近年(nian)來，擠塑(su)板(ban)在我國開始廣泛使用(yong)，主(zhu)要運用(yong)于建筑工(gong)程(cheng)和水(shui)利工(gong)程(cheng)。聚(ju)苯乙烯(xi)泡沫塑(su)料分為膨脹性(xing)EPS和連續性(xing)擠出型(xing)XPS兩種(zhong)，與EPS板(ban)材相(xiang)比，XPS板(ban)是(shi)*三(san)代硬(ying)質發泡保溫材料，從工(gong)藝上它克服EPS板(ban)繁雜(za)的生產工(gong)藝，具(ju)有(you)EPS板(ban)無法替(ti)代的優越性(xing)能。它是(shi)由(you)聚(ju)苯乙烯(xi)樹脂及其(qi)它添加劑經(jing)擠壓(ya)過程(cheng)制造出的擁有(you)連續均勻表層(ceng)及閉孔(kong)式(shi)蜂窩(wo)結構(gou)的板(ban)材，這(zhe)些蜂窩(wo)結構(gou)的厚板(ban)，完全不(bu)會出現空隙，這(zhe)種(zhong)閉孔(kong)式(shi)結構(gou)的保溫材料可(ke)具(ju)有(you)不(bu)同的壓(ya)力（150-500Kpa）同時擁有(you)同等低值的導熱系數(shu)（僅為0.028W/M.K）和經(jing)久不(bu)衰(shuai)的優良(liang)保溫和抗(kang)壓(ya)性(xing)能，抗(kang)壓(ya)強度可(ke)達220-500Kpa。
XPS擠塑保(bao)溫板(ban)(ban)表(biao)面(mian)不能有油污和大(da)量明水(shui)，并(bing)應清(qing)除表(biao)面(mian)上的水(shui)泥漿和浮灰。施(shi)工時，用膩子(zi)刮(gua)板(ban)(ban)將配置好的膠料刮(gua)抹(mo)于(yu)擠塑板(ban)(ban)表(biao)面(mian)，厚度為(wei)1mm，用力(li)要(yao)均(jun)勻，使(shi)膠料均(jun)勻分布在擠塑板(ban)(ban)的表(biao)面(mian)。擠塑板(ban)(ban)間的縫隙(xi)宜小(xiao)于(yu)等(deng)于(yu)3㎜，嵌(qian)入縫隙(xi)內的水(shui)泥漿清(qing)除深度大(da)于(yu)等(deng)于(yu)10㎜，擠塑板(ban)(ban)間的縫隙(xi)用NP中性(xing)硅酮密封膠或(huo)JS擠塑板(ban)(ban)界面(mian)劑(ji)嵌(qian)填飽滿。
XPS擠(ji)塑保溫板(ban)開(kai)(kai)孔外墻外側(ce)模板(ban)就(jiu)位(wei)(wei)后(hou)，根(gen)據外模穿(chuan)墻螺栓的位(wei)(wei)置(zhi)，用擠(ji)塑板(ban)開(kai)(kai)孔器將擠(ji)塑板(ban)開(kai)(kai)洞(dong)，擠(ji)塑板(ban)開(kai)(kai)孔器應旋轉推進，保證開(kai)(kai)洞(dong)的尺寸規矩，并不(bu)損傷(shang)擠(ji)塑板(ban)。開(kai)(kai)洞(dong)后(hou)安穿(chuan)墻拉桿及套管(guan)。內模就(jiu)位(wei)(wei)將外墻內側(ce)模板(ban)按(an)預定位(wei)(wei)置(zhi)就(jiu)位(wei)(wei)，用常規方法合模即可。擠(ji)塑保溫板(ban)豎排至門、窗口時，可根(gen)據需要橫綁(bang)在(zai)外墻面上，使其不(bu)出現細窄拼條。
XPS擠(ji)(ji)塑(su)保溫(wen)(wen)板(ban)在外(wai)(wai)模上口樓(lou)(lou)板(ban)厚度(du)范圍內(nei)要放L型鍍鋅鐵皮，其作用(yong)是保護保溫(wen)(wen)板(ban)上口，又使墻體澆(jiao)筑時混(hun)(hun)凝土(tu)(tu)不會填入(ru)樓(lou)(lou)板(ban)段擠(ji)(ji)塑(su)板(ban)的(de)燕尾槽內(nei)。內(nei)外(wai)(wai)模板(ban)拆(chai)除后，支完(wan)樓(lou)(lou)板(ban)模板(ban)和綁完(wan)鋼筋，利用(yong)外(wai)(wai)墻穿孔螺栓(shuan)，安裝外(wai)(wai)墻輔(fu)(fu)助(zhu)模板(ban)，即由擠(ji)(ji)塑(su)板(ban)與輔(fu)(fu)助(zhu)外(wai)(wai)模共(gong)同(tong)起樓(lou)(lou)板(ban)側模的(de)作用(yong)。澆(jiao)筑樓(lou)(lou)板(ban)混(hun)(hun)凝土(tu)(tu)時，混(hun)(hun)凝土(tu)(tu)填入(ru)擠(ji)(ji)塑(su)板(ban)的(de)燕尾槽，樓(lou)(lou)板(ban)混(hun)(hun)凝土(tu)(tu)與擠(ji)(ji)塑(su)板(ban)形成咬和連接(jie)，待拆(chai)除輔(fu)(fu)助(zhu)模板(ban)后，整塊擠(ji)(ji)塑(su)板(ban)就與外(wai)(wai)墻結為一(yi)體，形成了外(wai)(wai)墻的(de)外(wai)(wai)保溫(wen)(wen)層。
外(wai)(wai)墻面(mian)(mian)(mian)局部損傷的(de)(de)擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)，應將(jiang)其(qi)輪廓裁切成矩形(xing)，用(yong)周圈抹(mo)(mo)JS界面(mian)(mian)(mian)劑相應形(xing)狀(zhuang)(zhuang)的(de)(de)擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)嵌填補齊。輔助(zhu)模板(ban)(ban)(ban)拆除(chu)后，對(dui)外(wai)(wai)漏的(de)(de)擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)應及時(shi)刮抹(mo)(mo)界面(mian)(mian)(mian)劑。遭水(shui)泥砂(sha)漿污染的(de)(de)擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)表面(mian)(mian)(mian)，在刮抹(mo)(mo)JS擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)界面(mian)(mian)(mian)劑前應用(yong)粗砂(sha)紙(zhi)打磨(mo)清潔(jie)。季節性施工時(shi)，擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)可以起到(dao)外(wai)(wai)墻模板(ban)(ban)(ban)蓄熱(re)保溫材(cai)料的(de)(de)作(zuo)用(yong)，但當環境溫度低于5℃時(shi)，擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)表面(mian)(mian)(mian)應刮抹(mo)(mo)防凍型JS-2擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)界面(mian)(mian)(mian)劑，技術指(zhi)標應達到(dao)-15℃。雨期施工時(shi)，應在擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)表面(mian)(mian)(mian)刮抹(mo)(mo)JS-1擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)界面(mian)(mian)(mian)劑，刮抹(mo)(mo)應在無明水(shui)的(de)(de)狀(zhuang)(zhuang)態下(xia)進(jin)行。若(ruo)處(chu)在烈日(ri)暴曬下(xia)，擠(ji)塑(su)(su)(su)板(ban)(ban)(ban)表面(mian)(mian)(mian)宜用(yong)濕布擦拭，輕微潤濕陰干。刮抹(mo)(mo)界面(mian)(mian)(mian)劑，宜適當遮陽，刮抹(mo)(mo)完(wan)畢后，待表面(mian)(mian)(mian)初步(bu)結硬，宜用(yong)噴霧器噴水(shui)養護4h。
