很早以来云母(尤其是云母鳞片)就在建筑材料中得到应用。最近甚至在制砖工业中也使用了相当数量的绢云母,此外还利用云母鳞片振动衰减特性来研制钢板喷涂材料,在外部建筑材料中也得到了应用。国外认为云母鳞片的覆盖性、尺寸稳定性是有利条件,若将云母与塑料等基体配合使用,能制成将来有发展前途的外部建筑材料,目前正在讨论云母与聚乙烯配合使用的问题,现将国外目前云母的应用情况作一简单的介绍。
Mica (especially mica flakes) has long been used in building materials. Recently, even a considerable amount of sericite has been used in the brick making industry. In addition, the steel plate spraying material has been developed by utilizing the vibration attenuation characteristics of mica flakes, and has also been applied in external building materials. Foreign countries believe that the coverage and dimensional stability of mica flakes are favorable conditions. If mica is used in combination with plastics and other substrates, external building materials with promising future will be made available. Currently, the issue of the use of mica and polyethylene in combination is being discussed. The current application of mica in foreign countries is briefly described.
