中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)一種良好的(de)(de)隔(ge)熱、隔(ge)音、美(mei)觀(guan)適用(yong)(yong)、并可(ke)(ke)(ke)降低(di)建筑物自重的(de)(de)新型(xing)建筑材料，它是用(yong)(yong)兩(liang)片(pian)(pian)（或三片(pian)(pian)）玻(bo)(bo)璃(li)(li)(li)，使(shi)用(yong)(yong)高(gao)強(qiang)度高(gao)氣密(mi)性復合粘(zhan)結劑(ji)(ji)，將玻(bo)(bo)璃(li)(li)(li)片(pian)(pian)與內(nei)含(han)干燥(zao)劑(ji)(ji)的(de)(de)鋁(lv)合金框架粘(zhan)結，制(zhi)成的(de)(de)高(gao)效(xiao)(xiao)能(neng)隔(ge)音隔(ge)熱玻(bo)(bo)璃(li)(li)(li)。中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)多種性能(neng)優越于普通(tong)雙層(ceng)玻(bo)(bo)璃(li)(li)(li)，因此得到了世界各國的(de)(de)認可(ke)(ke)(ke)，中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)是將兩(liang)片(pian)(pian)或多片(pian)(pian)玻(bo)(bo)璃(li)(li)(li)以有(you)效(xiao)(xiao)支撐(cheng)均勻隔(ge)開并周(zhou)邊粘(zhan)結密(mi)封，使(shi)玻(bo)(bo)璃(li)(li)(li)層(ceng)間(jian)形成有(you)干燥(zao)氣體(ti)空(kong)(kong)間(jian)的(de)(de)玻(bo)(bo)璃(li)(li)(li)制(zhi)品。其(qi)(qi)主要(yao)(yao)材料是玻(bo)(bo)璃(li)(li)(li)、鋁(lv)間(jian)隔(ge)條、彎角栓(shuan)、丁(ding)基橡膠、聚硫膠、干燥(zao)劑(ji)(ji)。中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)主要(yao)(yao)用(yong)(yong)于需(xu)要(yao)(yao)采暖、空(kong)(kong)調(diao)、防止(zhi)噪音或結露以及(ji)需(xu)要(yao)(yao)無直射陽(yang)光和特(te)殊光的(de)(de)建筑物上(shang)。廣(guang)泛應用(yong)(yong)于住(zhu)宅、飯(fan)店(dian)、賓館、辦公樓、學校、醫院、商店(dian)等(deng)需(xu)要(yao)(yao)室內(nei)空(kong)(kong)調(diao)的(de)(de)場(chang)合。也可(ke)(ke)(ke)用(yong)(yong)于火車、汽車、輪船、冷凍(dong)柜的(de)(de)門(men)窗等(deng)處。中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)現在市場(chang)上(shang)運用(yong)(yong)的(de)(de)很廣(guang)泛，對于中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)承載(zai)性能(neng)要(yao)(yao)求也越加重要(yao)(yao)，其(qi)(qi)中(zhong)(zhong)(zhong)影響中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)承載(zai)性能(neng)的(de)(de)主要(yao)(yao)因素為(wei)中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)強(qiang)度、中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)剛(gang)度及(ji)中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)(bo)璃(li)(li)(li)中(zhong)(zhong)(zhong)空(kong)(kong)層(ceng)密(mi)封性能(neng)。

1.中空(kong)玻璃的強度(du)及剛度(du)

中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)(li)(li)(li)強(qiang)度是指(zhi)中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)(li)(li)(li)抵抗外載(zai)(zai)作用的(de)(de)能(neng)力(li)，剛(gang)度是指(zhi)中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)(li)(li)(li)承(cheng)載(zai)(zai)變形的(de)(de)能(neng)力(li)。顯然，在玻(bo)璃(li)(li)(li)(li)材料給定后(hou)，比如普通平板(ban)玻(bo)璃(li)(li)(li)(li)或鋼(gang)化玻(bo)璃(li)(li)(li)(li)，那么根據(ju)玻(bo)璃(li)(li)(li)(li)強(qiang)度設計理論，玻(bo)璃(li)(li)(li)(li)原片的(de)(de)斷裂強(qiang)度就(jiu)確定下來了。因(yin)此(ci)，要(yao)使(shi)中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)(li)(li)(li)承(cheng)載(zai)(zai)能(neng)力(li)提高，就(jiu)必須在同載(zai)(zai)荷作用下使(shi)玻(bo)璃(li)(li)(li)(li)表面(mian)彎拉應力(li)更小(xiao)，這就(jiu)與中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)(li)(li)(li)原片尺寸（各原片的(de)(de)長度、寬度、長寬比與厚(hou)度）及中(zhong)(zhong)(zhong)空(kong)(kong)層厚(hou)度有關。外載(zai)(zai)作用下直接分配到每片玻(bo)璃(li)(li)(li)(li)上的(de)(de)載(zai)(zai)荷大小(xiao)決定著(zhu)中(zhong)(zhong)(zhong)空(kong)(kong)玻(bo)璃(li)(li)(li)(li)的(de)(de)承(cheng)載(zai)(zai)能(neng)力(li)。

由(you)于中(zhong)(zhong)空玻(bo)璃(li)是由(you)兩(liang)片（或兩(liang)片以(yi)上）玻(bo)璃(li)構成，周邊密封形成一(yi)(yi)個密封的空氣層，中(zhong)(zhong)空玻(bo)璃(li)在(zai)一(yi)(yi)面玻(bo)璃(li)受(shou)到載(zai)荷作用時(shi)，受(shou)力面玻(bo)璃(li)變形壓縮中(zhong)(zhong)空層氣體，氣體壓強(qiang)增(zeng)大，將部(bu)分載(zai)荷傳送(song)給另一(yi)(yi)面玻(bo)璃(li)，因此(ci)在(zai)氣體密封狀態下，中(zhong)(zhong)空玻(bo)璃(li)是兩(liang)片玻(bo)璃(li)共同承擔載(zai)荷，兩(liang)片玻(bo)璃(li)同時(shi)變形。

2.中(zhong)空(kong)層失(shi)效狀態下中(zhong)空(kong)玻璃承載特性

在中(zhong)空(kong)(kong)層(ceng)氣(qi)(qi)體(ti)(ti)密封(feng)的(de)情(qing)況(kuang)下(xia)，氣(qi)(qi)體(ti)(ti)的(de)傳(chuan)遞作用能(neng)夠將一部分外荷載傳(chuan)遞給另一片(pian)玻(bo)璃(li)，但是當氣(qi)(qi)體(ti)(ti)層(ceng)泄漏時(shi)，中(zhong)空(kong)(kong)層(ceng)氣(qi)(qi)體(ti)(ti)則完全喪失了傳(chuan)遞荷載的(de)作用，此時(shi)，中(zhong)空(kong)(kong)玻(bo)璃(li)承(cheng)受(shou)荷載完全由直接(jie)受(shou)力(li)的(de)那片(pian)玻(bo)璃(li)承(cheng)擔。顯然，此時(shi)的(de)中(zhong)空(kong)(kong)玻(bo)璃(li)承(cheng)受(shou)荷載能(neng)力(li)將會明顯下(xia)降(jiang)。

3.環境溫、壓差對(dui)中空玻璃承載性能(neng)的(de)影響

即使不受外荷載作用，由于中(zhong)空(kong)玻璃(li)(li)(li)的生(sheng)產地(di)域環境(jing)與使用地(di)域環境(jing)存在(zai)差別，也會導致中(zhong)空(kong)玻璃(li)(li)(li)中(zhong)空(kong)層(ceng)氣體的膨(peng)脹或(huo)收(shou)縮，直接導致兩(liang)片(pian)玻璃(li)(li)(li)原片(pian)產生(sheng)變形和(he)附加應力(li)，嚴(yan)重時(shi)會使兩(liang)片(pian)玻璃(li)(li)(li)相互磕碰在(zai)一起，甚至導致玻璃(li)(li)(li)破(po)裂。

綜上所述，中空玻璃的承載能力有賴于玻璃板的強度、剛度和中空層的密封性；在均布載荷下，中空玻璃外、內兩面的受力不同，外面玻璃受力大，后面受力小，尺寸越小越明顯；中空玻璃的邊長大于厚度的150倍時，兩面玻璃的受力趨于接近；中空層氣體泄漏失效后，中空玻璃承載變形性能變化明顯，采用通過給中空玻璃施加集中載荷，測量內、外片撓度或中空層厚度的變化可識別中空氣體層是否密封良好。試驗及現場檢測結果證明，此方法及檢測裝置可方便、快捷、可靠地檢測中空玻璃的密封性能。
