The important position of cooling tower anticorrosion in modern engineering construction

  Reasons for the anti-corrosion leakage repair of the cooling tower:o6OCooling tower noise reduction treatment manufacturer

  The anti-corrosion of cooling tower occupies an important position in modern engineering construction, but the cracks in the anti-corrosion construction of cooling tower are more common, mainly caused by our insufficient attention to the changes in the temperature stress of cooling tower anti-corrosion. The causes and treatment measures of anti-corrosion cracks in cooling towers are analyzed as follows:o6OCooling tower noise reduction treatment manufacturer

  1. Causes of crackso6OCooling tower noise reduction treatment manufacturer

  There are many reasons for cracks in cooling tower anti-corrosion, mainly due to temperature and humidity changes, brittleness and unevenness of cooling tower anti-corrosion, unreasonable structure, unqualified raw materials (such as alkali-aggregate reaction), template deformation, and foundation failure Uniform settlement, etc. In the early stage of cooling tower anticorrosion, cement emits a large amount of heat of hydration, and the internal temperature continues to rise, causing tensile stress on the surface. In the later cooling process, due to the constraints of the foundation or the original coagulation, tensile stress will appear inside the cooling tower anti-corrosion, and at the same time, it will cause great tensile stress on the anti-corrosion surface of the cooling tower. When these tensile stresses exceed the anti-cracking ability of the cooling tower, cracks will appear. In many cooling towers, the internal humidity changes little or slowly, but the surface humidity may change greatly or change drastically. Cooling tower anti-corrosion is a brittle material, the tensile strength is about 1/10 of the compressive strength, due to uneven raw materials, unstable water-cement ratio, and segregation in the process of transportation and pouring, in the same cooling tower anti-corrosion Its tensile strength is uneven, and there are many weak parts prone to cracks. In the anti-corrosion of steel cooling tower, the tensile stress is mainly borne by the steel, and the anti-corrosion of the cooling tower is only the compressive stress. Generally, the design requires no tensile stress or only a small tensile stress. However, due to temperature changes in the construction of cooling tower anti-corrosion, considerable tensile stress is often caused inside the cooling tower's anti-corrosion. Sometimes the temperature stress can exceed the stress caused by other external loads. Therefore, it is extremely important to understand the change law of temperature stress for reasonable structural design and construction.o6OCooling tower noise reduction treatment manufacturer

  The cooling tower chassis is the place where the water is filled. Water leakage will occur when the cooling tower chassis is consumed for a long time. So what is the cause of the leakage of the cooling tower chassis?o6OCooling tower noise reduction treatment manufacturer

  1. After a long period of scouring, the glass cloth seal was damaged at the interface between the plate and the plate of the passing water chassis. Most of the reasons were excessive use of chemicals when cleaning the cooling tower, or the cleaning of the water tower was stepped on the bottom of the tower, causing the chassis to crack. open.o6OCooling tower noise reduction treatment manufacturer

  2. The sinking of the concrete foundation and uneven stress on the water-passing site result in water leakage along the board-to-board interface of the water-passing chassis. The cooling tower often overflows, causing too much water in the water pan. Excessive load-bearing structure can also cause the chassis to break.o6OCooling tower noise reduction treatment manufacturer

  3. Part of the chassis leakage is due to the occurrence of trachoma during the production process of FRP. After a period of use, trachoma becomes the main channel for water leakage.o6OCooling tower noise reduction treatment manufacturer

  4. The internal structural support frame and packing support frame of the cooling tower, due to the hot-dip galvanizing control, will be corroded and rusted after a certain number of years of use. At this time, we need to perform anti-corrosion treatment or directly replace the cooling tower to avoid Causes the collapse of the cooling tower or the collapse of the packing occurs.o6OCooling tower noise reduction treatment manufacturer
