Inorganic ceramic fiber capable of being dissolved in human body fluid and its production method

A human body fluid soluble inorganic ceramic fiber and method for making same, the composition by weigh percent of the fiber is, SiO2 50-85%, CaO 5.5-35%, MgO 1-10%, B2O3 1-2%, Al2O3 0-1%, Fe2O3 0-0.5%, Na2O 0-0.5%, K2O 0-0.5%. The preparation process comprises melting the materials at 1500-2000 deg. C, subjecting the melted liquid to 0.3-0.6 MPa high-pressure blast blowing, and collecting floss. The fiber can be quickly degraded in human body liquid, thus minimizing the harm of inorganic ceramic fiber to human body. 一种可溶于人体体液的无机硅酸盐纤维及其制造方法。该纤维的重量百分组成为：SiO#-[2]50～85％；CaO 5.5～35％；MgO 1～10％；B#-[2]O#-[3] 1～2％；Al#-[2]O#-[3] 0～1％；Fe#-[2]O#-[3] 0～0.5％；Na#-[2]O0～0.5％；K#-[2]O 0～0.5％。诸料在1500～2000℃熔融；熔融液经过0.3～0.6MPa高压风喷吹或甩丝，经集棉制得。其物理性能指标是：直径1～10μm；长度30～250mm；渣球含量5～15％；溶解度100～250mg/L。该纤维在人体液中有足够的溶解度、可快速降解，缩短了无机硅酸盐纤维在人体内的停留时间。将无机硅酸盐纤维对人体的损害降至最低。
