2、結(jie)構膠和耐(nai)侯膠長期泡水會有什么(me)影響?大概泡多久會影響性能?

結(jie)構(gou)(gou)膠(jiao)(jiao)(jiao)和耐(nai)候膠(jiao)(jiao)(jiao)都屬于硅(gui)酮(tong)(tong)密(mi)(mi)封(feng)(feng)膠(jiao)(jiao)(jiao)（，西寧密(mi)(mi)封(feng)(feng)硅(gui)酮(tong)(tong)膠(jiao)(jiao)(jiao)，由(you)于硅(gui)酮(tong)(tong)密(mi)(mi)封(feng)(feng)膠(jiao)(jiao)(jiao)自身分子結(jie)構(gou)(gou)原因，長(chang)期泡(pao)水(shui)(shui)(shui)(shui)情況下(xia)，一(yi)些化學鍵會(hui)水(shui)(shui)(shui)(shui)解斷裂(lie)，出現粘(zhan)(zhan)接失效的(de)情況。在(zai)GB16776《建(jian)筑(zhu)硅(gui)酮(tong)(tong)結(jie)構(gou)(gou)密(mi)(mi)封(feng)(feng)膠(jiao)(jiao)(jiao)》標準中(zhong)(zhong)(zhong)，硅(gui)酮(tong)(tong)結(jie)構(gou)(gou)密(mi)(mi)封(feng)(feng)膠(jiao)(jiao)(jiao)固化后需(xu)要做粘(zhan)(zhan)接性測試，泡(pao)水(shui)(shui)(shui)(shui)測試14天，密(mi)(mi)封(feng)(feng)硅(gui)酮(tong)(tong)膠(jiao)(jiao)(jiao)批發，依然粘(zhan)(zhan)接良好。在(zai)美準ASTM 1184中(zhong)(zhong)(zhong)，結(jie)構(gou)(gou)密(mi)(mi)封(feng)(feng)膠(jiao)(jiao)(jiao)需(xu)要經過5000小時水(shui)(shui)(shui)(shui)紫外(wai)檢測，白云牌結(jie)構(gou)(gou)膠(jiao)(jiao)(jiao)可以通(tong)過測試，沒有問題(ti)。但(dan)根(gen)據硅(gui)酮(tong)(tong)膠(jiao)(jiao)(jiao)不(bu)同配方設計(ji)，大(da)概泡(pao)水(shui)(shui)(shui)(shui)幾個月到幾年，就會(hui)影響性能(neng)了。在(zai)實(shi)際工(gong)程案例中(zhong)(zhong)(zhong)，硅(gui)酮(tong)(tong)密(mi)(mi)封(feng)(feng)膠(jiao)(jiao)(jiao)是不(bu)宜用(yong)于長(chang)期泡(pao)水(shui)(shui)(shui)(shui)的(de)環境中(zhong)(zhong)(zhong)，比如水(shui)(shui)(shui)(shui)族館等(deng)水(shui)(shui)(shui)(shui)下(xia)接縫的(de)密(mi)(mi)封(feng)(feng)。

玻璃(li)膠在建(jian)筑裝(zhuang)飾(shi)材料(liao)中(zhong)(zhong)是一種很不起眼的(de)(de)輔助材料(liao)，密(mi)封硅酮膠廠家，但(dan)在建(jian)筑施工和室內裝(zhuang)修中(zhong)(zhong)卻(que)起著非常重(zhong)要(yao)的(de)(de)作(zuo)用，不能(neng)忽視它的(de)(de)質量和性(xing)(xing)能(neng)，市場上玻璃(li)膠的(de)(de)品(pin)種更是良莠不齊，怎樣才能(neng)選購一種在施工及裝(zhuang)修中(zhong)(zhong)使用效果好、黏結性(xing)(xing)強、顏色純(chun)正、價格相當(dang)的(de)(de)玻璃(li)膠呢?

(1)不能貪便宜。大多數用戶還是把便宜的產品放在首位，硅酮結構密封膠，殊不知使用膠不僅影響工程質量、使用壽命，更重要的是極易造成返工、耽誤工期，甚至出現責任事故。要注意防霉。

玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)按性(xing)(xing)(xing)(xing)能分為(wei)兩種(zhong):中(zhong)性(xing)(xing)(xing)(xing)玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)和酸(suan)(suan)性(xing)(xing)(xing)(xing)玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)。一般(ban)用(yong)(yong)于家裝粘(zhan)接(jie)。家裝中(zhong)一般(ban)使用(yong)(yong)玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)的(de)(de)地方(fang)有:木(mu)(mu)線(xian)背(bei)(bei)面啞(ya)口(kou)處、潔具、坐(zuo)便器、衛生間里(li)的(de)(de)化妝鏡、洗手池與墻(qiang)面的(de)(de)縫(feng)隙處等等，這(zhe)(zhe)些地方(fang)要用(yong)(yong)不(bu)同性(xing)(xing)(xing)(xing)能的(de)(de)玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)。中(zhong)性(xing)(xing)(xing)(xing)玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)粘(zhan)接(jie)力比較(jiao)弱，一般(ban)用(yong)(yong)在(zai)衛生間鏡子背(bei)(bei)面這(zhe)(zhe)些不(bu)需要很強粘(zhan)接(jie)力的(de)(de)地方(fang)。中(zhong)性(xing)(xing)(xing)(xing)玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)在(zai)家裝中(zhong)使用(yong)(yong)比較(jiao)多，主(zhu)要因為(wei)它不(bu)會腐(fu)蝕(shi)物(wu)體，而酸(suan)(suan)性(xing)(xing)(xing)(xing)玻(bo)(bo)(bo)(bo)璃(li)(li)膠(jiao)(jiao)一般(ban)用(yong)(yong)在(zai)木(mu)(mu)線(xian)背(bei)(bei)面的(de)(de)啞(ya)口(kou)處，粘(zhan)接(jie)力很強。
