上海科学家研发防水耐火纸 有助纸质文物保存(在线收听) |
In January 2015, a fire in one of Russia's largest university libraries damaged more than 1 million historical documents, an incident which some media described as a "cultural Chernobyl". 2015年1月,俄罗斯最大的大学图书馆之一发生了火灾,损坏了100多万本历史文献,一些媒体将这一事件描述为“文化切尔诺贝利”。
Important documents of our age can probably avoid the same fate in the future thanks to a new fire-resistant paper developed by a team of scientists at the Shanghai Institute of Ceramics affiliated to the Chinese Academy of Sciences.
我们这个时代的重要文献在将来可能能够避免同样的命运,因为中科院上海陶瓷研究所一队科学家发明了一种新型耐火纸。
Zhu Yingjie, a researcher from the institute, and his team developed a set of methods to produce paper with a new material, hydroxyapatite, the inorganic constituent of tooth enamel and bone.
该研究所的研究员朱英杰和其团队成功研发出了一套方法,用一种名叫羟基磷灰石的新材料来造纸,羟基磷灰石是牙釉质和骨的无机成分。

The inorganic material is both fire resistant and water resistant.
这种无机材料既耐火又防水。
"Traditionally, paper is made of plant fibers, which are easily destroyed by liquid. Previous research attempts to produce waterproof paper found it was difficult to achieve fire retardancy and water repellency at the same time," Zhu said.
朱英杰说道:“传统上,纸是由植物纤维制成的,很容易被液体破坏。在以往试图研究制造防水纸的过程中,人们发现很难同时实现防水和耐火。”
In 2013, a doctorate student of Zhu was preparing hydroxyapatite nanowires. While he wanted to filter out the water and continue the experiment, he found that instead of getting hydroxyapatite powder on the filter paper, a film formed on the paper.
2013年,朱英杰一名博士学生在准备羟基磷灰石奈米线。当他想过滤掉水继续试验的时候,他发现留在过滤纸上的不是羟基磷灰石粉末,而是形成了一张薄膜。
The discovery inspired Zhu. He conducted more experiments to improve the material's physical properties.
这一发现启发了朱英杰。他进行了更多的实验来改善这一材料的物理性能。
"Traditional papermaking damages natural woods and damages the environment. Hydroxyapatite nanowires are an ideal building material for paper," Zhu said.
朱英杰说道:“传统造纸方法会损害天然木材、破坏自然环境。羟基磷灰石奈米线是一种理想的造纸材料。” |
