综合能耗降低，干燥效果提升！这款气凝胶干燥仪了解下？

Core Viewpoint - The article discusses the advancements and applications of supercritical drying technology in the production of aerogels, highlighting its maturity and prevalence in the industry, particularly in China [2][3]. Group 1: Supercritical Drying Technology - Supercritical drying technology is the earliest and most mature method for bulk production of aerogels, commonly using carbon dioxide as the drying medium [2]. - The core equipment for this technology is a high-pressure vessel, typically operating at pressures of 7 to 20 MPa, which is complex and has high operational and maintenance costs [2]. - There is no significant difference in product performance between silica aerogels produced by supercritical drying and atmospheric drying, as both can meet technical specifications [2]. - Supercritical drying technology is more mature for non-silica aerogel production, and its efficiency, safety, and process adaptability are highly dependent on the reliability of the equipment system [2]. - New entrants in the aerogel industry often choose supercritical processes due to lower technical barriers when reliable equipment is provided, despite the higher investment costs associated with atmospheric drying technology [2]. Group 2: Company Focus - Shijianjia Technology specializes in the development and application of supercritical fluid technology, focusing on supercritical drying and extraction equipment [3]. - The company's supercritical dryer is designed specifically for aerogel drying, featuring an integrated design that occupies less space and operates fully automatically, with precise control over pressure and flow rates [3]. - The dryer is utilized by several renowned aerogel research institutions in China, including the Suzhou Institute of Nano-Tech and Nano-Bionics, Tsinghua University, and Xi'an Jiaotong University [3]. Group 3: Upcoming Events - The Fourth Advanced Gel Materials and Industrial Applications Forum will be held from October 21-23 in Suzhou, where Shijianjia Technology will showcase its new product, the fully automatic supercritical dryer SCD-380A [6]. - The SCD-380A features a 10-inch touchscreen for operation, automated control of the drying process, and can handle various samples, including MOFs, gels, biological samples, and wafers [6].
