石棉瓦的危害
石棉瓦的危害
The harm of asbestos tile
石棉瓦是一种天然的矿物 , 根据其生成不同可分为纤维蛇纹石石栋和角闪石石棉两大类.我们最常见到的是纤维蛇纹石石棉 , 因而这一种石棉用处最大。 这种石棉也称为温石棉。 温石棉是含有结晶水的镁硅酸盐 。 由于温石棉具有 良好 的耐火、 耐碱、 坑拉强度高 , 容重小以 及很好的吸 附能力等优点 , 因而石棉能与水泥很好地结合在一起。 我们常见的一些简易屋顶就是用波形石棉水泥瓦搭建的, 此外工厂为 了 防火方面的考虑不少车间里 也用石 棉瓦。
Asbestos is a natural mineral. According to its formation, it can be divided into two categories: fibrous serpentine stone and hornblende asbestos. The most common one is serpentine asbestos, which is the largest asbestos. This asbestos is also known as chrysotile asbestos. Chrysotile is a magnesium silicate containing crystalline water. Asbestos can be well combined with cement because of its advantages of good fire resistance, alkali resistance, high tensile strength, small bulk density and good adsorption capacity. Some of our simple roofs are made of corrugated asbestos cement tiles, and many factories also use asbestos tiles for fireproofing.
石棉瓦中温石棉约占15 一 20 % ,普通硅 酸盐水泥占8 0 一85 % , 它们能牢固的结合,因而不含有石棉粉尘飞扬 和对人体的危害。而石 棉对人的危害主要是指石 棉采矿、 运输、生产过程中产生的石棉粉尘飞 扬而造成的。 如汽车刹车片, 山于 摩擦而产生的粉尘对环境会造成一定的影响,当然也会危害人的健康。 [2]
Asbestos is about 15 to 20% asbestos, and 80 to 85% of ordinary portland cement. They can combine firmly, so it does not contain asbestos dust flying and harm to the human body. Asbestos is harmful to human beings mainly because of asbestos dust produced during the process of asbestos mining, transportation and production. Such as automobile brake pad, the dust produced by friction on the mountain will have a certain impact on the environment, of course, it will also endanger human health. [2]
这是一种国际上公认的淘汰建筑材料。其危害来自于它的纤维，这是一种非常细小，肉眼几乎看不见的纤维，当这些细小的纤维释放以后可长时间浮游于空气中，被吸入人体内，被吸入的石棉纤维可多年积聚在人身体内，附着并沉积在肺部，造成肺部疾病。
This is an internationally recognized building material eliminated. The harm comes from its fiber, a very small, almost invisible fiber. When these tiny fibers are released for a long time to float in the air, inhaled asbestos can accumulate in the human body for many years, attached and deposited in the lungs to cause lung disease.
