How do you avoid stone deformation? (2)

7. “Bundling” method to reduce deformation

The “bundling” method is quite effective in reducing stone deformation, especially suitable for stone products with soft and easily deformed materials. The author once used this method to solve the installation problem of Italian green and jazz white cylindrical deformation at Nanning International Hotel. The “bundling” method is to use iron wire, ropes, and packaging plastic tape to forcefully bind deformed products to reduce deformation.

8. “Burning” method to reduce deformation

If the specification board is deformed and the front and middle are elevated and arched, the back can be burned with fire to reduce the deformation of the specification board.

9. “Hammer” method to reduce deformation

For some deformed boards, if they are arched from the front, the concave surface can be facing upwards and the deformation of the product can be reduced using the “hammer” method or tapping the lychee surface method; If the back is arched and the concave surface is facing downwards, use the “hammer” method or tapping the lychee surface method to reduce the deformation of the product.

10. “Reinforcement” method to reduce deformation

For those oversized and easily deformed specification boards, 2-3 pieces of rough stone strips can be added to the back of the stone, or aluminum or steel strips can be used as reinforcing bars to increase the strength of the stone and reduce deformation.

11. “Grinding” method to reduce deformation

For some deformed and poorly leveled boards, manual grinding or fully automatic continuous grinding can be used to remove the deformed parts and ensure the flatness meets the standard. Use hand grinding to focus on polishing the four edges of the front side of the high specification board, ensuring that the flatness error reaches the specified range while ensuring the thickness of the board; The specification plate arched in the middle is polished with a hand grinder to ensure the flatness meets the quality requirements.

12. “Stacking” method to reduce stone deformation

If the stone is deformed after cutting, place the board horizontally from the back to the back, stack multiple pieces together, and leave them for 1-2 days to reduce deformation, and even make the deformation naturally recover, achieving the required flatness.

13. “Flat laying” method to reduce stone deformation

Many large stone slabs and stone specification slabs are prone to deformation or exceeding the flatness standard when placed vertically or obliquely. However, once they are placed flat, the deformation is restored and the flatness meets the standard. Therefore, the flatness inspection of large boards and specification boards should be carried out in a horizontal position. Some stones cannot be placed in a suspended or flat position, as they are prone to deformation under the influence of gravity.

14. “Vertical placement” method to reduce stone deformation

The placement of stone specification boards should be vertical, just like large boards, and they are prone to deformation when placed at an angle. For stones that are prone to deformation, especially when there is a significant difference in aspect ratio, the stone specification board must be placed vertically to reduce the deformation of the stone.

15. “Support” method to reduce stone deformation

After the stone product is supported, it increases the support force and can reduce the deformation of the specification board.

16. Increase the thickness of the stone

To reduce the cost of large slabs and improve the yield of raw materials, stone slabs have been developed in an ultra-thin direction. The biggest problem with ultra-thin large boards and ultra-thin specification boards is their tendency to deform. The deformation solution in this situation can only increase the thickness of the stone or thicken the thin stone through other means; When processing irregular lines of easily deformable stone, it is easy to deform when the thickness of the lines is thin. An important method to reduce line deformation is to reduce the length and size, and increase the thickness of the line, or, if it does not affect the installation, the back can be treated by pasting marbles.
