DH-814Ⅱ型聚氨酯幫助(zhu)堵漏膠是遇(yu)水(shui)(shui)(shui)即反應(ying)，由于水(shui)(shui)(shui)參與了反應(ying)，漿液不會被水(shui)(shui)(shui)稀釋沖走，這是其(qi)他灌(guan)(guan)(guan)漿材料所不具(ju)備的(de)(de)(de)優點；漿液在(zai)壓力作用(yong)(yong)下，灌(guan)(guan)(guan)入混(hun)凝 土裂縫，同(tong)(tong)時(shi)(shi)(shi)向裂縫周圍(wei)蔓延，當遇(yu)水(shui)(shui)(shui)時(shi)(shi)(shi)又發生反應(ying)，發泡膨脹，形(xing)(xing)成二次蔓延，繼續滲入混(hun)凝土縫隙，形(xing)(xing)成網(wang)狀結構，成為(wei)密度小、含水(shui)(shui)(shui)的(de)(de)(de)彈性體，有良好(hao)的(de)(de)(de) 適(shi)應(ying)變形(xing)(xing)能力，止水(shui)(shui)(shui)性好(hao)。灌(guan)(guan)(guan)漿孔(kong)(kong)的(de)(de)(de)設(she)(she)計和(he)(he)布(bu)孔(kong)(kong) 灌(guan)(guan)(guan)漿孔(kong)(kong)的(de)(de)(de)布(bu)孔(kong)(kong)有騎縫和(he)(he)斜孔(kong)(kong)兩種形(xing)(xing)式，建議根據(ju)實際情(qing)況和(he)(he)需要加以選(xuan)擇，必(bi)要時(shi)(shi)(shi)兩者并用(yong)(yong)。（1） 灌(guan)(guan)(guan)漿孔(kong)(kong)的(de)(de)(de)設(she)(she)計：灌(guan)(guan)(guan)漿孔(kong)(kong)的(de)(de)(de)位(wei)置，應(ying)使孔(kong)(kong)和(he)(he)漏水(shui)(shui)(shui)裂縫孔(kong)(kong)隙相交，并選(xuan)在(zai)漏水(shui)(shui)(shui)量深(shen)處。（2） 布(bu)孔(kong)(kong)原則：注漿孔(kong)(kong)眼(yan)的(de)(de)(de)位(wei)置和(he)(he)數量，需根據(ju)不同(tong)(tong)漏水(shui)(shui)(shui)情(qing)況進行合理(li)安排，以導出漏水(shui)(shui)(shui)為(wei)目的(de)(de)(de)，在(zai)集中漏水(shui)(shui)(shui)處布(bu)孔(kong)(kong)，裂縫大(da)(da)，水(shui)(shui)(shui)流量大(da)(da)，則孔(kong)(kong)距(ju)大(da)(da)，縫小則孔(kong)(kong)距(ju)小。

目(mu)前建(jian)(jian)筑防(fang)(fang)水(shui)(shui)材(cai)料(liao)大體上可分(fen)為(wei)五類，即瀝青防(fang)(fang)水(shui)(shui)卷材(cai)、高(gao)(gao)分(fen)子防(fang)(fang)水(shui)(shui)片材(cai)、建(jian)(jian)筑防(fang)(fang)水(shui)(shui)材(cai)料(liao)、建(jian)(jian)筑密封材(cai)料(liao)及防(fang)(fang)滲堵漏等(deng)特種(zhong)用(yong)途(tu)的(de)(de)防(fang)(fang)水(shui)(shui)材(cai)料(liao)。每種(zhong)材(cai)料(liao)各(ge)有其特性(xing)(xing)，因(yin)此必須根據(ju)的(de)(de)部位、條件、所處的(de)(de)環(huan)境、建(jian)(jian)筑的(de)(de)等(deng)級、功能(neng)需要，選(xuan)用(yong)適當的(de)(de)材(cai)料(liao)，發揮各(ge)類材(cai)料(liao)的(de)(de)特性(xing)(xing)，使之(zhi)獲得最佳防(fang)(fang)水(shui)(shui)效果(guo)。依據(ju)不同的(de)(de)工(gong)程部位來選(xuan)材(cai)，其選(xuan)擇標(biao)準也不一(yi)致。屋(wu)面(mian)(mian)因(yin)長(chang)期(qi)暴(bao)露，陽光、雪(xue)雨(yu)直接侵(qin)蝕(shi)，嚴冬酷暑溫度變(bian)化大，晝夜(ye)之(zhi)間(jian)屋(wu)面(mian)(mian)板也會發生伸縮，因(yin)此應(ying)選(xuan)用(yong)耐老化性(xing)(xing)能(neng)好(hao)的(de)(de)，且有一(yi)定(ding)延(yan)伸性(xing)(xing)的(de)(de)、耐熱度高(gao)(gao)的(de)(de)材(cai)料(liao)。如聚(ju)脂胎改(gai)性(xing)(xing)瀝青卷材(cai)、三元乙(yi)丙片材(cai)或瀝青油氈等(deng)。

屋(wu)(wu)面(mian)工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)中(zhong)，屋(wu)(wu)面(mian)防(fang)滲(shen)(shen)(shen)防(fang)漏是(shi)一(yi)項非常重要的(de)(de)質量控制工(gong)(gong)(gong)作，更(geng)是(shi)一(yi)項進行其它后續工(gong)(gong)(gong)序施(shi)工(gong)(gong)(gong)的(de)(de)基礎性工(gong)(gong)(gong)作，是(shi)其他工(gong)(gong)(gong)作優質完成(cheng)的(de)(de)前提和(he)保(bao)障。之所以重要，解釋(shi)原因如(ru)(ru)下(xia):一(yi)、發(fa)(fa)生(sheng)(sheng)滲(shen)(shen)(shen)漏的(de)(de)屋(wu)(wu)面(mian)，滲(shen)(shen)(shen)漏的(de)(de)具(ju)體部位不容易查找，處理過程受到天氣環境(jing)因素的(de)(de)影響(xiang)，處理返(fan)工(gong)(gong)(gong)周期比較(jiao)長，還不易取(qu)得較(jiao)為(wei)理想的(de)(de)預(yu)期效果。從屋(wu)(wu)面(mian)面(mian)層(ceng)到結(jie)構板面(mian)基層(ceng)工(gong)(gong)(gong)序較(jiao)多，處理起(qi)來整個過程較(jiao)為(wei)繁瑣。二、如(ru)(ru)果是(shi)開發(fa)(fa)商開發(fa)(fa)的(de)(de)商品(pin)房，屋(wu)(wu)面(mian)滲(shen)(shen)(shen)漏問題還會(hui)直接影響(xiang)開發(fa)(fa)商的(de)(de)營銷(xiao)網絡，屋(wu)(wu)面(mian)滲(shen)(shen)(shen)漏會(hui)導致小區樓盤出售困(kun)難甚至滯銷(xiao)。試想，如(ru)(ru)果小區內經常發(fa)(fa)生(sheng)(sheng)屋(wu)(wu)面(mian)滲(shen)(shen)(shen)漏的(de)(de)質量問題，有哪個小業主會(hui)買(mai)如(ru)(ru)此質量低劣的(de)(de)房產(chan)。

（1）稱重量。目前市場上的專業后澆帶堵漏很多在重量上跟桶上標明的重量會有些差距，消費者在購買時可以現場進行稱量，以免被蒙。（2）查詢防偽碼。現在造假者也會自設查詢電話和查詢條碼，消費者可上網站查找正品商標生產企業的網站，根據網站上提示的查詢電話查詢。（3）檢查防水效果。玉林市專業后澆帶堵漏以聚(ju)合(he)物(wu)防水材料(liao)為例，正(zheng)品產品可以從(cong)墻(qiang)壁(bi)、地板(ban)上用小刀取下(xia)膠皮，對折不會(hui)破，有延伸性(xing)。許多偽劣、假冒產品呈粉(fen)狀，很難從(cong)墻(qiang)上取下(xia)，對折會(hui)破。
