With the continuous development and progress of society, we have become increasingly demanding the use of stone. From the simple arc plate cylinder to a variety of shapes, from the the ordinary luminosity board to fire board, anti-ancient stone, illustrate With the improvements in technology of stone, the stone of an increasingly wide range of applications. If LCM thickness of the sheet called sheet, then we put the ultra-thin stone is defined as the sheet thickness 6mm. Technically simple to do thin is not difficult, difficult is that to do .. With the continuous development and progress of society, requirements for the use of stone getting higher and higher. From the simple arc plate cylinder to a variety of shapes, from the the ordinary luminosity board to fire board, anti-ancient stone, illustrate With the improvements in technology of stone, the stone of an increasingly wide range of applications.
If LCM thickness of the sheet called sheet, then we put the ultra-thin stone is defined as the sheet thickness 6mm. Thin technically simple to do, but not easy to do that is thin and bigger. So, we are here talking about the ultra-thin stone refers to the thickness of 6mm, size 400mm × 600mm. Some manufacturers claim to be able to do 1200mm × 2400mm × 3mm thin plate, in fact, this is unrealistic, because it is attached to a certain kind of backplane go to control thick, polished, this production process, at best, can only be called composite panels. Thin stone without any the back sticky material circumstances produced by the ultra-thin sheet. Therefore, we can make 600mm x 1800mm, presumably simple, of course, and then large size is also possible to do it, but it has lost its value in use, because everything must speak degrees. The value of the product is a cost factor. Therefore, we want to explore the development of ultra-thin stone a large-scale production, low-cost, high-quality ultra-thin stone to the building's exterior decoration is both a social benefits and economic benefits . Characteristics and the use of ultra-thin stone roughly:
1, load-bearing. 5mm thickness of the stone, the weight per square meter is 16kg plus paste, including the use of glue, nor higher than 20 kg. And if it is hanging stone, even with 2cm of stone, and steel keel, pendants, wall by focusing lOOkg / ㎡, ultra-thin stone paste method five times.
2 space. We know that hanging stone to pre-buried steel, cloth steel keel, stone pendant hang from the decorative surface of the stone to the wall normal distance 16 ~ 20cm paste thin plate just 1 ~ 2cm, even if uneven walls, find flat, but 3 ~ 4cm Where competent the hanging stone building locations are the high cost of land, so the significance of saving space.
3, time. Hanging stone embedded parts, cloth keel last hanging, each skilled workers the daily hanging area is only about 3 to 5 m, and a lot of air operations, on-site cutting, stone hanging difficult to multi-point, The multi-faceted operation, long construction period. And the the paste thin plate as paste tiles. Plaster, comb flat, tiling method is simple, the effect is the same, the average worker will teach several times per person per day to be completed by about lO m, due to the thin plate light, easy to operate, cutting, cutting tiles site mobile cutting machine can be field changed specifications, from the time of speaking, more than 2/3 complete with a project hanging stone time savings.
4, security. Many unused thin stone paste want to use the project, fearing paste not hanging firm, fall how to do? In addition to the amount of life? We will not say that the hanging of a nonconformity risks, is even qualified hanging, steel and plastic useful life of only 20 years, up to 30 years. The paste is non-alkali cement-based materials clay, paste it into the firmness of the wall far more than the tile, the useful life of over 30 years, almost the same period with the construction. Of course, we are here is qualified adhesives, with 5mm thin stone.
5, the cost. In theory, the stone, the thinner should be cheap. But on the contrary, thin stone to 1.2cm after monitoring critical point, and then after the thinner the more expensive, because the cost of the processing fee is greater than the prices of raw materials of stone, but a stone is thinner and cheaper, that is, in high-grade stone. Because the price of raw materials is much higher than the processing fee. We compare the cost of hanging stone and ultra-thin stone, from the total cost of the materials and the use of cost analysis, commonly used in the external walls of the brown and Fujian 664, for example:
Hanging British brown total cost = 20mm thick stone hanging fee = 200 200 = 400;
The total cost of the sticky British brown thin plate = 5mm thin plate paste cost = 230 yuan and 30 yuan = 260 yuan;
The total cost of hanging 664 = 20mm thick stone hanging = 70 200 = 270:
Paste 664 Total cost = 5mm thin plate paste Fee = 120 yuan 30 yuan = 150 yuan;
According to the above figures and the actual situation, no matter how hard paste than hanging significant cost savings, but with the thin plate production technology matures, the fierce market competition, the prices are still falling space.
6, the appearance of the effect. Speaking of appearance we must first explore the specifications. General specifications of the wall hanging is 600mm x 900mm, the maximum will not exceed 800mm x 1200mm. Can not stand because the walls and cost, ultra-thin can do this specification. The Dalian Hua Tong has been able to mass production of 600mm x 1800mm thickness 5mm thin plate, 600mm x 1800mm paste it into the wall, presumably this spectacular hanging comparable. Another effect is hanging due to the coefficient of expansion of steel and pendant, also more than lcm left seam. Therefore, a wall of black lines. Thin stone paste to the wall, leaving 5mm slit. Therefore, the effect of hyperopia. If the entire wall, presumably this effect many materials can not match. Therefore, the appearance is one of the advantages of ultra-thin stone.
