Precautions in the process of anti-corrosion construction of sewage tanks Precautions in the process of anti-corrosion construction of sewage tanks The anti-corrosion engineering of sewage tanks is mainly due to the chemical and chemical constituents of acid and alkali discharged from the factory. Acids and alkalis will Sewage tank capping is very corrosive. If the sewage tank is not covered with anti-corrosion, then the damage caused by the corrosion of the acid-base pool is immeasurable, so it is indispensable to cover the anti-corrosion project. So what are the precautions in the construction process of the sewage pool anti-corrosion project?
1. Sealing the bottom layer: On the surface of the treated base layer, evenly coating the sealing material, there shall be no defects such as missing drawings and hanging, and the natural curing should not be less than twenty-four hours.
2. Repair layer: In the unevenness of the base layer, it should be repaired and filled with resin cement material, and then the base layer should be repaired with resin glue.
3. The construction of the continuous resin FRP base layer in the anti-corrosion construction of the sewage tank capping factory shall comply with the following regulations: the glass fiber cloth shall be trimmed, and the polyester cloth shall be pretreated with anti-shrinkage. Firstly apply a layer of lining rubber evenly, then lining a layer of fiber reinforced material, it must be affixed, and then coated with a layer of rubber, and then lined with a layer of fiber reinforced material, when continuously lining, two layers The joints of the fiber reinforced materials shall be staggered, the staggering distance shall not be less than 50 mm, and one or two layers of fiber reinforced materials shall be added at the yin and yang angles. The sewage pool is covered with the number of layers or thickness of the continuous laying layer of the manufacturer, so as not to cause slippage, no shell after solidification, and delamination. The number or thickness of the lining layer is continuously laid in one time so as not to cause sag, and it is not limited by shelling or delamination after curing. After the previous continuous lining is cured, the next continuous lining construction is carried out. After continuous lining to the required number of layers or thickness, the cover layer should be applied for 24 hours. In addition to the precautions described above, in the construction process of the sewage tank capping anti-corrosion project, the safety technical regulations must be strictly implemented, and the construction personnel should be trained in advance to avoid engineering errors and delay the handover time.
