1、耐水性:耐水性是指在水的作用下和被水浸润后其性能基本不变,在压力水作用下具有不透水性 ,常用不透水性、吸水性等指标表示。
1. Water resistance: water resistance refers to that its performance is basically unchanged under the action of water and after being soaked by water. It is impermeable under the action of pressure water. It is commonly expressed by impermeability, water absorption and other indicators.
2、温度稳定性:温度稳定性指在高温下不流淌、不起泡、不滑动,低温下不脆裂的性能,即在一定 温度变化下保持原有性能的能力。常用耐热度、耐热性等指标表示。
2. Temperature stability: temperature stability refers to the performance of no flowing, no foaming, no sliding at high temperature and no embrittlement at low temperature, that is, the ability to maintain the original performance under certain temperature changes. It is commonly expressed by heat resistance, heat resistance and other indicators.
3、机械强度、延伸性和抗断裂性:它指防水卷材承受一定荷载、应力或在一定变形的条件下不断裂 的性能。常用拉力、拉伸强度和断裂伸长率等指标表示。
3. Mechanical strength, extensibility and fracture resistance: it refers to the performance that the waterproof coiled material will not break under certain load, stress or deformation. It is commonly expressed by indexes such as tensile force, tensile strength and elongation at break.
4、柔韧性:柔韧性指在低温条件下保持柔韧性的性能。它对保证易于施工、不脆裂十分重要。常用 柔度、低温弯折性等指标表示。
4. Flexibility: flexibility refers to the ability to maintain flexibility under low temperature conditions. It is very important to ensure easy construction and no embrittlement. It is commonly expressed by flexibility, low-temperature bending and other indicators.
5、大气稳定性:大气稳定性指在阳光、热、臭氧及其他化学侵蚀防水材料,防水材料品牌,防水卷 材性能介质等因素的长期综合作用下抵抗侵蚀的能力。常用耐老化性、热老化保持率的等指标表示 。
5. Atmospheric stability: atmospheric stability refers to the ability to resist erosion under the long-term comprehensive action of factors such as sunlight, heat, ozone and other chemical erosion waterproof materials, brand of waterproof materials, performance of waterproof coiled materials, media and so on. It is commonly expressed by aging resistance, heat aging retention rate and other indicators.
