The strengths decrease in order crocidolite chrysotile, amosite. 强度按青石棉,温石棉,铁石棉顺序下降。
A method of identification for low content chrysotile, crocidolite and amosite in brake rubber of bicycle by the united way of polarized light microscope and X-ray diffraction had been established. 本文提出了采用偏光显微镜和X射线衍射仪联合方法鉴定自行车闸皮中低含量的温石棉、铁石棉及青石棉等三种石棉的方法。
The variation of ultimate tensile strength with length for amosite crocidolite, chrysotile is shown in Table 2.10. 铁石棉,青石棉和温石棉的极限抗拉强度随长度的变化情况见表2.10。
Conclusion Amosite granular dust has the effects of causing carcinoma. 结论颗粒状铁石棉粉尘具有致癌作用。
