The impact of the accelerated development of rail transit on the lightweight fiberglass industry.

With the acceleration of urbanization in China, the demand for urban transportation has surged, and urban rail transit has entered a period of rapid development. The correct guidance of national policies and the active efforts of relevant cities in planning and constructing rail transit have shown a healthy and rapid upward trend in the development of urban rail transit in China in terms of speed, scale, and modernization level. The rapid rise of high-speed rail and urban rail transit has opened up new opportunities for non-metallic chemical materials, especially lightweight fiberglass materials. Urban rail transit in China is a systematic project that involves various fields of industry. Its scope covers locomotives, vehicles and components, rail transit transportation and management technology, infrastructure and electromechanical equipment, construction materials for urban rail transit, equipment, safety, energy-saving, environmental protection technology and maintenance, as well as planning, design, consulting, supervision services, engineering construction machinery and supporting equipment. Overall, it can be summarized into three major engineering categories: tunnel engineering, track engineering, and vehicle movement engineering. These three major projects have gathered domestic enterprises and attracted participation and cooperation from many well-known companies from Germany, France, Italy, Austria, Sweden, Switzerland, Belgium, Japan, Israel, the United States, Canada, South Korea, and other countries and regions. The speed of China's high-speed rail has reached 350 kilometers per hour, and the rapid operation of high-speed trains has made lightweight materials an important component. The three major lightweight materials are aluminum alloy, plastic, and fiberglass, with fiberglass becoming the main material for interior structural components. Currently, a modular series of products, passenger car seat series products, washroom series products, driver’s cab and driver’s compartment series products, sound insulation series products, and export products have been formed. Zhao Honghan, deputy secretary-general of the China Unsaturated Polyester Resin Industry Association, pointed out that to meet the high-quality performance requirements of supporting components for high-speed trains and light rail subways, China's fiberglass technology and products have been comprehensively improved in terms of raw material selection, structural design, and process molding. It is understood that there are more than 40 domestic fiberglass companies supporting the high-speed rail and light rail subway industries, forming a complete fiberglass industrial chain for rail transit. Zhao Honghan revealed that authoritative information obtained from relevant sources shows that the lightweight levels of boats differ significantly between domestic and international standards. "For example, in the case of lifeboats equipped with the same engine, the same type of boat built in China and Norway has different speeds; the lifeboat built in China can only reach a speed of 6 knots, while the one built in Norway can reach 11 knots." Using this example for comparison, it is clear that advancing the breadth and depth of lightweight rail transit in China still has a long way to go, and domestic fiberglass companies have great potential to seize the opportunities presented by the rapid development of rail transit.

The application of anti-corrosion fiberglass products in various fields.

Corrosion is ubiquitous, and the losses caused by corrosion each year are enormous: according to surveys from industrialized countries, the economic losses due to corrosion account for about 2-4% of their gross national product annually. In our country, the economic losses caused by corrosion amount to at least 200 billion yuan each year. Therefore, exploring new anti-corrosion measures and reducing losses caused by corrosion has always been a topic of effort for people. With the introduction of manufacturing equipment and technology for anti-corrosion fiberglass raw materials and products, the types and applications of anti-corrosion fiberglass products are becoming increasingly widespread in various sectors of the national economy. For different corrosive environments, selecting different resins to make fiberglass generally meets the anti-corrosion requirements, thus ensuring that fiberglass has a wide range of applicability in corrosion resistance. 1. Application of anti-corrosion fiberglass in the metal surface treatment industry: The acids used in metal surface treatment are mostly hydrochloric acid, and there are basically no issues using fiberglass. 2. Application of anti-corrosion fiberglass storage tanks in the high-purity water and food sectors: The excellent corrosion resistance of fiberglass means that this material has active and non-polluting characteristics, making it a suitable material for storing highly clean items such as high-purity water, pharmaceuticals, and milk. 3. Application of anti-corrosion fiberglass storage tanks and towers in the chlor-alkali industry: The chlor-alkali industry is one of the earliest application fields of fiberglass as a corrosion-resistant material, and fiberglass has now become a primary material in this industry. As early as the early 1950s, fiberglass was first used to collect hot (93°C) and humid chlorine gas, as well as organic substances from the mercury electrode. Subsequently, fiberglass was used to replace concrete electrolytic cell covers, solving the problem of concrete debris falling into the electrolytic cells after corrosion. Since then, fiberglass has gradually been used in various piping systems, gas blower mobility, heat exchanger shells, brine tanks, as well as in pumps, pools, floors, wall panels, grates, handles, railings, and other structural components. At the same time, fiberglass has also begun to enter various fields of the chemical industry. 4. Application of anti-corrosion fiberglass storage tanks and pipelines in the paper industry: The paper industry uses wood as raw material, and the papermaking process requires acids, salts, bleaching agents, etc., which have a strong corrosive effect on metals, while fiberglass materials can withstand harsh environments such as those with bactericides. 5. Extensive application of anti-corrosion fiberglass in the environmental protection industry: In the environmental protection industry, anti-corrosion fiberglass has been widely used in water supply and drainage pipeline projects. In recent years, the types of corrosive media and corrosion performance of wastewater have been continuously increasing, which requires the use of materials with better corrosion resistance, and anti-corrosion fiberglass is a good material to meet this demand. Applications of anti-corrosion fiberglass materials in environmental protection include general industrial waste gas treatment, oil-water treatment, and urban wastewater deodorization treatment. 6. Application of anti-corrosion fiberglass pipelines in seawater desalination: Since seawater easily corrodes iron materials, most of the pipelines and containers in desalination plants use fiberglass pipelines. 7. Application of anti-corrosion fiberglass storage tanks and pipelines in the pharmaceutical industry: There are many types of pharmaceuticals, each with its own raw materials, and fiberglass can well meet the anti-corrosion requirements in the pharmaceutical industry.
