face a variety of corners and other fine structure, and the age-old stone artifacts and other high stone cleaning, laser cleaning technology is that many traditional cleaning process can not be compared. Therefore, we can say that laser cleaning is a major advance in cleaning technology, promote the use of laser cleaning technology will make the stone even more powerful cleaning industry. From the surface; third dirt molecules will evaporate in an instant, gasification or decomposition. Laser cleaning technology is the use of laser pulses of vibration, thermal expansion and molecular particles of light the role of decomposition or phase change, or their three joint action to overcome the dirt and the matrix material bonding between the Slate, away from the surface to achieve cleaning purposes.

Matrix according to washing the optical properties of the material and dirt analysis, but also the mechanisms of laser cleaning is divided into two categories: one is the use of substrate material and surface adhesion of dirt on a wavelength of laser energy absorption coefficient difference between the laser full of energy absorbed by the dirt attached to thermal expansion or vaporization of volatile and is vaporized to form steam flow driven out of the matrix material to achieve the goal of cleaning, which countertop the matrix material on laser energy absorption coefficient is small.

Q dirt and stone surface of the main binding force of physical force and the weak chemical interactions. Weak chemical interactions, including the formation of hydrogen bonds and charge transfer bond energy and other physical forces, including van der Waals forces (including electrostatic, induction and dispersion) and the capillary force and so on. More difficult than other surface materials, stone cleaning is due to the existence of a large natural stone micro-pores, micro-pore capillary force dirt and stone not only between the various binding is enhanced, while its role so that all parcels kinds of cleaning the external hard work.

Laser is a very good color and direction of light radiation. Combination of focused beam through the mirror, the beam focused to a small area or region. Laser beam can produce at least three roles: First, the solid surface in the mechanical resonance phenomenon that cracked off the surface or coagulation; Second, the surface scale layer will overcome by the expansion of dirt particles in the matrix material on the adhesive force and they are not damaged, so the key to achieving safe and efficient cleaning is to choose the appropriate laser wavelength and to control moderate energy density. The other is the surface of the substrate material and attachment of the absorption coefficient of the laser beam is not very different, or heat the surface of attachment will produce toxic substances, etc. are usually used to clean high power pulsed laser frequency and the impact to be cleaned surface, so that part of the beam into sound waves, sound waves after the impact of hard surfaces in the lower back, the return portion of incident laser wave generated by the interference, resulting in high-energy resonant wave, so that small scale layer burst occurred, resulting in crushing, easy-to- material from the substrate surface.

For more than stone surface dirt cleaning mechanism is often combined use. Normally be processed according to the case of stone and dirt section of the frequency of laser pulses per second (0.5 to 30 pulses) and amplitude (8 to 25ns), so that the appropriate material absorbs light dirt. The frequency of the laser pulse repetition allows the impact of the role of porous stone surfaces and loose dirt Ko gap, when the laser is greater than the impact of substrate on the adsorption force dirt particles, dirt particles from the substrate to be cleaned purposes. When the laser photon energy is greater than (adhesion layer) dirt molecular bond energy, the laser photolysis, light exfoliation have to play effects, such as KrF excimer laser photon energy 5eV, greater than the organic dirt OO, HH, OH, CC, CH and NH chemical bonds such as bond energy, the laser can damage parts of the role of chemical bonds, decomposition of organic matter, which can be cleaned of organic oil. When the laser beam energy density further increases, a number of inorganic dirt. Such as those containing K, Na salt and the light from the decomposition of organic dirt and inorganic substances can be produced by expansion of laser heating to generate thermal stripping (ie, stripped of light) and from the substrate surface. To take full advantage of the various LASER role in strengthening the laser cleaning effect, often in advance on the surface of the substrate to be cleaned artificially put on some water or water mixed with methanol or ethanol liquid. When the laser light hits the film on, the liquid film due to rapid heating, will produce explosive vaporization, the explosion that loose dirt surface of the substrate and the substrate with surface wave departed, to the purpose of Mosaic. In this approach, although there are dirt particles in the particle vibration and thermal expansion, but the role of the explosive shock wave is the main, this method is also known as laser + film method in the matrix covered the surface of the liquid film thickness is 10 / m .

How to clean marble cabinets than good

Conservation

Marble more pores, it is easy with dirt. If something spilled on the marble surface of the cabinet, should immediately wipe clean. Beverage bottles can be sent to something under arms to prevent the liquid stained marble desktop.

Regular cleaning

Occasionally wash with warm water marble cabinet surface and wipe dry with a clean cloth. Marble with a damp cloth to wipe the surface of cotton will not leave scratches. According to cleanliness, once or twice a year, with a mild detergent solution (hand dishwashing detergent and warm water) Rinse and dry.

As a coat of wax to protect the surface of the marble cabinet, but not very necessary. Use colorless wax. Do not wax white marble as it becomes yellow. Sealing can be applied to clean marble, marble stain will not be protected, and when the dust wipe with a damp cloth.

Special cleaning

If the surface of the marble cabinet lost its luster, you can use detergent and polishing marble, it means renewed glory. Purchased from a marble, the company has generally soft for the import of marble cleaner, so the hard marble the United States is very safe. Compared to the previous "marble cleaning tool", they work faster and easier.

Putty powder (tin oxide) can be used to wipe dust or broken cabinets marble surface with a damp cloth, the best use of electric grinding machine polishing. However, it has been difficult to find electric grinding machine. Serious damage, scratches or corrosion of the surface, can be used to make marble tombstone or other products.

Teach you how to buy marble and granite

Marble, granite is known as decorative stone:

To 60 cm × 60  example:

1. Stone plate thickness should be uniform, not thinner than 1.5 cm, to quasi-square foot, must be a right angle, trimming to tidy, there should be no obvious mechanical pattern or burst edges.

2. Better brightness, surface without pitting, light intensity at least 80 degrees.

3. Surface pattern, pattern uniform, no significant noise, chromatic aberration to be basically the same.

4. The internal structure of closely not have cracks.

Maintenance of decorative stone:

1. To regular cleaning to keep the surface clean and wax polish on a regular basis, so that the stone surface has a new look.

2. To avoid any acid, alkali and other chemicals, direct contact with the surface, causing chemical reactions, resulting in color differences.

3. Try to avoid nailing directly soles, often rubbing the ground.

How to identify the raw material of quartz stone countertops

The original quartz stone dirt fancy wear, spent nearly two million yuan to build the whole cabinet, but, with a day table was infected with the stain. After testing, this quartz is defective, composition containing calcium carbonate.

"Golden September and silver October," the housing market pick up, but also led the renovation industry in full swing. In the cabinet industry, the competition is quite fierce countertops, quartz stone with its high hardness, resistance to the advantages of oil has attracted many consumers. However, the reporter found that the numerous quartz market price of confusion, lack of strong third-party supervision. Consumer Protection Committee to remind consumers to pay attention at the time of purchase rights.

Complaints】 【print quartz stone countertops milk

The Canton Road, Xiao Wang, who lives in last month bought a new house, get the key after the beginning of the decoration. His special attention to kitchen cabinets to create a whole. Xiao Wang former cabinet table with the man-made stone, hardness and poor, are afraid to cut things on the table, even if cautiously, or have cracks around very quickly, very susceptible to stains, a long time, the counter everywhere is spotted. This time, decoration, Xiao Wang determined to learn the lesson, choose a hard, dirt's surface.

Quartz stone countertops how to identify fish in adulteration of raw materials

To the building materials market have come full circle, Xiao Wang finally set the quartz stone countertops, price is 1280 yuan per meter. "Salesperson assured me that the high content of the quartz countertops, hardness hard, wear-resistant dirt is good."

The market a bit chaotic quartz countertops

According to the introduction salesperson, quartz stone countertops is very easy to take care of them, the stain is difficult to stay on top, "the same can be maintained like new." Table with a silver-gray beige cabinets, new kitchen looks very elegant. Sandstone tried the chopped chicken on the table, the table motionless. "Although it took nearly two million of money, but was really glad that they picked the right." Xiao Wang said.

Unfortunately, did not last long. Immediately after being admitted to fitting new houses Xiao Wang. Early the next day, he got up while cooking the milk side of the teeth, inattentive, milk boiling, the foam is throwing the whole table. Xiao Wang quickly with a rag and wiped the table, but the side walls near the stove does not rub. That night, Xiao Wang found this at the white blot, to stay in the gray on the table is very conspicuous. Xiao Wang salesperson thought the original "easy care" theory, be wiped out to comfort myself. Can not think, he exhausted all means, this beach stains no improvement, hand touch, seems to have with the table "integrate" the.

"You are poor quartz countertop, which contains calcium carbonate." A friend in the decorating industry, told Xiao Wang.

Natural stone countertops seamless market, "money "King Unlimited

As the leading experts on natural stone radiological safety announcement. Cabinets, luxury hotels, hotel table users will tend to do with natural stone countertops, natural stone texture for clear, natural, high-end luxury noble people are recognized, such as Hangzhou, Chongqing, Beijing, Guangzhou and other cities, and each year has nearly 50% ? plus, the original table will not be recognized natural causes first, radioactive elements, the second is due to the limited length of the middle of the table is very beautiful interface, but also in the interface produce oil, natural stone patterns now have a new technology more seamless connection ?? add a natural stone countertops new business opportunities.

Market value of the table, the table according to media reports spending 26.7 billion yuan in 2010, reaching 92.2 million square meters, of natural stone countertops at the current market share of nearly half of the total? About power 46.1 million square meters, 5 meters wide and long for each table 0. 6 m of about 3 square meter? can produce table tops is 15,730,000.

Teach you how to select good stone

A, tonal

Natural finishes stone except to consider the tonal choose, consider the function of the building. In household, sitting room and bedroom adornment appropriate chooses slant warm tonal, to show warmth, comfortable emotional appeal; And for the toilet, kitchen adornment appropriate chooses grain quietly elegant is tonal, clean slants cold to show clean sanitation.

Second, illuminative intention and environmental impact

Due to the use of natural finishes stone decoration parts is different, so choose stone type also different. Used for outdoor building decoration, need to withstand wind blowing rain water period insolation, granite because does not contain carbonate, bibulous rate is small, fight weathering ability, had better choose various types of granite stone; Used for hall ground adornment of facing stone, ask its physical and chemical properties stability, high mechanical strength, should first selection granite kind stone; Used for dado and household bedroom ground adornment, mechanical strength is a bit poor, appropriate chooses beautiful pattern of the marble.

Three, identify finishes stone material quality

Processed products facing stone material, its good quality from the following four aspects can't identify the;

(1) the view, namely macroscopic observation of stone material surface structure. Generally speaking, uniform fine material structure of the stone has exquisite qualitative feeling, for shi caizhi beautiful is tasted; Thick bead and differ the stone material of its exterior grain structure effect is poorer, mechanical properties and uneven, quality is a bit poor. In addition, natural stone material because of geological effects in which produce some fine often pulse, micro fracture, stone material in these areas most easily broken along, we should pay attention to eliminate. As for lack of edges more influence is beautiful, less Angle should be paid attention to when the choice especially.

(2) the volume, that amount of stone material specification, lest affect joining together, or cause after mosaics pattern, pattern, line deformation, effect decorates the effect.

(3) listen, namely, listen to the stone material percussion. Generally speaking, good quality, internal density uniform and no microscopic fissures, the chiming of stone ringing and euphonic; Conversely, if the stone exist microscopic fissure or fine veins or because weathering cause particles become loose, criterion knock voice is husky dumb.

(4) try, which USES a simple test methods to test stone of good quality. Usually in on the rear drop of stone material, such as ink small drops ink infiltration out four sanctions soon, namely, said stone internal particles is loose or existence microscopic cracks, stone material quality is bad; Conversely, if ink drips in tight, then explaining stone dense texture is good.

Tell you stone plate machine program

Stone mining. The mining of raw stone stone plate into artificially mining and blasting mining two kinds. And blasting mining and points of blasting mining and big micro blasting mining two kinds. Marble, along the coast of granite (soft) coast granite compared with artificially mining or micro often blasting mining, more solid granite (such as sichuan area) generally with the big blasting mining.

Stone material processing. Refers to the waste material mined boulders, generally with the diamond sawing solution on disk saw for marble, the process can also be used emery saw processing. If a defect, waste materials for processing, found that before the due process is one-time complete emery saws, until after processing defect detection it might be too late. After saw solution plank called wool board.

Stone plate and polishing. Polishing equipment for a variety of general use carborundum abrasive. Granite polishing, use commonly composite cemented emery grinding block (also called grinding head) in polishing, commonly # 1, # 2 and # 3, 4 #, # 5 and 0 #, a total of six kinds of grinding block, 1 # most coarse, # 5 is very fine, 0 # is excluding emery polishing cream. Process from # 1 to 5 commonly used last sequence, # 0 # polishing. Marble polishing, use commonly felt add wax add all sorts of different particle degree of finish in polishing emery fine powder.

Stone trimming. Stone tabula rasa (burnished plank called tabula rasa) through trimming machine cutting into required specification can be manufactured, sold. Through above process of stone processing, stone material can factory. Sometimes in the construction site of stone material on the site, such as processing need to change small, cutting Angle, this is usually use handheld cutting machine cutting processing. A special processing, such as some stone needs above stiletto, edge grinding etc, are generally use portable cutting machine, Angle mill for stone plate processing.
