Performance introduction of waterproof membrane
1.耐水性
1. water resistance
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。
Water resistance refers to the fact that its performance is basically unchanged under the action of water and after being soaked by water, and it is impermeable under the action of pressure water. It is often expressed by such indicators as water permeability and water absorption.
2.温度稳定性
2. Temperature stability
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。
Temperature stability refers to the performance of non-flowing, non-foaming, non-sliding at high temperature and non-brittle cracking at low temperature, that is, the ability to maintain the original performance under certain temperature changes. Commonly used heat resistance, heat resistance and other indicators.
3.机械强度、延伸性和抗断裂性
3. Mechanical strength, elongation and fracture resistance
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。
It refers to the performance of waterproofing membrane under certain load, stress or deformation conditions. Tensile force, tensile strength and elongation at break are commonly used.
4.柔韧性
4. flexibility
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。
Flexibility refers to the ability to maintain flexibility at low temperatures. It is very important to ensure easy construction and non-brittle cracking. Commonly used flexibility, low temperature bending and other indicators.fangyanban.75ix.com   gougaiban.75ix.com      buxiugang.75ix.com
