一、什么是糙面hdpe土工膜

糙面(mian)(mian)hdpe土工(gong)膜(mo)，又稱糙面(mian)(mian)土工(gong)膜(mo)，是以高(gao)(gao)密(mi)度(du)聚(ju)乙烯樹(shu)脂(zhi)顆粒為原料經過吹膜(mo)三層共擠(ji)起糙制成(cheng)的(de)土工(gong)材料，由約97.5%高(gao)(gao)品質聚(ju)乙烯，2.5%的(de)碳黑、微量的(de)抗氧劑(ji)(ji)和熱穩定(ding)劑(ji)(ji)制成(cheng)。

糙面(mian)(mian)HDPE土(tu)工(gong)(gong)膜(mo)包括單(dan)糙面(mian)(mian)土(tu)工(gong)(gong)膜(mo)和雙糙面(mian)(mian)土(tu)工(gong)(gong)膜(mo)以及(ji)單(dan)雙柱點土(tu)工(gong)(gong)膜(mo)，在工(gong)(gong)程中主(zhu)要是(shi)加大(da)與基底和坡(po)面(mian)(mian)的(de)摩擦系數(shu)，增(zeng)大(da)摩擦力，起到防(fang)滑的(de)作(zuo)用(yong)。

二、土工膜糙面和光面有什么區別

土工膜有糙面和光面兩種，它們之(zhi)間有明顯的差別：

1、外觀不同

糙(cao)(cao)面(mian)土(tu)(tu)工膜的外表(biao)是粗糙(cao)(cao)的，光(guang)面(mian)土(tu)(tu)工膜則是光(guang)面(mian)鏡子面(mian)，可以反光(guang)射影，看起(qi)來比較亮。

2、性能不同

糙(cao)面(mian)土工(gong)(gong)膜(mo)(mo)(mo)比(bi)光面(mian)土工(gong)(gong)膜(mo)(mo)(mo)摩(mo)(mo)擦系(xi)數(shu)更大，體現表(biao)面(mian)摩(mo)(mo)擦系(xi)數(shu)的一個重要指標，就是土工(gong)(gong)膜(mo)(mo)(mo)表(biao)面(mian)剪切強度和(he)摩(mo)(mo)擦角。另外，糙(cao)面(mian)土工(gong)(gong)膜(mo)(mo)(mo)比(bi)光面(mian)土工(gong)(gong)膜(mo)(mo)(mo)有更好(hao)的斷裂(lie)伸長(chang)率、耐(nai)環境應(ying)(ying)力開(kai)裂(lie)性(xing)能以(yi)及環境適應(ying)(ying)性(xing)。

3、應用不同

糙面土工(gong)膜(mo)主(zhu)要用(yong)在一些日常(chang)生活垃圾填(tian)埋(mai)場(chang)、尾礦庫等項目(mu)的邊坡(po)防(fang)滑防(fang)滲(shen)和封(feng)場(chang)；而光面防(fang)滲(shen)膜(mo)則是(shi)用(yong)在填(tian)埋(mai)場(chang)底層(ceng)、人工(gong)湖、水庫等工(gong)程防(fang)滲(shen)主(zhu)體中。

4、價格不同

糙(cao)(cao)面的加工(gong)(gong)成(cheng)本要高于光面土(tu)工(gong)(gong)膜，糙(cao)(cao)面土(tu)工(gong)(gong)膜加工(gong)(gong)工(gong)(gong)藝更(geng)特殊、復雜，因此(ci)價格也會(hui)貴一些(xie)。

三、糙面hdpe土工膜和光面hdpe土工膜哪個好

糙面(mian)(mian)(mian)土(tu)(tu)工(gong)(gong)膜(mo)和光(guang)(guang)面(mian)(mian)(mian)土(tu)(tu)工(gong)(gong)膜(mo)相比，各有各的優勢，并不一定哪種更好，糙面(mian)(mian)(mian)土(tu)(tu)工(gong)(gong)膜(mo)有粗糙的顆粒，可(ke)以增(zeng)加(jia)摩擦系(xi)數和附著力，非常適合用(yong)于(yu)各種堤壩(ba)加(jia)固，而光(guang)(guang)面(mian)(mian)(mian)在這方面(mian)(mian)(mian)就(jiu)沒(mei)有糙面(mian)(mian)(mian)有優勢；但光(guang)(guang)面(mian)(mian)(mian)土(tu)(tu)工(gong)(gong)膜(mo)的優勢在于(yu)造價要低一些(xie)，如(ru)何選擇主要看(kan)應用(yong)領域。
