| 粘砌耐酸砖要注意错缝。 Attention should be paid to the wrong joints in the acid-proof bricks. 3．施工前对金属设备应进行除锈、去污等，砖结构应洗刷干净，碱性普通水泥结构的表面应先用酸中和 3. Before construction, metal equipment should be rusted and decontaminated, brick structure should famenb.89ix.comqiexiaoyou.89ix.comjiareguant.89ix.comkongzhiqiz.89ix.comguolvmian.89ix.comfeibiao men.89ix.combe washed clean, and the surface of alkaline ordinary cement structure should be neutralized by acid first. 后用水洗净，再加热干燥，一般要求水份低于4％以下。After washing with water, and then heating and drying, the water content is generally required to be less than 4%. 4．耐酸水泥应在10℃以上温度中硬化，并在空气中养护10—20天左右，（冬天时间较长）养护期间切忌 4. Acid-resistant cement should be hardened at temperatures above 10 C and maintained in air for 10-20 days or so. (Winter is longer) During the curing period, avoid it. 遇蒸汽、水等，不得被太阳直接曝晒，以防止发生龟裂，如有龟裂即行修补。 When encountering steam, water, etc., it is not allowed to be directly exposed to the sun to prevent cracks. If cracks occur, they should be repaired. 5．养护干燥后要进行酸化处理，其方法是以 40％硫酸涂刷其表面，每4小时一次，每次析出的结晶物应 5. After curing and drying, acidizing treatment should be carried out. The method is to coat the surface with 40% sulphuric acid, once every 4 hours. The crystals precipitated from each time should be treated by acidizing treatment. 在下次涂刷前刮去，直至无结晶析出为止，酸处理完毕合即可交付使用。 Scrape off before the next brush until no crystalline precipitation occurs. The acid treatment is completed and can be delivered for use. |
