What is the disadvantage of Sintered Stone

Oct 16, 2020


Sintered stone or Porcelain slab has once become a hot word in the building materials industry in 2020. While affirming the superior performance of porcelain slabs, we must also face its pain points. The porcelain slabs have been covered up too deeply by everyone. This is not conducive to the future of porcelain slabs. While seeing the advantages of sintered stone, we must also admit its shortcomings, even fatal shortcomings. This is a dialectical and scientific point of view.


So what are the pain points of Sintered stone?


Pain point 1: Pattern fidelity is worse than natural marble, low texture


     The pattern is dull, lacking the texture and aura of marble. It looks like this at first glance, but it is hard to have the charm and romance of natural marble when you look closely. It is fine for those who do not understand stone. After thousands of years, natural marble is still active in the architectural decoration market. It has not become an outcast of the times, but has also become a guest of family residence. It has entered into a mansion, of course, it has its solid foundation, history and culture. This is determined by the inherent characteristics and essence of natural stone, and these inherent characteristics and inner essence are precisely what procelain slabs are difficult to excavate, imitate, but also difficult to surpass, or beyond. This view also agrees with this view in the eyes of some experts in porcelain slabs.


Pain point 2: The luminosity is lower than that of natural marble and lacks the brilliance of natural marble


     I once talked to a friend who made porcelain slabs that the luminosity of porcelain slabs is not as good as that of natural stone. My friend said that porcelain slabs need this kind of matte gloss. The luminosity of natural marble is too bright. When the luminosity of the porcelain slab is low, it is difficult to achieve the crystal clear, translucent, and shining effect of natural marble. Therefore, when the porcelain slab is placed in front of the natural stone, it loses its light; sintered stone manufacturer should break through the current technical barriers and work hard to improve luminosity. 


Pain point 3: Cracking is the biggest pain point of the sintered stone, and it is also called the "cancer" of the sintered stone


     The cracking of rock slabs is indeed a very difficult technical and technological problem to solve. The cracking of slab processing is also a worldwide problem. Because the porcelain slab is processed under high pressure and high temperature, huge stress is stored in the slab. Once under the action of external force, the stress may be released, causing sudden cracking or bursting of itself. This triggering factor may be the external force during processing, or the external force during installation, even the slight external force caused by the change of weather, thermal expansion and contraction, may cause the porcelain slab to crack. Sometimes the sudden cracking of the porcelain slab may be inexplicable and we can't find the reason.



Pain point 4: The porcelain slab is deformed, which affects the production, processing and construction accuracy


      The deformation of the porcelain slab is also a pain point that cannot be avoided or avoided. The deformation affects the quality of production as well as the quality of construction. 


Pain point 5: The porcelain slab cannot be polished and cannot be repaired after damage


     What makes natural marble processors most contemptuous of the porcelain slab is that its surface cannot be polished, and it cannot be repaired after it is with small damage. Once the porcelain slab is deformed, installed deviation, or closed deviation, it cannot be eliminated by grinding and polishing like natural marble. This requires the porcelain slab construction personnel to have a high sense of responsibility and high-level construction technology can guarantee it. But in fact, it is impossible for most construction personnel, not to mention that the construction of porcelain slabs is a new technology, and there are not too many or even very few high-level personnels.


Pain point 6: The high hardness of the porcelain slab increases the difficulty of secondary processing


     The hardness of the porcelain slab is high, reaching the Mohs hardness level 7 or even higher, which has exceeded the hardness of granite and is close to the hardness of gems. Such high hardness brings great trouble to the processing of this product. When cutting the board, you must use a special cutting saw blade, and the sharpness of the saw blade is always maintained during the cutting process, otherwise the surface of the slab product will collapse, showing jagged edges, serious bottom collapse, and even possible The edges and corners are broken, which seriously affects the quality of the product, and may even cause the product to be scrapped; due to the high hardness of the slab, there are two large and small heads in and out of the knife, and the middle is thick and the ends are thin, which seriously affects the installation quality of the back-cutting product.


Pain point 7: The porcelain slab is fragile


     Cracking, bursting, breaking of porcelain slab, breaking when a little external force is applied, chipping, corner drop, serrated edge appearing in cutting board and secondary processing, waterjet cutting special-shaped opening from opening, handling and transportation The cracking in the process reflects the pain point of the fragility of the slab. The brittleness of slabs is closely related to the manufacturing process of big slabs, and it is not easy to solve it unless the porcelain slab manufacturing process is greatly changed and innovated.




Pain point 8: The processing range of the porcelain slab is limited, and the application range is limited


     The processing range of sintered stone is much less than that of natural marble, which limits the use and application of sintered stone to a certain extent. For example, it is impossible or difficult to achieve products with multiple grooves on the surface of slab materials to manufacture parquet, mosaic products, and facade products. The small range of porcelain slab processing products determines that it is impossible to enter certain application areas of natural marble. Some areas can only be exclusive to natural marble, and it is impossible to replace natural marble. This can not but be said to be a regret and pain point of the sintered stone.


Pain point 9: fish and dragon mixed with beads, less real porcelain slabs, more fake sintered stone slabs


      This is purely an act of dishonesty by some businesses, and doing so will do the most damage to the sintered stone, The slab is in the stage of starting to run. Some unscrupulous manufacturers only made some improvements to the original ceramic production process, and appropriately added some process formulas of the porcelain slab. In the case of insufficient pressure, firing temperature and time So-called sintered stone slabs have been produced under the production. Can you imagine the quality? Consumers of inferior rock slabs are scrapped due to poor quality during production, processing and use. They cannot find the source of production and cannot get compensation. Will it not have an adverse impact on the future development of regular porcelain slab manufacturers? The ceramic industry does not immediately crack down on this kind of false cheating and formulates rock slab standards, which has a great negative effect on the future development of porcelain slabs.
