了(le)解(jie)土(tu)(tu)工(gong)(gong)膜(mo)的(de)客戶朋友(you)都(dou)知(zhi)道，土(tu)(tu)工(gong)(gong)膜(mo)分為光(guang)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)和糙(cao)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)兩種，很多市面(mian)上比(bi)較常見的(de)就是光(guang)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)產品(pin)，當然(ran)，糙(cao)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)的(de)使用范圍也是比(bi)較廣泛的(de)，關于人工(gong)(gong)湖建設使用糙(cao)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)的(de)知(zhi)識很多客戶朋友(you)也有所(suo)了(le)解(jie)，那(nei)么，今(jin)天小(xiao)編為您(nin)帶來(lai)人工(gong)(gong)湖糙(cao)面(mian)土(tu)(tu)工(gong)(gong)膜(mo)的(de)四種成型工(gong)(gong)藝。 一、軋花成糙法 將(jiang)(jiang)PE光滑(hua)面土工(gong)(gong)膜(mo)經過預熱后通過軋(ya)(ya)花(hua)輥軋(ya)(ya)花(hua)，冷(leng)卻(que)后形成糙面土工(gong)(gong)膜(mo)的(de)(de)方(fang)法(fa)(fa)。軋(ya)(ya)花(hua)成糙法(fa)(fa)與噴(pen)絲加(jia)糙法(fa)(fa)一樣，屬于二次成型，將(jiang)(jiang)光滑(hua)面土工(gong)(gong)膜(mo)進行預熱軋(ya)(ya)花(hua)得到人工(gong)(gong)湖(hu)糙面土工(gong)(gong)膜(mo)，也可將(jiang)(jiang)預熱和(he)軋(ya)(ya)花(hua)工(gong)(gong)序直(zhi)接添加(jia)到土工(gong)(gong)膜(mo)的(de)(de)生產線(xian)中，以(yi)實現人工(gong)(gong)湖(hu)糙面土工(gong)(gong)膜(mo)的(de)(de)連續化生產。 二(er)、噴絲加糙(cao)法 將PE光(guang)滑面(mian)土(tu)工(gong)(gong)膜預熱(re)，使所需加糙(cao)(cao)土(tu)工(gong)(gong)膜面(mian)層達到(dao)熱(re)變形溫度(du)以上，通過特殊的噴(pen)塑設備噴(pen)絲，將熔融狀(zhuang)塑料絲噴(pen)涂在所需加糙(cao)(cao)的土(tu)工(gong)(gong)膜表面(mian)，經(jing)過冷卻制(zhi)得粗糙(cao)(cao)面(mian)層的方法。 噴(pen)(pen)絲加糙法(fa)工(gong)藝(yi)復雜，關鍵技(ji)術在于土工(gong)膜加糙面(mian)(mian)的(de)溫度(du)控制、塑(su)料絲的(de)制造(zao)及噴(pen)(pen)涂、光面(mian)(mian)和(he)糙層絲材質(zhi)的(de)選擇等(deng)。噴(pen)(pen)絲工(gong)藝(yi)難度(du)大，糙面(mian)(mian)質(zhi)量不穩定，塑(su)料絲在土工(gong)膜表面(mian)(mian)容易脫落，從(cong)而降低其防滑(hua)性能(neng)。 噴絲(si)加(jia)糙法屬于二次成(cheng)(cheng)型，即將光滑面(mian)土(tu)工(gong)膜再一次加(jia)工(gong)成(cheng)(cheng)型，可將壓延(yan)成(cheng)(cheng)型和(he)吹塑成(cheng)(cheng)型工(gong)藝生(sheng)產的光滑面(mian)土(tu)工(gong)膜進行(xing)預熱(re)噴絲(si)，得到人(ren)工(gong)湖(hu)糙面(mian)土(tu)工(gong)膜，也(ye)可將預熱(re)和(he)噴絲(si)工(gong)序(xu)直(zhi)接添加(jia)到土(tu)工(gong)膜生(sheng)產線中，以實現人(ren)工(gong)湖(hu)糙面(mian)土(tu)工(gong)膜的連(lian)續化(hua)生(sheng)產。 三、氮氣加糙(cao)法 與(yu)發(fa)泡成糙(cao)方(fang)法(fa)類似，糙(cao)面層是將發(fa)泡劑(ji)換成氮氣(qi)直接(jie)與(yu)PE土工(gong)膜(mo)原料共(gong)(gong)混，共(gong)(gong)混后與(yu)普(pu)通層PE土工(gong)膜(mo)原料一起進入多層共(gong)(gong)擠(ji)模頭的不同流道，共(gong)(gong)同擠(ji)出成型(xing)。氮氣(qi)加(jia)糙(cao)法(fa)與(yu)化(hua)學發(fa)泡成糙(cao)法(fa)一樣，屬于一次成型(xing)，可用于吹塑成型(xing)工(gong)藝連續化(hua)生產人(ren)工(gong)湖糙(cao)面土工(gong)膜(mo)。 四、化學(xue)發泡成糙法 采(cai)用發泡(pao)劑發泡(pao)，使土(tu)工(gong)(gong)(gong)膜表(biao)面粗(cu)糙(cao)的(de)(de)一種(zhong)方(fang)法。在需加糙(cao)的(de)(de)土(tu)工(gong)(gong)(gong)膜原料中添加化(hua)學發泡(pao)劑，人(ren)工(gong)(gong)(gong)湖糙(cao)面土(tu)工(gong)(gong)(gong)膜的(de)(de)擠(ji)出成型模頭為多(duo)層共擠(ji)模頭，糙(cao)面層的(de)(de)發泡(pao)劑與PE土(tu)工(gong)(gong)(gong)膜原料的(de)(de)共混物以(yi)及普通層PE土(tu)工(gong)(gong)(gong)膜原料一起進(jin)入多(duo)層共擠(ji)模頭的(de)(de)不(bu)同流道，實現(xian)同時擠(ji)出。在擠(ji)出過程中，糙(cao)面層由于(yu)含有發泡(pao)劑，熔體在出模頭的(de)(de)瞬間因(yin)氣泡(pao)的(de)(de)產生會形成不(bu)均勻的(de)(de)粗(cu)糙(cao)突(tu)起，從而(er)形成糙(cao)面。 以(yi)上四點就是關(guan)于人工(gong)(gong)湖糙面土(tu)工(gong)(gong)膜的四種成型工(gong)(gong)藝(yi)，希望能夠幫助(zhu)客戶朋(peng)友(you)更(geng)好的了解人工(gong)(gong)湖糙面土(tu)工(gong)(gong)膜，為各(ge)工(gong)(gong)程建設的順(shun)利進行提供支(zhi)持幫助(zhu)，公(gong)司也會繼續創新發展(zhan)為更(geng)多(duo)需要的客戶提供更(geng)加(jia)滿意的人工(gong)(gong)湖糙面土(tu)工(gong)(gong)膜產品(pin)。
