Human production and living activities require a large amount of energy as support, and the scarcity of traditional energy and conflicts in important global energy sources have further exacerbated the energy crisis. In addition to developing new energy, human beings also need to further reduce energy consumption. Compared with metal materials, glass FRP products The superior performance is its adv...

On July 4, 2023, the World Meteorological Organization announced the formation of El Nino conditions in the tropical Pacific Ocean for the first time in seven years, and the organization's Secretary-General, Petrie Taras, pointed out that the appearance of El Nino will greatly increase the possibility of temperature records being broken, which may cause extreme heat in many parts of the world.
El Nino is a tropical ocean anomaly characterized by significant warming in the eastern and central equatorial Pacific Ocean. El Nino usually causes a variety of abnormal changes such as high temperature, drought and fire, heavy rainfall, and high incidence of super typhoons. For example, the number of storms and typhoons in the Pacific region usually increases, and these storms and typhoons may cause floods, landslides and other disasters, thus posing a threat to people's life and property safety, and bringing a huge impact on human life, production and business activities. Among these climate anomalies, the most prominent impact is the emergence and continuous spread of global hot weather.

The latest report released by the World Meteorological Organization pointed out that extreme high temperatures continue to affect the world, the global average temperature in June set a record high record, and the record high temperature weather continues to appear in July, the temperature in many parts of Europe has exceeded 40 degrees Celsius, Asia and North America are also receiving extreme high temperature "baking" test.
The National Weather Service said that on July 18, more than 20 cities, counties or regions in the United States had tied or broken daily high temperature records, and it began to extend to the central and eastern United States. At the same time, many European countries, including Italy and Spain, have issued red alerts for high temperatures. Meteo France is forecasting temperatures of up to 40 degrees Celsius in parts of southeastern France this summer. The felt temperature in many parts of Thailand reached a staggering 54 degrees Celsius. According to the monitoring data of the National Meteorological Center, since June this year (as of June 22), the daily maximum temperature of 183 national meteorological stations in the country has exceeded the monthly extreme value, and the temperature detected by 46 meteorological stations has exceeded the historical extreme value, and the number of hot days in North China has reached 6.4 days, 3.1 days more than the same period in previous years.

The appearance of extreme high temperature not only makes rivers and lakes dry up, abnormal rainfall causes a certain degree of production reduction of main grains, fruits and vegetables and other crops, the large-scale melting of sea glaciers in the north and south poles causes sea level rise, flooding low-lying areas, extreme typhoons and storms on the coastlines of coastal areas, buildings caused by washing, and even the normal operation of the power system caused a huge burden.
In the face of the periodic El Nino phenomenon, especially in the face of the resulting multi-layered impact on human life, production and business activities, all mankind, on the basis of the principle of "emphasizing both mitigation and adaptation", should actively adhere to the implementation of the United Nations Framework Convention on Climate Change, actively fulfill the principal responsibilities of all parties, and strengthen global cooperation. Actively promote the goal of "carbon peak, carbon neutral", vigorously promote the development and consumption of renewable energy such as photovoltaic, actively explore the use of new steel bars, doors and Windows, curtain wall systems to build "energy-saving buildings" in urban buildings, and vigorously promote light, high strength, low energy consumption, corrosion resistant guardrail & cable tray system in industry and petrochemical industry. New slope protection systems are used in areas prone to landslides and landslides such as rivers, lakes and coastal areas, and seawater corrosion-resistant "GRP/FRP pipes and FRP bolts" are used in seawater intake of seawater desalination facilities.
Nanjing Sedray Industries Co., Ltd. , as a company with social responsibility, in the face of the common natural enemy of mankind "El Nino", we have specially developed FRP products series——Dragonbolt™ Composite Fasteners、Dragonbar™ FRP Reinforced System, Dragonpro™ Fiberglass Building Products (including：(1) standard structural profiles, (2) FRP handrail systems, (3) FRP decks & floors, (4) FRP gratings and accessories), Dragonstrut™ Fiberglass Framing System (fiberglass support system) , Dragonpower™ Cable Management System .These products mainly use high performance reinforced glass fiber and corrosion resistant resin and necessary additives, through the pultrusion process and special processing technology to produce, compared with traditional materials (steel, aluminum, stainless steel, plastic), has a very obvious advantage:
1. Low thermal expansion coefficient: the thermal conductivity of FRP products is 0.487 W /(M.K), only 1/100 of metal, specially suitable for outdoor construction, long-term high temperature will not cause skin burns;
2. Corrosion Resistance: FRP/GFRP products will never corrode, rust or lead to concrete spalling in the concrete structure;
3. High Chemical Resistance: wastewater treatment, water treatment and desalination plants exposed to chemicals, water or high salt content of the environment, FRP/GFRP products can be very good resistance to the corrosion of the harsh environment;
4. Long Life Cycle: FRP/GFRP products are very durable, therefore, can reduce later maintenance and upgrade costs;
5. Light Weight and High Strength: The density of FRP reinforcement products is only 1/4 of that of metal materials. In modern times with high labor costs and oil prices, labor costs and transportation costs can be greatly reduced. At the same time, the frp rock bolts has strong thread load capacity, which can effectively substitute the use of metal rock bolts (slope support bolts);
6. Low Moisture Absorption: unlike many plastics, the moisture absorption of FRP products is very low, even if it is soaked in water for a long time, there will be no obvious size change or mechanical property loss.
