By 2025, extreme climate events will further ravage the Earth. Extreme heat zones will expand, Greenland's 3 million-year-old ice will melt, and China's high-temperature and rain belts will shift northward. Wildfires, droughts and floods will continue, and food production will decline. These disasters, compounded by the "heat dome" phenomenon, will unfold, further necessitating urgent ac...

The petrochemical industry is an important pillar industry of the national economy. With the continuous rise of international oil prices and the continuous advancement of the goal of "carbon neutrality" in 2035, it is becoming more and more urgent for our country to accelerate the implementation of the "refining and chemical integration process". FRP building products and FRP c...

In the 21st century, human's demand and consumption of natural resources has entered a new stage, and the demand for steel bars in infrastructure construction is also increasing. In 2020, the apparent consumption of global iron ore production is 23.157 million tons, which leads to the need for more iron ore excavation and coal burning. These production activities are bound to cause serious damage to the natural environment, and although we have taken more environmentally friendly production process as far as possible in the production of steel, but also can not completely eliminate the impact of waste gas and heat on the natural environment.
Especially in the past decade, extreme climate represented by "El Nino-La Nina" has become increasingly frequent. Natural disasters such as high temperature, strong wind, heavy rain, flash floods and mountain fires have emerged in an endless stream, causing increasingly serious and frequent damage to human infrastructure and causing incalculable losses. With the aging of human society and the further deepening of social division of labor, labor shortage and labor cost are also rising. Especially in the past two years, due to the outbreak of COVID-19, the production capacity and transport capacity have decreased significantly, the prices of bulk commodities, especially iron ore and coal, have been constantly rising, leading to the price of steel bars, and the comprehensive construction cost of infrastructure has been constantly rising under the influence of various factors. For future infrastructure construction, we urgently need a new kind of "rebar "!
At this year's two sessions, carbon peaked and carbon neutral were written into the government work report for the first time. In September 2020, China announced to the world that it would strive to achieve a carbon peak by 2030 and carbon neutrality by 2060. Achieving carbon peaking and carbon neutrality is not only a national strategy, but also the responsibility of all sectors of society.
As the main participants of market economic activities, enterprises assume the function of providing products and services to the society, and play an important role and responsibility in promoting the process of social green and low-carbon transformation and development.
Dragonbar™ Fiberglass rebar (FRP Rebar) is manufactured by Nanjing Sedrui Industries Co., LTD using the pultrusion process and the latest processing technology. Their mechanical properties and bonding properties are superior to those of steel bars, and they maintain good mechanical properties in a corrosive environment, with a design life of up to 100 years. Its main content materials are reinforced glass fiber materials and high performance resin. Therefore, compared with the traditional steel reinforcement material, the steel reinforcement material shows obvious excellent properties: flame retardant, corrosion resistance, non-conductive, low thermal conductivity, low thermal expansion coefficient, non-magnetic, light weight, high strength, low maintenance. Applications include: barrier walls, roads, Bridges and tunnels, electrical isolation, oceans and structures, spillway channels, water treatment plants, nuclear magnetic resonance chambers, etc.
