Panel classification and light transmittance of photovoltaic curtain wall

From the perspective of power generation materials for curtain wall panels, there are films and crystalline silicon. The crystalline silicon photovoltaic curtain wall is divided into monocrystalline silicon and polycrystalline silicon, and the double glass interlayer is the main manifestation. In view of the power generation efficiency and the current situation and trend of the industry development, the early application of crystalline silicon photovoltaic curtain wall is mainly polycrystalline silicon. At present, the mainstream mode of crystalline silicon photovoltaic curtain wall is monocrystalline silicon.   The thin-film photovoltaic curtain wall is the most mainstream application mode. From the perspective of power generation materials, it can be further subdivided into cadmium telluride, copper indium gallium selenium, perovskite and other sub categories. In view of the flexibility and comprehensive factors such as color, light transmission, texture, weak light, customization, etc., at present, the cadmium telluride thin-film photovoltaic curtain wall is the most widely used, most suitable for the scene, and capable of large-scale commercial mass production.   From the perspective of light transmission, it can be classified into light transmission type, semi light transmission type, non light transmission type, etc. The application of crystalline silicon photovoltaic curtain wall in the direction of glass curtain wall, due to the functional requirements of light transmission and even perspective, is usually presented by replacing the outer glass of glass curtain wall with double glass sandwich modules. Because crystalline silicon cells do not have light transmission, the light transmission of double glass sandwich modules comes from the gap between crystalline silicon cells (the width of the gap can be adjusted relatively flexibly). When the gap is wide, it will show a certain perspective effect. From the perspective of the overall effect of light transmission and perspective, due to the obvious characteristics of low light transmission and poor uniformity (the term "uniformity" is provided by the industry encyclopedia), it is appropriate to classify such products and applications as semi transparent photovoltaic curtain walls.   For the application of crystalline silicon photovoltaic curtain wall in the direction of solid wall of building exterior wall, because there is no need for light transmission function, usually manufacturers will carry out artistic treatment of color, texture and pattern in the interlayer of double glass sandwich module. This kind of application basically does not have light transmission and belongs to non light transmission photovoltaic curtain wall. The thin film photovoltaic curtain wall shows diversified characteristics in terms of light transmission. Take the cadmium telluride thin film as an example: the light transmission performance comes from the gap space when the power generation thin film is etched to form a battery string, which plays an important role in light transmission, perspective, light transmission and other properties. Due to the artistic treatment and personalized customization of color, texture, pattern, etc. according to the design requirements, it has produced a variety of manifestations such as light transmission, semi light transmission (or partial light transmission), and light consumption, which also makes the film photovoltaic curtain wall more widely used and more adaptable.   Thin film power generation materials also have technical routes and products based on metal plates. The light impermeability of metal plates determines that such photovoltaic curtain walls have the characteristics of non light transmission, which is only applicable to the application scenario of replacing the external skin of solid walls of building exterior walls.   To sum up, from the perspective of light transmittance, there are two types of crystalline silicon photovoltaic curtain walls: semi transparent and non transparent; There are three types of thin-film photovoltaic curtain walls: light transmitting, semi light transmitting and non light transmitting.

Sea freight collapses, "order shortage" spreads globally

The recent wildly declining global ocean rates have impacted a number of new and smaller players in the liner shipping industry, as their current earnings are not sufficient to cover the sky-high charter rates they have committed to. Allseas reportedly decided to cut capacity as freight volumes fell and Asia-Europe rates dropped 25% from May to an average of just around $7,700/teu. In addition, the large number of new ships launched by shipping giants has exacerbated the gap between supply and demand. Kang Shuchun said, last year's abnormally high freight rates let many shipping companies earn a lot of money, some of the large shipping companies will profit into the new shipbuilding only, and in the epidemic before, the global shipping capacity has been higher than the volume. The Wall Street Journal quoted energy and ship consulting firm Braemar, said the next two years will have a series of new ships launched, is expected to next year and 2024 fleet net growth rate of more than 9%, while the year-on-year growth rate of container cargo volume in 2023 will turn negative, which will make the global capacity and volume imbalance between the further intensification. The Wall Street Journal believes that due to the many uncertainties in the international political and economic situation, shipping rates are likely to fall further in the remainder of this year and into next year. From the current global economic situation, shipping freight downward trend is certain, but to what extent and when the fall is difficult to conclude.

Application of LED in architectural curtain wall

With the rapid development of China's economy, various characteristic buildings in the city have come into being. In addition to the function of the building itself, the appearance of the characteristic charm, the night lighting of the building, lighting media also put forward higher requirements. LED because of its energy saving, environmental protection, long service life, high efficiency and other incomparable advantages over traditional light sources, in recent years in the building curtain wall lighting has been widely used. LED media building curtain wall will be the integration of sound, image, video, etc., to give people a A peculiar artistic enjoyment. LED media architectural curtain wall can be used to shape the urban space, thus changing the overall image of the city. LED glass has the following characteristics: High permeability: LED glass has a permeability rate of 99% and a light transmission rate of 80%, which does not affect the line of sight and lighting; High stability: the use of light drive separation control method, greatly enhancing the service life of LED lamp beads and the stability of LED photoelectric glass, and its maintenance costs are low; convenient installation: do not damage the building structure and glass curtain wall structure, and the building curtain wall structure to achieve a perfect fit, the installation method and ordinary glass curtain wall consistent, partial replacement of glass curtain wall. LED glass that can be used as a glass curtain wall decorative building effects, but also greatly enhance the artistic expression of the night image of the building. So LED glass has been more widely used in architectural curtain walls in recent years. LED media building curtain wall is a new form of urban art, as a combination of science and art of modern urban landscape. At present, the city of various types of buildings in the LED media building curtain wall mostly use dynamic screens, display video, display advertising, urban information and humanities and art, etc., to give people a strong visual impact. Along with the rapid development of electronic information technology, advanced multimedia technology, LED media building curtain wall in the city is commonly used to improve the city's cultural and artistic atmosphere. The country strongly advocates green lighting, green indicators in the architectural curtain wall lighting project is: the choice of energy-efficient light sources; light clear LED in the application of architectural curtain wall, more to meet the requirements of energy efficiency, Although there are certain technical means of anti-glare and light pollution, but still produce - certain glare and light pollution. But we believe that with the The development of modern science and technology, the building curtain wall new decorative lighting will continue to progress, and one day will achieve the true meaning of green color lighting.

460 Meters! Suzhou Zhonghai Super Tower, The Tallest Curtain Wall Apartment Building in China

In Suzhou, one of China's most livable cities, a new 460-meter tall landmark building will rise quietly in the central business district on the western shore of Jinji Lake, forming a unified urban architectural complex facing Jinji Lake, along with the Gate of the East, Suzhou South Central Center and Suzhou Central Plaza.   The facade of Suzhou Zhonghai Super Tower utilizes sustainable design elements, including photovoltaic panels integrated throughout the podium and high-performance glass panels, effectively reducing the building's reliance on heating and air conditioning.   The podium, in the form of an open ride, is connected to the nearby Suzhou Center by a pedestrian promenade on the east side, with a series of glass light roofs that bring natural light and views of the tower into the commercial spaces on the first floor.   At the same time, the undulating facade, composed of metal grilles and glass curtain walls, creates a three-dimensional light and shadow effect of water ripples for the tower, using the light and shadow at different times of the day, angles and weather. In addition, the façade shape is inspired by the ancient scrolls that unfold slowly, expressing respect to this thousand-year-old cultural and historical city.   Suzhou China Shipping Super Tower is expected to be completed in 2027. The project will use low-carbon building materials, reduce water and energy use throughout the building system, meet strict indoor air quality requirements, and meet top industry green building certifications such as LEED Platinum, Green Building Three Star, CABEE Ultra Low Energy Building, WELL certification, and Healthy Building Label.   In addition, according to the design plan, the project façade will adopt "golden" glass curtain wall throughout, which can also be said to be another ceiling of value by the Jinji Lake.

1500 Tons Steel Truss Structure Members Exported to Oceania

1500 Tons Steel Truss Structure Members Exported to Oceania on August, 2022.   A steel truss refers to a truss made of steel. In the roof structures, crane beams, bridges and hydraulic gates of industrial and civil buildings, steel trusses are often used as the main load-bearing components. All kinds of towers, such as mast towers, TV towers and transmission line towers, are commonly used space steel trusses composed of three-sided, four-sided or multi-sided planar trusses.   The most commonly used is the plane truss, which is essentially a lattice beam under the action of lateral loads. Compared with solid-web steel beams, steel trusses are characterized by chords instead of flanges and webs instead of webs. Rods and chords are connected to each other; sometimes the members can be welded (or otherwise connected) directly to each other without the use of gusset plates. In this way, the bending moment of the plane truss as a whole is expressed as the axial compression and tension of the upper and lower chords, and the shear force is expressed as the axial compression or tension of each web member.   Application: Trusses are widely used in steel structures, such as roofs (roof trusses, etc.) and crane beams (ie crane trusses) of industrial and civil buildings, bridges, cranes (its towers, beams or booms, etc.), hydraulic gates, In offshore oil production platforms, steel trusses are often used as the main components of load-bearing structures. Various types of steel grids, which are widely used in the roof structure of large-span public buildings, belong to space steel trusses. Various types of towers, such as TV, power transmission, drilling, crane towers and mast towers, often use space steel trusses composed of three-sided, four-sided or multi-sided planar trusses.   Looking forward to your visit and inquiry.

The outer wall of the 218-meter Changsha Telecom Building caught fire. Who is to blame?

On the afternoon of September 16, 2022, a fire broke out in the China Telecom Building in the urban area of Changsha, Hunan Province. Thick smoke billowed from the scene, and dozens of floors burned violently.   The telecommunications building was built in 2000 and is located in the East Second Ring Road of Changsha City. It was the first building in Changsha to exceed 200 meters with a height of 218 meters.   Now, after a few minutes of fire, the building has turned into such a "black" color... Whether it is the owner, or the design, construction unit and material suppliers, or practitioners in the door, window and curtain wall industry, they all feel a while heartbroken.   In high-rise building fires, the fire tends to spread rapidly upwards in a short period of time, which is due to the "chimney effect" formed by high-rise buildings! The phenomenon of enhanced convection of air.   In recent years, there have been quite a number of high-rise and super-high-rise curtain wall buildings whose exterior wall materials, design and construction do not meet the requirements of current regulations. When a fire occurs, there is a risk of spreading throughout the building, and more attention needs to be paid!   At the same time, behind the accident again and again, is our thinking on the design height of the future building curtain wall and the selection of external wall insulation materials!
