为获得多孔结构的建筑材料而采用铝粉进行发气的方法制作加气混凝土已在世界范围内得到推广。这样,国外正在生产特殊类型的铝粉发气剂。我国目前尚未生产专门用来制造多孔材料的铝粉,虽然仅多孔混凝土工厂每年就需要2千吨左右的ПАК—3号铝粉。生产后一种铝粉主要用于油漆涂料工业,因此要求它具有较高的涂敷能力,所以一般都在掺加硬脂的情况下研磨加工成铝粉,其粉状颗粒具有小
In order to obtain a porous structure of building materials, aluminum powder is used for gas generation to produce aerated concrete, which has been promoted worldwide. In this way, special types of aluminum powder gasifiers are being produced abroad. At present, China has not yet produced aluminum powder that is specially used for making porous materials, although only the porous concrete factory needs about 2,000 tons of ПАК-3 aluminum powder every year. After the production of a kind of aluminum powder is mainly used in the paint and coating industry, so it is required to have a higher coating capacity, so it is generally ground into aluminum powder with the addition of stearine, its powder particles have a small
