| 耐酸胶泥施工中的关键技术措施 Key technical measures in acid resistant mortar construction 耐酸胶泥施工关键是“干燥”,因为它的固化过程就是使生成的Si(OH)4逐渐脱水的过程。施工中特别要重视的是防水、防潮、保持干燥、干燥养护。这往往是决定成败的主要原因。为此需要采取相应的措施。 The key to acid-resistant cement construction is "drying" because the curing process is the gradual dehydration of the resulting Si (OH) 4. In construction, special attention should be paid to waterproofing, moisture-proof, keeping dry and dry curing. This is often the main reason for success or failure. Therefore, corresponding measures should be taken. 1)由于电厂、变电站的蓄电池室一般设在建筑物的底层,而底层的地坪、墙面都比较潮湿,水份很容易通过泥土和砖、石、混凝土的孔隙产生毛吸现象。为了防止这些现象发生,可采取两种措施。一是施工时沿外墙挖一条较深的排水沟,使附近土壤中的水流入沟中排走,减少泥土中的含水量,也就减少了室内地坪、墙面的潮湿来源。二是砌筑砖墙时采用防水砂浆做好防潮层。在混凝土地坪下做一层沥青卷材防水层,以此切断潮源。 1) Because the storage battery room of power plant and substation is usually built in the bottom of the building, and the floor and wall of the bottom are relatively humid, moisture can easily be absorbed through the pores of soil and brick, stone and concrete. In order to prevent these phenomena, two measures can be taken. One is to dig a deep drainage ditch along the outer wall during construction, so that the water in the nearby soil flows into the ditch and drains away, reducing the moisture content in the soil, thus reducing the humidity source of indoor floor and wall. Two, when building brick walls, waterproofing mortar is used to make moistureproof layer. A waterproof layer of asphalt coiled material is made under the concrete floor to cut off the tidal source. 2)施工前可用竹席等材料将窗封闭,一方面减少室外潮湿空气的进入,另一方面有利于室内烘烤出的水蒸气排出。 2) Bamboo mats and other materials can be used to close the windows before construction, on the one hand to reduce the entry of outdoor humid air, on the other hand, conducive to the discharge of indoor baking steam. 3)施工最好选择在气候干燥的季节进行,但无论何时施工,都要事前在室内加热烘烤,烘烤时间因各种条件不同而异,一般以内墙反面干燥为准。当然,如果时间允许,越干燥越好。热源最好使用无尘热源,如电炉等。 3) Construction is best carried out in dry season, but whenever construction is carried out, it is necessary to bake indoors in advance. The baking time varies with various conditions, and the reverse drying of the interior wall is generally the standard. Of course, if time permits, the drier the better. Heat sources are best to use dust-free heat sources, such as electric stoves. 4)最好能在砌筑层表面事先根据瓷砖尺寸弹出或划出每块瓷砖的具体位置,将需要切割的瓷砖切割好。这样便于施工人员有条不紊地连续操作。 4) It is better to be able to lay the surface in advance according to tile size pop-up or delimit the specific location of each tile, the ceramic tile will need to be cut well. This facilitates the orderly operation of the construction workers. 5)施工前应将挑选出的瓷砖清洁并干燥。 5) the tiles should be cleaned and dried before construction. 6)施工人员进入室内应换干净工作鞋,拌料人员应戴口罩(氟硅酸钠粉有毒) 。 6) the construction workers should wear clean work shoes when entering the room, and the mixing personnel should wear masks (toxic sodium fluosilicate powder). 7)砌筑耐酸瓷砖时要求采用挤浆法铺砌,将空气挤出。耐酸胶泥砌筑厚度控制在8mm 左右。 7) when building acid resistant tiles, it is required to use compaction method to pave the air. The thickness of acid resistant masonry is controlled at about 8mm. 8)施工时室温以20 ℃左右为宜。 8) it is advisable to use room temperature at around 20 C during construction. |
