浅谈糙面土工膜的应用发展前景
聚乙烯(xi)土(tu)(tu)工膜是(shi)以PE为基础原料(liao)(liao)(liao)生产(chan)的防(fang)水(shui)阻隔性(xing)(xing)材料(liao)(liao)(liao)，具有极(ji)低的渗(shen)(shen)透性(xing)(xing)，是(shi)理想的防(fang)渗(shen)(shen)材料(liao)(liao)(liao)。PE土(tu)(tu)工膜与传统(tong)的防(fang)水(shui)材料(liao)(liao)(liao)相比，具有渗(shen)(shen)透系数低、柔性(xing)(xing)好(hao)、变形适用性(xing)(xing)强(qiang)、强(qiang)度(du)高、整体连接性(xing)(xing)好(hao)、施工方(fang)便等(deng)优点。
PE土工(gong)(gong)膜(mo)(mo)按产品外形可(ke)分为光滑面(mian)(mian)土工(gong)(gong)膜(mo)(mo)和(he)糙面(mian)(mian)土工(gong)(gong)膜(mo)(mo)。光滑面(mian)(mian)防渗膜(mo)(mo)外表细腻(ni)，摩擦(ca)系数(shu)(shu)(shu)低。糙面(mian)(mian)土工(gong)(gong)膜(mo)(mo)表面(mian)(mian)由(you)凹凸状(zhuang)结构(gou)组成，摩擦(ca)系数(shu)(shu)(shu)高。与(yu)光滑面(mian)(mian)土工(gong)(gong)膜(mo)(mo)相比，糙面(mian)(mian)土工(gong)(gong)膜(mo)(mo)不仅能(neng)应用(yong)(yong)(yong)于屋顶防漏(lou)、园林绿化、农田水渠的(de)防渗和(he)水土保持、滩涂(tu)围垦造(zao)田、环(huan)境工(gong)(gong)程中(zhong)垃(la)圾填埋、三废(fei)处理(li)和(he)环(huan)境整治、防止(zhi)沙(sha)漠化等(deng)工(gong)(gong)程，还能(neng)应用(yong)(yong)(yong)于陡坡或边(bian)坡膜(mo)(mo)体表面(mian)(mian)需要覆土等(deng)要求有较(jiao)大(da)摩擦(ca)系数(shu)(shu)(shu)的(de)工(gong)(gong)程项目(mu)中(zhong)，是山区(qu)施(shi)工(gong)(gong)、陡坡施(shi)工(gong)(gong)等(deng)工(gong)(gong)程项目(mu)的(de)首(shou)选材(cai)料。因此，水利、水电、交通、环(huan)保、建筑等(deng)各(ge)个领域都为糙面(mian)(mian)土工(gong)(gong)膜(mo)(mo)的(de)应用(yong)(yong)(yong)转型升(sheng)级提供了广阔的(de)前景。
