要解决因建筑装饰工程材料而引起的火灾问题,关键是要解决防火性能,即不燃性,其次是物理性能。针对这一问题,人们开始寻求新型的装璜材料。因此,一种以改性特种水泥为基材的各种防火材料相继问世。目前这种材料还处于萌芽阶段,质量参差不齐,特别是目前市上出现的许多种防火件,普遍存在返卤问题,一遇阴雨天,材料表面就出现潮湿现象,有的表面还出现水珠。因此,产品若不克服返卤问题是难以推广使用的。
To solve the fire problem caused by building decoration engineering materials, the key is to solve the fire performance, that is non-flammability, followed by physical properties. In response to this problem, people began to seek new types of mounting materials. Therefore, a variety of fire-retardant materials based on modified special cements have come out one after another. At present, this kind of material is still in its infancy, and the quality is uneven. In particular, many types of fire prevention parts that are present in the city currently have the problem of returning halogen. In the event of a rainy day, moisture appears on the surface of the material, and water appears on some surfaces. Beads. Therefore, if the product does not overcome the problem of returning halogen, it is difficult to promote the use.
