The security chip market in China is showing strong growth potential, with the electronics sector (excluding engineering and services) expanding from RMB 27.63 billion in 2005 to RMB 143 billion by 2012, reflecting an average annual growth rate of over 20%. This rapid expansion has been driven by the increasing demand for security solutions, particularly in video surveillance and intelligent monitoring systems. As a result, the industry continues to grow at a robust pace, signaling a bright future.
Security technology has evolved significantly, moving beyond basic video recording to incorporate advanced intelligent analysis. These technologies help detect and prevent crimes more effectively, contributing to public safety and social stability. At the heart of this development is video compression technology, which has matured over the years, enabling efficient storage and transmission of high-quality video data.
For many years, the chip industry in China faced significant challenges due to its reliance on foreign technology. However, after decades of effort, the domestic chip industry has made remarkable progress. According to data from "China Manufacturing Network," there are now over 1,188 registered chip companies, with four new ones being added daily. This surge indicates a growing interest in the chip sector, with many startups focusing on chip design and innovation.
During the "Eleventh Five-Year Plan" period, China's integrated circuit (IC) production grew from 26.11 billion units to 65.3 billion, with an average annual growth rate of 20.1%. Sales revenue increased from 70.21 billion yuan to 144.02 billion yuan, reflecting a 15.4% annual growth. The chip manufacturing industry also saw steady growth, rising from 23.29 billion yuan to 44.71 billion yuan, with a 14% annual increase. Experts like Ms. Wang Qinsheng from the China Semiconductor Industry Association note that regional clusters such as the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin area have become key players in the chip industry, each with unique strengths and capabilities.
Looking ahead, the Chinese government has identified the chip industry as a core strategic sector, aiming to foster innovation and technological independence. The "Twelfth Five-Year Plan" emphasizes the need for the industry to focus on core technologies, product quality, and international competitiveness. This direction is crucial for ensuring sustainable growth and long-term success in the global market.
Despite the positive outlook, the security chip industry still faces several challenges. One major issue is aligning chip development with the fast-paced evolution of security products. The current update cycle for security chips is about a year, which can lead to delays in product releases and increased costs for manufacturers. Additionally, the growing diversity of security needs requires more specialized chips, making it harder for one-size-fits-all solutions to meet all user demands.
Another challenge is managing the industry chain effectively. Due to the critical nature of security chips, their market behavior can significantly impact the broader security industry. Balancing market expansion with cost control is essential, especially as competition among chip manufacturers intensifies. Moreover, the pressure from declining profits in the security sector and the rising cost of intellectual property adds to the complexity.
To stay competitive, domestic manufacturers must focus on creating integrated solutions that combine hardware and software advancements. Developing independent standards tailored to the security industry is also vital. For example, the SVAC standard, or "Surveillance Video and Audio Coding," was developed to meet the specific needs of video surveillance. It supports scalable video coding, allowing for flexible delivery of video streams based on network conditions. This feature improves efficiency, reduces storage and transmission costs, and enhances interoperability between different systems.
In addition, the GB28181 standard, set by the Ministry of Public Security, aims to unify communication protocols across security devices, reducing compatibility issues and lowering infrastructure costs. When combined with the SVAC standard, these initiatives will play a key role in shaping the future of the security chip market, driving innovation, and promoting widespread adoption of advanced technologies.
Low Porosity Refractory Brick
Low porosity clay bricks are made of low aluminum mullite as the main raw material, formed by high pressure molding and high temperature sintering. The main mineral composition is mullite phase, the product has excellent high temperature physical properties and chemical erosion resistance.
Low porosity clay brick stability is good, the degree of erosion does not occur sudden change, than ordinary clay brick life increased by 2 to 3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks 50% to 60% higher than the thermal efficiency of the kiln can be improved.
Low porosity clay bricks are characterized by:
1. Low porosity, 13 to 15%;
2. Load softening temperature is high for about 1472 ℃;
3. High compressive strength at room temperature, generally about 100MPa;
4. Good volume stability at high temperature and good abrasion resistance;
5. good resistance to infiltration and erosion.
Low porosity clay brick as a good clay refractory brick products, so often used in chemical erosion, temperature fluctuations in the environment, such as steel, glass, chemical industry. The effect is quite obvious in the use of glass hot room and the use of iron water tank.
