New Journey Horn, China's New Development, New Opportunities for the World

"Now, the CIIE has become a window for China to build a new development pattern, a platform to promote high-level openness, and a globally shared international public product."

 

 

On November 4, President Xi Jinping delivered a speech at the opening ceremony of the Fifth China International Import Expo and pointed out that China's new development will continue to provide new opportunities for the world and promote the construction of an open world economy.

 

 

The Fifth International Fair is the first major international exhibition held in China after the 20th National Congress of the Communist Party of China.

 

 

A set of figures confirm the power of China's opening up-more than 280 of the world's top 500 and industry leading enterprises participated in the Fifth Expo, with a "return rate" of nearly 90%; the world's four major grain merchants, ten major medical device enterprises and fifteen major pharmaceutical enterprises have all arrived; a series of "world first show", "Asia first" and "China first exhibition" have appeared.

 

 

Not long ago, when a member of the Standing Committee of the Political Bureau of the 20th CPC Central Committee met with Chinese and foreign journalists, General Secretary Xi Jinping stressed, "China's door to opening up will only get bigger and bigger. We will unswervingly deepen reform and opening up in an all-round way, unswervingly promote high-quality development, and create more opportunities for the world with our own development."

 

 

China's development cannot be separated from the world, and the world's development also needs China. The vigorous movement of "China's new development, new opportunities for the world" is playing.

 

 

"We must use openness to alleviate the difficulties of development, use openness to pool the power of cooperation, use openness to gather innovation, and use openness to seek shared blessings, so as to promote the continuous advancement of economic globalization, enhance the development momentum of all countries, and make development results more More equitable to benefit the people of all countries." At the opening ceremony of the Fifth China International Import Expo, President Xi Jinping spoke sonorously.

 

 

China has a population of more than 1.4 billion and middle-income groups above 0.4 billion. It imports about 2.5 trillion US dollars of goods and services every year, and the market scale is huge.

 

 

The market is an important resource, and the market of large countries is a global scarce resource.

 

 

From 9 square meters to 108 square meters to 200 square meters, from 0.38 billion yuan to 0.7 billion yuan to 1 billion yuan, the exhibition area of American essential oil company Dotley at the Expo has increased year by year, and the amount of purchase intention signed has increased year by year. McOwen, the relevant person in charge of dotley, could not hide his excitement. "Since participating in the Expo, dotley has developed at a high speed and grown together with the Expo."

 

 

△ On November 5, visitors experienced the application of "Yuan Universe" in the artificial intelligence zone of the 5th Expo.

 

 

With the deepening of high-quality development, the "magnetic force" of the Chinese market is more powerful.

 

 

"In recent years, China has accelerated its digital transformation and upgrading, which has led to the integration and development of new technologies. The great achievements in 5G, artificial intelligence, electric transportation, industrial Internet, intelligent manufacturing and other fields are obvious to all." Kang Liang, general manager of ABB (China) Co., Ltd., said that China has released new huge market potential and opportunities in the process of promoting high-quality development, and will continue to attract multinational companies to continue to expand investment and layout in China.

 

 

In August this year, Honeywell, a Fortune 500 company, and Honeywell, a Chinese power battery company, joined hands with Honeycomb Energy, to build a Honeycomb Energy digital factory by integrating product and technological advantages to achieve lean and automated industrial transformation and upgrading.

 

 

"As a'old friend' of the CIIE, we will rely on the open and efficient platform effect of the CIIE to continuously introduce leading innovations into China and promote local innovation to the world." Honeywell company related responsible person said.

 

 

General Secretary Xi Jinping pointed out in the report of the 20th National Congress of the Communist Party of China that relying on my country's ultra-large-scale market advantages, attracting global resource elements with a large domestic cycle, enhancing the linkage effect of two resources in the domestic and international markets, and improving the quality and level of trade and investment cooperation.

 

 

"The Chinese market is crucial" has become an international consensus. China's sincerity in taking the initiative to open its market to the world and sharing China's opportunities with other countries is injecting strong positive energy into the difficult recovery of the world economy.

 

 

In the welcome hall of the National Convention and Exhibition Center (Shanghai), the huge Chinese painting "Spring Breeze and Green River South Bank" conveys a clear message to the world with poetic Chinese elements: let the open spring breeze warm the world.

 

 

On November 4, President Xi Jinping emphasized at the opening ceremony of the Fifth China International Import Expo that China will promote all countries to share institutional opening opportunities.

 

 

On the 4th, when President Xi Jinping met with German Chancellor Scholz at the Great Hall of the People in Beijing, he pointed out: "China will unswervingly promote high-level opening up, adhere to the correct direction of economic globalization, continue to promote the construction of an open world economy, and expand The point of convergence of the interests of all countries."

 

 

The promise of a big country, a promise of a thousand dollars.

 

 

The opening commitment of the previous four CIIE sessions is reflected in the "Special Administrative Measures for Foreign Investment Access (Negative List)": in 2019, the requirement that domestic shipping agencies, cinemas construction and operation, and performance brokerage agencies must be controlled by the Chinese side will be canceled; In 2020, the requirement that the Chinese share ratio of automobile manufacturing enterprises (except special vehicles and new energy vehicles) shall not be less than 50% will be canceled in 2021, cancellation of securities, funds, futures, life insurance and other financial companies foreign shares ratio of not more than 51% and other restrictions.

 

 

Milk produced on Monday at a foreign ranch can be on the plane on Tuesday and directly to the table of Chinese consumers on Wednesday ...... As one of the first pilot enterprises of the innovative regulatory model of "inspection and release" separation and "border inspection and release" for trade facilitation, Roy, Global R & D General Manager of New Zealand's Newland Dairy, really felt the charm of "speed of entry. "This shows China's firm attitude to continuously optimize the business environment through determined reforms, innovative systems, and improved processes."

 

 

Over the past decade, China's institutional openness in rules, regulations, management and standards has been deepened. From the launch of the first negative list of foreign investment access in the pilot free trade zone in 2013, to the launch of the first negative list of cross-border service trade in Hainan in 2021, and then to the revision of the "Catalogue of Industries Encouraging Foreign Investment" many times, China is relaxing The level of institutional openness has been continuously improved by "subtraction" in market access and "addition" in preferential policies.

 

 

△ On October 15, the Marshall Islands "Arab Diher" freighter, carrying Spanish exhibits of the Fifth Expo, berthed at the fourth phase of Yangshan Deepwater Port.

 

 

Experts believe that institutional opening is based on the opening of regulations, rules, and standards. It has comprehensive, systematic, and stable characteristics. It is a higher-level and higher-level opening.

 

 

"Steadily expanding institutional openness in rules, regulations, management and standards", "promoting the building of a new type of international relations and deepening the expansion of a global partnership of equality, openness and cooperation", "firmly pursuing a mutually beneficial and win-win strategy of openness" ...... The word "openness" has appeared many times in the report of the Party's 20th National Congress, and "China's door to opening up will only get bigger and bigger" has brought warmth to the world economy.

 

 

On the new journey, China with surging development momentum and China with warm spring breeze will surely provide new development opportunities for the world.

 

 

One minute, what can happen?

 

 

The China-Europe train transported 3 TEUs of goods, 30 passengers and 7 TEUs of goods arrived at the destination through the Monnet Railway, the Karot Hydropower Station in Pakistan, which was built with the assistance of Chinese enterprises, generated electricity to meet the electricity needs of 5 million local people, and the total import and export volume between China and the countries along the "Belt and Road" reached 25.3 million yuan ...... Not long ago, this set of "one minute" data on social media, vividly presents the story of China's promotion of economic globalization.

Under the background of high-quality development, how will the road and bridge industry develop?

In the first year of the 14th Five-Year Plan, China's economy has entered a stage of high-quality development, transforming the mode of economic development, optimizing the economic structure, transforming the driving force of economic growth, and realizing the structural transformation from medium and low-end industries to medium and high-end industries is the theme of economic development for a long time in the future. With the gradual decline of the marginal utility of investment in economic pull, and the proposal of the new development pattern of "double cycle", China's economic growth drive is gradually changing from investment-driven to consumption-driven, therefore, the future investment growth rate of the construction industry will inevitably slow down further. As an important part of the construction industry, the road and bridge engineering construction industry plays a very important role in maintaining the normal operation of social production, circulation, distribution, and consumption, ensuring the sustained, rapid and healthy development of the national economy, improving people's living standards, and promoting the modernization of national defense. However, with the continuous improvement of the highway network and national and provincial highways, the market space of the road and bridge industry is under pressure, and the competition is becoming increasingly fierce. In the future, there are five main trends in the development of the road and bridge industry: First, industrial chain extension and related diversification are effective ways to deal with growth bottlenecks. The upstream and downstream expansion of the industrial chain includes the mining and manufacturing of upstream raw materials, downstream real estate, operation, and EPC construction general contracting. The related diversified development mainly extends to rail transit, water conservancy, environmental protection, maintenance engineering and other fields. Second, the concentration of the industry continues to increase, and market competition is further intensified. The market concentration of the construction industry is low and there are many players. However, with the further deepening of the marketization of the industry and the deterioration of the international environment, large and medium-sized enterprises such as central enterprises and provincial state-owned enterprises have begun to enter the city to seize the regional market and hinder the industry from breaking through. The influencing factors of geographical restrictions have been continuously weakened, the cross-regional competition of the industry has become increasingly significant, and the market concentration is expected to continue to increase. Third, the growth of the eastern market space is limited, and the western market has more room for development. With the low density of road network in the western region and the promotion of relevant policy factors such as the large-scale development of the western region and "Belt and Road Initiative", the investment in infrastructure construction in the western region is gradually strengthening and has become a key area for domestic highway construction. Fourth, intelligent transportation has become a new bright spot in the field of highway construction. Driven by technologies such as ultra-high-speed wireless local area network and 5G mobile communication, smart transportation will be greatly developed in the future. Fifth, the qualification reform promotes the road and bridge enterprises to enhance the degree of marketization and comprehensive strength. In March 2020, the Measures for the Administration of Engineering Cost Consulting Enterprises and the Measures for the Administration of Registered Cost Engineers proposed to lower the qualification threshold for cost enterprises. In July 2020, the Ministry of Housing and Construction issued the Framework of Qualification Standards for Construction Engineering Enterprises (Draft for Comments), proposing to significantly reduce the qualification categories and grades of enterprises. Lowering the entry threshold for the construction industry will further promote road and bridge enterprises to change the traditional concept of "waiting and relying on, really improve the construction ability, technical strength and management ability.

Analysis and Solution Summary of Common Faults of Smearing Machine

1. Smoke from the smoothing machine when working Check the trowel machine to check whether there is too much oil. If there is too much oil, release part of it. It can also be that the piston is broken and severely worn and will burn the oil. If it is damaged, it needs to be replaced in time. Check the engine. If the engine is not faulty, it may also be that there are too many impurities in the oil. The oil is very important. Try to choose high-quality oil. When buying, you must pay attention to prevent buying inferior fake oil. 2. How to level the chassis screws of the smoothing machine First replace 4 new blades and put the trowel in a particularly flat place. Then remove the shift fork and visually inspect whether the heights of the four screws are consistent. If conditions permit, measure them with a ruler. If the heights are inconsistent, adjust them to be consistent. When the gland is gently shaken, if there is no shaking, the debugging is proved successful. Put some butter on the top of the screw to prevent wear. 3. The wiping machine always stalls Observe whether the oil level is normal and whether the oil is too little. Some machines have their own oil protection system, which will automatically turn off when there is a shortage of oil. There is also the fact that after the remote flameout switch and the flameout switch of the machine are disconnected one by one, if the flameout phenomenon does not occur again, it means that there is grounding in that part. Just check and eliminate it carefully. 4. The engine of the trowel is normal, but the trowel is not moved. If there is no problem with the engine, it is caused by the wrong belt type or the belt is too long. If there is still an abnormality, it can be handled by changing a clutch. 5. The gasoline polish machine was blistered First clean the carburetor, let the spark plug be removed to see if there is water in the cylinder head. If there is water, pull the disk several times to drain the water. Try again after changing the oil to see if it is normal. 6. The smoothing machine cannot rotate Reason: The blade may be deformed; the motor bearing is broken; the motor bracket is not fixed well; there is a problem in use.

Method of polishing and grinding

Method of polishing grinding: Grinding is the grinding tool (hereinafter referred to as the grinding tool) surface embedded abrasive or coated abrasive and add lubricant, under certain pressure, the tool and the grinding tool contact and do relative movement, through the abrasive action, from the workpiece surface cut a layer of very thin chip, so that the workpiece has a precise size, accurate geometry and high surface roughness. Its essence is to use free abrasive particles to carry out micro-cutting including physical and chemical comprehensive effects on the surface of the workpiece through the grinding tool. Features:(1) In mechanical grinding, the machine tool-tool-workpiece system is in an elastic floating state. (2) The workpiece to be ground is not subject to any force and is therefore in a free state. (3) The speed of the grinding movement is usually below 30 m/min, which is about 1% of the grinding speed. (4) When grinding, only a very thin layer of material can be cut off, so the heat generated is less, the processing deformation is small, and the surface deterioration layer is also thin. (5) There is residual compressive stress on the grinding surface, which is beneficial to improve the fatigue strength of the workpiece surface. (6) The operation is simple and generally does not require complicated and expensive equipment. (7) Adaptability is good. (8) grinding can obtain very low surface roughness. 1. Fluid polishing Fluid polishing is to rely on high-speed flow of liquid and abrasive particles to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, fluid power grinding. Fluid power grinding is driven by hydraulic pressure, The liquid medium carrying the abrasive particles is caused to flow back and forth at high speed over the surface of the workpiece. The medium mainly uses special compounds with good flowability at lower pressure. (polymer-like substance) and mixed with abrasive, abrasive can be used silicon carbide powder. 2. Mechanical polishing Mechanical polishing is a method of polishing a smooth surface by cutting and plastic deformation of the surface of the material to remove the convex part after polishing, Generally use oilstone, wool wheel, sandpaper, etc., mainly manual operation, special parts such as the surface of the rotary body, Auxiliary tools such as turntables can be used, and the method of super-lapping can be used for high surface quality requirements. Super lapping is a special abrasive tool, In the polishing liquid containing abrasives, it is tightly pressed on the surface of the workpiece to be processed for high-speed rotating motion. Using this technology, the surface roughness of Ra0.008 μm can be achieved, which is the highest among various polishing methods. Optical lens molds often use this method. 3. Ultrasonic polishing The workpiece is placed in the abrasive suspension and placed together in the ultrasonic field, relying on the oscillation of the ultrasonic, The abrasive is ground and polished on the surface of the workpiece. Ultrasonic machining macro force is small, will not cause deformation of the workpiece, but tooling production and installation is difficult. Ultrasonic machining can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is applied to stir the solution, The dissolution products on the surface of the workpiece are separated, and the corrosion or electrolyte near the surface is uniform; Ultrasonic cavitation in the liquid can also inhibit the corrosion process, conducive to surface brightening. 4. Electrolytic polishing The basic principle of electrolytic polishing is the same as chemical polishing, that is, by selectively dissolving the small protruding parts of the surface of the material, Make the surface smooth. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better. The electrochemical polishing process is divided into two steps: (1) Macroscopic leveling dissolution products diffuse into the electrolyte, and the geometric roughness of the material surface decreases, Ra> 1μm. (2) micro light level anode polarization, surface brightness, Ra <1μm. 5. Fluid polishing Fluid polishing is to rely on high-speed flow of liquid and abrasive particles to wash the surface of the workpiece to achieve the purpose of polishing. Commonly used methods are: abrasive jet processing, liquid jet processing, fluid power grinding. Fluid power grinding is driven by hydraulic pressure, The liquid medium carrying the abrasive particles is caused to flow back and forth at high speed over the surface of the workpiece. The medium is mainly made of special compounds (polymer-like substances) with good flowability at lower pressure and mixed with abrasives, The abrasive may use silicon carbide powder. 6. Chemical polishing Chemical polishing is to make the surface of the material in the chemical medium micro convex part of the concave part of the preferential dissolution, A smooth surface is thus obtained. The main advantage of this method is that it does not require complex equipment and can polish workpieces with complex shapes, Many workpieces can be polished at the same time with high efficiency. The core problem of chemical polishing is the preparation of polishing solution. Surface roughness obtained by chemical polishing Generally, it is several 10 μm. 7. Magnetic grinding and polishing Magnetic grinding and polishing is the use of magnetic abrasive under the action of a magnetic field to form an abrasive brush to grind the workpiece. This method has high processing efficiency, Good quality, easy control of processing conditions, good working conditions. With suitable abrasives, the surface roughness can reach Ra0.1 μm. The polishing in plastic mold processing is very different from the surface polishing required in other industries, Strictly speaking, the polishing of the mold should be called mirror processing. It not only has the very high request to the polishing itself but also to the surface flatness, There are also high standards for smoothness and geometric accuracy. Surface polishing is generally only required to obtain a bright surface. The standard of mirror processing is divided into four levels: AO = Ra0.008μm, A1 = Ra0.016μm, A3 = Ra0.032μm, A4 = Ra0.063 μm, due to electrolytic polishing, fluid polishing and other methods are difficult to accurately control the geometric accuracy of the part, The surface quality of chemical polishing, ultrasonic polishing, magnetic grinding polishing and other methods can not meet the requirements, so the mirror processing of precision molds Or mainly mechanical polishing.

What does the floor grinder floor grinder inverter display oL2 mean? Why can't the machine start? How to solve?

The situation is as follows: 1. The ground is very uneven, the resistance of the grinding disc is large, and the motor load is too heavy. 2. If this situation occurs when the new machine is used for the first time, it means that the governor has been adjusted to the fastest speed position, or the new grinding plate (block) Not open rough pressure on the rough hard surface, resulting in a large disc resistance, motor load is too heavy. 3. If the gearbox is repaired and the machine is initially tested like this, it may be that the gear assembly is not smooth and too tight, causing the grinding disc to rotate manually. It is not smooth, or the motor shaft and the center gear are not concentric after the motor is fixed during assembly, that is, the rotation is not concentric, which makes the electricity The rotation of the rotor is blocked and Caton occurs. Corresponding solution: 1, the machine up, move to a relatively flat ground area grinding, and then slowly cut into the uneven ground area, or use Other small grinding disc machinery will ground the rough surface of the potholes slightly smooth, and then use the machine to grind. 2. Roughen the grinding piece (block) on the cement floor. Press down on the armrest and raise the starter of the machine (make the grinding disc slightly off the ground). The machine (grinding disc) can be slowly landed. 3. Reassemble the gear or reassemble the motor to make the gear and the grinding disc rotate smoothly. After inserting the motor shaft into the central gear Concentric, suspend the motor and the box and energize the motor to start the motor, so that the motor, gear and grinding disc rotate smoothly. After shutdown, hand Rotate the grinding disc smoothly.
