  玄武岩本是我国常见的一种普通铺路石料,但经过特殊手段处理后,它却能改变形态,变成一种泛着金属光泽的高性能纤维材料——玄武岩纤维。这种纤维的强韧度是钢材的5到10倍,重量却是同体积钢材的三分之一左右,相比之前,应用价值大大提升。因此,有人形象地把它的制造技术称为“点石成金术”。
 
  Basalt is a common paving stone in China,but after special treatment,it can change its shape and become a kind of high-performance fiber material with metallic luster--basalt fiber.The strength and toughness of this kind of fiber is 5 to 10 times of that of steel,but its weight is about one third of that of steel of the same volume.Compared with before,its application value is greatly improved.Therefore,some people vividly call its manufacturing technology"turning stone into gold".
 
  将玄武岩矿石粉碎磨粉后倒入熔炉,在超过1200摄氏度的高温加热下,粉料变成了液体状态。这些溶液经过澄清冷却和均质化后,通过漏板,在拉丝机的高速牵引下,像棉花糖一样被拉成一根根7至20微米的细丝,这就是玄武岩纤维。
 
  After the basalt ore is crushed and ground,it is poured into the furnace and heated at a high temperature of more than 1200℃,the powder becomes liquid state.After clarification,cooling and homogenization,these solutions are drawn into 7-20 micron filaments like marshmallow through the bushing plate under the high-speed traction of the wire drawing machine,which are basalt fibers.
 
  虽然一根玄武岩纤维丝的直径只有头发丝的三分之一,但其强度却是同等直径钢纤维的两倍,比合金耐腐蚀,能耐受500摄氏度的高温。加捻的玄武岩纤维像棉线,织成布可以用来做防护服。将玄武岩纤维和高分子基体采用特定的工艺成型后制得的纤维增强复合材料则具有高强度比,可以用来制造坦克、舰船、飞机的外壳。更可贵的是,玄武岩是一种天然矿石,制造玄武岩纤维的过程中基本没有有害物质排出,对环境污染很小。
 
  Although the diameter of a basalt fiber is only one-third of that of a hair,its strength is twice that of steel fiber with the same diameter.It is more resistant to corrosion than the alloy and can withstand high temperature of 500℃.Twisted basalt fiber is like cotton thread,woven into cloth can be used to make protective clothing.The fiber reinforced composites with basalt fiber and polymer matrix have high strength ratio,which can be used to manufacture the shells of tanks,ships and aircraft.What's more valuable is that basalt is a kind of natural ore,and there are no harmful substances discharged in the process of manufacturing basalt fiber,which causes little environmental pollution.
 
  玄武岩纤维的应用范围十分广泛,在航空、航天、建筑建材、道路桥梁建设、舰艇船舶制造、风力发电等领域都能大展身手。
 
  It can be widely used in the fields of building materials,building materials,building materials,building materials,building materials,building materials and so on.
