As for the cement pipe equipment that is commonly used in our daily life, it is very important to ensure its operation quality in operation. In our usual use of cement pipes, they are mostly used for some pollution flashover emissions. In some cases, the discharged substances will have certain acidity and corrosivity. This is about the quality problems of the use of cement pipes in the long-term use. The following is a small pipe manufacturer of cement pipes. Causes of corrosion on application.
Cement pipes that have been laid underground for a long time are generally used well. However, when there is a corrosive medium inside or outside, corrosion will occur, leading to damage. There are various reasons for the corrosion of cement pipes, including daily sewage, industrial wastewater, and corrosive media in the soil. In recent years, due to the addition of proteins in daily sewage, the general use of synthetic detergents and the increase in water temperature, and the complexity of industrial wastewater. Whether it is a split cement pipe, a sewage pipe or a combined cement pipe, corrosion is A serious problem.
The acid substances and calcium hydroxide in the cement will have a neutralization reaction, and the product will be loose and swollen, and it will be easily hydrolyzed and powdered when it encounters water. As a result, the concrete or plaster layer is gradually disintegrated by corrosion, so the cement should not be corroded by acids. Where acidic materials or containers are touched, acid-resistant mortar and acid-resistant concrete should be used. Slag cement, pozzolan cement and fly ash cement all have good acid resistance. These three cements should be preferentially used to prepare acid-resistant mortar and concrete. Projects that strictly require resistance to acid corrosion are not allowed to use general cement.
