凱倫建材防水卷材系列：防水卷材有哪些性能？

1.耐水(shui)(shui)(shui)(shui)性(xing)(xing)。耐水(shui)(shui)(shui)(shui)性(xing)(xing)是指(zhi)在(zai)(zai)水(shui)(shui)(shui)(shui)的作用下(xia)和被(bei)水(shui)(shui)(shui)(shui)浸潤后(hou)其性(xing)(xing)能基(ji)本不(bu)變(bian)，在(zai)(zai)壓力(li)水(shui)(shui)(shui)(shui)作用下(xia)具有不(bu)透水(shui)(shui)(shui)(shui)性(xing)(xing)，常用不(bu)透水(shui)(shui)(shui)(shui)性(xing)(xing)、吸水(shui)(shui)(shui)(shui)性(xing)(xing)等指(zhi)標表示；

2.溫(wen)度(du)穩定性(xing)(xing)(xing)。溫(wen)度(du)穩定性(xing)(xing)(xing)指在高溫(wen)下(xia)(xia)不(bu)流淌、不(bu)起泡、不(bu)滑動，低溫(wen)下(xia)(xia)不(bu)脆(cui)裂的(de)(de)性(xing)(xing)(xing)能(neng)(neng)，即在一定溫(wen)度(du)變(bian)化下(xia)(xia)保持原有性(xing)(xing)(xing)能(neng)(neng)的(de)(de)能(neng)(neng)力。常用耐(nai)熱(re)度(du)、耐(nai)熱(re)性(xing)(xing)(xing)等指標表(biao)示；

3.機械強度(du)、延伸性(xing)和抗斷(duan)裂性(xing)。它指防水卷材承受一(yi)定荷載(zai)、應力或(huo)在一(yi)定變(bian)形(xing)的條件下不(bu)斷(duan)裂的性(xing)能。常用拉力、拉伸強度(du)和斷(duan)裂伸長率等指標表示(shi)；

4.柔韌性(xing)(xing)(xing)。柔韌性(xing)(xing)(xing)指在(zai)低溫(wen)條件(jian)下(xia)保持柔韌性(xing)(xing)(xing)的性(xing)(xing)(xing)能。它對保證(zheng)易于(yu)施工、不脆裂十分重(zhong)要。常用(yong)柔度、低溫(wen)彎折性(xing)(xing)(xing)等指標(biao)表示；

5.大(da)氣穩(wen)定性(xing)。大(da)氣穩(wen)定性(xing)指(zhi)在陽光、熱(re)、臭氧及其他化學侵(qin)(qin)蝕介質等(deng)因素(su)的長期(qi)綜合作用下抵抗侵(qin)(qin)蝕的能力。常用耐老化性(xing)、熱(re)老化保持(chi)率(lv)的等(deng)指(zhi)標表示。
