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 is mostly used for some pollution flashover emissions. In some cases, the discharged substances will have a certain acidity and corrosivity. This is about the quality of the cement pipe in the long-term use will affect the quality of its use, the following editor of the cement pipe manufacturer Xiaobian will take a look at the cement Causes of corrosion during pipe operation.
Cement pipes that have been laid underground for a long time are well used under normal circumstances. However, when there is a corrosive medium inside or outside, corrosion will occur, resulting in damage. The reasons for the corrosion of cement pipes are various, including daily sewage, industrial wastewater, and corrosive media in the soil. In recent years, due to the addition of protein in daily sewage, the general use of synthetic detergents, the increase of water temperature, and the complication 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 substance and calcium hydroxide in the cement will undergo a neutralization reaction, and the volume of the product will be loose and swelled, 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 used, 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 types of cement should be preferentially used to make acid-resistant mortar and concrete. Projects that strictly require resistance to acid corrosion are not allowed to use general cement.
