China is a large ocean country with a coastline of 18,000 kilometers and a sea area of about 3 million square kilometers. It has abundant marine resources and a booming blue economy. According to the National Oceanic Administration's 2017 China Marine Economic Statistics. The Gazette shows that in 2017, the national total marine production value was 776.11 billion yuan, and the total value of marine production accounted for 9.4% of GDP.
Since joining the World Trade Organization, the proportion of China's foreign trade in national economic activities has steadily increased, reaching a level of 60%-70% of China's economy. It can even be said that without trade, the Chinese economy will be unsustainable. It is of great significance to explore the comprehensive competitiveness of the industry, explore new ways to protect and develop marine resources and the new mode of integrated marine management.
'Blue economy new engine' suffers from corrosion and the solution to the problem is imminent
With the continuous development of China's marine economy, especially the national strategic projects such as China's marine development and the Belt and Road Initiative, offshore oil and gas platforms, submarine pipelines, offshore wind power, ship transportation, sea-crossing bridges, marine transportation facilities are increasing, coastal harbor terminals Facilities such as coastal power plants are blooming everywhere. However, while vigorously promoting the construction of resource-saving and environment-friendly society in China, the rapid development of the marine economy still has the challenge of resource depletion and corrosion.
It is estimated that about 20% of the world's metal materials cannot be recycled due to corrosion. Therefore, the corrosion and protection of metals has attracted widespread attention from all over the world. Relevant information shows that the annual economic loss caused by corrosion is as high as 10,000 worldwide. The US$100 million is about six times the total economic loss caused by earthquakes, floods, hurricanes and other natural disasters. The annual economic loss caused by corrosion in China is 1.2 trillion yuan, about 441 bird nests, 7 Three Gorges Projects, 46 Qingzang Railways. The damage caused by corrosion has always plagued the world's industries, especially the marine corrosion.
Anti-corrosion market demand is rising, market economy will exceed one trillion
At present, the corrosion problem is mainly solved by coating the engineering equipment with anti-corrosion coatings. As a 'body armor' against corrosion, the market demand for anti-corrosion coatings is increasing. In China, especially for petrochemicals with strict requirements on anti-corrosion specifications. 4. Pipeline transportation, marine engineering and other industries, the demand for anti-corrosion materials and heavy-duty anti-corrosion coatings has maintained a steady and steady growth trend.
During the 13th Five-Year Plan period, the average annual growth rate of China's coatings industry's total output value is about 6.5%. By 2020, the total output value of China's coatings industry is expected to increase to about 560 billion yuan, and the total output is expected to increase to about 22 million tons.
Among them, heavy-duty anti-corrosion coatings, as coatings that can achieve a longer protection period than conventional anti-corrosion coatings in relatively harsh corrosive environments, are widely used in engineering equipment and facilities under severe corrosive conditions. The exploration and development of resources and the implementation of the strategic goal of 'going deep into the ocean', heavy anti-corrosion coatings will have a broader market volume.
After analyzing the data in recent years, we found that during 2010-2017, the sales revenue of China's heavy-duty anti-corrosion coatings market showed a volatility growth trend, and the growth was similar to the total industrial output value. In 2017, the heavy-duty anti-corrosion coatings industry achieved sales revenue of 88.465 billion yuan, Increased by 14.0%.
According to the forecast and analysis of Prospective Industry Research Institute's "2018-2023 China's heavy-duty anti-corrosion coating industry development prospects and leading enterprise business analysis report", by 2023, the heavy-duty anti-corrosion coating industry will achieve sales revenue of 19.1 billion yuan.
High-end anti-corrosion coatings are difficult to make domestic brands
China has a billion-dollar anti-corrosion coating market, but the domestic anti-corrosion market pattern is another scene. Take the ship heavy-duty anti-corrosion coating market as an example, Akzo Nobel, PPG, Haihong Senior, Jotun, Japan, Tuji, Japan Western companies and other foreign companies have basically divided 80% of the market share. In 2017, Haihong elderly, Japan's Zhongtu, Japan's Kansai and South Korea's KCC in the container heavy-duty coatings market share even reached an astonishing 95%, foreign giants Coatings companies have basically formed a competitive pattern of relatively monopolizing the domestic market. Even the heavy anti-corrosion coating market is growing at a high speed every year, which brings a certain opportunity for the growth of domestic enterprises. However, due to the gap in technology, domestic anti-corrosion brands are obviously lacking in market competitiveness.
As a developing country, China's economic and technological development has made great progress, but this does not mean that all technologies can compete with the international community. At least high-end heavy-duty anti-corrosion is not China. For historical reasons, China's anti-corrosion coatings The research and development started late, coupled with the long-term blockade of Chinese technology by the international community, China's anti-corrosion coating technology has a lot to go to.
It is understood that in the global heavy-duty anti-corrosion industry chain, from the raw material formula to the technology research and development and many other chain links, Chinese coatings companies can only rank the first echelon in the low-end. There is no independent intellectual property technology, lack of corresponding technical standards, The problem of iterative lag in production equipment is very unfavorable for the long-term development of China's blue industry.
Today, some large-scale, key projects in China, but where high-precision anti-corrosion treatment technology is required, can see foreign brands. For example, in the world's largest coal chemical Flour project built in China, the use of Akzo Nobel and Zos Dunda and other companies' heavy-duty anti-corrosion coatings. China's first tallest building - Shanghai Center Building's related anti-corrosion and fire-retardant coatings have basically adopted Akzo Nobel coatings. The above examples are endless. This has long been grasped by foreign paint giants. Key resources, like the throat that is caught at any time, once the problem occurs, it is immeasurable to corrode only one loss.
A well-deserved king of new materials, graphene, promotes a new change in the anti-corrosion industry
As a new type of nanomaterial, graphene has the reputation of 'king of new materials', its good barrier properties and shielding properties, as well as its excellent electrical conductivity, thermal conductivity, ultra-thin and ultra-large specific surface area, making it an anti-corrosion Coating properties, natural functional materials that reduce the cost of anti-corrosion coatings.
After many authoritative experimental data, graphene has played a particularly important role in anti-corrosion coatings as a key material. It can effectively block the external environment, corrosive substances and other metal substrates penetrate and diffuse, and form a dense protective layer with anti-corrosion. Good effect, low coating thickness, high adhesion, light weight, good mechanical properties, excellent salt spray resistance, long life and low cost. It is a good upgrade substitute for traditional anti-corrosion coatings. Once graphene is in anti-corrosion coating Successful application will greatly improve the negative impact of corrosion loss on economic development, and will also become a new bright spot and a new driving point for industrial anti-corrosion coatings.
According to the "2018 Graphene Technology Patent Analysis Report" released recently, among the total number of patents related to graphene technology in the world, China has the largest number of patent applications, reaching 37,521, ranking first in the world, accounting for 66.5% of the total. The support of policies, the drive of technology, and the entry of capital have brought new opportunities to China's technological innovation 'curve overtaking', and also ushered in new opportunities for change in China's industrial anti-corrosion coatings.
It is understood that domestic graphene anticorrosive coatings have become more mature, related technology research, landing application products with the expansion of market demand, paint companies to promote, graphene anticorrosive coatings are gradually recognized by related companies. It is worth mentioning Under the severe situation of the 'foreign enemy' pressure, graphene enterprises and paint manufacturers have a tacit understanding of the in-depth cooperation between R&D technology and production technology.
In the first half of this year, Zhuhai Polycarbon Composite Co., Ltd., which has rich experience in graphene research and development, and Jiangmen Jiabaoli Chemical Group Co., Ltd., one of the largest coating and coating solutions providers in China, launched a graphene epoxy anticorrosive bottom. Cooperation in the field of paint. I believe that in the future, in the high-end anti-corrosion coating market, China's anti-corrosion coating brand can not only catch up, but also compete with international brands on the international platform.
The advantages of graphene anticorrosive coatings are obvious. The economic and environmental protection effects are outstanding.
According to Mr. Chen Xiaogang, Chairman of Zhuhai Polycarbon Composites Co., Ltd., 'In addition to the traditional heavy-duty anti-corrosion coatings, graphene anti-corrosion coatings have significant improvements in performance, and they have the environmental and cost advantages unmatched by traditional anti-corrosion coatings. Corrosion is caused by the contact of metal surfaces with air, water or other corrosive media. The main method to solve the corrosion is to apply coating materials to the metal to achieve anti-corrosion purposes through physical isolation, chemical and electrochemical reactions. In the field, zinc-rich coatings are commonly used in the world to treat corrosion. Since zinc has a lower electrode potential than steel, the steel is not easily corroded by the action of the sacrificial anode, but the use of a large amount of zinc powder not only increases the coating cost, but also Come to the serious 'zinc pollution'.
The characteristics of graphene material make it have natural advantages in physical anti-corrosion and electrochemical anti-corrosion. The graphene sheet structure is layered and staggered, and a 'labyrinth' shielding structure can be formed in the coating, which can effectively inhibit the corrosive medium. Infiltration, penetration and diffusion improve the physical barrier properties of the coating. At the same time, the conjugated structure of graphene makes it have high electron mobility and exhibits good electrical conductivity. The layer structure also ensures that there is a coating between the coatings. Better electrochemical contact, forming a strong conductive network, which can achieve the same cathodic protection with less zinc powder.
In the formulation of graphene anticorrosive coatings, the principle of anticorrosion mainly refers to the powder which is mainly based on shielding. All of them can be replaced by graphene, and the addition amount of graphene is only 0.5%-2%. Replacing 30%-60% of anti-corrosion and anti-rust fillers, which can reduce costs and improve the environment, can be seen.
Time, location, people and gathering polycarbons into the graphene anti-corrosion 'fast lane'
According to CGIA Research, at the end of 2018, China's graphene anticorrosive coatings market will reach 500 million yuan. In 2020, the penetration rate of China's graphene anticorrosive coatings in industrial anticorrosive coatings will exceed 1%, which will reach 3 billion yuan, and will reach 48 in 2022. 100 million yuan, graphene anti-corrosion coating is expected to help domestic anti-corrosion coatings into the international high-end market.
Since the birth of graphene in 2004, in just a few decades, graphene has grown into a very large-scale industry with a trillions of volumes. In China, graphene has even risen to a national strategic level, supported by various policies and industry funds. The intensity is unprecedented, and governments at all levels have also introduced corresponding supporting policies and measures. Various graphene industry alliances, research institutes, innovation centers, and enterprises have sprung up.
As early as last year, Zhuhai Polycarbon Composite Materials Co., Ltd. has successfully realized the commercial operation of graphene anticorrosive coatings. Polycarbonate relies on its unique physical method graphene mass production patent technology, and has successfully developed through continuous accumulation of experience and practical application. Graphene oily and waterborne anticorrosive coatings. According to the inspection report issued by the Chemical Industry Synthetic Materials Aging Quality Supervision and Inspection Center, Zhuhai Polycarbon Composite Co., Ltd. produces graphene heavy-duty anticorrosive coatings in GB/T1771-2007 and GB/ Under the T 1766-2008 standard, the salt spray aging time can reach 3,600 hours, while the composite coating composed of graphene anticorrosive primer, intermediate paint and topcoat has a salt spray resistance time of more than 9000 hours. Breaking through the traditional epoxy The zinc-rich coating has a salt-tolerant limit of 800-1000 hours, and the domestic heavy-duty anti-corrosion coating products are going to be high-end.
Through previous reports, we found that Zhuhai Polycarbon Composite Co., Ltd. not only has a wide range of fields in the field of graphene anticorrosion, but also plays an important technical position in the fields of new carbon materials, mechanical lubrication, electric heating, and power energy. It is understood that polycarbon It has a number of patented technologies for the production of graphene mass production, and is also one of the few companies in the world that can achieve large-scale production at the cost generally accepted by the industry and truly realize the production and application of 'zero emission' graphene.
At present, the emergence of graphene anti-corrosion coatings, it is difficult to improve the long-term control of the Chinese anti-corrosion coating industry in a short period of time. The rise of the anti-corrosion coating industry is inseparable from the support of graphene technology, coatings manufacturers, policy-oriented and application-side. Generally speaking, graphene anticorrosive coatings have a bright future, but the roads are still tortuous. In the industry, more companies like polycarbons need to be promoted in all aspects of technology development, environmental performance assessment, standard setting, engineering application and industrialization. Development of graphene heavy anti-corrosion coatings.
During the actual visit, we found that the product end application of graphene anticorrosive coatings is not as prosperous as the online promotion, but Mr. Chen Xiaogang, the chairman of Zhuhai Polycarbon Composite Materials Co., Ltd., revealed to us that the polycarbon composite material has been successively related to 'China Three Barrel Oil, PetroChina, Sinopec, and CNOOC have made close contact with the leading companies in the petrochemical industry. Among them, in the contact with CNOOC, the coating test cooperation has been initially reached, and graphene anticorrosive coatings will be the first in which CNOOC Zhuhai natural gas power generation is limited. The company's large-scale steel structure is applied for coating. Chen Xiaogang said: 'This successful cooperation with CNOOC means that domestic anti-corrosion coatings have finally been recognized by state-owned enterprises, which proves that the performance of polycarbon graphene anticorrosive coatings is indeed superior to traditional anti-corrosion. Coatings, in the next anti-corrosion coating layout, we will be more confident to meet new challenges'.
The emergence of new heavy-duty anti-corrosion coatings for domestic graphene is like a timely rain, which not only improves the anti-corrosion quality of domestic anti-corrosion coating products, but also fills the market gap of domestic high-end anti-corrosion brands. This guarantees marine equipment, marine engineering and national major infrastructure. Safe service, promote the industrial upgrading of anti-corrosion coatings, impact the monopoly position of international brands in the domestic market, enhance the competitiveness of China's blue economy industry construction, and ensure the national security and marine economic development strategies are of great strategic significance.
