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...

Entering the post-epidemic era, global competition among enterprises continues to intensify and product homogenization becomes more serious. Enterprises are inevitably urged to continue to promote their "branding" process! The improvement of the "trademark brand matrix" is one of the core steps in this critical process!

The intensification of business globalization competition and the proliferation of commodity homogeneity inevitably require enterprises to accelerate their "branding" process! The completion of "trademark registration" is one of the key steps in this process!

The continuous and repeated outbreak of the Covid-19 epidemic in the world for more than two years, coupled with the outbreak and continued intensification of the conflict between Russia and Ukraine at the end of February 2022, has led to a sharp rise in global commodity prices, especially steel, steel bars, electrical materials, etc. It greatly weakens the profitability of downstream enterprises ...

Entering the 21st century, with the intensification of human production and living activities, the adverse impact on the climate and environment has become greater and greater, resulting in an increasing frequency of extreme climates. Endangering the safety and service life of global infrastructure, causing immeasurable loss of life and property.
According to the "2021 State of the Global Climate Report (January-September)" released by the World Meteorological Organization at the 26th United Nations Climate Change Conference, the global average temperature (January-September) in 2021 will be higher than that of 1850-1900 At about 1.09 degrees Celsius, it is currently ranked by the World Meteorological Organization as the sixth or seventh warmest year on record globally. Data show that global greenhouse gas concentrations have reached new highs in 2020, and this increase will continue in 2021. At the same time, due to global warming, the ocean is first facing a serious warming problem. At present, the temperature of the water at a depth of 2,000 meters in the upper ocean has reached a new record. Simultaneously, the oceans are being acidified by rising concentrations of the greenhouse gas, absorbing about 23% of the carbon dioxide that humans emit each year. It also reduces the ability of the oceans to absorb carbon dioxide, further exacerbating the problem of atmospheric greenhouse gas concentrations.

The worsening climate situation has further led to frequent occurrence of extreme weather worldwide.
From an international perspective, blizzard and low-temperature weather in early 2021 will affect the United States, especially the southwestern state of Texas. Many people died and millions of homes and businesses were without power. In March, the eastern coast of Australia continued to rain, and New South Wales suffered a 50-year flood that washed away a lot of infrastructure. In July, extreme rainfall also hit many countries in Western Europe, triggering floods and causing heavy casualties and property damage.
From a domestic perspective, data from the National Climate Center show that from May 1 to June 15, 2022, the average precipitation in Fujian, Guangdong, and Guangxi provinces reached 621 mm, which is the highest in history since 1961. Warnings have been issued in many places. The risk level of heavy rain and mountain torrent remains high, and the resulting mudslides and landslides have caused serious damage to the supporting facilities such as electric power, water conservancy and buildings in many mountainous areas and expressways, and greatly affected the effective smooth flow of roads, tunnels and railways in the disaster-stricken areas. , which has further impacted the "industrial supply chain" that has been hit hard under the influence of the epidemic, which is not conducive to the stable and healthy development of the national economy. Meanwhile, the product characteristics of traditional metal materials and building materials also determine that the reconstruction of infrastructure in post-disaster areas, especially in mountainous areas, poses huge challenges in terms of manpower and material resources.
Dragonbar™ FRP Reinforcement system developed by Nanjing Sedray Industries Co., Ltd. to give full play to the superior characteristics of fiber reinforced materials in the increasingly complex and changeable climate environment including：(1) Dragonbar™ FRP Rebar, (2) Dragontie™ FRP Formwork Tie Rod, (3) Dragonanchor™ GRP Solid Rock Bolt, (4) Dragongrip™ GRP Hollow Grouting Bolt, (5) Dragongrip™ GRP Self-drilling Hollow Anchor , mainly made of high-performance reinforced glassfiber and corrosion-resistant resin and necessary additives through pultrusion molding process and special processing technology. Compared with traditional materials (steel, aluminum, stainless steel, plastic), it has obvious advantages:
1, Corrosion Resistance: FRP reinforcement products will never corrode, rust or lead to concrete spalling in the concrete structure;
2, 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);
3, Long Life Cycle: FRP reinforcement products are very durable, therefore, can reduce later maintenance and upgrade costs;
4. Non-magnetic interference: FRP reinforced products will not produce magnetic interference, especially for non-magnetic buildings involved in mountainous areas (such as earthquake monitoring stations, highway ETC toll stations);
5, Low Moisture Absorption: unlike many plastics, the moisture absorption of FRP reinforcement 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.
