一、前言人们通常把矿物(角闪石或蛇纹石)纤维称之为石棉。它具有很多有用的技术性能(如耐热、耐磨、抗荷载下的变形、耐化学侵蚀、耐潮湿和抵制微生物等)。这些性能使石棉具有各种各样的技术用途。已经发现种类繁多、分布广泛的蛇纹石(温石棉)作为增强组分广泛用于石棉水泥(A/C)合复材料。A/C制品具有代表性的有板、瓦、管等。这些制品即使在表面无保护涂层的情况下,也能非常好地耐风化和耐腐蚀。尽管A/C制品具有某些独特的机械、物理和化学性能,但在某种环境下,破坏是众
I. INTRODUCTION People often refer to mineral (hornblende or serpentine) fibers as asbestos. It has many useful technical properties (such as heat resistance, abrasion resistance, deformation under load, chemical resistance, moisture resistance and resistance to microbes, etc.). These properties make asbestos have a variety of technical uses. It has been found that a wide variety of widely distributed serpentine (chrysotile) is widely used as an asbestos cement (A/C) composite material as a reinforcing component. A/C products are representative of plates, tiles, tubes, and the like. These products are very resistant to weathering and corrosion even in the absence of a protective coating on the surface. Although A/C products have some unique mechanical, physical, and chemical properties, under certain circumstances, damage is common.
