阅读说明：本技术 无结晶二氧化硅的低生物持久性无机纤维 (Low biopersistence inorganic fibers free of crystalline silica ) 是由 D.赵 B.K.佐伊托斯 M.J.安德烈卡克 J.M.哈米尔顿 K.L.汉森 于 2018-10-05 设计创作，主要内容包括：一种无机纤维,其含有二氧化硅、氧化铝、一种或多种碱金属氧化物和一种或多种碱土金属氧化物、过渡金属氧化物或镧系金属氧化物。无机纤维在1260℃以上的使用温度下表现出良好的热性能,在暴露于使用温度后保持机械完整性,在失透后不含结晶二氧化硅,耐碱性熔剂,在酸性介质中表现出低的生物持久性,而在中性介质中表现出低的溶解度。还提供了掺入有无机纤维的隔热产品、制备无机纤维的方法和使用从无机纤维制备的隔热体来使制品隔热的方法。(An inorganic fiber comprising silica, alumina, one or more alkali metal oxides and one or more alkaline earth metal oxides, transition metal oxides or lanthanide series metal oxides. Inorganic fibers exhibit good thermal properties at service temperatures above 1260 ℃, maintain mechanical integrity after exposure to service temperatures, are free of crystalline silica after devitrification, are resistant to alkaline solvents, exhibit low biopersistence in acidic media, and exhibit low solubility in neutral media. Also provided are insulation products incorporating inorganic fibers, methods of making inorganic fibers, and methods of insulating articles using insulation made from inorganic fibers.)
