European Airbus casts a vote of confidence in China!

Xinhua All-Media + | “+1”: Airbus Europe Casts a Vote of Confidence in China! Xinhua News Agency, Tianjin, November 9 (Reporter Liang Zi) — On November 9, the Airbus A321 aircraft officially began production at the Asia final assembly line for the A320 family located in Tianjin. The first A321 aircraft is expected to be delivered in the first quarter of next year. From “320” to “321,” the mass production of one of Airbus’s most popular models in China is not just a simple addition of a “1” to its model name—it’s also a vote of confidence cast by foreign investors, led by Airbus Europe, in China. The A321 is one of the models in Airbus’s A320 family. This model can meet the demands of both domestic hub-and-spoke air routes and better serve popular routes along the Belt and Road Initiative countries. At Airbus’s Tianjin final assembly line, the first Airbus A321 aircraft has started final assembly. Since the outbreak of the pandemic, the global aviation industry has been severely impacted. According to IATA’s forecast, the global aviation industry will continue to suffer losses in 2022. Against this backdrop, China’s “14th Five-Year Plan for Civil Aviation Development” projects that passenger traffic will reach 930 million by 2025, and the average number of air trips per Chinese resident will rise from 0.47 in 2019 to 0.67. In July of this year, several Chinese airlines placed orders with Airbus for a total of 292 A320NEO series aircraft, to replace retired planes and expand their fleets. Airbus stated that, viewed from a single country perspective, China will remain the world’s largest market for new aircraft demand over the next 20 years. Not only in the aviation industry, but according to the 2022 China Business Environment Survey Report released by the American Chamber of Commerce in China, 60% of member companies listed China as one of their top three investment destinations for near-term global investment plans, and two-thirds of member companies plan to increase their investments in China this year. Foreign-invested enterprises are “voting with their feet” and “voting with their investments,” driven by stable expectations of China’s steady economic growth and a vibrant consumer market. A set of figures speaks volumes: From 2013 to 2021, China’s average contribution to global economic growth reached 38.6%, surpassing the combined contribution of the G7 countries; the share of high-tech manufacturing and equipment manufacturing in the value-added of industrial enterprises above designated size rose from 9.4% and 28% in 2012 to 15.1% and 32.4% in 2021, respectively. Foreign investors’ confidence in China also stems from China’s firm commitment to green development. As the 27th Conference of the Parties (COP27) to the United Nations Framework Convention on Climate Change is underway in Sharm el-Sheikh, Egypt, China continues to firmly implement its national strategy for actively addressing climate change, establishing a “1+N” policy framework for peaking carbon emissions and achieving carbon neutrality, and making a series of new deployments and arrangements. Guided by the “dual-carbon” goals, China has set long-term targets for achieving carbon-neutral growth in commercial aviation by 2035 and gradually bringing airport carbon emissions onto a peak plateau. It has also specified binding reduction targets for airline fuel consumption and carbon dioxide emissions during the 14th Five-Year Plan period. Through deep integration with Chinese enterprises, foreign companies’ green technology innovation capabilities have been put into practice. In September of this year, Airbus used sustainable aviation fuel in China for the first time, and it will be used for delivery flights from Airbus’s Tianjin facility... Xu Gang, Airbus Global Executive Vice President and CEO of Airbus China, said that despite the ongoing pandemic, Airbus has never slowed down its pace of development in China. The launch of the A321 model’s production in Tianjin demonstrates Airbus and European companies’ confidence in China’s economy and Chinese market. With advantages such as a complete industrial chain and supply chain, well-developed infrastructure, and a concentration of high-tech talent, China—pursuing a mutually beneficial, win-win, and open development strategy—will surely attract even more global confidence that goes beyond simply adding a “1.”

What are some common industrial cleaning methods?

Saturated Steam Method Dry-Ice Method Chemical Method Water Treatment Method Ultrasonic Method Principle Utilizing the high temperature of saturated steam and externally applied high pressure, this method cleans oil stains and contaminants from part surfaces by vaporizing and evaporating them. At the same time, it can also clean even the tiniest gaps and holes, effectively stripping away and removing oil stains and residues, thereby meeting requirements for high efficiency, water conservation, cleanliness, and dryness. Dry ice particles have an extremely low temperature (-78℃), giving them unique thermodynamic properties. When dry ice particles are impacted onto the surface of the object to be cleaned by compressed air, they rapidly sublimate, expanding in volume nearly 800 times within a few milliseconds. Simultaneously, they exchange heat with the surface of the part being cleaned, achieving the goal of cleaning the part’s surface. By adding organic or inorganic cleaning agents to the interface of the equipment being cleaned, this method disperses and removes stubborn scale, oily deposits, biological sludge, and other difficult-to-dissolve substances. At the same time, these agents react chemically to form complexes or water-soluble salts, thus accomplishing the cleaning objective. Using water as the medium, specialized equipment systems generate multiple high-pressure water jets at various angles and intensities, thoroughly cutting, breaking, compressing, and flushing scale, adherent deposits, and blockages inside the equipment to achieve the desired cleaning effect. Employing ultrasonic vibrations at frequencies ranging from tens of thousands to hundreds of thousands of cycles per second, ultrasonic waves propagate through liquids. When the energy exceeds 0.1 W/cm², the liquid molecules are torn apart, forming cavitation bubbles. As surrounding pressure increases, these cavitation nuclei are further collapsed. The collapse of these cavitation nuclei generates powerful shock waves that release tremendous energy, thereby detaching impurities from the surface of objects and achieving the cleaning purpose.

What should I do if the high-pressure washer’s hose is clogged?

When using cleaning equipment, to achieve even more thorough cleaning results while reducing water consumption and enhancing cleaning efficiency, it’s essential to ensure operational stability and meet stringent standards for an environmentally friendly cleaning process. This can be accomplished by adjusting the impact pressure and water flow rate appropriately to maintain a balanced cleaning performance. Regarding the degree of reaction between the equipment and the pipelines, using a high-pressure washer can significantly improve cleaning effectiveness. In particular, this approach enhances the system’s responsiveness to potential malfunctions. But what if the pipeline becomes clogged—how should we address that issue? 1. Replace the pipeline with a larger-capacity one Pipeline blockages can result from various factors. When the pipeline’s internal volume is relatively small, this can severely affect the fluid flow and its overall performance. Therefore, replacing the existing pipeline with a new one that has a larger capacity is often the best solution. In designing the new pipeline, it’s crucial to select a configuration that accommodates a greater water flow capacity. 2. Use cleaning agents to resolve blockages During the operation of high-pressure washers, nozzle clogging can occur due to accumulated debris or other obstructions. Depending on the severity of the blockage, applying a suitable cleaning agent can effectively dissolve the buildup and restore smooth water flow through the pipeline.

Advantages of dry ice cleaning machines

As for the term “dry ice cleaning machine,” I’m sure many of you feel both familiar and unfamiliar with it. That’s because most people recognize dry ice—after all, dry ice has a wide range of applications in daily life. In industries such as catering, wedding services, pharmaceuticals, cold-chain logistics, and e-commerce, you’ve probably heard about dry ice to some extent. Yet, when it comes to dry ice cleaning machines themselves, many people remain unclear about their specific cleaning applications. So, let’s have Meitengqi’s editor explain exactly what a dry ice cleaning machine is! Although dry ice cleaning machines are still considered a relatively niche service category in China, in some Western countries, they’ve been using dry ice to clean oil stains and grime from surfaces in both civilian and industrial sectors for decades. The technology was first applied to removing the outer coating of U.S. space shuttles, and gradually expanded to cleaning equipment across various industries. Thanks to its excellent cleaning performance—quickly and efficiently removing surface contaminants without leaving any residue—over 80% of stain-cleaning operations in these countries now rely on dry ice cleaning. In recent years, an increasing number of domestic Chinese companies have also started adopting dry ice cleaning to remove stains from industrial molds. The principle behind dry ice cleaning is that compressed air accelerates dry ice pellets, propelling them onto the surface of the object to be cleaned. Due to the extremely low temperature of dry ice (-78.5°C), it rapidly freezes and hardens any adhering substances, making them brittle. At the same time, the dry ice pellets penetrate deep into the surface of the material that’s been made brittle. As the dry ice sublimates and its volume expands rapidly, it creates an explosive force from within, effectively blasting away the contaminants from the surface. The entire process relies entirely on physical properties, so there’s no need to worry about any damage or freezing of the equipment.

Precautions for Industrial Vacuum Cleaners

1. Promptly remove any debris from the dustbin and all vacuum attachments. Be sure not to operate the device with wet hands to avoid electric shock. 2. Check the power cord and plug for any damage. After use, coil the power cord neatly and wrap it around the machine. 3. After finishing work, inspect the air inlet for blockages or debris; if any are found, clean them promptly. 4. Handle the machine gently during use—do not subject it to external impacts or forceful collisions. 5. When cleaning the machine, use a damp cloth lightly moistened with water or a neutral detergent. Never immerse the main unit head in water for cleaning. Do not use gasoline, banana oil, or similar substances, as these could cause the casing to crack. 6. Avoid running the machine continuously for extended periods. Limit continuous operation to no more than 2 hours; otherwise, it may shorten the machine’s lifespan. 7. With prolonged use, the filter mesh can become clogged, leading to reduced suction power. To prevent this drop in suction, regularly wash the filter mesh and dust bag with water. 8. If the main unit overheats, emits a burning smell, or displays unusual vibrations or noises, promptly take it for repair—do not continue using it under such conditions. 9. Do not repeatedly bend or flex the hose excessively, and avoid stretching or twisting it beyond its limits.
