What are the advantages and disadvantages of marble tiles?
Scarcity of resources is another essential problem of natural marble. Natural marble mine all mine a sometimes there are obvious differences, including color, texture, texture and so on, and can not guarantee the quality of supply when used in a large number of guarantee, there are many not the control factor. Natural marble as a high-grade stone, the price is expensive, per square meter in the thousand dollars or so, the import of expensive varieties and even up to ten thousand yuan. In particular, natural resources have decreased year by year, demand, prices. The marble tile stable supply, the price is only natural products of the 1/2 or 1/3, or even lower, the investment cost is greatly reduced, with the packaging, transportation, insurance and other related costs reduced, saving money is very considerable.
Low density of natural marble, there are imperceptible to the naked eye of the micro gap, easy to water seepage. In the process of cutting stone, paving and put into use, should pay attention to cleaning. Once the sewage is difficult to eliminate, lose luster, affecting the decorative effect. Therefore, the construction must be done before the relevant protection, the use of the need to carry out regular care, both trouble and increase costs, and marble tiles do not have these problems.
The advantages of natural marble in nature, shortcomings are natural. Low flexural strength of natural marble. Tile bending strength of more than 30MPa, so the thickness of the ceramic tile according to the specifications of only 10mm-14mm. But the natural marble flexural strength is low, generally easy to fracture at about 10MPa, especially the larger long sheet is more likely to fracture and breakage, so natural marble thickness generally in 20mm to 25mm, because of natural marble thick, will bring the increase in unit weight per square meter, which not only increases the cost of transportation, paving the difficulty it will occupy the building space, and the load of the building, increase the cost of buildings.
There are defects in natural marble, large color difference, there is a crack, is the natural property of uncontrollable. Stone industry has such a saying: "there is no crack marble is not marble", so in the production process, there is a necessary process: glue. After the resin material to fill the crack and then polish. Furthermore, cutting a boulder into a plurality of blocks of surface color texture changes greatly, color is another headache, so Dali stone in the factory must be in the factory layout, number, to ensure that the paving color difference is not too large, in the construction process, once damaged, it is very difficult to find a supplement to the same color and texture. Marble tiles, there is no such problem.
