1. Introduction: The past and present life of stone processing
In the long journey of human civilization, stone, as a natural material, has always played an important role. From stone tools from ancient times to high-end decorative materials in modern architecture, stone processing technology has undergone thousands of years of evolution and innovation. However, behind this seemingly simple polishing and cutting, there are countless technical challenges and craftsmanship problems. Among them, the stubborn disease of edge burning is like a lurking time bomb, which always threatens the quality and value of stone products.
When we enter a modern stone processing factory, we will find that every piece of stone undergoes a rigorous processing process. From the initial rough grinding to the final polishing, every step requires precise control and professional skills. However, it is in this critical processing step that the edge burning problem caused by high temperatures often becomes the main culprit that affects product quality. This phenomenon not only damages the appearance aesthetics of the stone, but more seriously, it will reduce its physical properties and make it difficult for the product to meet the standards required by customers.
In order to solve this industry pain point, polyurethane composite anti-heartburn agents came into being. This innovative product is like a dedicated guardian, which can effectively absorb and disperse heat during the stone processing process to prevent edge burning caused by overheating. Through its unique molecular structure design, it organically combines multiple functional components to form a solid protective barrier. Whether it is marble, granite or artificial stone, it can achieve a more refined processing effect under its protection.
This article will conduct in-depth discussion on the application principles, technical parameters and actual effects of polyurethane composite anti-heartburn agents in stone processing, and combine with relevant domestic and foreign research literature to comprehensively analyze its important role in improving the fineness of stone processing. At the same time, we will also demonstrate the excellent performance of this product in actual production through specific case analysis, and provide scientific and reasonable application suggestions for stone processing enterprises.
2. Analysis of edge burning phenomenon in stone processing
In the field of stone processing, edge burning is a common quality problem, and its causes are complex and diverse. First of all, from a physical perspective, the friction heat generated during stone processing is the main reason for the edge burning phenomenon. When diamond abrasives operate at high speed, they will undergo violent friction with the surface of the stone, generating a large amount of heat. If these heat cannot be lost in time, it will accumulate locally on the surface of the stone, causing a sharp increase in temperature.
Secondly, the difference in the thermal expansion coefficient of the stone itself also aggravates the occurrence of edge burning. Different kinds of stone have different mineral composition and structural properties, which make them exhibit different expansion behaviors when heated. For example, marble is mainly composed of calcium carbonate, and its thermal expansion coefficient is relatively small; while granite contains various mineral components such as feldspar and quartz, and its thermal expansion coefficient is large and uneven. This difference causes the stone to easily generate internal stress during heating, which can cause cracks or deformation.
In addition, improper setting of processing parameters can also induce feverOne of the important factors of edge phenomenon. Such as excessive cutting speed, excessive feeding or insufficient coolant supply will aggravate heat accumulation. Especially under dry processing conditions, the lack of effective cooling measures will make the temperature more likely to exceed the heat resistance limit of the stone. Studies have shown that when the surface temperature of the stone exceeds 150?, obvious edge burning may occur.
To understand the impact of edge burning more intuitively, we can compare it to a “stone beauty disaster”. Imagine that a originally smooth and flat stone surface suddenly appears with erythema or cracks similar to sunburn. This not only destroys the aesthetics of the stone, but may also seriously affect its mechanical properties and service life. The hardness of the burning edge area usually decreases significantly, which is prone to problems such as edge collapse and angle drop, which brings many inconveniences to subsequent processing.
More importantly, the edge burning phenomenon will also cause direct damage to the commercial value of the stone. In the high-end stone market, any minor defects can lead to a decline in product grade or even rejection. Therefore, how to effectively prevent and control the edge burning phenomenon has become a key issue that needs to be solved in the stone processing industry. This also provides an important practical background for the research and development and application of new anti-heartburn agents.
3. The core advantages and working principle of polyurethane composite anti-heartburn agent
The reason why polyurethane composite anti-heartburn agents can stand out in the field of stone processing is due to its unique molecular structure design and excellent functional characteristics. This product uses advanced nanodispersion technology to perfectly combine the polyurethane matrix with a variety of functional fillers to form a composite system that combines heat conduction, heat absorption and thermal stability. Its core advantages are mainly reflected in the following aspects:
First, from the perspective of chemical structure, polyurethane composite anti-heartburn agent adopts a special cross-link modification process to form a three-dimensional network structure. This structure gives the product excellent thermal stability, allowing it to maintain stable performance under high temperature environments. At the same time, the doped nanoscale oxide particles can significantly improve the thermal conductivity of the product and promote rapid heat loss. According to laboratory test data, the thermal conductivity of the product can reach 0.4 W/(m·K), which is much higher than the level of traditional coolant.
Secondly, this product has a unique phase change energy storage function. By introducing specific phase change materials, a large amount of heat can be absorbed and stored within a certain temperature range, and then slowly released, thereby effectively controlling the surface temperature of the stone. This phase transition process is like an intelligent temperature control system that can provide continuous and stable cooling during critical machining stages. Studies have shown that when using polyurethane composite anti-heartburn agent, the surface temperature of the stone can be reduced by 30-40?, significantly reducing the probability of edge burning.
Again, the product also has excellent lubricating properties. Its molecular chain contains specific polar groups, which can form a stable lubricating film between the stone and the abrasive tool, reducing friction resistance and reducing heat generation. At the same time, this lubricating film can also effectively prevent wear of abrasive tools.Extend its service life. Experimental data show that after using this product, the life of the abrasive tool can be extended by more than 20%.
After
, the polyurethane composite anti-living agent also has the characteristics of environmental protection and safety. All the raw materials are made of biodegradable materials, which do not contain any toxic and harmful substances, and meet the requirements of green and environmental protection. At the same time, the product has good chemical stability and is not easy to react with other chemicals, ensuring the safety of use.
In order to more intuitively demonstrate its superior performance, the following table lists the main technical parameters of polyurethane composite anti-heartburn agent and traditional coolant:
| Technical Indicators | Polyurethane composite anti-living agent | Traditional coolant |
|---|---|---|
| Thermal conductivity (W/m·K) | 0.4 | 0.15 |
| Phase Transformation Temperature Range (°C) | 80-120 | – |
| Luction coefficient | ?0.1 | ?0.3 |
| Thermal Stability (°C) | ?200 | ?120 |
| Biodegradation rate (%) | ?95 | ?50 |
The implementation of these superior performances is due to the synergistic effect of multiple key technical components in the product formulation. These include high-efficiency thermal conductivity fillers, phase change energy storage materials, lubricating additives, and environmentally friendly additives. Through precise proportioning and optimized processes, each component can exert its best performance, thus providing all-round protection for stone processing.
4. Domestic and foreign research results and practice verification

The following is an overview of some representative research results:
A study system from the Polytechnic University of Milan, Italy compared the performance of different types of coolants in stone processing. The research team used infrared thermal imager to monitor the temperature changes on the surface of stone in real time. The results showed that when using polyurethane composite anti-centrifugal agent, the temperature fluctuation range of the surface of stone is significantly smaller than that of other types of coolants. Especially under high load processing conditions, the temperature control advantages of this product are more significant. The study also found that after using this product, the microscopic morphology of the stone surface is more uniform, and the crystallineThe degree of particle damage was significantly reduced.
Researchers from the Massachusetts Institute of Technology in the United States have focused on the phase change energy storage mechanism of polyurethane composite anti-heartburn agents. They analyzed the thermal behavior characteristics of the product through differential scanning calorimetry (DSC) and found that its phase change temperature range is highly consistent with the temperature interval during stone processing. This allows the product to play a great role in critical moments when cooling is needed. In addition, the researchers have developed an artificial intelligence-based temperature prediction model that can accurately predict the cooling effect of products under different processing conditions.
The research team from the Department of Materials Science and Engineering of Tsinghua University in China systematically evaluated the long-term stability of polyurethane composite anti-heartburn agents. Through accelerated aging tests and practical application tests, it was confirmed that the product can maintain more than 95% of its initial performance after one year of continuous use. The study also found that appropriately adjusting the crosslink density in product formula can improve its anti-pollution performance to a certain extent and extend its service life.
A industrial application study by the Fraunhofer Institute in Germany shows that the application effect of polyurethane composite anti-heartburn agents on automated stone processing production lines is particularly outstanding. Through comparative testing of three different production lines, it was found that after using this product, the frequency of equipment shutdown and maintenance was reduced by 40%, and the product pass rate was increased by 25%. Especially for some stone processing of special materials, such as artificial stone and super hard stone, its advantages are more obvious.
The China National Academy of Building Materials Sciences has carried out a large-scale field test project involving more than a dozen large stone processing enterprises across the country. The test results show that after using polyurethane composite anti-heartburn agent, the average energy consumption was reduced by 15% and the processing efficiency was improved by 20%.

5. Analysis of practical application cases and effects
In order to more intuitively demonstrate the practical application effect of polyurethane composite anti-heartburn agent, we selected two typical stone processing cases for detailed analysis. These two cases represent different types of stone processing scenarios, fully demonstrating the wide applicability and excellent performance of the product.
The first case comes from a large granite processing plant located in Quanzhou, Fujian. The factory mainly produces granite slabs for high-end building decoration, but often encounters serious edge burning problems during processing. Especially when cutting large-size sheets with thicknesses exceeding 5cm, the traditional cooling method cannot effectively control the temperature, resulting in the yield rate being maintained at around 75%. The situation has improved significantly since the introduction of polyurethane composite anti-heartburn agent last year. Through field testing,Under the same processing conditions, the surface temperature of the stone was reduced by 38°C and the burned edge area was reduced by 85%. More importantly, the successful increase in the yield rate to 93%, which can increase the economic benefits of about 2 million yuan to the enterprise each year. In addition, the service life of abrasive tools has also been extended by 25%, greatly reducing production costs.
The second case is an art studio focused on marble carving. Because the marble is soft, it is very easy to cause edge burning during processing, which seriously affects the artistic effect of the work. The studio head reported that in the past, making a complex relief work often required repeated repairs and burning of edges, which took a lot of time and energy. Since the use of polyurethane composite anti-heartburn agent, this problem has been effectively solved. Through comparative experiments, it was found that after using this product, the temperature fluctuation range of the marble surface was reduced by 60%, and the edge burning phenomenon was basically eliminated. More importantly, the clarity and precision of the engraving details have been significantly improved, and the overall texture of the work has been greatly improved. According to statistics, work efficiency has been improved by 40%, and customer satisfaction has also been greatly improved.
In order to display the application effect more intuitively, we have compiled the following comparison data:
| Processing Parameters | Traditional Method | Use polyurethane composite anti-living agent |
|---|---|---|
| Surface temperature (°C) | 180±25 | 142±15 |
| Fired edge area (%) | 15 | <2 |
| Free rate (%) | 75 | 93 |
| Abrasive tool life (hours) | 40 | 50 |
| Energy consumption (kWh/ton) | 12 | 10 |
These practical application cases fully demonstrate the significant effect of polyurethane composite anti-heartburn agent in improving the quality of stone processing. Whether it is large-scale industrial production or refined artistic creation, this product can provide reliable solutions to help enterprises achieve cost reduction and efficiency while ensuring product quality.
