| 防水卷材要求有良好的耐水性，对温度变化的稳定性(高温下不流淌、不起泡、不淆动;低温下不脆裂)，一定的机械强度、延伸性和抗断裂性，要有一定的柔韧性和抗老化性等。防水卷材是一种可卷曲的片状防水材料。是建筑工程防水材料的中重要品种之一。 Waterproofing membrane requires good water resistance, stability of temperature change (no flowing, no foaming, no confusion at high temperature; no brittle cracking at low temperature), certain mechanical strength, elongation and fracture resistance, flexibility and aging resistance. Waterproof membrane is a kind of sheet waterproof material which can be curled. It is one of the most important waterproof materials in building engineering. |
