为建筑穿上绿色节能“新衣”

Core Viewpoint - The development of a new type of aerogel-based insulation film by China Railway Construction Corporation (CRCC) aims to enhance energy efficiency in buildings while maintaining natural light and comfort for residents [1][2]. Group 1: Product Development - The aerogel insulation film has achieved stable mass production capabilities of over 110 tons [1]. - The film is only 50 micrometers thick, which is about half the thickness of a standard A4 paper, and features a complex structure that provides high insulation, UV protection, and light transmittance [1][2]. - The infrared blocking rate of the film is 94.3%, and it has a UV transmittance of only 0.2%, making it highly effective for energy-saving applications [2]. Group 2: Market Potential - Aerogel materials have a porosity exceeding 90% and are recognized as the "king of insulation" in materials science, with potential applications in energy-efficient buildings and urban renewal [2]. - The company has developed three products targeting the construction market: aerogel powder, insulation coatings, and the aerogel insulation film, supported by multiple invention patents [2][3]. Group 3: Production Process - The production process has transitioned to a low-cost, pressure-reduced method, allowing for a daily stable output of 1 ton of aerogel material [3]. - The team has successfully implemented aerogel materials in practical applications, such as reducing indoor temperatures by approximately 5 degrees Celsius in renovated buildings [3][4]. Group 4: Future Plans - The company plans to expand its aerogel material pilot production and establish technical standards for related products, aiming to lower production costs and promote energy-efficient building solutions [4].
