一、什么是糙面hdpe土工膜
糙面hdpe土工膜,又稱糙面土工膜,是以高密(mi)度聚(ju)乙(yi)烯樹脂顆粒為原料(liao)經過吹膜三層共擠起糙制(zhi)成(cheng)的土工材料(liao),由約(yue)97.5%高品質(zhi)聚(ju)乙(yi)烯,2.5%的碳黑、微(wei)量的抗氧劑(ji)和熱穩定劑(ji)制(zhi)成(cheng)。
糙(cao)面(mian)HDPE土(tu)(tu)工(gong)(gong)膜(mo)包(bao)括(kuo)單糙(cao)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)和雙糙(cao)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)以(yi)及單雙柱(zhu)點土(tu)(tu)工(gong)(gong)膜(mo),在工(gong)(gong)程中主要是加大與基底和坡(po)面(mian)的摩(mo)擦系數,增大摩(mo)擦力,起到防滑的作用。
二、土工膜糙面和光面有什么區別
土(tu)工膜有(you)糙面和光(guang)面兩種,它們之間有(you)明顯(xian)的差別:
1、外觀不同
糙面土工膜(mo)的外表是粗(cu)糙的,光(guang)(guang)(guang)面土工膜(mo)則是光(guang)(guang)(guang)面鏡子面,可以(yi)反光(guang)(guang)(guang)射影,看(kan)起來比(bi)較亮。
2、性能不同
糙面(mian)土(tu)(tu)工(gong)膜(mo)比(bi)光面(mian)土(tu)(tu)工(gong)膜(mo)摩(mo)擦(ca)系(xi)數更(geng)大,體現表面(mian)摩(mo)擦(ca)系(xi)數的一個重要指標,就是(shi)土(tu)(tu)工(gong)膜(mo)表面(mian)剪切強度和摩(mo)擦(ca)角(jiao)。另外,糙面(mian)土(tu)(tu)工(gong)膜(mo)比(bi)光面(mian)土(tu)(tu)工(gong)膜(mo)有更(geng)好的斷裂(lie)伸(shen)長率、耐環境應(ying)力開裂(lie)性能(neng)以及環境適應(ying)性。
3、應用不同
糙面土工(gong)(gong)膜主(zhu)要(yao)用在一些日常(chang)生活垃圾填埋場、尾礦庫(ku)等項目(mu)的(de)邊坡(po)防滑防滲和封場;而光面防滲膜則是(shi)用在填埋場底(di)層、人工(gong)(gong)湖、水庫(ku)等工(gong)(gong)程防滲主(zhu)體中(zhong)。
4、價格不同
糙面(mian)(mian)的加工(gong)(gong)成本要高于(yu)光面(mian)(mian)土工(gong)(gong)膜(mo),糙面(mian)(mian)土工(gong)(gong)膜(mo)加工(gong)(gong)工(gong)(gong)藝更特殊、復雜,因此價格也會貴一些。
三、糙面hdpe土工膜和光面hdpe土工膜哪個好
糙面(mian)(mian)土(tu)工(gong)膜和光(guang)面(mian)(mian)土(tu)工(gong)膜相比,各(ge)有各(ge)的優(you)勢,并不一定哪(na)種(zhong)更好,糙面(mian)(mian)土(tu)工(gong)膜有粗糙的顆粒,可以增加摩擦系數和附著力,非(fei)常適合(he)用于(yu)各(ge)種(zhong)堤壩加固,而光(guang)面(mian)(mian)在(zai)這方面(mian)(mian)就沒有糙面(mian)(mian)有優(you)勢;但(dan)光(guang)面(mian)(mian)土(tu)工(gong)膜的優(you)勢在(zai)于(yu)造價要(yao)低一些,如(ru)何選擇(ze)主要(yao)看應用領(ling)域(yu)。
