Noncrystalline biodegradable heat resistant inorganic fibres comprising Si02, CaO and P205 |
| 摘要 |
<p>Calcium silicate noncrystalline organic fibers containing a sufficient amount of CaO for making the KI value at least 40 and added with from 0.5 to 7% by weight of P2O5 for improving the heat resistance. The noncrystalline organic fibers have the carcinogenic index, KI value of at least 40, have a low accumulating property in the human body, and have a high heat resistance over the level of conventional rock wools. <IMAGE></p> |
