松散性防水是区别于刚性防水、柔性(卷材和涂料)防水的一种新体系的建筑防水技术,它独树一格于国内、国际的建筑防水科技领域。松散性防水是以单一的具有憎水性的建筑拒水粉平铺于平屋面基层所构成的防水层。经测试,在基层上如有3毫米厚度的拒水粉的粉层,即能承受1米高的水压;且化学性能稳定,耐热、抗冻、耐老化,可与建筑物寿命共存。这种建筑拒水粉是以脂肪酸钙为主体,通过特定结构形式组成的复合型粉状物质,呈白色、无具、无毒、无放射性危害。其技术性能见表1。由建筑
Loose waterproofing is a new type of building waterproof technology that is different from rigid waterproof, flexible (coil and paint) waterproof, and it is unique in domestic and international architectural waterproofing technology. Loose waterproofing is a waterproof layer consisting of a single, water-repellent building water repellent powder tiled on the base layer of a flat roof. After testing, if there is a powder layer of water-repellent powder with a thickness of 3 mm on the grass-roots level, it can withstand a water pressure of 1 meter; and it has stable chemical properties, heat resistance, frost resistance, and aging resistance, and can coexist with the life of buildings. This type of building water-repellent powder is a complex powdery substance composed mainly of fatty acid calcium and has a specific structure. It is white, non-toxic, non-toxic and non-radioactive. Its technical performance is shown in Table 1. By the building
