一、什么是PE膜復合土工布

PE膜復(fu)合(he)土工(gong)布，簡(jian)稱復(fu)合(he)土工(gong)布，是土工(gong)合(he)成材(cai)料(liao)大家族中(zhong)的一員，是指將土工(gong)布與(yu)PE土工(gong)膜復(fu)合(he)而成的一種土工(gong)材(cai)料(liao)，又稱復(fu)合(he)土工(gong)膜。

復合(he)土(tu)工(gong)布(bu)(bu)(bu)的(de)產(chan)品(pin)(pin)品(pin)(pin)種有(you)很(hen)多(duo)，一(yi)般有(you)一(yi)布(bu)(bu)(bu)一(yi)膜、兩布(bu)(bu)(bu)一(yi)膜、多(duo)布(bu)(bu)(bu)多(duo)膜等，之所以要用復合(he)土(tu)工(gong)布(bu)(bu)(bu)，主要是因為普通的(de)土(tu)工(gong)布(bu)(bu)(bu)透(tou)水不防(fang)水，在一(yi)些水利工(gong)程(cheng)領(ling)域，就(jiu)需要用到防(fang)水性能好(hao)的(de)復合(he)土(tu)工(gong)布(bu)(bu)(bu)。

二、土工布和復合土工布有啥區別

土(tu)工(gong)(gong)布(bu)和(he)復(fu)合土(tu)工(gong)(gong)布(bu)都(dou)是土(tu)木工(gong)(gong)程中常用的(de)材料，因為土(tu)工(gong)(gong)布(bu)和(he)復(fu)合土(tu)工(gong)(gong)布(bu)的(de)外(wai)觀比較相(xiang)似，因此導致很(hen)多客戶(hu)在(zai)選擇材料時分不清楚哪種是土(tu)工(gong)(gong)布(bu)，哪種是復(fu)合土(tu)工(gong)(gong)布(bu)，下(xia)面為大家介紹(shao)一下(xia)復(fu)合土(tu)工(gong)(gong)布(bu)和(he)土(tu)工(gong)(gong)布(bu)的(de)區別：

1、生產工藝不同

土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)主(zhu)要分為長絲(si)土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)和(he)短(duan)絲(si)土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)，長絲(si)土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)是(shi)由聚(ju)酯(zhi)切片(pian)經過高溫熔融-噴絲(si)成網-針(zhen)刺而成。短(duan)絲(si)土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)是(shi)由滌綸短(duan)纖(xian)維經過設備(bei)的雜亂-梳理-成網-針(zhen)刺而成，因此土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)屬于(yu)針(zhen)刺工(gong)(gong)(gong)藝。而復合土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)則是(shi)由PE土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)膜上下(xia)兩(liang)面(mian)(mian)或者一面(mian)(mian)粘合土(tu)(tu)(tu)(tu)工(gong)(gong)(gong)布(bu)(bu)生產(chan)而成，屬于(yu)熱(re)復合工(gong)(gong)(gong)藝。

2、產品功能作用不同

無(wu)論是(shi)長絲土(tu)工(gong)(gong)(gong)布(bu)還是(shi)短絲土(tu)工(gong)(gong)(gong)布(bu)在工(gong)(gong)(gong)程中(zhong)都是(shi)主要起到過濾(lv)、反濾(lv)、加筋、保護的(de)作(zuo)用，土(tu)工(gong)(gong)(gong)布(bu)是(shi)透水(shui)(shui)不防(fang)水(shui)(shui)的(de)。而復合土(tu)工(gong)(gong)(gong)布(bu)則在工(gong)(gong)(gong)程中(zhong)起到防(fang)滲、防(fang)水(shui)(shui)、隔(ge)離的(de)作(zuo)用，復合土(tu)工(gong)(gong)(gong)布(bu)是(shi)防(fang)水(shui)(shui)防(fang)滲的(de)。

3、產品規格不同

土工布和復合土工布，其規(gui)格一般都是(shi)用克重表示的(de)，常(chang)見的(de)土(tu)工布(bu)的(de)產品(pin)規(gui)格主(zhu)要為100g/㎡-800g/㎡，而復(fu)合土(tu)工布(bu)的(de)產品(pin)規(gui)格則主(zhu)要為300g/㎡-3000g/㎡。

4、執行標準不同

長絲土(tu)工布的(de)國家執行標(biao)(biao)準為GB/T17639-2008，短絲土(tu)工布的(de)執行標(biao)(biao)準為GB/T17638-2008，而復合土(tu)工布的(de)執行標(biao)(biao)準則(ze)為GB/T17642-2008。
