Cooling towers are very prone to rust, so it seems necessary to implement anti-corrosion and heat preservation projects for cooling towers. However, many companies do not pay attention to the correct construction methods when implementing cooling tower anti-corrosion work, resulting in a poor anti-corrosion effect. Or some accidents may occur, so you must pay attention to certain matters when implementing cooling tower anti-corrosion work:
1. Suspension work must be extra double insurance.
2. Perform load detection on brown ropes and pulleys before work.
3. Working at heights strictly abide by the safety operating procedures for working at heights.
4. It is strictly forbidden to work at height in the event of strong winds of level 4 and above and thunderstorms.
5. Set up prohibited zone signs in the construction area; pedestrians are strictly forbidden to pass; it is strictly forbidden to leave and send special personnel for guardianship.
6. The tools and raw materials used at high altitude should be strictly fixed in accordance with the regulations during hoisting and use to ensure that there is no fall; the safety belt should be pulled around the cylinder.
Therefore, attention should be paid to the anti-corrosion of cooling towers, double insurance should be added when carrying out suspension work, safety should be paid attention to when working at heights, operations should be carried out in accordance with the correct method, and prohibited zone signs should be placed in the construction area.
Do you know how to choose anti-corrosion materials during the construction of cooling tower anti-corrosion projects?
1. Coating maintenance raw materials should have corresponding elasticity, cooling tower anticorrosion can resist the erosion of carbon dioxide and sulfur dioxide, and the color tone can be adjusted.
2. During the construction of the cooling tower anticorrosion project, the repair material must be a high-performance cement base material. The anti-corrosion of the cooling tower must have high compactness and strong corrosion resistance. The anti-corrosion of the cooling tower should have the effect of preventing steel corrosion.
3. During the anti-corrosion construction process, the anti-corrosion material of the cooling tower should have good air permeability to ensure that the moisture in the structure can be routinely dissipated to the outside without destroying the protective layer, thereby causing the protective layer to be ineffective. The anticorrosive concrete structure of the cooling tower has been rusted and corroded by harmful gases caused by the combustion of intermediate water and fuel, which in turn caused the corrosion of the cooling tower. Under normal circumstances, we pay more attention to the maintenance of the inner wall and ignore the cooling tower. Maintaining the rust of the outer wall makes the formation and development of diseases of the outer wall far more serious than that of the inner wall. Therefore, the cooling tower must be protected from corrosion.
4. The combined compressive strength of the cooling tower anticorrosive repair raw materials and the basic must exceed 1.2 MPa, the compressive strength must be higher than the original concrete, and the shrinkage rate must be as small as possible.
5. The anticorrosive, waterproof and anticorrosive building materials of the cooling tower should have an expansion coefficient similar to that of the foundation concrete to ensure that the foundation concrete will not form relative displacement under the effect of temperature stress.
6. The basic requirements for waterproof and anticorrosive raw materials are not high. As long as they are flat, they don't need to be smooth, because the surface of the cooling tower itself is rough.
Anticorrosion and waterproofing of cement-based buildings, movable zones, foundations, pavements, bridge piles, railway lines, seaports, wharves, coal mines, oilfield drilling, fold zones, water towers, pools, cooling towers, sewage pools, and drinking water pools Engineering; new and old civil buildings, roofs, toilets, gutters, balconies, exterior walls, underground garages, warehouses, tunnels, anti-corrosion and waterproofing, and irrigation of various bridge grouting joints and various expansion joints; various metal pipes, steel bars , Concrete anti-corrosion engineering can avoid steel corrosion and increase the working time of concrete.
