國內最新聞資訊報道 記者（賈阿曉）今日獲悉，3PE防腐鋼管，是近幾年從國外引進的先進的防腐技術。它的全稱為熔結環氧/擠塑聚乙烯結構防護層，結構由以下三層組成：底層為熔結環氧；中間層為膠粘劑；麵層為擠塑聚乙烯。防護層總厚度大於2.2—2.9mm。在三層結構中，環氧底漆的主要作用是：形成連續的塗膜，與鋼管表麵直接粘結，具有很好的耐化學腐蝕性和抗陰極剝離性能；與(yu)中(zhong)間(jian)層(ceng)膠(jiao)粘(zhan)劑(ji)的(de)活(huo)性(xing)基(ji)團(tuan)反(fan)應(ying)形(xing)成(cheng)化(hua)學(xue)粘(zhan)結(jie)，保(bao)證(zheng)整(zheng)體(ti)防(fang)腐(fu)層(ceng)在(zai)較(jiao)高(gao)溫(wen)度(du)下(xia)具(ju)有(you)良(liang)好(hao)的(de)粘(zhan)結(jie)性(xing)。中(zhong)間(jian)層(ceng)通(tong)常(chang)為(wei)共(gong)聚(ju)物(wu)粘(zhan)結(jie)劑(ji)，其(qi)主(zhu)要(yao)成(cheng)分(fen)是(shi)聚(ju)烯(xi)烴(ting)，目(mu)前(qian)廣(guang)泛(fan)采(cai)用(yong)的(de)是(shi)乙(yi)烯(xi)基(ji)共(gong)聚(ju)物(wu)膠(jiao)粘(zhan)劑(ji)。共(gong)聚(ju)物(wu)膠(jiao)粘(zhan)劑(ji)的(de)極(ji)性(xing)部(bu)分(fen)官(guan)能(neng)團(tuan)與(yu)環(huan)氧(yang)底(di)漆(qi)的(de)環(huan)氧(yang)基(ji)團(tuan)可(ke)以(yi)反(fan)應(ying)生(sheng)成(cheng)氫(qing)鍵(jian)或(huo)化(hua)學(xue)鍵(jian)，使(shi)中(zhong)間(jian)層(ceng)與(yu)底(di)層(ceng)形(xing)成(cheng)良(liang)好(hao)的(de)粘(zhan)結(jie)；erfeijixingdeyixibufenyumiancengjuyixijuyouhenhaodeqinhezuoyong，suoyizhongjiancengyumiancengyejuyouhenhaodezhanjiexingneng。juyiximiancengdezhuyaozuoyongshiqijixiebaohuyufangfuzuoyong
