The fifth generation of polyurethane low-carbon energy-saving Windows opens a new era of doors and Windows

As China proposes to achieve carbon peak in 2030 and carbon neutrality in 2060, it is a once-in-a-lifetime opportunity for the door and window industry to put forward higher requirements for energy-saving design indicators of doors and Windows, ultra-low energy buildings and near-zero energy buildings will also have more applications to promote the innovation and development of doors and Windows enterprises and make the industry achieve healthy development. Therefore, glass fiber reinforced polyurethane profiles with thermal insulation, light weight, high strength, good fire resistance and durable and non-deformation characteristics have been highly concerned in the door and window industry, known as the revolutionary material innovation of the door and window industry.

From 2021 to 2022, the development of wind power market is relatively depressed, the data of the wind energy Professional Committee of the China Renewable Energy Society show that: in 2022, the national new wind power hoisting capacity fell by about 11% year-on-year, of which offshore wind power fell by more than 60% year-on-year.

How to design the photovoltaic bracket in different scenes

For residential applications, the focus is on adapting the roof structure and ensuring the stability of the structure; For commercial applications, the safety and adaptability of the structure need to be considered; For agricultural applications, emphasis is placed on the ability and efficiency of PV modules to share space with crops.

Lightweight | Finnish composite manufacturers will provide lightweight composite profiles for Chinese bus manufacturers

"After decades of refinement of the pultrusion production process, the composite pultrusion production process can produce complex geometric profiles that are comparable in strength to conventional aluminum while weighing much less." At the same time, the finished profile has a smooth surface and requires no further processing."

2019-2023 Global new PV equivalent annual emissions reduction of 1.1 billion tons, the largest contribution from China

From 2022 to 2023, global solar PV capacity additions increased by more than 80% to a record 420 GW. In China, despite the phasing out of government subsidies for utility, commercial and industrial-scale PV projects, new solar PV installations grew 2.5 times, accounting for an unprecedented 62% of new global additions. Since December 2022, the rapid expansion of China's photovoltaic manufacturing industry has reduced the cost of photovoltaic modules by 50%, improving the competitiveness of solar PV.

Burst! The price of glass has gone up...

The price of glass fiber has risen!According to the feedback of the first line of news, the price of sheet yarn and felt yarn in the subdivision of yarn was suddenly pulled up, with an increase of 100-200 yuan/ton. In addition to the rise of the giants, small factories have also heard the news and have raised prices. Downstream a little meng circle, thought this round of prices can fall below 3000 points, toward the 2 word, who knows suddenly bottomed out. The recent news of the new capacity of the glass plant is flying, and it is reasonable to assume that in the case of serious excess capacity, the price of glass fiber should rebound is tantamount to a pipe dream.

Requirements and advantages of composite photovoltaic border

Photovoltaic frame is an important part of solar photovoltaic modules, to package battery, glass, backplane and other materials, enhance the strength of the module, easy to transport, install and protect the role of photovoltaic modules, the product needs to have a strong carrying capacity and corrosion resistance.

Inventory of several common nondestructive testing methods for composite materials

As more and more composite materials and structures are used in various industries, understanding how to inspect them for damage is an important topic. This article will take stock of several common nondestructive testing methods for composite materials.

Polyurethane materials assist in the localization of high-speed rail core components

The CTCS onboard responder is installed at the bottom of the train, and the ground passive responder is installed on the railway line, serving as a signal transmission device on the line to send message information to the train. The CTCS onboard responder and ground passive responder are both composed of a casing, circuit board, and polyurethane filling. Polyurethane material has the function of protecting the circuit board and ensuring successful signal transmission.

Application of Composite Honeycomb Sandwich Structure in Civil Aircraft

Abstract: Composite honeycomb sandwich structures have the characteristics of high strength, high specific stiffness, low density, good compressive and bending resistance, and are widely used in the field of civil aircraft. The application areas include the fuselage, engine hood, fairing, cabin door, antenna hood, leading edge, etc. The widespread application of honeycomb sandwich structures has significantly reduced the weight of aircraft structures. With the advancement of molding technology and the improvement of material properties, honeycomb sandwich structures are gradually being applied to main load-bearing structures such as floors. This article first analyzes the research progress and development process of honeycomb sandwich structures. Secondly, the application of honeycomb sandwich structures on typical aircraft components was summarized. Finally, the current application status of honeycomb sandwich structures on civil aircraft floors was introduced.
