With the development and progress of science and technology , advanced stone architecture and decor have been non- Emperor , the nobility of patents . Today, the stone has become widely used in building decoration materials, in addition to durable outside its unique luster, color , and texture can make buildings to add one gorgeous, noble temperament.
Stone Although durable, but still natural weathering and aging, stone floors and stairs more damage because of friction , losing itself should be valuable . So, stone care has become a property management , cleaning professionals required courses .
Stone Care must first understand the characteristics of the stone :
There are stone Artificial stone with natural stone of the points.
Common artificial stone with ceramic stone , tiles and porcelain tiles .
Microcrystalline stone through the base glass and inorganic material in the process is heated to 1200 degrees , control is made of crystallization , by the combination of wollastonite and glass crystal containing a large number of overall crystalline and vitreous materials glossiness 90-120 degrees.
Tiles are made of clay and stone powder compaction and sintering molding, surface treatment and then after polishing and grinding , surface gloss at 65 degrees.
Tiles is greater pressure and higher firing temperature , made of porcelain tiles , surface gloss at 80 degrees.
A wide range of natural stone , has documented more than 1000 kinds , according to the chemical composition and crystal structure is divided into two major types of marble and granite .
Marble is greater than 50% carbonate minerals containing metamorphic and sedimentary rocks , mainly by its original rock carbonate ions and metal cations compound which consists of rock salt mineral composition , visual texture patterns NCKU area , it crystal density , high compressive strength (100-200Mpa), but the hardness is not large (S.H40-50), do not wear, easy to aging , marble strict distinction , can be summarized as microcrystalline marble marble and crystal grains two categories, crystal diameter greater than 0.5mm called coarse-grained ( grain crystal ) , the crystal diameter less than 0.5mm called microcrystalline ( Xu Jing ) .
Most precious marble from microcrystalline marble series, common are: White Jazz , Golden beige , orange red , cream red, brown mesh , black and white roots . After careful microcrystalline marble polished crystal hard handling and quality , gloss up to 100 degrees.
Grain crystal marble common: white marble , beige Spain , Italy big flower green , gray clouds , Brazil rose red , black jade and so on. Grain hardness than microcrystalline grain marble marble and higher than wearable, but somewhat less gloss than microcrystalline marble , polished and quality through meticulous hard crystalline processing , gloss up to 70-90 degrees , tablets crystal marble more reasonable care should be taken , otherwise, the surface grain off and form a distinct convex surface .
Granite granite known , are igneous , derived from the granite, visual patterns into small pieces , the main ingredient is silica , representing more than 60% of the total composition of stone , mainly composed of quartz ( crystalline silica ) , mica, feldspar , whose original rock is dominated by silicic acid anions and metal cations made silicon-carbon compound mineral composition of rock salt , granite crystal thick and dense , high compressive strength (120-300Mpa), hardness (S. H75-110), high-quality granite and crystal hard by careful treatment , gloss up to 110-120 degrees , but the drawback is that it is inevitable that a small recessed pitting. Although granite dense structure , low water absorption ( 0.1% -0.7% ) , but it belongs to acid rock , hydrophilic , so the granite floor after washing , stone on stone engagement between the place will be significant water marks . Granite can be summarized as grain grained granite and floc grained granite into two categories, the construction industry tend to incorporate a number of sandy sediments among marble class , but standing property management and maintenance point of view , should go into the granite , sandy common sedimentary rocks are: crystal white , white sand stone, wood red, green and other domestic large flowers .
Common grain grained granite are: large gray , Indian red , Sichuan red , evergreen, brown diamonds , black and so on Sands .
Grain grained granite quartz crystal is very hard, but softer feldspar crystals , coupled with mica formed pitting, if there is no reasonable maintenance, quickly becomes uneven, and even become burlap stone.
Common floc grained granite are: spray white, tiger yellow , magic rainbow, Pteris red, watercolor red , hot springs and green .
Xu Jing had a granite hard granite and marble , the colorful, after careful grinding and polishing will be fine after a dimple , rounded concave , so that the ground distance, showing bright and clear , close look slightly hazy, to people a romantic mood . Xu Jing uneven granite quartz , quartz fewer parts more easy to wear, if there is no reasonable maintenance, stone face will soon become irregular wavy .
