1、高強結(jie)構膠在什么情況(kuang)下(xia)需要論證?

在(zai)玻(bo)璃幕(mu)墻(qiang)用硅(gui)(gui)(gui)酮(tong)結構(gou)密(mi)(mi)封膠(jiao)超規(gui)(gui)范設(she)(she)計(ji)的(de)(de)(de)時候，幕(mu)墻(qiang)項(xiang)目(mu)需要(yao)使(shi)用白(bai)云牌超硅(gui)(gui)(gui)酮(tong)結構(gou)密(mi)(mi)封膠(jiao)來提高f1值(硅(gui)(gui)(gui)酮(tong)結構(gou)密(mi)(mi)封膠(jiao)在(zai)風(feng)荷載或(huo)作用下的(de)(de)(de)強(qiang)度(du)設(she)(she)計(ji)值)、f2值(硅(gui)(gui)(gui)酮(tong)結構(gou)密(mi)(mi)封膠(jiao)在(zai)荷載下的(de)(de)(de)強(qiang)度(du)設(she)(she)計(ji)值)、δ值(硅(gui)(gui)(gui)酮(tong)結構(gou)密(mi)(mi)封膠(jiao)的(de)(de)(de)變位承受(shou)能力，解決設(she)(she)計(ji)過程(cheng)遇到的(de)(de)(de)硅(gui)(gui)(gui)酮(tong)結構(gou)膠(jiao)設(she)(she)計(ji)寬度(du)或(huo)者厚度(du)超出規(gui)(gui)范值的(de)(de)(de)問題。這種超規(gui)(gui)范設(she)(she)計(ji)的(de)(de)(de)可行(xing)(xing)性，需要(yao)甲(jia)方向項(xiang)目(mu)所在(zai)省(sheng)份的(de)(de)(de)住房(fang)和(he)城鄉建設(she)(she)廳進行(xing)(xing)申請(qing)，由住房(fang)和(he)城鄉建設(she)(she)廳安排時間，組，進行(xing)(xing)論證。

幕(mu)(mu)墻膠是(shi)建(jian)筑工(gong)(gong)(gong)程上的(de)材(cai)(cai)料，整棟建(jian)筑的(de)幕(mu)(mu)墻結構都(dou)(dou)需要用(yong)到它，可謂是(shi)“隱形的(de)功(gong)臣”。幕(mu)(mu)墻膠強度高(gao)、抗剝離、耐(nai)沖擊、施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝簡便(bian)，廣泛(fan)地應用(yong)于(yu)施(shi)工(gong)(gong)(gong)安裝、裝修、密封、結構粘(zhan)接劑等(deng)領域(yu)。現代(dai)建(jian)筑的(de)發展(zhan)方向將(jiang)是(shi)設計標（準化(hua)(hua)、施(shi)工(gong)(gong)(gong)機械化(hua)(hua)、構件預制（化(hua)(hua)及建(jian)材(cai)(cai)的(de)輕質、高(gao)強和多功(gong)能化(hua)(hua)。而幕(mu)(mu)墻工(gong)(gong)(gong)程膠的(de)廣泛(fan)應用(yong)，將(jiang)加快此四化(hua)(hua)的(de)進程，并且在(zai)(zai)提高(gao)施(shi)工(gong)(gong)(gong)速(su)度、美化(hua)(hua)建(jian)筑物、改進建(jian)筑質量、節省工(gong)(gong)(gong)時(shi)與能源環(huan)保(bao)、減少污染等(deng)諸多方面都(dou)(dou)有重(zhong)要意義，因此幕(mu)(mu)墻膠已成為重(zhong)要的(de)化(hua)(hua)學(xue)建(jian)材(cai)(cai)之一。起到關鍵性作用(yong)的(de)幕(mu)(mu)墻工(gong)(gong)(gong)程膠在(zai)(zai)施(shi)工(gong)(gong)(gong)中會遇到哪些常見問(wen)題?我們如(ru)何來應對?

．注膠時接口潮濕：

在(zai)(zai)室(shi)外(wai)作(zuo)業，撫順硅(gui)酮(tong)(tong)膠(jiao)(jiao)(jiao)(jiao)，經(jing)常遇到降(jiang)雨，特別是(shi)在(zai)(zai)南(nan)方的夏季(ji)，幾乎天天都要下雨，硅(gui)酮(tong)(tong)膠(jiao)(jiao)(jiao)(jiao)廠，如果降(jiang)雨后(hou)，硅(gui)酮(tong)(tong)膠(jiao)(jiao)(jiao)(jiao)密封膠(jiao)(jiao)(jiao)(jiao)，接(jie)口里面(mian)潮濕未干就直接(jie)注膠(jiao)(jiao)(jiao)(jiao)，等(deng)太陽照射(she)粘結基(ji)材及膠(jiao)(jiao)(jiao)(jiao)縫(feng)(feng)時(shi)接(jie)口里面(mian)的溫度升高，膠(jiao)(jiao)(jiao)(jiao)縫(feng)(feng)里面(mian)的潮氣蒸發，會(hui)把未固化的、比較(jiao)軟的膠(jiao)(jiao)(jiao)(jiao)縫(feng)(feng)隆起泡，有時(shi)聚(ju)乙烯(xi)泡沫墊桿潮濕也會(hui)引起膠(jiao)(jiao)(jiao)(jiao)縫(feng)(feng)起泡。所以(yi)，施工時(shi)不可一味求(qiu)進度，等(deng)到接(jie)口內干燥后(hou)，再注膠(jiao)(jiao)(jiao)(jiao)，可避免上述(shu)情況。
