一、998結構膠與995的區別

1、998結(jie)構(gou)膠可(ke)以(yi)(yi)用(yong)(yong)于建(jian)筑性(xing)結(jie)構(gou)的粘(zhan)貼(tie)，還可(ke)以(yi)(yi)用(yong)(yong)于地面(mian)瓷磚(zhuan)的粘(zhan)接上，可(ke)以(yi)(yi)增(zeng)強瓷磚(zhuan)的耐沖(chong)擊性(xing)與抗脫離性(xing)，另外，在金屬(shu)、陶瓷、塑料、橡膠等材料上，也可(ke)以(yi)(yi)用(yong)(yong)998結(jie)構(gou)膠來粘(zhan)貼(tie)，但是其(qi)沒有防水功能。

2、995結構膠(jiao)的強度(du)比(bi)較高，可(ke)以承受較大的荷載，其特點是(shi)耐老化、耐腐蝕(shi)、抗剝離、耐沖擊(ji)等等，適用(yong)于玻璃、鋁合金、瓷磚等裝飾材料的粘貼上。

3、998結構膠與995結構膠的固化時間不(bu)一樣，適(shi)用的材料也不(bu)一樣，所以兩者不(bu)能混合使(shi)用，也不(bu)能互相(xiang)代(dai)替(ti)使(shi)用，在(zai)使(shi)用前要先(xian)了(le)解清楚(chu)它們的特(te)性。

二、怎么選購結構膠

1、選購(gou)結(jie)構(gou)(gou)(gou)(gou)膠(jiao)(jiao)(jiao)(jiao)需明白(bai)專膠(jiao)(jiao)(jiao)(jiao)專用(yong)(yong)(yong)。工程結(jie)構(gou)(gou)(gou)(gou)加固(gu)(gu)用(yong)(yong)(yong)結(jie)構(gou)(gou)(gou)(gou)膠(jiao)(jiao)(jiao)(jiao)不(bu)是單一的(de)(de)一種(zhong)膠(jiao)(jiao)(jiao)(jiao)，它有(you)很多(duo)分(fen)(fen)類(lei)(lei)。比如(ru)，按(an)膠(jiao)(jiao)(jiao)(jiao)接基材的(de)(de)不(bu)同，分(fen)(fen)為混凝土用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)、結(jie)構(gou)(gou)(gou)(gou)鋼用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)、砌體用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)和(he)木材用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)等(deng)，每種(zhong)膠(jiao)(jiao)(jiao)(jiao)還應按(an)其現場固(gu)(gu)化(hua)條件(jian)的(de)(de)不(bu)同，劃分(fen)(fen)為室溫固(gu)(gu)化(hua)型、低溫固(gu)(gu)化(hua)型和(he)高濕面（或水下）固(gu)(gu)化(hua)型等(deng)三種(zhong)類(lei)(lei)型結(jie)構(gou)(gou)(gou)(gou)膠(jiao)(jiao)(jiao)(jiao)。除(chu)此(ci)之外，結(jie)構(gou)(gou)(gou)(gou)膠(jiao)(jiao)(jiao)(jiao)應按(an)使(shi)用(yong)(yong)(yong)場景分(fen)(fen)類(lei)(lei)，不(bu)能混淆(xiao)使(shi)用(yong)(yong)(yong)。比如(ru)植(zhi)(zhi)筋(jin)膠(jiao)(jiao)(jiao)(jiao)與粘(zhan)(zhan)鋼膠(jiao)(jiao)(jiao)(jiao)，《建筑結(jie)構(gou)(gou)(gou)(gou)加固(gu)(gu)工程施工質量(liang)驗收規(gui)范》GB50550-2010中規(gui)定，加固(gu)(gu)過程中，嚴禁使(shi)用(yong)(yong)(yong)“植(zhi)(zhi)筋(jin)-粘(zhan)(zhan)鋼兩用(yong)(yong)(yong)膠(jiao)(jiao)(jiao)(jiao)”。如(ru)果讓粘(zhan)(zhan)鋼膠(jiao)(jiao)(jiao)(jiao)也(ye)使(shi)用(yong)(yong)(yong)植(zhi)(zhi)筋(jin)膠(jiao)(jiao)(jiao)(jiao)的(de)(de)配(pei)方，這對粘(zhan)(zhan)鋼而言，勢必會留(liu)下安(an)全隱(yin)患。

2、結構膠(jiao)選用時，應根據(ju)各類工(gong)程結構安(an)全使(shi)用所要求的性能(neng)和質量“對癥下藥”，才能(neng)使(shi)結構膠(jiao)發(fa)揮良好(hao)的使(shi)用性能(neng)、耐久性能(neng)和經濟性，保障結構的安(an)全。

3、就像(xiang)買日常用(yong)品一樣，我們(men)往往十(shi)分(fen)關(guan)注質量(liang)(liang)問題，對(dui)于(yu)結(jie)構(gou)膠(jiao)也是(shi)如此，質量(liang)(liang)是(shi)前提。為了加(jia)強對(dui)工程結(jie)構(gou)加(jia)固中應用(yong)的有關(guan)材(cai)料(liao)及制(zhi)品的質量(liang)(liang)控制(zhi)和(he)(he)技術管理，確保工程結(jie)構(gou)加(jia)固工程的質量(liang)(liang)和(he)(he)安(an)(an)全，行(xing)業內通(tong)過了對(dui)結(jie)構(gou)膠(jiao)的安(an)(an)全性(xing)鑒(jian)定報(bao)告。應當明白(bai)，安(an)(an)全性(xing)鑒(jian)定報(bao)告必須為選用(yong)結(jie)構(gou)膠(jiao)的依據。
