黑綠土工膜又叫黑綠色雙色土工膜顧名思義就是一面黑色一面綠色的一種防滲土工膜，常用于垃圾填埋場封場和雨污分流工程中，其規格常用0.75mm、0.8mm、1.0mm這三種規格。由于一面綠色覆蓋后在空中鳥瞰效果很漂亮其綠色與大自然環境相匹配，使垃圾填埋場與周圍綠色植物融為一體。所以是工程中常常使用的主要原因。垃圾填埋場封場覆蓋用的黑綠土工膜一般要求滿足國家城建標準（CJ/T234-2006標準），該標準的黑綠土工膜選擇進口純原生樹脂通過特殊配方采用三層共擠吹塑工藝生產而成。優質的黑綠雙色土工膜不僅具有良好的防滲效果還具有較高的抗穿刺能力、較強的抗拉強力、較長的抗老化能力及耐候性能和化學穩定性。其使用環境溫度為高溫110℃、低溫-70℃，并能抗強酸、堿、油的腐蝕是比較可靠的防滲材料。這種標準的黑綠土工膜具有很強的抗拉強度與斷裂伸長率，使(shi)HDPE雙(shuang)色防滲土工膜能夠在各種(zhong)不同(tong)的惡劣地質與氣候條件下使(shi)用(yong)。適應地質不均勻沉降。
雨污分流防滲土工膜
黑綠(lv)(lv)雙色(se)土(tu)工膜(mo)的綠(lv)(lv)色(se)面對原(yuan)(yuan)材料要求較(jiao)高，只有(you)優質的原(yuan)(yuan)材料及較(jiao)專業的生(sheng)產技(ji)術才能夠生(sheng)產出(chu)綠(lv)(lv)色(se)面，料質雜、品(pin)質低的回收料是無法生(sheng)產黑綠(lv)(lv)雙色(se)土(tu)工膜(mo)的，再是技(ji)術不夠過硬的話生(sheng)產出(chu)來的成品(pin)類(lei)似(si)于西瓜皮似(si)得迷彩(cai)色(se)，那樣大大影響美觀和使用。
黑(hei)綠雙色(se)土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)外(wai)觀光(guang)滑有光(guang)澤無明(ming)顯顆粒狀雜質凸起，優質的(de)(de)黑(hei)綠雙色(se)土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)不僅具(ju)有良(liang)好的(de)(de)抗曬抗老(lao)化(hua)(hua)能(neng)力(li)，黑(hei)綠雙色(se)土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)的(de)(de)綠色(se)的(de)(de)面還具(ju)有環保(bao)、美觀等特(te)(te)點。由(you)于黑(hei)色(se)吸熱(re)(re)的(de)(de)原理，完全黑(hei)色(se)的(de)(de)土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)雖然(ran)具(ju)有良(liang)好的(de)(de)抗老(lao)化(hua)(hua)抗曬能(neng)力(li)，但是(shi)因(yin)為(wei)(wei)黑(hei)色(se)吸熱(re)(re)的(de)(de)特(te)(te)性(xing)，多少也會影(ying)響到(dao)黑(hei)色(se)土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)的(de)(de)使用(yong)壽(shou)(shou)命，而黑(hei)綠雙色(se)土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)在保(bao)證了抗老(lao)化(hua)(hua)抗曬能(neng)力(li)的(de)(de)前提(ti)下，綠色(se)面還減少了土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)的(de)(de)吸熱(re)(re)能(neng)力(li)，大大延長(chang)了土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)的(de)(de)使用(yong)壽(shou)(shou)命。所以黑(hei)綠土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)是(shi)垃(la)圾(ji)填埋場封場和雨污分流工(gong)(gong)(gong)(gong)(gong)程中常見的(de)(de)材料(liao)。其(qi)焊(han)接施(shi)工(gong)(gong)(gong)(gong)(gong)跟黑(hei)色(se)土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)一樣，也應要遵循土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)焊(han)接的(de)(de)流程要求。HDPE黑(hei)綠土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)在鋪設(she)中，應盡量避免產(chan)生人(ren)為(wei)(wei)的(de)(de)折(zhe)皺(zhou)。鋪設(she)HDPE土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)時，應根據當地氣(qi)溫(wen)變化(hua)(hua)幅度和HDPE土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)的(de)(de)性(xing)能(neng)要求，預留出溫(wen)度變化(hua)(hua)引起的(de)(de)伸(shen)縮(suo)變形量，另外(wai)根據現場地形和土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)鋪設(she)的(de)(de)情況(kuang)應預留土(tu)(tu)(tu)(tu)(tu)(tu)工(gong)(gong)(gong)(gong)(gong)膜(mo)(mo)(mo)的(de)(de)伸(shen)縮(suo)量，以適應地基(ji)不均勻沉降。
