How do you avoid stone deformation? (1)

Stone deformation is a common phenomenon in stone products. After deformation, the installation quality of the stone is greatly affected, which not only affects the normal progress of construction but also seriously affects the decorative effect. The deformation of stone is inevitable for certain varieties, which is determined by the characteristics of the stone itself. Whether it is marble or granite, different degrees of deformation will occur when the thickness of the stone is too thin.

When the stone undergoes deformation, it is a headache that not only affects the normal installation, but also affects the normal processing of stone processing enterprises, and even leads to a large number of products being scrapped, causing significant economic losses. It is extremely important to solve the problem of stone deformation after stone deformation, and there are many technological means and methods. However, it is necessary to analyze the specific situation of deformation to solve the problem of deformation and make the deformed product meet the quality requirements.

In this article, we will give you some suggestions to solve the problem of deformation in stone products

1. Store indoors and avoid direct sunlight and rain

Stone products will deform under the exposure of sunlight; Some stone materials with high water absorption are also prone to deformation after absorbing moisture. Therefore, stone slabs and products that are prone to deformation due to sunlight and rain should be stored indoors as much as possible to avoid deformation caused by sun exposure or rain.

2. Vertical placement to reduce pressure

Large plates that may deform should be placed vertically at a 90 ° angle as much as possible; The large wooden frames packaged with wooden frames should be tightly wrapped, and tightly packed against each other, and the large boards should be packaged in a vertical and straight state.

3. Control dimensions and ensure appropriate vertical and horizontal alignment

For variable stone materials, when designing drawings, try to design the specifications and dimensions as small as possible to avoid deformation caused by excessive size and large differences in aspect ratios.

4. Control the sawing speed to ensure flatness

Some big boards and slats are deformed when opened out, and the flatness is poor, mostly caused by the speed of equipment when the block is sawing big boards. Therefore, if the flatness of the large boards and slats is poor during inspection, it is necessary to check whether the speed of the equipment is too fast. If the flatness of large plates and slats is poor due to the running speed of the equipment, select the appropriate and reasonable speed according to the characteristics of the stone. Reduce the running speed of the equipment and ensure the flatness of the big boards and slats.

5. Change the process to ensure flatness

The surface processing technology of some stone materials can affect the flatness of stone products. For example, on the surface of stone during fire, some stones may deform; The surface of the stone lychee surface will deform when struck by a machine. These stones can be replaced by other processes by changing the surface processing technology.

6. “Pressing” method to reduce deformation

After the deformation of stone, it can be reduced through the “compression method”. However, this method is only suitable for deformation caused by the stone itself and is ineffective for poor flatness or deformation caused by cutting. When both sides of the stone are upturned, use block stones to press both sides; When the stone arches and deforms, use block stones to press the middle arched part. The appropriate time for pressing is to restore the deformation of the stone to meet the standard of stone flatness.
