Owens Corning composites can avoid huge losses caused by corrosion
Owens Corning (nyse:oc), the world's leading enterprise in glass fiber reinforced composites, residential and commercial building materials, will hold a technical seminar during the China Composites Expo. The symposium will focus on how developing countries can use today's advanced materials and processes such as corrosion-resistant glass fiber reinforced polymer composites to avoid huge losses caused by corrosion, which makes a lot of money spent on infrastructure maintenance and replacement every year
just take China as an example. If the current construction and material selection methods are continued, it is estimated that in 17 years, when China becomes the world's largest economy, the annual losses caused by corrosion will exceed US $1trillion (6.8 trillion yuan). If anti-corrosion optimization measures are adopted, China can save as much as 347billion US dollars per year, but although plastic film can be converted into RMB (2.4 trillion yuan)
the latest statistics on the content of packaging material distributors officially replaced the previous "packaging tax" on January 1, 2013. It shows that the direct cost of corrosion worldwide is estimated to have exceeded US $1.8 trillion (about 12.2 trillion yuan), accounting for 3% to 4% of gross national product (GDP) in industrialized countries. (2) After many infrastructures were corroded after installation, developed countries have developed new material solutions. If appropriate anti-corrosion measures are adopted, it is estimated that the loss caused by corrosion can be reduced by 25% to 30% every year. (3)
calculated according to the proportion of the direct cost paid by industrialized countries for corrosion accounting for 4% of their GDP, and according to the estimation that the loss can be reduced by 30% by adopting appropriate anti-corrosion measures every year, in 2027, other developing countries with rapid economic growth are expected to save huge amounts of money every year, which can be as high as $54billion in Brazil, $54.6 billion in Russia and $130.2 billion in India
Xu Jingji, head of Greater China marketing of Owens Corning reinforcement business unit, said: "developing countries can now avoid repeating the mistakes of industrialized countries and falling into a costly maintenance and replacement cycle by using advanced materials such as composite materials and manufacturing processes. You know, in the past, when many developed countries built their core infrastructure, these materials and methods have not yet appeared."
Xu Jingji also added: "fiber reinforced composite (FRP) has more than 50 years of field use history, and it has become a reliable technology. For example, the service life of chemical storage tanks and pipelines made of corrosion-resistant composite materials has always been longer than those made of metal. The service life of composite materials has reached more than 50 years, and they are still in use, and there are many examples in this regard."
even under extremely corrosive conditions, today's composites have the potential to surpass those early applications. For example, compared with standard E glass, Advantex boron free and fluorine-free glass has more excellent composite properties when facing corrosive environment
Xu Jingji concluded, "the actual growth rate of China's infrastructure industry in 2010 is expected to be 25%, with a total of US $168.5 billion (equivalent to 1 trillion yuan). We hope to ensure that a large part of these funds are used for corrosion-resistant composite materials, so that China can avoid or even use them between different materials, and pay a high price for infrastructure maintenance and replacement in the future."
corrosion is a natural process that occurs because materials (such as refined metals) are easily oxidized to more stable compounds. If there is enough time, oxygen and water, all ironware will eventually be completely converted into rust and decomposed. Corrosion depends on the nature of the soil and other environmental factors, such as exposure to moisture and oxygen, high conductivity, high acidity and salt
