耐辐照玻璃纤维以及利用其制成的针刺毡
摘要：
本发明涉及一种耐辐照玻璃纤维，由如下原料制成：SiO2：50～60％，Al2O3：18～25％，MgO：10～15％，CaO：3～15％，BaO：0～3.5％，不可避免的杂质为0～0.9％，所述百分比为质量百分比。采用本发明原料，可用现有耐火材料构造的熔窑、拉丝炉进行熔制和拉丝生产耐辐照玻璃纤维，纤维经过短切、分梳、铺网和针刺工艺，形成具有特定密度的针刺毡制品，具备良好的可生产性，适应工业的连续化生产。生产出的耐辐照玻璃纤维针刺毡可作为核辐照环境下的保温隔热材料，具有耐高温、轻质柔软、易安装等特性。
摘要（英）：

The invention relates to a radiation-resistant glass fiber which is prepared from the following raw materials in percentage by mass: 50-60% of SiO2, 18-25% of Al2O3, 10-15% of MgO, 3-15% of CaO, 0-3.5% of BaO and 0-0.9% of inevitable impurities. The raw materials can be subjected to melting and wire drawing by using the existing melting furnace and wire drawing furnace made of refractory materials so as to produce the radiation-resistant glass fiber. The fiber is subjected to chopping, dehairing, mesh placement and needling to form the needled felt product with specific density. The needled felt product has favorable producibility and is suitable for industrial continuous production. The radiation-resistant glass fiber needled felt can be used as a heat insulating material in a nuclear radiation envelopment, and has the characteristics of high temperature resistance, light weight, high flexibility, high installability and the like.
