Ge Zhenhai, member and vice chairman of the Foshan Association for Science and Technology, delivered a speech first. He said that in recent years, ceramic slate has become a hot topic in the ceramic industry. It can not only be used as a wall and floor material for architectural decoration, but also has new and wider applications in the home furnishing industry, becoming a new material for pan-home applications. It is hoped that through this forum, all ceramic companies will seize the new ecology created by new technologies, use new technologies to empower themselves, improve the quality of products and services through technological innovation, and accelerate the promotion of the industry.The two-way integration of the chain innovation chain will unswervingly follow the innovative development path of "World Technology + Foshan Intelligent Manufacturing + Global Market", jointly promote the high-quality development of Foshan's manufacturing industry, and contribute to Foshan's striving to become the leader in high-quality development of prefecture-level cities in the province. Make greater contributions to the ceramic industry.
Chen Huan, President of the Guangdong Ceramics Association, spoke. He said that in this forum we will closely follow the main theme of industry development, specifically discuss hot topics and Internet celebrity slates, brainstorm and speak freely. In addition, the white papers "Foamed Ceramics Production Technology and Application" and "Ceramic Dry Powdering Technology and Equipment" were also launched today. In addition to better promoting technology, the white papers can also give recognition and recognition to the majority of scientific and technological workers who wrote them. , if we look at China, Guangdong, and Foshan from the perspective of world ceramics, we hope to spread the influence of Foshan, Guangdong, and China to the world through this white paper. Thank you to everyone who contributed silently to this event and the white paper. I hope this forum can benefit everyone and jointly promote the technological progress of the industry.
Feng Bin, Chairman of the Foshan Ceramic Society, said in his speech that in recent years, slate has been a hot issue in our ceramic industry. Our pioneers in the ceramic industry have made useful explorations around this new product, in the home furnishing industry, in the shipbuilding industry , breakthroughs have been made in other industries, and certain production has been formed. However, the equipment, materials, and technologies surrounding this production still need to be further improved. Therefore, the hot spot of today’s third forum on new materials, new equipment, and new technologies has become a technical forum for our ceramic slate slabs. focus, I believe that through a forum like today, especially the in-depth exchanges and dialogues we invited Professor Wu Jianqing, Professor Rao Pinggen, Zhang Boqing and more than 20 big names from all walks of life, we can push our slate technology to a new stage. , jointly pushing our slate technology to the world's leading level.
Wu Jianqing, a professor at South China University of Technology, brought a special report on "The Development Status and Trends of New Materials, New Technologies and New Equipment in the Ceramic Industry - New Ceramic Wall and Floor Tiles and Rock Slabs". Regarding the new ceramic tiles and rock slabs, he believes that the whole body is suitable for the surface formula of penetrating ink (part of which is added with a makeup soil layer), and the body formula is consistent with the surface color. The surface penetrating ink is used in conjunction with ordinary ink, and the effect is enhanced. The selection of color auxiliaries is more scientific. The development of body cloth technology can realize the reproduction of relatively complex body texture speed and details, which requires further research and development. The application of intelligent technology allows the surface texture to match the body texture. Regarding processing performance, he made several suggestions: 1. Use less freeRaw materials with a lot of quartz, or finely grind this part of the raw materials. Properly extend the high fire holding time. 2. When cooling, consider eliminating the stress caused by rapid cooling on the surface, and measure the glass transition temperature of the green body. 3. At the quartz transformation temperature of 573°C, the cooling rate should be appropriately reduced. 4. From 573°C on the surface to 573°C inside, it is an interval. Generally, control starts from the surface temperature of 600°C.
Forum dialogue session
The forum dialogues were divided into two groups. The first group of dialogues on new ceramic materials and their applications was chaired by Rao Pinggen, director of the Expert Committee of the Guangdong Ceramics Association and professor of South China University of Technology.
Liu Yijun, vice president of Mona Lisa Group Co., Ltd., said that if the processing methods and application methods of rock slabs are different, the front end, including the formula, firing cycle, amount of free time, and fineness of ball milling, will need to be adjusted. If Molding and equipment decoration inkjet machines, ink and other processing companies have joined in to form a supporting system to enter the field of slate, and then the entire industry chain will be opened up. With the advancement of supporting processing technology, slate products will surely form a very complete system from formulation to firing and application.
Dr. Ke Shanjun, manager of the Central Research Institute of Foshan Oceano Ceramics Co., Ltd., said that ceramic large slate boards are actually made by many companies, and many companies have such post-processing problems. In addition to the front-end ceramic factories and ceramic companies working on this technology and formula, I think the back-end cutting methods and cutting tools may be a breakthrough direction. Only relying on the front-end to do this may have bottlenecks. When the bottleneck comes out, we should gather all the sections and fields of our entire industry to break through this problem and improve it through technology. It cannot be solved through technology and materials. At this time, we can change our thinking and try our best from the back-end processing. to reduce the risk of cutting.
Huang Huining, deputy director of the Expert Committee of the Guangdong Ceramics Association and vice chairman of the Foshan Ceramics Society, said that the cutting problems of ceramic rock slabs are not only related to the composition of the green body, the combination of the green glaze, the expansion coefficient, the firing speed, and the quality of the brick after cooling. It is related to stress, and it is also related to our entire production system, operating model, input-output individuals and the business philosophy of the enterprise.. When making rock slabs, output should be controlled and quality should be the first priority. Secondly, when making rock slabs, we need to strengthen the control of formula, glaze matching, firing and the entire process, and put quality first.
Zhang Dailan, vice president of Guangdong Gold Medal Ceramics Co., Ltd., said that application channels determine production. Our Gold Medal pursues high-quality development rather than high-volume development. High-quality development is strictly controlled from the company's technology and the entire kiln production process. If we don’t pursue high-quality development, we will risk our lives. Everyone who makes ceramics will fight for price and quality, and in the end they won’t survive. Therefore, we must take the route of high-quality development and make big slabs and rock slabs. It develops healthily.
Zhong Baomin, vice president of Guangdong Dongpeng Holdings Co., Ltd., said that when producing slate, most of them still use the production method of ceramic tiles. When cutting and processing, they may still use the thinking of ceramic tiles. Enterprises should rationalize the relationship between slate and slate during production. The difference between ceramic tiles is that when processing them, many still use hard processing. So can we consider different methods? For example, after the rock slabs come out, some light wave detectors detect that the stress distribution of this batch of rock slabs may be different. Some processing methods can be used, such as hard cutting, and soft cutting, such as laser cutting. Is soft cutting possible? So I think the subsequent processing methods need to be explored to find a more effective way.
As for the decoration and functionality of rock slabs, Zheng Shulong, general manager of Foshan Mairis Technology Co., Ltd., said that with the rise of rock slabs and large slabs, the materials need to be more refined because of the decoration of the slabs and the texture of the surface of the slabs. The expression must be expressed in a digital way, including the application of rock slabs. The texture and touch of the surface are very important. Digital decoration is more refined. It is not like spray glaze. When spraying, more spray is sprayed in the middle or on the sides. Many, it will affect the texture, touch, light, and transparency of the surface. To express these feelings, only digital glaze can express it, including the currently emerging antibacterial materials. It will be better if it is expressed digitally. It means that it can be more evenly distributed on the surface, so the functionalization of materials and the digital technology of our company have played a big role in promoting it.
Qiu Haibo, chairman of Foshan Kehaiyino Ceramic Technology Co., Ltd., said that the requirements for ceramic tiles and rock slabs are still different. There are no clear standards now. We are making glazes through digital and some craftsmanship. I want to solve this problem. Another thing is wear resistance. Digital glaze has better wear resistance. This glaze system is different from the original one, so wear resistance is also very important. The second point is to pretendThe repair effect is because the slate is compared to the original board, such as stone, wood, and glaze, through digital and other methods, to achieve a real texture and upgrade it to the same texture as a natural board, so that the large board has a relatively strong vitality. and stronger application areas.
As for the anti-slip of ceramic tiles, Cai Zhuhong, deputy general manager of Guangdong Sanshui Dahong Glaze Co., Ltd., believes that anti-slip must not only be anti-slip, but also wear-resistant, anti-fouling, acid and alkali resistant, etc. The requirements of ceramic tiles must be met, so The anti-slip glaze part should be divided into two areas. One is wear-resistant ions. The wear-resistant ions can be dry particles or some high-concentration, high-hardness materials. The other is the basic glaze. Of course, wear-resistant ions must be To achieve anti-fouling and anti-skid, it is important to distribute the entire strength and match different strengths. Then strengthen the basic glaze, and adjust the basic glaze according to the firing temperature and firing time of different ceramic factories, as well as the wear resistance. When ions are used together, they can achieve both anti-slip and anti-fouling, acid and alkali resistance, which complement each other.
Quan Chunhui, general manager of Foshan Taoying New Materials Co., Ltd. (Zhongyang Glaze), said that as a supplier and service provider of glazes, we mainly do three things. The first one is the digital glaze of rock slabs. Glaze suppliers are accelerating the research and development and application in this area; the second is the basic glaze of rock slabs. Through the introduction of new materials and some optimization of formulas, some additional zirconium silicate in ceramic factories has been continuously reduced, thereby reducing zirconium radiation. , launching ultra-white top glaze and basic glaze; the third one focuses on the antibacterial effect given by slate in terms of function. Now through the introduction of antibacterial materials, the antibacterial rate of E. coli and Staphylococcus aureus can be achieved on slate. More than 99%.
Cheng Tao, general manager of Shandong Huicheng Ceramic Technology Co., Ltd., believes that slate mainly revolves around two things. One is its own physical properties; the second is surface decoration, because the application of slate is across industries such as home furnishing and decoration. industry, so the products it replaces have much higher requirements for surface decoration than previous ceramic tiles. For surface decoration, there are two points: First, the decoration of patterns. The influence of water-based ink will definitely be the development direction of the ceramic industry in the future. Because this is a method more suitable for current production processes. Second, there are some process problems in the production process, including glaze peeling, which will be eliminated. It is also an energy-saving product, so we need to continue to do some research and exploration around surface decoration.
The second group of dialogues on new ceramic equipment and new technologies was chaired by Zhang Boqing, director of the Mechanical Equipment Committee of the Ceramics Branch of the Chinese Ceramic Society and professor at Jingdezhen Ceramics University.
What new requirements does the issue of large slabs and rock slabs place on equipment? Jian Runtong, vice president of Guangdong New Mingzhu Ceramics Group Co., Ltd., said that he has not stopped in the field of rock slabs and large slabs. From 2016 to now, there have been 5 We are still in the process of setting up a large board with a size of 900 x 1.8 meters or more. We propose the production and manufacturing of 3-20 mm rock slabs. There should be many needs in this area from front to back, including raw materials, glazes, process technology, and equipment, from cloth, press to glaze line, to From kiln firing to subsequent coating processing, the processes vary from 3 mm to 2 cm. At present, our conventional production line, which is 1.6×3.2 meters, has exceeded the 3 mm process.
Chen Dong, executive deputy general manager of System (China) Technology Co., Ltd., said that from the perspective of slate, I think the year of equipment innovation has arrived, and all equipment can do it again. This is a problem of production capacity. , the future production line may have one press and two kilns, this is one. The second is more flexible. It is basically press forming, and the final board can be switched with one click, and the finished product can be switched freely. The third point is lower energy consumption. Now basically one square meter can consume 0.1 kilowatt of energy, which is more efficient, environmentally friendly and energy-saving.
Chen Zuixiang, press product manager of Keda Manufacturing Co., Ltd., said that in view of the problems of deformation and cracking of large thin plates, our company developed a new equipment the year before last, which is the square cover press, which is specially designed for large sheets. For thin plates, the forming pressure is more evenly distributed, the thickness error is smaller, and the stress is smaller. If it is like a traditional press, the stress will be relatively poor. The difference is 10 MPa or 20 MPa. For square If it is covered, the pressure will be very small, which is more suitable for thin plate molding. Bricks of 3.6 meters and 3.2 meters are basically no problem.
Jing Haishan, general manager of Foshan Delitai Technology Co., Ltd., said that the pain point of slate boards is energy consumption. Before making large slate boards, the energy consumption was very high. Now Delitai can dry 5 layers. The energy is reduced to 0, which means that through the heat exchange system of our kiln, 70%-80% of the heat of the kiln is recovered through supplementary heat, and then dried after recovery. When making rock slabs, the dryer is very critical. I recommend that you choose 7 layers of drying. It is difficult to make a kiln very wide. If you are making a 6 mm plate, I suggest you make it as wide as possible, so that energy consumption can be greatly reduced.
Foshan Ceramics Research Institute Co., Ltd.Qiao Fudong, executive director of the company's King Kong Research Institute, said King Kong's No. 1 in rock slab kilns is combination boxing. We use more than four types of rollers in the overall rock slab kiln, including high-rigidity rollers in the low-temperature zone and rollers in the high-temperature zone. Thin rod close-packing technology, because the temperature in the high temperature zone is generally very high and the load is high, the roller rods are generally thick, we use thin ones, the strength of the thin roller rods is relatively high, with high net pressure, our equal net pressure strength is higher , generally use 650 rods, the second is the close-packing technology of thin rods; the third is straightness and roundness, the roundness of the roller must be very round, a roller is 4.5 meters long, and the diameter cannot be different. The roundness is different, which will lead to slight deformation when making rock slabs and thin plates.
Tang Zhenhua, general manager of Guangzhou Jingtao Mechanical and Electrical Equipment Co., Ltd., believes that digital printing accounts for a small proportion of slates. The large slab and slate industry will definitely be concerned about the issue of non-duplicate environments in the future. We are currently also I am launching a new system, which is to produce 1.8 meters by 3.6 meters of rock slabs without duplication on 100 sides. I am still confident in the future promotion of this system.
Liang Haiguo, general manager of Guangdong Bohui Mechanical and Electrical Co., Ltd., said that digital integration and digital fabric integration are concepts we launched in 2015. Now the market is slowly maturing and many companies have gone online for production. Some people ask whether the cloth machine can completely replace the inkjet machine. Powder spraying cannot represent inkjet nano-level materials. I think the full-body slate will be a very important trend in the future.
Wang Huamin, senior director of Shenzhen O-Net Technology Co., Ltd., believes that ceramic tile testing is now divided into three major categories of demand. The first category of demand is manual replacement, which is the most basic demand. The second type of demand is to control the consistency of factory quality. The third type of demand is the control of the quality process. When we mentioned rock slabs earlier, we talked a lot about cracking. This actually belongs to the control of the quality process. For slate, O-Net hopes to bring some technologies, experiences, and ideas from other industries to the ceramic industry, so that we can work together to promote the penetration of this rising product in applications or the entire market as soon as possible.
Li Jinhua, general manager of Foshan Blue Whale Technology Co., Ltd., said that in recent years, the ceramic industry has been promoting the themes of green manufacturing, energy conservation and environmental protection, energy conservation and emission reduction. Our company is engaged in ceramic raw material processing and was established in 2018. The raw materials we make are still made from traditional ball mill balls. Through our dehydration method, the materials are dried with the flue gas of the kiln. This is such a raw material processing process. Our production line has been in use for about a year. We are in trial production and can produce raw materials.The powdering process does not require coal consumption.
After the exciting dialogue session, the strategic cooperation and four new production line project signing ceremony between Milano Group, Keda and Litai was held. Hu Zhenghua, Chairman of Milano (Group) Company, and Bian Cheng, Chairman of Keda Manufacturing Co., Ltd. After signing the contract on stage, the project is now under full construction and is expected to be fully operational by the end of the year.
The signing ceremony for the strategic cooperation between Ningxia Kehao, Keda and Litai and the slate intelligent whole-line engineering project was held. Yu Bin, general manager of Ningxia Kehao Ceramic Technology Co., Ltd., and Bian Cheng, chairman of Keda Manufacturing Co., Ltd., came to the stage to sign the contract , this project is a model project for Keda and Litai in the northwest, and it is also a benchmark project for the most important transformation and upgrading of Kehao Ceramics.
