将一粒沙变成一根纤维,再将这些纤维精密地编织在一起,做出空气过滤纸,通过2000倍的显微镜,可以看到一场微观世界的结构革命。 这些被称为玻璃纤维的新材料,超细又柔软,但却蕴含着巨大的能量。因为同时具备隔热隔音、水火不侵的功能,在科研人员的眼里,它们就 是中国现代工业领域的"混天绫"。 央视网消息:数据显示,2025年前5个月,重庆民营企业实现进出口1442.3亿元,占重庆外贸进出口总值的49.2%,撑起了重庆外贸经济的半壁 江山。其中,有一家民营企业正以其独特的创新活力与市场敏锐度,在新材料、新应用等工业化细分领域不断实现技术突破。 再升科技纤维研究院院长李志勇介绍,在飞机材料上有很多特殊的要求,比如要阻燃、防水、防潮,当然隔音和隔热是最基础的性能。这个火 焰温度能达到1200摄氏度,它会红但是不会烧成一个洞或者烧破。 攻克了核心技术,成为全球仅有的3家能够生产"飞机棉"的企业之一,也让中国成为继美国、日本之后,第三个掌握航空级超细纤维棉量产技 术的国家。 2021年,企业生产的第一批"飞机棉"正式交付并配套到首架C919上。从此,小纤维开始了大循环,美国企业也来下订单。 洁净空气 "飞机棉"的产业链再延伸 ...
