從工程實踐可以看出，基層墻體溫度對聚氨酯的發(fā)泡效率也有很大的影響。噴涂過程中，如果環(huán)境溫度和建筑物基層墻體溫度都非常低，硬泡聚氨酯***遍噴涂完后，反應熱量會迅速被基層吸收，從而減少了材料的發(fā)泡量。因此，在施工時應盡量縮短中午休息時間，在施工安排過程中宜合理安排工序，以保證硬泡聚氨酯的發(fā)泡率。硬質(zhì)聚氨酯泡沫是異氰酸酯和組合聚醚雙組分混合反應生成的高分子產(chǎn)品。其中異氰酸酯組分很容易和水反應生成脲，如果聚氨酯中脲鍵含量升高，則泡沫塑料將變脆，泡沫與基材的粘結力降低。因此，要求待噴基材表面清潔干燥，相對濕度小于80%，且無銹、無粉塵、無污染、無潮氣，雨天不得施工。若有露或霜，應予以去除和干燥。

做墻面找平層厚度灰餅，每灰餅之間的距離按1.5m左右間隔粘貼。灰餅可用膠粉聚苯顆粒漿料做，也可用廢聚苯板裁成50mm×50mm小塊粘貼。待垂直方向灰餅固定后，在兩水平灰餅間拉水平控制通線，具體做法為將帶小線的小園釘插入灰餅，拉直小線，使小線控制比灰餅略高1mm，在兩灰餅之間按1.5m左右間隔水平粘貼若干灰餅或沖筋。 </p> <p> 每層灰餅粘貼施工作業(yè)完成后水平方向用5m小線拉線檢查灰餅的一致性，垂直方向用2m托線板檢查垂直度，并測量灰餅厚度，沖筋厚度應與灰餅厚度一致。用5m小線拉線檢查沖筋厚度的一致性，并作記錄。高濕或暴曬下嚴禁作業(yè)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">硬泡聚氨酯（PU）保溫材料是由異氰酸酯與多元醇反應制成的一種具有氨基甲酸酯鏈段重復結構單元的聚合物。由于其保溫性能良好，防水性能優(yōu)異，廣泛應用于外墻保溫、屋頂保溫以及冷庫、糧庫、檔案室、管道、門窗口等特殊部位的保溫。聚氨酯硬泡在國外被大量應用于屋面和墻體保溫，主要應用形式有復合板材、現(xiàn)場噴涂兩類。英國早在上世紀60年代就已將聚氨酯硬泡應用于墻體和屋面。美國1996年建筑用硬泡占硬泡總耗用量的49%，家用、商用冰箱等設備*占23.5%。另據(jù)美國聚氨酯工業(yè)協(xié)會信息，為了達到節(jié)能50%～70%的目標，美國房屋保溫系統(tǒng)所采用的保溫材料由玻璃纖維普遍轉(zhuǎn)向聚氨酯保溫材料，以充分利用聚氨酯保溫材料良好的保溫性能和防水性。聚氨酯鴨舍保溫，延長鋼管使用壽命，支撐工作管并能承受一定的外部荷載。昭通噴涂冷凍庫施工價格</p><p
