列入浙江省科委新产品开发计划项目的硅酸铝纤维—离心玻璃棉复合制品,最近在浙江省杭州市通过了鉴定。众所周知,普通硅酸铝纤维保温材料的长期使用温度可以达到850～900℃,但它与离心璃棉等超轻质保温材料相比,具有体积密度大、导 The aluminum silicate fiber-centrifugal glass wool composite products listed in the New Product Development Project of the Zhejiang Provincial Science and Technology Commission have recently passed the appraisal in Hangzhou City, Zhejiang Province. As we all know, the long-term use temperature of ordinary aluminum silicate fiber insulation material can reach 850 ~ 900 °C, but compared with ultra-lightweight insulation material such as centrifugal glass wool, it has a large bulk density, guide
