土工布按照生產(chan)工藝如何分(fen)類:
土工布按制造方法不同,分為織造土工布(有紡(fang))、非織(zhi)造土(tu)工(gong)布(bu)(無紡(fang))、復合型土(tu)工(gong)布(bu)、濕法成網土(tu)工(gong)布(bu)。其中:
1、織造(zao)土工(gong)布(有紡)由合(he)成(cheng)纖(xian)維(wei)長絲(si)(丙綸、滌綸、錦綸、維(wei)綸、乙綸等)或(huo)塑料扁絲(si)、塑料裂膜絲(si)按(an)一定方向排(pai)列機織的土工(gong)織物;
2、非織造土工(gong)布(無(wu)紡)由短(duan)纖(xian)維或(huo)(huo)長絲(si)按隨(sui)機排列(lie)或(huo)(huo)定向排列(lie)制(zhi)成的薄絮墊(dian),經機械結合、熱粘或(huo)(huo)化粘而(er)成的織物(wu);
3、濕法成網土工(gong)布由短切聚酯纖維(wei)、玻璃纖維(wei)為原料(liao)在水中分散后,經抄取、脫水、施膠(jiao)、干燥等(deng)工(gong)藝過(guo)程(cheng)制造而(er)成;
4、復(fu)(fu)(fu)合(he)型土(tu)(tu)工(gong)布(bu):以聚合(he)物為原料制成的(de)(de)長絲機(ji)織(zhi)土(tu)(tu)工(gong)布(bu)或裂膜絲機(ji)織(zhi)土(tu)(tu)工(gong)布(bu)(編織(zhi)土(tu)(tu)工(gong)布(bu))與短纖(xian)針刺非(fei)織(zhi)種土(tu)(tu)工(gong)布(bu)經(jing)針刺復(fu)(fu)(fu)合(he)而成的(de)(de)土(tu)(tu)工(gong)織(zhi)物。具有(you)防護、加筋功能(neng),主要用于軟土(tu)(tu)地基(ji)加筋補強、路堤基(ji)底加筋等工(gong)程(cheng)領域中。按產品(pin)結(jie)構分為二層復(fu)(fu)(fu)合(he)和三(san)層復(fu)(fu)(fu)合(he)。
5、土工布按原料不同,分為 ① 滌綸短纖針刺非織造土工布;② 聚丙烯短纖針刺非織造土工布;③ 聚酯長絲紡粘針刺非織造土工布;④ 丙綸長絲機織土工布;⑤
滌綸長絲(si)機織(zhi)土工(gong)(gong)(gong)(gong)布;⑥玄(xuan)武巖纖(xian)維機織(zhi)土工(gong)(gong)(gong)(gong)布;⑦聚丙烯(xi)裂膜絲(si)機織(zhi)土工(gong)(gong)(gong)(gong)布;⑧ 塑料(liao)扁絲(si)編織(zhi)土工(gong)(gong)(gong)(gong)布;⑨ 聚酯玻纖(xian)濕法(fa)非(fei)織(zhi)造(zao)土工(gong)(gong)(gong)(gong)布;⑩營養土工(gong)(gong)(gong)(gong)布。
6、復合土工布按材質組成分為:①長絲機織/短纖非織造復合土工布(FW/SNG);②裂膜絲機織/短纖非織造復合土工布(SWG/SNG);③
塑料扁絲編織/短纖非織造復合土工(GFW/SNG);④ 短纖非織造/長絲機織/短纖非織造復合土工布(SNG/FW/SNG);⑤
短纖非織(zhi)造/裂膜絲(si)機織(zhi)/短纖非織(zhi)造復(fu)合土工布(SNG/SWG/SNG);⑥ 短纖非織(zhi)/塑料(liao)編(bian)織(zhi)扁(bian)織(zhi)/短纖非織(zhi)造復(fu)合土工布(SNG/SWG/SNG)。
