There is such a phenomenon in the stone industry: the thickness of large slabs is getting thinner and thinner, from 20mm thick in the 1990s to 15mm now, or even as thin as 12mm.
Many people think that the thickness of the board has no effect on the quality of the stone.
Therefore, when selecting a sheet, the sheet thickness is not set as a filter condition.
According to the product type, stone slabs are divided into conventional slabs, thin slabs, ultra-thin slabs and thick slabs.
Stone thickness classification
Regular board: 20mm thick
Thin plate: 10mm -15mm thick
Ultra-thin plate: <8mm thick (for buildings with weight reduction requirements, or when saving materials)
Thick Plate: Plates thicker than 20mm (for stressed floors or exterior walls)
In particular, stone merchants with good materials and expensive prices are more willing to make the thickness of the slab thinner.
Because the stone is made too thick, the price of large slabs rises, and customers think the price is too high when choosing.
And making the thickness of the large board thinner can solve this contradiction, and both parties are willing.
Disadvantages of too thin stone thickness
①Easy to break
Many natural marbles are full of cracks. Plates with a thickness of 20mm are easily broken and damaged, not to mention the plates with a thickness far less than 20mm.
Therefore: the most obvious consequence of the insufficient thickness of the plate is that the plate is easily broken and damaged.
②Disease may occur
If the board is too thin, it may cause the color of cement and other adhesives to reverse osmosis and affect the appearance.
This phenomenon is most obvious for white stone, stone with jade texture and other light-colored stone.
Too thin plates are more prone to lesions than thick plates: easy to deform, warp, and hollow.
③ Influence on service life
Because of its particularity, stone can be polished and refurbished after a period of use to make it shine again.
During the grinding and refurbishment process, the stone will be worn to a certain extent, and the stone that is too thin may cause quality risks over time.
④Poor carrying capacity
The thickness of granite used in the renovation of the square is 100mm. Considering that there are many people in the square and heavy vehicles have to pass by, the use of such a thick stone has a large bearing capacity and will not be damaged under heavy pressure.
Therefore, the thicker the plate, the stronger the impact resistance; on the contrary, the thinner the plate, the weaker the impact resistance.
⑤Poor dimensional stability
Dimensional stability refers to the properties of a material that its external dimensions do not change under the action of mechanical force, heat or other external conditions.
Dimensional stability is a very important technological index to measure the quality of stone products.
