施工要點
先對施工(gong)(gong)物表(biao)面做(zuo)防腐(fu)處理→充分攪拌(ban)均勻(yun)防火涂(tu)料→施工(gong)(gong)以(yi)刷涂(tu)為主,施工(gong)(gong)第(di)一遍(bian)厚(hou)度為0.10-0.15mm為宜,表(biao)干后(hou)進行第(di)二次(ci)施工(gong)(gong),涂(tu)層厚(hou)度以(yi)0.15-0.20mm為宜,以(yi)后(hou)各遍(bian)施工(gong)(gong)涂(tu)層厚(hou)度應控制在(zai)0.20mm左右(you),直至(zhi)達(da)到規定厚(hou)度,每次(ci)施工(gong)(gong)時間間隔以(yi)涂(tu)層不沾手為準(zhun)(一般在(zai)18-24小時左右(you))。
驗收注意
涂層當平整(zheng),無(wu)明(ming)顯凹陷,粘結牢固,無(wu)粉化、松(song)散和浮漿,乳突已剔除,無(wu)漏涂、脫粉、明(ming)顯裂縫等。用0.75~1kg榔頭輕擊涂層檢測其強度等,用1m直尺檢測涂層平整(zheng)度。
