1. The pattern is less realistic than natural marble, low texture
The pattern is dull, lacking the texture of marble, aura, rough look like so, but a closer look is difficult to have the natural marble charm and romantic style, fooling those who do not know stone can still. Natural marble after thousands of years is still active in the building decoration market and has not become the outcast of the times, has become the family home of the guests, into the mansion, certainly has its heavy roots, history, and cultural heritage, which is determined by the inherent characteristics and nature of the natural stone, and these inherent characteristics and intrinsic nature is precisely the rock plate is difficult to dig, emulate, is also difficult to surpass, or simply can not It is difficult or impossible to surpass them. This view is shared by some connoisseurs of slate.
Knowing this pain point, the slate industry promotes the features of slate with less of an effect that has surpassed or approximated the pattern or texture of natural marble. It is important to know that imitation is imitation, and there are still differences and, just as there are differences between genuine and forged paintings, there are always people with an eye to discern the differences and the authenticity.
2. The luminosity is lower than natural marble, lacking the light of natural marble
I once talked to a friend who was a rock slab and said that the luminosity of rock slabs was not as good as that of natural stone, and he said that rock slabs should have this matt luminosity and that the luminosity of natural marble was too bright. If the luminosity of rock slabs is low, it is difficult to achieve the crystal, translucent, glittering effect of natural marble, so when rock slabs are placed in front of natural stone they lose their light, like a star of light to a white dwarf, one shines brightly and emits a dazzling light; the other is like being in a black hole, shrouded in darkness. Whether the world prefers a star or a white dwarf is self-explanatory.
The stone has long been recognized for its beauty and brilliance in architectural decoration, and the slate should break through the current technical barriers and work hard to improve the luminosity, producing both low luminosity slate and natural stone PK luminous slate, why not? Just as the artificial stone is very low when it first comes out, through the super-clean and bright technology to improve the luminosity, to reach the natural stone luminosity, rock slabs should follow this practice to improve the luminosity of rock slabs. Otherwise, the slabs would be judged to be inferior to natural marble in terms of luminosity alone.
3. Cracking is the biggest pain point of rock slabs and the "cancer" in rock slabs
Although the metaphor of rock slab cracking as a "cancer" in rock slabs is inappropriate, rock slab cracking is indeed a very difficult technical and technological problem to solve, and rock slab processing cracking is also a worldwide problem. Ltd. Chairman Qiu Haibo revealed that the world's leading an Italian company cutting the proportion of cracks from 1% to 10%, 20%, "which is also their more headache". Because rock slabs are processed under high pressure and temperature, there is a huge amount of stress stored in the slab, which may lead to the release of stress once it is under the action of external forces, causing sudden cracking or bursting of the slab. This can be triggered by external forces during processing, external forces during use, or even the slightest external forces of weather changes, thermal expansion and contraction, which can lead to cracking. Sometimes the sudden cracking of a slab can be unexplained and we may not be able to find the cause.
The cracking problem of rock slabs is the biggest pain point of rock slabs and is also a fatal pain point of rock slabs. Cracking may be the main reason for the poor market outlook for rock slabs in the future.
4. Deformation of rock slabs, which affects production and construction accuracy
The deformation of rock slabs is also a pain point that cannot be avoided. The deformation of the slabs affects both the quality of the production process and the quality of the construction. It is no wonder that some installers have exclaimed that leveling is really difficult when installing rock slabs! In addition to the influence of the installation base, another factor is the large size of the slab. A little deformation in one part of the slab can have a big impact on faraway places, affecting the accuracy and quality of the installation. The large flexibility of the rock slab causes great inconvenience to the handling of the product, and the horizontal handling of larger lengths of rock slab products can easily cause the product to break because of the deformation that affects both the handling of the product and the product. Figure 3 shows the painful deformation of the rock slab, which is severe when 2 people are lifting the slab.
5. Rock slabs cannot be polished, and cannot be repaired after damage
One of the things that make natural marble fabricators turn their noses up at rock slabs is the fact that they cannot be polished or repaired by repairing them after they have been broken. If the slabs are deformed or deviated from the installation, or deviated from the closure, they cannot be removed by polishing like natural marble, which requires a high degree of responsibility and a high level of construction technology. This requires a high level of responsibility and skill in the construction of the slabs, but in practice, this is not possible for most builders.
The rock slab floor panels cannot be refurbished if they are installed out of alignment or if they are stamped out, and after 2 days of installation, they are grey. It's like a layer of grey on top of a beautiful snowflake white that can't be wiped off. This is what I was told by a friend who has experienced this problem and asked me to write about it in my article on the quality of rock slabs. When a slab becomes diseased or damaged in the course of its use, it cannot be restored by polishing, as is the case with natural marble.
7. The high hardness of rock slabs increases the difficulty of secondary processing
The hardness of rock slabs is high, reaching a Mohs hardness level of 7 or even higher, which exceeds that of granite and is close to that of gemstones. This high hardness makes the processing of the product extremely problematic. Otherwise, the surface of the rock slabs will be chipped, showing a jagged edge, a serious chipped bottom, or even a fractured edge, which will seriously affect the quality of the product and may even lead to the scrapping of the product; the high hardness of the rock slabs will result in a large and small head in and out of the knife, a thick middle and a thin end, which will seriously affect the quality of the back cut. The installation quality of the product.
8. Fragility of rock slabs
Cracking, bursting, fracturing, breaking with a slight external force, chipping, corner dropping, jagged edges in cutting and secondary processing, waterjet cutting from the opening, cracking during handling and transit all reflect the painful point of the brittleness of rock slabs. The brittleness of rock slabs is closely related to the manufacturing process of rock slabs and is not easy to solve unless there are major changes and innovations in the rock slab manufacturing process.
