噴(pen)糙工藝糙面(mian)(mian)(mian)(mian)(mian)HDPE土(tu)工膜(mo)(mo)(mo)(mo)是在(zai)聚乙(yi)烯土(tu)工膜(mo)(mo)(mo)(mo)的(de)傳統生產工藝的(de)基礎上,對生產設備進行技術革(ge)新改造(zao),從而使生產出的(de)聚乙(yi)烯土(tu)工 膜(mo)(mo)(mo)(mo)表面(mian)(mian)(mian)(mian)(mian)形成(cheng)(cheng)一(yi)種顆粒狀粗糙面(mian)(mian)(mian)(mian)(mian)，提高了土(tu)工膜(mo)(mo)(mo)(mo)表面(mian)(mian)(mian)(mian)(mian)的(de)摩擦(ca)(ca)性能,同時與(yu)同規格(ge)的(de)光面(mian)(mian)(mian)(mian)(mian)膜(mo)(mo)(mo)(mo)對比,耐(nai)摩擦(ca)(ca)力(li)更強。糙面(mian)(mian)(mian)(mian)(mian)膜(mo)(mo)(mo)(mo)表面(mian)(mian)(mian)(mian)(mian)糙粒,在(zai)鋪設膜(mo)(mo)(mo)(mo)時, 會使膜(mo)(mo)(mo)(mo)與(yu)基面(mian)(mian)(mian)(mian)(mian)形成(cheng)(cheng)微(wei)小夾空層面(mian)(mian)(mian)(mian)(mian),這樣(yang)既可(ke)以增(zeng)強土(tu)工膜(mo)(mo)(mo)(mo)的(de)抗承載變(bian)形力(li)一(yi)般應用在(zai)邊坡膜(mo)(mo)(mo)(mo)體表面(mian)(mian)(mian)(mian)(mian)需要(yao)覆土(tu)要(yao)求有交大摩擦(ca)(ca)系數的(de)項目中。

　　HDPE糙(cao)面土工膜生產(chan)工藝流程：原料(liao)準(zhun)備 → 生產(chan)線準(zhun)備 → 擠(ji)出(chu)準(zhun)備 → 自動上料(liao) → 加(jia)熱擠(ji)出(chu) → 吹氣 → 循環冷卻 → 產(chan)品成型→ 牽引 → 收卷(juan) →二次噴糙(cao)→ 檢驗 → 包裝(zhuang)入(ru)庫.

　　生(sheng)產(chan)流(liu)(liu)程(cheng)(cheng)(cheng)及生(sheng)產(chan)原理:生(sheng)產(chan)流(liu)(liu)程(cheng)(cheng)(cheng)，將(jiang)干燥的(de)(de)(de)聚乙烯粒(li)子(zi)(zi)加入下(xia)料斗中(zhong)，靠粒(li)子(zi)(zi)本身的(de)(de)(de)重(zhong)量從料斗進入螺桿，當粒(li)料與(yu)螺紋斜(xie)棱接觸后(hou)、旋(xuan)轉的(de)(de)(de)斜(xie)棱面(mian)(mian)對塑料和生(sheng)產(chan)一與(yu)斜(xie)棱面(mian)(mian)相垂直的(de)(de)(de)推(tui)(tui)力(li)，將(jiang)塑料粒(li)子(zi)(zi)向前推(tui)(tui)移，推(tui)(tui)移過(guo)(guo)程(cheng)(cheng)(cheng)中(zhong)，由于塑料與(yu)螺桿、塑料與(yu)機(ji)筒(tong)(tong)之間的(de)(de)(de)摩擦(ca)以及粒(li)子(zi)(zi)間的(de)(de)(de)碰撞摩擦(ca)，同時還由于料筒(tong)(tong)外部加熱(re)而逐步溶化，熔融的(de)(de)(de)塑料經機(ji)頭過(guo)(guo)濾(lv)去雜質(zhi)從模頭摸口出來，經風環冷(leng)卻、吹脹經穩泡架人字(zi)(zi)板牽(qian)引輥(gun)卷(juan)(juan)取將(jiang)成(cheng)品薄(bo)膜(mo)卷(juan)(juan)成(cheng)筒(tong)(tong);然后(hou)使用糙面(mian)(mian)土工膜(mo)噴糙機(ji)進行二次噴糙，架人字(zi)(zi)板牽(qian)引輥(gun)卷(juan)(juan)取將(jiang)成(cheng)品薄(bo)膜(mo)卷(juan)(juan)成(cheng)筒(tong)(tong)。
