Kodak manufacturing, a listed company in China, has an advantage in traditional polishing machines and edging machines. A certain automatic inspection equipment for finished product quality (size, deformation, etc.) has been applied in taolian large plate / rock plate production line.
On December 28, 2020, at the opening ceremony of "Qixin · journey" Kodak manufacturing headquarters building, Kodak manufacturing officials announced "focus on manufacturing · change journey". This year, Keda Jieneng was also changed to "made by Keda", which shows that after 10 years of diversified detours, Keda has returned to its starting and growing place and accumulated strength in order to make a difference in the international ceramic machine market competition.
Xitibente, the ceramic rock plate press has certain characteristics, and the rock plate products on the mold surface have highlights. The first machine is put into production in Spain, but there is no model project in China. In addition, the promotion time in the Chinese market is short, and no large press has been applied in Chinese enterprises by the end of 2020, so we still need to work hard.

For swing glaze spraying equipment, all enterprises first use Italian airpower equipment. At present, the domestic xinjingtai mobile glaze spraying cabinet has been used in many workers. Its price has obvious advantages over imported equipment, and its service life needs to be tested. The Italian "octopus" mobile glaze spraying cabinet also participated in Tanzhou exhibition in July this year, hoping to enter the Chinese market.
For the glaze line platform, domestic Tailai and blue power enterprises have performed well, and there is basically no need to import equipment.
The 3D distribution equipment in front of the rock plate press is mainly domestic equipment, but research and development still needs to be strengthened, and the distribution equipment of LB company has not been used.
The finished product size and deformation detection equipment, domestic Keda equipment can be used well, and domestic large-scale defect classification equipment is also being tested.
Ceramic rock plate cold processing equipment is basically the world of domestic design. Many domestic enterprises, such as Yongda, Yongtao, aitao, Lange and other three-axis and five axis water knife processing equipment, have been widely used in various rock plate processing centers. The scale of the processing center varies from thousands of square meters to tens of thousands of square meters, from manual to mechanical automation, with an investment of millions to tens of millions of yuan.
Ceramic tile enterprises have invested a lot in technical transformation or new ceramic large plate / rock plate production line, with several million to tens of millions of yuan and 100 million to hundreds of millions of yuan. However, all ceramic enterprises closely follow up, spare no effort to adopt advanced production equipment, and strive to seize the commanding height of ceramic large plate / rock plate. The spirit of all enterprises is commendable!

The formula system is generally ternary potassium sodium aluminum silicon system or Quaternary potassium sodium calcium magnesium aluminum silicon system. The two formula systems have their own characteristics. At this stage, many enterprises have high requirements for the whiteness of green body, low requirements for the iron content of raw materials, relatively high prices of raw materials, and the formation of formula has also increased.
With the increase of machinability requirements, the alumina content in the formula of various enterprises is also gradually increasing, generally the alumina content is 20% - 24%.
Many ceramic slabs are gray black, so the application of black material increases, resulting in the increase of the application of vanadium titanium tailings in the formula of ceramic slabs.
In terms of glaze raw materials, dry particles are generally used for the bright surface, which began to rise in China, and the application of special flash materials in full polished ceramic rock plates has increased. In order to reduce costs, many enterprises adopt wet dry powder technology. All kinds of subsidence glaze, fine carving glaze, matte glaze, metal glaze and other ceramic rock plate surface applications have increased.

07 analysis and Prospect
● development speed
The speed of media publicity of Chinese ceramic large plate / rock plate is faster than the construction speed of production line, the construction speed of production line is faster than the construction speed of processing center, and the construction speed of processing center is faster than the application design construction speed. In the future, the development must be reversed, and the application design speed and construction installation speed must be increased.
● market limits
Ceramic rock plate has unlimited imagination and provides a realm, but the market is limited, not infinite. Therefore, new online enterprises must do a good job in market application positioning and scale positioning.
● economic scale
There must be a profit balance point for the reasonable scale of Xinshang ceramic rock plate production line, including single line, double line, three line and four line. All enterprises should make detailed accounting.
● cross border and Application
Ceramic rock board is applied in the fields of home, furniture, electrical appliances and so on. It has stepped out of the original ceramic tile field of architectural decoration. It has changed the track. There are new rules, and there must be new ideas and thinking.
● material and brand
Ceramic plate / rock plate is a new type of plate and a kind of material. Its application requires machining, so it is also a semi-finished product. However, semi-finished products can also have brands. Steel, cement, wood and glass are materials and semi-finished products, but they all have brands according to different characteristics. Only ceramic plate / rock materials with brands have vitality!
● product and design
In order to promote the large ceramic plate / rock plate well, there must be good product design. At the same time, industrial design must be introduced, a variety of materials must be combined and applied, and must have aesthetic value, so that the deep-processing products of ceramic rock plate can have added value.
● quality and standards
At present, the quality of large ceramic plate / rock plate in the market is different, good or bad. Due to the lack of unified standards and unified inspection, there are various complaints about terminal applications, which will damage the product image and damage the rights and interests of consumers. Therefore, the industry must issue the standard of ceramic rock plate as soon as possible and continuously improve the product quality.
● import and export
2020 will be a watershed. China's ceramic plate / rock plate products will change from import to domestic. Domestic ceramic plate / rock plate will account for more than 95% of the market, but a small amount of foreign products will also be imported.
● plate and processing
The difference between ceramic rock plate and ceramic large plate root is that the former can only be applied after 100% machining, while the latter can be directly used for building wall and floor decoration without machining. In 2020, we will focus on the construction of various plate production lines, and in 2021, we will focus on the construction of plate processing centers, including factory owned forms, joint construction forms and self built forms of terminal dealers. The purpose is to supply the processed plates to customers.
● ceramic rock slab and natural stone
From the perspective of policy development trend, the mining, processing and application of natural stone are in a downward trend, and the output and application of ceramic rock plate are in an upward trend. The comprehensive performance index of ceramic rock plate is better than that of natural stone, but natural stone also has its own unique performance and decorative effect. Therefore, ceramic rock plate cannot replace natural stone 100%, In particular, natural stone has certain advantages in three-dimensional and three-dimensional processing with a certain thickness.
● ceramic rock plate and artificial stone
Artificial composite stones such as quartz stone and artificial stone have unique performance and decorative effect. They have developed well in China in recent years and are exported to foreign markets. Products are widely used in kitchen countertops. Ceramic rock plates will also enter this field. The two types of products will also have fierce market competition.
● ceramic rock board and wood board and composite board
In the field of furniture, the panel is generally made of man-made composite board (three in one, four in one, five in one...) and natural wood processing. Aldehyde free is the development direction, while the 3.0mm glass fiber composite reinforced ceramic rock board is obviously superior to the composite board in terms of surface decoration effect and physical and chemical properties, and more importantly, aldehyde free, Therefore, the application prospect of thin ceramic rock plate in furniture is broad.
● inputs and outputs
The equipment investment of ceramic rock plate / large plate production line is larger than that of ordinary ceramic bricks, and the single line production capacity is lower than that of ceramic bricks. The ex factory price of large-size ceramic plate / rock plate is higher than that of ceramic bricks, and the input-output ratio is higher. The small and medium-sized ceramic rock plate, due to low investment, rapid enterprise transformation and large output, and the limited market, soon appeared that supply exceeded demand and the price fell. Many enterprises appeared to be lower than the price of ceramic tiles, and the input-output ratio fell.
● output and quality
On the whole, in 2020, the single line production capacity of China's new ceramic large plate / rock plate is still relatively small. All enterprises attach great importance to product quality, especially the cutting processability of products. All enterprises are equipped with special water knives for processability testing, but the methods and standards need to be unified. However, as individual factories pursue the production line with large capacity (15000, 20000, 30000 / day...) and put into production successfully, It may lead some enterprises to pursue large production capacity again, and the competition between quality and price will further intensify!
In 2020, the biggest harvest of China's ceramic plate / rock plate industry should be to correctly understand and distinguish what is "ceramic plate" and what is "ceramic rock plate". A series of forums will play a role in popularizing knowledge! In 2021, China's large ceramic plate / rock plate will face the biggest crisis is the pressure of capacity application and digestion after the short-term explosion of the production line. Many enterprises still hold on to the concept of ceramic brick production and management, and the price war is coming! The biggest opportunity for ceramic enterprises in 2021 is to change the track and explore new application fields!
Large ceramic plate / rock plate shoulders the important task of transformation and upgrading of the whole ceramic brick industry. The future is bright, but the road is tortuous. China's large ceramic plate / rock plate has a long way to go!
