Save energy and be green.
The transportation industry is the pillar industry of the national economy and plays a decisive role in China's economic development. Due to the particularity of its equipment and facilities, the maintenance of equipment is essential for extending the service life of the equipment, maintaining the production efficiency and safe operation of the equipment. The therapeutic maintenance of the equipment is an important means of equipment maintenance, and the cleaning of the equipment is An important part of design maintenance. There are many places where the transportation industry applies cleaning. Such as: car cleaning, road bridge cleaning, and ship cleaning. Ship cleaning includes: cleaning of the oil tank, cleaning of the exterior of the ship, cleaning of the main frame, cleaning of the engine and cleaning of other parts.
First, with the development of productivity, social division of labor and specialized production processes, the need to further accelerate, the process of professional cooperation in the future, and the acceleration of the production process from the extensive production and operation to the intensive production and operation of shipyards, in order to improve the working conditions of employees. It is imperative to adopt an efficient cleaning operation. According to foreign statistics on ship repair and development, the number of ships in developed countries in the world accounts for 20% of the total number of ships per year (while China is lower than this value), plus the classification society's restrictions on ship age. There is still a great potential for strengthening ship maintenance. The cleaning of ships is bound to develop with the rapid development of the shipbuilding industry. The future is boundless.
Secondly, due to the irreplaceable superiority of chemical cleaning or mechanical cleaning, it is of great practical significance to consciously extend it to shipbuilding.
1. Energy-saving energy
Since the development speed of China's energy is still unable to meet the increasing demands for the time being, the central government's policy on energy is “developing and saving, focusing on saving”. Therefore, the use of chemical cleaning technology, mechanical cleaning instead of gasoline, diesel to clean, is an effective way to save energy.
2, safe and reliable
Because the chemical cleaning liquid is a non-combustible substance, it fundamentally solves the hidden danger of fire caused by gasoline and diesel cleaning, and most of the cleaning agent has no volatility, and the physical and mental health of the employees is ensured.
3, good cleaning quality, high efficiency
Today, shipbuilding must follow the principle of “short ship schedule, good quality, fair price and excellent service”. From the point of view of cleaning, if it is manually scraped, it is dirty and tired, low in efficiency, poor in quality, and in many places, the work cannot be approached at all. Such as: double bottom, main base and other parts, such as chemical cleaning and mechanical cleaning can easily solve these problems (mechanical cleaning can reach about 85% of all cleaning) greatly improve production efficiency, simplify production methods, ensure quality , shortened the build cycle.
4, does not damage components and parts
After cleaning the Precision components, there is also anti-rust and passivation protection. Such as: the ship's cooling water system, air cooler cleaning.
5, reduce costs
Taking Hainan Province in 1996 as an example, there are more than 4,000 ships, 300,000 deadweight tons, 11 shipyards, 20% maintenance rate per year, and about 800 ships need maintenance. According to relevant statistics, the 800-like ships use chemical cleaning machinery. Not only can it improve work efficiency, but it can also reduce costs by 50% compared with the traditional method).
Of course, with the improvement of the environmental awareness of our people. How to deal with cleaning waste liquid will be a concern of people, and it is also an important part of the promotion. Because the waste liquid contains not only oil and water (greater than 100PPm), but also the COD value of chemical oxygen demand is also high (more than 1000PPin). If the rivers and lakes are directly discharged, the water quality will be seriously polluted (national standard discharge standard, oil <l0PPm.COD<l00PPm). To this end, the cleaning department should adopt different treatment methods, such as biochemical method, ion exchange method, gravity separation method, etc. according to the type of cleaning agent, pollution situation, especially the discharge amount and water quality. Good results - to meet emission standards, people can rest assured.
In short, with the development of shipping industry, the requirements for repairing shipbuilding technology must be greatly improved. If the cleaning is still the old method, it is still in the original condition of diesel, gasoline and artificial scraping, which is not commensurate with cleaning and energy saving. It is also difficult to adapt to the requirements of the shipping repair industry to shorten the cycle, save energy and save efficiency. In order to change the cleaning appearance, high efficiency, high quality, safe and economical cleaning methods, it is not only an urgent requirement of the majority of industrial workers. It is also an inevitable trend of production development and technological progress.
Provide better batteries for urban trams, high-speed rails and other fields.
The success of the experimental phase of the new graphene battery will undoubtedly become a new development point of the battery industry. Battery technology is the biggest threshold for the promotion and development of electric vehicles. The battery industry is in the stage of bottlenecks in the development of lead-acid batteries and traditional lithium batteries. After the successful development of graphene energy storage equipment, if it can be mass-produced, it will be The battery industry and even the electric vehicle industry have brought about new changes.
Because of its unique characteristics, graphene is called "magic material", and scientists even predict that it will "completely change the 21st century." Professor Colin Bailey, vice president of the University of Manchester, said: "Graphite has the potential to revolutionize a wide range of applications, from smartphones and ultra-high-speed broadband to drug delivery and computer chips."
Recently, researchers at the University of California, Los Angeles, developed a graphene-based micro-supercapacitor that is not only small in size, but also 1000 times faster than ordinary batteries, and can charge mobile phones and even cars in seconds. It can also be used to make smaller devices.
The breakthrough of micro graphene supercapacitor technology can be said to bring revolutionary development to the battery. The main method of manufacturing microcapacitors is lithography, which requires a lot of manpower and cost, and hinders the commercial application of the products. And only need a common DVD burner, even at home, using cheap materials for 30 minutes to make more than 100 micro graphene super capacitors on a single disc.
It is the application prospect of graphene. Many countries have established graphene-related technology research and development centers, trying to use graphene commercialization, and then obtaining potential application patents in industrial, technical and electronic related fields. The European Commission has set up a special R&D plan as a “new future flagship technology project” and will allocate 1 billion euros in the next 10 years. The UK government has also invested in the National Graphene Research Institute (NGI) in an effort to bring this material from the laboratory to the production line and market in the coming decades.
China also has unique advantages in graphene research. From the production point of view, graphite, which is a raw material for graphene production, is rich in energy storage and low in price. In addition, mass production and large-scale production are the most important factors hindering the large-scale commercial use of graphene. The first 15-inch single-layer graphene was successfully fabricated by chemical vapor deposition, and the graphene transparent electrode was successfully applied to a resistive touch screen to prepare a 7-inch graphene touch screen.
Researchers at the Chongqing Institute of Green and Intelligent Technology of the Chinese Academy of Sciences are demonstrating the superior light transmission and flexibility of single-layer graphene products.
Because graphene has an unimaginable conductivity, the graphene battery concept has become a life-saving straw that breaks through the bottleneck of battery technology. Especially in the domestic electric vehicle industry, all technical breakthroughs are linked to graphene batteries.
With the deepening of research, the technical problems have been successively overcome, and the scope of application has been continuously expanded. It is believed that the era of graphene devices is not far away, and we can also expect some surprises from this "21st century magic material".
“The graphene battery will be reformed: charging 1000 km for 10 minutes.” Report: Spain's Grapheno Company (a company that produces graphene on an industrial scale) has collaborated with the University of Corvado in Spain to develop the first graphene polymer battery. The electricity storage capacity is three times that of the best products in the market. The electric vehicles that use this battery can drive up to 1000 kilometers, and the charging time is less than 8 minutes. Although this battery has various excellent properties, its cost is not high. According to the person in charge of Graphenano, the cost of this battery will be 77% lower than that of lithium batteries, which is completely within the consumer's tolerance. In addition, in the field of automotive fuel cells, graphene is expected to bring revolutionary progress.
Give your society a heart
Respecting the old, loving the old, helping the old is the traditional virtue of the Chinese nation, and it is the precious spiritual wealth passed down by the ancestors. In our long-standing and profound traditional culture, attaching importance to human morality and family harmony is the essence of our cultural traditions, and it is also a concrete manifestation of the strong cohesion and affinity of the Chinese nation.
China has begun to enter the stage of population aging. It is an important symbol of the progress of social civilization to effectively protect the legitimate rights and interests of the elderly and let them live a happy, happy, peaceful and healthy old age and share the fruits of human social development. Respect for the elderly is to respect the law of life and social development, that is, to respect history.
Due to historical and natural reasons, China's economic development within and between regions is very uneven. The economic and technological poverty alleviation in the eastern and central and western regions is very different, especially in poor areas. Active support measures will be taken to help poor areas and poor households get rich, accelerate economic development in poverty-stricken areas, and play an important role in strengthening social stability and unity, accelerating socialist construction, correctly handling ethnic relations, carrying forward revolutionary traditions, and consolidating national defense. The role and significance of poverty alleviation in building a harmonious society and enhancing the family ties of urban and rural residents is more prominent.
