Problems solved by technology

However, there are many deficiencies in the method of processing equipment or accessories with metal materials: 1. The shock absorption capacity of metal materials is weak, so it cannot effectively absorb the vibration generated by the equipment during operation; 2. The coefficient of thermal expansion of metal materials is relatively large , the installation and debugging process of the equipment is very complicated, and the processing accuracy of related accessories is also greatly limited; 3. The corrosion resistance of metal materials is poor (especially chemical equipment), which requires frequent anti-corrosion treatment and high maintenance costs; 4. The processing technology is complicated, which makes the production cost higher; 5. There are problems such as large energy consumption and serious pollution in the processing process
Although the comprehensive strength of machine tools and equipment bases made of resin concrete in 200610044905.4 is better than that of artificial granite and marble mechanical parts in 200510043683.X, the coefficient of thermal expansion of the former is far greater than that of the latter, which fails to solve the complex installation and debugging of equipment , The problem of limited processing accuracy of accessories
Moreover, the addition of reinforcing materials not only increases the process steps, but also prolongs the production cycle
In addition, the existing epoxy resin concrete is easy to degrade and break the chain after being exposed to sunlight, so most of them have problems such as easy discoloration and powdering, etc.
