At present, there is no standard for "Sintered Stone" in the world!

Not in Italy, not in Spain, not in Turkey, not in India, not in Indonesia...

Sintered stone have only just begun to be promoted in the Chinese market. The construction of ceramic slab production lines in various places is very rapid, with 3 lines, 5 lines, 10 lines, 20 lines, 40 lines, 80 lines, 100 lines..., There are many problems to be solved not only in production but also in application!

Industrial elements such as sintered stone design, research and development, production, deep processing, application, consumption, and service need to be improved. Sintered stone companies, industries, and cross-border applications need to be planned in advance to benefit the healthy and sustainable development of the sintered stone industry. Sintered stone standards have received attention and attention in China, and many organizations have cooperated with enterprises to carry out related work. I believe that through in-depth research and testing, a good standard can be established.

Do you know the evolution process from ceramic tiles to sintered stone?

Let’s start to understand from their definitions.

What is ceramic tile?

Ceramic tiles are plate-shaped or block-shaped ceramic products produced from clay and other inorganic non-metallic materials through molding and sintering processes. They are used to decorate and protect the walls and floors of buildings and structures. It is usually molded by dry pressing, extrusion or other molding methods at room temperature, then dried and fired at a certain temperature.

Ceramic bricks with a water absorption rate greater than 10% are called ceramic bricks. They are generally called internal wall bricks in the market. They are widely used for wall decoration of residential buildings, hotels, public places and other buildings. They are the main products of interior decoration. Porcelain tiles with a water absorption rate of less than 0.5%, which are commonly referred to as vitrified tiles, are mostly surface-polished, so they are also called polished tiles. It is widely used for floor decoration of various buildings and is also the main product of interior decoration. Ceramic tiles with water absorption between 0.5% and 10% are partly used for exterior wall decoration, partly used for interior floor decoration, and are mostly used in bathrooms and used in conjunction with interior wall tiles.

According to the molding method, ceramic tiles are divided into extrusion molding ceramic tiles and dry pressing molding ceramic tiles. Among them, dry pressed ceramic tiles are divided into porcelain tiles (E0.5%), stoneware tiles (0.5%<E3%), fine stoneware tiles (3%E6%), stoneware tiles according to water absorption. (6%E10%) and ceramic tiles (E>10%).

What is the ceramic sheet?

Ceramic sheet (referred to as thin porcelain plate) is a plate-shaped ceramic product made of kaolin clay and other inorganic non-metallic materials through forming and calcination at a high temperature of 1200 degrees.

1. Product standard: GB/T 23266-2009 "Ceramic Plate";

2. Technical Regulations: JGJ/T172-2009 "Technical Regulations for the Application of Building Ceramic Sheets"

3. Specification: >= 900*1800mm (>=1.62 sqm)

4. Thickness<=6.0mm

5. Water absorption E<=0.5%

What is Large format ceramic board?

Large format ceramic board (referred to as ceramic board), described in English as Ceramic Board, is a kind of inorganic non-metallic materials such as pottery clay, ore, etc., and the area is not less than 1.62 square meters, which is made by molding and high temperature calcination at 1200. Plate-shaped ceramic products. Compared with other ceramic tile products, ceramic board have the characteristics of large specifications, high hardness, stable performance, safety and firmness, environmental protection and health, and strong decoration. Ceramic slabs are mainly used for wall and floor decoration of building spaces, furniture decorations such as wardrobe panels, cabinet panels, and door panels.

1.       Area:> 1.62 sqm

2.       Thickness>6.0mm

3.       Water absorption E<=0.5%

What is Sintered stone?

Sintered stone is a brand-new decorative material. The main ingredients are natural stone powder, silica and feldspar powder, etc., which are fired through a special process and a high temperature of over 1200 degrees Celsius. The Sintered stone has natural and delicate marble pattern, and it can also achieve super large size and super thin thickness. In addition, the Sintered stone has a Mohs hardness of over 6 degrees, has strong corrosion resistance, scratch resistance, and antifouling properties. It also has the advantages of cleanliness, fire resistance, high temperature resistance, environmental protection and no pollution.

Sintered stone are referred to as "rock slabs".

The material attribute of "Slate" is "ceramic"-inorganic non-metallic material.

Sintered stone -there is no size distinction,there is no difference in thickness. "Ceramic board" are distinguished by application field and machinability, mainly used in furniture countertops, cabinet panels, electrical panels. Comprehensive performance is better than "ceramic board". It can also be used on the interior and exterior walls and floors of buildings.

We gave the English name to “Sintered stone”

"Sintered stone" is abbreviated as "rock slab". This is a very nice name. It comes from the ceramics industry in China. It has a high level, rich imagination and large association space. It is literally understood "Use ceramic raw materials and technology to make natural stone like natural stone." A slab product with the same appearance and better performance than natural stone", there is no specific name in English, this is the innovation and creation of the Chinese!

What are the English names for "sintered stone " and "ceramic board"? We have collected relevant information, as follows:

1) sintered stone, "sintered stone" This is a professional name, with a special explanation of the meaning, from the product catalog of Italian/Spanish companies

2) big slabs, (product catalog of Italian companies)

3) Porcelain tiles, (printed on the packaging boxes of ceramic plates in an Indian company)

4) Techno slab, India Lioli ceramic board product packaging box printing

5) ceramic board, (China)

6) ceramic slab, (Italy/China)

7) ceramic plate, (China)

8) large ceramic slab, (China)

9) porcelain slab, (China)

10) rock slab, (China)

"Sintered stone/rock slab" is a good name. We must make a scientific definition. What is the difference between a large slab and a rock slab? We must carefully study and test it. What English name to use is worthy of our ceramic counterparts to think carefully.

Multi-dimensional analysis of "Sintered stone"

Technical performance requirements for sintered stone

1) Structural properties

2) Massive mechanical properties

3) Thermal hydrometric properties

4) Chemical properties

5) Safety properties

6) Electical properties

Sintered stone standard released

On Dec. 21th, 2021, the "Ceramic Slabs" (T/CBCSA 40-2021) Association Standards Release, Publicity and Implementation and Quality Evaluation Kick-off Meeting organized by the China Building and Sanitary Ceramics Association was held in the form of a video conference.

The standard has two major characteristics: First, it proposes the concept of product classification to promote industrial upgrading, increase the added value of products, and meet the needs of different consumers. Second, in terms of stipulating product performance, in addition to the requirement that the use performance meets the standard, it also requires the product processing performance, environmental protection performance to meet the standard, and meet the domestic production level. The "workability" test item is added because the slab has higher cutting and processing quality requirements than ordinary ceramic tiles. Environmental protection performance testing puts forward requirements for the precipitation and radioactivity of heavy metals on the surface. At the same time, the standard also requires that the products meet the domestic production level, so as to avoid the situation where the standard is facing high and low quality or crude products.

Sintered stone standard future

1) Fully detect and collect more abundant data

2) Through production, continue to summarize technical parameters

3) Obtain actual application data through actual use

4) Exchange of multiple group logos to make progress together and promote the development of the industry

5) Apply for the national standard of "rock slabs" and strive for production items

6) Promote Sino-foreign exchanges and jointly promote the introduction of international standards for ceramic slabs

7) Continuously deepen standard research and improve testing methods and instruments

8) Leading enterprise demonstration role, continuously improving the quality level of ceramic slabs

Sintered stone bring opportunities for the transformation and upgrading of ceramic tile companies. After more than ten years of basic work, sintered stone will usher in a development period. The standard and quality of ceramic slabs are the foundation of enterprise development. The whole industry has paid attention to "Sintered stone". Standards, the whole society cares about ceramic slate products and applications!

From ceramic tiles to ceramic thin plates, ceramic board and sintered stone, it is the progress of science and technology, the progress of the society, and the progress of the industry!

Look forward to our joint efforts to prepare a high-quality "sintered stone" standard!
