Suddenly, Rockbeam is in the limelight Covered the big board. Last year it was still "no big boards, no big names", today it has become "no rock boards, no big names". So, what is the difference between large slabs and rock slabs?
What is certain is that rock slabs are an upgraded version of large slabs, which are iterated and evolved on the basis of large slabs. If the big board is version 1.0, then the rock board is version 2.0.
What is a big board? What is rock slab? Up to now, there is no unified and authoritative definition and concept in the industry. In fact, this does not hinder the development of the slab and slate industry, because the innovation of enterprises will always be ahead of the relevant national standards. For example, the antique tiles, full-glazed tiles, ceramic sheets, marble tiles that were once popular in the industry are the only way to have innovative products that can continuously meet the needs of the market.
The author interprets the connection between the two with a glimpse, hoping to help sort out the concepts of large slabs and rock slabs.
Let’s first look at the similarities between the two:
Both are ceramic plates made of inorganic non-metallic materials, which require a series of processes such as raw material preparation, pressing and molding, surface decoration, high-temperature firing, and mechanical cold processing; they are all plates, and Non-bricks, with certain specifications. There is no unified standard for how big it should be. According to the national standard "Ceramic Plate", the minimum size should be 900×1800.
Let’s take a look at the differences between the two:
From the perspective of specifications,the current mainstream specifications of large boards are 900×1800, 1200×2400, 1600×3600, and of course there are larger Specification products also include a batch of medium plates with specifications below 900×1800, mainly 750×1500. Some companies also call 600×1200 specifications medium plates; while rock slabs generally do not include Medium boards with specifications below 900×1800 are mainly 900×1800 and above.
From the thickness point of view, large plates include thin plates below 6mm and thick plates over 25mm. The thickness of each manufacturer varies; and rock slabs, obviously Excluding thin plates below 6mm and those super thick plates, the thickness is mostly 15-22mm. Of course, the larger the specifications, the thicker the thickness.
From a performance point of view,the surface hardness and flexural strength of the large board are very high, and both can reach "double zero" water absorption, which is far better than Compared with ordinary ceramic tiles, the body is not necessarily full-body; rock slabs are different. First, due to its later processing requirements, its strength, hardness, and density are far better than those of large slabs. It is also acid and alkali resistant and has zero Formaldehyde, secondly, the green body must be whole-body, and it must be "the same on the outside and the inside" to facilitate later processing and application.
From a production perspective, due to higher quality requirements, the tonnage of presses for rock plate production is larger than that of large plate production presses Larger, usually above 10,000 tons. Currently, mainstream enterprises in the industry use 36,000-ton or 45,000-ton slate production presses. The larger the tonnage, the higher the quality. However, those products produced by presses less than 10,000 tons, whether large slabs or slate slabs, have inherent quality. There is a certain difference, which is particularly obvious in later processing applications. Low pressure and uneven distribution lead to uneven stress inside the rock slab and are easily broken.
On the surface, although large slabs are mainly imitated natural stone, there are still many products imitating wood, imitating jade, imitating cloth, and even imitating natural stone. There are overlays of various patterns such as solid colors, wallpapers, and terrazzo, including industrial style, post-modern, etc.; while the rock slabs mainly imitate the texture of natural rocks to highlight the performance of their "rock" slabs; the large slabs have bright, soft There are various effects such as light and natural surfaces, while rock slabs are mostly bright and soft light; imitation stone slabs pursue four-continuous patterns, eight-continuous patterns, or even infinite continuous patterns as their selling point, but rock slabs usually do not pursue infinite continuous patterns. The texture is mainly based on the realistic and delicate texture, pattern and texture.
From the application point of view,The application of large slabs is mainly on the wall and floor planes of homes and commercial spaces. They mainly compete with traditional ceramic tiles for space applications, such as paving. Floors and walls, including background walls, etc., and of course outdoor walls, curtain walls, tunnels, rail transit, etc., as well as deep processing of porcelain art based on this, such as large-scale porcelain art paintings, background walls, hanging paintings, etc.; Slate is mainly used for geometric three-dimensional spaces in home applications, including dining tables, desks, bar counters, cabinets, wardrobes, bathroom cabinets, furniture countertops, partitions, linings, backboards, etc. It is mainly combined with traditional natural stone and artificial stone. , wood products and other materials compete for application scope and space.
From a processing point of view, the main processing methods during the application of large boards are cutting and splicing, such as walls and floors in large spaces. Compared with rock slab processing, it is much simpler. It can be upgraded by traditional tile pavers after professional training. Of course, it also needs to be paved with some professional paving tools, including wet tiling, tile adhesive sticking, keel dry hanging, etc.; Slate slabs are mostly deep-processed, including cutting, drilling, edge digging, chamfering, closing, splicing, pasting, etc. It is highly professional and technical and requires a series of professional equipment. If you are not careful, it will be damaged. Causes damage and waste to rock slabs. At present, most enterprises' deep processing of rock slabs is outsourced and implemented by professional supporting processing plants.
Judging from the name, rock slabs are obviously better than big slabs. Big slabs only reflect the "bigness" of product specifications, while "rock slabs" ” not only includes the “bigness” of product specifications, but also reflects the intrinsic performance and characteristics of the product. The difference between one word and one word clearly shows the realm and level. Because of this, "rock slabs" have become a new species in the industry, and many past large slab products have also been transformed into rock slab products.
Slate is a vent and a piece of fat. At present, various concepts and hype about rock slabs are rampant. Busyness is a good thing, it can promote the development of the slate industry faster, but you must also stay calm and clear-headed in the bustle, and don't let the wind blow you away.
