The Best Era of Solar Photovoltaic Power Generation

The Best Era of Solar Photovoltaic Power Generation

Nowadays, in the context of global climate change, deterioration of human ecological environment, and shortage of conventional energy resources, solar photovoltaic power generation is highly valued worldwide. The solar cell wing is the energy source of Shenzhou 13: At 9:56 on April 16, the Reentry capsule of Shenzhou 13 manned spacecraft landed successfully in the Dongfeng landing site. The Shenzhou 13 manned flight mission was a complete success, and the three astronauts also returned safely. Since last year's "check-in" to the China Space Station, the Shenzhou 13 flight crew has lived in the Tianhe core module for more than 180 days. Living in orbit for 6 months, in addition to multiple supply of transport rockets, the first use of a large area retractable flexible solar cell wing has also become a winning weapon to ensure the normal operation of all equipment in the cabin and maintain the normal life of astronauts. This is the first time China has adopted flexible solar wings as the energy source for spacecraft. Flexible solar wings combine four new technologies: large-scale lightweight, high reliability with repeated deployment and retraction, long life in orbit for 10 years in low orbit, and high load-bearing capacity with both rigidity and flexibility. A single wing can provide 9kW of power to the space station. You know, the Dong Fang Hong 1 satellite we know well used chemical batteries in those days.

Five aspects to promote high-quality development of photovoltaics during the 14th Five Year Plan period

Five aspects to promote high-quality development of photovoltaics during the 14th Five Year Plan period

According to Ren Yuzhi, the "14th Five Year Plan" for the development of renewable energy has been officially issued and will be made public in the near future. During the 14th Five Year Plan period, the renewable energy industry will deeply implement a new energy security strategy, adhere to the overall tone of seeking progress while maintaining stability, anchor carbon peak and carbon neutrality goals, take high-quality leapfrog development as the theme, improve quality and efficiency as the main line, and reform and innovation as the driving force, promote the large-scale, high proportion, market-oriented, and high-quality development of renewable energy, and effectively support the construction of a clean, low-carbon, safe and efficient energy system. Overall, the National Energy Administration promotes the development of new energy in four aspects: optimizing regional layout, supporting development with major bases, leading development with demonstration projects, and implementing development with action plans. For the development of photovoltaics, the National Energy Administration will adhere to the principle of simultaneous development of five aspects, centralized and distributed, on-site and external consumption, complementary development of single variety energy with other multiple varieties, and simultaneous development of single and comprehensive scenarios, further promoting the utilization of photovoltaic power generation on a larger scale, in more scenarios, in more modes, and at a higher level.

Aluminum profile application: What are the highlights of all aluminum body besides its lightness?

Aluminum profile application: What are the highlights of all aluminum body besides its lightness?

Aluminum alloy does not refer to a single alloy, but there are actually quite a few categories. The common rule in the world is to use a condition code with four digits and a letter to distinguish the types of aluminum alloy. For example, the commonly used 6063-T5 in the construction industry, where the top number is 1, which represents pure aluminum with a purity higher than 99%, 2-8 represents alloys composed of aluminum and copper, manganese, silicon, magnesium, magnesium+silicon, zinc, and other elements, and 9 is a backup group. The following numbers are primarily used for differentiation and will not elaborate on specific logic. In summary, each formula of aluminum alloy has a unique label corresponding to its unique characteristics.

How to improve the use of industrial aluminum profiles, aluminum products, and aluminum alloy products

How to improve the use of industrial aluminum profiles, aluminum products, and aluminum alloy products

1. Insufficient structural strength, industrial aluminum profiles can be thick or thin, with varying cross-sectional sizes. If thin profiles with small sections are used to produce aluminum profiles with high load-bearing strength. The service life will be greatly discounted. This is like asking a thin and weak child to do the physical work of an adult, which will eventually lead to exhaustion. So it is very important to choose industrial aluminum profiles with appropriate strength as raw materials. 2. The design is unreasonable. The design of an aluminum profile product is very important, considering the convenience of human use and even load. If light materials are used in areas with high stress, and heavy materials are used in areas with low stress, it would be twice the result with half the effort. 3. Improper use of aluminum profile accessories. Industrial aluminum profile products mainly rely on the assembly of specialized aluminum profile accessories, and there is no need to save any parts that need to be used. Ordinary corner pieces should never be used where strong corner pieces are required. 4. The quality of other accessories needs to be guaranteed, such as the countertop of the workbench. Nowadays, anti-static countertops are generally used. The countertop not only needs to have anti-static function, but also needs to be wear-resistant and easy to clean. The aluminum profile frame is not easily damaged, and if the countertop is damaged, it is also very troublesome to replace.

Industrial aluminum profiles are the focus of future aluminum industry development

Industrial aluminum profiles are the focus of future aluminum industry development

After oxidation, the surface of industrial aluminum profiles has a very beautiful appearance and is resistant to dirt. Once coated with oil stains, it is very easy to clean. When assembling into products, different specifications of profiles are used according to different load-bearing requirements, and supporting aluminum profile accessories are used. Welding is not required, which is more environmentally friendly. Moreover, installation and disassembly are lightweight, easy to carry, and extremely convenient to move. Industrial aluminum profiles are an alloy material mainly composed of aluminum. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the proportion of added alloys varies, resulting in different mechanical properties and application fields of industrial aluminum profiles produced. Generally speaking, industrial aluminum profiles refer to all aluminum profiles except for building doors and windows, curtain walls, indoor and outdoor decorations, and building structures.

Development status of wood grain technology for industrial and architectural aluminum profiles

Development status of wood grain technology for industrial and architectural aluminum profiles

With the rapid development of the domestic economy, people's aesthetic views have also changed. Nowadays, people believe that the color of white and bronze doors and windows aluminum materials is monotonous and not rich and colorful, and therefore require multiple colors, such as green, yellow, red, blue, etc. Only green can be divided into six types. During the extrusion process of aluminum, if the extrusion mold is not very good or the mold compresses aluminum too much, the surface of the aluminum material will produce extrusion marks, which may be uneven when touched by hand. In order to make the surface of the aluminum material smooth and flat, and not touch the extrusion marks, the aluminum factory usually uses alkaline water to corrode and remove the extrusion marks first. Sandblasting technology is an advanced method for surface treatment of aluminum profiles in recent years, which uses specially designed sand high-speed spraying to remove extrusion marks on the surface of aluminum profiles. In fact, several well-known domestic aluminum factories, due to their excellent molds, advanced equipment and technology, have no extrusion marks and do not require sandblasting for aluminum extrusion exports.
